DARLIE LYNN ROUTIER, Appellant

v.

THE STATE OF TEXAS




ON APPEAL IN CAUSE NO. F96-39973-J
FROM THE CRIMINAL DISTRICT COURT NO. 3
OF DALLAS COUNTY


 Price, J., delivered the opinion of the Court in which Keller, P.J., and Meyers,
Johnson, Keasler, Holcomb and Cochran, J.J., joined.  Womack and Hervey, J.J.,
concurred in the result.

O P I N I O N


	This is an appeal from an order denying the appellant's motion for post-conviction
DNA testing in a capital-murder case. (1)  We will vacate the convicting court's order and
remand the cause for limited DNA testing, as specified in this opinion.
PROCEDURAL POSTURE  (2)
	The appellant was convicted of stabbing her own son, Damon Routier, to death. 
Damon was younger than six years of age at the time. (3)  Damon's older brother, Devon, was
also stabbed to death.  The appellant testified that she was sleeping on a couch in the family
room in the downstairs of her home and that her sons were asleep on the floor in front of the
television.  She awoke to discover a stranger departing through the kitchen and utility room
and out through the garage, leaving a bloody butcher knife from the kitchen behind on the
utility room floor.  She herself suffered a number of wounds, including a slash across her
neck that came perilously close to severing her carotid artery.  She denied having stabbed her
sons.  The State presented circumstantial evidence suggesting that there was no intruder, that
the crime scene had been "staged," that the appellant had inflicted the wounds on herself, and
that she had some pecuniary motive to murder her children.  The jury found the appellant
guilty of capital murder, and she was sentenced to death.  We affirmed her conviction and
sentence on direct appeal. (4)
	After her conviction became final, but while her state post-conviction application for
writ of habeas corpus was pending, the appellant filed a motion for post-conviction DNA
testing under Chapter 64 of the Texas Code of Criminal Procedure.  She requested the testing
of certain biological materials the results of which she contends will bolster her claim that
an intruder was in the house and undermine the plausibility of the State's evidence that the
crime scene was "staged."  The trial court found that the evidence that the appellant wished
to test had been adequately preserved so that DNA testing was available and that the
evidence had been maintained by a proper chain of custody. (5)  In addition, there can be no
question that the identity of the killer is in question. (6)
	Nevertheless, the trial court ultimately denied the appellant's motion, finding against
the appellant on two specific issues.  First, the trial court concluded that the appellant had
failed to establish by a preponderance of the evidence that the jury would not have convicted
her if exculpatory results from the testing she now seeks had been presented to it during
trial. (7)  Second, the trial court made a finding of fact that DNA testing was available at the
time of the appellant's trial and that the evidence she now seeks to have tested was either
actually tested pretrial or else could have been tested at that time but was not. (8)  In her appeal,
the appellant challenges both bases for denying her motion.
	The appellant lists nine items of evidence recovered from the scene that she contends
she should now be allowed to test.  She contends that, had the jury known of exculpatory
results from the collective DNA testing of these various evidentiary items, it more likely than
not would not have convicted her.  The State argues that the appellant could and should have
requested that at least some of these items be subjected to DNA testing at the time of trial. 
Before addressing the question of whether it is more probable than not that the appellant
would not have been convicted had the results of the testing she now seeks been exculpatory,
we deem it appropriate first to determine which of the nine items would qualify for post-conviction testing under the criteria of Article 64.01(b).   Only those items that qualify for
testing under these threshold criteria should be included in the collective calculus for
determining whether the appellant would not have been convicted.  We will therefore address
the trial court's second holding first.
ARTICLE 64.01(b)
The Statute and Standard of Review
	Under Article 64.01(b), a convicted person may request the convicting court to permit
forensic DNA testing of evidence containing biological material that was in the State's
possession during trial if that evidence:

	was not previously subjected to DNA testing because DNA testing was
not available; (9) or
 	was not previously subjected to DNA testing because DNA testing was
available, but not technologically capable of providing probative
results; (10) or
 	was not previously subjected to DNA testing, through no fault of the
convicted person, for reasons that are of a nature such that the interests
of justice require DNA testing; (11) or
 	was previously subjected to DNA testing, but can be subjected to
testing with newer testing techniques that provide a reasonable
likelihood of results that are more accurate and probative than the
results of the previous test. (12)

If one or more of the items that the appellant wishes to subject to post-conviction DNA
testing meet any of these criteria, the trial court may order such testing--but only if the
appellant also satisfies other statutory predicates, including a showing, by a preponderance
of the evidence, that she would not have been convicted if exculpatory results had been
obtained from DNA testing of as many of the nine items as meet the Article 64.01(b)
criteria. (13)  In reviewing the trial court's ruling, this Court ordinarily gives "almost total
deference" to the trial court's resolution of questions of historical fact and application-of-law-to-fact issues that turn on witness credibility and demeanor, but we consider de novo all
other application-of-law-to-fact questions. (14) 
Preliminary Matters
	Before getting down to the specifics of the appellant's claims with regard to the
biological materials for which she seeks to obtain post-conviction DNA testing, we must first
address several general matters that will inform our analysis of all of her claims.  We begin
with the appellant's apparent assumption that she can invoke Article 64.01(b)(1)(B)'s no-fault provision to argue generally that she was not at fault for failing to obtain DNA testing
simply because all of the biological materials were in the State's control.  The appellant was
given access to all of the State's evidence, including biological evidence, prior to trial.  She
does not allege or prove that she herself ever sought to obtain any of the biological material
from the State, or any funding from the convicting court, for the specific purpose of
conducting DNA testing using the technology that was available at that time. (15)  Nevertheless,
she broadly asserts that she cannot be faulted for her failure to seek any DNA testing at the
time of trial because the State had possession of all of the biological material and did not
even reveal that it had conducted DNA testing until shortly before her trial commenced. (16) 
She seems to argue that this circumstance alone should be enough to satisfy the criteria of
Article 64.01(b), thereby allowing her to obtain all of the testing she now seeks.  We cannot
construe the statute this way.
	Post-conviction DNA testing under Chapter 64 pertains exclusively to testing of
biological material that "was in the possession of the state during the trial of the offense[.]" (17) 
Thus, any request for post-conviction DNA testing under Chapter 64 will necessarily seek
the belated testing of biological materials that were in the State's possession at the time of
trial.  In essence, the appellant argues that because the State possessed the biological
materials, she can never be at fault for failing to seek DNA testing at the time of trial.  And
as long as a jury would not have convicted her had it been privy to the results of post-conviction DNA testing, she seems to maintain, the interests of justice will always require
testing.  For this reason, she argues, she should be allowed to obtain the post-conviction
DNA testing under Article 64.01(b)(1)(B).
	To accept the appellant's implied construction of Article 64.01(b)(1)(B), however,
would thwart the obvious legislative intent.  It would relieve all post-conviction DNA
movants from any obligation ever to seek DNA testing under technologies available at the
time of trial, as contemplated by Subsections (b)(1)(A)(i) and (b)(1)(A)(ii).  Because the
biological materials the movant seeks to subject to post-conviction testing under Chapter 64
were, by definition, in the State's possession at the time of trial, movants could always
invoke the no-fault provision of Subsection (b)(1)(B) to obtain post-conviction DNA testing
and never have to resort to Subsections (b)(1)(A)(i) and (b)(1)(A)(ii).  In other words, the
appellant's construction would effectively nullify whole portions of the statute, contrary to
the rules of statutory construction. (18)  We reject such a reading of the statute.  In the specific
analyses that follow, we will require the appellant to make a more particularized showing of
the absence of fault whenever she invokes Article 64.01(b)(1)(B).
	The second preliminary matter to which we must attend is a latent ambiguity in the
statute, the resolution of which will often determine which provision of Article 64.01(b) will
apply.  Article 64.01(a) provides for forensic DNA testing of "evidence containing biological
material."  In the instant case, there are several items of evidence that were admitted at trial
that contained multiple samples of "biological materials" capable of providing different
results.  The appellant wishes to test multiple blood stains from a tube sock, a night shirt, and
a butcher knife.  Is the "evidence containing biological material" the sock, night shirt, or
knife? Or does the statute contemplate that the "evidence containing biological material"
should be considered the individual blood stains on those evidentiary items?  The answer is
critical, for it determines whether the criteria in Article 64.01(b)(1) (governing whether
"evidence" not previously subject to DNA testing may be subjected to post-conviction DNA
testing) or (b)(2) (governing whether "evidence" that was previously subjected to DNA
testing may be retested) will apply.  For example, with respect to the tube sock, the appellant
seeks both to subject specific blood stains that have already been tested to new testing, and
to test other blood stains on the tube sock that have never been tested before.  If the
"evidence containing biological material" is construed broadly to be the tube sock, then both
requests should be governed by Article 64.01(b)(2).  But if, instead, the "evidence containing
biological material" is deemed to be the individual blood stains appearing on the tube sock,
then the appellant's request for retesting will be governed by Article 64.01(b)(2), while her
request for new testing will be governed by Article 64.01(b)(1).
	We think the latter understanding is more consonant with the apparent legislative
intent. (19)  It is clear that the Legislature meant to require defendants to avail themselves of
whatever DNA technology may be available at the time of trial.  Otherwise, there is no ready
explanation for the distinction between Article 64.01(b)(1)(A)(ii) (evidence not previously
tested may be subjected to post-conviction DNA testing if technology at the time of trial not
capable of providing probative results) and Article 64.01(b)(2) (evidence that was previously
tested may be retested if newer technology would yield more accurate and probative results). 
The Legislature could have chosen to draft a statute that would permit post-conviction testing
any time the technology improves enough to enhance accuracy and probative value,
regardless of whether either party had previously obtained available DNA testing.  But it
plainly did not.  If all of the blood stains on the tube sock (or night shirt or butcher knife)
were amenable to DNA testing at the time of trial, then the appellant should not be able to
avail herself now of the benefits of post-conviction DNA testing simply because some of
those stains were tested by the State and the technology has since improved.  As long as it
would have been apparent to the appellant at the time of trial that the other individual blood
stains on the tube sock (or night shirt or butcher knife) would (or even might) have discrete
and independent probative value, the overall import of the statute mandates that she seek
such testing at that time, or forego testing later.  Accordingly, we construe "evidence
containing biological material" to mean individual samples of biological material, even if
taken from the same physical object or source, that have (or may conceivably have) discrete
and independent probative value for purposes of the particular issues at trial. (20)
	The third preliminary matter that we must address is an apparent misconception
harbored by the convicting court, as suggested by its order denying the appellant her request
for post-conviction DNA testing.  In its order, the convicting court "finds that DNA testing
was available at the time of [the appellant's] trial and that the evidence was either tested or
could have been tested at the time of trial." (21)   This finding of fact is accurate insofar as it
goes.  But it is not dispositive of the appellant's various claims that she has satisfied the
criteria of Article 64.01(b).  Under that provision, as set out above, the appellant may well
be entitled to retest certain biological material even if it was already subjected to DNA testing
at trial, (22) and she may also be entitled to test other biological material even though it could
have been, but was not, tested at the time of trial. (23)  Because the convicting court
misconstrued or failed to apply the proper criteria for obtaining post-conviction DNA testing
under Article 64.01(b), we will review the question whether the appellant has met those
particular criteria de novo, notwithstanding the convicting court's fact finding.
The Tube Sock
	A tube sock was recovered in an alley behind, and a few houses down from, the
appellant's home.  It contained the boys' blood and other biological materials.  The
appellant's position was that the sock must have been left there by the unknown intruder as
he fled the crime scene.  The State's theory was that the appellant planted the sock there to
make it appear as if an intruder had fled down the alley.
	The appellant wants to conduct three tests with relation to the tube sock.  First, she
asks that human limb hairs found on the tube sock be subjected to Short Tandem Repeat
(STR) DNA testing (if the hair retains its root) or mitochondrial DNA testing (if it does not). 
She claims that, "[d]ue to more discriminating testing techniques, it is likely that DNA results
that were unrecoverable in 1996 may be obtained from this evidence today." (24)  She refers us
to the affidavit of her expert, Dr. Elizabeth Johnson, a forensic DNA analyst.  The appellant
does not claim that the limb hairs were previously tested.  The question, therefore, is whether
any previously available method of DNA testing was not technologically capable of
providing probative results. (25)  In her affidavit, Dr. Johnson nowhere asserts that DNA results
were "unrecoverable in 1996" using the technology then available.  She simply asserts that
"advances in DNA testing since 1996 make testing . . . likely to yield more probative results
if tested today."  For items not previously subjected to DNA testing, the standard is not
whether previous technology would yield more probative results, but whether it was capable
of yielding any probative results at all.   The appellant was not entitled to subject the limb
hairs to post-conviction DNA testing.
	Second, the appellant speculates that the tube sock might have been used to gag her
and might therefore contain additional biological material in the form of saliva.  According
to Dr. Johnson, the sock could have been subjected to a procedure known as amylase
mapping to determine the possible presence of saliva, which, if found, could have been
subjected to DNA analysis.  The appellant complains that the State did not have the sock
tested for the presence of saliva, and therefore, through no fault of hers, the DNA testing was
not done. (26)  However, the appellant has failed even to establish that there is any biological
evidence on the sock in the form of saliva.  The appellant herself never sought to have the
amylase mapping procedure performed prior to trial.  Nothing in Chapter 64 entitles her to
have it performed now as a predicate to seeking post-conviction DNA testing.  Thus, she fails
to meet her threshold burden of showing that there is even any "evidence containing
biological material" to be tested. (27)
	Third with respect to the tube sock, the appellant seeks to retest blood stains that were
already subjected to DNA testing by the State prior to trial.  Six blood stains from the sock
were tested in all.  Three of the stains matched Devon's DNA and two matched Damon's. 
One of the stains yielded no results.  In addition, she seeks to test other blood stains on the
sock that were not previously tested.
	As for the stains that were tested and did yield a result, the appellant must show that
new testing techniques will provide a reasonable likelihood of results that are more accurate
and probative than the results of the previous tests. (28)  It may well be that the new testing
techniques would yield more accurate results, in the sense that they may have a higher power
to exclude potential DNA donors.  But on the facts of this case, the appellant has not shown
a reasonable likelihood that those results would prove more probative. (29)  Given the volume
of blood at the scene that came from Devon and Damon, it seems most improbable that
newer, albeit more accurate, DNA testing would now exclude them as donors. (30)  While such
a result is remotely possible, the reasonable likelihood is that new testing will only confirm
the results of the old testing, albeit with greater accuracy. (31)  At least under these
circumstances, the appellant has not shown the new testing to be more probative, and she is
therefore not entitled to it.
	Turning to the one stain that was tested before trial but did not yield a result, the
question again is whether newer testing techniques would provide a reasonable likelihood
of results that are more accurate and probative than the results of the previous test. (32)  The
State points to testimony at trial from Judith Floyd, the forensic laboratory supervisor at Gene
Screen, that "it's not uncommon" not to get a result from a particular stain, but that "using
the D1S80 technique," which was one of the technologies available at the time of trial, "if
you retype the specimen, it's very likely you could get a result." In her second affidavit
accompanying the appellant's motion, Dr. Johnson counters that current "clean up"
procedures, which are an improvement over the "clean up" techniques available in 1996,
would make it more likely that retesting would yield a result. (33)  We think that such "clean up"
procedures fall within the ambit of the statutory reference to "newer testing techniques" in
Article 64.01(b)(2).  Even if retesting with the old DNA testing techniques would likely have
yielded a result, if no results were in fact obtained through the old testing and the likelihood
of obtaining a result is significantly enhanced by the newer "clean up" techniques, we think
that the appellant has satisfied Article 64(b)(2). (34)
	The appellant also submits that she should be permitted to conduct post-conviction
DNA testing on the remaining, previously untested blood stains on the tube sock because that
testing can now be accomplished utilizing the newer "clean up" techniques.  But any
evidence not previously subjected to DNA testing may not be subjected to post-conviction
DNA testing unless DNA testing was either completely unavailable at the time of trial or was
available but not technologically capable of providing probative results. (35)  As we have
already noted, evidence that has not been previously tested for DNA cannot be subjected to
post-conviction testing simply because new techniques become available that would yield
"more accurate and probative" results. (36)  Efficacious DNA testing was obviously available
at the time of trial to test the remaining blood stains, since five of the blood stains on the sock
were in fact successfully tested.  Therefore, the provisions of Article 64.01(b)(1)(A) do not
apply.  Whether the appellant may obtain post-conviction testing depends, then, upon
whether she has shown that they were not previously subjected to DNA testing through no
fault of her own, and that the lack of previous testing was "for reasons that are of a nature
such that the interests of justice require DNA testing." (37)  But the appellant does not even
attempt to argue that she can satisfy this provision (other than her general no-fault argument,
which we have already rejected).  She has therefore failed to show that she is now entitled
to conduct post-conviction DNA testing on the previously untested blood stains on the tube
sock.
Coffee Table Blood
	The police recovered a latent palm print on a glass-top table in the family room where
the murders occurred.  The print was embedded in dried blood.  The State's fingerprint
examiner at trial was unable to match the palm print for lack of a sufficient number of points
of comparison, but did express the opinion that, because of the size of the ridge detail, he
believed the print belonged to a juvenile or possibly a five- or six-year-old child. (38)  The
appellant claims that the State has since "abandoned" its position that the palm print probably
belonged to one of the children, and that subsequent fingerprint examinations conducted
pursuant to her initial post-conviction application for writ of habeas corpus have revealed
that the palm print belonged to none of the adults in the Routier household. (39)  On the
assumption that the palm print must therefore belong to the unknown intruder, the appellant
argues that the blood should be tested for the presence of male DNA.  She does not claim that
the blood itself will likely be shown to belong to the unknown male intruder, but that,
because the palm print is likely his, there could be biological material such as oil from his
hand mixed with the blood.  Dr. Johnson avers that newer DNA testing techniques,
specifically Y-chromosome STR testing, "could be especially useful in determining whether
a male DNA profile is present that is unrelated to the Routier male lineage."
	Even entertaining the appellant's factual assumptions about the palm print, we find
that she is not entitled to the DNA testing she presently seeks.  The appellant does not
indicate whether the dried blood in which the palm print is embedded has ever been subjected
to DNA testing.  In the absence of any indication in the record that it has, (40) we must apply
the criteria in Article 64.01(b)(1)(A)(ii), which requires the appellant to show that previously
available DNA testing was not technologically capable of providing probative results. (41)  Dr.
Johnson does not assert that the DNA technology in existence at the time of trial could not
distinguish multiple DNA sources from a single biological sample--indeed, many of the
samples that were tested for trial from various biological materials were shown by DNA
technology extant in 1996 to contain mixtures of the appellant's and her sons' DNA. (42)  Dr.
Johnson now asserts only that the present-day DNA technologies would do a better job.  We
reiterate: That is the standard for determining whether biological materials that have been
previously subjected to DNA testing may again be tested.  The appellant has failed to
establish that she is entitled to conduct post-conviction DNA tests of the bloody palm print.
Pubic Hair
	At trial, the DNA analyst from Gene Screen testified that she tested a pubic hair,
which contained a root, but was unable to obtain any results. (43)  Because the pubic hair was
previously subjected to DNA testing, the standard is whether newer techniques would be
reasonably likely to yield more accurate and probative results. (44)  Given the improved "clean
up" technologies described in Dr. Johnson's affidavit, we think the appellant has shown that
they would.
Night Shirt
	The bloody night shirt that the appellant wore on the night of the offense was
subjected to extensive DNA testing.  The results showed a D1S80 type that was consistent
with the appellant's on many of the stains that were tested.  Other stains were consistent with
Damon's or Devon's type, while still others showed a mix of the appellant's and Damon's
or Devon's type.  No other D1S80 type was revealed.  The State presented an expert on blood
pattern analysis who testified that some of blood found on the night shirt was consistent with
"cast off" blood from the appellant's acts of stabbing both Devon and Damon.
	The appellant now asks to be able to subject other areas of the night shirt to DNA
testing.  She raises two justifications.  First, she claims that the State did not establish a
sufficient number of blood stains to establish a "cast off" pattern with respect to Damon. 
Additional testing, she contends, would, as Dr. Johnson describes it, "support or refute the
State's claims that the stains" represent "cast off" blood.  In essence, the appellant seeks to
test other blood stains on the night shirt that have never been previously subjected to DNA
testing.  She therefore must satisfy one of the criteria in Article 64.01(b)(1).  But she has
neither alleged nor proved that the 1996 DNA technology was incapable of providing
probative results for other blood stains on the night shirt. (45) Further, she has not shown that
the failure to seek DNA testing under the technology available at the time of trial was not her
fault. (46)
	Second, the appellant speculates that there could be blood from the unknown intruder
on the night shirt that could be mixed with the high volume of blood on the shirt that
obviously came from her own wounds. (47)  She argues, based upon Dr. Johnson's affidavits,
that new DNA technologies, particularly the Y-chromosome STR technique, can better
differentiate male from female DNA in a mixed sample.  It is unclear to us whether the
appellant wishes to test hitherto untested areas of the night shirt, or to retest areas of the night
shirt that have been previously tested and shown to contain the appellant's D1S80 type.  She
is not entitled to test the former without either a showing that the previous technology was
incapable of distinguishing DNA from more than one contributor to a single sample, (48) or an
allegation and showing of no-fault. (49)  Obviously, the previous technology was at least
rudimentarily capable of detecting and distinguishing mixed contributors, since Gene Screen
was able to identify mixtures of the appellant's DNA and that of her sons. (50)
	On the other hand, to the extent that the appellant wishes to retest those biological
samples that the State had tested at the time of trial, she need only demonstrate that the newer
Y-chromosome STR technology provides a reasonable likelihood of results that are more
accurate and probative than Gene Screen's results.  Dr. Johnson maintains that Gene Screen's
1996 testing of the samples from the night shirt "was limited in nature in that it only utilized
the D1S80 test which was not as sensitive as today's STR tests in detecting mixtures of
DNA, nor was it as informative in power of discrimination."  This demonstrates that the
newer technology is reasonably likely to turn up evidence of an unknown intruder's DNA
that the technology extant in 1996 may not have.  The appellant should be permitted to retest
those samples of the night shirt that the State has already subjected to DNA testing.
Facial Hair
	A facial hair was recovered somewhere at the scene. (51)  Gene Screen subjected the hair
to DNA testing using the D1S80 typing technique, and it excluded as potential contributors
the appellant, her husband, and her children.  On the assumption that it must belong to the
unknown intruder, the appellant seeks to retest the facial hair utilizing the newer, more
discerning technology in order to compare the results to DNA testing of other biological
evidence she seeks to have tested, to show that it all belongs to the same unknown party. 
Because she has shown that the facial hair can now be subjected to a newer DNA testing
technique that provides a reasonable likelihood of obtaining results that are more accurate
and probative than the older DNA testing technology, (52) the appellant is entitled to subject it
to post-conviction DNA testing.
Butcher Knife
	Four areas of blood from the butcher knife, the apparent murder weapon, were tested. 
Two of the areas yielded results showing the appellant's DNA.  Another showed Damon's
DNA.  The last showed a mixture of the appellant's and Damon's DNA.  The appellant
points to the fact that not every area of the knife that had blood on it was tested, and that the
knife might also contain trace amounts of the unknown intruder's blood.  Thus, the appellant
now seeks testing of areas of the knife that were not previously subjected to DNA testing. 
Without specifically addressing the issue of fault, she argues that the remaining areas of
blood on the knife should now be subjected to newer DNA testing techniques "in the
interests of justice." (53)
	However, she made no argument to the convicting court, and presented no evidence
to show, that she was not at fault for failing to assure that every relevant area of the knife
containing biological evidence was subjected to DNA testing using the technology that was
available at the time of trial.  That technology was plainly sufficient to provide probative
results, since Gene Screen was able to obtain results for every sample of blood from the knife
that it did test.  If the appellant thought it was important at the time of trial to subject other
portions of the knife containing biological materials to DNA analysis, she could have
attempted to do so.  The appellant cannot now obtain testing "in the interests of justice" using
newer technologies when she apparently made no effort at the time of trial to utilize the
technology then available.
Rape Kit
	There is some intimation in the trial record that the appellant was sexually assaulted
by the unknown intruder and that there may have been a partial rape kit performed on her
when she was transported to the hospital. (54)  At present, however, the appellant has provided
no concrete evidence that such an examination was actually done, (55) or, if it was, that any
biological material that may have been recovered was retained.  As with the claim of saliva
on the tube sock, the appellant fails to meet her threshold burden of showing that there is
even any "evidence containing biological material" to be tested. (56)
Pillows
	There were a number of pillows on or around the couch upon which the appellant
slept.  Two blood stains from one of the pillows were subjected to DNA testing by Gene
Screen, yielding a D1S80 type that was consistent with the appellant.  In her brief, the
appellant claims that "the interests of justice and the fact that new testing methods are now
available dictate testing additional stains which could reveal the DNA of the unidentified
intruder that have not been previously tested on the pillow." (57)  The appellant made no
request, however, to have the pillow subjected to additional DNA testing under the
technology extant in 1996, even though that technology was plainly capable of providing
probative results. (58)  While she claims that the interests of justice require post-conviction
testing, she does not specifically allege, much less prove, that the previous failure to test
other blood stains on the pillow was through no fault of her own. (59)
Blood Flakes on Garage Door
	SWIFS conducted DQ alpha DNA testing upon a biological sample, denominated
"Flakes in film canister labeled, 'garage door outside.'"  No human DNA was detected using
this technology.  The appellant now claims that the flakes were dried blood recovered from
the door leading from the utility room out into the garage.  An exhibit was admitted at the
time of trial that does indeed show blood on the garage side of this door.  The appellant now
argues that the flakes that were previously tested by SWIFS should be retested using the more
modern DNA testing techniques.  Because the flakes were previously subjected to DNA
testing, the appellant must establish that newer testing techniques are available that provide
a reasonable likelihood of results that are more accurate and probative than the DQ alpha
testing. (60)  She has shown through Dr. Johnson's affidavit that with the newer STR testing
technique, along with the improved "clean up" technology, there is a reasonable likelihood
of obtaining more accurate and probative results.
Summary
	In our de novo review, we have concluded that the appellant has satisfied the criteria
under Article 64.01(b)(2) for conducting post-conviction DNA testing, using present-day
technologies, of the following biological materials:

	one blood stain on the tube sock, previously tested but yielding no
results;



the pubic hair, previously tested without results;




previously tested blood stains from the night shirt;




the facial hair;




flakes from the door from the utility room to the garage, previously
tested without results.


Before the appellant may be permitted to subject these biological materials to post-conviction
DNA testing, however, it is still incumbent upon her to establish by a preponderance of the
evidence that, assuming those tests produce exculpatory evidence, the jury would not have
convicted her in light of this additional, exculpatory evidence. (61)  This is an issue we always
review de novo, (62) and we turn to that analysis next.
ARTICLE 64.03(a)(2)(A)
	Article 64.03(a)(2)(A) was amended in 2003; the amendment applies to any motion
for post-conviction DNA testing filed after its effective date of September 1, 2003. (63)  The
appellant filed her motion for post-conviction DNA testing in November of 2003.  Under the
amended provision, "[t]he defendant must prove that, had the results of the DNA test been
available at trial, there is a 51% chance that the defendant would not have been convicted." (64) 
For purposes of this inquiry we must assume (without deciding, of course) that the results of
all of the post-conviction DNA testing to which the appellant is entitled under Article
64.01(b) would prove favorable to her. We must then determine whether there is a greater
than 50% chance that the appellant's jury would not have convicted her had it been aware
of those presumptively favorable test results.
	The facial hair and the pubic hair, by themselves, do not prove much, even if post-conviction DNA testing were to reveal that they came from the same unknown source.  The
record does not clearly reveal where in the house they were found, and there is no way to
know for sure when they may have been deposited.  However, when we combine the
presence of the hairs with the blood evidence, a clearer circumstantial picture begins to
emerge corroborating the appellant's story of an unknown intruder.  Blood from an unknown
third party male on the tube sock, the night shirt (mixed with the appellant's own blood), and
on the outer part of the door leading from the utility room to the garage--especially if it can
be said that the blood was contributed by the same unknown party who left the facial and
pubic hairs--places that unknown party at the scene at the time of the killings, and supports
the appellant's account that he fled through the utility room and out of the house by way of
the garage.  Such substantial corroboration of the appellant's exculpatory account would have
a strong tendency to engender a reasonable doubt in an average juror's mind.
	This is not to say that the inculpatory evidence was insubstantial, much less legally
insufficient. There is no lack of evidence to support the State's theory that the appellant
murdered her children and then staged the scene to try to make it look like the culprit was an
unknown intruder.  Some of the more significant circumstances that call into question the
appellant's story, as highlighted in the State's brief, include:

	twice the appellant seemed to make a point of volunteering to first
responders at the scene that she had handled the murder weapon and
thereby "had probably ruined any prints the intruder may have left"; (65)



although the appellant claimed the intruder escaped through the garage,
no blood trail could be found beyond the utility room, and the motion
sensor in the backyard was apparently never triggered; (66)

 	there was relatively little overturned furniture or property damage, and
valuable jewelry was found on a counter top between the kitchen and
family room, belying the appellant's claim that she struggled with the
intruder and suggesting "a proprietary interest" in the house and its
contents that is inconsistent with a home invasion; (67)
 	the blood and other circumstantial evidence at the scene did not
corroborate the appellant's account that after the intruder cut her as she
lay on the couch, she followed him through the kitchen and found the
butcher knife on the utility room floor; (68)
 	the appellant's night shirt had "cast off" stains of the boys' blood,
suggesting she had stabbed them; (69)
 	the house would not have been an inviting target for a home invader,
and nobody actually saw an intruder leave the scene (70)
 	there was some evidence (although contested) that the appellant and her
husband were having financial difficulties, and life insurance policies
for the boys in the amount of $5,000 apiece were found in a folder not
far from the couch; (71)



the appellant's demeanor and behavior in the aftermath of the murders
were arguably "nothing like a grieving mother"; (72) and

 	the appellant gave varying accounts of the incident and her assailant to
investigators and friends. (73)

The circumstantial evidence most detrimental to the appellant's account of an unknown
intruder involved a window screen in the garage that had been cut open.  The State's argued
that the appellant cut the screen herself to make it appear to be the intruder's means of
ingress and egress.  A bread knife was found in the knife block on the kitchen counter from
which a trace evidence analyst observed microscopic residue from the cut screen.  It is highly
implausible that an unknown intruder would have somehow gained entry to the house, stolen
the knife, exited the house, cut the screen, and then entered the house again, making sure to
return the knife to the block before attacking the appellant and her children.
	On the other hand, the State's theory is hardly unassailable.  As the appellant points
out in her brief, (74) it would have been difficult for her to have staged the scene as the State
contends, in the order in which she would have had to proceed, and in the limited time she
would have had to do it.  Even crediting the State's own evidence in the case, the jury was
confronted with two competing theories of what happened in the house that night, neither of
which is wholly consistent with the circumstantial evidence.
	We think that adding DNA evidence that would corroborate the appellant's account
of an unknown intruder to the evidentiary mix could readily have tipped the jury's verdict in
the appellant's favor.  In our estimation, DNA evidence showing that an unknown
intruder--indeed, the same unknown intruder--had left blood on the night shirt and the door
from the utility room to the garage, along with a facial hair and a pubic hair, would more
likely than not have caused the jury to harbor a reasonable doubt as to the appellant's guilt
and decline to convict her.
	The State argues that the presence of an unknown person's DNA could not have
changed the jury's verdict because "it would not refute the evidence physically linking
appellant to the murders and to the manipulation of the evidence at the scene.  At a minimum,
appellant would undoubtedly have been convicted as a party." (75)  We disagree.  The State's
circumstantial evidence tending to show that the appellant manipulated the scene is not so
compelling that the jury would more likely conclude beyond a reasonable doubt, when
confronted with DNA evidence corroborating the appellant's story of an unknown intruder, 
that she was an accomplice (or had an accomplice) to the murder of her own children.  There
is at least a 51% likelihood that the jury would have seen her as a victim herself--or at least
that it would have harbored a reasonable doubt that she was not. (76)
	Accordingly, we hold that the convicting court erred in failing to allow at least the
limited DNA testing that was permissible under Article 64.01(b).  The convicting court's
order is therefore vacated and the cause is returned to the convicting court for further
proceedings, consistent with this opinion, under Chapter 64.

2. 	 The convicting court did not formally take judicial notice of the appellate record.  However,
in its order denying the appellant's motion for post-conviction DNA testing, the convicting court did
indicate that it had considered "the evidence adduced at trial[.]" Because the current judge of the
Criminal District Court Number 3, who ruled on the motion, was not the same judge who presided
over that court at the time of trial, he could not have relied on personal recollection.  He could only

post.  However, the record does not reveal that she ever attempted to obtain funding from the trial
court to conduct DNA testing on those cuttings.

18. 	 "In enacting a statute, it is presumed that . . . the entire statute is intended to be effective[.]" 
Tex. Gov't Code (Code Construction Act) § 311.021(2).  The Code Construction Act applies

Legislature.  Id. § 311.002(2); Ex parte Torres, 943 S.W.2d 469, 473 n.5 (Tex. Crim. App. 1997).
19. 	 In construing Chapter 64, as with any other statute, we seek to effectuate the legislative
intent; and if the statute is not plain on its face, we may look to other indicia of that intent.  Kutzner
v. State, 75 S.W.3d 427, 433 (Tex. Crim. App. 2002).
20. 	 If this seems harsh, it should be remembered that the Legislature has included a fail-safe
provision in the statute.  A defendant may still be able to invoke Article 64.01(b)(1)(B) to obtain
post-conviction DNA testing if he can demonstrate that the incremental probative value of testing
a discrete item of biological material was not reasonably apparent at the time of trial, that the failure
to seek DNA testing at the time of trial was therefore not his fault, and that the interests of justice
now require post-conviction testing.
21. 	 There is no express conclusion of law in the convicting court's order that corresponds to this
fact finding.
22. 	 See Article 64.01(b)(2).
23. 	 See Article 64.01(b)(1)(A)(ii) and (b)(1)(B).
24. 	 Appellant's Brief, at 34.
25. 	 Article 64.01(b)(1)(A)(ii).
26. 	 Thus she seems to invoke Artcile 64.01(b)(1)(B).
27. 	 Article 64.01(a) ("A convicted person may submit to the convicting court a motion for
forensic DNA testing of evidence containing biological material.").
28. 	  Article 64.01(b)(2).
29. 	 Under Article 64.01(b)(2), the new testing technique must be capable of yielding a result that
is "more accurate and probative" than the old technique.  In construing statutory language, we
presume that every word has been used for a purpose and should be given effect if reasonably
possible.  E.g., State v. Hardy, 963 S.W.2d 516, 520 (Tex. Crim. App. 1997).
30. 	 There can be little doubt that the sock came from the appellant's home.  It was also shown
at trial that further DNA testing of non-blood biological evidence from the toe of the sock yielded
"a very faint typing matching the D1S80 type of" the appellant, suggesting that at some point she had
worn it.  With all the blood from the boys at the crime scene, it is hardly surprising that the DNA
testing of the blood samples on the sock yielded results consistent with Devon and Damon.
31. 	 Chapter 64 does not require us to assume that the results of new testing would prove
exculpatory in making the threshold determination, under Article 64.01(b)(2), whether new testing
techniques would be more probative than old techniques.
32. 	 Article 64.01(b)(2).
33. 	 According to Dr. Johnson:

		DNA "clean up" procedures are available today that were not in 1996. 
Inhibitors of the enzyme that drives the PCR amplification process are often
encountered in forensic samples, and although some techniques were utilized in 1996
to overcome this problem, these techniques were not always utilized by all
laboratories and when they were, success was variable.  Technology has advanced
considerably in this area, and several commercially available products are available
today such as DNA IQ by Promega and Quiagen columns.  Using a procedure such
as these has proven to significantly improve amplification of extracted DNA that
previously gave a "no result" due to the presence of inhibitors.
34. 	 In this context it is important to note that, unlike Article 64.01(b)(1)(B), Article 64.01(b)(2)
contains no "fault" provision.  Therefore, the fact that the appellant failed to seek retesting under the
old testing techniques does not prevent her from obtaining new testing now if the technology for
preparing DNA samples for testing has significantly improved in the interim, making it more likely
than before that the testing will yield results.  Any results will be "more accurate and probative" than
no results at all.
35. 	 Article 64.01(b)(A).
36. 	 Only biological evidence that was previously tested is subject to post-conviction retesting
under this standard.  Article 64.01(b)(2).
37. 	 Article 64.01(b)(1)(B). 
38. 	 The Dallas County Medical Examiner released Devon's and Damon's bodies for burial
without first taking their palm prints.
39. 	 The appellant does not cite any place in the record where the State has "abandoned" its
position at trial, nor can we find any such abandonment in the record.  The convicting court
concluded during the initial state habeas proceedings that the State's trial expert made an accurate
assessment of the probable source of the palm print, and this Court expressly adopted its findings
of fact and conclusions of law in denying the appellant habeas corpus relief.
40. 	 According to a report from the Southwest Institute of Forensic Science (SWIFS), dated
November 1, 1996, which is attached to the appellant's pleading, "flakes" from a "coffee table" were
submitted for DNA testing.  The appellant was found to be a potential contributor, while her husband
and two children were excluded as contributors.  There is no mention of another possible contributor. 
The appellant does not allege that this biological material (assuming it was blood) came from the
same coffee table (there were more than one) on which the bloody palm print was discovered, and
we can find no basis in the record before us to conclude that it was.
41. 	 Again, the appellant does not specifically argue that the failure to subject the bloody palm
print to available DNA testing at the time of trial was through no fault of her own, or that the
interests of justice require that it be tested.  For this reason we do not apply Article 64.01(b)(1)(B).
42. 	 A forensic serologist testified at trial that in the event of a mixture of biological materials,
"the DNA analyst would be able to pick up both blood types." And indeed, when Gene Screen
subjected biological materials from the appellant's night shirt and the apparent murder weapon to
DNA testing, it was able to discern both the appellant's and her sons' DNA in some of the samples.
43. 	 The appellant makes various allegations about where the pubic hair was discovered (e.g.,"in
the kitchen," "in the vicinity of [the] living room"), but cites to nowhere in the appellate record that
reveals where it actually came from.  Nor can we determine where it was found from our review of
the appellate record.  The closest the record comes to revealing where the pubic hair was found is
an awkward question from defense counsel to the DNA analyst from SWIFS that seems to assume
that it was found in the "den."  A Gene Screen report that is attached to the appellant's motion, dated
January 7, 1997, indicates that the DNA analyst who actually tested the pubic hair obtained it from
the SWIFS trace evidence analyst on November 21, 1996, but was unable to obtain a D1S80 type. 
44. 	 Article 64.01(b)(2).
45. 	 Article 64.01(b)(1)(A)(i).
46. 	 Article 64.01(b)(1)(A)(ii).  Elsewhere in her brief, the appellant generally alleges that,
because the State did not disclose the results of its own DNA testing until "shortly before her trial,"
Appellant's Brief, at 14, she cannot be faulted for failing to seek DNA testing of her own.  It could
perhaps be argued (although the appellant does not make this argument specifically with respect to
the night shirt) that the appellant could not have known until this time that it was necessary to
conduct further testing on the night shirt in order to refute the State's "cast off" theory.  But the
appellant received a copy of the SWIFS report in the latter part of November, 1996, which contained
results of preliminary DNA testing on the night shirt.  The first Gene Screen report is dated
December 2, 1996.  It reflects that eighteen blood stains from the night shirt were analyzed.  The first
day of the guilt phase of trial was January 6, 1997, more than a month later.  At that time, the
appellant requested a one-day continuance, citing, among other things, the fact that the State was
subjecting  additional blood stains from the night shirt to DNA testing.  The trial court denied the
continuance.  A second Gene Screen report was issued the next day, January 7, 1997, reflecting that
at least six additional blood stains were analyzed.  The appellant never renewed her request for a
continuance.  Moreover, well in advance of trial, before the State conducted any DNA testing of the
night shirt, the appellant was allowed to take cuttings of her own choosing from the night shirt for
whatever forensic analysis she deemed appropriate.  To date, the record does not reveal the results
of any testing the appellant may have conducted.
47. 	 Dr. Johnson opines that "perpetrators often cut themselves during the act of stabbing their
victims."  There is no independent evidence from the trial record to indicate that an unknown
intruder may have cut himself.  For example, investigators found no blood trail leaving the house
that might have suggested a fleeing and wounded intruder.
48. 	 Article 64.01(b)(1)(A)(i).
49. 	 Article 64.01(b)(1)(A)(ii).
50. 	 Though the appellant's original trial attorneys obtained their cuttings from the night shirt
prior to trial, see note 46, ante, she makes no allegation that she was denied the opportunity to
subject those samples to DNA testing herself to look for the DNA of the unknown intruder.
51. 	 As with the pubic hair, the record does not reveal exactly where in the house the facial hair
came from.  The Gene Screen DNA analyst testified that she believed it was recovered from a rug,
but could not say where the rug had been in the house.
52. 	 Article 64.01(b)(2).
53. 	 Thus, she seems to invoke Article 64.01(b)(1)(B).
54. 	 When she had fallen asleep on the couch, the appellant was wearing panties.  As she was
being loaded into the ambulance to go to the hospital, she was no longer wearing them, and they
were never recovered.  She also testified to a vague recollection of feeling "pressure" on her right
leg as she was waking up.  She told one of the nurses that she had felt "a pressure down there."
55. 	 A police officer during a pretrial hearing testified that a rape kit was done.  But, as even the
appellant acknowledged in a letter brief to the convicting court dated June 30, 2006, that police
officer "now recalls that a rape kit was discussed but never performed."

76. 	 This does not amount, of course, to a finding that if the DNA testing turns out as the
appellant hopes, it would conclusively establish her innocence.  Thus, the appellant would not likely
have been able to obtain any DNA testing at all under Kutzner v. State, 75 S.W.3d 427 (Tex. Crim.
App. 2002).  But as we recognized in Smith v. State, supra, that is not the standard after the 2003
amendment to Article 64.03(a)(2)(A).  This means, paradoxically, that even if the DNA testing to
which the appellant is entitled under the statute does in fact provide evidence to corroborate her story
of an unknown intruder, she may not be entitled to relief by way of habeas corpus because she may
well fall short of meeting the onerous standard for proving actual innocence.  See Ex parte Elizondo,
947 S.W.2d 202, 209 (Tex. Crim. App. 1996) (in order to obtain relief on an actual innocence claim
in post-conviction habeas corpus context, applicant must show by clear and convincing evidence that
no reasonable juror would have convicted him in light of new evidence of innocence).  But that does
not render the DNA testing useless to her.  She may still present such evidence to the executive
branch of state government in the form of a clemency petition.
