                                          State of Nebraska, appellee, v.
                                        Christopher A. Edwards, appellant.
                                                     ___ N.W.2d ___

                                            Filed July 1, 2016.   No. S-15-139.

                1.	 Pleadings: Appeal and Error. An appellate court reviews a refusal to
                    grant leave to amend for abuse of discretion.
                2.	 Postconviction: Proof: Appeal and Error. A defendant requesting
                    postconviction relief must establish the basis for such relief, and the
                    factual findings of the district court will not be disturbed unless they are
                    clearly erroneous.
                3.	 Effectiveness of Counsel: Appeal and Error. Appellate review of a
                    claim of ineffective assistance of counsel is a mixed question of law and
                    fact. When reviewing a claim of ineffective assistance of counsel, an
                    appellate court reviews the factual findings of the lower court for clear
                    error. With regard to the questions of counsel’s performance or prejudice
                    to the defendant as part of the two-pronged test articulated in Strickland
                    v. Washington, 466 U.S. 668, 104 S. Ct. 2052, 80 L. Ed. 2d 674 (1984),
                    an appellate court reviews such legal determinations independently of
                    the lower court’s decision.
                4.	 Judges: Words and Phrases. A judicial abuse of discretion exists when
                    the reasons or rulings of a trial judge are clearly untenable, unfairly
                    depriving a litigant of a substantial right and denying just results in mat-
                    ters submitted for disposition.
                5.	 Criminal Law: Words and Phrases. Modus operandi is a character-
                    istic method employed by a defendant in the performance of repeated
                    criminal acts, and means, literally, “method of working,” and refers to
                    a pattern of criminal behavior so distinctive that separate crimes are
                    recognizable as the handiwork of the same wrongdoer.

                    I. NATURE OF CASE
   In March 2007, a jury convicted Christopher A. Edwards
of the crimes of second degree murder and use of a deadly
weapon to commit a felony in connection with the disap-
pearance of Jessica O’Grady. In this appeal, Edwards main-
tains that some of the evidence presented against him at trial
was fabricated by David Kofoed, a former supervisor of the
Douglas County Crime Scene Investigation Division (CSI)
who was discovered to have fabricated and planted evidence
in two different murder cases.1 Edwards also contends that
his former attorney, Steven Lefler, acted under a conflict
of interest during his trial and during the pendency of his
direct appeal.
                     II. BACKGROUND
   This is Edwards’ third appeal to this court. We affirmed
Edwards’ convictions on direct appeal in State v. Edwards
(Edwards I).2 Edwards then filed a motion for postconvic-
tion relief, which the district court denied without an evi-
dentiary hearing. In his second appeal in State v. Edwards
(Edwards II),3 we affirmed the district court’s order on all
but two of Edwards’ claims. With respect to those claims, we
remanded the cause for an evidentiary hearing on two issues:

      See, State v. Cook, 290 Neb. 381, 860 N.W.2d 408 (2015); State v. Kofoed,

(1) whether Edwards was denied due process by the State’s
knowing use of fabricated evidence to obtain his convictions
and (2) whether Edwards’ trial counsel labored under an actual
conflict of interest. After the remand but before the evidentiary
hearing, Edwards filed in this case a “Motion for Leave to
File Second Verified Motion for Postconviction Relief,” which
motion the district court denied. An evidentiary hearing was
held, and the district court denied Edwards’ motion for post-
conviction relief. Edwards appeals for a third time, challenging
the district court’s refusal to grant leave to amend his original
motion for postconviction relief and the district court’s denial
of postconviction relief.
                          1. Edwards I
   In June 2006, Edwards was charged by information with the
crimes of second degree murder and use of a deadly weapon
to commit a felony in connection with the disappearance of
O’Grady. O’Grady was last seen on May 10, 2006, leaving her
apartment on her way to Edwards’ residence.
   Omaha police interviewed Edwards and obtained permis-
sion to search his bedroom at his aunt’s house. A short sword
was found in the closet, and blood was found on the sword.
Other evidence found in Edwards’ bedroom was set forth in
Edwards I as follows:
         Spattered blood was found on the nightstand, head-
      board, clock radio, and ceiling above the bed. Edwards
      was asked to explain the bloodstains on the headboard
      and clock, and replied that “he had cut his wrist.” A small
      bloodstain was located on the top of the mattress. Edwards
      was asked about the bloodstain and replied that “he had
      intercourse with a girlfriend who was menstruating.” But
      on further investigation, a very large, damp bloodstain
      was found on the underside of the mattress, covering most
      of the bottom side of the mattress. Bloodstains were later
      found on the bedding, a chair in the room, a bookcase,
      and laundry baskets. Luminol, a chemical used to locate
      where blood has been cleaned up, was applied to the
                                      -4-

      walls of the room. The Luminol suggested blood on large
      areas of the south and west walls. Stains that appeared
      to be blood were found on the ceiling, covered up by
      white paint.4
   A search of Edwards’ car and the garage was also conducted:
      A shovel and a pair of garden shears were found in
      Edwards’ vehicle. A bloodstain was found on the handle
      of the garden shears. More bloodstains were found on the
      trunk gasket of the car and on the underside of the trunk
      lid. A black, plastic trash bag was found in the garage next
      to the vehicle. The bag contained two bloodstained towels
      and a receipt from a drugstore in west Omaha. Edwards
      had been videotaped purchasing poster paint, white shoe
      polish, and correction fluid at that drugstore on May 11,
      2006, at 7:41 p.m. The poster paint was chemically identi-
      cal to that found on Edwards’ ceiling.5
   The DNA profiles recovered from the blood on the above
items were all consistent with O’Grady’s DNA profile. The
chances of another unrelated Caucasian person having the same
DNA profile as the DNA profile recovered from those items
differed depending on the item, but the chances ranged from 1
in 15.6 billion to 1 in 26.6 quintillion.6
   Edwards was convicted of both crimes for which he was
charged, and he appealed both convictions, arguing, among
other things, that the evidence was insufficient to prove that
O’Grady had been murdered, because her body had not been
found. We affirmed Edwards’ convictions in Edwards I.
                       2. Edwards II
   In July 2010, Edwards filed a motion for postconviction
relief. We summarized the claims set forth in that motion in
Edwards II:

                   STATE v. EDWARDS
                    Cite as 294 Neb. 1

   Edwards claimed that the State violated his due proc­
ess rights by presenting fabricated evidence during his
trial. Edwards alleged that while investigating O’Grady’s
murder, . . . Kofoed, a supervisor of [CSI], planted blood
evidence to be used against Edwards. Edwards’ allega-
tions and attachments set out a history of Kofoed’s unlaw-
ful conduct during other murder investigations. Edwards
alleged that the State’s introduction of forensic evidence
at his trial that had been falsified by law enforcement
officials constituted outrageous government conduct that
violated his right to due process.
   In addition to his due process claim, Edwards alleged
claims of ineffective assistance of counsel. Edwards was
represented by the same three attorneys at trial and on
appeal. First, he alleged that although his lead attor-
ney, . . . Lefler, should have known that Kofoed was
suspected of planting evidence during the 2006 murder
investigation, Lefler did not investigate this information
or effectively impeach Kofoed at trial. Edwards alleged
that Lefler was ineffective because he was a friend
of Kofoed.
   Edwards also claimed that his trial counsel was inef-
fective in failing to retain a DNA expert to testify at trial.
He alleged that an expert could have testified that the
blood on his mattress came from two contributors—nei-
ther of which was Edwards. He claimed that such testi-
mony would have supported his theory that O’Grady had
experienced a miscarriage, which would have explained
the blood on his mattress. He also claimed that his coun-
sel should have obtained additional DNA testing after
learning that mixed DNA samples had been found. He
alleged that this evidence could have opened the door
to other possible theories about the blood on the mat-
tress. Finally, Edwards alleged that his trial counsel failed
to effectively investigate (1) calls made to O’Grady’s
aunt after O’Grady’s disappearance, concerning the
                                      -6-

      location of O’Grady’s car; (2) whether O’Grady had
      contacted an online travel agency around the time of
      her disappearance; and (3) whether an “‘alternate sus-
      pect’” existed.
         Regarding his direct appeal, Edwards alleged that his
      appellate counsel was ineffective in failing to raise (1)
      the trial court’s denial of his motion to change venue, (2)
      the due process violation related to his claim of falsified
      evidence, and (3) his other claims of his trial counsel’s
      ineffective assistance.7
   In August 2011, the district court sustained the State’s
motion to dismiss Edwards’ motion for postconviction relief
without an evidentiary hearing. Edwards appealed.
   In September 2012, in Edwards II, we concluded that only
two issues raised in Edwards’ motion for postconviction relief
warranted an evidentiary hearing: (1) whether Edwards was
denied due process by the State’s knowing use of fabricated
evidence to obtain his convictions and (2) whether Edwards’
trial counsel labored under an actual conflict of interest. As to
Edwards’ other claims, we determined that the district court
properly denied Edwards postconviction relief.
                    3. Edwards’ Motion for
                        Leave to A mend
   After the remand in Edwards II, but before the evidentiary
hearing on the two claims described above, Edwards filed in
this case his motion for leave to file a second motion for post-
conviction relief. In support of his motion, Edwards attached
a document titled “Second Verified Motion for Postconviction
Relief.” That document set forth five claims: (1) Edwards’
due process rights were violated because his convictions were
based on fabricated evidence; (2) Edwards’ due process rights
were violated because the State failed to disclose material
exculpatory evidence; (3) Edwards’ attorney did not provide

conflict-free representation, as required by the 6th and 14th
Amendments to the U.S. Constitution; (4) the step instruction
on the lesser-included offense of manslaughter failed to distin-
guish between the intent to kill associated with second degree
murder and the intent to kill resulting from a “sudden quarrel”;
and (5) cumulative error deprived Edwards of his right to sub-
stantive due process under the 14th Amendment.
   The district court implicitly construed Edwards’ motion for
leave to file a second motion as a motion for leave to amend
his original postconviction motion. The court overruled the
motion to amend, reasoning that it was without power to affect
the rights and duties outside the scope of this court’s remand
in Edwards II. Edwards accepts the court’s characterization
of his motion (as a motion to amend) but appeals the court’s
decision overruling the motion, arguing that he should have
been allowed to amend. Because both Edwards and the district
court treat Edwards’ motion as a motion to amend, and because
Edwards filed the motion for leave to file a second motion
under the same docket number as the original postconvic-
tion motion, we will also treat Edwards’ motion as a motion
to amend.
                     4. Evidentiary Hearing
                           on R emand
   The evidentiary hearing took place on July 8 and August
14, 2013, and March 13, 14, and April 9, 2014. Below, we
set forth the evidence presented at the hearing as it relates to
the issues the district court was to address on remand, i.e.,
(1) whether Edwards was denied due process by the State’s
knowing use of fabricated evidence to obtain his convictions
and (2) whether Edwards’ trial counsel labored under an actual
conflict of interest. The evidence on these two issues includes
not only the testimony presented at the evidentiary hearing, but
also deposition testimony and testimony presented at Edwards’
original trial, as well as exhibits from both the trial and the
postconviction proceedings.

                   (a) Fabrication of Evidence
   For the State to knowingly use fabricated evidence, it is axi-
omatic that there must first be fabricated evidence. Therefore,
before considering any evidence that the State knowingly used
fabricated evidence, we first consider the facts relevant to
Edwards’ claim that Kofoed fabricated evidence against him.
   One of Edwards’ arguments is that the similarities between
the O’Grady investigation and the investigations in which
Kofoed was found to have fabricated evidence show that Kofoed
fabricated evidence in the O’Grady investigation. Accordingly,
we review the facts of those investigations in which Kofoed
was found to have fabricated evidence, specifically, the inves-
tigation into the murders of Wayne and Sharmon Stock and the
investigation into the disappearance and presumed murder of
a 4-year-old child.8 We then review the evidence surrounding
the investigation in this case.

                      (i) Investigation Into
                         Stocks’ Murders
   In April 2006, the Stocks were found murdered in their rural
home outside Murdock, Nebraska. CSI processed the crime
scene. After witnesses reported a tan sedan parked 1 mile from
the Stocks’ home within hours of the murder, law enforcement
followed up on any family member, friend, or associate of the
Stocks who might have owned a similar vehicle. Family mem-
bers identified William Sampson, Sharmon Stock’s nephew, as
a person owning a tan Ford vehicle.
   After a thorough search of Sampson’s vehicle, investigators
failed to find any evidence of blood or other forensic evidence.
The vehicle was moved to CSI’s impound lot.
   One week after the murders, law enforcement obtained a
false confession from another family member, Matthew Livers.
After over 10 hours of questioning, Livers claimed that he
committed the murders, that he used Sampson’s vehicle, and

                               Cite as 294 Neb. 1

that his cousin was also involved. Livers recanted his statement
the next day.
   After Kofoed learned of Livers’ confession, Kofoed and
another investigator, Clelland Retelsdorf, reexamined Sampson’s
vehicle. While Retelsdorf was searching the back seat, Kofoed
claimed to have collected a positive presumptive test for blood
from the front area of the vehicle. Retelsdorf then attempted
to collect four or five samples with a cotton swab in that area,
but the results were negative for blood. Retelsdorf and Kofoed
decided that each would write a report stating what he did, not
what the other investigator did. Retelsdorf completed his report
that day; it did not reflect that Kofoed was present during the
search. Kofoed’s report was not completed until 11 days after
the search. Kofoed’s report reflected that Kofoed had obtained
a filter paper swab on the day the report was filled out, rather
than 11 days prior; it did not reflect that Retelsdorf swabbed
the same area with negative results.
   Kofoed’s filter paper swab was taken to the University of
Nebraska Medical Center’s DNA laboratory (UNMC), and the
blood was matched to the DNA profile of Wayne Stock. This
evidence corroborated Livers’ false confession. One month
later, Livers and his cousin were exonerated; a couple from
Wisconsin confessed to murdering the Stocks.9 The charges
against Livers and his cousin were eventually dismissed.
   In 2010, Kofoed was convicted of tampering with evi-
dence during the Stocks’ investigation.10 At the time of Wayne
Stock’s autopsy, CSI had taken possession of a bloody shirt
worn at the time of the murder. It was placed in a bag, sealed,
and stored in CSI’s biohazard room. The Federal Bureau of
Investigation (FBI) later found that the bag containing the
shirt had been unsealed, then resealed with Kofoed’s initials
on the tape.

              (ii) Investigation Into Disappearance
                     and Presumed Murder of
                         Brendan Gonzalez
   Four-year-old Brendan Gonzalez (Brendan) was reported
missing in January 2003. As part of the investigation, CSI
was called to process a suspected crime scene—the garage of
Brendan’s home. Kofoed and Retelsdorf went to the scene.
They found several droplets of blood on the floor of the garage
and on Brendan’s bike and a recliner rocker located in the
garage. Most, but not all, of the items suspected of containing
biological evidence were submitted to UNMC. The items sub-
mitted for DNA testing showed that the blood on several of the
items were consistent with the DNA profile of Brendan. Other
samples were mixed.
   Despite an extensive search, law enforcement officers
were unable to locate Brendan’s body. But on June 2, 2003,
Brendan’s father confessed that he killed Brendan and dis-
posed of the body in a Dumpster in Bellevue, Nebraska.
Kofoed and Retelsdorf then searched the Dumpster. They
collected swabs from the Dumpster and reported a positive
presumptive test for blood. They also collected some debris
from the Dumpster.
   On June 5, 2003, Kofoed filled out a property report list-
ing the items that he and Retelsdorf had collected from the
Dumpster. The report reflected that Kofoed had swabbed one
of the items with filter paper. All of the items, except the item
Kofoed swabbed, were submitted for DNA testing. However,
those items were never tested for DNA, because the prelimi-
nary screening tests at UNMC were all negative for blood. But
Kofoed’s filter paper swab and the cotton swabs collected from
the Dumpster were tested. The cotton swabs from the Dumpster
were badly degraded, with barely reportable alleles. However,
Kofoed’s filter paper swabs produced a complete DNA profile
without any evidence of degradation or contamination. The
results were consistent with Brendan’s DNA profile, corrobo-
rating his father’s confession.

   The FBI later suspected Kofoed of fabricating evidence in
that case. In the FBI’s own laboratory, it tested the item that
Kofoed claimed to have swabbed and never submitted for DNA
testing. It also sent the item to a private laboratory. No analyst
from either laboratory found any DNA material. At Kofoed’s
criminal trial, experts testified that it was practically impos-
sible to have collected Brendan’s complete DNA profile from
the Dumpster under the environmental factors that were pres-
ent, i.e., exposure to heat and humidity for 21 weeks (approxi-
mately 5 months).
   The issue of whether Kofoed planted evidence in Brendan’s
murder investigation was the subject of an extensive rule
40411 hearing in State v. Kofoed.12 The district court found
that the State had proved by clear and convincing evidence
that Kofoed had fabricated evidence in that investigation. We
affirmed that finding in Kofoed.
                       (iii) O’Grady Investigation
   We turn now to the O’Grady investigation. Because Edwards
claims that Kofoed fabricated blood evidence on the shovel,
garden shears, trunk gasket, and trunk roof, all of which were
located in Edwards’ car, we focus on the search of Edwards’
car. Edwards also claims that the blood evidence on the sword
was fabricated, so we review the discovery and the processing
of the sword as well.
                   a. Search of Edwards’ Car
   For the evidence collected from Edwards’ car, Kofoed served
as the State’s primary foundational witness at Edwards’ trial in
March 2007. He testified that Edwards’ car was to be searched
twice. Joshua Connelly, a forensic scientist for the Douglas
County sheriff’s office, was to perform the first search, and
then William Kaufhold, another CSI investigator, was to do a
second, more detailed search later.

   Kofoed testified that he had a chance to look at the vehicle
before it was transported to the “sally port” where Connelly
performed his search. Kofoed testified that he documented the
contents, that the processing of the vehicle was photographed,
and that the photographs “fairly and accurately depicted
as [he] recalled them to be at the time that [he] observed
that vehicle and processed that vehicle.” Those photographs
included photographs of the front and back seats of Edwards’
car, a photograph of the garden shears removed from the car,
and a photograph of the trunk.
   Connelly and Kaufhold provided deposition testimony in
lieu of testifying at the evidentiary hearing. Connelly confirmed
that he conducted a preliminary search on May 17, 2006, and
testified that he conducted the search by himself. Kaufhold
testified that he and Kofoed conducted a search of the trunk
area of the car on May 18, in which blood evidence was found
on the trunk gasket and metal piece of the roof of the trunk.
Kaufhold also testified that he conducted a third search of the
car involving only the interior on May 19. Kaufhold testified
that he conducted the third search by himself.

                  i. Connelly’s Preliminary Search
   Connelly testified that he was called around midnight on
May 17, 2006, and was told that his services were needed at
the Edwards’ residence. Sometime after Connelly arrived at
the scene, Edwards’ car was transported from the garage of the
residence to a sally port for examination. Connelly went to the
sally port and took photographs of the exterior and interior of
the car.
   Connelly testified that he believed he was the first person to
examine Edwards’ car; however, Edwards argues that Christine
Gabig’s testimony and her photographs suggest otherwise.
Gabig, another forensic scientist for the Douglas County sher-
iff’s office, testified that she was the first CSI investigator who
was called about the O’Grady investigation. When she showed
up at the scene, Omaha Police Department detectives were

already at work. Gabig took a series of photographs of the
scene, separate from Connelly’s photographs of the car. One
of Gabig’s photographs showed the open trunk of Edwards’
car while it was parked in the garage. Gabig testified that she
did not open the trunk and that she did not know who did; it
was open when she began documenting the scene. Another of
Gabig’s photographs showed a shovel leaning against a pole
or pillar in the garage. Gabig stated that she had no personal
knowledge of where the shovel had been before it appeared in
the photograph, but that she was told that Omaha police detec-
tives had removed it from Edwards’ car.
   Connelly had also taken a photograph of the shovel. The
photograph showed the shovel in the back seat of the car with
a paper bag over the “business end.” Connelly testified that
when the shovel was first observed, it was not in the car and
did not have a paper bag over it. He stated that the shovel had
been propped up against a pillar inside the garage and that
someone had put a bag over it and put it in the back of the
car. When asked if he had seen any red stains on the shovel,
Connelly testified that he could not recall. He testified that
if he would have seen any red stains, he would have docu-
mented them, but Connelly did not document any stains on
the shovel.
   Gabig later examined the shovel, but did not report seeing
any blood evidence. At Edwards’ trial, Kofoed testified that
he transported a swab of the shovel, which was collected by
another CSI investigator at Kofoed’s direction, to UNMC on
May 30, 2006. The item tested positive for DNA and was con-
sistent with that of O’Grady’s.
   In addition to the passenger compartment of the car,
Connelly also searched the trunk. He documented how the
trunk appeared when he first opened the lid. He then began to
remove items in “layers,” documenting the scene before and
after he removed each item. When Connelly came across the
garden shears, he photographed them and bagged them sepa-
rately from other evidence.

   One handle of the garden shears had a red mark on it, and
Connelly documented the red mark in a photograph. Connelly
testified that he did not attempt to swab the garden shears or
determine whether the red mark was blood, because he thought
it would be better to send the entire item to UNMC rather than
consume the small sample by conducting a presumptive test.
Kofoed took the garden shears to UNMC for DNA testing on
May 22, 2006. The garden shears tested positive for DNA and
were consistent with that of O’Grady’s.
   When Connelly was asked if he recalled finding any blood
evidence at any point during his search, Connelly stated that he
did not find any blood, but that he could not recall if he was
specifically looking for blood. His task was “to document the
vehicle, document the contents of the vehicle, and collect any-
thing that could be of evidentiary value. It wasn’t to look for
trace evidence. It wasn’t to look specifically for blood.”

                   ii. Kaufhold and Kofoed’s
                         Search of Trunk
   The next day, May 18, 2006, Kaufhold and Kofoed con-
ducted the second search of the car. Kaufhold’s report reflects
that Kofoed advised him to concentrate on the trunk and rear
exterior of Edwards’ car. This search led to the discovery of
bloodstains on the roof of the trunk and on the rubber gasket.
A portion of the roof was then cut out of the car with a jigsaw,
and the rubber gasket was removed. Kaufhold testified that he
was the first to report finding what appeared to be a potential
bloodstain in the trunk and that the first discovery was on
the gasket. Kofoed transported the gasket and metal plate to
UNMC for testing. Both items tested positive for DNA and
were consistent with that of O’Grady’s.

                         b. Sword
  Investigators found swords and knives in Edwards’ closet.
Those items were stored in CSI’s biohazard room from May
17 to 31, 2006. On May 31, Kofoed directed Gabig to process

                        Cite as 294 Neb. 1

the swords and knives for any blood or trace evidence. Gabig
testified that the tip of one of the swords produced a positive
presumptive blood test. However, the presumptive test done
on the sheath of the sword came back negative. A deputy
then transported the sword to UNMC for DNA testing. The
sword tested positive for DNA and was consistent with that
of O’Grady’s.
   The district court found that there was “little to no evi-
dence” Kofoed fabricated any evidence in this case and that
even assuming arguendo that there existed some possibility
that some of the evidence was fabricated, Edwards failed
to offer any evidence that the State knowingly used fabri-
cated evidence.
                   (b) State’s Knowing Use of
                       Fabricated Evidence
   Although there were at least three prosecutors involved
in Edwards’ trial, Edwards chose to present the testimony
of only one at the evidentiary hearing, who testified that he
did not suspect Kofoed of fabricating evidence in Edwards’
case and was not aware at the time of Edwards’ trial that
Kofoed was suspected of fabricating evidence in the Stock
case. Edwards did not offer any evidence to rebut the prosecu-
tor’s testimony. The district court found that Edwards did not
establish that the State knowingly used false evidence to secure
Edwards’ convictions.
   On appeal, Edwards argues that he was not required to
prove that the prosecutor knew about Kofoed’s fabricating
evidence, because the prosecutor is not the only agent of
the State. Instead, Edwards asserts that it was sufficient that
he proved Kofoed, acting as a state agent, fabricated blood
evidence and provided the foundation for that evidence as a
witness at Edwards’ trial. In support of his argument, Edwards
cites Edwards II, wherein we stated, “At an evidentiary hear-
ing, it is Edwards’ burden to establish that state officers
involved in the investigation or prosecution knowingly used

                               Cite as 294 Neb. 1

false evidence to secure his conviction[s].”13 Relevant to this
appeal, Edwards claims that Kofoed fabricated the blood evi-
dence on the items recovered during the search of Edwards’
car: the shovel, garden shears, trunk gasket, and trunk roof.
Edwards also claims that Kofoed planted blood evidence
on the sword while it was stored in CSI’s biohazard room.
Edwards does not claim and has never claimed that Kofoed
fabricated any of the evidence collected from his bedroom,
with the exception of the sword.

                       (c) Conflict of Interest
   We turn now to the evidence relevant to the issue of whether
Edwards’ trial counsel operated under a conflict of interest.
Although we do not consider whether Edwards’ appellate
counsel labored under a conflict of interest, we recite the facts
surrounding Lefler’s subsequent representation of Kofoed,
because it could be argued that such facts are relevant to the
determination of whether Lefler had a conflict of interest at the
time of trial.
   In Edwards II, we explained Edwards’ allegations concern-
ing the purported conflict of interest as they were set forth in
Edwards’ original postconviction motion, as well as some of
the evidence supporting those allegations:
         Edwards alleged that by September 2006, it was clear
      that Kofoed had planted blood evidence while investigat-
      ing the Stocks’ murders. He alleged that a reasonably
      diligent defense attorney would have known Kofoed was
      suspected of planting evidence while investigating the
      Stocks’ murders. And he alleged that Lefler knew of these
      allegations because of his friendship with Kofoed. He
      claimed that Lefler repeatedly cited his friendship with
      Kofoed during his representation of Kofoed in the federal
      and state trials.

                                Cite as 294 Neb. 1

        In fact, this record supports Edwards’ contention that
     Lefler had a personal relationship with Kofoed. Before
     trial, Edwards moved to exclude Kofoed’s testimony
     because of his televised demonstration of blood splatters.
     In arguing for the motion, Lefler referred to his friendship
     with Kofoed:
     “I’m going to ask the Court to prevent Dave Kofoed,
     who’s a friend of mine and I like him a ton . . . I’m going
     to ask you to prevent him from testifying in this particu-
     lar case as a consequence of the TV demonstration that
     he gave. . . .
        ....
        “. . . [W]hat we are worried about for . . . Edwards is
     that there’s going to be some juror who halfway through
     the trial is going to remember seeing this TV clip.
        “And Dave Kofoed’s a great—a nice man, smart guy.
     And so I’m just worried that halfway through the trial it
     clicks in some juror’s mind.”14
   Other evidence in support of Edwards’ contention included
statements made by Lefler to Kofoed in a deposition which
took place in October 2006, prior to Edwards’ trial, including:
        Dave, I always feel awkward interviewing you, cross-
     examining you, because we’ve become friends. I’ve used
     you, I’m a special prosecutor, but we both have a job to
     do and I’m sure you understand that.
        ....
        . . . And I’m embarrassed to ask this question because
     we are friends, but this is a murder investigation: Have
     you before been reprimanded by either the [Omaha Police
     Department] or the sheriff’s department while you’ve
     been in their employ?”
   Sometime after the remand, Edwards learned that Lefler
began to represent Kofoed in June 2008 while still represent-
ing Edwards on direct appeal. Although the district court

refused to consider whether Edwards’ appellate counsel labored
under a conflict of interest in its order denying postconviction
relief, it allowed Edwards to “make his record” at the eviden-
tiary hearing.
   Lefler was the only witness called at the evidentiary hearing
to testify about the alleged conflict of interest. Lefler testified
that at the time of Edwards’ trial, he knew who Kofoed was,
but adamantly denied any friendship with him. Lefler knew of
Kofoed because Kofoed, had testified in a few cases in which
Lefler had represented other individuals. Kofoed had also testi-
fied for Lefler in a case where Lefler served as a special pros-
ecutor. But Lefler explained that he and Kofoed never went out
for dinner or drinks together or did any other kind of “friend-
related activity.”
   As for Lefler’s statements during Kofoed’s deposition and
during the trial that tended to indicate a friendship between
Lefler and Kofoed, Lefler explained that this was a trial strat-
egy that he had used throughout his career with witnesses other
than Kofoed. He explained:
      [I]f I’m nice to a cop, the cop’s going to tell me some-
      thing he or she might not ordinarily tell me, and that’s a
      benefit to my client. And so what I should have said, you
      know, now that I have been — now that my feet has [sic]
      been held to the fire, the Supreme Court saying that I was
      a jerk because I was friends with Dave Kofoed, I should
      have said at that time he was a professional acquaintance
      of mine.
   Lefler also adamantly denied having any knowledge of oth-
ers’ suspicions that Kofoed was planting evidence at the time
he filed Edwards’ direct appeal or any time prior. He testi-
fied that he did not learn of the allegations against Kofoed
until June 2008, when Kofoed called him and requested a
visit. Lefler testified that at that time, he had “no clue” why
Kofoed called him or wanted to meet. When they met, Kofoed
informed Lefler that the FBI had interviewed him about
the Stocks’ murder investigation and that an agent had told

Kofoed that his story did not “‘smell right.’” Lefler agreed to
represent Kofoed a couple of days later.
   Lefler testified that before he agreed to represent Kofoed, he
considered whether that representation would cause a conflict
of interest. Lefler testified that he researched the issue and even
reached out to the Nebraska State Bar Association. A member
of the Counsel for Discipline advised him that “‘the film’s
in the can,’” meaning that Lefler’s representation of Kofoed
would not affect Edwards’ case, even though there were still
briefs to be written for Edwards on direct appeal. Lefler also
explained that it was mainly his cocounsel who wrote the briefs
and that she was the one who argued before this court.
   After the evidentiary hearing, the district court determined
that Edwards’ trial counsel did not operate under a conflict of
interest and, therefore, rejected his ineffective assistance of
counsel claim.
               III. ASSIGNMENTS OF ERROR
   Edwards assigns, combined and restated, that the district
court erred in (1) refusing to grant leave to amend his original
postconviction motion; (2) failing to find that Edwards’ coun-
sel had an actual conflict of interest, in violation of the 6th and
14th Amendments to the U.S. Constitution; and (3) failing to
find that the State knowingly used fabricated evidence, in vio-
lation of Edwards’ due process rights.
                IV. STANDARD OF REVIEW
   [1] An appellate court reviews a refusal to grant leave to
amend for abuse of discretion.15
   [2] A defendant requesting postconviction relief must
establish the basis for such relief, and the factual findings
of the district court will not be disturbed unless they are
clearly erroneous.16

   [3] Appellate review of a claim of ineffective assistance of
counsel is a mixed question of law and fact. When review-
ing a claim of ineffective assistance of counsel, an appellate
court reviews the factual findings of the lower court for clear
error. With regard to the questions of counsel’s performance
or prejudice to the defendant as part of the two-pronged test
articulated in Strickland v. Washington,17 an appellate court
reviews such legal determinations independently of the lower
court’s decision.18
                         V. ANALYSIS
   [4] The first issue is whether the district court abused its
discretion in overruling Edwards’ motion to amend his original
postconviction motion. An appellate court reviews a refusal to
grant leave to amend for abuse of discretion.19 A judicial abuse
of discretion exists when the reasons or rulings of a trial judge
are clearly untenable, unfairly depriving a litigant of a sub-
stantial right and denying just results in matters submitted for
disposition.20 We need not consider whether the district court’s
reason for denying the motion for leave to amend here was
tenable, because we conclude that the ruling did not deprive
Edwards of a substantial right or just result and, therefore,
could not have been an abuse of discretion.
   We must assume that the substantial right that Edwards
claims is his right—if such right exists—to be heard on
his “new” claims. But assuming that right exists (i.e., that
Edwards did not waive those claims by failing to assert them

in a prior appeal in which he had a motive and opportunity
to do so21), the district court’s ruling would not have deprived
Edwards of that right. At the time of filing his motion
to amend the postconviction proceeding, assuming without
deciding that Edwards was not procedurally or time barred,
Edwards could have filed a second postconviction proceed-
ing alleging the claims he attempted to raise on remand. We
have held that a subsequent postconviction motion is allowed
when the motion affirmatively shows on its face that the
basis relied upon for relief was not available at the time of
the filing of the prior motion.22 Edwards asserts that such is
the case here. Accordingly, we conclude that Edwards could
have filed a second postconviction proceeding asserting the
claims that he alleged he was unable to raise in the first post-
conviction proceeding. Therefore, the district court did not
deprive Edwards of a substantial right or just result and did
not abuse its discretion by denying his motion to amend his
first postconviction claim. Edwards’ first assignment of error
is without merit.
   The second issue is whether the district court erred in deter-
mining that Edwards’ trial counsel did not operate under an
actual conflict of interest. In Edwards II, we set forth the rel-
evant rules for resolving this claim:
         The right to effective assistance of counsel entitles the
      accused to his or her counsel’s undivided loyalties, free
      from conflicting interests. But a defendant who raised
      no objection at trial must show that an actual conflict of
      interest existed and that the conflict adversely affected
      his lawyer’s performance. If the defendant satisfies this
      requirement, the defendant is not required to show that
      the Sixth Amendment violation had a probable effect on
      the outcome of the trial to obtain relief.

         In 2002, in Mickens v. Taylor, [535 U.S. 162, 172 n.5,
      122 S. Ct. 1237, 152 L. Ed. Ed. 2d 291 (2002),] the U.S.
      Supreme Court stated that the “actual conflict” inquiry
      is not separate from a performance inquiry: “An ‘actual
      conflict,’ for Sixth Amendment purposes, is a conflict of
      interest that adversely affects counsel’s performance.”
      Thus, we have stated that when an actual conflict exists,
      there is no need to show that the conflict resulted in
      actual prejudice to the defendant (meaning no need to
      show the outcome of the proceeding was affected). But
      the substantive analysis is the same. If the defendant
      shows that his or her defense counsel faced a situation in
      which conflicting loyalties pointed in opposite directions
      and that his or her counsel acted for the other client’s
      interests and against the defendant’s interests, prejudice
      is presumed.23
   But the district court found that Lefler did not have an actual
conflict of interest at the time he served as Edwards’ trial coun-
sel. It reasoned that “[t]here is no evidence that any relation-
ship existed between Kofoed and Lefler before June, 2008.”
Because there was some evidence of a relationship, we agree
with Edwards that this latter statement by the district court was
an overstatement. However, we find that Edwards failed to
prove by a preponderance of the evidence that his trial counsel
operated under a conflict of interest.
   The record simply does not support a finding that Lefler
had such a loyalty to Kofoed that would have tempted him
at trial to act against Edwards’ interests. Although Lefler’s
statements at the deposition and Edwards’ trial suggested
some sort of relationship between Lefler and Kofoed, Lefler
clarified at the evidentiary hearing that this relationship was
strictly professional. Lefler testified that he and Kofoed never
went out to dinner or out for drinks or any other kind of activ-
ity typically done with friends. No evidence was presented

at the evidentiary hearing to rebut Lefler’s testimony, except
that Edwards offered depositions and trial testimony wherein
Lefler and Kofoed made statements suggesting that they
were “friends,” a term which has lost meaning in the age of
“Facebook” and other social networking sites. Even assum-
ing that Lefler had any loyalty to Kofoed, Edwards fails to
point to any situation during or prior to his trial in which
Lefler acted in Kofoed’s interest and against Edwards’ inter-
est. We therefore conclude that the district court did not err
in finding that Edwards’ trial counsel did not operate under
a conflict of interest. Edwards’ second assignment of error is
without merit.
   The third and final issue in this case concerns whether
the State knowingly used fabricated evidence in violation of
Edwards’ due process rights. Because Edwards had the burden
to prove by a preponderance of the evidence that Kofoed fab-
ricated evidence in his case,24 we interpret the district court’s
statement that there was “little to no evidence that Kofoed
fabricated evidence in this case” as a finding that Kofoed did
not fabricate evidence in this case. The district court also found
that there was no evidence that the State knowingly used false
evidence to secure Edwards’ convictions. We review each of
these factual findings for clear error.25
   The district court did not commit clear error in finding that
Kofoed did not fabricate evidence in Edwards’ case. Edwards
does not offer any direct evidence supporting his allegations,
and the circumstantial evidence is limited. Edwards relies
heavily on the fact that Kofoed has been found to have fab-
ricated evidence in two other investigations—the Stocks’ and
Brendan’s murder investigations. He claims that the simi-
larities between those investigations and the investigation here
show that Kofoed also fabricated evidence here. But contrary

to Edwards’ argument, we interpret the evidence in those
investigations as evidence that Kofoed did not fabricate evi-
dence here.
   [5] We consider Kofoed’s modus operandi. Modus operandi
is a characteristic method used in the performance of repeated
criminal acts.26 “Modus operandi means, literally, ‘method of
working,’ and refers to a pattern of criminal behavior so dis-
tinctive that separate crimes are recognizable as the handiwork
of the same wrongdoer.”27 In the Stocks’ and Brendan’s mur-
der investigations, Kofoed’s modus operandi was not to plant
the victim’s blood on the physical evidence; rather, Kofoed’s
modus operandi had been to swab blood known to be the vic-
tim’s and then submit it for DNA testing, falsely claiming to
have swabbed physical evidence connected to the defendant,
whom Kofoed believed committed the crime. With respect to
the blood evidence on the sword, trunk gasket, and trunk roof,
Kofoed did not claim to take swabs of those items and submit
them to UNMC; instead, those items were taken directly to
UNMC for the DNA analyst to swab. The shovel was swabbed
by another CSI investigator and transported to UNMC by
Kofoed. But there is no evidence that the shovel was later
tested and found to have no DNA evidence on it. Thus, we find
that Edwards’ argument concerning the similarities in the three
investigations is misplaced.
   The only relevance of the Stocks’ and Brendan’s murder
investigations is that they show Kofoed’s propensity to fabri-
cate evidence. But a person’s propensity to commit an act is
insufficient by itself to prove that the person committed the act
in the instant case. In other words, Kofoed may have fabricated
evidence in those cases, but it does not mean he fabricated
evidence here.

   Edwards also suggests that Kofoed’s testimony at the trial
shows that he had the opportunity to plant the evidence. But,
as the district court correctly noted, although Kofoed testified
that he had the chance to look at Edwards’ car before it was
transported to the sally port, there was no evidence that Kofoed
had access to the car without the observation of others. To the
contrary, Gabig testified that when she arrived shortly after
CSI’s team, Omaha police and Douglas County sheriff’s office
personnel were already at work there.
   Besides lack of opportunity, we also note a lack of motive
to fabricate evidence in this case. In the Stocks’ and Brendan’s
murder investigations, there was little more than a confession
connecting the crime to the person that Kofoed believed com-
mitted it. Here, O’Grady’s blood was all over Edwards’ bed-
room. More than half of the bottom of Edwards’ mattress was
covered in O’Grady’s blood. There was blood on the bedding,
headboard, nightstand, and clock radio. There was blood on the
bookcase, laundry baskets, and a chair in the room. There was
also blood on the towels in a trash bag in the garage. Edwards’
explanation as to how the blood happened to be present in
all those places was implausible. With such an overwhelming
amount of evidence, we see no reason for Kofoed to be moti-
vated to fabricate evidence in this case.
   Nevertheless, Edwards suggests to this court that Kofoed
transferred blood from Edwards’ mattress to the sword, shovel,
garden shears, trunk gasket, and trunk roof. Edwards’ theory
rests solely on Connelly’s testimony that this kind of transfer
is hypothetically possible. But there was no evidence that such
transfer was actually done in this case. Edwards notes that the
blood spatter expert who testified at Edwards’ trial was “never
asked whether . . . the sample might have been diluted, or
[about] the period of time the stain had been on the metal plate
before removal.”28 This statement incorrectly assumes that it
is the State’s burden to prove that Kofoed did not fabricate

evidence; to the contrary, it is Edwards’ burden to prove that
he did.29
   We conclude that the district court did not err when it deter-
mined that Kofoed did not fabricate evidence in this case.
   In order for the State to knowingly use fabricated evidence,
there must be fabricated evidence. Because we affirm the dis-
trict court’s finding that Kofoed did not fabricate evidence in
this case, and because there is no evidence that anyone else
fabricated evidence in this case, we conclude that the district
court did not err in finding that Edwards failed to prove that
the State knowingly used fabricated evidence in order to obtain
his convictions.
                        VI. CONCLUSION
   The district court did not deprive Edwards of a substantial
right or just result when it overruled his motion to amend
his original postconviction motion. Edwards could have filed
a second postconviction motion alleging the same claims.
Therefore, the district court did not abuse its discretion in
overruling Edwards’ motion to amend. We also conclude that
the district court did not err in finding that Edwards’ trial
counsel did not operate under a conflict of interest. It did
not err in finding that Kofoed did not fabricate evidence in
this case and that the State did not knowingly use false evi-
dence to obtain Edwards’ convictions. We therefore affirm
the district court’s denial of Edwards’ motion for postconvic-
tion relief.

remand. In my opinion, the district court did not err, because
Nebraska’s postconviction statutes do not allow a prisoner to
amend his or her postconviction motion after the district court
has entered an order denying postconviction relief without an
evidentiary hearing.1
   As the majority opinion notes, in State v. Edwards
(Edwards II),2 we concluded that only two of the many issues
raised in Edwards’ postconviction motion warranted an evi-
dentiary hearing. As to Edwards’ other postconviction claims,
we affirmed the district court’s order denying postconviction
relief. We remanded the cause for an evidentiary hearing on
only two of the postconviction claims. After the mandate was
spread on remand, Edwards sought leave to amend his post-
conviction motion to assert additional grounds for relief. The
district court denied the motion to amend, and Edwards assigns
error to this ruling.
   In State v. Robertson,3 we observed that postconviction
relief under Neb. Rev. Stat. § 29‑3001 (Cum. Supp. 2014)
is a very narrow category of relief,4 subject to specific statu-
tory pleading requirements.5 And we held that nothing in
Nebraska’s postconviction statutes authorizes a prisoner to
amend a postconviction pleading after the court has deter-
mined it is insufficient to warrant an evidentiary hearing.6 We
concluded that Nebraska’s postconviction statutes simply do
not contemplate the opportunity to amend a pleading after the
court determines the pleading is insufficient to necessitate an
evidentiary hearing.7

   Edwards did not seek leave to amend his postconviction
motion until after the court had denied an evidentiary hearing
on his postconviction claims, after he had appealed from that
final order,8 and after the matter had been remanded to the
district court with directions to conduct an evidentiary hear-
ing on only two of the claims. Given that procedural posture,
it was not error for the district court to deny Edwards’ motion
to amend.
