JUSTICE FEW: Billy Phillips was convicted of murder and possession of a weapon
during the commission of a violent crime. At trial, a DNA analyst testified Phillips
could not be excluded as a contributor to a mixture of DNA recovered from two
samples taken from the crime scene. The analyst conceded, however, the statistical
probability that some other randomly selected and unrelated person also could not
be excluded as the person who left the DNA was—for one of the samples—only one
in two. In addition, the State failed to explain to the trial court or the jury three
fundamental concepts underlying the DNA testimony the analyst gave in this
particular case. Finally—in several instances—the State presented information to
the trial court and the jury that was simply wrong. We hold the trial court erred in
not sustaining Phillips' objections to this testimony. We reverse and remand for a
new trial.

      I.     Facts and Procedural History

Darius Woods was a well-known drug dealer in Ridgeland, South Carolina. His
customers knew him to carry large amounts of cash. On the night of May 18, 2013,
two of Woods' customers—Shontay McKeithan and Davonte Freeman—found him
dead in his house. He was lying on his back with his hands above his head. Someone
shot him twice with his own .38 caliber revolver, once in the neck and once in the
head. The shot to the head was a contact wound, meaning the muzzle of the pistol
was in contact with Woods' skin when the pistol was fired. Law enforcement
officers found the pistol on Woods' stomach. His jeans pockets had been pulled out
as though the killer had stolen his money.

At the January 2016 trial, McKeithan testified she arrived at Woods' house around
10:30 p.m. to purchase marijuana. She remained in her car while she called Woods'
cell phone, but Woods never answered. As she waited for Woods to answer, her
cousin Davonte Freeman arrived to purchase marijuana from Woods. She and
Freeman called Woods' cell phone again and could hear it ringing inside, but Woods
did not answer. Freeman then went inside for what McKeithan described as "five to
seven minutes." McKeithan testified she did not hear any gunshots. When Freeman
came back outside, he was holding a gun and screaming that Woods was dead. She
testified he went back inside, and later told her he put the gun where he found it.

Freeman testified he arrived at Woods' house to buy marijuana and saw McKeithan
in her car. He knocked on Woods' door but no one answered, so he went in the house
and found Woods dead on the floor. Woods' gun was on his stomach, and his jeans
pockets were pulled out. Freeman testified he panicked. He picked up the gun,
smelled it to determine if it had been fired, and immediately put the gun back on
Woods' stomach. He testified he was inside less than a minute before he went
outside to tell McKeithan Woods was dead. He denied he ever took the gun outside.
Several witnesses testified they saw Phillips in the general vicinity of Woods' house
within an hour or so before Freeman found the body. Donte Jenkins testified he,
Woods, and Phillips were hanging out at Woods' house on the evening of the murder.
Jenkins left Woods and Phillips alone at Woods' house at approximately 9:15 p.m.
Taylor Cowherd testified she saw Phillips on Woods' porch between 9:25 and 9:31
p.m. Wrenshad Anderson—Freeman's brother—testified he saw Phillips walking to
a nearby BP gas station at approximately 9:40 p.m. Reginald Green testified Phillips
called Green shortly after 10:00 p.m. to ask Green to come pick him up. Green
testified he picked up Phillips at Phillips' brother's house and then drove to the BP
station where Phillips went inside to purchase cigars and beer for himself, and $5
worth of gas for Green. Phillips hung out with Green for a few hours until Green
dropped Phillips off at a house in the same neighborhood as Woods' house. Each of
these witnesses testified to circumstances—in addition to seeing Phillips near
Woods' house—that supported the State's claim that Phillips killed Woods.

In the early hours of the morning after the murder, a Ridgeland Police Department
officer approached Phillips on the street and asked him to come to the police
department to speak with officers about Woods' murder. Two South Carolina Law
Enforcement Division (SLED) agents interviewed Phillips around 3:00 a.m. The
State played a video of this interview for the jury. In the interview, Phillips denied
shooting Woods. Phillips said he visited Woods several times the day of the murder,
and during these visits, he and Woods smoked marijuana and drank alcohol. Phillips
explained he held and pointed Woods' gun to imitate law enforcement officers.
Phillips claimed Woods was alive when Phillips left between 9:30 and 10:00 p.m.,
and he denied being present at the time Woods was murdered. After the interview,
an investigator collected a DNA sample from Phillips.

Six days later, SLED conducted a second interview in which Phillips gave a different
account of what happened. The agent who conducted this interview testified to some
of the things Phillips said, but the State did not play the video of it for the jury. The
agent testified Phillips told him he was sitting in Woods' car when three men
approached Woods' house. One of the men entered the house while the other two
men remained on the porch. Phillips heard gunshots, and as the three men were
leaving, they made eye contact with Phillips. One of the men called Phillips by his
nickname, "Dee." Phillips told the agent that because he was in fear of his life, he
got out of the car and ran to his mother's house. The route there required him to pass
the BP station. Phillips told the agent he gave a different story during his first
interview because he was afraid something would happen to him or his family.
During the State's investigation, SLED collected DNA "standards" from six people
in addition to Phillips. They were Freeman, McKeithan, three officers, and another
person later determined not to be involved. SLED forensic analyst Lilly Gallman
compared the DNA standards to "touch DNA"1 samples collected from the scene of
the crime and during Woods' autopsy. Of the touch DNA samples Gallman
analyzed, she excluded Phillips as a contributor to all of the samples except two.
The first sample—already mentioned—came from Woods' right front jeans pocket.
The second was taken from the grip of Woods' gun.

In a written pre-trial motion, Phillips objected to the admissibility of Gallman's DNA
testimony. The trial court conducted a hearing on the motion before trial, but did
not take testimony. The court ruled Gallman's testimony was admissible. Phillips
renewed his objections when Gallman testified during trial. The jury convicted
Phillips of murder and possession of a weapon during the commission of a violent
crime. The trial court sentenced Phillips to concurrent prison terms of forty years
for murder and five years for the weapon charge. The court of appeals affirmed.
State v. Phillips, Op. No. 2018-UP-081 (S.C. Ct. App. filed Feb. 14, 2018). We
granted Phillips' petition for a writ of certiorari.

      II.    Admission of DNA Expert Testimony

In State v. Council, 335 S.C. 1, 515 S.E.2d 508 (1999)—this Court's first opportunity
to study the admissibility of expert opinion on DNA evidence under our new Rules
of Evidence—we upheld the trial court's decision to admit DNA evidence that (1)
implicated the defendant in a heinous murder and sexual assault and (2) exonerated
the person the defendant blamed for the crimes. 335 S.C. at 17, 515 S.E.2d at 516.
Our focus in Council was on the scientific methodology used by the FBI expert to
analyze the DNA evidence. Concluding that the expert's method—mitochondrial
DNA analysis of pubic hair found at the crime scene—was sufficiently reliable, we
set forth what has become the standard South Carolina formulation of the elements
of the foundation for scientific evidence under Rule 702. "When admitting scientific
evidence under Rule 702," we held, "the trial judge must find the evidence will assist
the trier of fact, the expert witness is qualified, and the underlying science is
reliable." 335 S.C. at 20, 515 S.E.2d at 518. We also held that—"if the evidence is


1
  "Touch DNA" is one of the three fundamental concepts we mentioned in the
introduction to this opinion. As we will explain in detail in Section II.C.—in which
we address all three concepts—touch DNA is taken from skin or other cells left on
a surface after it was touched.
admissible under Rule 702"—the trial court must determine whether the probative
value is substantially outweighed by the dangers listed in Rule 403. Id.

The "assist the trier of fact" element of the Rule 702 foundation was not specifically
litigated in Council, nor was Rule 403. In particular, because the expert testified the
DNA evidence established the other person "could not have been the donor" of the
pubic hair, 335 S.C. at 17, 515 S.E.2d at 516, and "most probably the hair . . .
belonged to [the defendant]," 335 S.C. at 18-19, 515 S.E.2d at 517, there could not
have been any doubt the evidence would "assist the trier of fact." Presumably for
the same reasons, the defendant did not challenge the probative value.

In this case, however, Gallman testified the statistical probability that another
person—not Phillips—could have been the contributor to the touch DNA sample
taken from the gun was one in two hundred, and the probability another person was
the contributor to the jeans pocket sample was one in two. Phillips argues these
probabilities substantially undermine the probative value of Gallman's testimony,
which in turn raises the question of whether Gallman's testimony satisfied the "assist
the trier of fact" element. Phillips also argues Gallman's testimony was unfairly
prejudicial, confusing, and likely to mislead the jury, and these dangers substantially
outweighed the low probative value of her testimony under Rule 403.

             A.     Gallman's Testimony

Gallman analyzed at least thirteen touch DNA samples collected in connection with
Woods' murder: two samples from the grip of the gun; eight samples from Woods'
blue jeans; and three other samples from socks and a piece of jewelry found at the
crime scene. Two of the thirteen samples could not be reliably tested. Of the eleven
remaining touch DNA samples, Gallman compared each one to the standards from
the seven people who submitted DNA for testing. She concluded Phillips' DNA was
not present in nine of the samples. In the words Gallman used to describe this
conclusion to the jury, she "excluded" Phillips as a contributor to the DNA in each
of these nine samples.

As to the other two samples—one from the gun and one from inside Woods' jeans
pocket—Gallman testified each contained a mixture of DNA from at least three
people. She testified Woods and Phillips "cannot be excluded as contributors" to the
mixtures in either sample. The other people who submitted standards for testing—
including Freeman—were excluded, except that one of the officers could not be
excluded as a contributor to the sample from the gun.
Gallman testified DNA experts "are required" to determine the probability of an
error in matching the suspect to a particular DNA sample.2 Gallman then explained
the likelihood it was another person who left his DNA on the gun or in the jeans
pocket. As to the sample from the gun, she testified "the probability of randomly
selecting an unrelated individual who could have contributed to this mixture is
approximately one in two hundred." As to the jeans, she testified the probability
was "one in two." Gallman did not explain how she calculated the probabilities.

             B.    Probative Value

The primary basis for Phillips' objection to Gallman's testimony was Rule 403. We
begin our analysis of a Rule 403 objection with probative value. To understand the
probative value of any evidence, we must consider what was practically in dispute
at trial. State v. Gray, 408 S.C. 601, 610, 759 S.E.2d 160, 165 (Ct. App. 2014).
Woods was clearly murdered; the only significant issue—as a practical matter—was
who murdered him. We must then consider how important the challenged evidence
is to resolving the practically disputed questions. See State v. James, 355 S.C. 25,
35, 583 S.E.2d 745, 750 (2003) (stating "the probative worth of any particular bit of
evidence is obviously affected by the scarcity or abundance of other evidence on the
same point" (quoting Old Chief v. United States, 519 U.S. 172, 185, 117 S. Ct. 644,
652, 136 L. Ed. 2d 574, 590 (1997))); Gray, 408 S.C. at 610, 759 S.E.2d at 165.

In most murder cases, who touched the murder weapon would be extremely
important to the question of who committed the murder. In this case, however,
Phillips admitted he spent several hours at Woods' house that day, and he held
Woods' gun to imitate law enforcement officers. Phillips' own admissions placed
him at the scene of the crime, holding the gun. Thus, the probative value of
Gallman's testimony connecting Phillips to the DNA on the gun is minimal.



2
  Gallman testified, "We are required to tell you how often you would see this
mixture in a population." Academic sources are more precise. See, e.g., National
Research Council, DNA TECHNOLOGY IN FORENSIC SCIENCE 9 (1992) ("Interpreting
a DNA typing analysis requires a valid scientific method for estimating the
probability that a random person by chance matches the forensic sample at the sites
of DNA variation examined. To say that two patterns match, without providing any
scientifically valid estimate . . . of the frequency with which such matches might
occur by chance, is meaningless.").
Evidence that Phillips had his hand in Woods' pocket, on the other hand, could have
far more probative value. The State's theory of the case was that Phillips was mad
at Woods for tricking him out of a PlayStation, and Phillips murdered and robbed
Woods in retaliation, knowing Woods carried a lot of cash. DNA evidence placing
Phillips' hand inside Woods' jeans pocket—where he presumably kept his cash—
would be pivotal to the State's ability to convince the jury its theory was correct, and
thus prove the primary disputed fact: who murdered Woods. Contrary to the
evidence Phillips handled Woods' gun, there is no known "innocent" reason for
Phillips to have his hand in Woods' pocket. At first glance, therefore, the probative
value of the evidence appears high.

This brings us to the heart of Phillips' objection. While evidence Phillips had his
hand in Woods' pocket could be important to the State in proving its theory of the
case, Gallman did not testify the DNA evidence showed Phillips had his hand in
Woods' pocket. Rather, Gallman testified her analysis of the touch DNA sample
from Woods' pocket revealed a mixture of DNA from at least three people.
Importantly, Gallman did not testify Phillips was one of those people. In her words,
"Phillips cannot be excluded as [a] contributor[] to this mixture." She testified that
one in two people—half of the population—could have been the person who left the
DNA in Woods' pocket. In other words, even if Gallman's testimony were clear and
readily understood, the best she could do with her DNA analysis was to narrow the
identity of the person who had his hand in Woods' pocket—the murderer according
to the State's theory—to half of the population. The probative value of Gallman's
testimony connecting Phillips to the DNA in Woods' jeans pocket is minimal.

             C.     Unfair Prejudice, Confusion, Misleading the Jury

The minimal probative value of Gallman's testimony must be balanced against "the
danger of unfair prejudice, confusion of the issues, or misleading the jury." Rule
403, SCRE. Phillips argues all three are applicable here.

Most of our Rule 403 cases involve only unfair prejudice. Unfair prejudice is the
tendency of the evidence to suggest a decision based on something other than the
legitimate probative force of the evidence. Gray, 408 S.C. at 616, 759 S.E.2d at 168.
Phillips argues Gallman's DNA testimony was unfairly prejudicial because it
confused and misled the jury. However, Phillips offers no legal authority to support
his argument that confusion of issues or misleading the jury can itself be unfair
prejudice.3 We believe the danger of unfair prejudice is a separate analysis from the
danger of confusion of the issues or misleading the jury.

We turn, therefore, to the danger that Gallman's testimony would confuse the issues
or mislead the jury. DNA evidence is well known as a powerful and accurate
evidentiary tool for the State to solve crimes and obtain convictions. Nevertheless,
DNA evidence has also come to be known for its potential to confuse and mislead
jurors. This potential has been widely discussed by courts and in academic writing.
In United States v. Bonds, 12 F.3d 540 (6th Cir. 1993), for example, the Sixth Circuit
recognized, "The aura of reliability surrounding DNA evidence does present the
prospect of a decision based on the perceived infallibility of such evidence . . . ." 12
F.3d at 567-68. More recently, the New York Court of Appeals recognized, "The
persuasiveness of DNA evidence is so great that as one commentator noted, 'when
DNA evidence is introduced against an accused at trial, the prosecutor's case can
take on an aura of invincibility.'" People v. Wright, 37 N.E.3d 1127, 1137 (N.Y.
2015) (quoting Robert Aronson & Jacqueline McMurtrie, The Use and Misuse of
High-Tech Evidence by Prosecutors: Ethical and Evidentiary Issues, 76 Fordham L.
Rev. 1453, 1469 (2007)). The Wright court also stated "the potential danger posed
to defendant when DNA evidence is presented as dispositive of guilt is by now
obvious." Id. The Maryland Court of Appeals wrote "jurors place a great deal of
trust in the accuracy and reliability of DNA evidence. But this evidence has the
potential to be highly technical and confusing in a way that could unduly affect the
outcome of a trial." Whack v. State, 73 A.3d 186, 188 (Md. 2013).4

3
 But see 29 Am. Jur. 2d Evidence § 326 (2019) ("Unfair prejudice may arise from
evidence that . . . confuses or misleads the trier of fact . . . ." (citing State v. Franks,
335 P.3d 725, 729 (Mont. 2014))).
4
 In 2008, the American Psychological Association published an article summarizing
the results of three studies concerning the impact of DNA evidence on jurors. Joel
D. Lieberman et al., Gold Versus Platinum: Do Jurors Recognize the Superiority
and Limitations of DNA Evidence Compared to Other Types of Forensic Evidence?,
14 Psychol. Pub. Pol'y & L. 27 (2008). Researchers found, "Public jurors, on
average, rated DNA evidence as 95% accurate, and it was rated as 94% persuasive
of a suspect's guilt." Id. at 52-53. Researchers also found DNA evidence was viewed
by the public as more accurate than other evidence, including eyewitness testimony
and suspect confessions. Id. at 37. The article warned, "The strong and largely
invariant impact of DNA evidence across experimental conditions suggests that this
type of scientific evidence may be so persuasive that its mere introduction in a
criminal case is sufficient to seriously impede defense challenges." Id. at 58; see
In most cases, the risk of confusing or misleading the jury with DNA evidence is
low because—in most cases—the DNA evidence is straightforward and reliable, and
its legitimate probative force is highly persuasive—if not dispositive—of guilt. In
Council, for example, the DNA expert performed mitochondrial DNA analysis on
pubic hair found at the crime scene. He testified the hair "most probably" belonged
to the defendant, and the hair certainly did not belong to the person the defendant
blamed. 335 S.C. at 18-19, 515 S.E.2d at 517. As long as the jury believed the
expert's testimony, there was no confusion over what it meant, and there was no
danger the jury would be misled. Similarly, in State v. Ramsey, 345 S.C. 607, 550
S.E.2d 294 (2001), the DNA expert testified his testing showed the victim's blood
on the defendant's boot, and "the chance the DNA on the boot did not come from
[the victim] was one in 4,601—a percentage greater than 99.9." 345 S.C. at 611,
550 S.E.2d at 296. As in Council, if the jury believed the expert, the defendant's
guilt followed logically from the expert's testimony.

In this case, however, Gallman's testimony—unlike the straightforward DNA
evidence from hair or bodily fluids in Council or Ramsey—involved three
fundamental concepts that are not at all straightforward: "touch DNA," "non-
exclusion DNA," and "random match probability." Though these DNA concepts
carry with them the same aura of reliability or invincibility, as we will explain, each
of them has significant potential to confuse and mislead that was not a factor in the
DNA evidence we addressed in Council or Ramsey.

will overvalue DNA evidence and ignore other types of evidence" (citing National
Research Council, THE EVALUATION OF FORENSIC DNA EVIDENCE 196-97 (1996);

value than deserved).
"Touch DNA" developed from advances in DNA technology that now permit
analysts to obtain fragments of DNA profiles from skin or other cells collected from
surfaces at crime scenes. One very important thing to understand about touch DNA
is that in many cases—this case included—the DNA analyst is not able to obtain a
full DNA profile from the "touch" sample. When the profile identifiable from the
sample is only a fragment of a full DNA profile, the case becomes less like Council
or Ramsey, and the analyst will be less able to identify the perpetrator or exclude any
given suspect. See Commonwealth v. Clark, 34 N.E.3d 1, 13 n.13 (Mass. 2015)
(stating "'touch DNA' or 'trace DNA'" emerged in 1997 after scientists "reported that
DNA profiles could be generated from touched objects," which "opened up
possibilities and led to the collection of DNA from a wider range of exhibits")
(quoting Roland AH van Oorschot, et al., Forensic Trace DNA: A Review, in 1:14
INVESTIGATIVE GENETICS 1, 2 (2010)); Bean v. State, 373 P.3d 372, 377 (Wyo. 2016)
(describing touch DNA in general terms).

Courts and legal commentators have recognized problems with the admission of
touch DNA evidence in criminal trials. The Texas Court of Criminal Appeals
recently wrote, "Touch DNA poses special problems because 'epithelial cells are
ubiquitous on handled materials,' because 'there is an uncertain connection between
the DNA profile identified from the epithelial cells and the person who deposited
them,' and because 'touch DNA analysis cannot determine when an epithelial cell
was deposited.'" Hall v. State, 569 S.W.3d 646, 658 (Tex. Crim. App. 2019)
(quoting Reed v. State, 541 S.W.3d 759, 777 (Tex. Crim. App. 2017)). Touch DNA
is sometimes referred to as "trace DNA." One commentator recently wrote, "These
trace samples lack the clarity of the more straightforward DNA evidence that can
lead to a clear match to a specific individual." Bess Stiffelman, No Longer the Gold
Standard: Probabilistic Genotyping Is Changing the Nature of DNA Evidence in
Criminal Trials, 24 Berkeley J. Crim. L. 110, 115 (2019); see also Dist. Attorney's
Office for Third Judicial Dist. v. Osborne, 557 U.S. 52, 82, 129 S. Ct. 2308, 2327,
174 L. Ed. 2d 38, 60 (2009) (Alito, J., concurring) (stating as to touch DNA that
"modern DNA testing technology is so powerful that it actually increases the risks
associated with mishandling evidence").

Gallman's testimony also included "non-exclusion" DNA evidence. Gallman stated,

             I take this person's DNA profile and I compare it to the
             information that was taken from the evidence. I check to
             see if their information is within this mixture and if their
             information is within this mixture, that means that I cannot
             exclude it, exclude them.
As with touch DNA, courts have identified problems with non-exclusion DNA. As
the Kentucky Supreme Court recently stated,

             [S]everal courts have held that DNA "match" or "non-
             exclusion" evidence is inadmissible without reliable
             accompanying evidence as to the likelihood that the test
             could or could not exclude other individuals in a given
             population. Without the accompanying evidence, these
             courts note "the jury have no way to evaluate the meaning
             of the result."

Duncan v. Commonwealth, 322 S.W.3d 81, 92 (Ky. 2010) (quoting Commonwealth
v. Mattei, 920 N.E.2d 845, 856 (Mass. 2010) (collecting cases)).

Gallman also testified to the related concept "random match probability." Of the
DNA concepts we have just discussed, random match probability has perhaps the
most potential for confusion. See State v. Bloom, 516 N.W.2d 159, 162 (Minn. 1994)
(recognizing that the "admission of the random match probability figure will confuse
jurors"). Random match probability is the likelihood that another randomly chosen
person—unrelated to the suspect—will have a DNA fragment identical to the
fragment the analyst found in the touch sample. The probability of a random match
in any given case depends on the size of the fragment the analyst can obtain from
the touch sample. Thus, the more complete the fragment, the less likely another
person could randomly match it. The smaller the fragment, on the other hand, the
more likely some other person will also have the identical fragment, and would then
be a "random match."

The Kentucky Supreme Court addressed random match probability in Duncan,
stating, "For smaller profiles, . . . those based on partial matches, . . . the odds of a
random match can be much higher and the inference that the source of the known
sample was also the source of the unknown sample much weaker." 322 S.W.3d at
90; see Bloom, 516 N.W.2d at 162 (describing the difficult chain of inferences a
juror must follow to get from the probability of a random match to an accurate
understanding of the likelihood of guilt (citing Jonathan J. Koehler, Error and
Exaggeration in the Presentation of DNA Evidence at Trial, 34 Jurimetrics J. 21, 35
(1993))).5 The Supreme Court of the United States addressed how random match

(7th ed. 2019) (cautioning "Care should be exercised as to how the statistic
probability creates risk that jurors will confuse it with a statistical probability of
guilt, referring to the risk as the "prosecutor's fallacy." McDaniel v. Brown, 558 U.S.
120, 128, 130 S. Ct. 665, 670, 175 L. Ed. 2d 582, 588 (2010) (citation omitted); see
also Ming W. Chin et al., FORENSIC DNA EVIDENCE: SCIENCE AND THE LAW § 5:2
(2019) (stating "the prosecutor's fallacy . . . confuses random match probability with
a source (or guilt) probability statement").6

Thus, even when the concepts of touch DNA, non-exclusion DNA, and random
match probability are completely and accurately presented to a jury, there is
significant potential the testimony will be confusing and misleading.

      III.   Analysis of Error

We have repeatedly discussed the trial court's "gatekeeping" role regarding the
admission of expert testimony. In Council, for example, we framed our discussion

Id. We have repeatedly enforced the requirement that trial courts exercise their
gatekeeping responsibility in admitting expert testimony. See, e.g., Graves v. CAS
Med. Sys., Inc., 401 S.C. 63, 75, 735 S.E.2d 650, 656 (2012) (affirming the trial
court's exclusion of the plaintiff's experts' opinions and stating "the court must . . .
exercise its role as gatekeeper"); Watson v. Ford Motor Co., 389 S.C. 434, 445, 699
S.E.2d 169, 174 (2010) (reversing the trial court's failure to exercise its role as
gatekeeper and stating "the trial court serves as the gatekeeper and must decide
whether the evidence submitted by a party is admissible pursuant to the Rules of
Evidence as a matter of law").

The proponent of scientific evidence has a corresponding responsibility to provide
the trial court the factual and scientific information the court needs to carry out its
gatekeeping duty. In Council, Graves, and Watson, the proponent went to great
lengths in a hearing outside of the jury's presence to provide a sufficient factual and
scientific basis for the court to consider as gatekeeper. In Council, the State
presented live, detailed testimony from the FBI expert explaining the history of the
mitochondrial DNA analysis method, his training in the method, and precisely how
the method is used. 335 S.C. at 17-18, 515 S.E.2d at 516-17. Similarly, in Graves
and Watson, the civil plaintiffs who sought to introduce the opinion testimony
presented deposition testimony of their experts and/or live testimony outside the
presence of a jury,7 and each expert explained in detail the factual and scientific basis
for their opinions. Graves, 401 S.C. at 70-72, 735 S.E.2d at 653-54; Watson, 389
S.C. at 447-48, 699 S.E.2d at 176.

In this case, the State did basically nothing to give the trial court a sufficient factual
and scientific basis upon which to carry out its gatekeeping responsibility. First, the
State did not call Gallman—or any witness with any knowledge of Gallman's
testimony or its factual or scientific basis—to testify at the hearing on Phillips'
motion to exclude her testimony. Under that circumstance alone, it was impossible
for the trial court to meaningfully determine whether Gallman's testimony satisfied
the Rule 702 elements, or should be excluded under Rule 403.

Second, the State made almost no effort to educate the trial court on the factual and
scientific basis of Gallman's opinions. Before any expert opinion may be admitted
into evidence, the proponent of the opinion must convince the trial court that each
element of the Rule 702 foundation has been established. See State v. Von Dohlen,

7
 In Graves, the testimony was presented in a pre-trial Daubert/Council hearing. See
401 S.C. at 73, 735 S.E.2d at 655 (describing the trial court's analysis of the expert's
depositions before excluding the expert opinion and granting summary judgment).
322 S.C. 234, 248, 471 S.E.2d 689, 697 (1996) ("The party offering the expert has
the burden of showing his witness possesses the necessary learning, skill, or practical
experience to enable the witness to give opinion testimony."), overruled on other
grounds by State v. Burdette, 427 S.C. 490, 832 S.E.2d 575 (2019); see also United
States v. Williams, 865 F.3d 1328, 1338 (11th Cir. 2017) (stating "the proponent of
expert testimony bears the burden of demonstrating the expert's qualifications and
competence to give his proposed testimony"). In addition, when the opponent makes
a Rule 403 objection, the proponent must demonstrate the probative value of the
evidence. In the pre-trial hearing in this case, the only person who spoke on behalf
of the State was the assistant solicitor. She spoke only briefly, and to the extent she
said anything about the concepts of touch DNA, non-exclusion DNA, or random
match probability, the statements she made were mostly wrong. We will address her
incorrect statements below.

Gallman did address each concept in her testimony before the jury, but the assistant
solicitor never asked Gallman any questions that allowed her to explain the concepts
in detail. As to touch DNA, Gallman described it generally as follows,

             But when you talk about touch DNA, it's based on whether
             -- like I say, touch DNA, whether I touch an item or I
             didn't. You can touch an item and still you will not get a
             full DNA profile from that touch. So touch DNA is
             basically like a luck of the draw, whether you leave your
             cells or you didn't or you left a couple of cells, but it wasn't
             enough information to detect that you were there.

Shortly after this testimony, the assistant solicitor asked Gallman if she obtained a
full DNA profile for the standards, asking, "Were you able to develop a full profile
and get all sixteen numbers for the defendant, Billy Phillips?" Gallman answered,
"Yes." Immediately thereafter, however, "Turning your attention to the items of
evidence that you tested," as she directed Gallman, the assistant solicitor did not ask
Gallman whether she got a full DNA profile from the touch samples. Gallman then
proceeded to make three statements that incorrectly indicated she did get a full DNA
profile from the gun. She testified with respect to the gun, "With this particular
sample, when I developed the DNA profile of the DNA obtained from it," and "it's
basically a genetic footprint or fingerprint of who had potentially touched the gun,"
and "I was developing a DNA profile from whatever skin cells were left there." At
no other point did the assistant solicitor ask Gallman to give any explanation of the
nature of touch DNA, particularly the significant fact that the touch DNA samples
in this case revealed only fragments, not full DNA profiles.
In subsequent testimony, Gallman hardly explained that the touch DNA samples
revealed only a fragment of a full DNA profile. Gallman referred to the samples not
as fragments, but as "the swab from the gun" and "the swab from the right front
pocket." Finally, she testified,

             [W]e're able to develop a DNA profile from evidence and
             then also develop a DNA profile from a standard. It could
             be from a person's blood or what we call a buccal swab,
             when they swab inside someone's, within your mouth, and
             compare that to the evidence to see whether it matches or
             it does not match.

The striking omission of a meaningful explanation that the touch samples Gallman
obtained in this case revealed only fragments of a full DNA profile left the jury with
the incorrect impression Gallman matched Phillips' DNA standard with a full DNA
profile he left behind on the gun and in the pocket.

In similar fashion, the State elicited from Gallman only general descriptions of non-
exclusion DNA and random match probability. Of the concerns recited by the courts
and academic authorities discussed above, the State addressed none of them. We
are particularly troubled by the State's failure to elicit from Gallman any explanation
of the method she used to calculate the probability that some other person—not
Phillips—contributed the DNA on the gun or in the jeans pocket. As Gallman
testified, she is "required to tell you how often you would see this mixture in a
population." There must, however, be some method she followed in arriving at this
probability. She explained no method, stating only, "So based on the information
that I could use to generate a statistic, the value is one in two hundred." As to the
jeans pocket, she stated only, "I compared the DNA [standards] to the evidence . . .
and the next step is to give a statistical value to that mixture, and the probability of
randomly selecting an unrelated individual who could have contributed to this
mixture is approximately one in two."

The method of making these calculations is undoubtedly complicated. As some of
the academic writers referred to above stated, "The formulas used to determine
statistical probability of a match produce a result that is difficult for a layperson to
understand," Boies, supra, at 417, and, "The complexity of mathematical
computations used to determine the probability of a match may leave jurors with
some degree of confusion and uncertainty," Lieberman, supra, at 32. The difficulty
of making or explaining the calculation does not mean, however, the method for
doing so may be ignored. Rather, the method by which a DNA analyst calculates
random match probability must be explained. "To say that two patterns match,
without providing any scientifically valid estimate . . . of the frequency with which
such matches might occur by chance, is meaningless." National Research Council,
supra note 2, at 9 (emphasis added).

In addition, much of the information the State did provide the trial court and jury
was simply wrong. We begin with the assistant solicitor's presentation to the trial
court in the pre-trial hearing. Following up on her answer to the court's question in
which she stated three people—including Phillips—could not be excluded from the
mixture of DNA found on the gun, the assistant solicitor said, "That means their
DNA is there, and if [defense counsel] had spoken to Ms. Gallman, . . . she would
have been able to explain that to him." The court then asked her, "Well, are you
saying that Billy Phillips' DNA is on the weapon," to which she responded, "It is."

The assistant solicitor's statements are wrong. She appeared to recognize her error
moments later when she stated, "Your Honor, I mis-spoke." She then proceeded,
however, to make another series of incorrect statements. She said, "It does not say
that it is 100% Billy Phillips' DNA in that mixture of contributors, but it says that he
cannot be excluded as a contributor to the three. It also lists two other names.
'Cannot be excluded' means the same thing as can be included." She then stated,
"The DNA itself, it stands for itself."

Actually, if defense counsel had talked to Gallman, Gallman would certainly have
told him she did not know whether Phillips' DNA was on the gun, or in the jeans
pocket. She would also have told him "cannot be excluded" most certainly does not
mean "can be included,"8 and she would have taken pains to be clear the DNA does
not "stand for itself." Rather, DNA—particularly touch DNA—is a complicated
scientific field of study that requires detailed explanation given by a trained scientist
like Gallman, elicited by an experienced trial lawyer who has taken the time to
prepare herself for trial.

8
  The State's casual use of scientific terms is striking. When Gallman testified she
could not exclude Phillips as a contributor, she meant that whatever fragment of a
DNA profile she found on the evidence matched a fragment of Phillips' full DNA
profile. The corollary to her "cannot be excluded" testimony as to Phillips is that a
DNA fragment identical to Phillips' fragment is included. That is not the same as
saying Phillips' full DNA profile is included. In fact, Gallman does not know whose
DNA is in the mixture; she knows only that she found a DNA fragment that could
have been left by quite a few people.
In Gallman's testimony, there were more incorrect statements. Responding to
confusing questions from the assistant solicitor, Gallman conflated (1) a finding that
an individual can be excluded as a contributor to a DNA mixture with a finding that
the excluded individual never touched the item, and (2) a finding that a fragment of
a person's DNA is on an item with a finding the person touched the item.

             SOLICITOR: Okay. So, using again, I guess an example
             of, say, these scissors. If I had never touched the scissors
             and did not leave any cells on it, would the language be,
             could not be excluded, or would it be outright excluded?

             GALLMAN: It would be excluded.

             SOLICITOR: Okay. So, if multiple people have handled
             the scissors, and you're able to get numbers, DNA numbers
             off of the scissors and you find that there's at least three,
             that just means that I have left part of my DNA on there.
             Correct?

             GALLMAN: It means that you left cells, skin cells on that
             item.

We do not fully understand the assistant solicitor's questions, so Gallman probably
did not understand them either. The answers, however, are wrong. As to the first
answer, if the assistant solicitor never touched the scissors, but another person who
did touch them left a DNA fragment behind that is identical to a fragment in the
assistant solicitor's DNA profile, Gallman could not have excluded the assistant
solicitor because Gallman would not know which of the two left the fragment. The
incorrect answer suggests that if Phillips had not touched the gun or had his hand in
the jeans pocket, he would have been excluded. To the contrary, it is entirely
possible that Phillips did not put his hand in Woods' pocket, but someone with an
identical DNA fragment did, and still Gallman could not exclude Phillips as a
contributor. As to the jeans pocket, the assistant solicitor's confusing question and
Gallman's incorrect answer wrongly suggest we know Phillips had his hand in
Woods' pocket. We do not know that.

As to the second answer, if multiple people touched the scissors, and one of them
left behind a DNA fragment identical to a fragment in the assistant solicitor's DNA
profile, that does not mean the assistant solicitor left cells there. This is in fact the
concept of random match probability the State failed to explain. There is always
some chance another person left those cells, but the person has an identical DNA
fragment. So, only one of the two touched the item, but neither can be excluded.
The answer suggests—wrongly—Gallman was giving her opinion that Phillips had
his hand in the pocket. She was not.

Also as to the second answer, there are other plausible ways a fragment of a person's
DNA might be found on the scissors when the person did not themselves touch them.
"Touch DNA is . . . subject to what is known as secondary transfer. This refers to
the 'possibility that an individual or an object may serve as a conduit between a
source and a final destination without any direct encounter.'" Bean, 373 P.3d at 377-
78 (quoting 4 David L. Faigman et al., MODERN SCIENTIFIC EVIDENCE: THE LAW
AND SCIENCE OF EXPERT TESTIMONY § 30:13 (2015–2016 ed.)); see also 7 Clifford
S. Fishman & Anne T. McKenna, JONES ON EVIDENCE § 60:10 (7th ed. 2019)
(explaining "'Secondary transfer' occurs when DNA left on one surface is
inadvertently transferred to another surface" and noting "the risk is greatest with
regard to touch DNA"). In other words, it is quite possible the assistant solicitor
never touched the scissors, but cells she left on another surface were transferred there
and tested as part of the touch DNA sample. In that event—contrary to Gallman's
second answer—the assistant solicitor's DNA was on the scissors, but she had not
left DNA there.

We review a trial court's decision to admit or exclude evidence under a deferential
standard for an abuse of discretion. State v. Dickerson, 395 S.C. 101, 116, 716
S.E.2d 895, 903 (2011). In this case, however, the State did not give the trial court
the factual and scientific basis the court needed to meaningfully exercise that
discretion. The trial court was essentially left in the dark as to the difficult concepts
of touch DNA, non-exclusion DNA, and random match probability. As to the
misstatements made by the assistant solicitor and Gallman, the trial court was kept
out of the position of even suspecting the statements might be incorrect.

We are aware that our "analysis of error" reads as if we are second-guessing the trial
court. However, because the trial court did not require the State to present the factual
and scientific foundation for Gallman's testimony in a Daubert/Council hearing
before she testified to the jury, we are actually conducting the analysis for the first
time. The trial court should have required the State to present the factual and
scientific information necessary to establish the foundation required by Rule 702.
The trial court also should have conducted an on-the-record balancing of probative
value and the danger of confusion of the issues and misleading the jury required by
Rule 403. In that event, instead of conducting our own analysis, we could review
the trial court's analysis under the proper standard of deference.

The root of the trial court's error, however, is a series of failures by the State. First,
the State failed to present the testimony of its expert witness at the hearing at which
the trial court was to consider the admissibility of the expert's opinion. Second, the
State presented an incomplete factual and scientific basis for the admission of the
expert's opinion. Third, the State did not explain to the jury the complicated DNA
concepts involved in this case. Fourth, the State presented incorrect information
about its DNA evidence. Finally—as we will explain—the assistant solicitor
misstated to the trial court and the jury that Phillips' DNA was on the gun and in the
jeans pocket.

      IV.    Harmless Error

The State argues that even if the trial court erred in admitting Gallman's DNA
testimony, the error was harmless. We disagree. While the State presented
considerable circumstantial evidence supporting Phillips' guilt, it did not offer any
evidence that conclusively proved Phillips' guilt. See State v. Pagan, 369 S.C. 201,
212, 631 S.E.2d 262, 267 (2006) (stating "an insubstantial error not affecting the
result of the trial is harmless where 'guilt has been conclusively proven . . . such that
no other rational conclusion can be reached.'" (quoting State v. Bailey, 298 S.C. 1,
5, 377 S.E.2d 581, 584 (1989))).

As part of our harmless error analysis, we review "the materiality and prejudicial
character of the error" in the context of the entire trial. State v. Byers, 392 S.C. 438,
447-48, 710 S.E.2d 55, 60 (2011). To evaluate this context, we must consider the
assistant solicitor's misstatements. In addition to those already discussed, she told
the trial court in response to Phillips' directed verdict motion, "I believe with his
DNA being on the murder weapon, along with other things, along with the
eyewitness testimony, there is absolutely substantial evidence." The trial court then
asked, "Is his DNA actually on there?" She responded, "His DNA is on the gun in
the form that he cannot be excluded." Both statements are wrong.

More importantly, however, the assistant solicitor made misstatements in her closing
argument to the jury. On several occasions she repeated the false statement that if a
person does not touch an item he will be excluded. She stated, for example, "If you
don't touch it, you are automatically excluded. One hundred percent excluded." She
also told the jury Gallman found Phillips' DNA on the gun and in the jeans pocket.
She stated, "Well, we have his DNA on that gun," and "We also know that
defendant's DNA is on the murder weapon and inside [Woods'] pocket," and "Had
he not touched the gun or the pocket, his DNA would not be there."

The "prosecutor's fallacy" the Supreme Court and Justice Chin warn about involves
risk the jury might unknowingly or accidentally confuse the complicated concepts
underlying DNA evidence. Such innocent confusion was certainly a risk in this case.
We need not determine whether the risk of innocent confusion materialized in this
case, however, because the incorrect statements in closing argument all but
guaranteed the jury was confused and misled. If there were any possibility we might
find the error of admitting the evidence harmless, the assistant solicitor extinguished
that possibility with her incorrect statements in her closing argument. See Duncan,
322 S.W.3d at 91-93 (finding it was improper for prosecutor to state in closing
argument that "not excluded" was the same as "included," and holding "given the
immense weight jurors are apt to accord DNA evidence," the prosecutor's statements
"rendered [the defendant's] trial manifestly unfair"); Whack, 73 A.3d at 189 (finding
trial court erred in denying mistrial because prosecutor in closing argument "told
jurors that [defendant's] DNA was present" when expert actually testified "she could
not exclude [defendant] as being the source of DNA"); Bloom, 516 N.W.2d at 169
(stating "we will not hesitate to award a new trial . . . if . . . DNA identification
evidence was presented in a misleading or improper way").

      V.     Conclusion

DNA evidence is a complicated scientific subject. In Council, we held "the trial
judge was well within his discretion in finding the results of the [mitochondrial]
DNA analysis admissible." 335 S.C. at 21, 515 S.E.2d at 518. That does not mean
that every time a party offers DNA evidence it is admissible. Rather, if an objection
is made, the trial court must hold a Daubert/Council hearing, the proponent of the
evidence must present the factual and scientific basis necessary to satisfy the
foundational elements of Rule 702, and the trial court must conduct an on-the-record
balancing of probative value against the applicable Rule 403 dangers. The trial court
should make specific findings as to each contested element or issue.

By not conducting a Daubert/Council hearing, the trial court left itself without a
meaningful opportunity to exercise its discretion. The State failed to establish the
"assist the trier of fact" element, and the probative value of the DNA evidence is
substantially outweighed by danger the evidence would confuse the issues and
mislead the jury. We reverse Phillips' convictions and remand for a new trial.
REVERSED.

KITTREDGE, HEARN and JAMES, JJ., concur. BEATTY, C.J.,
concurring in result only in a separate opinion.
       CHIEF JUSTICE BEATTY: Respectfully, I concur in result. While I agree
with the conclusion reached by the majority, I disagree with the majority's reference
to a "Daubert/Council" hearing. Because this Court has expressly declined to adopt
Daubert,9 I believe the majority's instruction regarding a "Daubert/Council" hearing
is confusing and constitutes an implicit adoption of Daubert.

       As the majority correctly recognizes, in State v. Council, 335 S.C. 1, 515
S.E.2d 508 (1999), this Court was presented with an opportunity to analyze the
admissibility of expert opinion on DNA evidence under the new South Carolina
Rules of Evidence. In Council, this Court identified the procedure trial judges
should use in deciding whether to admit scientific evidence. Specifically, the Court
stated:

               While this Court does not adopt Daubert, we find the proper
        analysis for determining admissibility of scientific evidence is now
        under the SCRE. When admitting scientific evidence under Rule 702,
        SCRE, the trial judge must find the evidence will assist the trier of fact,
        the expert witness is qualified, and the underlying science is reliable.
        The trial judge should apply the Jones[10] factors to determine
        reliability. Further, if the evidence is admissible under Rule 702,
        SCRE, the trial judge should determine if its probative value is
        outweighed by its prejudicial effect. Rule 403, SCRE. Once the
        evidence is admitted under these standards, the jury may give it such
        weight as it deems appropriate.

Id. at 20–21, 515 S.E.2d at 518 (emphasis added).

       Since 1999, Council has remained the standard by which trial judges have
decided whether to admit scientific evidence. Although our appellate courts have
referenced Daubert in at least ten cases since 1999, our courts have consistently
adhered to Council and repeatedly declined to adopt Daubert. See, e.g., State v.
Jones, 383 S.C. 535, 548 n.5, 681 S.E.2d 580, 587 n.5 (2009) (citing Council and
reiterating that the Court declined to adopt Daubert); State v. Warner, No. 5717,
2020 WL 1696716, at * 3 (Ct. App. Apr. 8, 2020) ("South Carolina has not adopted
Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 594-95, 113 S. Ct.

9
 Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579 (1993) (adopting new standard
for determining the admissibility of scientific evidence under Rule 702 of the Federal
Rules of Evidence).
10
     State v. Jones, 273 S.C. 723, 259 S.E.2d 120 (1979).
2786, 125 L. Ed. 2d 469 (1993), by name, nor has it revised Rule 702, SCRE, to
incorporate the Daubert framework. Nevertheless, our approach is 'extraordinarily
similar' to the federal test." (citation omitted)).

      Without explanation, the majority departs from more than twenty years of
precedent and appears to implicitly adopt Daubert by creating a hybrid
Daubert/Council test. I believe this departure is unwarranted and will create
confusion. Although our appellate courts have recognized the similarities between
Daubert and Council, there is a distinction that caused this Court to decline to adopt
the Daubert test. The majority has neither addressed this distinction nor outlined the
procedure in the new test.

       As the majority aptly points out, trial judges are the gatekeepers regarding the
admission of scientific evidence and expert testimony. In order to fulfill this
significant role, our judges must have a clear understanding of the correct test for
admissibility. I believe Council remains the correct test.

        Having addressed my substantive concerns with the majority's opinion, I now
turn to an observation that is equally concerning. As part of its analysis, the majority
castigates the prosecutor in this case. To some extent, this rebuke is warranted. The
prosecutor was at times evasive, if not misleading, when responding to some of the
trial judge's questions and arguing before the jury. Yet, it is questionable whether
this was intentional. Further, the prosecutor does not bear sole responsibility of
ensuring that only admissible evidence is put before the judge and jury. Rather, the
primary responsibility lies with the judge, who is the gatekeeper regarding the
admission of all evidence.

      Based on the foregoing, I concur in the majority's decision to reverse Phillips's
convictions and remand for a new trial. On remand, if an objection is raised
regarding the DNA evidence, I believe the trial judge must hold a hearing in
accordance with Council.
