OPINION
JUSTICE WECHT DECIDED: December 17, 2024
Derek Murchison was convicted of first-degree murder1 (and related charges) for
the October 5, 2001, strangulation of Linda Willis and was sentenced to life in prison
without the possibility of parole. Murchison later sought and obtained post-conviction
DNA testing of various items found at the murder scene under the Post Conviction Relief
Act (“PCRA”).2 Upon receiving the results, Murchison filed a petition for post-conviction
relief, arguing that the new DNA test results constituted after-discovered evidence that
entitled him to a new trial.3
1 See 18 Pa.C.S. § 2502(a). 2 See 42 Pa.C.S. § 9543.1 (entitled “Postconviction DNA testing”) 3 See 42 Pa.C.S. § 9543.1(f)(1) (authorizing a petitioner to file a petition for post- conviction relief pursuant to Section 9543(a)(2)(vi) (relating to after-discovered evidence) at the conclusion of the DNA testing requested under Section 9543.1). The PCRA court dismissed the petition, and the Superior Court affirmed. We
granted allowance of appeal to determine whether the lower courts applied the correct
legal standard for after-discovered evidence claims predicated upon post-conviction DNA
testing. We hold that the same standard applies to all after-discovered evidence claims,
regardless of the character of the new evidence, including DNA evidence. Accordingly,
we affirm.
Willis was found dead in her home on October 5, 2001. The house lacked
electricity and running water and was filled with trash and disordered furniture. The
windows were boarded up, and the front door could be locked only by sliding a piece of
wood from a bed slat into the door handle. Willis was addicted to crack cocaine and was
known to allow other addicted persons to use crack cocaine in her home in exchange for
drugs and money. She also permitted people to live in her home or to have sex with her
in exchange for drugs or money. For instance, Willis rented rooms to Michael Cannon
and Karen Thomas. Cannon paid Willis $50 twice per month for a room on the third floor,
and sometimes paid Willis for sex. Cornell Mayrant also spent considerable time at the
house and was in an intimate relationship with Willis. As a result, at the time of her
murder, Willis’ home was frequented by many people who shared her drug addiction.
A few years before Willis was murdered, Murchison had rented a room from her.
At the time of the murder, Murchison no longer lived there, but he had continued to spend
time with Willis at the home since moving out. The two engaged in a practice whereby
Murchison would steal clothes from the retail store that employed him, and Willis, in turn,
would sell the stolen clothes on the street. They would then use the profits to purchase
crack cocaine.
[J-74-2024] - 2 In July 2001, Cannon, who was not addicted to cocaine but consumed alcohol
every day, rented a room from Willis. Cannon awoke daily at 6:00 a.m. and departed
around 6:45 a.m. in order to meet friends and spend the day drinking. Each evening he
would purchase a bottle of alcohol on the way home and would return to his room and
drink until he fell asleep. On the evening of October 4, 2001, Cannon returned home to
his room, as usual. At around 11:00 p.m., Cannon heard Willis call his name, but he
ignored her because he suspected that she was going to ask him for money. Cannon did
not hear any sounds of a struggle thereafter.
The next morning, Cannon awoke at his usual time. On his way out of the house,
Cannon twice walked by Willis, who lay sprawled on the couch. Cannon believed that
Willis was sleeping. Because of the boarded-up windows and lack of electricity, the room
was very dark. When Cannon returned home that evening, he observed Willis in the
same position on the couch. The room still was dark, and Cannon could not see Willis
clearly. Cannon did not attempt to interact with Willis and, instead, returned to his room
with the bottle of alcohol that he had brought home. After finishing the bottle, Cannon
decided to leave the house to purchase another bottle before the liquor store closed at
9:00 p.m. When Cannon entered the living room, he again noticed that Willis was still on
the couch. Thinking it odd that she had not moved, Cannon approached Willis, intending
to wake her. In the darkness, Cannon shook Willis, and quickly realized that she was
dead. Unbeknownst to Cannon, who could not see clearly in the darkness, there was
dried blood on Willis’ face. Cannon also was standing in a pool of blood that had gathered
on the floor next to the couch. Willis was not wearing any pants, and her underwear was
strewn on the floor next to the couch. Because there was no phone in the house, Cannon
[J-74-2024] - 3 asked a neighbor to call the police. The neighbor refused. Cannon walked to a payphone
and called the police himself.
When police officers responded, they had to use flashlights to investigate the dark
crime scene. The police officers and other first responders found the wooden bed slat
that was used to secure the front door lying on the floor next to the couch. There was
blood on the wooden slat, which suggested to investigators that it had been against Willis.
It also appeared to investigators that Willis had been beaten with fists. A toy fire truck
was recovered atop the wooden slat, and officers found a white towel and a gray blanket
on the floor near the couch. Investigators collected all of these items as evidence for
forensic DNA testing. Because some blood was found on Cannon when police officers
arrived, investigators also collected Cannon’s boxer shorts, jeans, and socks. None of
the pre-trial DNA testing that was performed on any of these items linked Murchison to
the scene.
Willis had been dead for a significant period of time before police officers arrived.
The medical examiner estimated that Willis had been killed between midnight and noon
on October 5, 2001, or possibly even earlier. Following autopsy, Willis’ cause of death
was determined to be asphyxiation by manual strangulation. Willis’ body also exhibited
extensive bruising and other indicia of blunt force trauma, all consistent with strikes from
a blunt object. Toxicology tests revealed that Willis had ingested cocaine up to an hour
before her death. Although Willis was found naked from the waist down, there was no
evidence of sexual assault. No semen was found in or on Willis. No fingerprint evidence
linked Murchison to Willis’ murder. Investigators found no fingerprints on the wooden slat
[J-74-2024] - 4 that they believed had been used to assault Willis. A partial fingerprint from the toy truck
proved insufficient for identification.
Police officers interviewed Thomas, one of the house’s occupants, on the night of
October 5, 2001. Thomas stated that, sometime between 2:00 and 3:00 a.m. on October
5, 2001, she ran into Murchison on the sidewalk about two blocks from Willis’ house.
Murchison was carrying a bag of clothing that he was attempting to sell. Thomas asked
Murchison where he was coming from. Murchison responded that he had just been to
Willis’ house and “that bitch put me out.”4 Murchison asked Thomas if she knew to whom
Willis usually sold the stolen clothes. When Thomas declined to answer the question, the
two parted ways. When talking to the police investigators, Thomas referred to Murchison
only as “Derrick,” because she did not know his last name.
The investigation into the murder then stalled. There was no evidence against
Cannon, aside from his discovery of Willis’ body. Police officers investigated Mayrant
because of his apparent relationship with Willis, but found no evidence suggesting that
he was the person who killed her. Police suspected “Derrick” based upon their interview
with Thomas, but, at the time, they did not know that “Derrick” was Murchison. This
changed three months later, when Carolyn Hunt, the mother of two of Murchison’s
children, called police and reported that Murchison had confessed to Willis’ murder.
Hunt and Murchison had been estranged until Murchison began calling her in 2001
in order to speak to their children. In January 2002, Murchison went to Hunt’s house and
asked to talk with her. Hunt could tell that Murchison was high and, because it appeared
to her that he had been sleeping on the street, she did not let him into her home. Instead,
4 PCRA Ct. Op., 6/25/2020, at 3.
[J-74-2024] - 5 they talked in her car. Murchison asked if she had heard about what happened to Willis.
Hunt told him that she had heard that Willis had been raped and beaten to death.
Murchison replied, “that’s not how it happened.”5 Murchison explained that Willis had not
been raped, that he and Willis had been spending time together getting high and selling
the stolen clothes. On the night of the murder, Willis “came back short” on the money
that she was supposed to give Murchison.6 Murchison and Willis began to argue.
Murchison then punched Willis in the face until she passed out. When Willis came to,
Murchison started choking her. Willis again passed out, and again came to. Murchison
told Hunt that he then “grabbed the stick and he hit her with the stick.”7
Terrified of what she had heard, Hunt sent Murchison away. Fearing for her
children’s safety, Hunt moved them to another school so that Murchison could not find
them. Hunt told her sister and her mother about the confession. After a week of trying to
figure out what to do, Hunt called police and reported Murchison’s confession. Officers
soon arrested Murchison for the murder.
Murchison later wrote Hunt a letter from jail in which he insisted that Willis was “like
that when I found her.”8 Murchison warned Hunt that she should “think about what [she
was] saying,” because she “made a very, very big mistake.”9 Hunt considered this to be
a threat. Hunt’s sister, Nola Rutledge, corroborated Hunt’s testimony. Rutledge testified
5 N.T., 6/15/2004, at 86 (R.R. at 345a). 6 N.T., 6/15/2004, at 86 (R.R. at 345a). 7 N.T., 6/10/2004, at 132-33 (R.R. at 204a-05a). 8 N.T., 6/10/2004, at 143 (R.R. at 207a). 9 N.T., 6/10/2004, at 143 (R.R. at 207a).
[J-74-2024] - 6 that, in January 2002, Hunt told Rutledge about Murchison’s confession and that Hunt
responded by transferring her children to another school in order to protect them from
Murchison.
Investigators found Hunt’s report of Murchison’s confession to be particularly
credible because it matched information they already had, including Thomas’ reference
to “Derrick,” the lack of evidence of any kind of sexual assault, the use of the wooden slat,
and the cause of death finding of manual strangulation, a process known to be slow and
in which the victim often passes out and sometimes revives.
Pursuing this new information, police officers interviewed Dasheika Bowie, the
mother of four of Murchison’s children, with whom Murchison had been living in October
2001. According to Bowie, at the beginning of October 2001, when she and Murchison
shared a residence, Murchison disappeared for a few days. Because of Murchison’s drug
addiction, it was not unusual for him to disappear for a while at the beginning of the month
after he received his welfare check. When Bowie next encountered Murchison, it looked
to Bowie as if Murchison had been in a fight. Murchison had a black eye, scratches on
his face, and a busted lip. Murchison explained that he had gotten into a fight with a man
and that the man’s girlfriend had jumped in. Murchison told Bowie that he hit the girlfriend
with a stick. The man told Murchison to “finish her off.”10 Murchison told Bowie that he
declined and that both men left the house without knowing whether the girlfriend was
dead or alive.11 Murchison did not identify the woman, but did explain that the fight had
been over crack cocaine.

[J-74-2024] - 7 After police officers arrested Murchison, he twice attempted to escape. On August
3, 2002, Murchison attempted to escape the police station by climbing through the ceiling
of an interview room while awaiting interrogation. He was quickly apprehended. In the
second attempt, a Sheriff’s detective thwarted Murchison’s attempt to escape an interview
room at the courthouse by climbing through a circulation vent in the ceiling. The
Commonwealth later would rely at trial upon these escape attempts in order to establish
Murchison’s consciousness of guilt.
In addition to the evidence summarized above, the Commonwealth introduced
DNA evidence from the crime scene. None of that DNA evidence implicated Murchison.
DNA material taken from Willis’ fingernails excluded Cannon, Mayrant, and Murchison,
and instead revealed contributions from two unknown males. The medical examiner
testified that, in cases of manual strangulation, victims often scratched their own neck
rather than their attacker. The medical examiner further explained that DNA material
could remain for a long time under the fingernails of someone with poor hygiene.
Blood samples from the toy fire engine showed Willis as the source. DNA material
recovered from blood stains on the wooden slat also belonged to Willis. Attempts to
obtain fingerprints from the wooden slat proved unsuccessful.
DNA testing of blood and semen stains found on the gray blanket identified Willis
as the contributor of the blood and excluded Mayrant, Cannon, and Murchison. Partial
DNA profiles of at least three unknown male contributors were recovered from semen
deposits on the blanket. DNA testing of semen deposits found on the white towel
excluded Murchison and Mayrant and could not exclude Cannon. DNA from two unknown
males also was found in the semen on the towel.
[J-74-2024] - 8 DNA from a blood stain on Cannon’s sock included Willis as a contributor. DNA
testing available at the time of trial did not identify contributors to blood found on Cannon’s
boxers and jeans but could not exclude Willis as the source.
Without forensic evidence connecting Murchison to the crime scene, the
Commonwealth relied heavily upon testimony from Cannon, Thomas, Bowie, and Hunt.
On June 16, 2004, a jury found Murchison guilty of first-degree murder, possession
of an instrument of crime, and escape.12 On August 10, 2004, the trial court sentenced
Murchison to life in prison without the possibility of parole.
After reinstating Murchison’s appellate rights nunc pro tunc, the Superior Court
affirmed his judgment of sentence.13 On October 17, 2008, this Court denied allocatur.14
On January 9, 2009, Murchison filed a PCRA petition alleging that his trial and appellate
counsel were ineffective. The PCRA court dismissed the petition without an evidentiary
hearing and, on May 3, 2011, the Superior Court affirmed.15
Advances in DNA testing technology in the years since Murchison’s conviction
include new recovery techniques, especially what is now known either as touch DNA or
contact trace DNA. This is a forensic method for analyzing trace amounts of DNA left at
the scene of a crime, and includes, for example, skin cells from an object that has been

Super. 2006) (affirming the judgment of sentence because Murchison waived his appellate claims); Commonwealth v. Murchinson, 708 EDA 2007 (Pa. Super. Apr. 28, 2008) (reinstating Murchison’s appellate rights nunc pro tunc) (unpublished). 14 Commonwealth v. Murchison, 286 EAL 2008 (Pa. Oct. 17, 2008) (per curiam). 15 Commonwealth v. Murchison, 1574 EDA 2010 (Pa. Super. May 3, 2011).
[J-74-2024] - 9 handled or touched, or cells from footprints. This new technology enables the collection
of DNA from traces of blood, skin cells, sweat, semen, tears, or mucus that may remain
on a surface.
On October 18, 2012, Murchison filed a petition for post-conviction DNA testing.16
On June 13, 2013, the PCRA court granted the petition and ordered DNA testing of certain
evidentiary items that remained in Commonwealth custody. After the testing was
complete, on September 4, 2015, Murchison filed a PCRA petition alleging that the new
DNA test results met the criteria for after-discovered evidence under the PCRA. The case
then was continued several times to await the conclusion of additional DNA testing.
Murchison’s claim ultimately rested upon three reports, dated June 15, 2015, July
6, 2015, and May 4, 2016. These reports compared the new DNA findings to the results
of the initial pretrial testing. Pretrial forensic testing of blood stains on the wooden slat
established the presence of DNA consistent with Willis’ genetic profile and did not detect
DNA from any other contributor. The results of the new DNA testing revealed the
presence of trace DNA from an unknown contributor who could not have been Murchison.
Mayrant could not be excluded as a contributor to the trace DNA deposited from an area
of the slat that was not blood-stained.
Pretrial DNA testing proved that Willis was a contributor to a blood stain on the
heel of Cannon’s sock. The new testing showed the presence of DNA from a second,
unknown contributor. The testing conclusively determined that this additional contributor
was not Murchison. Pretrial DNA testing did not identify contributors to a blood stain on
16 See 42 Pa.C.S. § 9543.1.
[J-74-2024] - 10 Cannon’s boxer shorts and did not exclude Willis as the source. The new testing identified
Willis as the source of that blood.
Pretrial DNA testing detected three unknown contributors for the semen found on
the blanket. The new DNA testing excluded Murchison from this group, and even
established a fourth unknown male contributor.
Pretrial DNA testing could not exclude Cannon as a contributor to the semen found
on the towel, excluded Mayrant and Murchison, and identified two unknown contributors.
The new DNA testing likewise excluded Murchison as a contributor to the semen and
confirmed the existence of two unknown male contributors.
In his PCRA petition, Murchison argued that these new DNA test results
constituted after-discovered evidence that entitled him to relief under Section
9543(a)(2)(vi). That section requires a petitioner to “plead and prove by a preponderance
of the evidence” “[t]hat the conviction or sentence resulted from” “[t]he unavailability at
the time of trial of exculpatory evidence that has subsequently become available and
would have changed the outcome of the trial if it had been introduced.”17 Murchison
argued that, because all of the DNA testing had excluded him as a contributor, the new
DNA testing was necessarily exculpatory.
Murchison sought a new trial, or, in the alternative, an opportunity to negotiate a
new plea deal with the Commonwealth. Murchison offered to plead nolo contendere to
third degree murder and to possession of an instrument of crime in exchange for a
reduced sentence of twenty to forty years of incarceration. On July 9, 2019, the
Commonwealth submitted a letter to the PCRA court asserting that, “after thoroughly
17 42 Pa.C.S. § 9543(a).
[J-74-2024] - 11 reviewing the DNA testing results and the trial notes, the Commonwealth will agree to
PCRA relief.”18 The Commonwealth agreed to accept Murchison’s plea offer.
On October 29, 2019, the PCRA court nonetheless provided notice of its intent to
dismiss the PCRA petition without an evidentiary hearing.19 On November 15, 2019,
Murchison filed a reply to the dismissal order. On November 27, 2019, the PCRA court
dismissed the petition as untimely and without merit. On December 17, 2019, Murchison
filed a notice of appeal to the Superior Court.
The PCRA court did not order Murchison to file a concise statement of errors
complained of on appeal.20 On June 25, 2020, the PCRA court issued an opinion
pursuant to Pa.R.A.P. 1925(a). The PCRA court changed its mind about the timeliness
of the petition but explained that the petition nonetheless failed on the merits.
In order to obtain relief on an after-discovered evidence claim under Subsection
9543(a)(2)(vi) of the PCRA based upon the results of the recent DNA testing, Murchison
was required to prove the following:
(1) the exculpatory evidence has been discovered after trial and could not have been obtained at or prior to trial through reasonable diligence; (2) the evidence is not cumulative; (3) it is not being used solely to impeach credibility; and (4) it would likely compel a different verdict.21
The PCRA court found that Murchison was unable to establish that the recent DNA testing
results were not cumulative or that they would likely compel a different verdict.
18 See Commonwealth v. Murchison, 294 A.3d 1251, 1258 (Pa. Super. 2023 (en banc) (quoting Commonwealth letter, 7/9/2019). 19 See Pa.R.Crim.P. 907. 20 See Pa.R.A.P. 1925(b). 21 Commonwealth v. Burton, 158 A.3d 618, 629 (Pa. 2017).
[J-74-2024] - 12 As for cumulativeness, the PCRA court found that none of the recent DNA test
results revealed anything new, and that they were cumulative of the evidence already
established at trial. With regard to the wooden slat, the PCRA court acknowledged that
the new DNA evidence excluded Murchison a contributor. The PCRA court observed that
the trial DNA evidence also had demonstrated that Murchison’s DNA was not on the
wooden slat, yet the jury had chosen to convict him. The PCRA court noted that the jury
also had been informed that Murchison was not one of the contributors of the semen on
the towel or blanket. According to the PCRA court, the only truly new evidence from the
new DNA testing “is that the DNA on Cannon’s sock came from Willis and an unknown
person.”22 At trial, the jury had learned that the DNA from Cannon’s sock came from
Willis, but it had not learned of the unknown person’s DNA.
The PCRA court found that none of the new DNA evidence was exculpatory and
that it would not have changed the outcome of the trial:
The fact that [Murchison’s] DNA was not found on these items, particularly the wooden slat, is meaningless and does not establish his actual innocence of killing Willis by strangulation. What renders it even more meaningless is that the jury was presented with this same evidence at trial— that [Murchison’s] DNA was not detected at the crime scene—and the jury still chose to find [Murchison] guilty of Willis’ murder. Furthermore, the medical examiner determined that Willis’s cause of death was manual strangulation, not trauma caused by the wooden slat. Thus, whether [Murchison] was excluded as a source of DNA on the wooden slat in no way establishes his actual innocence since the wooden slat was not even the murder weapon.23
The PCRA court was convinced that the jury convicted Murchison of Willis’ murder
not because of the DNA evidence but because Willis was strangled, because Thomas
22 PCRA Ct. Op., 6/25/2020, at 8. 23 PCRA Ct. Op., 6/25/2020, at 9-10 (emphasis in original, internal citation omitted).
[J-74-2024] - 13 placed Murchison near Willis’ house with a bag of stolen clothes, and because of
Murchison’s confessions to Hunt and Bowie. In light of the “overwhelming witness
testimony” presented at trial, the PCRA court concluded that the new DNA test results
would not likely compel a different result, and that no relief was due.24
On appeal, Murchison argued that he was entitled to relief because the new DNA
evidence revealed that someone—not him—left blood at the crime scene and touch DNA
on the wooden slat. Murchison asserted that this new evidence contradicted the
Commonwealth’s theory of the case and that, if that evidence had been introduced at trial,
the jury would have reached a different outcome. Murchison also argued that the PCRA
court applied the wrong legal standard when it evaluated this claim.
Initially, a divided three-judge panel of the Superior Court affirmed the denial of
PCRA relief. Murchison applied for reargument, which the Superior Court granted. Sitting
en banc, the Superior Court affirmed the PCRA court’s order in a divided, five-to-four
opinion.25 The Superior Court majority rejected Murchison’s arguments for the same
reasons offered by the PCRA court, and it supplemented the PCRA court’s analysis in
several respects. The Superior Court observed that, in comparison to the trial evidence,
the new DNA testing revealed that:
(1) testing of the wooden slat presented [Willis’] DNA, as well as the presence of trace DNA from an unknown contributor who could not have been [Murchison]; (2) there was the presence of a second, unknown contributor in the blood stain found on Cannon’s sock and [Murchison] was excluded as a contributor; (3) [Willis] was the source of blood detected on
24 PCRA Ct. Op., 6/25/2020, at 10. 25 Commonwealth v. Murchison, 294 A.3d 1251 (Pa. Super. 2023) (en banc).
[J-74-2024] - 14 Cannon’s boxer shorts; and (4) a fourth unknown contributor was found as to the semen stains on the blanket.26
The Superior Court viewed the new DNA testing as providing no substantial
change from the evidence that was introduced at trial except that Willis’ blood was
officially confirmed on Cannon’s boxer shorts and that Murchison was excluded as the
unknown contributor on the wooden slat. The fact that Willis’ blood was found on
Cannon’s boxer shorts was, according to the Superior Court, not surprising given
Cannon’s testimony that he attempted to wake Willis up by shaking her. There was also
evidence that Willis’ nose was caked with blood, that blood was coming out of her ear,
and that blood was on the floor. The Superior Court reasoned that the jury could have
inferred that Cannon got some of Willis’ blood on his clothing when he reached down and
touched her.
The Superior Court opined that, although the new DNA testing revealed the
presence of an unknown contributor on the wooden slat, “this cannot be viewed as
consequential concerning the outcome of the trial when looking at the other evidence.” 27
This other evidence included the fact that the official cause of death was manual
strangulation and the evidence that Willis allowed other drug-addicted individuals to use
drugs in her house, rented rooms to boarders, and engaged in prostitution in her house.
The presence of unknown contributors at the scene did not convince the Superior Court
that there may have been another perpetrator. The Superior Court emphasized the
testimony that put Murchison in the vicinity of Willis’ home around the time of the murder,
26 Id. at 1263. 27 Id.
[J-74-2024] - 15 that Murchison was observed to have significant scratches and injuries on his person,
and that he had confessed to killing Willis.
The Superior Court disagreed with Murchison’s argument that the PCRA court
applied the wrong legal standard to evaluate his after-discovered evidence claim.
Although the PCRA court referred to “actual innocence,” it did so only when it was
examining cases holding that “negative DNA results, meaning cases where a person’s
DNA material is not found, do not establish actual innocence.”28 The Superior Court
determined that the PCRA court’s statement did not go to the legal standard but, rather,
to the inferences that can or cannot be drawn from DNA test results.
Judge Olson authored a dissent (joined by Judges Dubow and Kunselman),
predicated on three bases. First, the dissent disagreed that the new DNA testing results
were cumulative of the trial evidence; contrary to the PCRA court’s findings, the jury at
the 2004 trial never learned that Willis was included as a contributor to the blood stains
found on Cannon’s boxer shorts and socks. Rather, the jury learned only that Willis could
not be excluded as a contributor. Judge OIson also observed that the PCRA court failed
to acknowledge that the new DNA testing of the wooden slat revealed trace DNA from an
unknown contributor, a fact that the jury never heard.
Second, the dissent believed that this new evidence was exculpatory and would
have changed the outcome of the trial had it been introduced. In particular, the dissent
opined that, had the jury heard that Willis’ blood was found on the boxer shorts of Cannon,
her occasional sexual partner, it would have connected Cannon to the murder. Similarly,
28 PCRA Ct. Op., 6/25/2020, at 9 (emphasis omitted) (citing Commonwealth v. Brooks, 875 A.2d 1141, 1147 (Pa. Super. 2005)).
[J-74-2024] - 16 the dissent believed that the new testing results confirming the presence of DNA from
unknown contributors in genetic material recovered from Cannon’s sock and the wooden
slat would “present a treasure trove of ammunition to a skilled trial advocate representing
a defendant who could not be connected by physical evidence to a particular offense.” 29
Third, the dissent opined that, in relying upon cases concerning a petitioner’s
threshold request for post-conviction DNA testing under Section 9543.1(c),30 the PCRA
court applied the wrong legal standard. Although petitioners seeking testing under
Section 9543.1(c) must make a prima facie demonstration that exculpatory results would
establish actual innocence, petitioners seeking relief under claims of after-discovered
evidence are not required to do so. The dissent believed that the PCRA court’s reliance
upon cases decided under Section 9543.1 resulted in the use of an irrelevant legal
standard in order to evaluate Murchison’s claim. For these three reasons, Judge Olson
would have awarded Murchison a new trial.
Judge Nichols also dissented, agreeing with Judge Olson that the PCRA court
applied an incorrect legal standard. Judge Nichols believed that this legal error warranted
vacating the PCRA court’s order and remanding for the PCRA court to reevaluate the
after-discovered evidence claim under the correct legal standard.
We granted Murchison’s petition for allowance of appeal in order to decide the
following issue:
Whether the Superior Court applied the correct standard for an after- discovered evidence claim based upon post-conviction DNA testing
29 Murchison, 294 A.3d at 1270 (Olson, J., dissenting). 30 Requests for post-conviction DNA testing require a prima facie showing that DNA testing of specific evidence, assuming exculpatory results, would establish the petitioner’s “actual innocence.” 42 Pa.C.S. § 9543.1(c).
[J-74-2024] - 17 received pursuant to Section 9543.1 of the PCRA and what value the jurisprudence related to a standard of actual innocence provides to that analysis.31
Murchison argues that the PCRA court held Murchison not to the burden of proving
an after-discovered evidence claim, but to the higher burden necessary to obtain post-
conviction DNA testing—actual innocence. According to Murchison, not only did the
PCRA court rely upon cases applying the actual innocence burden to requests for post-
conviction DNA testing, the PCRA court also twice held that Murchison failed to establish
his actual innocence. Murchison argues that the Superior Court wrongly endorsed this
approach.
Murchison argues that the lower courts failed to appreciate that the new DNA
evidence warrants relief because it is of a higher grade or character than what was known
at trial,32 failed to consider the significance of the new evidence to the Commonwealth’s
theory of the case,33 and failed to analyze whether the new evidence might lead a jury to
convict Murchison of a lesser degree of murder.
In its brief, the Commonwealth agrees with Murchison. The Pennsylvania
Innocence Project has filed an amicus curiae brief on behalf of Murchison, arguing that

Small, 189 A.3d 961, 975-76 (Pa. 2018) (holding that “evidence which is corroborative or cumulative, but not ‘merely’ so—that is, the new evidence is of a higher grade or character than what was previously presented on a material issue—may properly be used to support the grant of a new trial”). 33 See Commonwealth v. Bulted, 279 A.2d 158, 161-62 (Pa. 1971) (examining the emphasis that the district attorney placed on trial evidence in evaluating the significance of after-discovered evidence).
[J-74-2024] - 18 no state with a post-conviction DNA testing scheme requires proof of actual innocence in
order to obtain a new trial based upon post-conviction DNA testing.
As amicus curiae on behalf of the Commonwealth, the Attorney General argues
that the standard for after-discovered evidence is well-settled and is not in dispute in this
case. Further, according to the Attorney General, both of the lower courts correctly
applied this standard, and neither court required Murchison to establish actual innocence.
The real issue in the case, according to the Attorney General, is the application of the
after-discovered evidence standard to the facts presented. Examining these facts, the
Attorney General argues that the new DNA evidence, as well as the absence of
adversarial testing by the Commonwealth, is not likely to compel a different jury verdict.
In particular, according to the Attorney General, the blanket and towel only contained
irrelevant DNA; the DNA on the wooden slat was most likely the victim’s; the DNA on
Cannon’s sock was most likely from Cannon; and the jury already determined that the
blood on Cannon’s boxers was insignificant.
When we review the denial of PCRA relief, we inquire whether the PCRA court’s
findings are supported by the record and without legal error.34 Our review over questions
of law is de novo.35 Our “scope of review is limited to the findings of the PCRA court and
the evidence on the record of the PCRA court’s hearing, viewed in the light most favorable

[J-74-2024] - 19 to the prevailing party . . . .”36 The petitioner bears the burden to prove, by a
preponderance of the evidence, that he or she is eligible for PCRA relief.37
We agree with the Attorney General that there is no dispute among the parties or
among our precedents as to the standard applicable to an after-discovered evidence
claim. In seeking to demonstrate eligibility for relief under the PCRA, the burden of proof
is on the petitioner, who must make this showing by a preponderance of the evidence.38
For a claim of after-discovered evidence, the petitioner must show that the conviction
“resulted from . . . [t]he unavailability at the time of trial of exculpatory evidence that has
subsequently become available and would have changed the outcome of the trial if it had
been introduced.”39
In order to prevail under Section 9543(a)(2)(vi), a petitioner must prove that the
after-discovered evidence:
(1) could not have been obtained prior to the conclusion of the trial by the exercise of reasonable diligence; (2) is not merely corroborative or cumulative; (3) will not be used solely to impeach the credibility of a witness; and (4) would likely result in a different verdict if a new trial were granted.40
Several case-specific factors inform the analysis of whether the petitioner has
established by a preponderance of the evidence that the after-discovered facts would

Fahy, 959 A.2d 312, 316 (Pa. 2008). 37 42 Pa.C.S. § 9543. 38 42 Pa.C.S. § 9543(a) (“To be eligible for relief under this subchapter, the petitioner must plead and prove by a preponderance of the evidence all of the following: . . . .”). 39 42 Pa.C.S. § 9543(a)(2)(vi). 40 Commonwealth v. Pagan, 950 A.2d 270, 292 (Pa. 2008); see also Small, 189 A.3d at 972; Commonwealth v. Cox, 146 A.3d 221, 228 (Pa. 2016).
[J-74-2024] - 20 likely produce a different result. In Bulted, for example, the Court reviewed all of the trial
evidence, as well as the Commonwealth’s closing argument, in order to assess the impact
of the after-discovered evidence.41 In Commonwealth v. Mount,42 the Court analyzed
the impact of the after-discovered evidence against the Commonwealth’s theory of the
case. In Commonwealth v. Cooney,43 the Court held that after-discovered evidence
entitled the petitioner to relief because it supported and confirmed the petitioner’s trial
testimony and rendered the defense theory much more plausible.
This precedent demonstrates that the only way to assess the likelihood that after-
discovered evidence will produce a different result is to review the totality of all of the trial
circumstances, including, but not limited to, the trial evidence and the parties’ closing
arguments. When the petitioner establishes by a preponderance of the evidence that the
new facts are “of such a nature and character that a different verdict will likely result if a
new trial is granted,” then the petitioner is entitled to relief.44
In contrast, the “actual innocence” standard is a necessary component of Section
9543.1, which authorizes post-conviction DNA testing “for the purpose of demonstrating
the applicant’s actual innocence and not to delay the execution of sentence or
administration of justice.”45 Section 9543.1(c)(2)(i) requires the petitioner to make a

Valderrama, 388 A.2d 1042, 1045 (Pa. 1978) (holding that the after-discovered evidence provided substantial support for the defendant’s alibi defense and that a different verdict would likely result). 45 42 Pa.C.S. § 9543.1(a)(4).
[J-74-2024] - 21 sworn statement asserting actual innocence.46 Section 9543.1(c)(3) requires the
petitioner to establish a prima facie case that, assuming exculpatory results, the DNA
testing would establish actual innocence.47
This standard requires reviewing courts to evaluate the extent to which the
petitioner’s assertions demonstrate a prima facie case of actual innocence. Several
Superior Court cases have held that, when the petitioner believes that the DNA testing
will reveal the absence of the petitioner’s DNA at the crime scene, such negative DNA
test results do not necessarily establish the petitioner’s actual innocence.48 However,
once the petitioner obtains the DNA testing and new evidence is discovered, there is no
dispute that Section 9543.1(f)(1) directs the petitioner back to the provisions governing
the eligibility for relief for claims of after-discovered evidence.49
A claim of after-discovered evidence based upon post-conviction DNA testing
obtained under Section 9543.1 does not require proof of actual innocence. This is

Super. 2005) (holding that the petitioner’s prima facie case for the significance of the absence of his DNA from the victim’s fingernails failed because “even if DNA testing were to generate the result that [the petitioner] anticipates—absence of his DNA from the victim’s fingernails—this would not establish his innocence of her murder”); Brooks, 875 A.2d at 1147 (holding that DNA test results would not establish actual innocence because “[t]his is not a rape-murder case where the absence of the defendant’s semen could prove his innocence; or a case where there were signs of a struggle and the perpetrator left behind skin, hair, or blood samples”); Commonwealth v. Heilman, 867 A.2d 542, 547 (Pa. Super. 2005) (holding that negative DNA test results showing the absence of the petitioner’s DNA at the crime scene would not establish actual innocence because “an absence of evidence is not evidence of absence”). 49 42 Pa.C.S. § 9543.1(f)(1) (directing the petitioner to file a PCRA petition under Section 9543(a)(2)(vi) (pertaining to claims of after-discovered evidence)).
[J-74-2024] - 22 indisputable. The PCRA is clear, as is our precedent. The parties and their amici agree.
The standard of proof for a claim of after-discovered DNA evidence is the same as for
every other claim of after-discovered evidence.
This also is consistent with the reasoning of the Superior Court majority. Writing
for that majority, Judge, now Justice, McCaffery specified that the court was relying upon
the PCRA standards for after-discovered evidence in Section 9543(a)(2)(vi), and was not
requiring proof of actual innocence.50 The two dissenting opinions in the Superior Court
also reviewed the new DNA evidence under the standard of Section 9543(a)(2)(vi). The
Superior Court majority and the two dissenting opinions each applied the correct legal
standard for evaluating after-discovered evidence claims based upon post-conviction
DNA testing.
Murchison’s argument is directed at the PCRA court’s analysis. The PCRA court,
in recognizing that Murchison was raising an after-discovered evidence claim, noted that,
in order to prevail, Murchison had to prove that the evidence met the four requirements
articulated above. The PCRA court began its analysis by correctly invoking this
standard51 and ultimately ended the analysis by concluding that the standard was not
met.52 In reaching this conclusion, the court held that none of the after-discovered
evidence was likely to result in a different verdict because it was not exculpatory,
50 Murchison, 294 A.3d at 1261, 1264. 51 PCRA Ct. Op., 6/25/2020, at 8. 52 Id. at 10 (concluding that Murchison was “unable to show that his newer DNA testing results would likely compel a different verdict”).
[J-74-2024] - 23 explaining that “negative DNA results, meaning cases where a person’s DNA material is
not found, do not establish actual innocence.”53
While the PCRA court relied upon Superior Court cases applying the actual
innocence standard under Section 9543.1, it is clear to us that the court did so only as a
shorthand for evaluating whether the evidence, if produced at a new trial, would be likely
to result in a different verdict. In its citation to this standard and to the cases applying it,
the PCRA court was discussing the inference that could, or could not, be made from
negative DNA test results in light of the circumstances of the case, an inference that is
pertinent to assessing whether the after-discovered evidence likely would result in a
different verdict. The court did not import the actual innocence standard into this after-
discovered evidence analysis. Instead, the court merely assessed the impact of the after-
discovered evidence in the context of the unique circumstances of this case. Examining
the case that the Commonwealth presented against Murchison at trial, the PCRA court
concluded that Murchison was convicted because of the testimony against him, and that
the new DNA testing would not have compelled a different result.
Murchison’s after-discovered evidence claim failed in the courts below because
Murchison did not establish that the new DNA evidence was not merely corroborative or
cumulative of the trial evidence, nor did he prove that the new evidence would likely
compel a different verdict. The record supports the lower courts’ conclusions in this
regard. The new DNA testing discovered DNA from an unknown contributor on the
wooden slat, identified an unknown contributor to the DNA found on Cannon’s sock,
53 PCRA Ct. Op., 6/25/2020, at 9 (emphasis omitted) (citing Brooks, 875 A.2d at 1147 (holding that negative DNA results do not establish actual innocence)); Heilman, 867 A.2d at 547 (same); Smith, 889 A.2d at 586.
[J-74-2024] - 24 confirmed that Willis was the source of blood found on Cannon’s boxer shorts, and
identified a fourth unknown contributor to the semen stains on the blanket.
With respect to the wooden slat, the fact remains that Willis was killed by manual
strangulation. The slat was not a murder weapon. The absence of Murchison’s DNA on
the wooden slat is evidentiarily neutral: it neither implicates nor exculpates Murchison.
The presence of an unknown contributor on the wooden slat and the DNA in Cannon’s
sock fits within the trial evidence regarding the transitory nature of Willis’ home and the
several individuals who visited it and used the wooden slat to lock the front door.54 As
the Commonwealth argued to the jury, the lack of water and basic hygiene in Willis’ house
allowed for the presence of irrelevant DNA all over the crime scene. And the after-
discovered DNA evidence on the wooden slat and Cannon’s sock neither placed
Murchison at the scene of the crime nor excluded him.
The confirmation of Willis’ blood on Cannon’s boxer shorts also was addressed at
trial by the Commonwealth’s evidence that Cannon, believing Willis to be asleep and
unable to see clearly in the dark room, shook Willis’ blood-covered body to wake her up.
54 As amicus, the Attorney General asserts that the trace DNA newly discovered on the commonly touched wooden slat was a single allele, and the testing showed that it could have been Willis’ DNA. The Attorney General also argues that the wooden slat was known to have been touched by many people, and the fact that the touch DNA was limited to a single allele demonstrates that the wooden slat did not absorb DNA as well as other materials might, proving only that not everyone who touched the wooden slat left their DNA behind, including the person who used the wooden slat to beat Willis. As for Cannon’s sock, the Attorney General explains that the after-discovered DNA evidence could have come from Cannon himself: “When Cannon found Ms. Willis’ body, he had presumably been wearing that sock all day—possibly longer. It would not seem surprising to find his sweat or skin cells, which could now be tested for DNA in the material of his sock. What is surprising is that the newly discovered DNA was not compared to Cannon—the most likely contributor.” Amicus Brief of Attorney General at 33 (emphasis omitted).
[J-74-2024] - 25 From this testimony the jury could have inferred that Willis’ blood got onto Cannon’s
clothing.
The semen on the blanket and towel is irrelevant. This was not a sex crime. The
Commonwealth did not tie Murchison to Willis sexually or through an allegation of sexual
assault. Willis was known to prostitute herself for drugs and money, and the jury learned
at trial that Murchison was excluded as a source of DNA on the towel and the blanket.
When he confessed to Hunt, Murchison also confirmed that this was not a rape or a sexual
assault. This was a fight over drug money.
The witness testimony that led the jury to convict Murchison is not undone by the
post-conviction DNA testing evidence. Thomas observed Murchison near Willis’ house
around the time of the murder, and Murchison stated that he had just left Willis’ house.
Bowie encountered Murchison around the time of the murder and saw that he had a black
eye and a busted lip. Murchison told Bowie that he had been in a fight and had hit a
woman with a wooden stick. Murchison confessed to Hunt that he had beat and strangled
Willis because she “came back short.”55 Murchison explained that the two had gotten into
an argument about money, that the argument turned physical, that Murchison punched
and choked Willis, that Willis passed out several times, and that Murchison strangled
Willis and struck her with a wooden stick. Murchison also corrected Hunt’s incorrect belief
that Willis had been raped.
Taken together, the record supports the PCRA court’s conclusion that the after-
discovered DNA evidence does not demonstrate that a different outcome would be likely.
The order of the Superior Court is affirmed.
