Opinion

[J-1-2017] [MO: Saylor, C.J.] IN THE SUPREME COURT OF PENNSYLVANIA EASTERN DISTRICT

COMMONWEALTH OF PENNSYLVANIA, : No. 727 CAP

Appellee : Appeal from the Order entered on May : 25, 2016 in the Court of Common Pleas, : Berks County, Criminal Division at No. v. : CP-06-0006003-2002.

: SUBMITTED: January 9, 2017 MICHAEL PRUITT,

Appellant

DISSENTING OPINION

JUSTICE WECHT DECIDED: June 20, 2017 I share the learned Majority's view that there is arguable merit in Michael Pruitt's

challenge to the effectiveness of his trial counsel, and that counsel could have had no

reasonable strategic basis for failing to investigate, to understand, or to rebut the

Commonwealth's presentation of DNA evidence at trial. I part ways with the Majority in

regard to the analysis of prejudice. Unlike the Majority, I conclude that Pruitt suffered

prejudice from his trial counsel's manifest dereliction, because there exists a reasonable

probability that, but for that dereliction, the jury would have been left with reasonable

doubt as to Pruitt's culpability for rape and involuntary deviate sexual intercourse

("IDSI").

Regardless of any concomitant impact upon Pruitt's conviction for first -degree

murder, acquittal of those felony sexual offenses would have been likely to alter the

ultimate outcome of the proceedings, in that the jury may have assigned lesser weight

to the sole aggravating circumstance that it found during the penalty phase-that Pruitt killed Greta Gougler while in the perpetration of a felony. See 42 Pa.C.S. § 9711(d)(6).

Identification and exploitation of weaknesses in the Commonwealth's forensic

evidence-and recognition that the Commonwealth's expert overstated the strength of that evidence at trial-could have raised a reasonable doubt regarding Pruitt's guilt of

these heinous sexual offenses, and, in turn, weakened substantially the

Commonwealth's capital case at the penalty phase. It follows that there is a reasonable

probability that counsel's failure to challenge the DNA evidence made the difference

between a sentence of life imprisonment and a sentence of death. As this was

"sufficient to undermine confidence in the outcome of the proceeding,"1 so as to

establish prejudice, I conclude that Pruitt's trial counsel was constitutionally ineffective.

Accordingly, I respectfully dissent.

I. The DNA Evidence

Pruitt was convicted of first -degree murder, robbery, burglary, rape, and IDSI. To

prove the sexual offenses, the Commonwealth presented evidence relating to the

testing of genetic material that was recovered from Greta Gougler's inner thigh. Full

comprehension of Pruitt's claims regarding this evidence requires a brief description of

the testing methodology and the conclusions that may be drawn from that testing.

"DNA is genetic material found in most types of cells of the human body,

including white blood cells and cells contained in semen and hair follicles."

Commonwealth v. Blasioli, 713 A.2d 1117, 1119-20 (Pa. 1998). DNA is organized in

twenty-three pairs of chromosomes, with one half of each pair inherited from the mother

and the other half from the father. David H. Kaye, DNA Evidence: Probability,

Population Genetics, and the Courts, 7 HARV. J.L. & TECH. 101, 107 n.35 (1993). The

Commonwealth v. Laird, 119 A.3d 972, 978 (Pa. 2015).

[J-1-2017] [MO: Saylor, C.J.] - 2 functional components of DNA are groups of molecules known as "nucleotides," which

join in predictable pairs known as "base pairs" and, when organized in a particular

sequence, serve as a code for a specific biological trait. Blasioli, 713 A.2d at 1120.

What we refer to as a "gene" is a specific sequence of base pairs that is responsible for

the expression of an individual human characteristic. Id. "Genes are the functional

units of the DNA molecule." JUSTICE MING W. CHIN ET AL., DNA BIOLOGY, FORENSIC DNA

EVIDENCE: SCIENCE AND THE LAW § 2:2 (2017 ed.) (hereinafter "CHIN"). Each gene may

be found at a particular "locus," which "represents a specific physical location of a gene

on a chromosome." Kimberly Cogdell Boies, Misuse of DNA Evidence Is Not Always A

"Harmless Error": DNA Evidence, Prosecutorial Misconduct, and Wrongful Conviction,

17 TEX. WESLEYAN L. REV. 403, 408 (2011) (hereinafter "Boies").

Most of a person's DNA is identical to that of every other person, with only

approximately three million out of a total of three billion base pairs varying between

individuals. Blasioli, 713 A.2d at 1121. These variations are called "polymorphisms,"

and they serve as the basis for DNA identification. Id. A particular variation is known as

an "allele," an "alternative form of a gene that can occupy a particular chromosomal

locus." Boies at 408 (quoting United States v. Chischilly, 30 F.3d. 1144, 1153 (9th Cir.

1994)). An allele also may be described as a "specific pattern of base pairs at a given

location on a given chromosome." CHIN at § 2.2. Because individuals inherit genetic

material from both parents, there are exactly two alleles at any given polymorphic locus

on any given set of complementary chromosomes. Id. One allele comes from an

individual's mother, and the other comes from the individual's father.

Most commonly, DNA testing is conducted through the identification of alleles by

analyzing repeating sequences of base pairs at a particular locus, called "short tandem

repeats" ("STR"). Comparison of DNA samples involves the identification of STRs at

[J-1-2017] [MO: Saylor, C.J.] - 3 standardized, designated loci on certain non -coding areas of the DNA strand. These

areas are not responsible for the expression of any particular biological trait, but

nonetheless contain allelic variations that can be compared to a sample of DNA from a

known source. CHIN at §§ 2.2, 2.3.

The variability of STR patterns between people is due to the fact that while every person has short repeating sequences of base pairs at the loci used for forensic identification . the number of repeats differs. For example, . .

at a particular locus, a person may have inherited 12 repeats from her mother and 14 repeats from her father. STRs are "short" because they are only two to six chemical letters long, "tandem" because they are on adjacent chromosomes, and "repeat" because the pattern repeats. One would say that this person's alleles at that locus are "12,14." A person may receive the same allele from both mother and father at a locus, resulting in a "homozygous" allele pairing of, for example, "16,16." A locus where the two alleles differ is called "heterozygous," for example, "12,14."

Inforensic DNA laboratory reports, a homozygous locus is often indicated with a single number, e.g., "16." When two DNA profiles are compared side -by-side, a match means that the DNA could have come from the same source, a determination that is informed .. by the statistical rarity of .

the DNA profile at issue.

Id. at § 2.3.

Although the term "match" often is employed when comparing the results of STR

analysis, the "more accurate description is that the individual is 'included' as opposed to

`excluded.'" Boies at 413. Using the above example of possible allele pairings, if

testing of Sample A and Sample B reveals an allele pairing of "12, 14" at a given locus
