Appeals Court Vacates Manslaughter Conviction Over Substitute DNA Analysts: Commonwealth v. Pinney (AC 24-P-1472, September 2, 2026)

The Massachusetts Appeals Court vacated Frederick Pinney’s involuntary manslaughter conviction on September 2, 2026, ruling that the admission of DNA testimony from substitute analysts who relied heavily on the work of a nontestifying analyst violated his Sixth Amendment confrontation rights. The Commonwealth conceded the error and acknowledged it could not prove the violation was harmless beyond a reasonable doubt.

TayClair Moore was found dead in Pinney’s bedroom on March 23, 2014. Pinney was charged with first-degree murder. After a mistrial in his first trial, a jury convicted him of involuntary manslaughter in March 2023. He received a sentence of nine to ten years in state prison.

The Facts

On Saturday, March 22, 2014, Moore attended Holyoke Saint Patrick’s Day festivities with her boyfriend, Christopher Podgurski. Podgurski and Pinney worked together in construction and knew each other for several years. Days earlier, Podgurski and Moore had moved from Podgurski’s mother’s home into Pinney’s two-bedroom Springfield residence.

Podgurski testified that he and Moore spent hours drinking, using marijuana, and using cocaine before meeting up with Pinney. The defendant stated he was having an anxiety attack, prompting the group to retrieve a prescription bottle of lorazepam. Podgurski asked Pinney to drive Moore home at approximately 3:30 P.M., giving him cocaine in exchange.

Cell phone records showed communications between Moore and Podgurski that evening, including messages from Moore at 11:23 P.M. The records also reflected numerous outgoing calls to Podgurski during the same period. Podgurski testified his cell phone battery died shortly after the last time he spoke with Moore at approximately 10:30 or 11 P.M.

Podgurski testified that after leaving a bar at approximately 2 A.M. on Sunday, March 23, 2014, he visited a friend, smoked marijuana, and then drove to his mother’s residence and fell asleep at approximately 3:30 A.M. A friend, Robert Keitt, testified that he called Podgurski’s parents’ home at approximately 5 A.M. and heard Podgurski snoring in the background.

Cell phone records reflected several text messages that Pinney sent to Podgurski and Moore during the early morning hours of March 23, 2014. At 4:25 A.M., Pinney sent Podgurski a text message, followed one minute later by another message.

Discovery of Moore’s Body

Podgurski returned to the Springfield residence at approximately 11:30 A.M. on March 23, 2014. He found Moore’s cell phone and glasses in their shared bedroom. He could hear Pinney snoring in his bedroom. Podgurski gave differing accounts of what followed. In one version, he knocked on Pinney’s door and asked if he had seen Moore. From behind the closed door, Pinney said Moore got mad and left. After about fifteen to twenty minutes, Pinney opened the door with a knife in his hand.

Once the bedroom door was open, Podgurski saw a pair of brown legs at the bottom of the bed. He went outside to call police.

Police Captain Richard LaBelle responded at approximately 12:44 P.M. and found Pinney in the kitchen. He saw blood on the floor and superficial lacerations on Pinney’s arms and neck. Pinney told LaBelle that no one else was inside the home.

After additional officers arrived, police conducted a search. Because Pinney’s bedroom door was locked, officers forced entry and discovered Moore lying unclothed and unresponsive on the floor beside the bed. LaBelle noticed a green cord hanging off the headboard. Emergency medical technicians determined that Moore was deceased.

Two days later, police executed a search warrant and recovered half of a green electrical cord, as well as several belts and a drawstring, from a dresser drawer in Pinney’s bedroom.

Medical Evidence

Dr. Anna McDonald, a forensic pathologist, performed an autopsy. She testified that Moore’s injuries were concentrated in her head and neck area, including linear abrasions on the right side of her neck, petechial hemorrhaging on her lips and neck, hemorrhaging within her neck muscles, and hemorrhages on the back of Moore’s head. Based on these findings, Dr. McDonald concluded that Moore’s cause of death was asphyxia caused by ligature strangulation.

Dr. McDonald noted foamy secretions from Moore’s nose, which she testified are commonly seen in drug-related deaths. Toxicology testing revealed that Suboxone, cocaine, citalopram, marijuana, and alcohol were present in Moore’s system at the time of her death. Dr. McDonald nonetheless opined that Moore’s injuries surpassed any toxicologic evidence.

Dr. McDonald testified that if a cloth belt recovered from the defendant’s dresser drawer were folded a particular way, it could correlate potentially with the abrasions on Moore’s neck. She similarly opined that the drawstring could potentially correspond to Moore’s neck injuries.

Dr. Jonathan Arden, a forensic pathologist retained by the defense, disagreed with Dr. McDonald’s conclusions and testified that the medical findings were not definitive of fatal strangulation and were more consistent with mixed drug intoxication.

The DNA Evidence Problem

The Commonwealth presented DNA testing results through the testimony of two substitute experts, Kathleen Gould and Krista Lungren, employees of the Massachusetts State police crime laboratory. Both relied extensively on reports generated by Kira Snyder, a former crime lab employee who conducted the original DNA testing but did not testify.

Gould testified that a red-brown stain found below Moore’s right breast produced a DNA profile consistent with Pinney’s DNA profile, with an expected frequency of approximately one in 665 quadrillion unrelated individuals. She also testified that a swab of the green cord recovered from the headboard contained a mixed DNA profile that included Podgurski and excluded both Moore and Pinney. The DNA profile from scrapings of skin from under Moore’s left fingernails was also consistent with Podgurski’s profile and excluded Pinney.

Lungren testified about DNA profiles generated from the belts and drawstring recovered from Pinney’s dresser drawer. She testified that testing of the cloth belt contained a mixed DNA profile consistent with Moore and Pinney as possible contributors. Specifically, Lungren opined that it was 730 quadrillion times more likely that the DNA profile came from Moore and two unknown individuals than from three unknown individuals unrelated to Moore, and 4.7 million times more likely that one of the DNA profiles came from Pinney and two unknown individuals than from three unknown individuals not related to him. Testing of the drawstring similarly yielded a mixed DNA profile that was 550,000 times more likely to have come from Moore and two unknown individuals than from three unknown individuals unrelated to Moore.

What the Court Held

The Appeals Court first addressed Pinney’s sufficiency-of-the-evidence challenge. Pinney argued that the jury’s decision to convict him of involuntary manslaughter rather than murder demonstrated that they rejected the Commonwealth’s theory that Moore died from ligature strangulation. The court disagreed, finding that viewing the evidence in the light most favorable to the Commonwealth, the jury could have reasonably concluded that Pinney engaged in conduct involving a high degree of likelihood of substantial harm and that such conduct caused Moore’s death.

The court noted that cell phone records and Podgurski’s testimony permitted an inference that Pinney was alone with Moore during the time period when she died. Dr. McDonald’s testimony established that Moore died as a result of ligature strangulation. The jury could rely on forensic evidence linking Pinney and Moore to the belt identified as the likely instrument of death. The drop of Pinney’s blood found below Moore’s right breast further supports an inference of close physical contact between Pinney and Moore at or near Moore’s time of death.

The court also found that the jury’s involuntary manslaughter verdict did not necessarily mean they rejected the ligature strangulation theory. There was ample evidence from which the jury could have found that Pinney was significantly intoxicated and impaired at the time of Moore’s death. Based on that evidence, the jury could have concluded that the Commonwealth had failed to meet its burden to establish that Pinney was capable of forming the intent or knowledge to commit murder while nevertheless finding that he engaged in conduct that created a high degree of substantial harm.

The Confrontation Clause Violation

The court then turned to Pinney’s confrontation rights claim. At the time of trial, controlling precedent permitted substitute analyst testimony. However, while this appeal was pending, the Supreme Judicial Court ruled in Commonwealth v. Gordon that testimony from a substitute expert that depends on the truth of testimonial hearsay from a nontestifying expert violates the confrontation clause. The SJC stated that this result was dictated by the United States Supreme Court’s decision in Smith v. Arizona, and instructed that its holding applied prospectively and retroactively to those cases that were active or pending on direct review as of the date of the issuance of Smith.

The Commonwealth conceded that the testimony of the substitute analysts, Gould and Lungren, depended on the findings and report of the original analyst, Snyder, who did not testify. Accordingly, their testimony violated Pinney’s confrontation rights.

Why the Error Was Not Harmless

Because Pinney had preserved his objection at trial, the court evaluated whether the admission of the constitutionally proscribed evidence was harmless beyond a reasonable doubt. The court concluded it was not.

The testimony of the substitute analysts provided critical forensic support for the Commonwealth’s theory. The central issues at trial were whether Moore died from ligature strangulation and, if so, who caused her death. The challenged DNA evidence bore directly on both issues. Through the substitute analysts’ testimony, the Commonwealth established that a drop of blood recovered from Moore’s body matched Pinney’s DNA profile; that a belt identified as a potential ligature contained DNA consistent with both Pinney and Moore; that a drawstring identified as a potential ligature contained DNA consistent with Moore; and that Podgurski’s DNA was not on either item.

The Commonwealth emphasized the significance of the DNA evidence throughout trial. During his opening statement, the prosecutor expressly stated that DNA evidence would show that Pinney’s blood was found on Moore’s body, that DNA consistent with Pinney and Moore was found on a potential ligature, and that Podgurski’s DNA was absent from the belt and drawstring. The prosecutor made the same points during his closing argument, stressing that the DNA evidence was proof that Pinney, rather than Podgurski, killed Moore.

The DNA evidence also provided the most significant evidentiary corroboration of the Commonwealth’s theory, which otherwise relied principally on the testimony of Podgurski, whose credibility was subject to substantial impeachment. Evidence was presented that Podgurski testified pursuant to an immunity agreement and therefore had an incentive to minimize his personal involvement. The jury also heard evidence that Podgurski had strangled Moore on several occasions over the course of their ten-year relationship, suggesting a possible motive to deflect suspicion.

The court concluded it could not say beyond a reasonable doubt that the testimony of substitute analysts did not contribute to the verdict. Although the DNA evidence was not, by itself, dispositive of Moore’s cause of death or the identity of the person who caused it, it provided objective forensic corroboration of the Commonwealth’s theory of the case and directly countered the defense’s contention that Podgurski was the perpetrator. Given the significance of that evidence to the Commonwealth’s case, the prosecutor’s repeated emphasis on it during opening and closing arguments, and the shortcomings of Podgurski’s testimony, the properly admitted evidence was not so overwhelming that the erroneously admitted testimony could not have influenced the jury’s resolution of the contested issues.

Other Claims

The court addressed several other claims that are likely to recur in the event of a retrial.

Pinney argued that a second buccal swab obtained after the first was suppressed should have also been suppressed as fruit of the poisonous tree. The court disagreed. It found that the Commonwealth’s second motion to compel rested on separate evidentiary bases, including DNA profiles generated from other sources, results from a sexual assault evidence kit, the presence of both Pinney and Podgurski at the crime scene, the presence of wounds on both Pinney and Moore, and the presence of blood in common areas of the Springfield residence. Because the second buccal swab was obtained pursuant to a court order supported by independent probable cause, untainted by the prior illegality, the exclusionary rule did not require its suppression.

Pinney also argued that the trial judge erred in excluding a September 2015 email that the trial prosecutor sent to the Massachusetts Office of the Chief Medical Examiner. The court found no error. Although the email was not admitted in evidence, the trial judge permitted defense counsel to cross-examine Dr. McDonald about it. Having permitted cross-examination regarding the email, the judge could properly exclude the email itself. The court also noted that there was no evidence that Dr. McDonald relied on the email in forming her opinions, and she provided an independent evidentiary foundation for her conclusions.

Pinney argued that the trial prosecutor should have been disqualified and called as a witness because he failed to record interviews with Podgurski and sent the 2015 email to the medical examiner’s office. The court rejected this claim, finding that Pinney failed to show that the prosecutor had personal knowledge of relevant factors bearing on the credibility of other witnesses that could not be elicited by other means.

Finally, Pinney argued that the trial judge improperly denied his motion seeking the judge’s recusal. The court found this argument lacked merit. Pinney neither established that the trial judge failed to consider whether he could remain impartial under the circumstances, nor showed that a disinterested observer would reasonably believe that the judge’s impartiality may have been compromised.

Why It Matters

This decision follows the Supreme Judicial Court’s recent ruling in Commonwealth v. Gordon and applies it to vacate a manslaughter conviction. The case illustrates the practical impact of the confrontation clause in cases involving forensic evidence. When a substitute analyst testifies about testing performed by someone else, the defendant loses the ability to cross-examine the person who actually conducted the work. That loss can be decisive.

Here, the DNA evidence was not overwhelming, but it was critical corroboration in a case that otherwise rested heavily on the testimony of a witness with credibility problems. The prosecution emphasized the DNA evidence throughout the trial, and the jury likely relied on it to resolve the central question of who killed Moore. Without that evidence, or with the original analyst available for cross-examination, the outcome might have been different.

The court’s harmless error analysis is instructive. Even though other evidence supported the conviction, the Appeals Court refused to say beyond a reasonable doubt that the tainted DNA testimony did not influence the verdict. The decision underscores that harmless error review is searching, particularly where the challenged evidence goes to the heart of contested issues and provides scientific validation of the prosecution’s theory.

For practitioners, the case serves as a reminder that substitute analyst testimony remains viable only when the original analyst is unavailable and the defendant had a prior opportunity for cross-examination. The Commonwealth will need to make that showing if it retries Pinney.
