PA Supreme Court: Trial Court May Not Consolidate Separate Sexual Assault Cases Based Solely on “Similar” Allegations, and Rape Kits Are Testimonial Under the Confrontation Clause

Criminal Defense Lawyer Zak T. Goldstein, Esquire

The Pennsylvania Supreme Court has decided the case of Commonwealth v. Walker, holding that the trial court abused its discretion when it consolidated three separately-charged CODIS hit rape cases for a joint trial under the common plan, scheme, or design exception to the rule against propensity evidence.

The Court also held that the admission of rape kit reports without testimony from the nurse examiners who actually prepared them violated the defendant's constitutional right to confrontation. This is a landmark decision that significantly tightens the standard for when the prosecution may try separate offenses together and provides important new protections for defendants in sexual assault cases.

The Facts of Commonwealth v. Walker

In July of 2019, the defendant was arrested and charged with the rape of three different women on three separate occasions — P.C. in January of 2011, T.A. in December of 2014, and B.H. in January of 2015. Each complainant underwent a sexual assault examination after the attack, and DNA from the perpetrator was recovered and uploaded to the Combined DNA Index System (CODIS). In December of 2018, a CODIS search revealed that the male DNA samples from all three victims matched, and that DNA profile was later linked to Walker.

In each case, the defendant met the victim, a stranger, on a public street in Philadelphia, convinced her to follow him to a secluded area, and then sexually assaulted her. However, the specific details of each assault varied significantly. In one case, the perpetrator used a knife; in another, he punched the victim in the face; in the third, he struck the victim with a tire iron. He robbed only one of the three victims. One rape occurred near midnight while the other two occurred during the late morning. Each assault took place in a different Philadelphia neighborhood.

The Commonwealth moved to consolidate all three cases for a joint trial, arguing that the evidence of each assault would be admissible at a trial for the others because the assaults shared sufficient similarities to establish a common plan, scheme, or design. Despite the defendant’s objection, the trial court granted the Commonwealth's motion.

Prior to trial, the defendant also filed a motion in limine seeking to preclude the Commonwealth from introducing the rape kit reports prepared by the sexual assault nurse examiners at the Philadelphia Sexual Assault Response Center (PSARC) for two of the three victims. The Commonwealth acknowledged that the nurses who actually performed the examinations no longer worked at PSARC. Instead, the prosecution planned to introduce the reports through the testimony of PSARC's nurse manager and clinical director who did not personally conduct any of the examinations. The trial court denied the defendnat’s motion.

At trial, the defendant was convicted on numerous charges including rape, involuntary deviate sexual intercourse, and sexual assault. He was sentenced to an aggregate of 28 to 56 years' imprisonment and classified as a Tier III sex offender with lifetime registration under SORNA. The Superior Court affirmed, and the Supreme Court granted allowance of appeal.

The Supreme Court's Ruling on Consolidation

The Pennsylvania Supreme Court reversed, finding that the trial court abused its discretion in consolidating the three cases. Under Pennsylvania Rule of Criminal Procedure 582, separate offenses may be tried together only if the evidence of each offense would be admissible in a separate trial for the other. The key question was therefore whether evidence of the other rapes would have been admissible under the common plan, scheme, or design exception to Pennsylvania Rule of Evidence 404(b), which generally bars the prosecution from introducing evidence of a defendant's other bad acts to show criminal propensity.

Critically, the Court took the opportunity to reshape the law on this issue. Over the years, Pennsylvania courts had applied an increasingly diluted version of the common plan, scheme, or design exception. What started as a narrow exception, requiring either a true overarching plan linking crimes together or a modus operandi so distinctive as to be a signature, had devolved into a vague “logical connection” test that merely required “sufficient similarities” between the crimes. The Court recognized that this relaxed standard effectively gutted Rule 404(b)’s core protection against propensity evidence.

Writing for the majority, Justice McCaffery abrogated the “logical connection” test and returned to the original two-pronged framework from Shaffner v. Commonwealth, 72 Pa. 60 (1872). Going forward, the Commonwealth may consolidate separately-charged offenses under the common plan, scheme, or design exception only where it can establish either: (1) the offenses constitute “signature crimes,” meaning the facts are so unique and distinctive that they must have been committed by the same perpetrator; or (2) the offenses were linked to achieve a common goal, meaning the bad acts are part of an integrated plan to accomplish a specific objective.

Applying this newly clarified standard to the defendant’s case, the Court found that neither exception was satisfied. First, the three rapes did not qualify as signature crimes. While all three involved stranger assaults, the specific details varied considerably. The perpetrator used different weapons (or none at all), initiated contact differently, and committed the assaults in different neighborhoods at different times. These were, as the Court put it, characteristics typical of any stranger rape case, not a unique signature. Second, there was no evidence of a preconceived plan linking the three crimes together to achieve a common goal. The evidence simply showed that the perpetrator raped women when presented with the opportunity to do so. A general desire to commit the same type of crime is not the kind of common plan or scheme that Rule 404(b) contemplates.

The Court also emphasized an important procedural point. The decision to consolidate cases is made pretrial, before the defendant has revealed any defense strategy. The Commonwealth cannot justify consolidation based on its anticipatory rebuttal of a defense, such as a consent defense, that the defendant has not yet raised. A defendant has no duty to present evidence and may instead rely on the presumption of innocence and the Commonwealth's burden of proof.

The Supreme Court's Ruling on the Rape Kit Reports

The Supreme Court also ruled in the defendant’s favor on the Confrontation Clause issue. The Sixth Amendment and Article I, Section 9 of the Pennsylvania Constitution guarantee criminal defendants the right to confront the witnesses against them. In a line of cases including Crawford v. Washington, Melendez-Diaz v. Massachusetts, Bullcoming v. New Mexico, and most recently Smith v. Arizona, the United States Supreme Court has made clear that the Confrontation Clause applies to forensic reports and that the prosecution may not introduce testimonial hearsay, including forensic reports, without providing the defendant an opportunity to cross-examine the person who actually prepared the report.

The Pennsylvania Supreme Court held that rape kit reports are testimonial in nature. The reports are formally titled “Sexual Assault Forensic Examination Forms,” and the very word “forensic” signals their evidentiary purpose. The reports were created primarily to establish past events and collect evidence relevant to a potential criminal prosecution, not simply to provide medical treatment. The Court also noted that Pennsylvania statute explicitly defines a rape kit as a “sexual assault evidence collection kit,” and the law requires health care facilities to notify law enforcement of the alleged assault.

Because the rape kit reports were testimonial and were offered for their truth at trial, the Confrontation Clause required the testimony of the nurse examiners who actually prepared them. The testimony of PSARC’s clinical director, who did not personally perform any of the examinations, was not an adequate substitute. The Court rejected the Commonwealth's argument that the reports were admissible under the medical records or business records exceptions to the hearsay rule. Hearsay exceptions cannot override the Confrontation Clause. When an out-of-court statement constitutes testimonial hearsay, it may not be admitted at trial unless the defendant had the opportunity to cross-examine the declarant, regardless of whether the statement would otherwise qualify as a hearsay exception.

The Takeaway

Commonwealth v. Walker is one of the most significant Pennsylvania Supreme Court decisions in recent years for criminal defendants. On the consolidation issue, the Court meaningfully strengthened the protections of Rule 404(b) by rejecting the watered-down “logical connection” test and demanding that the Commonwealth meet a real standard before it can try separate cases together. This matters because consolidation is enormously prejudicial. A jury hearing about multiple allegations is far more likely to convict on all of them than a jury considering each charge independently. Going forward, the prosecution will need to show either a true signature crime or a genuine common plan linking the offenses together, rather than simply pointing to broad similarities between different cases.

On the Confrontation Clause issue, the decision provides a clear rule for sexual assault cases: the prosecution must produce the actual nurse examiner who prepared the rape kit report, or it cannot introduce the report. This prevents the Commonwealth from relying on a “surrogate witness” who simply reads the absent nurse’s report into the record.

Defense attorneys handling sexual assault cases, cases involving motions to consolidate, or cases involving the admission of forensic reports should take note of this decision and use it to protect their clients’ rights.
