The Pennsylvania Superior Court handed down three precedential sex-offense decisions on April 10, 2026 — Commonwealth v. Mancuso, Commonwealth v. Rivera, and Commonwealth v. Smith. Each case raises distinct issues, but together they paint a picture of the kinds of problems that recur in sexual-assault prosecutions: vague charging documents, the risks of trying co-defendants together, the consequences of winning an appeal only to face a harsher sentence, and the ongoing effort to define the boundaries of Pennsylvania’s unlawful-contact-with-a-minor statute. The most significant of the three is Mancuso, which offers the most detailed Devlin analysis the Superior Court has produced in years.
Mancuso: When “Sometime During This Year” Isn’t Good Enough
The Setup
Three brothers — Damien, Sean, and Rian Mancuso — were tried together for sexual offenses against a single complainant, B.P. The allegations stemmed from incidents that occurred when B.P. was a teenager and frequented a business called Adventure Games in Lackawanna County. Sean owned the business. B.P. reported the incidents to police in October 2019 — well over a decade after they allegedly occurred.
Each brother faced different charges based on different alleged conduct at different times. Sean was accused of forcing B.P. to perform oral sex on him when she was fourteen, in 2003 or 2004. Rian was accused of pulling up B.P.’s skirt and pressing his face to her genital area, also when she was fourteen, around the same time. Damien was accused of forcing B.P. to perform oral sex on him in a deserted parking lot roughly two years later, when she was sixteen.
Following a three-day trial, all three brothers were convicted. Damien received 5 to 10 years, Sean received 96 to 194 months, and Rian received 6 to 12 months. All three appealed.
The Superior Court reversed or remanded on every brother’s case — but for different reasons.
Damien’s Due Process Claim: The Devlin Problem
The heart of the opinion is Damien’s due process challenge under Commonwealth v. Devlin, 333 A.2d 888 (Pa. 1975).
Here’s the core principle. The Due Process Clause — both the federal version under the Fourteenth Amendment and the state version under Article I, Section 9 of the Pennsylvania Constitution — requires that a criminal defendant receive fair notice of the charges against him. That notice has to be specific enough that the defendant can actually prepare a defense. When the Commonwealth can’t pinpoint the date of an offense, it must at least fix the date with “reasonable certainty.” If it doesn’t, the defendant is left trying to defend against an allegation that could have happened on any day within a broad window — and that’s a problem, because you can’t mount an alibi defense when you don’t know which day you need an alibi for.
Devlin established this principle in 1975. The defendant there was accused of sodomy against a victim with significant mental impairment. The only evidence at trial was that the crime occurred “sometime” within a fourteen-month period. The Supreme Court reversed, holding that a fourteen-month window was too broad. It violated due process because the defendant couldn’t meaningfully prepare a defense — he couldn’t pursue an alibi, couldn’t challenge the complainant’s credibility with specificity, and couldn’t pin down the circumstances surrounding the alleged event.
In the decades since Devlin, courts have carved out a degree of flexibility for cases involving young children. When a victim is very young — a five-year-old, a six-year-old — courts have recognized that kids don’t track dates the way adults do. They don’t know whether something happened on a Tuesday or a Thursday, or in March versus May. In those cases, courts have held that the Commonwealth can satisfy Devlin by fixing the beginning and end of an ongoing course of abuse, even without nailing down specific dates within that range.
But the Mancuso court drew a clear line. Those cases are different from Damien’s situation. B.P. was sixteen at the time of the alleged assault — not a young child. She was “long past childhood,” as the court put it, and should have been able to identify some anchoring detail: the season, whether school was in session, a birthday, even the weather. She didn’t. She testified that it happened on a “normal” day. She could describe what Damien’s car looked like, what he said, and where the parking lot was — but she couldn’t provide anything that would narrow the one-year window in the amended information.
The Commonwealth tried to rescue its case with the testimony of a friend, Dustin Siniawa, who said Damien bragged about having sex with B.P. in late 2005 or early 2006. But the court was unimpressed. Even construing this testimony favorably, it only compressed the window to “approximately half a year at best,” which the court found still spanned “too many months to establish the date of the offense with sufficient particularity.”
The court methodically distinguished every post-Devlin case the Commonwealth relied on — Groff, G.D.M., Sr., Niemetz, Renninger, Benner, Jette, K.E.N. — and showed that each one involved either a young child, an ongoing course of abuse, or the Commonwealth’s presentation of other evidence that narrowed the timeframe. None of those features were present here. It was a single alleged assault against a teenage victim who was old enough to remember temporal details, and neither the complainant nor any other witness provided them.
The opinion is worth reading in full for defense practitioners who handle Devlin issues. It’s the most thorough treatment of the Devlin framework — and its limits — that the Superior Court has produced in some time.
Rian’s Severance Claim: Guilt by Brotherhood
While the court reversed Damien’s conviction on due process grounds alone, it reached the central issue in Rian’s appeal: whether the trial court should have severed Rian’s case from Damien’s.
The framework here comes from Pennsylvania Rules of Criminal Procedure 582 and 583. Rule 582 permits joinder of defendants when the charges arise from “the same act or transaction or in the same series of acts or transactions.” Rule 583 allows severance when a defendant would be prejudiced by a joint trial. The court found that joinder of Rian and Sean was proper because their alleged offenses occurred on the same day as part of a connected chain of events — Sean’s conduct was intertwined with Rian’s in time and place. But Damien’s offense was entirely separate: different location, different type of conduct, two years apart.
The court relied heavily on Commonwealth v. Hamilton, 303 A.3d 823 (Pa. Super. 2023) — a case our office litigated on appeal. In Hamilton, the court held that severance was required even where there was some overlapping evidence between the joined cases, because the irrelevant evidence from one case was prejudicial to the defendant’s defense in the other. The same principle applied here. Joining Rian’s trial with Damien’s exposed the jury to testimony about Damien’s offense that had nothing to do with Rian and served only to smear him.
The prejudice was compounded by the Commonwealth’s closing argument. The prosecutor called the three brothers “three aggressors,” argued that B.P. had to come forward because “they still have the store” and “they still had power over other people,” and likened them to organizations like the Catholic Church and Boy Scouts — institutions known for harboring abusers. The prosecutor also suggested that the three defense attorneys were “ganging up” on the complainant during cross-examination. All of this invited the jury to treat Rian as guilty because his brothers were accused of similar conduct. That’s exactly the kind of guilt-by-association prejudice that severance is supposed to prevent.
The court granted Rian a new trial and, for good measure, held that Siniawa’s testimony — about Damien bragging about B.P. — was irrelevant to Rian’s charges and should be excluded on remand.
Sean’s Appeal: A Merger Issue
Sean’s convictions were affirmed, but the court found a sentencing error. The trial court failed to merge Sean’s convictions for involuntary deviate sexual intercourse (known as IDSI — essentially forced oral or anal sex) and indecent assault for sentencing purposes. Because both convictions arose from the same act — B.P.’s testimony that Sean forced her to kiss his penis — the lesser offense of indecent assault should have merged into the IDSI conviction. Sean’s case was remanded for resentencing.
Rivera: The Risk of Winning an Appeal
Commonwealth v. Rivera, 2026 PA Super 68, is a cautionary tale about one of the less-discussed risks of criminal appeals.
Jonathan Rivera was convicted of multiple sex offenses against four minor girls in Bradford County. After his first trial in 2019, he received an aggregate sentence of 8 to 52 years. He appealed, and the Pennsylvania Supreme Court found constitutional errors and granted him a new trial.
So far, a success story for the defense. But here’s what happened next.
At the second trial in April 2024, Rivera was convicted again on all eleven charges. The same judge who presided over the first trial also presided over the second. And at the second sentencing hearing, the court imposed a harsher sentence: 10 years and 3 months to 64 years — an increase of more than two years on the minimum and twelve years on the maximum.
Rivera raised a vindictive-sentencing claim under the framework established by the United States Supreme Court in North Carolina v. Pearce, 395 U.S. 711 (1969). The idea behind Pearce is that due process forbids punishing a defendant for exercising appellate rights. When the same judge imposes a longer sentence after a retrial, a presumption of vindictiveness attaches. To rebut that presumption, the court must point to “objective information” that justifies the increase — things like new conduct by the defendant after the original sentencing, or legitimate sentencing concerns that weren’t available the first time around.
The Superior Court found the presumption of vindictiveness applied — same judge, harsher sentence after a successful appeal. But it also found the presumption rebutted. The trial court had identified several new factors: Rivera’s designation as a Sexually Violent Predator (a determination that hadn’t occurred before the first sentencing), the victims’ more detailed testimony about the impact of the abuse (they were five years older at the second trial), and what the court described as Rivera’s “unconvincing, unbelievable and fabricated testimony at trial.”
This is one of those outcomes that defense lawyers have to think about honestly when counseling clients. Rivera won his appeal. He got a new trial. And he ended up with a sentence twelve years longer on the back end. The law provides protections against vindictive sentencing, but those protections have limits — especially after Alabama v. Smith, 490 U.S. 794 (1989), and Commonwealth v. Prinkey, 277 A.3d 554 (Pa. 2022), which narrowed Pearce‘s presumption considerably. When a retrial produces new information that the court didn’t have the first time — even information about the same underlying conduct — the court has room to resentence more harshly.
Rivera also raised an ex post facto challenge to his felony corruption-of-minors conviction, arguing that the version of Section 6301 under which he was sentenced didn’t take effect until December 2010, after the offenses involving that complainant. The court found the issue unpreserved but reached the merits anyway because ex post facto claims implicate the legality of the sentence. On the substance, the court concluded there was record support for finding that at least some of the abuse occurred after the statute’s effective date, and the jury was free to credit that evidence.
The judgment of sentence was affirmed.
Smith: Applying Strunk to Unlawful Contact with a Minor
Commonwealth v. Smith, 2026 PA Super 69, returns to the Superior Court after a remand from the Pennsylvania Supreme Court. The question is a focused one: whether the evidence was sufficient to sustain Smith’s two convictions for unlawful contact with a minor under 18 Pa.C.S.A. Section 6318, in light of the Supreme Court’s 2024 decision in Commonwealth v. Strunk, 325 A.3d 530 (Pa. 2024).
Strunk clarified the scope of Section 6318. That statute — sometimes described as an anti-grooming law, though imperfectly — doesn’t criminalize the physical act of sexually assaulting a child. Other statutes do that. Section 6318 targets the communicative conduct that precedes or facilitates the assault. In Strunk, the Supreme Court reversed a conviction because there was no evidence the defendant communicated with the victim to further the assaults — the victim was asleep or feigning sleep during each incident.
On remand, the Superior Court applied Strunk and found the evidence against Smith sufficient. Unlike in Strunk, Smith made several verbal statements to the victims. He told one victim to lick his penis. He told the other to get onto a table immediately before sexually assaulting her. These verbal requests placed the victims in positions that facilitated the assaults. The court held that these communications — verbal directions designed to further the sexual exploitation of children — were exactly the kind of conduct Section 6318 is meant to reach.
The judgment of sentence was affirmed.
What These Cases Mean for Practitioners
Mancuso is the headline decision from this batch. For defense lawyers handling cases with vague date ranges — especially where the complainant was not a young child — the opinion provides a detailed roadmap for raising and preserving a Devlin challenge. It also reinforces the importance of severance motions when co-defendants face unrelated charges that happen to share a complainant. The court’s reliance on Hamilton confirms that overlapping evidence isn’t enough to justify joinder when the prejudice of a joint trial outweighs the convenience.
Rivera is a reminder that appellate success doesn’t always translate into a better outcome for the client. Defense attorneys should have frank conversations with clients about what a new trial means in practice — including the possibility of a longer sentence.
Smith is the ongoing effort to define Strunk‘s contours. The takeaway is that any verbal direction or communication that facilitates a sexual assault — even one spoken moments before the act — can satisfy Section 6318. The line between Strunk (no communication, conviction reversed) and Smith (verbal instructions to the victims, conviction affirmed) is becoming clearer with each new case.
