A New York appellate court has upheld the conviction of William Bergeron for predatory sexual assault against a child and endangering the welfare of a child. The ruling, issued on November 13, 2026, by the Appellate Division of the Supreme Court of the State of New York, affirms a jury verdict that found Bergeron guilty of these serious crimes. This decision impacts the victim, the defendant, and the broader community by reinforcing the legal consequences of child sexual abuse.

The case stems from allegations that Bergeron, who was the live-in boyfriend of the victim's mother, engaged in repeated sexual acts with the victim from the ages of six to eight. The victim, who is now 11 years old, testified in court about the abuse, which she described in detail. The court's ruling emphasizes the importance of credible testimony from victims in sexual assault cases, especially those involving minors.

In this case, the victim's testimony played a crucial role in the prosecution's case. She provided specific details about the incidents, including descriptions of unique items used during the abuse that were found in the family home. The court noted that such evidence supports the victim's account and reinforces the jury's decision to convict Bergeron.

The legal dispute began when Bergeron was charged with predatory sexual assault against a child, a crime defined under New York Penal Law as engaging in sexual conduct with a child under the age of 13. The prosecution also charged him with endangering the welfare of a child, which can include actions that are likely to harm a child's physical, mental, or moral well-being.

The Appellate Division's ruling addressed several key arguments raised by Bergeron. He contended that the evidence presented at trial was insufficient to support the conviction and that the jury's verdict was against the weight of the evidence. However, the court rejected these claims, stating, "Viewing the evidence, including the victim's testimony, in the light most favorable to the prosecution, we conclude that there is a valid line of reasoning and permissible inferences that could lead a rational person to conclude beyond a reasonable doubt that... defendant engaged in two or more acts of sexual conduct with the victim."

The court also found that the victim's testimony was corroborated by the discovery of specific items during a search of the residence, which were used in the abusive acts. The judges noted that the jurors had the opportunity to assess the victim's credibility during the trial and believed her testimony. The ruling stated, "There is no basis in the record for us to substitute our credibility determinations for those of the jury."

Another point of contention for Bergeron was the time frame alleged in the indictment. He argued that the two-year period was overbroad and unreasonable. However, the court exercised its discretion to review this contention and concluded that the time frame was appropriate, as the law allows for a single offense to be characterized as a continuing crime over a significant period.

The court also addressed Bergeron's claims regarding ineffective assistance of counsel. He argued that his defense attorney failed to call a witness to rebut expert testimony regarding child sexual abuse accommodation syndrome (CSAAS). The court found that the defense counsel's decisions were reasonable given the circumstances and that Bergeron did not demonstrate how expert testimony would have changed the outcome of the trial.

Overall, the Appellate Division affirmed the lower court's judgment, stating that the sentence was not unduly harsh or severe. This ruling serves to reinforce the legal system's commitment to addressing child sexual abuse and protecting vulnerable victims.

The implications of this ruling extend beyond this individual case. It highlights the importance of believing and supporting child victims in sexual abuse cases. The decision may also influence future cases involving similar charges and the standards of evidence required for convictions in child sexual assault cases.

Looking ahead, Bergeron has the option to appeal the decision to a higher court, although details about any potential appeal were not available in the court filing. The case underscores the ongoing challenges faced by victims of sexual abuse and the legal system's role in ensuring justice is served.
