A former middle school aide from Contra Costa County has found himself at the center of federal charges involving the receipt and possession of child sexual abuse material, as announced by US Attorney Craig H. Missakian and Homeland Security Investigations Acting Special Agent in Charge Jeffrey Brannigan yesterday. Dominic James Vannucci, 25, from Discovery Bay, made his initial federal court appearance today after being indicted by a grand jury last week, according to documents released on the U.S. Attorney's Office for the Northern District of California's website.
The indictment alleges that Vannucci received materials depicting the sexual abuse of a minor in May 2025, and it is further alleged that he possessed similar illicit content involving a prepubescent minor from an unspecified date through June 2025, where the indictment does not provide a concrete starting point for when Vannucci may have begun amassing the troubling content. Vannucci, who until recently worked at an unnamed East Bay middle school, faces up to 20 years in prison and a $250,000 fine for each count if convicted on these charges.
While the indictment is an accusation and not proof of guilt, it lays out potential maximum and minimum sentences that hinge on the outcome, as determined by the federal court system. Vannucci's conditional release suggests a possibly complicated case ahead, with a status conference scheduled for September 19, before US District Judge Jon S. Tigar.
This case comes from a collaborative effort by Homeland Security Investigations, the Contra Costa County Sheriff's Office, and the Contra Costa County District Attorney's Office. Assistant U.S. Attorney Kelly I. Volkar prosecuted with the aid of Alycee Lane and Amala James. Those with related information are urged to contact HSI at [email protected] or (877) 477-4847.
