A federal jury in Bridgeport has convicted Mandel Bidone, 34, formerly of Bridgeport, for mailing a threatening communication. The announcement was made by David X. Sullivan, United States Attorney for the District of Connecticut.
Evidence presented at trial showed that in April 2022, while incarcerated in state custody, Bidone filed a civil complaint in U.S. District Court for the District of Connecticut against “Yale New Haven Inc.” and other defendants. He alleged he had undergone an illegal clinical trial administered by Yale University and sought compensatory and punitive damages. The court dismissed his complaint as frivolous in October 2022.
In March 2023, Bidone mailed another civil complaint to the U.S. District Court’s Clerk’s Office in New Haven. This handwritten complaint, sent across eight envelopes, repeated many previous allegations but also included threats. At the top of the first page within each envelope was some variation of: “If the District Court dismisses this case or looses (sic) any one of the pages of this complaint, Mandel Bidone will purchase an illegal firearm and discharge it on Yale’s campus aiming for the students and staff until his is gunned down.”
The investigation found that Bidone also sent letters to the City of New Haven, the New Haven Police Department, and a local news affiliate discussing his complaint and repeating his threat against Yale students and faculty.
David X. Sullivan stated: “This investigation has been conducted by the U.S. Marshals Service, with the assistance of the FBI’s Joint Terrorism Task Force, the Yale Police Department, and the New Haven Police Department.”
Mailing a threatening communication carries a maximum sentence of ten years in prison. Bidone remains detained pending sentencing.
