New Haven Man Arrested for Violating Supervised Release
John H. Durham, United States Attorney for the District of Connecticut, and Brian J. Taylor, Acting United States Marshal, announced that GARY JOSEPH GRAVELLE, 51, of New Haven, was arrested today in New Britain by members of the U.S. Marshals Service Violent Fugitive Task Force and the New Britain Police Department on federal supervised released violation.
Gravelle appeared this afternoon before U.S. Magistrate Judge Robert M. Spector and was ordered detained.
According to statements made in court, Gravelle is under investigation for sending multiple threatening communications and for mailing multiple letters containing white powder to several federal and state offices, and community organizations, in September 2018.
On July 19, 2013, Gravelle was sentenced in Bridgeport federal court to 70 months of imprisonment, followed by three years of supervised release, for mailing numerous threatening letters. He was released from federal prison in November 2015. It is alleged that Gravelle failed to comply with certain conditions of his supervised release, including failing to notify the U.S. Probation Office of a change of residence, and failing to comply with a mental health treatment requirement.
U.S. Attorney Durham stressed that charges are only allegations, and the defendant is presumed innocent unless and until proven guilty beyond a reasonable doubt.
The investigation concerning the sending of threatening communications is continuing. Anyone with pertinent information is asked to call the FBI at 203-777-6311.
