A South Dennis man has been sentenced for making threats against a federal official and their family members. Michael P. Mahoney, 62, received a sentence of two years of supervised release, including three months of home detention and a $5,000 fine. The sentencing was handed down by U.S. District Court Chief Judge Denise J. Casper.
Mahoney pleaded guilty in August 2025 to one count of transmitting interstate threats to injure another person. He was arrested and charged in April 2025.
The incident occurred on March 28, 2025, when the relative of a prominent federal official was dining with others outside Massachusetts. At around 10:15 p.m., the relative received a call from an unknown number. According to court documents, Mahoney confirmed the relative’s full name before shouting threats and using explicit language directed at the relative, their spouse, and the federal official by name. The call lasted about 12 seconds before being disconnected; Mahoney immediately called again but received no answer.
Investigators traced both calls to Mahoney through phone records obtained from the service provider. When law enforcement approached Mahoney at his residence in South Dennis on March 29, he did not respond to attempts to contact him.
The case was announced by United States Attorney Leah B. Foley; Ted E. Docks, Special Agent in Charge of the Federal Bureau of Investigation’s Boston Division; Colonel Geoffrey D. Noble of the Massachusetts State Police; and Dennis Police Chief John Brady. Assistant U.S. Attorney Jared Dolan prosecuted the case as Chief of the National Security Unit.
