WILTON — An attorney who practices in Rumford is facing terrorizing charges related to bomb threats made to two Wilton schools in March.

The attorney, Ronald Hoffman, 52, was summoned Friday on two misdemeanor charges of terrorizing, acting district attorney Alan Kelley said.

Hoffman, of Sumner, had no obvious connection with the schools, according to Wilton Police Chief Heidi Wilcox.

On March 29, a man whose speech was described as slurred called in bomb threats to the Academy Hill and Cushing schools that led to the evacuation of the two buildings.

More than 360 children, between 3 and 12 years old, were bused to other schools, after which Maine State Police cleared the buildings without finding any suspicious devices.

The charges against Hoffman come as a result of an intensive investigation by the Police Department and the Major Crimes Division of the state police, according to Wilcox. A special agent from the FBI was also involved in the investigation.

The quick thinking of the school staff who took the calls helped give the investigation an early focus, Wilcox said.

“The receptionists did a fantastic job,” she said. “When they took the call, they thought to leave the phone off the hook. That helped us to track where the calls were coming from.”

Early in the investigation, Wilcox said, police conducted “a series of search warrants, mostly for digital information.”

Hoffman is scheduled to appear in Franklin County District Court on July 19. The two misdemeanor charges each carry a maximum penalty of 364 days in jail.

A receptionist at Hoffman’s office referred calls to the office of James Martemucci, a Portland-based attorney who practices criminal defense.

Martemucci is on vacation this week, and his office could not confirm that he will represent Hoffman in the case.

Hoffman graduated from the Massachusetts School of Law in 1996. He has acted as the defense attorney in several high-profile criminal cases, including that of Christian Nielsen, who is serving a life sentence for murdering four people in Bethel in 2006.
