BUFFALO — A 32-year-old Colorado man who formerly attended Buffalo State College pleaded guilty today to transmitting interstate communications containing threats to injure the person of another. The charge carries a maximum of five years in prison, a fine of $250,000 or both.

Assistant U.S. Attorney Stephanie Lamarque, who is handling the case, stated that Benjamin Bolton, of Glendale, Colo., made numerous telephone calls to faculty and staff personnel employed at Buffalo State, and to officers of the Buffalo State University Police Department between June and August of 2015. During many of these telephone calls, Bolton threatened to assault police officers, faculty, and staff members whom he identified by name.

The plea is the culmination of an investigation by the Federal Bureau of Investigation, under the direction of Special Agent in Charge Adam S. Cohen and the Buffalo State University Police Department, under the direction of Chief Peter Carey.

Sentencing is scheduled for Dec. 19.
