HAMPDEN, Maine — Police were investigating an unrelated matter at the home of a convicted felon last week when they learned he had purchased a weapon, Hampden Police Chief Joe Rogers said Tuesday.

Harry J. Coffin II, 40, “had possession of a firearm,” the chief said. “He had purchased it through a private sale.”

The handgun allegedly owned by Coffin, who is barred from possessing weapons because he is a felon, was taken as evidence. He was arrested by Officer Marc Egan at around 9 p.m. Nov. 30, and taken to the Penobscot County Jail.

Coffin has a number of convictions on his record, according to prior Bangor Daily News court listings. He was convicted in 1991 for operating motor vehicle after suspension and since then has racked up convictions for offenses including terrorizing, theft by unauthorized taking, unlawful possession of scheduled drug, violating his conditions of release, burning prohibited material, allowing a dog to be at large, failing to appear after bailed and forgery, the BDN listings state.
