CARTHAGE — A local man is accused of threatening another man with a BB gun last week at a West Side Road residence in Carthage.

Maine State Police Trooper Andrew Hardy arrested Spencer C. Knox,  26, of Carthage on a charge of terrorizing. After review of the charge by the District Attorney’s Office, it was changed to criminal threatening. He is being held on a probation violation.

Knox pleaded guilty in March 2018 in Franklin County Superior Court in Farmington to arson and violation of release for a connected case. He was sentenced to serve 20 months of a five-year sentence, followed by four years probation for burning his father’s truck in December 2017. A second charge of arson and charges of aggravated criminal mischief and tampering with a witness, informant, juror or victim were dismissed in a plea agreement.

He is still on probation for that case.

Hardy responded Jan. 27 to a report of an armed robbery in Carthage and met with a man who alleged Knox robbed him. Illegal drugs and a conflict over a woman were involved in the case, according to Hardy’s affidavit filed with a Farmington court.

Several state troopers and Franklin County deputies surrounded a residence in Carthage and Knox came out without incident and was questioned. The BB was found under a blanket on the couch. Initially, the BB gun was thought to be a handgun, according to the affidavit.

Knox was arrested and taken to the Franklin County Detention Center in Farmington.

On Friday, Knox pleaded not guilty to the threatening charge. A  judge set bail at $500 cash or personal recognizance and a supervision agreement. A probation hold was still in place.

On Monday, Knox denied violating probation. A judge set bail on the probation violation at personal recognizance and a supervised agreement. He was released from jail Monday.

A conviction on a threatening charge carries up to 364 days in prison and a maximum $2,000 fine.
