PARIS – Judge Roland A. Cole on Monday sentenced the last defendant in a brutal Otisfield assault last fall, ordering him to spend six months behind bars.

Peter G. Berube III, 24, of 11 Market Square in Paris was convicted of Class C assault. He was sentenced to four years in prison with all but six months suspended.

Berube will also serve a two-year probationary period, be required to pay $1,225 in fines, and $2,642 in victim restitution fees.

The incident took place on Sept. 9, 2006, when Berube, Justin Rolfe, 22, of 19 Edgerly Lane in Oxford, and Tony Kimball, 22, of 34 High St. in Paris attacked a man at a gathering in Otisfield. The victim said he did not know the three men and that the attack was unprovoked. He suffered a collapsed eardrum, broken nose and other internal facial injuries, records state.

According to a police affidavit, Kimball’s girlfriend said Rolfe yelled at the man for looking at her and later sucker-punched him. As Rolfe repeatedly punched him, Kimball and Berube were hitting him in the head and body, the girlfriend said.

Rolfe was ordered to serve four years of a 10-year state prison sentence in January, with a four-year probationary period. Kimball was sentenced Friday to 364 days in county jail, of which he will serve 30 days.

Rolfe’s criminal history includes at least four convictions as a juvenile and adult, including charges of assault and burglary.

Berube also has a prior record of violence. On Aug. 6, 2001, he was convicted of two counts of assault in 11th District Court in Paris.

He was arrested two days after the attack by Trooper Andre Paradis of the Maine State Police Department. Though he was arraigned on a Class B assault, and indicted in October on a Class A assault, the severity of the charge was lowered as part of a plea bargain.
