BOSTON » A man fatally shot in an armed domestic confrontation with police was a hometown friend of actor Mark Wahlberg, who helped him get small movie roles.

Wahlberg and Paul Campbell, whose mother was found dead, had been friends in Boston’s Dorchester neighborhood, The Boston Globe reported Campbell had a scene in "The Fighter" as a crack addict acting out a legendary boxer’s moves in the ring. He had bit roles in "Ted" and "American Hustle."

Police said they were called Monday to the Weymouth house Campbell shared with his mother and fired shots when they found him in an agitated state, holding at least one knife. They found his mother’s body on the steps, apparently stabbed.

Neighbor Peter DeLuca told the Globe that Campbell said last week he was going to California to get into acting but needed to get the money to go.

The Globe said court records showed that Campbell, 49, had a history of arrests for drug possession, drunken driving and assault and that his defense attorney said in a 1997 filing he had a heroin addiction.

Wahlberg, 43, is seeking a state pardon for a 1988 assault on two Vietnamese men for which he served a brief jail sentence. He says he has turned his life around in his career and charitable work.

Campbell had a relationship with Mayor Martin Walsh’s girlfriend two decades ago and was her daughter’s father. Walsh issued a statement requesting privacy for the family.

The police shooting is under routine review by prosecutors.
