A Dorchester man has been convicted of killing a Randolph man in a shooting that unfolded in the parking lot of Boston Bowl in September 2019.

Brian Joyce, 30, was found guilty of first-degree murder by a Suffolk County jury after six hours of deliberation on Friday, according to DA Kevin Hayden's office.

The victim was Marcus Dunn-Gordon, 27, who was shot to death on September 16, 2019 after he and a group of friends were involved in what prosecutors called a "verbal altercation" inside the bowling alley and pool hall.

"Dunn-Gordon and his friends decided to leave without escalating the conflict any further and walked out of Boston Bowl. Joyce and his friends followed them outside and confronted Dunn-Gordon and his friends in the parking lot," according to an account from Hayden's office. "A physical fight ensued and Joyce pulled out a firearm and shot Dunn-Gordon. Dunn-Gordon ran across the parking lot and collapsed inside the lobby of the Ramada Inn. He was transported to a local hospital and pronounced dead."

Joyce, who was on probation at the time of the murder after a conviction for armed robbery, was wearing a GPS monitoring device when the shooting took place. He and his friends fled the Morrissey Boulevard scene in a white SUV and another car.

Joyce will be sentenced on November 22 at 9 a.m. by Judge Mark Hallal, according to the DA.

“Marcus Dunn-Gordon tried to do the right thing that night by leaving Boston Bowl to avoid further confrontation with Brian Joyce," said Hayden. "But Joyce made the terrible decision to follow Marcus out to the parking lot. He confronted Marcus again, pulled out a gun and shot him to death. I thank the jurors for their deliberation and verdict, and I offer Marcus’s family and friends my deepest sympathies."
