A man in his 30s was killed and three other men injured in a shooting Sunday morning in Roslindale, according to Boston police.

The shooting occurred at about 3 a.m. in the area of 784 Canterbury St., police said in a statement.

The man in his 30s was pronounced dead at the scene, according to the statement, and the other victims, all in their 20s, suffered non-life-threatening injuries.

Police did not identify any of the victims, and the conditions of the survivors were not released.

Authorities said the man who was killed was known to police.

Boston police spokesman Officer James Kenneally said investigators believe a party was held at the Canterbury Street address Saturday evening.

It was not clear how many shooters were involved, and no arrests were made as of Sunday evening.

The driveway of the home was sealed off with police tape Sunday afternoon.

A police cruiser was parked in front of the two-story, beige-colored home, and an officer said no one was inside.

One neighbor, who declined to give her name, said the street is normally quiet and she does not know the residents of the home at 784 Canterbury St. or the shooting victims.

“It was shocking,” she said of the news.

The listed owner of the home did not return a message seeking comment.

The slaying on Sunday was the city’s 31st homicide of the year, compared to 34 at this time last year, Kenneally said.
