Long Beach police are looking for whoever shot a man to death in Central Long Beach on Monday night, officials said.

At around 7:40 p.m. officers responded to a call of a shooting on Rose Avenue near 14th Street, police said. When they arrived, officers found a man lying in the courtyard of an apartment complex with gunshot wounds to his upper torso, according to a news release from the department.

Bystanders attempted performing “life-saving measures” on the victim until they were relieved by the responding officers who requested paramedics, police said. Long Beach Fire Department personnel responded to the scene and transported the victim to a local hospital where he later died from his injuries, according to authorities.

At this time, officials only identified the victim as a man. The Los Angeles County Coroner’s office will release more information after notifying his next of kin.

Police cannot confirm the exact motive for the shooting, but officials said they are investigating it as gang-related, which means they believe it was committed “for the benefit of, at the direction of or in association with any criminal street gang.”
