SAN DIEGO — Police tracked down a suspect and arrested him in a nearby backyard after a fatal shooting near a Lincoln Park trolley platform, authorities said.

The shooting happened just after 7 p.m. at the 47th Street Trolley Station. Officers swarmed the area when they found a 44-year-old man shot and bleeding profusely. They attempted CPR on the victim, who has not been publicly identified, but he soon was pronounced dead at the scene.

In the nearby Chollas View neighborhood, residents flagged down officers and pointed them to the backyard of a home, police Lt. Matt Dobbs said. Officers told FOX 5 a man was observed jumping fences in the area.

Video from OnScene.TV shows six armed officers with a police dog arresting a man at that home as a police helicopter shines a light down on him, lying in the grass surrendering.

The man, also not identified, was taken to police headquarters to be interviewed, Dobbs said. Police said he was 34 and the victim was 44 years old.

“A firearm was recovered here at the scene and we’re in the process of identifying evidence and interviewing witnesses at this time,” he said.

Other details including what led to the shooting were not immediately known. Witnesses told police there may have been some kind of fight leading up to the gunfire.
