The victim turned to run, but one of the men pulled a gun and shot him in the back, Wendell said. Both men then fled.

The shooting was reported to authorities by staff members at Scripps Mercy Hospital at about 9 p.m. Sunday, when the victim walked into the emergency room, Wendell said.

The police department's Gangs Unit investigated the shooting, she said.

SAN DIEGO -- An 18-year-old man suffered a gunshot wound to the back in a shooting in Logan Heights, San Diego police said Monday.

Two men with shaved heads walked up to the victim in the 1800 block of Kearny Avenue Sunday and asked him where he was from -- a common way gang members ask each other about their respective gang affiliations, said Sgt. Diane Wendell.
