Oscar Valenciano Jr., 15

Oscar Valenciano Jr., a 15-year-old Latino teenager, was fatally shot Monday, Oct. 10, in the 8500 block of South Hoover Avenue in Vermont Knolls, according to Los Angeles County coroner's records.

The shooting occurred at Algin Sutton Park about 4:30 p.m. It sent dozens of children and adults scrambling for cover as the attacker, who was on a bike, pulled out a handgun and fired multiple rounds, said Deputy Chief Pat Gannon of the Los Angeles Police Department.

A bystander flagged down LAPD patrol officers and alerted them that the attacker had ditched his bike and taken off on foot, police said. A foot pursuit followed, and officers detained a suspect.

During the shooting, Valenciano was struck in the neck and abdomen. The two other victims were a 17-year-old girl shot in the back and a 19-year-old woman shot in the leg, the LAPD said. They did not suffer life-threatening injuries.

Anyone with information about the shooting is asked to contact the Los Angeles Police Department at (877) LAPD-24-7 (877) 527-3247. Those wishing to remain anonymous can call Crime Stoppers at (800) 222-TIPS (800) 222-8477.
