A shooting outside a house party in Hacienda Heights on Saturday night left three teens wounded, officials said.
The gunfire was first reported about 9:30 p.m. in the area of Armington Avenue and Garo Street, Los Angeles County Sheriff's Department Lt. James Long said. It was believed to be related to a nearby party.
A 15-year-old boy was found seriously wounded at the scene and taken to a hospital for treatment, the lieutenant said. He was hospitalized in critical but stable condition early Sunday morning, officials said.
The other two victims, a boy and girl who were 16 and 17 years old, suffered wounds not believed to be life threatening, Long said. The wounded boy was found at the scene, while the girl was taken to a hospital by a private vehicle.
Witnesses initially described the attackers as four males in a silver or grey, four-door sedan, sheriff's officials said.
An exchange of words preceded the shooting, he said. The motive was unclear as the investigation continued Saturday night.
