Police were looking for witnesses on Wednesday after a triple-shooting near a high school campus in the West Los Angeles area left one person dead, police said.
Gunfire erupted at 9:03 a.m., police said. Officials found victims in the 8900 block of West Helms Place and in the 3100 block of South Helms Place, said Katherine Main of the LA Fire Department.
Police described a man wearing dark clothing, "carrying a gun and chasing victims through the neighborhood." Aerial video showed several patrol vehicles along Helms Place, just off the Santa Monica (10) Freeway.
It wasn't clear how many people the police were searching for because the victims were "not cooperating with police."
