While Flores was arrested in three of the killings, the teen was arrested in one of them, police said.
Flores “admitted to killing her children,” the police statement said. But it was not immediately known whether she had a lawyer who could speak on her behalf. Online jail records showed she was detained on $6 million bail, with no court date set yet.
Prisila Canales, who lives near the ranch-style house in the West Hills neighborhood where the killings happened, told reporters there was a disturbance late Saturday night in which the woman screamed and acted erratically until someone called authorities.
Canales said paramedics put the woman on a stretcher and that she struggled and yelled, “Where's my Bible?”
