At least six people were shot, one fatally, Thursday morning on the campus of Saugus High School in Santa Clarita, prompting a massive response from sheriff's deputies and paramedics, authorities said.
In a tweet, Sheriff Alex Villanueva said the suspected shooter was "in custody and being treated at a local hospital."
A Los Angeles County Fire Department spokesperson confirmed firefighters responded before 8 a.m. to the school at 21900 Centurion Way. One of the victims was struck in the stomach. Fire officials said six victims were transported from the scene. In a tweet, Henry Mayo Hospital said it had received four patients.
A hospital spokesperson later said a female victim was pronounced dead. Two male patients were in critical condition, while a third male was in good condition.
