The suspect's body was found inside the van which authorities said he used to flee after attempting a second shooting on Sunday. The man, who died of a self-inflicted gunshot wound after a standoff with police some 34.5 kilometers from the scene of the shooting, was described by local police as an "Asian male", but not much more is as of yet known about him.

Los Angeles County Sheriff Robert Luna said there was no other suspect at large, as the man is thought to have acted alone.

In a news conference early on Monday, Luna said the motive for the shooting remained unclear. He had previously stated that police could not rule out that the attack was racially motivated.
