A Jack in the Box employee died after he was shot Friday night by a masked man who attempted to rob the fast-food restaurant in El Monte, California.
The attempted robbery and shooting occurred at about 7:30 p.m. in the 9200 block of Flair Drive, said Lt. Mike Rosson of the Los Angeles County Sheriff's Department.
A man wearing a Halloween mask -- it was unclear what kind -- entered the restaurant, jumped the counter and shot a male employee before he ran off empty handed and fled in a car.
It was unknown how many times the robber fired his gun. Employees and patrons ran away when he started shooting.
The employee was taken to a local hospital, where he was pronounced dead. His identity was withheld pending family notification.
Detailed descriptions of the shooter and his vehicle were not immediately available.
Authorities plan to look through surveillance video, Rosson said.
