SANTA CLARITA, Calif.—A Los Angeles County firefighter appeared to have a longstanding job-related dispute with the colleague he shot and killed at their small, rural fire station in what became California’s second deadly workplace shooting in less than a week, authorities said Wednesday.
The gunman also wounded a fire captain at the station about 45 miles north of Los Angeles on Tuesday before setting his house on fire in a nearby community and apparently killing himself, officials said.
