LA County off-duty firefighter who killed coworker had 'some workplace beef'

Authorities said that a Los Angeles County firefighter who opened fire at Station 81 had a longstanding job-related dispute with the colleague he shot and killed, according to the Associated Press. The gunman, who was identified Wednesday by the coroner's office as Jonathan Tatone, was off-duty when he showed up at the Agua Dulce fire station Tuesday and shot two of his coworkers. The second gunshot victim was a fire captain at the station. Authorities said the shooter left the firehouse after the attack and led authorities to his home in Acton, where he set his house on fire and apparently killed himself, officials said.
