This from LA Now:
A security guard working night patrol at the Adventure City amusement park shot and killed a man who had hit him in the head.
The shooting took place at the intersection of Beach Boulevard and Starr Street in Stanton at about 11 p.m. Tuesday, authorities said. The security guard was patrolling the perimeter of the theme park, which is geared toward families and young children.
The guard approached a man in a pickup truck who had stopped at the park’s service entrance, and they began fighting with each other. The man allegedly struck the security guard on the head with “some type of blunt-force instrument,” said Orange County sheriff’s spokesman Jim Amormino.
Amormino said the man then allegedly retrieved an object from his truck “that was at least a couple feet long” that the security guard mistook for a shotgun. The man advanced toward the security guard, and the guard shot the man multiple times, he said. The man was pronounced dead at the scene.
