Disgruntled cook had arsenal of guns, threatened mass shooting at Long Beach Marriott hotel, police say

A California hotel cook who was upset over a work-related human resources issue was arrested after he threatened a mass shooting and stored guns and ammunition at his home, police said.

Authorities said Rodolfo Montoya, 37, told a co-worker he was going to shoot fellow employees and guests at the Long Beach Marriott. The co-worker told the hotel's general manager who reported the matter to police.

Police arrested Montoya on Tuesday at his Huntington Beach home.
