Elsewhere in Southern California, police say they thwarted a mass shooting by a disgruntled cook at the Long Beach Marriott hotel who allegedly threatened to come into work to shoot everyone he saw. Long Beach Police Chief Robert Luna says officers found an arsenal of deadly weapons when they arrested 37-year-old Rodolfo Montoya at his home on Tuesday.

Police Chief Robert Luna: “Suspect Montoya had clear plans, intent and the means to carry out an act of violence that may have resulted in a mass casualty incident. A search of the suspect’s residence in the city of Huntington Beach led to the seizure of multiple high-powered firearms, hundreds of rounds of ammunition, as well as tactical gear, including an assault rifle and high-capacity magazines, which are illegal to possess in the state of California.”

The police were tipped off by a co-worker to whom the potential shooter spoke. There have been at least 30 arrests of people alleged to be planning massacres since the mass shootings in El Paso, Texas, and Dayton, Ohio, earlier this month.
