LONG BEACH, Calif. (AP) — A Southern California hotel cook who threatened to shoot up his workplace and kept an arsenal at his home has been sentenced to three years and eight months in prison.

Thirty-seven-year-old Rodolfo Montoya pleaded no contest earlier this month to two felony counts of making criminal threats.

Police said Montoya,who worked at the Long Beach Marriott, was angry over a workplace issue and in August told a co-worker he was going to shoot other colleagues and people at the hotel. The co-worker notified management, who called police.

At Montoya's home, investigators found a Colt AR-15 rifle, a shotgun, pistols and other rifles, tactical gear and hundreds of rounds of ammunition, prosecutors said.

Montoya had “clear plans, intent and the means to carry out an act of violence,” Long Beach Police Chief Robert Luna said at the time.
