Police arrested Montoya last year after he threatened a coworker in the kitchen of the Long Beach Marriott at 4700 Airport Plaza Drive, according to authorities.
Rodolfo Montoya’s arrest sparked national attention in August when authorities said they’d likely averted a mass shooting.
Police allege the suspect “had the motive, means, and intention to carry out a mass shooting of employees and guests at the Long Beach Marriott Hotel.”
Before he was taken into custody last month, the cook told a coworker about his step-by-step plan to shoot up his workplace, according to the warrant.
Prosecutors said Montoya had an AR-15 assault rifle and numerous other weapons stashed in the RV where he lived.
Officers found high-powered firearms, hundreds of rounds of ammo, tactical gear, assault rifles and high capacity magazines when they searched the Huntington Beach home of Rodolfo Montoya on Tuesday, said police.
Domingo was arrested April 22 after authorities say an undercover informant worked with the FBI to foil the plot.
He could face life in prison if he’s convicted of providing material support to terrorists and attempted use of a weapon of mass destruction
The FBI details multiple instances where undercover operatives apparently attempted to guide Domingo away from a spur-of-the-moment shooting.
The Army veteran accused of plotting a terrorist attack in Long Beach was demoted and discharged from the military for a serious offense.
