Prosecutors say that a man who was arrested on Monday after allegedly threatening to shoot people at a college campus was part of a "conspiracy."

The 27-year-old man from Norco, California, Jacob Ryan McBain, was arrested for allegedly making threats to shoot people at a local college campus, and was found to have a loaded AR-15 gun in his bedroom.

On Monday morning, the Riverside County Sheriff's Department launched an investigation after being alerted to the series of threats made by McBain, which he shared on his Facebook page, said Lieutenant Eric Briddick, according to NBC Los Angeles.

Investigators searched the man's apartment with a warrant, according to Desert Sun, and court reports state McBain had a loaded AR-15 with 510 rounds of ammunition and two loaded handguns.

"That is still under investigation," spokesman for the Riverside County District Attorney's office John Hall said. "The co-conspirators have not yet been identified."

McBain's full charges include nine felonies: conspiracy to commit a crime; two counts of criminal threats of death or great bodily injury; two counts of convicted felon and narcotic addict in possession of a firearm; three counts of illegal firearm possession; and one count of possession of an assault weapon.

Investigators reviewed McBain's Facebook page and found that he had an interest in guns, particularly the AR-15. The National Rifle Association refers to the AR-15 as the most popular rifle in the United States. It's one of the most popular weapons of choice for mass killers.

McBain is being held in lieu of $500,000 bail at the Robert Presely Detention Center and will be making his first court appearance on Thursday, according to NBC Los Angeles.

His roommate he had "no idea" about McBain making any threats, according to NBC Los Angeles.

"He is not a bad guy," McBain's roommate said. "He is young and stupid."
