A Colorado State University Pueblo student who authorities say made threats towards staff and fellow students at the school was arrested on Tuesday after “a large cache of loaded weapons” and nearly 1,000 rounds of ammunition were allegedly found in his possession on campus.

Robert James Killis, 24, is suspected of unlawful carrying/possessing a weapon on a university campus. The offense is a low-level felony.

The Pueblo County Sheriff’s Office said Killis, who has military experience, would “talk about buying body armor, semi-automatic rifles, shotguns and other guns” and that he said “he liked to kill people.”

Authorities did not elaborate on the kinds of threats Killis allegedly made.

“I commend the information coming forward which we acted upon quickly,” Pueblo County Sheriff Kirk Taylor said in a written statement. “By reporting suspicions to our deputies in a timely manner, we were able to quickly investigate and take this person into custody before any harm could be done.”

The sheriff’s office is working on the case with local, state and federal law enforcement.

Taylor said there will be a greater law enforcement presence at the university out of an abundance of caution.

CSU Pueblo declined to comment on the case, but in a bulletin to its campus said that Killis is not permitted on the school’s grounds and is considered dangerous.

“If you see this person on campus, please call 911 immediately,” the bulletin said.
