Colorado College Student Arrested After Police Find 'Large Cache' of Weapons on Campus

A college student in Colorado was arrested Tuesday after police discovered that he was allegedly making threats towards the university and was in possession of a "large cache of loaded weapons."

The Pueblo County Sheriff's Office identified the student as 24-year-old Robert James Killis. The sheriff's office said that Killis attended Colorado State University Pueblo.

"The Pueblo County Sheriff's Office is the law enforcement agency responsible for the CSU Pueblo campus," the sheriff's office said in a press release on Wednesday.

Deputies were recently notified that Killis allegedly made "threatening and concerning statements" toward staff and students at CSU Pueblo.

Witnesses told the sheriff's office that Killis, "who has previous military experience," would talk about purchasing "body armor, semi-automatic rifles, shotguns and other guns." The sheriff's office also said that witnesses reported Killis also allegedly saying that he enjoyed killing people.

Detectives first began monitoring Killis, who resided in an off-campus apartment on Monday, and they located his 2020 Chevy Silverado parked on campus. They noticed that Killis had an ammunition box, a bulletproof vest, and "a case that appeared large enough to hold a rifle or shotgun," inside his vehicle.

A day later, detectives with the sheriff's office executed a search warrant of Killis' residence and truck and detained him at a nearby restaurant.

According to the sheriff's office, Killis admitted that he had weapons inside his truck. When detectives conducted their search of the vehicle, they found "a loaded semi-automatic rifle, a shotgun and a handgun."

"There were also several fully loaded high-capacity magazines set up in a tactical manner along with an ammunition box filled with additional rounds of ammunition," the sheriff's office said. "Assorted tactical equipment also was located in the vehicle."

While executing the search warrant at his apartment, detectives found another handgun with roughly 100 rounds of ammunition.

Killis was arrested for unlawfully carrying or possessing a weapon on a university campus, said authorities.

Pueblo County Sheriff Kirk M. Taylor praised those who came forward with information on Killis.

"By reporting suspicions to our deputies in a timely manner," said Taylor, "we were able to quickly investigate and take this person into custody before any harm could be done."

The sheriff continued: "Out of an overabundance of caution, there will be an added law enforcement presence at the university and our deputies will be available to address any concerns from students and faculty...We continue to encourage anyone who sees or hears anything suspicious or threatening that involves an educational setting to report it immediately."

Newsweek was directed to the press release after reaching out to the Pueblo County Sheriff's Office for comment.
