A Michigan man was arrested on Monday on murder charges related to the fatal shooting of two people in a dormitory at the University of Colorado campus in Colorado Springs, the police said.

Nicholas Jordan, 25, of Detroit, who was enrolled at the university, was arrested in Colorado Springs on first degree murder charges in the shooting of another student, Samuel Knopp, 24, of Parker, Colo., and Celie Rain Montgomery, 26, of Pueblo, Colo., the Colorado Springs Police Department said on Monday in a series of statements on X.

Mr. Jordan was being held on $1 million bond in El Paso County jail and was scheduled to appear in court on Tuesday, records show.

The police said that the investigation was ongoing and that the people involved knew each other. They did not provide a motive or other details.

Mr. Knopp was a senior at the university studying music, and Mr. Jordan was also enrolled at the university, said Jenna Press, a university spokeswoman. She did not provide further details. The university’s music program in 2023 featured a video of Mr. Knopp playing his guitar during his junior recital.

At about 6 a.m. on Friday, the campus police received a call about gunfire coming from Crestone House, a dormitory on the campus of the University of Colorado at Colorado Springs, a city of about 480,000 people at the base of the Rocky Mountains.

The campus police found two people dead in the room and called the Colorado Springs Police Department, which dispatched its homicide unit to investigate.

By Friday night, the police had an arrest warrant, setting in motion a search for Mr. Jordan. By Sunday, the police department called the shooting “an isolated incident between parties that were known to one another and not a random attack against the school or other students at the university.”

The department said it was working with the campus police to ensure the campus community was safe.

The search lasted through the weekend, until about 8 a.m. on Monday, when a motor vehicle theft unit found Mr. Jordan in a car in the city, the police said. He was taken into custody after about 30 minutes.

Students and officials held a “healing walk” on campus on Monday, laying flowers at the base of a marble statue of a mountain lion, a symbol of the university and the mascot for its athletic teams.
