Colorado police are investigating a murder after a man was caught trying to break into a Colorado Springs police station Sunday morning to surrender.

Carlos Trejo, 36, was arrested after he allegedly tried to break into a police substation shortly before 1:30 a.m., KMGH reported. He reportedly told police he’d shot and killed his roommate and wanted to turn himself in.

Officers responded to Trejo’s nearby apartment and found a dead man  inside.

Police said Trejo has been charged with second degree murder.

The roommate’s identity has not been released, and police released no other information about the incident.

A neighbor reported to KKTV hearing yelling and screaming Saturday afternoon

“It’s funny because not only did I hear the yelling and screaming at like 2:00, 3:00 yesterday, I also heard banging on the walls around 6:30, 7:30, and somebody saying ‘I’m done, I’m done, I’m done,’ and that’s pretty much what it led up to until 1:30 this morning, cops knocking on my door and everyone else on the floor,” the neighbor said.

According to jail records, Trejo is being held on a $50,000 bond and is due in court on Monday.
