COLUMBUS, Neb. -- Columbus Police responded to a person falling outside and ended up making a first-degree murder arrest on Sunday afternoon.

On Sunday, just before 4:20 p.m., the Columbus Police Department and Columbus Fire responded to a call for a person who reportedly fell outside of 1305 8th Street. 

Columbus Police Captain Douglas Molczyk said on Monday that the initial report was that a person had fallen and had a bump on his head. 

Molczyk said that when Columbus PD officers arrived, they spoke to the person who fell, eventually identified as 28-year-old Michael Keener. 

Officials said that while officers were talking to Keener, he told them that he had killed a person at another location. 

CPD said Keener took officers to the second location in the 200 block of 16th Avenue of Columbus.

Molczyk said officers found a dead 77-year-old man at the scene. Officers eventually identified the man as Larry Houdek.  

Officials said they found items that belonged to Houdek on Keener. 

Keener was arrested by Columbus Police officers for first-degree murder and use of a deadly weapon to commit a felony. He was taken to the Platte Detention Facility, and he remains in custody as of Monday morning.

This is an ongoing investigation.
