The man accused of gunning down a tribal police officer in a remote corner of the nation's largest American Indian reservation has pleaded guilty to second-degree murder.
Kirby Cleveland faces a possible life sentence in connection with the death of Navajo Nation Officer Houston Largo.
The killing happened March 2017 on a dark road in western New Mexico while the officer was responding to a domestic violence call.
Cleveland said during a hearing in federal court Thursday that he didn't know the person he was shooting at was a police officer.
