A man who shot and killed a tribal police officer in a remote corner of the nation’s largest American Indian reservation has been sentenced to 30 years in federal prison.

Kirby Cleveland, 37, was sentenced Monday in U.S. District Court for murdering Navajo Nation Officer Houston James Largo four years ago in western New Mexico, ABC reports.

In 2019, Cleveland pleaded guilty to second-degree murder, which carried a maximum penalty of life in prison. He also pleaded guilty to violating the conditions of his supervised release in a previous case in which he forced his way into a home on the Navajo Nation armed with a baseball bat and assaulted a woman in 2012.

Largo was shot while responding to a domestic violence call.

Cleveland acknowledged that he consumed alcohol that night and shot and killed Largo March 11, 2017, on a dark road with a rifle.
