FARGO, N.D. (AP) — A man accused of killing another man by running him over with his SUV on the Spirit Lake Indian Reservation in northeastern North Dakota has pleaded guilty.

Lance Robertson is charged in federal court with murder in the death of 18-year-old Larse Azure Jr., of Fort Totten. Robertson faces a maximum penalty of life in prison.

Authorities say the 27-year-old Robertson was drinking with five other people in his Dodge Durango early on Dec. 19. Several occupants allegedly argued with Robertson about his erratic driving and eventually left the vehicle while it was parked on a reservation road. Robertson allegedly ran over Azure as he was waving his arms at Robertson to stop.

Defense attorneys say Robertson was diagnosed with bipolar disorder 10 years ago.
Sentencing is scheduled Sept. 6.
