SALT LAKE CITY — A member of the Shoshone-Bannock Indian Tribe has admitted to stabbing a man to death during an argument on the Uintah-Ouray Indian Reservation in 2017.

Leland Cornpeach, 20, pleaded guilty to voluntary manslaughter in the death of Eli Ray Poowegup, 38, in U.S. District Court on Monday. Cornpeach admitted in a plea deal that he stabbed Poowegup, a member of the Ute Indian Tribe, to death with a knife “without malice and upon a sudden quarrel” on June 20, 2017.

As a part of the plea agreement, Cornpeach agreed to serve 84 months in federal prison.  

Cornpeach also pleaded guilty to assaulting two sheriff’s deputies at the Davis County Jail where he was held after being arrested in the stabbing death.
