A Wyoming man pleaded guilty Thursday in the shooting two American Indian men that exposed racial tensions in a reservation border town.

Roy Clyde, 32, faces life in prison with no possibility of parole under a plea agreement that spares him the death penalty. Clyde is a former parks worker for the city of Riverton, on the border of the Wind River Indian Reservation.

Clyde admitted in court that he walked into the Center of Hope detox center on July 18 and shot and killed Stallone Trosper, 29, as Trosper lay on a bed. He also shot James "Sonny" Goggles, 50, in the head, critically injuring him. Clyde then calmly surrendered to police outside the center.

Trosper and Goggles are members of the Northern Arapaho Tribe. The shootings have outraged tribal leaders, who have demanded a federal hate crimes investigation.

Victims' relatives were upset after Thursday's hearing because Clyde, under questioning of his lawyer, said he was targeting transients regardless of their race — not specifically hunting American Indians.

Defense lawyer Nick Beduhn questioned Clyde in court about his actions to establish a factual basis for the guilty pleas. Clyde affirmed that he had considered killing transients before the day he shot Trosper and Goggles.
