LANDER - The bodies of three people were discovered on the Wind River Indian Reservation, and the FBI is investigating the incident, a spokesman for the Northern Arapaho Tribe said Wednesday.

The three bodies were found in a home in the Beaver Creek housing development near U.S. Highway 789 just south of Riverton Wednesday morning.

"At the present time we know that there were three victims involved," said Jonathan Barela, with the Northern Arapaho Tribe's public relations office. "We're unsure of the exact time of death. We do not know the cause nor any of the events leading up to the deaths of the three individuals. At the present time, we are unsure of their ages, and their identities have not been released."

Officials with the FBI declined to comment on the investigation Wednesday, other than to confirm that the agency was working in conjunction with the Bureau of Indian Affairs to investigate the matter.

Fremont County Coroner Ed McAuslan said more information would be available today.

Barela said the three bodies were transported to Loveland, Colo., where autopsies were scheduled to be performed.

Jerry Evagelatos, patrol sergeant with the Fremont County Sheriff's Department, said county officers helped secure the scene Wednesday, but the sheriff's department is not involved in the investigation.
