RANDLETT, Uintah County — An early morning house fire Sunday has claimed the life of one person.

The Avalon and Roosevelt fire departments were called out at 4:16 a.m. to the fire at a small home on the Uintah-Ouray Reservation. The home was fully engulfed when firefighters arrived.

"Fire crews attempted to enter the structure, but due to the intensity of the fire were unable to do so at that time," said Uintah Fire District Director Jeremy Raymond in a press release.

Fire officials, U.S. Bureau of Indian Affairs police and the FBI are not releasing any information about the victim, pending notification of the man's family. The FBI investigates all deaths that occur on American Indian reservations, except those resulting from natural causes.

Deputy State Fire Marshal Kim Passey arrived in Randlett, located about 15 miles east of Roosevelt, shortly before 10 a.m. Passey expected to spend several hours combing through the rubble of the fire-ravaged home to determine the cause.
