COEUR d'ALENE, Idaho -

 A federal inmate completing his sentence at a halfway house in Coeur d'Alene died when he stopped breathing due to a high level of alcohol in his system.

Kootenai County Coroner Deb Wilkey said Thursday that the death of Joseph Newlyn Papse was an accident.

The 27-year-old from Fort Hall was completing a sentence for violating probation on a 2006 conviction for sexual abuse of a minor in Indian country.

The Spokesman-Review reports police are investigating the Nov. 21 death at the Port of Hope transitional housing.

Papse was a member of the Shoshone-Bannock Tribes headquartered near Pocatello. He was buried Monday at Cedars Cemetery on the Fort Hall Indian Reservation.
