BOISE, Idaho (AP) — A knee to the groin of a tribal corrections officer could put a Nevada man behind bars in federal prison for up to 8 years. Clayton Amos Lossing of McDermitt, Nev., pleaded guilty on Tuesday in U.S. District Court in Pocatello to assaulting a peace officer.

U.S. Attorney Wendy J. Olson says Lossing was in the Fort Hall Correction Center on May 5 after being arrested for intoxication. While he was being booked into the law enforcement facility of the Shoshone-Bannock tribe, the 53-year-old Lossing kneed an officer in the groin, causing the officer significant pain requiring medical attention.

In addition to prison time, Lossing could also be required to pay a $250,000 fine. He'll be sentenced on Jan. 29. The case was investigated by the Fort Hall Police Department.
