GLACIER, Wash. — A 41-year-old Seattle man was found dead in the Nooksack River.

The State Patrol received reports of a naked man near Mount Baker Highway and Cornell Creek Road before noon on Saturday.

Authorities say he was in a serious mental health crisis and that he believed he was affected by demons.

A trooper spotted the man in the river attempting to drive a stake into his mouth.

He did not respond to officers and was taken down the river by the current.

A Customs and Border Protection helicopter and Search and Rescue team assisted in the search.

Kayakers found his body washed ashore later that afternoon.
