FLAGSTAFF, Ariz. (AP) _ The body of a traveling nurse from Texas who was reported missing after leaving a California desert town nearly two weeks ago has been found in a remote area of northern Arizona, authorities said Friday.

The body of Michael Edwards was found near a Forest Service road north of the Grand Canyon on Thursday afternoon. There was no sign of foul play, said Lt. Rex Gilliland of the Coconino County Sheriff's Office.

"We believe we have a natural death," Gilliland said. "He may have died from hypothermia. Obviously we'll know more after the autopsy and we still want to know why he was in northern Arizona."

Edwards, of McKinney, Texas, was found wearing only his underwear. His clothes were found scattered in the area, and his vehicle and camping spot were found about two miles away, Gilliland said.

Victims of hypothermia can become delusional and begin to think they are warm when they are in fact cold, Gilliland said.

Edwards, 44, was working as a traveling registered nurse in Ridgecrest, Calif., and called his family in Texas on April 13 to tell them he was headed to Sacramento to get a nursing certificate.

His family reported him missing to the Kern County Sheriff's Department two days later.
