SAN DIEGO — A body has been found near a California desert campsite where former Ultimate Fighting champion Evan Tanner stayed days before.

The body was found Monday in a rugged area of Imperial County near the California-Arizona border. Sheriff's Lt. George Moreno says authorities have not confirmed the identity of the corpse.

Crews have been searching for the 37-year-old Tanner since his relatives reported him missing Friday.

Moreno says temperatures in the area were very high during the weekend, topping out at 114 on Sunday.

Tanner, a former UFC middleweight champion, is from Oceanside.
