1. Evan Tanner
Former middleweight champion Evan Tanner planned a journey of self-discovery while travelling alone in the desert. Tanner’s plan had been to travel via dirt bike into the desert and camp there until he felt mentally ready to return to training. Unfortunately Tanner’s bike ran out of gas and a spring he went to in order to fill his water bottles was dry.
Tanner texted some friends but turned down offers for help, saying he felt he could get back to his camp. His body was discovered on September 8th 2008, but it is believed that he died on either the 4th or 5th. The official cause of death was listed as heat exposure.
