Authorities say fugitive former cop Christopher Dorner died of a single gunshot wound to the head as authorities were pumping tear gas into a mountain cabin during a deadly gun battle with sheriff's deputies.
    
San Bernardino County sheriff's Capt. Sheriff John McMahon told reporters Friday that it appears the wound was self-inflicted.  Deputies said they heard one final gunshot from the cabin as it was going up in flames during Tuesday's gunbattle.
    
Before he died, Dorner killed one sheriff's deputy and wounded another during a fierce shootout.  Authorities initially were unsure whether Dorner killed himself, had been struck by a deputy's bullet or had died in a fire that engulfed the cabin during the shootout.
