A Burning Man participant (L) evades a chasing firefighter and falls into the flames of the “Man Burn” after evading the attempted tackles of multiple rangers and law enforcement personnel at the annual Burning Man arts and music festival in the Black Rock Desert of Nevada, U.S. September 2, 2017. Authorities are investigating the death of Aaron Joel Mitchell, 41, who broke through a two-layer security perimeter during the Man Burn event in which a giant wooden effigy is set ablaze. Nevada's Pershing County Sheriff Jerry Allen estimated that there was a crowd of about 50,000 people who were present when the festival's crew of firefighters pulled Mitchell from the blaze. He was airlifted to the UC Davis Burn Center in California, where he died Sunday morning. The sheriff said doctors confirmed that Mitchell wasn't under the influence of alcohol, but a toxicology report is pending. “We don't know if it was intentional on his part or if it was just kind of induced by drugs. We're not sure of that yet”, Allen said. (Photo by Jim Bourg/Reuters)
