A man was airlifted from the Burning Man event site Monday night after a truck being driven by a Burning Man employee drove over him while he was sleeping in his tent.

The victim was in stable condition Wednesday morning at the Intensive Care Unit at Renown Medical Center in Reno, according to Pershing County Sheriff Jerry Allen.

The Pershing County Sheriff's Office responded to a report of a vehicle-versus-person accident just before 8 p.m. Monday night at the Burning Man site in the Black Rock Desert, about two hours north of Reno.

The driver, who has been cooperating with law enforcement, told deputies that she drove around a coned barricade and onto a non-roadway portion of the event site. She was driving a 1970 Ford flatbed dual vehicle with a two tier deck attached.

The driver inadvertently ran over a tent that was dark in color and had no lights to indicate it was there, according to the sheriff's office.

The driver told deputies that she immediately stopped the vehicle and attempted to render aid and flagged down a passing motorist to call for medical assistance. Deputies also spoke with witnesses.

The driver did not appear to be under the influence but did submit to testing. The results of those tests are pending. Names of the parties involved are not being released pending the outcome of the investigation.

This is the second serious incident at this year's Burning Man event, an arts festival that attracts 68,000 people annually. On Sunday morning, Aaron Joel Mitchell, a 41-year-old Burning Man participant, died from injuries he received after he ran into the fire of the event's main effigy burn.

The Pershing County Sheriff's Office is investigating both incidents. Burning Man representatives have not responded to calls about the incident, and it is unclear whether the Burning Man employee was driving a vehicle owned by the organization.
