On Saturday, April 29th, motorists driving on Speedway Boulevard inside the park’s Rincon Mountain District came upon a car stopped on the road’s shoulder. The vehicle was smoking and the driver was slumped over the steering wheel. The motorists investigated and found that the woman was not breathing and had no pulse, so pulled her free from the car and started CPR. The vehicle eventually became fully engulfed in flame. When fire and EMS responders arrived, they determined that the woman had sustained an injury of unknown origin to her head. She was pronounced dead at the scene. The county medical examiner subsequently determined that the 50-year-old Tucson woman had shot herself and ruled the death a suicide. A handgun registered to her was found in the burned out vehicle. It appears that the fire was caused by the vehicle overheating.
