The crash remains under investigation. The Treadwell Fire Department assisted in establishing a landing zone for the LifeNet helicopter. Upon initial assessment, officials say the victim did not suffer any life threatening injuries. There was a dog riding in the vehicle and was apparently uninjured. After the Sheriff’s Deputies conducted an investigation, the victim lost control of their vehicle, struck a culvert, became airborne and rolled over before striking a tree with the roof of the vehicle. The investigation indicates that excessive speed was a contributing factor. The Franklin Fire Department and EMS personnel were the first to arrive at the scene on Dunk Hill Road. The Delaware County Sheriff’s Office says the driver was found entrapped and partially ejected from the vehicle. A LifeNet helicopter airlifted the victim to the UHS Wilson Memorial Hospital.
