UNION TOWNSHIP -- A pickup truck that was left unattended while warming up was stolen and then involved in a high-speed crash on Sunday night in Union Township according to the Isabella County Sheriff's office.
Police say a 20-year-old woman jumped into the unattended 1988 GMC Sierra pickup outside of the owner's residence.
The woman made her way to US-127 southbound.
The owner of the pickup advised the police that the woman driving the pickup was going over 100 miles-per-hour.
The sheriff's office says that she lost control of the pickup and left the roadway to the west and went airborne.
The truck then slid through a fence at Genuine Road, then crossed Genuine Road and went into a ditch.
After going into the ditch, police tell us it hit some small trees and started to roll numerous times, eventually ejecting the woman, who was not wearing a seat belt.
The pickup eventually stopped rolling on Maple Creek Golf Course.
The woman driving the pickup was taken to McLaren Mid-Michigan Hospital and then flown by helicopter to Covenant HealthCare in Saginaw.
The extent of her injuries are unknown at this time.
Charges are still pending.
Police are still investigating.
