A 23-year-old Byron resident is in guarded condition at Strong Memorial Hospital after being involved in a rollover accident on Freeman Road at 4:05 p.m.
Speed is believed to be a factor in the accident, the Sheriff's Office reports.
Injured was Amber D. Thorman, who had to be extricated from the vehicle. She was airlifted to Strong by Mercy Flight.
Her 1999 Chevy Tahoe was eastbound on Freeman when the SUV went off the north shoulder and struck a tree. The Tahoe then struck the guide wire of a utility pole, causing the vehicle to over turn three times before coming to rest on its roof.
Thorman was wearing a seat belt.
Byron and South Byron fire departments responded to the scene and handled the extrication. Mercy EMS also assisted at the scene.
The accident investigation is being handled by Deputy Joseph Graff, Sgt. Greg Walker and Investigator Kristopher Kautz.
