GREENFIELD — A woman was thrown from her car and another person was injured after their vehicle flipped into a cornfield Friday afternoon, police said.

The single-car accident occurred around 1 p.m. in the 4300 block of North State Road 9 in Greenfield.

Investigators say Sara Chastain, 30, of Indianapolis, was driving southbound along State Road 9, just south of Maxwell, when her vehicle drifted into oncoming traffic.

Chastain over-corrected, police said, likely jerking the car’s steering wheel and causing her to lose control of the vehicle.

The vehicle careened off the west side of State Road 9 and flipped several times, coming to rest in the middle of a cornfield.

Chastain was thrown from the car and suffered traumatic injuries, police said. Investigators do not believe she was wearing a seatbelt at the time of the accident.

Justin Wilder, 38, of Maxwell, who was a front seat passenger in the vehicle, was also badly injured, police said.

Ambulances from the Greenfield Fire Territory transported Chastain and Wilder to Indiana University Methodist Hospital in Indianapolis.

Traffic in both lanes of State Road 9 was slowed as emergency crews worked to clear the scene of the crash. A tow truck was called to the crash site to help pull Chastain’s vehicle out of the cornfield.

Though their injuries were considered serious, Chastain and Wilder are expected to recover, police said.
