DAWSONVILLE — One of two teenagers who suffered serious injuries in a single-vehicle wreck last week in eastern Dawson County remains hospitalized.

As of Thursday, 18-year-old Kayla Gourlay of Cumming is still at Grady Memorial Hospital in Atlanta, where she was taken after the crash, authorities said.

The wreck occurred Jan. 13 on Couch Road. According to the Georgia State Patrol, Gourlay reportedly lost control of the Ford Focus she was driving in a curve north of Lake Drive.

The vehicle traveled down a steep embankment and overturned at least twice before coming to a stop in a creek.

"While negotiating a right-hand curve, the driver was traveling at a high rate of speed and too fast for the curve, causing her to lose control," said Robin Stone, a spokeswoman for the state patrol.

Gourlay was thrown from the vehicle, Stone said, as was her 17-year-old male front-seat passenger. He was taken by ambulance to Northeast Georgia Medical Center in Gainesville.

The two backseat passengers, both of whom are also teens, were not injured in the crash.

According to Stone, Gourlay faces numerous charges, including driving under the influence and two counts of serious injury by vehicle.

She also has been charged with failure to maintain lane, reckless driving, seatbelt violations and purchasing/possession/manufacturing/distribution of a controlled substance-marijuana.
