A 16 year old East Texas girl is in critical condition after a one car roll-over in Gregg County. Longview police say 16 year old Amanda Barnes lost control of her Jeep Cherokee around 12:50 this afternoon in the 3400 block of Greystone on the city's north side. Investigators say she overcorrected and her Jeep rolled numerous times over a nearly 300 foot span, partially ejecting her. She was rushed to Good Shepherd Medical Center where she remains in critical condition. Police are investigating whether excessive speed was a factor in the accident.
