ATLANTA - Authorities are investigating a police chase that ended with a fatal crash on Interstate 85.
The incident began around noon Sunday. Two southbound lanes of the interstate near Senoia Road were closed for four hours, causing a major backup.
It all started with a carjacking. According to the Georgia State Patrol, two armed teens carjacked a 1996 BMW 325I from a woman in Union City.
Union City police spotted the stolen car and followed it south on I-85 into Fairburn. Troopers said the driver was 17-year-old Cheyenne Pierce, and they identified her passenger as 18-year-old Demetrius Roberts.
At one point, the car reached speeds up to 100 mph, the GSP said.
"When you're driving that speed that young, it is never safe for anyone," Trooper Rick Ceballos told Channel 2’s Liz Artz.
He said the driver lost control, flipping the car several times and both teens were ejected. Then, the car hit a tree.
Roberts survived the crash, but Pierce didn’t. He was taken to Grady Hospital for treatment, but his condition is unclear.
GSP is investigating the crash and the chase.
"From everything I’ve found so far, everything is on the money, by the book," Ceballos said.
