Police believe the 17-year-old driver was drunk and without adriver's license.
The crash happened around 2 a.m. on Rosehill Road near Hickory Hill and Country Club Drive.
Investigators say Bryanna Hamilton, 17, was driving a 1995 Nissan when she lost control causing the car to overturn.
Denzel Graves, 16, died at the scene, while Cheyenna Cummings, 18, died Sunday at the hospital as a result of her injuries.
Also in the car at the time were Alya Shaw, 19, Chyna Harris, 18, Benyetta Nicholas, 17, and Isaiah Nicholas, 14.
They all suffered non-life-threatening injuries and were transported to Cape Fear Valley Medical Center.
The teens were at a birthday party prior to the wreck.
Twenty-year-old Tierra Washington, who hosted the party, spoke to ABC11 Eyewitness News Monday. She says she didn't know some of the attendees and didn't supply the teens with alcohol.
"I didn't supply the alcohol, and you got into the car with someone drunk, it was your choice," Washington said.
She also said she regrets throwing the party.
"This is a recipe for disaster," Sgt. Eric Dow of the Fayetteville Police Department explained. "Driving drunk, unlicensed driver, dark road [and] speeding."
ABC11 went to Hamilton house Monday but no one came to the door.
Hamilton is charged with driving while impaired and driving with no operator's license. Detectives say she may be facing murder charges.
