Her boyfriend, Dillon Tart --who was driving-- survived the crash.
The two Triton High School teens were air lifted from the crash scene to WakeMed, but Moore didn't make it. Meanwhile, Tart was released from the hospital over the weekend.
After the crash, Moore's friends built a makeshift memorial in front of the store. Her funeral was held at Gospel Tabernacle Church in Dunn on Monday afternoon. Much of the student body at Triton High School attended to pay their respects.
"She was a fine young lady, just one of those great members of the student body that goes about their business being a student and doing what they're supposed to when they're supposed to do it," Triton High School Principal Brooks Matthews said. "It'll be a great loss not only for her family but for the community and school as well."
Authorities say they are still investigating whether the crash was an accident brought on by a medical condition or an intentional crash, set in motion by a domestic fight.
An eyewitness says she heard Moore screaming before the SUV accelerated through the parking lot, hit two parked cars and a curb then flipped.
Fortunately, paramedics were eating at restaurant across the parking lot and saw what happened. They were on the scene within seconds and radioing instructions to a dispatcher.
Dunn Police say they want to examine Tart's medical records to see if there's any kind of condition that may have caused the crash.
They are also reviewing video from Wal-Mart's parking lot cameras and getting help from the Highway Patrol's accident reconstruction team.
Surveillance video from a gas station in the same shopping center as Wal-Mart shows Tart's car speeding off before the crash.
As of Monday, no charges have been filed. Officials say it will likely be later this month before they can decide whether the crash was an accident or a crime.
