The rifle seller had left the gun in the back of a pick-up truck on his property so 21-year-old Christopher Webb could look at the gun. The seller wasn't home at the time.
Selena was taking a picture of Webb holding the gun when Webb unintentionally discharged the weapon. Selena was shot in the chest.
Selena was taken to a local hospital and died before she could be airlifted to a medical center in Charlotte.
Webb told police he didn't realize there was a magazine in the rifle. The district attorney is reviewing the case.
