Court documents show that the accused Blue Ridge Parkway shooter has confessed to the crime.
Ralph Leon Jackson was arrested Wednesday for last Monday's double shooting on the parkway.
According to an affidavit filed in the Augusta County Circuit Court, he told an Augusta County Sheriff's investigator that he was at the scene and that he shot at both victims.
The documents also say officials were able to test DNA on a piece of cloth 18-year-old Christina Floyd ripped from the shooter's shirt when she confronted him.
Jackson is facing one count of first-degree murder, one count of attempted capital murder, and two counts of using or displaying a firearm in the commission of a felony.
Floyd and 27-year-old Tim Davis were on the parkway to watch the sunset when the shooting occurred. Both were flown to the University of Virginia Medical Center for treatment.
Floyd was treated and released from the hospital.
Davis, who suffered from multiple sclerosis, suffered wounds from a shotgun blast and from a fall over the edge of the overlook on the parkway.
He never regained consciousness and died Friday afternoon.
