Authorities say the bodies of Griffin and Bianda were discovered near a vehicle crash along Route 58 in the Turbeville community of Halifax County, near the North Carolina border Saturday morning. Both suffered gunshot wounds.

Aly is facing two counts of first-degree murder and two counts of the use of a firearm in the commission of a felony. A motive has not been identified. The investigation is still ongoing. It is unclear when Aly's court appearance will be.
