David Lee Metzler was 19 and a Virginia Tech sophomore when he and a friend, Heidi Childs, drove to a secluded spot in the Jefferson National Forest on the evening of August 26, 2009. They parked in the Caldwell Fields lot; Metzler had brought his guitar and the outing was described as a quiet date.The pair were attacked sometime between 8:25 p.m. and 10 p.m. The next morning a man walking his dog found Metzler shot and killed inside his 1992 Toyota Camry and Childs dead outside the vehicle. Investigators believe Metzler was shot through the driver’s side window and Childs was shot while attempting to flee.

Several of Childs’ personal items — purse, credit cards, phone and camera — were missing, prompting investigators to consider robbery as a possible motive.A long, multiagency investigation followed. Authorities say more than 1,300 leads were pursued, several persons of interest identified, and DNA evidence from the scene has been confirmed; no arrest has been announced. A reward of up to $100,000 is offered for information that leads to an arrest and conviction.

Does anyone have information about that evening in the Caldwell Fields area or remember seeing either vehicle or the victims that night?
