The task force investigating the murders of Virginia Tech students Heidi Childs and David Metzler tells us the reward for information leading to an arrest has been increased.
Four years ago today, Montgomery County deputies found Childs and Metzler shot to death at Caldwell Fields.
No suspect in the case has ever been named, but the sheriff's office says it is still actively investigating.
The reward is now up to $80,000.
Virginia Tech added $10,000 to it in the past year.
