Today, it's expected that more than 500 volunteers will continue the search for a missing Virginia Tech student.
The three-day search for 20-year-old Morgan Dana Harrington began Friday with about 360 volunteers. Although Virginia State Police say they've followed up on 350 tips so far, no new leads have been discovered this weekend.
Harrington was last seen Oct. 17 after she became separated from her friends at a local rock concert.
The search was organized by Texas-based Laura Recovery Center, named for a girl who was abducted and slain when she was 12. The group hopes to have a 3-square-mile area searched by Sunday evening.
A reward for Harrington's return is at $150,000.
