CHARLOTTESVILLE - More than 1600 volunteers spent their weekend in Charlottesville search for missing Virginia Tech student Morgan Harrington.

"You never know...the next step you take you might find something," said volunteer Edye Adams.

After four area searches in two days Edye Adams is ever hopeful. Adams is a coworker of Morgan Harrington's father. The search is far from her home...but hitting very close to it.

"You just keep looking, you keep that hope, and you keep going, if it were our family I'd want to keep going too," said Adams.

Maps of search areas around Charlottesville lead teams to search for clues. But search leaders say they uncovered nothing connected to Morgan. But they say they don't lose hope until they have a reason to...

"It's very important to this community to be able to support this family in this horrible time," said Bob Smither, cofounder of the Laura Recovery Center.

Bob Smither knows as well as anyone. His daughter Laura was abducted and murdered in 1997. She was 12. Her body was recovered during a search like this one.

"There was resolution in Laura's case.There's never closure but there was resolution," said Smither.

So the search will continue. And volunteers say they'll do their part to remind the public that Morgan is missing...and that she needs someone to keep trying to find her.

"She's gotta be out there somewhere and I'm willing to stay until we find something...until we find anything," said Dustin Smith.

Twenty-year-old Morgan Dana Harrington was last seen Oct. 17 after she became separated from her friends at a Metallica concert.

Virginia State Police have followed up on 350 tips so far. A reward for Harrington's return is at $150,000.
