Thousands to Help Find Missing Metallica Fan Morgan Harrington

The masterminds behind a three-day search for 20-year-old Metallica fan and Virginia Tech student Morgan Harrington, who has been missing for close to three weeks, told reporters Thursday night that they expect more than a 1,000 volunteers could turn out for the search effort's kickoff, which is scheduled to begin Nov. 6 in Charlottesville, Va., and run through the weekend.

But Harrington's parents are asking for more volunteers, hoping that the search will yield some trace of the missing student, who hasn't been seen since vanishing from a Metallica concert on Oct. 17. The search will be conducted from daylight until dark, according to reports.

Harrington's parents aren't alone in their search for Morgan, who was last seen in a Pantera t-shirt, black boots and a black mini-skirt. Joining the hunt are the folks from the Laura Recovery Center, a Texas-based organization that seeks to prevent abductions and runaways, and works to recover missing children by fostering a Triangle of Trust among law enforcement, communities and a missing child's families.

"We just know there will be a lot of people," Janice Liggett, a volunteer coordinator for the Laura Recovery Center, said ahead of Friday's search. With more people involved, the organization believes they'll be able to cover more ground for clues, and will once again go over areas already searched by the police.

The additional assistance from the Laura Recovery Center comes at a time when temperatures are falling and the days are getting shorter. For some volunteers, helping in the three-day search was something they just had to do.

"I just feel compelled to go, there's so much information, but yet there's a lack of information and I just want to be there, I want to be part of it," one volunteer told reporters.

Last week, Metallica's Kirk Hammett spoke about Harrington's case. "We are staying positive that she will be found soon," he said. "We are all hoping for the best and praying for her and her family. We all have children and as parents ourselves, it's our worst nightmare for a child to go out and not come back home. We empathize with that greatly, so we are doing what we can to help find her. We are staying positive."
