METALLICA has joined the efforts to help locate Morgan Harrington — who disappeared during the band's concert in Charlottesville one week ago — by adding $50,000 to the $100,000 reward being offered for information leading to her whereabouts. Also joining the search is the FBI, who will be able to investigate tips from around the country in the case of the 20-year-old Virginia Tech student missing since she became separated from her friends at the October 17 show.According to CBSNews.com, Harrington's father, Dan Harrington, told CBS-TV's "Early Show Saturday Edition" co-anchor Erica Hill investigators were to meet with him and his wife, Gil Harrington, on Saturday to bring them up-to-date on the search for their daughter. "We're hopeful that they would have some morsel of news for us," Gil Harrington said to Hill. Dan Harrington told Hill his "co-workers have raised $100,000 for a reward, and actually, just [on Friday], I received a call from METALLICA and they're working on increasing that to $150,000." According to Rockville Magazine, Fox News' Laura Ingle reported yesterday that METALLICA frontman James Hetfield "made a phone call to the father of Morgan Harrington [on Friday to] offer the band's support and they are putting up all the information of Morgan Herrington's disappearance on their web site. [The band] is also offering up $50,000 to go into the reward to help find Morgan Harrington." Police are asking anyone with information to call the Morgan Harrington Tip Hotline at (434) 352-3467.
