(CBS/AP) WASHINGTON - Metallica has made a public service video as part of a law enforcement effort to try to catch a man wanted in the death of Morgan Harrington, a Virginia Tech student who disappeared after one of the heavy metal band's concerts.
Composite sketches of the suspect will be featured at bus shelters up and down the East Coast, and a video on the Internet from lead singer James Hetfield urges people to come forward with tips.
"Remember, any information no matter how small you might think it is - could be that crucial piece investigators need to help solve the case," Hetfield says.
Harrington disappeared after an October 2009 concert in Charlottesville, Va. Her skeletal remains were discovered about three months later in a field about 10 miles from the concert venue.
The FBI and Virginia State Police announced the publicity campaign Wednesday. Metallica is also offering a $50,000 reward for information leading to an arrest.
The FBI said the suspect has been linked through DNA to a 2005 sexual assault in Fairfax City, where a woman walking home from a grocery story reported being grabbed from behind, dragged behind a maintenance shed and attacked.
