The search for a missing Virginia Tech student continues.

Metallica has pledged $50,000 to aid in the search for 20-year-old Morgan Dana Harrington, who was last seen Oct. 17 outside the John Paul Jones Arena in Charlottesville, Va., following a concert by the venerable metal band.

The reward for her safe return now stands at $150,000, the bulk of which has been put up by Harrington's parents. On Tuesday, the couple will appear on Today to make a plea for help in finding their daughter. They have also set up a website, FindMorgan.com.

The 20-year-old attended the concert with friends, but after getting separated called them to say she was outside the arena, couldn't get back in and would try to find another way home.

Her phone and purse were found the next day in the parking lot of the venue.

Anyone with information is asked to call 434-352-3467.
