Disappeared (2010)

Season 3: Episode 16

Virginia Tech student Morgan Harrington promises to meet her father the morning after attending a Metallica concert, but she never shows up. Her panicked parents learn that Morgan left her friends during the concert and never came back. Witnesses paint a strange picture of her behavior outside the concert venue: she was erratic, belligerent, incoherent, and in the company of three young men. Even more bewildering are multiple reports of Harrington hitchhiking late at night on a dark road. Weeks and months go by without solid leads until forensics link Morgan’s disappearance to a violent crime in another city three hours away.
