FAIRFAX, Va. (WUSA) -- Nearly two and a half years after she was murdered after attending a concert at the University of Virginia, Morgan Harrington's killer has not been caught.

The Virginia Tech student's body was found about 10 miles away in a field, three months after she disappeared the night of the concert.

Saturday, her mother spoke outside a Giant in Fairfax where another girl was attacked in 2005. Police believe the same man is responsible in both crimes.

Morgan Harrington's parents launched a national campaign to help find their daughter's killer.
