Charlottesville, Va. — UPDATED Monday, 10:00pm:
The mother of a murdered Virginia Tech student hopes a new sketch of the suspect will help root out the killer.
The FBI released a new sketch of the man wanted for Morgan Harrington's death, over the weekend.
Morgan was last seen alive at a Metallica concert in Charlottesville in 2009. Her body was found on an Albemarle County farm three months later.
Morgan's mother, Gil, thinks this new sketch could be the turning point in her daughters case.
"If you are one of those who has had some suspicions or concerns, and the hair on your neck has gone up a couple of times, don't filter. Call police and let them be the ones to look into it. That's what we're trying to do, shake loose a killer who is walking amongst us," Harrington said.
The computer-generated sketch is of a person wanted for a sexual assault in northern Virginia in 2005. DNA has linked Morgan's death to that crime.
