Her parents, Gil and Daniel Harrington, now say whoever did this to their daughter must be captured and tried in court.
"At least we now have some peace and we're able to have some closure today," Daniel Harrington said Wednesday, reports The Washington Post."We now need to find the person who did this, and we will not stop until that person is brought to justice."
The Harringtons believe their daughter was abducted from the concert by someone familiar with the area, and said that the condition of Morgan's remains show that she probably died shortly after she vanished. "This is not a random place that someone came upon accidentally. This is known to someone here," Daniel Harrington said.
"For the first time in 101 days, I am not thinking every minute, 'What is he doing to my daughter now? What is he doing to her? What is she having to endure?' " he said. "She was a long time in that field. I am happy that she was not alive long, enduring unspeakable things."
Authorities have yet to determine how Harrington died or even if she was murdered, though law officers are treating the case as a homicide.
Among the ways Harrington's parents hope to remember their daughter, they said, is by possibly initiating a national campaign to safeguard college campuses. "We can figure out how we can honor Morgan and remember Morgan, and maybe make it a safer place for all," said her father.
On the Metallica Web site, the band extended the following message: "Our most sincere condolences go out to the family and friends of Morgan Dana Harrington ... Mere words cannot express the anguish and grief that we know her parents Dan and Gil are feeling, and our thoughts are with them."
