Harrington's parents confirm a $100,000 reward will be offered for information leading to the safe return of their daughter.
This as a local woman talked to us about a fight she saw that was important enough for her to call investigators.
The woman says she was in the John Paul Jones Arena parking lot the same time police say Harrington was still on the arena grounds. She wanted to remain anonymous for her own safety. She called police Monday night after she saw Harrington's picture on our 11 p.m. news.
"I heard them being very loud and it sounded like maybe like she got smacked or something," said the woman.
The fight deeply concerns the grandmother. She says it unfolded behind her car parked outside the arena the night Metallica took the stage.
"It was my grandson's 17th birthday and my son had gotten him tickets to go to the Metallica concert," said the woman.
At about 9:30 PM, on October 17, the same time police say Harrington had still been on the arena grounds, the woman pulled into a parking space to pick up her son and grandson from the show. A loud noise startled her.
"The two people were in like a hand lock she had her hands on his arm and he had his hands on her arm pushing back and forth," said the woman.
She says girl started walking back toward the arena and the young man headed for the road, but ran back to the girl. She says she looked just like Morgan and it appeared the couple knew each other.
"The girl I saw had her hair pulled back and had a large earring on," said the woman.
At one point, she spoke to them.
"I said don't be doing something tonight that you'll be sorry for tomorrow."
But says the two walked off together toward the road.
"It makes me feel awful because I could have done something else," said the woman.
She only had a vague description of the young man she saw. She says police told her they'd be in contact if they needed more information.
