(NECN: Scot Yount, Chester, N.H.) - "Today's her parents anniversary," said a tearful Rebecca Tyning.
Thousands of flyers have been posted in Dover, N.H.
That's the last place police have a ping from 19-year-old Elizabeth Marriott's cell phone that put her near the hospital just after 10 p.m. Tuesday night.
"We are going on three days here with a girl that just doesn't not keep connections with her family," said Tony Hanna, Marriott's uncle.
The University of New Hampshire sophomore disappeared after telling friends back in her home town of Westborough, Mass. that she was heading to visit new friends she had made since moving in with her aunt and uncle in Chester.
Police have amassed a large force.
"It is comforting that the FBI is involved, but it is also scary," said Tyning.
As Marriott is a new driver, the family worries she may have driven off a road and need help.
"She has never done this before, this is out of character, she is a very responsible young girl and we are really worried, really worried," said Tyning.
The family is organizing on its own and has hired a private detective and put up a $10,000 reward. They are concerned about the possibility of foul play.
"She is a very pretty girl, she's 19 and when we are 19 we think everybody's their friend, and that's the scary part," said Hanna.
"We just love her and we want her back," said a tearful Tyning.
The family is now offering a $10,000 reward for her safe return.
