Fifteen years after 21-year-old Maura Murray disappeared following a car crash in rural New Hampshire, her father he may finally have found her remains.

Fred Murray never stopped looking for his daughter after she vanished on February 9, 2004.

Now, he believes he may have found a clue to her whereabouts, after being granted access to the basement of a home near where Maura crashed for the first time, since the property was bought by new owners.

He said cadaver dogs and a radar scan indicate she may be buried under the basement floor.

The University of Massachusetts-Amherst nursing student was last seen on a road in Haverhill, New Hampshire, that leads to the White Mountain National Forest on February 9, 2004.

Professors at her university say she claimed, falsely, that there had been a death in her family and that she needed to leave.

Her damaged car was later recovered but Maura has never been found.

Fred believes his daughter is dead, the victim of a crime.

Others theorized that Maura fled, possibly to Canada, or was injured, wandered off into the woods and died of exposure.

The case has been the subject of podcasts and a documentary.

Fred had long suspected that his daughter's body may be in a home near to the crash site. The area outside the home had previously been searched for her body but nothing was found.

Fred had never been able to gain access until the end of last year, after the property changed hands.

Murray said two separate visits by cadaver dogs and a radar scan last fall identified something underneath the basement floor.

'It's been 15 years and I haven't let up,' said Murray, now 76, said in a phone interview from Hanson, Massachusetts, this week. 'The point is, two dog hits and a radar hit. ... That's my daughter, I do believe.'

Murray said the information was shared with state police in December.

Jeffery Strelzin, associate attorney general, said the case remains open and active.

'We are aware of the allegations regarding a home's basement in that area and have considered and are considering next steps,' he said. 'That area was searched by law enforcement in the past, including with dogs, and nothing of significance was discovered.'

Strelzin said the area outside the house was searched.

Maura Murray's family and some investigators believe she just wanted to get away for a few days. She had recently resolved a criminal matter involving use of a stolen credit card and caused extensive damage to her father's car during a crash.

A few days before she disappeared, she was working her security job at UMass-Amherst when the phone rang, and she burst into tears. The caller and the subject of the call remain unknown.

When Maura Murray lost control of her car and hit a tree, a couple who lived nearby called police. A school bus driver who also lived nearby asked her if she wanted him to call police. She said no, but he called anyway.

A police report says the windshield was cracked on the driver's side, both air bags deployed and the car was locked. There was a box of wine on the back seat and a strong odor of alcohol.

'I just want the poor kid to have her own grave,' Murray said. 'I just want somebody to help her.'
