Investigators searched a New Hampshire home on Wednesday, hoping to uncover clues to the disappearance of a 21-year-old University of Massachusetts-Amherst student 15 years ago.

New Hampshire Associate Attorney General Jeffery Strelzin said state troopers and FBI agents dug a few feet down into the basement of the home in on Route 112 in Haverhill, but came away with “absolutely nothing.”

Maura Murray as last seen February 9, 2004, after her car crashed on Route 112, which is also known as Wild Ammonoosuc Road. 

Police said Murray spoke briefly with a local bus driver, but was gone by the time officers arrived at the scene. They found her vehicle locked. Directions to Burlington, Vermont, were found in the car. 

Authorities say Murray, a nursing student at UMASS-Amherst, left campus after withdrawing $280 from an ATM. A day earlier, she emailed her teachers, saying there had been a death in the family.

Police have made numerous searches of the area around the accident scene, including the Haverhill home. On Wednesday, investigators were given permission to enter the home again.

“A team of over a dozen agents and detectives went into that basement,” Stelzin told reporters at a press briefing. “They cut that area, removed the concrete and then searched several feet down and covered the entire area and beyond where that disturbed ground had been.

“They located absolutely nothing.”

Murray’s father, Fred, said he believes his daughter was headed to Bartlett, New Hampshire, because she had stayed in a condo there with her family years before.

Now, he believes she is dead, the victim of a crime. He says officials could have done more to find his daughter.

“She wants to come home and be buried in her hometown and she can’t be buried up her and I need help, I need help,” Ferd Murray said. “I asked if the FBI was going to come in and do something and help full time but the answer was no.”
