There are several things that deeply concern me about this entire investigation. The police report is erroneous for one. That I have on good faith. IMO - The construction worker may be the key to this entirely. I don't have the documents but I'm almost certain somewhere along the lines the police or investigators were denied access to search certain areas. I've been attempting to verify this information. Then there is this, which has been bothering me for quite some time.

John Healy, a former state trooper, said he and several other private investigators have been working to solve the 2004 disappearance of Maura Murray, a case now believed to be a homicide.
After two searches of a wooded area in Haverhill, N.H., where Murray's car went off the road, searchers found two pieces of possible evidence, he said. That evidence, which Healy wouldn't describe, is now in the hands of the state attorney general's office.
Something is rotten somewhere in this case. One witness is now deceased and the initial officer at the scene has since become the Chief and retired. The construction worker? Who knows? There is very little information available.
One would think at the very least based on the Tribune article and statements made that if the investigation is in fact being treated as a homocide, that good detective work would definitely include requesting the searching of the personal property of the construction worker and possibly any subsequent working sites he had access to. He would need to be eliminated as a potential suspect based soley on the grounds he freely admitted he may have seen Maura.
