However, considering the details of the days leading up to Maura's vanishing act, I believe there is a strong probability that suggests Fred may be the one other person who knows why Maura went to New Hampshire in the first place.
Consider: The accident reports.
Maura picks up the reports related to the Saturday night accident. She is supposed to give them to her father, Fred. They are found in the car she was driving when she disappeared.
Consider: The location.
Many early reports of Maura's disappearance treated Haverhill as this weird out-of-the-way place Maura would never go to. But she had been on that very road dozens of times. She camped with her father at Jigger-Johnson, down the road, every summer. When she traveled to that area, it was always with Fred.
Consider: The alcohol.
Maura bought more booze than any one person could drink.
Consider: The Londonderry ping.
I believe this search warrant. And if its real, than someone near Rt. 93 called Maura earlier in the afternoon the day of her disappearance. That is the route one would take if you're driving up to the Lincoln/Jigger-Johnson area from the eastern region of Massachusetts. I believe whoever placed this call was the person she was meeting up there.
Consider: The rag in the tailpipe. I spoke to Mike Lavoie again. He says the rag was stuffed way up in there. The only reason you would stick a rag into a tail pipe like that would be some strange attempt to keep it from running. The only person who has given an explanation for the rag is Fred Murray, when he stopped by Lavoie's home, where his car was being impounded in the days after the crash. He said he'd told her that placing a rag in there would keep it from smoking. What. Utter. Bull. Shit. If I'm looking for a missing family member and I hear that someone has placed a rag in her tailpipe some time before she crashed and disappeared, I'm going to be all over that. Even if I suggested something so stupid as that it might keep smoke down, I wouldn't admit it. It's a clue. And a clue that would keep police interested in finding her. The ONLY reason I can see mentioning it is if you know your fingerprints are gonna be all over it. We don't know where that rag came from or who put it there. But Fred wants you to know that he's touched it at some point in the past.
Consider: Fred was unreachable after Maura's disappearance. Police tried to call him at home and only got a message. He didn't call them back until much later.
Consider: Fred's vehement aversion to anything that happened to Maura in the days leading up to her disappearance or why she was up there. "It's not important," he said over and over and over again. Again, as a parent who supposedly doesn't know why Maura went up there, I'm going to assume everything could be a clue.
Consider: Fred's reluctance to sit down with detectives. He refused to be formally interviewed, on record, by police for 2 YEARS. 2 Years, his daughter was missing and he wouldn't meet with police. And when he does, he brings lawyers. What was said in that interview will remain secret until this case is solved. But more than one source has told me off the record that some of the questions pertained to the nature of his relationship with Maura and why on earth she came to his motel room at 2:30 in the morning and stayed through the night.
Fred's a master manipulator. Good at spin.
But if you look at the probability, you come to the conclusion that the most likely scenario, in fact the only one that explains the evidence, strongly suggests Maura was driving up to New Hampshire to meet her father and, perhaps, even did meet with him somewhere before she vanished or ran away or was killed.
