I just do not see Maura taking her own life that night. If she did kill herself, and she did do it by climbing a mountain with booze to freeze to death, it would have to be during the daylight hours, IMO. I get that the crash in NH would've put a wrench in her plans but it was so dark outside that night, she would've been nearly blind trying to go up the mountain. It doesn't make any sense that she would start scaling a 4000 ft. mountain in the middle of the night, even if she was suicidal. At -7 degree low temp that night (at regular altitude, let alone on a mountain), she would not have made it very far at all and would've had to get a ride to even make it to one of the mountains to begin with.
So she would've had to get a ride that night, reach one of the 4000' mountains, and it's still dark by the time she reaches her destination - where did she stay that night? She didn't have much cash on her, and her cards were not used. People who kill themselves usually try to make it as painless as possible, I don't know why Maura would want to spend her last few minutes in terror blindly climbing up a mountain in the middle of the night. It's possible, I guess.
There's also the question of what, if any, alcohol did she even take from the car? She bought stuff to make White Russians, was she mixing herself drinks on a mountain somewhere on a suicide mission? Was all the booze in the car and "accounted for"? That part is unclear.
I still think there are too many things that don't make sense in the suicide theory. She would've had to have been absolutely bound and determined to kill herself, with total tunnel vision that nothing, no matter what, was going to stop her.
Maybe Maura wanted to make people think she killed herself? Maybe she never had any intention of going to the mountains and was leaving a false trail?
In any case, I agree that all of the mountains she searched for on the internet should be thoroughly checked for a potential body. There is a chance Maura is on one of them - but IMO, just a chance.
I agree. She wouldn't be able to see the trail. There are no lights. Also, she didn't have the proper shoes to even get started. IIRC, there was snow on the ground. Climbing a snowy trail is a lot of work. Just getting to the trail will wear one out. She left her gloves in the car and if she brought the bottles of alcohol, they would have been clanging on her every move. Supposedly, it was only 32 degrees that night. It was warm for February, so I think she could have got far down the road, if she didn't accept a ride.
On another thought, didn't she bring her running gear with her and it was found in the Saturn? If this is true, then why did she bring it if she was suicidal? JMO
