My theory (ever changing), MM discussed her sisters addictions & relapses & was upset bc of. Add to this her own troubles with the law & accident in Freds car, pressures of nursing school, issues w/Bill and she broke. She left campus, thinking of either hurting herself (returned item to friend after she told her no rush) or just getting away to her place of peace..(white mountains). She didnt intend or think of her car issues, but she had car trouble and exited onto 112, prior to this, stopping for what would be her final fill up at a gas station( her tank was almost full when car wrecked) and it was then that she put the rag in the tailpipe bc Fred taught her this. Once on 112, she sputters out due to the rag solution simply not working....loses control of car into the snow bank. Bus driver comes along asks if she needs help, due to her drinking she lies and says no do not call bc AAA is in route. Bus driver, (former police officer), insists he is going to go inside and call police & fire dept for help and according to reports made by him, she simply said just go...this to me, sounds like she was upset that now she would have to flee...she gathers her most imp items & takes off running...I believe she was stopped by someone with bad intentions at this point...a neighbor, my guess is Forcier needs to be looked into further...his house was just up that road & somebody knows something.
