Just for discussion...
There probably has been thousands upon thousands of times where a gal's car breaks down in the middle of nowhere and nothing happens...
Reminds me of all the people who play the lottery and lose and we never hear about them. But along comes a winner - and that's who we hear about - unfortunately MM might be that one in million "winner" of the having a crime of opportunity take place in the middle of nowhere.
Okay, the same reasoning over odds could be also be applied to her finding a way to make to her final destination and ending it all if that was her desire... or simply being the one out of so many who dies from exposure and is not found..
It a toss up IMO - foulplay, suicide, exposure...
I understand exactly what you are saying.
But there is no shred of evidence that is compelling enough (for me anyway) to be able to totally discount all the things that were happening in Maura's life in just the final four days before she went missing.
If you want to believe a boogey man got her, then you are saying nothing else strange that was going on in Maura's life mattered, because she was met with foul play that fateful Monday night (just like any other young female would've) had they been in the location Maura was and in the situation she was.
It doesn't ring true.
No evidence (not a lick of it) points to anything sinister happening to Maura (beyond her control). Family spokespeople are the only ones to INTRODUCE this theory as a defense to explain away all the other REAL things that were going on with Maura.
If someone is at the top of a building and they are hell bent on jumping off and ending their life and they are right on the edge of jumping, chances are much greater that they will die from the fall, much more than that they will jump and a passing airplane just happens to be flying by and collides with them in mid-air and accidently kills them.
It comes across to me that people are inventing a made-up "passing air plane" scenario just because they feel better about that kind of result as opposed to thinking that someone like Maura that seemed (outwardly) like they had a great life and a great future, would want her life to come to an early conclusion.
Back to the crime of opportunity.
If anyone wants to believe that, that is their right, but wouldn't it be better called a crime of destiny.
Crimes of opportunity happen because someone is able to assess a situation BEFOREHAND and determine that they can commit a crime and get away with it right on the spot.
Maura was in dark clothing in pitch dark after 7 p.m., in the middle of the winter on a lonely highway.
A criminal is not out prowling for their next mark in those types of locations, they just aren't.
And if a criminal chooses to stop for Maura in that particular situation, they are doing so completely blind to the circumstances as to what is going on. they don't know right away if Maura is even a female or a male, they don't know if Maura has a boyfriend with her (its dark out).
I can't see a criminal of opportunity, just taking blind risks to help a stranded motorist and hoping that it turns out to be a young female that is by themselves.
Now if this happened in the middle of the day and Maura was stranded by her car, I could envision someone driving passed the scene (assessing the situation) then coming up with a plan as they back-track to the car and scoop up Maura.
At night time, you see a stranded motorist, you don't even know for sure that they aren't trying to run some sort of scam on you and hurt you (as a driver looking to be a good samaratin)
