IMO
BL'S behaviour after GPS death does not resemble that of a man who is contemplating ending his life.
Mowing the lawn, going on a camping trip, using the bank card, getting an attorney.
BL gave the impression that he hated social media and GP's attempts to establish herself as a vlogger, in reality, he likely hated her receiving attention off anyone and hated that her full attention was not always on him. (Professed to hate social media and talked nonsense about how close humans are to primates yet took the time to share lengthy posts on social media himself?) - A narcissist and unlikely to kill himself, deep down he'll believe he can get away with this somehow.
The headstart he was given was planned to a T and thus far is working in his favour but rats always surface.
All my opinion....
I wince every time I read the 'narcissist' diagnosis ad I ask myself what language we used before it became, almost 'fashionable'. That's just me.
I don't think we can guess at his personality type before receiving substantial information.
His social media is just what he chose to project publicly. I didn't spend much time on it because I found it to be pretentious and condescending.
There is no way to know if this was his true nature, maybe a very insecure immature young man who was trying to find his way, a victim to his 'story', whatever that was.
Equally there is no way to know that he is not a cunning brutal killer who tortured and killed a girl that believed herself to be in love with him, and is now openly taunting the FBI with his cleverness and malice- seeking notoriety, delighted to be on the FBI wanted list... notches to belts..
I'm just hoping she had close personal friends who know a whole lot more about the dynamic between them, her fears and her efforts.. I'm hoping that friend or those friends have already been interviewed by LE and are keeping quiet publicly.
We need to know who he is, what he plans next and where he is most likely to be located if he's alive.
We also need to consider that this may never come to a trial because he's possibly dead.
Just IMO
