Goldfinch, you are most certainly correct about him being a narcissist, and like you said, I'm sure LE knows all about him and would nail him if they could prove he had involvement.
There is a chance that he is just a troll, but I can't help thinking, what are the chances that this guy would have been involved in JBs life (as a friend and confidant, according to him), have ties to the area in which they were abducted/ murdered, and have an ideology that would allow for murder (or the justification of murder) if someone dated outside her race.
With that said, I totally acknowledge that he might just be a creep who gets off on trolling people in connection to a terrible tragedy, and the only thing that is really important is who was involved in the murder that night.
I tend to think in terms of probability. And in this case, if you beleive all the things he has posted over the years, it seems very probable he is involved.
To me, if the girls were in Ozark at the invitation of V or his girlfriend, that expenentially increases the odds, he, she, or both were involved in the murders- maybe directly, maybe not.
Another fact that points to his possible involvement is his connection to Johnny B- the only know suspect according to LE.
Johnny B said enough in those interviews that LE wouldn't let him leave, and I've heard there was a jailhouse confession as well. I know he told several stories, but one was a neighbor of his killed the girls. I've heard this guy was a former neighbor of Johnny's. Also, one of the things Johnny said was the killer told him let's go mess with these girls and then got in their car. I think Johnny claimed to have followed them in another vehicle. Also, he said the guy got them out of the car, JB was "in the guy's face" and he shot her. I wonder if it was V and he and JB argued and he shot her and then Tracie.
Again Johnny told many stories, and to my knowledge never accused V directly, but again..the probability of his involvement increases with each connection.
I totally acknowledge that all the reasons I suspect the guy are circumstantial and based on talk - which is cheap- and all that matters are the cold hard facts. But the murder is still unsolved and there is a creep out there trying to make people think he might be involved- without really admitting anything.
I know LE is still working on this, and I just hope they get the SOB soon- whomever he is.
