Possible, but I can't imagine them driving all the way to Mississippi on bath salts. My good friend who is an ER doctor here in the area said that bath salts are absolutely evil, said that he had seen people come in literally trying to pull their own skin off...
Jaren only had one stab wound that we know of. And then she was dismembered and dumped in the Gulf (or maybe the Pontchartrain). If she were taken to Mississippi, that's an hour's drive--would be difficult on bath salts, I would think. Same with if she were killed in Louisiana--they still had to transport her body to the place where it was dumped.
It doesn't seem like a disorganized, drug-fueled murder to me, mainly because as of yet there was nothing except being videoed leaving Temptations that makes it seem careless or disorganized. It seems more like a gruesome crime of curiousity, thrill.
That's the huge question I want answered. Why dismember her? Not for transportation... removing feet from ankles wouldn't require that. Why was she taken apart like a doll?
