As for how she got to LI, I can't say whether a driver or public transit was used. A third option is she was picked up by the killer himself. Valerie worked the streets, I think it's safe to say at this point. I don't doubt she had a pimp and I hope they've identified and spoken that person if they do exist. I go back and forth between the two and one killer theories. Let's say there is one killer. First we have two cases in which we (the public) don't know how they were actually killed, only that they were dismembered post-mortem. For all we know, they could have been strangled. If that's the case, it's the disposal method that has changed. He would be switching from dismembering victims and scattering their remains to creating a personal a personal graveyard of intact victims. Still, there has been talk of I believe Melissa potentially being dismembered (if I remember correctly it was her arm). So my theory for one killer is just that he evolved. I think if we had more detail regarding how exactly VM and JT died and whether or not any of the GB4 were dismembered, it would be easier to sort out the one vs two killer theories. Let's say there's two killers. This is a bit more simple. We have one killer who dismembers, a level of violence and hatred on par with Bittrolff, and one killer who is more of a collector. Collectors are very hyper-focused on controlling their victims, even after death. He's created his own personal cemetery he can drive by whenever he wants to reminisce. He got off on the idea that only he knew where they were at all times. I think he regarded that cemetery as his greatest achievement in life. He was proud of the fact they were right there, with hundreds of people driving by every day, completely clueless as to what lay in the thick brush. Personally I do believe Bittrolff is responsible for the Manorville murders. There are too many coincidences there for me to ignore, chiefly the fact both happened in his own backyard as you said. Bittrolff bought land in Manorville in either 1999 or 2000 (I have to check my files). He's a hunter and would have been intimately known those pine barrens. Furthermore he was a carpenter with multiple workshop/shed-type structures on his sprawling property, where I presume he would store all sorts of cutting instruments associated with carpentry. Cutting instruments that could be used on a body.
