Phew. I read everything written on this case at WS, but forgive me if I haven't quite gotten fluent in the case just yet. As for me, I grew up in the Bronx, spent many many summer days at the beach in LI and my parents have lived in the North Fork for many years now, so I am somewhat familiar with Manorville and the Pine Barrens.
I have no actual profile/theory but a couple of things are starting to gel with me. I find it most useful to spend most attention to the GB4 for now, since those are the only victims that I am reasonably certain are related. Not saying none of the others are, just that I am less certain.
One pattern that immediately jumps out at me is that there was a shift in pattern after the first 2, which also corresponds with the time that SG went missing.
The first two, MBB and MB were taken from or last seen in the city. (2007 and 2009) Presumably both were transported to LI by the killer. Both victims had cell phones that were retained by the killer and used for awhile after. I think both victims' cell phones also had evidence that the phone was in the vicinity of Gilgo, or Massapequa (which would be the cell tower used from Gilgo I have read).
Then in spring of 2010, SG goes missing fröm OB.
The next two victims (ALC and MW) are last seen in LI. Neither has a cell phone upon her person.
I think that something did change between the first two, and the last two GB4 cases. One theory is that the killer was a commuter to the city until 2010 and switched to finding victims locally for convenience after he no longer had to travel there for work. There are numerous other ways to explain the differences. But I am leaning heavily towards saying that the brouhaha in OB the night SG went missing may have directly influenced the pattern of the killer, making him change a few details. I don't think personally that SG was killed by the same killer as the GB4, but I am leaning towards thinking the GB4 killer was aware of what took place on OB that night.
And to this day, no one has mentioned a reason that makes any sense at all of why CPH inserted himself into the case by calling SG's family. And presumably to say something along the lines of "she was here, and she is alive but not any longer here" (and a possible unspoken meaning of "there is no sense in coming here to look for her"). But this is just too bizarre to contemplate, so I tend to discount it...
First BBM. Unemployment. I would say that would be your reason for not traveling if you were the commuter. By December 2010 we hit the worse unemployment rate. And the NY area got hit hard for 2009 and 2010.
Second BBM. I am a pair of flip flops on SG connection. No people connected here either just thoughts.
1. Intended to be connected but night went wrong, not SK.
2. Connected. Not with others on purpose, night went wrong.
3. Not connected. Just Guiness Book Worthy Coincindence.
Third BBM.
I mentioned CPH the other day. When the story plays out with all those we know are involved through out that night CPH is never a player. Not until the phone call....I don't discount it. I think there is more to it. There is how many people that live in that neighborhood that have not jumped into the news. He has and from all accounts so far had nothing to do with the night until the call.
The way you laid out the timeline is intersting though.
7/9-2007 MBB NYC (1 body there)
7/19-2009 MB NYC (2 years later a 2nd body. I'm no expert but that's a while no?)
5/1-2010 SG Oak Beach (Cover my porblems here above)
6/6-2010 MW Haupauge (If SG was connected or SK was connected to that night, was a month later because SK was pissed why so quick here)
9/2-2010 AC North Babylon (Again 3 quick months later)
We are a year and a half now from last girl missing...
Now we learn that Blue and Malia were searching the community right around the time MW was place and AC soon went missing???
Then the legs in Davis Park Fire Island bother me....
I guess for me coming to a theory or profile is still very clouded
