I agree with you Windsor and Dwntwnslim-we should focus on the other victims as well. Any links between them, no matter how trivial they may appear, might be a springboard for an important break. I certainly hope that the Gilgo 4 families are continuing to talk amongst each other, offering support and looking for matches between their lost loved ones. The four categories you have Windsor are good ones.
I'm wondering if the killer ever set foot in any of the motels these girls stayed in, like the Super 8 motel on 46th street in NY that Maureen Brainard-Barnes was at. We know that he didn't come to her room, I wonder if he suggested these hotels/motels to them when he called them? Would he drive around and case the places, looking for where the outdoor cameras were at and a good location to pick them up with his vehicle? It seems as though he's been ultra careful and always picks up the women down the street from where they're staying or their home. Unfortunately, it'd be such a long shot that if he made a mistake and was caught on camera that they'd still have the footage.
I do know that Shannan kept several notebooks/ledgers that her mother was shown with on the 48 Hours special. She said she was checking them all out. I wonder just how detailed these profiles were. I wonder what percentage of their dates occur in the client's homes as opposed to hotels/motels etc.? LE did check out Amber Lynn Costello's roommate Dave Schaller's cellphone which she was using the day she disappeared. Checked the text messages as well as phone numbers and quizzed him on who her regulars and/or weirdo customers were. Her sister Kimberly Overstreet was also looking at her own notebooks, maybe there's a possibility (a very creepy one) that the SK had been with her as well. I would think that at least one other victim kept records, they probably checked out Megan Waterman's cellphone that she left at her motel on Long Island.
Something that positively amazes and confounds me is what did the killer say and do to persuade both Megan and Amber to leave their cellphones behind? He must be very, very smooth and glib, able to put them at ease. I'm now wondering if perhaps he was a regular of both the women, as opposed to being a first time client like I've been thinking so far. I know it's a fairly popular belief that he could've been grooming them, I've felt that it would be much too risky. Well, we do know that he probably gets off on taking chances...maybe he was a regular and met them at those clubs that they went to when they were first getting into sex trade.
And now they've found more skeleton remains in Manorville? Wow...no word yet on whether they are human though? I hate to say it, but it wouldn't surprise me if they found more bodies along the Ocean Parkway...
