If we remove Shannan (and the Manorville victims) from the equation, and concentrate on JUST the GB4, are there any common threads that might link these 4 women? Apart from the fact that they were escorts, that's a given.
1. We can connect Amber and Megan to the Express Holiday Inn in Hauppague.
2. We can connect Melissa and Maureen to dancing.
3. We can connect Melissa, Maureen and Megan (via AC) to NYC.
4. We can connect Melissa, Amber and Megan to Long Island in life, and all 4 women to Long Island in death.
5. We can connect all 4 women (in death) to asphixiation and burlap.
That's all I can come up with. We have nothing to connect these 4 women to Brewer, Pak, CPH, or any other person of interest, as far as I know. And the ONLY connection we have between these 4 women and Shannan Gilbert is the fact that the GB4 were found due to Shannan's disappearance. We also have nothing to connected these 4 women to any of the other bodies found nearby.
Am I mistaken in any of what I've said?
