With all due respect to my fellow Websleuthers, you don't have a friggen idea what you are talking about, and neither do I, for that matter. Flash, the cops don't seem to know much more than we do.
We don't really know if the GB4 and SG are connected to the other 6 bodies. We don't even know who the other 6 bodies are. Do we really know if they are prostitutes.
The only thing we do know is a body in Manorville is connected to body parts in Gilgo.
We really don't know if the GB4 and SG are victims of a serial killer in the same category of a Rifkin, Dahlmer, Gacy, etc. They may well be victims of a sex white slavery ring.
After 33 years of the disappearance of Etan Patz have the police and FBI dug up a building basement and all but accused an individual of burying Patz's body. Now they swithched horses in mid-stream and are concentrating their efforts on a new suspect, a man with serious mental issues that supposedly confessed to killing Patz. For whatever reason the FBI doesn't want to agree with the NYPD. The Manhattan DA seems to be of the same opinion as the FBI.
This case can be as far away as the moon from being solved. It is a possibility an arrest is being made as we speak. You just don't know because the police just don't know.
Son of Sam might still be out there if he stopped killing. He got caught despite the police department. Had it not been for the Task Force captain sending out detectives to re-canvass the area near the Moskowitz murder, Sam may still be out there. That is when the detectives learned a ticket for a fire hydrant violation had been written on the night of the murder. The cops that wrote the ticket never bothered to turn it in despite the fact a murder was committed within yards of where the ticket was issued. And they continued to deny they wrote the ticket. LUCK and Experience, nothing more.
I believe in the methods of behavioral profiling. I know, not everybody does. But if everybody would, Etan PAtz case would have been solved when profilers told LE to look for someone who WORKED in the area but didn't live there, not someone who lived there but didn't work there.
For the same reasons, I say, Manorville and LISK are two different SKs. That doesn't mean, that some of the fresher bodies in Manorville are product of the occasional garden vareity murder case, like drug dealer fights, or as the other guy, who had to get rid of an ODed victim (so no murder at all). So what we really talk in Manorville are the dismembered bodies of whi parts also popped up along the beaches.
Compare:
LISK - builds a neat graveyard from his trophy kills
Manorville: Dismembers the bodies and spread them all over the place
LISK - all his victims are Craigslist escorts
Manorville - the only identified victim was a street corner prostitute
LISK - tried to keep his bodies hidden
Manorville - placed torsos/limbs in places where they had to be found
LISK - local to NYC, familiar with Gilgo and the other beaches
Manorville - local to Manorville, familiar with Gilgo and the other beaches
LISK - medium kill frequency, ramping up after he got attention
Manorville - constant low kill frequency
So from my point of view, we deal definitively with two. Of course, since this is based on behavior, it can be ignored any time, but usually that doesn't make it wrong, it takes only longer to find those guys (like in the Etan Patz case for example).
Now, SG. She wasn't added to the graveyard, LISK had built with so much care. But the victim killed after SG's disappearance was added to this graveyard. Which, since SG's disappearance didn't cause too much media attention, indicates, LISK didn't know about her and her disappearance. So, not connected.
