Ok, I'm not from LI or even US, so I'm looking at it from a macro approach on the info I'm getting on the web blogs, posts on here and the MSM (as I said, only heard of this for the first time a few weeks ago). The below are my own thoughts and in places not agreed 'facts'
I get there is no waterway in Manorville, but if we are working on the theory that the torsos are 'staged', and other limbs not that important to stage/make it harder to identify.
Two torsos were found off the I495 if I'm correct (or the internet is wrong, one of the other). The first body parts found in 1996 in wrapped plastic on Fire Island?
I'm running with the theory there are other torsos not yet found, or not as staged since it might have been early on and the killer not as bold. What if the killer dumped the Torso in Manorville, looped back down Sunrise Hwy (27), looking at a map, there are plenty of creeks,waterfronts to dispose there.
Before he returns home to somewhere in LI.
I'm also running with a theory that there are two separate lone wolves, it's been said time and time again that Gilgo and Manorville are the only two places really in LI where you could do that sort of thing, it's just unfortunate that LI has two active and 'potentially' at large SK. I say potentially as I need to look further into someone for the Manorville killings who is already in the MSM (currently locked up after 2011, probably already named on these forum boards, I haven't looked but it's highly likely),they were ruled out by LE. You hear it all the time, that advances in DNA profiling snare killers later down the line, or killed x but suspected of x more.
You can't ignore this detail either which really nails it for me that we are talking about two or more people - The mutilated bodies were all killed over a longer period of time (talking 15 years potentially, probably closer to 10-12), whereas the GB4 were all within 2-3 years.
Also, I get that some people want to think that it's one killer whose changed their MO, however as I said early on, it's'usually' the other way around, they get bolder and take more risk. Not less risks. Yes you could argue that swapping dismembering and staging for phonecalls displays a degree of the narcissistic pleasure, in my view it just doesn't wash as the Manorville Butcher shows a sadistic side, which the GB4 and Shannan didn't show any signs of (or at least the information released doesn't show it). And yes I get that Bundy decapitated some of his early victims and not later on. However this is one body part, not several.
I am of the belief that the Manorville Butcher did dump body parts in the area AFTER the GB4 were found, not to lure the person titled in the MSM as the LISK out (as theorised by PB), but more than likely,he saw it as an opportunity to clear the cupboards as it were, in a hope that all his known victims would be tied to the LISK as one and the same person(which many of you are thinking). Why would he do that? As detailed by a few experts, dismembering body part killers tend to go years if not several between victims. Sometimes they have distractions to keep them away from killing,moreover they like the heat to die down before striking another victim. Could something like marrying/starting a family slow him down between victims? It's plausible. Could that kid getting older cause the Manorville Butcher to clear the cupboards or fear of an unexpected discovery at his residence? Also plausible, it could really have been a stroke of fortune that this opportunity presented itself.
However, with the cupboard now bare, what now...Was Asian male an opportunistic meeting gone wrong not long after this? It's left field as we don't know what Asian Male went missing.But a rabbit hole nonetheless.
So where does that leave Mr M our infamous pen pal who is more than likely lurking on these boards daily, absorbing all the comments in his basement. For me he 'could' be capable of the Manorville killings based on his condescending style, the location of his dwelling, and the content around the walls of that dwelling (Media cuttings, obsessive personality, dismembered artwork), however something sticks for me why it might not be him, he seems awkward, he's definitely a POI, and that's why the finger of suspicion keeps falling on him.
It's also that awkwardness that rules him out for me on the GB4, those four found in Burlap appear to have been lured to their death by a known john, someone who has been nice and generous to them in the past. Perhaps he's even taken them to dinner after a meet on him before. There is no other reason why I could think why some if not all left their phones behind on a promise of large amounts of money. It's a tactic used by dating couples since the advent of mobile phones, you want the partner's full attention. Perhaps they genuinely thought they were going for an escorting date rather than just meeting a John for a quick time. Exploring the extra time theory for dinner and kindness before, I'm wondering if this wasn't the first time he asked them to leave their phone behind, especially if they had been to his dwelling. "Let's leave our phones here and we'll get some breakfast/dinner at the local cafe scenario".
This kind of social interaction, charisma appears to be beyond Mr M, even on an internet platform where he could literally be anybody he wants. He still think's he's above everyone including the law, the press after their 15 minutes of fame and most certainly you and I. I believe his claim about the NY reporter stalking him, and I believe another SK has pointed the finger at him as he most certainly has talked about Gilgo in his letters. However, you can't just print a story based on one SK's word, against a person not in the media, at least not in the UK, it'd be defamation of character and open to all sorts of lawsuits. Hence why the story was shelved.
But that is why I believe we are talking about 2 SK'ers - Sorry LI, you are bang unlucky, but that's the fallout for having an asphalt jungle, with CCTV and toll booths everywhere. Which leads me to believe that's why Manorville and Gilgo are his hotspots, now more than ever. I believe I read somewhere that Robert Moses Parkway was most probably entry and exit point too, which would make total sense.
There are many red herrings out there, as people have said before, there is a lot of things that just don't make sense. I'm going to expand on one more before I stop this essay. I don't believe it is someone in LE, at least not the killer. However, as people have rightly pointed out. Burke is a shady character, but I read somewhere up to that point 98% of Suffolk County homicides were solved. Something that really hit home to me watching TKS is that the LE in the US is under the same pressures as the UK,keep the stats down, but the money is also low to solve any crimes. I simply believe that the LE wanted to sweep this under the carpet, stick their heads in the sand, not realising the sandstorm which was coming their way. We saw multiple police departments in the US under special measures, I'm sure SCPD didn't want that.
One thing that puzzles me is the time it took to discover the GB4 and the other victims on OP, You'd have thought that at least 2 miles in each direction would be searched by a team, yet either this didn't happen or it did and that's why more turned up via the second killer later on
