The variation among the bodies found on the beach show a consistent pattern of change. The sloppiest involve the oldest: dismemberment and body parts washing up on a beach in '96, now associated with the rest bundled in a bag 150 ft off of Ocean Parkway. It shows the killer was learning and changing his MO ever so slightly as time went on and as he took note. Why weigh down a body and dump it at sea when it could easily wash ashore? Weigh down a body? Done! Check. Boring and too unpredictable.
No, he learned his developing predilections, and we learned he was too much of a control freak for that--he needed to know where the skeletons are located. He probably got a good laugh at how close to the motorists they were, for a while--his secret, so close and yet so far away, and a constant happy reminder every time he drove down the Parkway. Not just one happy death, but two, then six, eight, ten . . .
What tripped him up was SG, who, btw, had been listed on Craigslist before Backpage. Her age and race very similar to the others. Slight build. Nice eyes. He probably got greedy; wanted somebody in his own backyard. Even he was subsequently shocked by his own carelessness. Probably after May 1, his mantra was, "No more phones! Gotta remember, no more phones!"
Why would somebody dump a body in the marsh? Why not? He did not think the body or belongings would ever be found.
So the murders with the highest degree of violence, were the first ones? In most cases violence escalates, not de-escalates. But hey, maybe this is so very special?
And then, he developed not only a different MO, which, as I admit, but also an entirely different signature? Which is basically impossible because signature includes the ritualistic aspect, that, what he needs from this murders. To change the signature that extreme would mean, his reason to kill changed.
And then, according to your profile, he killed SG and "wanted a body in his backyard" ... in a place, he probably can't even revisit whenever he wants, because of all those brambles and because it's occasionally flooded. And especially the one body, which is allegedly so important to him that he wants her in his "backyard" is the one, he didn't wrap. And aside of all this, if he wanted to keep a body, he could have buried her under a tool shed in his real backyard, on under his basement. That's what other SKs do if they want to keep one. But hey, maybe he is so special?
And then, he returns to his old trophy garden and puts Amber Costello there?
Oh, and of course, this experienced SK let his victim sit at least 18 minutes behind the sofa talk to the police on the cell phone. Later, he drops her, together with convenient ID next to her, another first, in the marsh, knowing, police had her name and his name from that 911 call like a panicking moron?
Sorry, but this idea sounds more like the desperate try to make the evidence fitting to a suspect than finding a suspect fitting to the evidence. It's just listing bodies, ignoring the behavior behind those murders, put them all in one account and if a puzzle piece doesn't fit, using a hammer to make it fit. For me, that's a no buy.
