Ok Peter if we are wrong in our profile please explain to me an alternative?
Points to consider-
LE including FBI have stated they believe it is an older white male, probable Long Island resident.
All women went missing during or shortly after their last job.
Points to the killer being a client or prior client.
Otherwise how would the killer have known the intimate details of Melissa's life (sister's background, Melissa and her boyfriend's sexual relationship and boyfriend's tattoos, and also details of other victims), which he then used to taunt their families??
1.) LE including FBI have also profiled an older white male in the Flint-Stabber case, in the Grim Sleeper case and the Sowell case in Ohio. Two black, one brown and in fact, one could be really considered "older". But of course, if my job would be to catch a serial killer and I have a good idea who and what he is, I will tell this always to the media to warn him off.
2.) As you point out so correct, all women wnet missing AFTER their last job. We know in one case, Maureen Brainard-Barnes, that is was so AFTER, that she even had time to return to NYC to the bus terminal. And there is not even any proof, she was in LI at all.
3.) Imagine for a moment, you are a SK with an at least average ability in using cell phones. Then you find in your victim's cell phone the number od "sis" ... and the rest is easy to bring out, if you have some time with the victim.
The interesting point in these cases (and in my opinion, we talk at least two cases here) is the victimology. Escorts or prostitutes say nothing in this case. Every second SK goes for prostitutes and in the last years also with increasing tendency for internet/Craigslist escorts. But the basic prerequisite of a high risk life style makes them frequently victims. Only, if you compare to other cases (Hansen, Albright, Ridgway, ...) you will find, the usual prostitute killing sexual sadist/anger assault type usually IS the last John. We can exclude that here, Maureen Brainard would have made it to the bus terminal, if we would deal with that kind of perpetrator.
So, as I suggested earlier, take a look at the victims. What do they have in common aside of the obvious being escorts? Megan Waterman offered bdsm services, which brings her in an entirely different kind of customer circle as the three other GB4. So we know already, we don't deal with one John because one John would have one set of preferences. We also know, we don't deal with a sexual sadist with a taste for change (like for example Albright). Otherwise, we wouldn't have four GB4 with the same ethnicity. That leaves us with either a narcissist if he would see something of himself in them (which is highly unlikely in this case because the visual appearance of the victims is so different) or it leaves us with the category of mission-driven offenders (like for example Billy Glaze). So, no what kind of mission could be a SK whi kills exclusively white prostitutes? Keep in mind, the victims were, as far as I know, found nude. Or at least no remains of clothes were found. Forum rules prevent me from speaking it out plainly, but if you look up Billy Glaze or my website, you can find a possible answer for that question.
What else do we know about the murderer of the GB4? He killed once a year with the exception of 2008. There is no diminishing cool down phase. That tells us, he is probably killing also in other places (which would make him non-local) and only in the summer time in the area at all. But a constant cool down phase of a year and then miss a year is a warning sign. Because it means, you are not dealing with psychopath 101. You can compare the kills/year of other SKs and you will see, how rare this timing is (this doesn't mean, he isn't psychopath in a secondary diagnosis, but it isn't the main reason, he is on the prowl).
There is another thing, the phone calls tell us. He had time with his victim. Probably more than 24 hours to get all the details out. Which indicates, he has a kill site with the necessary privacy. Put that together with burlap wrap and you get someone, who works in a crafting or construction profession, or, that was here mentioned earlier, has to do with farm work in some way.
What else? Oh, yes, the dump site. I stuck on that a while. The dropping of the GB4 is unpersonal and unceremonious. Normally, I would interpret this as fully achieved objectization of the victims. But the phone calls, especially the few hints in which he ranted about the victims life style and the fact, that he also called the pimp/bf makes me wonder. This has more of a justification and a transfer of guilt. Under that light, I am not sure, whether he is really so emotionally distanced from his victims. But then, the unceremoniously dropping of bodies contradicts the care in which he built his collection (almost as if he measured this stripe of the beach out). So putting this together, he is likely a re-visitor or at least was it, before he read in the papers, his collection was transported away. However, if I am right here, he would be very nervous when he drove out to drop a body. This would give LE a chance to look at old traffic camera recordings, wouldn't it?
Okay, that was long enough for now. Food for thoughts.
