So we have to construct that not one, but the majority of the cell phone shops, this hypothetical homicidal John used, erased the tapes (well video files) or had no cams at all. Not just one. Which is quite some stretch to make the homicidal John work before we even talked about the even bigger holes in the logic coming after the cell phone part. For example, MB was last seen in the Bronx, waiting, that someone came to fetch her. The hypothetical homicidal John or a driver? The number of drivers in this business is maybe big but not infinite. And if you follow a homicidal John theory, you have to make a decision, where his kill zone would be. City, Northern LI or at the Islands? Because whatever you try, you end up always with the same problem, a guy, who makes himself standing out by sometimes importing girls over a long driving distance. Remember how MP reacted when he heard, he is supposed to drive out to OB.
ALC and DS, the never-ending story. Closer reading also reveals, that DS stated, it was a regular, he only raised the prices when she had no mood to go out to him. So he didn't ask for "the prices", he asked, at what price, she would be willing that evening. The rub is, if this guy was a regular, and she maybe had a date with him in the weeks before, a stalker could have known about him too.
The phone calls to MB's sister don't indicate, she was actually that long alive. The indicate only, she was long enough alive to get this information out of her. Minus the information, a stalker would have known anyway.
Well, that "degrading the victim as a *advertiser censored*" followed by "justifying his crimes", that is so from the text book. Things are not that easy. For example:
The killer also called the pimp. Now, there is no way in hell, you can emotionally torture a pimp. They come with some degree of sociopathic or even psychopathic behavior on their own. And so, the calls are a direct contradiction to what the exactly same text book says (I reference here to the FBI Whitebook). And if you go over the bits and pieces, we hear about those phone calls, what is the main focus, he is talking about? Right, he talks about sex, and what he did sexually to MB. But what is the other part, the significant part? He talked about MB's lifestyle, where her lifestyle had brought her and where it would bring the sister, if she wouldn't change her ways. That is more along the religious mission driven line than along the usual rubber stamp profile of the white loner sadist sitting in mommy's basement. So, the rubber stamp profile combined with a guy, who doesn't like prostitutes and therefore kills them ... that' a bit like Robert "my favorite baker" Hanson saying, he didn't like prostitutes. Actually, he liked them, which was the reason he killed them. Well, I could go on, but I did it already in older posts over the last two years.
How could a stalker have known? Well, first thing is, there were ads in the internet. Second thing, it wasn't the first time. A stalker who had followed her once would know, she took the bus home and therefore concluded, under stress (she was mugged earlier), she would do the same thing. And he would be anyway at the bus terminal, it wouldn't be a detour for him. Because, well, he's a stalker. If he followed her form the hotel on 46th Street, where would he end up? At the bus terminal. So that is all no witchcraft. And he doesn't have to make contact with them to know they are prostitutes if he picks the first glance at Craigslist or out on the field. If you look at a Craigslist ad from a pro, you can assume, it's a pro. Because of what she offers. Safety measures on Craigslist were two years back extreme lousy (they improved in the meantime to lousy). Any script kid could bring in a backdoor. No art in that. Especially not for someone, who has proven in other aspects already, that he is pretty up to date with more complex techniques like cell phone spoofing. Vice versa, if he just saw her and decisded, that's a nice victim, I go and stalk her, what would he do? Well, we can in the meantime go and search for "similar pictures", for example in Google. We can combine that with other parameters, like city. And we can search the usual suspect sites, like facebook for example, and, in case of someone, we know already to be a hooker, maybe backlist, craigslist and so on. No art in that.
