I have a little escorting knowledge under my belt from an experience fifteen eyars ago in Boston. Not my cup of tea, very brief, very hideous, later alligator... but I have seen several posters question JB's stating that he had Shannan to a "party."
In the escorting world, a john will ask for a girl who likes to "party" if he is into cocaine. On the phone with them, if they say, "Do you like to party?", it is code for "Do you do blow? Will you do blow with me?" A girl who is escorting and into this type of thing will jump at the chance to "party" with a john. A girl who isn't into "partying" is not someone who interests these kind of men. They like to do lines for hours with a girl who enjoys it, a girl who is not shocked by it. It's a sense of excitement and comraderie the johns are after, I suppose.
I hesitate to implicate this person in this kind of activity, I might be going out on a ridiculous limb- who am I to say?- but this has struck me repeatedly every time I see mention of this supposed "party" he had SG to at his home. Cocaine. Party. Etc.
There are no details of a real party, no guests stepping forward, etcetera.
Shannan was disoriented and very excitable, upset, possibly paranoid... she had been at JB's home for hours and hours, perhaps three, as some reports say, when she ran off and ended up at the elderly neighbor's home in a panic.
Escorts who are willing to "party" often stay far longer than the usual hour time slot. Men who call willing girls for a "party" are able to, ahem, transact business for quite a longer time period than a sober, unaltered man who is not "partying." (Cocaine makes the male genitals impervious, in a way. Sorry for the TMI, just trying to put some thoughts out there.) This "party/cocaine" theory might explain why he and she were together so long, and why she was so messed up, according to witness reports.
Another thought I have: Many men who call escorts, whether independents or girls working for a service, do so on a regular schedule. Like, every Friday. Every other Saturday. It's common for the men to make it a routine act. JB was a successful business owner and he had money to burn, on girls, on "party" material, what have you. I do not believe that SG's disappearance and these bodies in the area are not connected, whoever it is that killed them. It's Ocam's razor for me. Too much of a coincidence to be unrelated. My mind simply will not allow it.
With my background, considering all the creeps I met in a very short, very disturbing time when I did what I did in Boston as a lost, recent college grad back in the mid-nineties, this bothers the he!! out of me. These poor girls never had the chance to put this degradation behind them and become happy, loving, successful women, mothers, teachers, artists... calm people, centered people. I had that chance and I will be forever grateful. May they rest in peace.
