This is a minor detail but I believe can also be important: He used MB's phone to taunt the sister for quite a while. Now either he had the same phone charger as her (unlikely but possible), went to a store and bought a charger for the phone (Eh, possible but somewhat unlikely) or he told MB he would pay for an overnight and she packed a bag, with her charger included (my personal belief).
Which goes along with what I've thought all along - He's divorced/single and has a place/house to host the girls, finds girls that are willing to do overnight dates, or he has already seen each girl a few times and develops a rapport with them. As for obtaining the sis's number and possibly MB's voicemail password, when girls do overnight stays, that's ALOT of time to talk and share thoughts, pasts, feelings etc. From both the john and the escort. I believe at some point MB probably shared her family's lives and stories and he used that info later.
My guess is that there will be alot of girls who had contact with the SK, but for whatever reason did not go with him on an overnight trip, which could also explain why the victims were from all over and picked up all over the area. Not all escorts do overnight dates. He had to find girls willing to do overnight dates, and it took some searching.
As Shadow posted earlier, I also think he lives in Massapequa, and the Vmail check was him intially using MB's phone, possibly he was looking to see if anyone called her to check on her etc.. He realized his mistake, that it can be traced, and made subsequent calls form all over Manhattan. I think that first Vmail call was his major mistake.
I also think he's not interested in LE recognition or the public attention, he cares about the connection to the girls and their families, that's what drives him and gets him excited...that power.
Great post, NJ. Spot on, imo.
Except...I don't believe the SK checked MB's voicemail. I think she did. The reason I think this is because, no matter if she was a regular or not, I doubt she would have given him her vm code. Why would she? Now, if he's super tech savvy, perhaps he was able to retrieve it from her phone...I don't know.
I also don't think our SK lives in Massapequa, but I do think there's a no tell motel there that he frequents.
Being into patterns, I took the time to look up the days of the week certain dates fell on.
ALC, SG and MW were last seen in LI.
ALC: West Babylon, NY Sept. 20, 2010 (Thurs.)
MW: Hauppauge, NY June 6, 2010 (Sun.)
SG: May 1, 2010 (Sat.)
MB and MBB were last seen in NYC.
MBB: NYPA Bus Terminal July 9, 2007 (Monday)
MB: Tremont section of Bronx July 12, 2009 (Sunday)
Reported date of calls to MB's sister (these may not be correct, so grain of salt):
July 16, 2009 (Thurs.)
July 19, 2009 (Sun.)
July 20, 2009 (Mon.)
Aug. 26, 2009 (Weds.) Reported as being the last call.
I have no way to confirm which dates can be connected to which locations in NYC. It's an unknown, but we do know calls were made from Times Square, NYPA and Penn Station.
VM check from Massapequa: July 12, 2009 (Sunday)
I'm not seeing any pattern that stands out to me. Still looking. BUT, the vm check from MB's phone came from Massapequa on the Sunday she went missing. So, either MB accompanied our SK to Massapequa, or the SK killed her in NYC, carried her body and her phone back to LI, and checked her vm from Massapequa. He wasn't checking her voice mail to see if anyone had missed her, though. She hadn't been missing for more than a few hours. The cellphone then travelled back to NYC on 4 other reported dates (Thursday, Sunday, Monday and Weds.).
One thing we need to bear in mind, I think, is that just because someone is reported as last being SEEN on a certain date, doesn't mean that they died on that particular date. They could, in some instance, have been killed on the day following the last day they were seen. Especially true in this case, because these women worked late night into early morning hours. If x were reported last seen on Sunday at 11:00 pm, she might actually have been killed on a Monday. See what I mean?
Anyway...just some random thoughts to bounce around.
