Maureen's last known location was NYPA bus terminal, and one of the cell phone calls from LISK to Melissa's little sister pinged somewhere close to NYPA.
Sorta yes, and yes.
MBB has a connection to the Port Authority, yes, but the last contact she made with anybody was a phone call to her sister in which she stated that she was at Penn Station.
Regarding MBB and the Port Authority: From MY understanding of it, all that's known is that "MBB made a phone call to her friend from the Port Authority on July 9, 2007." That can be interpreted any number of ways:
1. There is visual evidence of MBB at the Port Authority on July 9, 2007 along with confirmation (see nos. 2 and 3) that she made a phone call in the area.
2. There is evidence of MBB making a phone call from the Port Authority on July 9, 2007 via nearby cell phone tower data.
3. There is evidence of MBB making a phone call from the Port Authority on July 9, 2007 via testimony from the person with whom she spoke. e.g. "Hey, it's Maureen. I'm at the Port Authority."
Anybody have any idea which it is? No. 1 would be the most helpful to the investigation, no. 2 the least.
Regarding the second portion of your comment, Mountain_Kat, yes - LISK definitely made a call that was detected from a cell tower in the area of the Port Authority/Times Square.
If I recall correctly, the connection that MBB has to Penn Station is similar to no. 3 above - there's testimony that MBB called her sister and informed her that she was at Penn Station.
I hope these posts don't come off as confusing and/or annoying - I'm really trying to run through all of this information (and there's a LOT of it) with a fine-toothed comb. I should note, however, that some people might view this whole thing as negligible - the Port Authority Bus Terminal is a whopping seven blocks from Penn Station.
If I can speculate - and if I'm not mistaken, that's what we're here to do - I think MBB made two phone calls on July 9, 2010 while she walked from her hotel to Penn Station. She got in touch with her friend while walking south on 8th Avenue around W 40th/41st Street and informed her that she was "at the Port Authority" before getting to her eventual destination seven blocks later - Penn Station. At that point, she phoned her sister.
