It's so hard to say because I don't think we have all the (honest) facts about what happened at the end of Shannan's night. I agree the drivers story is a little suspicous.
There are two main points that don't add up for me. The first being that the 'dump site' is located so close to JB's house. Seems a little too coincidental to me that he killed her right after he left a house located next to his dump site. Sure, he could have driven girls there before but it just doesn't really add up to me.
The second is the fact that Shannan fled the house. If JB was totally innocent, wouldn't she have had the time to call the police, give them his exact address and wait 5 or 10 minutes for them to arrive. The fact JB had to call the driver (how did he even have Shannan's driver's number?) and ask the driver to come just doesn't make a lot of sense. I've read in numerous sources that the john picked up Shannan at another location and drove her to his house himself and that the driver waited outside the gate. So, why, if she had so much space from the driver wouldn't she have been able to escape from him.
Hi -
I'm trying to dismiss the driver as a suspect (or not) based on exhausting any plausible situations that would explain how he could be both the SK and responsible for Shannon's fear & disappearance. This is because I feel it is logical to use an assumption that the murders & Shannon's situation are linked as a starting point (and move on from that if disproved.) That would also make him and JB the first to investigate as suspects, and move on from there.
So the only thing I can think of that would possibly explain how the driver could be linked to both would be if the choice of his dumping ground (where at that point he would have left two bodies) was also somehow linked to JB. Otherwise, it would indeed be too much of a coincidence. So what could that link possibly be? The only thing I can think of would be that JB is a john, and that means he could have booked other prostitutes other times, and the driver may have discovered the area that way and just realized it was perfect for his purposes. That isn't necessarily probable, but it isn't impossible at all. However, for the rest of the scenario to fit in, it would also have to mean that the driver intended for SG to be a victim that night after she visited JB, because otherwise again it would just be too coincidental (that she would become afraid of something and make a scene unless it was connected to him.) The only thing that would make sense in that case would be that she happened to get a call to go to JB's, and he took that as an opportunity to plan to do something, which in turn would only be plausible if for some reason he didn't think people would - or if he was really bold - could - connect him with her disappearing (e.g. he knew no-one else knew she had that or any appt.) Again, not all that probable, but not impossible either. But for that to be true, you'd then have to have an explanation for why she suddenly seemed to clue in that she was in danger from him. I don't have a possible explanation for that! Of course, his actually being responsible for her disappearance would at that point have been not a choice - he would have felt it probably wasn't a good idea but he had to do it and take the risk of being linked.
What I'm positing sounds almost mundane (he found the area bringing someone else out there in the past; then when another escort - SG - got a call to go out there he just decided to use that as an opportunity to do something (laziness? the idea of being out there stirred a compulsion? whatever); she somehow discovered something that made her fear him, his plan went awry, but then he felt he had no choice & since he still had the opportunity he did it.) but sometimes things really are just that seemingly dumb!
I don't think it's entirely impossible. And it would fit in with a bunch of other things, as tabled in my previous post.
That being said, I do agree it's not exactly likely either! But that's why I'm throwing it out there...
With regard to your other point: she didn't want to leave the house, apparently. I always thought that was curious, if it was true. (That's why the only thing I could think of if JB was the perpetrator was that it wasn't that she didn't want to leave, but was already hiding from JB in another room or something, and didn't know how to get out - HE said she didn't want to leave.) Anyway, back to the driver theory - it's true - if she was just afraid of the driver, why wouldn't she ask JB for his address (she was already calling 911 so she wasn't afraid to involve them) or his help? Maybe he wouldn't tell her (thought she was just hysterical, didn't want the police coming by.) She just wouldn't leave and was trying to get the police there, but then JB got the driver - the very person she was afraid of - to come and get her, so THAT'S why she ran out in a panic. Because once outside it really does seem like she was hiding and running from the driver, I have to admit. (I've always leaned towards JB before this.)
You brought up something I've been curious about - reports that she went somewhere else first and then went to JB's. You said she was driven there by him, but I haven't heard that part before. Is any of this verified? Or does it come from early inaccurate reports that said she had an appt. on Fire Island, which could just have come from it's proximity. I be very interested in knowing once and for all if any of that is true - did the driver take her right to JB's or not? Does anyone know for certain, and if so, how?
Anyway, she didn't have space from him when she fled the house - he came into the house. And prior to that, even just "down the street" is too close when you're terrified of someone.
