Thank you courtfollower. I will base my questions off of this timeline:
Articles released early on in the case state that LE believe something happened to B within 7 minutes of leaving the hotel. Per this timeline, B left Blue Water at 8:48. 7 minutes later would be 8:55. That said, the timeline also indicated that JG received his last text from B at 8:58. IMO, either LE's assumption is wrong or the timeline is wrong. 7 minutes is a very specific time and LE must have a reason for thinking that.
From what I gathered from the PC, the FBI believes she was held for several days before being killed. One thing that is striking me, I am bouncing around from page to page and not being thorough, but BD's boyfriend immediately became suspicious of her being missing. I wonder if she texted him something else that made him worry. Having been to MB many times, cell service isn't always the best.
OK, fine, giving this timeline a couple minute leeway - what about the text from B's phone at 9:15 where she texted a friend (unknown who) that she was going to visit a friend at another hotel (unknown where). By all accounts, B had already met with foul play at least 15 minutes prior to this text being sent.
OK - let's give the timeline even more benefit of the doubt. Let's assume B sent that text at 9:15. That's still not enough time for the perp to drive to Surfside Beach (reportedly a 15 minute drive) after abducting B.
Additionally, why did it take this perp 2.5 hours to drive 1 hours worth of distance (MB to Georgetown/Pole Yard Landing)? I doubt they were going this drastically slow because that would draw attention to their vehicle. IMO, they were taking B to her holding place and then, where the final ping occurred, is the disposal site of the phone. For this reason, I'd like to know where B's phone was pinging between 9:30-11:58. I think that would tell us where she was held.
