BBM - I think that is what he is saying.
Is it possible that might have been what happened? Could the girls have known BG? He happens to be at the trail that day and saw the SC post at the bridge so he knows they are there too - they wouldn’t have had to formally announce their location it was broadcast via the pic. Maybe he’s parked at the abandoned building when he sees the post and drives to where they were dropped off at, walks to the bridge and asks them if they want to go for a ride. They think he’s kind of weird, but he’s got a car and seems harmless. There wouldn’t be sounds of a struggle because they left willingly. Maybe they ride into town (MP - phone pinging around town), but insist on coming back to the trail area because that’s where they are supposed to be picked up. Maybe BG wants to hang out more and he normally hangs out in the crime scene area. They don’t want to go, but he takes them to the cemetery anyway and forces them down that hill. Since he’s acting weird maybe this is when LG decided to record what was happening. Things go sideways very quickly and afterwards he goes back up to his car and leaves.
As a person with knowledge of the area and a LOT of knowledge of the case, is this even possible?
A few things...
1. The timeline is really too tight for this to have happened in that way. LE seems to think that the time between Abby's picture being taken and the girls' deaths as really quickly-less than 2 hours, if I am remembering correctly. Taking them into town, driving around, coming back, etc...not a whole lot of time. Abby's picture was taken a little after 2pm and by 3:30 (before that, really) someone was looking for them.
2. It wouldn't explain the recorded convo about the man behind them. We don't know if they really used the word "creepy" or not, but they did seem to comment on his presence and not in a "let's hang out with him" kind of way. I don't think they'd have had that convo and then gotten into the car with him in what amounts of a few minutes later.
3. It wouldn't explain why Libby started videotaping him on the bridge. Why turn it on and secretly film him and then agree to go ride around with him? (Unless the whole videotaping of him was an accident and she hadn't meant to.)
The scenario would explain a few things-why nobody heard them scream and the phone "pinging around town". It might also explain how they got across the creek without wading through it. I think there are other, more probable explanations for those things though: they didn't scream because they were too afraid, the phone was simply bouncing off towers because the towers were full, and they were either ordered across the creek, crossed back over the bridge (and were accosted THERE), or they panicked and ran.
It's not a bad idea, though. I don't want you to think that I'm pooh-poohing it. When the crime first happened, that's what I thought had happened. I thought the girls had met up with some peers close to their age and that they'd either been bullied or hazed and it had culminated in their deaths. As the facts started coming out, though, my theory no longer made sense.
