After reading up on this for a few days, and coming across this thread, I had a few thoughts I'd like to share. I hope you guys will welcome me and I'm excited to hopefully contribute.
Some quoted posts in the thread seem to have been deleted so I may be missing some things that you guys have already seen or answered. I also didn't catch Nancy Grace and am only catching up, so forgive me if I'm confused or asking repeat questions. In the beginning there's lots of talk about the locations of the cell phones. I didn't see anyone point this out, but at first, before she says they're on the bodies, Johnny's mother says they're "on the ground." Did I hear this wrong? A minor point, I'm sure, but there was much discussion about it. Was there ever confirmation on this exactly? I've read so many different things... If the phones WERE literally on their bodies, perhaps it's because the perp thought that one or both of them could get free to call 911. Unlikely, but it is something to think about. Def puts a different spin on things.
Another minor point, maybe, but I'm curious. Why did Johnny need to pick Tiffany up if she had her own means of driving by later? Am I assuming that her friend drove her?
What kind of key was it that was found under Lisa? I only read it had a number on it, but that doesn't mean much. Looking at my own key ring, they all have things on them, but from the size and shape I can deduce what is probably for what. Was it smaller? Did it look like a regular door key? Was it described at all besides having numbers?
I think it's easy for us to pick out the discrepancies because we're third parties. In the moment, in panic, information gets jumbled. How many times have we simplified something for explanation... There've been countless studies and surveys done about perception in the moment of events. People get robbed, get the descriptions all wrong for example.
I haven't listened to her 911 conversation, but this friend does sound suspect. And for the sake of argument, maybe she is a concerned friend and didn't set them up...but she has knowledge of someone or something. It sounds to me like these kids were screwing around--Johnny, at least, because I get the 'young entrepreneur' vibe from him--trying to make easy money by selling something, didn't keep it to themselves and so someone knew about it and decided to take it. It's terrible and sad, but not uncommon.
One more (probably stupid) question. I've seen you guys use the abbreviation 'bbm' a lot. What's it mean? Usually I can figure it out!
