A few thoughts:
1.) The CNN article says that her friends have not been cooperative. Why? If we assume that the only people involved in this are Kayla, KK, and possibly the boyfriend, why are the others not speaking up? Are they friends with KK too and care more about protecting him?
2.) I would be interested in knowing if Kayla ever smoked pot or did any other drugs before 8/11. I am not very familiar with pot but if your body is too "weak" for it, can it kill you? If that was the first time she smoked it, could it of had a deadly affect on her?
3.) I've read a lot of articles about the case but I haven't heard anything about the boyfriend. It's just that KK dropped Kayla off in front of the home where the boyfriend was supposed to be. Was the boyfriend there? Was he planning on meeting her? I would think that if he was 100% innocent and his girlfriend never showed up, he would call her home phone (since she didn't have a cell) or try to contact her another way.
