For the first time, I dreamed about this case last night... guess my brain was working overtime.
For some reason, and I would hate to point a finger at TL cause he does seem like a good guy, I have major red flags going up around him. Here's my train of thought:
1) TL is the last known person to see KC with her car, and the timeline is very strange because (a) IIRC his school schedule should have placed him in class during the 11:00 hour and (b) Amscot worker reportedly noticed the vehicle at 7:00 a.am - wouldn't someone have noticed a girl hanging around the car waiting for a ride until 11:00ish?
2) The New York connection - IIRC KC claimed that "the nanny" is originally from New York/ New Jersey, TL took a trip to New York 6/30-7/5, AH stated that KC was overly giddy about TL coming home (could TL have promised to be bringing Caylee home and that made KC giddy?)
3) In KC's conversation with 911 operator, she claimed that she was looking for Caylee through other sources. Sounds like someone was helping her look for the baby, or at least promising to bring the baby back. She told CA that she just needed one more day. Why? What was scheduled to happen on 7/16?
4) After being in TL's possession between the time CA picked up KC and the time that LE came back to pick up KC's cell phone, all of KC's text messages and call history were wiped from KC's phone (remember, there was no forensic info available from KC's phone); also, when AL picked up KC's laptop it was plugged in, on, blank screen, and all of KC's email messages are missing. KC couldn't have deleted these herself because she was surprised with her mother showing up. Why didn't KC grab her cell phone when CA made her go back inside and said get your stuff?
5) During the jailhouse call with LA/CA/Kristine, KC was adamant that she must talk to Tony. Why, in the midst of all this, would she be so concerned about talking to a guy she just started dating? It's totally off, and LA thought so, too.
Now, I know this all feeds into the kidnapping theory which doesn't jibe with the decomposition evidence. I don't have any explanations here... just my gut feelings. And I think that if KC confided in anyone before 7/15, then it was her new boyfriend TL, with whom she spent all of her time. These are just some things I question....
