Do we know when Casey stole that money? For some reason, I'm under the impression it was long before June 15th and therefore was not 'new' news or something to fight about at that time.
I believe it was the third week in May iirc, however,
Two things were new imo.
one is the new bf TonE who stated that his apartment was no place for a little child just days earlier. Remember that CA had the previous week off so Caylee was with her all that time. But starting the 16th, CA was heading back to work, GA had a job, so he wasn't going to be available, thus no babysitter.
The other thing is the therapist who advised CA to kick Casey to the curb, which CA said she could not in good conscience do, however, I believe she was struggling with how to get her daughter to grow up.
I believe that if there was a fight on that day, and I believe that there was, it was instigated by Casey. It didn't even have to be about something important. AH said that Casey got upset a lot about petty unimportant things. One thing is obvious to me though, the new boyfriend didn't want Caylee there, unlike Recardo who apparently didn't mind. With GA's new job, Casey found herself either being a parent and growing up, or find someone to take Caylee off her hands. I believe she had exhausted all friends, neighbors, and JG's family, and it was time to grow up, or get rid of. She chose the latter.
She chose a guy she knew for a couple weeks over her child, and imo it's just that simple.
then the lying game player that she is took her mom for ride like you wouldn't believe and after a couple weeks, CA was worried sick about Caylee, but it was already too late. Caylee was no longer alive.
The cell phone pings imply that Casey was home the night of the 15th.
I believe the flood of phone calls on the afternoon of the 16th was not because something horrible had happened but because TonE was out of school, and she wanted to go hang with him. When she couldn't find a sitter, she chose murder, then without skipping a beat, went to rent movies with her new boyfriend.
