I am trying to triangulate a bit on when KC returned home on the 16th and fit it into the possibility that Caylee died in the car.
GA says he last saw Caylee around 12:50 PM when she and KC left for "work". Cell pings indicate they stayed in the vicinity. Desktop and laptop computer activity cease during this period of time, supporting the notion KC is not at the Anthony home.
Very light computer activity occurs between 1 and 2 PM on the laptop. Then very heavy computer activity occurs between 2 and 3 PM on the desktop. The activity seems to be indicative of KC being on the two computers and not GA. This further implies KC returned to the home just before 2 PM and had enough time to do a small amount of work on the laptop after returning, and later hitting the desktop. GA was not around, so he likely had left for work.
When did GA start work? I have heard 2 PM, and I have heard 3 PM. Travel time for GA was about 20 minutes, so unless he was doing errands before work, he would not be leaving until about half an hour before work. I think the computer evidence supports GA leaving the home before 2 PM, probably because his job started then on that day.
KC calls Amy at 1:45 and speaks with her until 2:21. Sometime between 1:45 and 2 PM, KC is back at her parents. Where is Caylee?
Now we can flesh this out with some speculation:
- Caylee falls asleep soon after leaving the A's because it is nap time. KC occupies herself with Tony texting somewhere near the A's, maybe Lee's...maybe the elementary school.
- KC calls Amy at 1:45, then while on the phone, heads back to the A's.
- KC and a sleeping Caylee arrive at the A's just before 2. KC grabs a few items from the car but is otherwise deep into her conversation with Amy. She sees a sleeping Caylee and notes to herself that she needs to come back out immediately and get Caylee and take her to bed.
- While inside Amy says something that prompts KC to flip open the laptop. Next she starts up the desktop. She and Amy talk and surf real time until 2:20 PM.
- KC is sucked into the computer by now and uses it heavily until JG calls a half hour later at 2:53 PM.
- KC and JG converse intently until KC gets a very rare call from GA at 3:04 PM. KC takes the call. Sometime during the conversation GA says "Caylee", and a little light bulb goes off in KC's head. "Caylee ..."
- KC gets off the phone with her dad as she rushes out to the car...
