I believe the following timeline works with the pings, interviews, and forensic evidence. I am leaving the "area of interest" vague for now until Bond gets confirmation that it has been searched.
Midnight to 2:50:00 PMAt AL or at least very close (could go to Target, for example). During early afternoon texts Matt C. to find out if he has any open apartments. Matt C. calls her back, says he does and will be around all afternoon. AL may not be home yet from school (last class is 1:00, but sometimes he stays to get additional work done).
2:50:00 PM to 3:05:00 PMDrive her car (Pontiac) to "area of interest". From AL's this would normally take less than 10 minutes, but she is not familiar with the back roads there, so she takes a route from the south that she is familiar with.
KC sends text to Matt C. - perhaps firming plans to see apartment. This text pings tower 48, supporting the notion she entered the "area of interest" from the south along a familiar route.
3:05:00 PM to 3:35:00 PMHide body. I have my doubts that the body was left in water at this location. Good images of the location indicate that getting to the water requires walking through a fair amount of marshy growth. I do not see Casey doing that while carrying a body that has already leaked fluids into her trunk. Rather, I think she found a spot next to the road with an opening into the woods that would allow her to hide the body in those woods under brush without having to carry the body too far.
Matt C. responds to KC text. KC does not have any outgoing texts or calls during this time.
3:35:00 PM to 3:50:00 PM Drive back to AL using same route she came in.
3:50:00 PM to 4:35:00 PM At AL. Cleans up. Discusses looking at new apartment, saying she has confirmed with Matt C. that an apartment is available and he can show it too them that afternoon. Also posts message on Facebook at 3:57, so may have been back at AL's even earlier.
4:35:00 PM to 4:40:00 PM Drive from AL to Crane's Landing, probably in Jeep.
4:40:00 PM to 4:50:00 PM Meet Matt / introductions / catch up small-talk / check IDs.
4:50:00 PM to 5:00:00 PM Matt shows AL apartment. KC does not have her ID with her, so she has to wait. During this time she gets two texts from Sean H. and sends one reply.
5:00:00 PM to 5:10:00 PM Discuss interest in apartment / say goodbyes. Of course the above set of details regarding the visit and specific amount of time is speculative, it seems reasonable in light of the fact KC went to high school with Matt and had not seen him in a while.
5:10:00 PM to 5:15:00 PM Drive back to AL
5:15:00 PM to 5:20:00 PM Gets purse / ID from apt. and borrows AL's Jeep. AL's interviews do not mention this. It would be interesting to know what she told AL as to the reason why she wanted to borrow it.
5:20:00 PM to 5:50:00 PMDrive to Chris S. Normally 20 mins, but I speculate that she takes a detour through "area of interest" just to be sure no one saw her and called police. This adds 10 minutes to the drive.
It also means she takes a back route to Chris S., driving down the S. Econlockhatchee Trail. This places her far enough east to have her cell phone ping tower 38, which I think had to happen enroute, about 5 minutes from Chris S.
5:50:00 PM to 8:00:00 PMAt Chris S. His interview says she was there 1.5 to 2 hours. I believe it was 2 hours or perhaps a little longer. The reason is that thunderstorms start in the area around 6:45 PM, and this tapers to light rain about 8:00 PM. I think she waited for the weather to ease up before leaving. Turns cell phone off when she arrives.
8:00:00 PM to 8:15:00 PM Drive to area of interest. After she leaves Chris S., she could have gone directly back to AL's. The ping at 9:02 PM from tower 46 could have occurred at his apartment.
However, I think she once again drove to the area of interest. Originally I felt she would have done this to perhaps improve the way in which she hid the body. However, it would have been quite wet and sloppy due to the thunderstorms. It may have still been raining lightly at that time.
So, at the risk of being very controversial, I think she simply sat in the jeep near the spot she left the body, and thought about what had happened over the past three days. If there was any time that she was alone, could have felt sad and perhaps said goodbye, this was it. Sunset was 8:25 PM and twilight 8:52 PM, at which point she finished whatever mourning she may have done.
8:55:00 PM to 9:10:00 PM Drive from area of interest to AL. Turns cell phone back on. Ping tower 46 as she drives up Goldenrod.
9:10:00 PM to OnwardAt AL.
In support of the above, note that Matt C. is on the witness list but Chris S. is not. I believe this is because Matt C's testimony will help LE establish the time in which Caylee's body is dumped, whereas Chris S's will not. While her driving to his house in AL's jeep provides food for interesting speculation, it had nothing to do with dumping the body.
This one has received attention although not in the media.
