I would like to say, first of all, that my mind is getting boggled (easily done) by this thread. There are very smart people here.
Points being established here:
1..Car chase
2...July 3rd.. male at Anthony house w/kc and the phoney ploy to get CA out of house and to universal making CA EXTREMELY MAD, I am sure.
3...gas cans and George's stories.
Wouldn't the tow guy know if they were there? he didn't say they were.
As this moves forward and theories start to form, I am leaning to the possibility that Caylee was in the trunk on July 15th. At first I dismissed it because of all the heat and I kept saying it was impossible to keep a body that long. However, the smell is still in the car. It has been 5 months and the liner has been removed. This screams a cadaver was in that vehicle for a very long time.
If this theory holds, then what you are saying fits it and would be the reason for him to say he was near the trunk on the 24th to dispute the smell, thus protecting his daughter.
