I mean think about it. Casey duct tapes her then injects her then puts the siringe back in the plastic, then puts that in the gator bottle of cleaning solution, then puts the lid back on the gator bottle then puts the gator bottle in the disney bag then throws the bag? C'mon people, this did not happen. This is way too far fetched.
To me, this is much less far-fetched than a nanny nobody ever saw kidnapping a child, but the mother wasn't worried for 31 days. Or maybe she was, because she said later how dangerous Zanny and her crowd are, and that she was worried for her family's safety. But the nanny loved Caylee so much, and took such great care of her. Then the nanny also placed Caylee's decomposing body in KC's trunk without her knowledge, causing her to tell others that she hit a squirrel.
The nanny also had the same obscure brand of duct tape as the Anthony family, and somehow stole a laundry bag from the home to place the remains in. While she was in the home months earlier, she had searched the computer for chloroform, so she knew how to use it; unfortunately, she spilled some in KC's trunk. She managed to then sneak back into KC's trunk and remove the body, before dumping it in the anthony's own neighborhood.
Somehow, she managed to make it appear that she never lived in Sawgrass apartments, and she removed her phone numbers from all of the Anthony's phones and home. Thankfully, she was smart enough not to go back to Fusion during the time when KC was investigating, or the whole scheme could have gone awry.
In all seriousness, the chloroform is another defining link between KC's trunk and the dump site. Whether or not the syringe was the delivery mechanism is not known, but it seems to me ridiculous to argue that it might have been a different mix of chloroform in the bottle than in the trunk. Just how much chloroform is floating around Orlando anyway?
I'm sorry, I welcome your opinion and am glad you have found this forum to share it with us, but I cannot find any way that KC's mangled story is the most logical, with all due respect.
