I agree 100% with this. The autopsy only concludes the tape was placed before decomposition began, not premortem (perimortem? am still having my morning cofee...).
I said months ago I think she may have died in bed with KC. Being on several 'crunchy parenting' boards myself and learning, a risk for death during co-sleeping is the parent's alcohol and/or drug usage. That they may roll over and suffocate the child being unaware. KC may not be a very large girl, but she was 3-4x Caylee's weight.
I believe the trunk, the duct tape, and the chloroform are all staging agents from someone desperate not to be blamed for Caylee's death. Even if the death was not from cosleeping, or even intentional I still think these were staging because they all are CLASSIC associations with kidnapping. I think it's overthinking to believe she attempted to kill Caylee with duct tape over her nose&mouth, then used or previously used chloroform, then drove around with her in the trunk as seperately come up with plans. Kidnapping-scenario makes a much more reasonable explanation including the placement in the trunk. It's all staging and I know nothing more now after reading the report than I did before.
