My opinion is that the over kill of duct tape was used to silence and/or cause of death. Again, my opinion was that Casey lost her temper but knew exactly what she was doing when she ended Caylees life.
In fact, I believe it was a pleasure for her to take the child everyone loved out of the equation given it seems as though the family was disappointed in the way Casey had chosen to live her life.
Casey had to have known duct tape on the remains had they ever been recovered, and it helped her invent her story, a spin off of the convenient nanny tale she had been throwing out for some time. Pin the crime on a fictitious character they would never be able to bring in.
I don't know how the defense could argue a kidnapping.
Casey claimed said imaginary nanny thought the world of Caylee. Casey also claimed "Zanny" didn't think Casey was a fit mother, so why then would a fake nanny go to the effort to kidnap this little girl "teaching her mother a lesson", eventually killing the child she thought neglected, as well as such a great kid? :waitasec:
Another example of Casey not really thinking too far ahead while she runs her mouth.
