Surely smothering is a guess?
Why the duct tape afterwards then?
Because she could not get caught with a smothered baby.... a drowned baby.. why not call 911? Drugging.. very risky... live baby in the trunk.... very risky. Cholorform only works for a little bit. If she tape her mouth prior to drugging.. then she would be careful that it would be able to come off after Caylee woke up. Have you ever seen a baby kick and scream? Even with tape, Caylee could have made muffled sounds and a ruckus with her feet by kicking the trunk lid.
Casey spent her days spinning lies. Building some upon others that she started months before.
As OSCO documentation shows, she had already had a "fake nanny".
for the past 2 years. If she did not already have a lie about the nanny or the sitter.. then she could not have "blamed it on the nanny." She also already had the lie in place about "working."
Once she was done smothering the baby, and realized what she had done... She would simply blame it on the nanny kidnapping her.
She purposely does not place the tape on Caylee's mouth carefully. After all, that is what a kidnapper would do. Right? However, she put the sticker on the mouth because it was "mommy's kiss." She had to be at Tony's soon. She knew she had to continue to act "normal" and carry on. If not, nobody would believe her "nanny kidnapping" story. Even in this scenario, she could have just stuck Caylee in the trunk -dead and taped her mouth and bagged the baby on the 17th and/or 18th. Of course, after getting ideas from her movie watching.
If she had a smothered baby at home, then she had to keep it from EVERYONE. Because then it would blow her lie about working and having a nanny. This also covers the no shoes and the doll in the car. If she drugged caylee and put her in the car.. why not put the doll in there with her?
Drugging a baby and putting her in the trunk is risky business. She would not have been so carefree with Tone and BB or the apt watching KIDNAPPING MOVIES. Tone not once in his interviews, after the police found chloroform was he asked if she went to her car that night during the movie, after the movie, etc.. She was carefree because.. everyone lives - everyone dies. Caylee was gone and she could do nothing about it. Her "Nanny did it" alibi was already in place in her mind. Might as well enjoy herself. Besides if her mother would have only watched her and not kicked them out... Caylee would not be dead. She actual feels a sense of freedom now both from Caylee and her mother.
Evidence shows she ramped up the "Caylee is with the nanny" story after June 16th with her mother, Amy, Jesse, Ryan, Tone... she could have easily kept telling Amy, Jesse, Tone and friends that Caylee was with her mom and her mom put her in a DAYCARE. She ramped up the story because if she did it caught.. her nanny kidnapping story was in place.
