Casey Anthony, is this how she killed Caylee Anthony?

Good Theory..wouldn't be surprised.. anything is possible with that Evil Woman, I believe Casey killed Caylee with chloroform and duct tape. I think that Zenaida was Casey's code name for chloroform. She had investigated the chemical, months before Caylee died. Everytime Casey wanted to party without Caylee being around, she would say the nanny Zenaida (chloroform) would be watching the child, and drug Caylee, and place her in the trunk for several hours. Perhaps it started getting too risky for her with the drugging and getting back to the child before she arose.This final time, Casey also placed duct tape on the child's mouth and nose, and placed her in a bag in the trunk of her car. And there the poor child lay dead for days, before Casey removed her
