K I am coming in late....My GUESS would be that KC used choloform (if she did) on little precious Caylee BECAUSE it has been outlawed for so long she figured that noone would even think to run a tox screen on choloform IF Caylee is ever found. Just my guess, with her elaborate lies, and the details she goes into she isn't stupid by any means. Yes she is evil, and cunning and munipulative and a liar, but not stupid in the general sense of the word. No defense coming from me on KC....and on the subject of the ponderance of whether she thought about killing her parents? IMHO I just don't see that, look how mommy coddles and protects her, again, she is not stupid..........
