I can't... While she may be a killer, a bit##, a sociopath, i do not believe she is cruel enough to hold Caylee down, and tape her mouth. it is dangerous, difficult, and un-necessary with all the drugs in the house. it only makes sense to me that she would subdue Caylee with drugs before putting the tape over her mouth and nose, where she would then go quietly, without fuss or muss. Even that Marine who allegedly killed his family, it comes out now, did not want to do it while they were full aware, but drugged them first, then strangled them. it is hard for us to comprehend the violence and impact of strangling someone who is conscious and struggling, all we have is the movies for reference. i do not believe even kc capable of this act, its just too much work.
