In reference to Perper looking at her mouth area...I suggested an aerosol spray or nebulizer machine which gets the stuff right to the lungs and into the bloodstream. It's the new "quick response" to the slowness of getting liquids/pills into the system. It seems like the REAL time that she was last seen alive is when Taz and Howard went to breakfast.....and KE had SUPPOSEDLY left.
Perper was in particular asking about alcohol swabs. I don't know exactly what that was about but given that the "looking at the mouth" thing came out i found it interesting because someone on tv mentioned he was looking at an area of the body that he hadn't looked at as an an injection site yet.
Now about your nebulizer theory, is that stuff undetectable at autopsy? If so, you may be onto something.
WRT KE, what would her motive be to kill Anna? We already know what HKS's were?
