would chloroform appear in a toxicology screening? wouldn't the application of it around her nose and mouth be detectable at autopsy? Michael Baden will be all over this on Greta tonight.
I may try to watch Greta tonight, something I don't typically do, because that's a really good question about the chloroform.
Also, if the reports are right, that the broken basement window (it had been broken for a while) was covered in undisturbed cobwebs, then Karr is lying that he gained access to the house that way.
