That is awful. I was recently told by someone who works in a nursing home near us (recently sold by my church's synod to a private company) that active euthanasia took place there. A family had two parents, one in the home and one at 'home'. Both were bedridden and incoherent but very much alive and not in a PVS. They got a doctor to order a very large dose of sedation, none of the nurses would give it because they refused to kill a human being. So, family hired a private duty 'nurse' who administered the drug, the patient died. Then, the 'nurse' went to their home and took care of the other parent, who died the next night.
I know a doc who used to be a ME, next time I run into him I think I'll ask him if he knows this is going on.
