Progress has been made...
My mother and aunt met with my grandfather yesterday along with the former employee and informed them that she was in fact a Former employee and has until tomorrow to pack and move out, he is moving up the hill to my parents house while a professional service cleans his home and/or until further arrangements can be made for his continued care.
My wife, son, and Monster in law (actually she's not bad, but we're her primary caregivers...)and I stayed until this was resolved, then piled into the car and made a 475 mile trip, arriving home at 23:45 Last night Including a stop for dinner and one for fuel. Dry roads all the way up to sillycuse from VA,
