So, we are close neighbors and he’s a friend of dh. Today he came over to the backyard where dh was and just happened to mention the condition of his father’s diabetic leg. Which was starting to smell like rotten meat. Because it was. Dad currently is in surgery for an under the knee amputation.
The friend is disfavored by the poa brother whom he had to call to save dad’s life. If dad declines mentally, said brother would have no problem liquidating the house this friend lives in.
In hindsight, the situation was not a good set up. He probably wasn't able to handle a household, but he was cheap labor for the POA sister who rarely visited.
