My mother and uncle have the POA for my grandfather. He is still living at his home by himself and has Alzheimer’s. He has someone come to sit with him during the day but no one is with him throughout the night. Yesterday morning my grandfather was found on his hands and knees at the end of his driveway. A neighbor had seen him and helped him back to the house. As the grandson, I know that he should not be spending any time alone for any reason, but my mother and uncle are simply in denial about their father's condition and maybe don’t grasp the reality of what could happen. My question is, if he had wandered into the street at 3:30 in the morning and someone had run off the road and hurt themselves badly, could my mother and uncle be held accountable in any form because they know he should not be left alone in his condition and could that lead to them being claimed negligent if an accident occurred and someone was injured? Thanks in advance for your help and response.
