Thank you all for the excellent advice I'm contacting Adult Protective Services this morning to discuss this with them and will also look into the other suggestions regarding law enforcement.
As a side note living in a retirement community of aging seniors has really been an eye opener for me as I have been astonished at how quickly these mental conditions can come on people. My neighbor, across the hall, a very well educated lady I enjoyed many a conversation with, came down with dementia in less than two months and now has a difficult time, doesn't leave her apartment anymore, has a caretaker and her family took her car away. She's in her early seventies just like the Alzheimer's guy. All I can say is if you own a home stay in it because my experience with senior living has been depressing seeing all the people on walkers, canes, wheel chairs, in declining health both mentally and bodily.
