Hendrix did not know who the old man was or that the he had any illness. It sounds like Hendrix fired 3 warning shots which the old man ignored and keep advancing on Hendrix when he was finally shot dead.

More likely he was a rotten shot as well as being reckless.

I can see how this could happen. I have a neighbor who has advanced Alzheimers. He is mute, still strong as an ox and wanders off. He has a crazed look in his eyes and grabs people firmly when he wants something. Occasionally, he will grab so hard he leave bruises.

People in the neighborhood know him and understand how to get him home. A new resident might see him as on drugs or trying to attack him.

It’s another sad part of a terrible disease.
