The accident happened two years ago. The first time I managed to get his car keys away from him he called the the dealer, told them he had lost his keys and they sent him a new set. He finally did a U turn in front of an 18 wheeler that smashed his car to bits. His only injury was a six inch gash on his left arm. I was only a week away from a hearing to have him declared incompetent when my brother moved him to Missouri and into a nursing home. He died three months later. A very sad, sad situation. I don't know the answers to these situations when people are a danger to themselves and others.
