I know your pain, I had a uncle who was more like a big brother that did the same and we still do not know why and it was 25 years ago. Unfortunately he never got to see my 37 done as he was helping me work on it when he did what he did and it sat for ten years before I started back on it and it took me too long to complete it that my dad died from natural causes before it hit the road but he did see it move on its own power. Just writing this and thinking about what my uncle did still hurts even after so long so this is all I am going to say but I know how you feel.
