Long story. Poking around on the internet, found the best synopsis I've seen yet of my Grandpa's murder. I finally watched the Unsolved Mysteries episode a couple of years ago. It was still hard to watch, all those years later. They never did solve it. I took the call from the sheriff's office about the burning car. My Dad wasn't home from work yet. (Pre-cell phone.) Christmas came and went, with no clue what had happened to him. He'd left presents for my sister and I, and a note saying he loved me in mine.
A few months later, when they called to say they had finally found him, I went downstairs to the piano and played Moonlight Sonata. It seemed appropriate. My Dad asked me to stop though. I could see why. That's a sad tale that puts things in perspective. You're welcome(?)
