I had a similar experience in my motorcycle days. Very weird circumstance as I was a photographer at a friend's wedding, and that very night, one of their guests had a fatal motorcycle accident in town and they even stopped at the accident site to make sure it wasn't me. They found out after the honeymoon that it was another one of their friends. I even had a picture of the guy at the wedding I had taken just hours earlier.
But yeah, they didn't clean up the blood stain there, either. It was a 3 lane road and it was right down the middle. I just didn't ride down that middle lane, but it gave me chills to pass it. And it was right on one of my main routes as well.
