I know it's not murder when it's by a rattlesnake but it is still a very sad song involving death. But, you are right if I'm gonna ask about a murder ballad I guess I need to put one that has an actual murder in it. But, the rattlesnake song is over the top sad lol Ok if we are gonna be picky lol Just kidding.

Olmie Wise is probably my fav and saddest. Not just lyrically but melodically. It was a true story of John Lewis and Olmie Wise from North Carolina in the US.
