I've read just enough about the case to be surprised - I know, I shouldn't be - when some random person makes some kind of categorical statement about who did what to who, and who didn't, and why, and why not. The contemporary accounts are contradictory, as are the later statements from those who were alive at the time and supposedly close to the case, and the later researchers are not in agreement, so .... If you have family lore passed down from the time and place of the events, that's one thing - but if you're just someone who heard the song and saw something on TV once ... well .......
