For the purposes of this post, I’ve excluded the folks who 1) died in duels, 2) were killed in military engagements (although Crabb was shot after surrendering and could probably be counted) or 3) were killed by law enforcement in the regular course of their job (Terry, looking at you).

1) Alexander P. Crittenden – After a seven-year extramarital affair, Crittenden was shot by his jealous lover in front of his family in 1870. A full write-up can be found here.

2) John Yule – Most likely brutally murdered in Placerville in 1888.

STILL IN MYSTERY
The Story of the Strange Disappearance of John Yule

Placerville, April 23d. – El Dorado county, during the past week, has been the scene of considerable excitement, owing to the mysterious disappearance of John Yule, ex-Speaker of the Assembly and a well-known old-timer of this and Placer counties…

After leaving the mine, dressed in his ordinary clothes, Yule wandered into a saloon near by kept by Jack Burt, a noted resort of disreputable characters. Here he succumbed to the captivating smiles of one of the frail inmates.
