King Fisher
One the lesser-known but more notoriously violent gunslingers of the Old West was John King Fisher, who was in and out of prison from the age of sixteen. In the early 1870s, Fisher became known as a bandit when he started running with a group of outlaws who raided ranches in Mexico. Fisher was known both for his flamboyant style, which saw him wear brightly colored clothes and carry twin ivory-handled pistols, as well as for his propensity for violence. He famously gunned down three members of his own gang when a dispute arose of money, and then killed seven Mexican pistoleros shortly after that. In his most famous gunfight, Fisher is said to have taken on four Mexican cowboys single-handedly. After hitting one with a branding iron, he supposedly outdrew another and shot him. In his typical brutal style, he then shot two of the man’s unarmed accomplices. In 1884, Fisher was ambushed and killed, along with Ben Thompson, by friends of a man whom Thompson had previously killed in a gun battle.
This guy is not someone you want to make angry, I think.
Coffee inside once more...sorry about that!
