Leon Czolgosz shot President William McKinley on 6 September 1901 at the Pan-American Exposition in Buffalo, New York, firing two shots from a revolver he had concealed inside a handkerchief. McKinley lingered for eight days before dying of his wounds on 14 September.
Czolgosz's trial opened on 23 September. The jury took less than an hour to find him guilty, and on 26 September he was sentenced to death. He was executed in the electric chair at Auburn Prison on 29 October 1901, and prison officials later poured acid into his coffin to prevent the grave becoming a shrine.
Czolgosz showed no remorse for the killing. From the scaffold he declared, "I killed the President because he was the enemy of the good people, the good working people. I am not sorry for my crime."
