On March 6, 1933, Herman Klink, a 40-year-old mentally ill man, shot 11 people in Cleveland, Ohio, United States, with a .22-caliber rifle.

[4] After arming himself with a .22-caliber rifle, Klink walked out of his Whitman Avenue home and shot a man in the shoulder.

[5] Klink proceeded on foot to West 38th street, where he mortally wounded Herman Pahler, a patrolman directing traffic in front of St. Mary's Catholic School, after shooting him in the abdomen, groin, and legs.

As Albert Marquis, 67, and Joseph Sapko, 22, ran for cover in opposite directions, Klink shot them both in their abdomens.

[12] Eight months prior to the shooting, Klink was fired from his job as a woodworker because his employer believed he posed a danger to his colleagues.
