Axeman serial killer

All murders by the ‘Axeman of New Orleans’ were racially motivated, but a less plausible theory behind these murders was that the killer wanted to promote jazz music. He primarily targeted Italian immigrants in New Orleans. From 1918 to 1919, he killed 6 people with an axe, which often belonged to the victims themselves. His now infamous letter which he sent out in March 1919 stated that he would spare the occupants of any place where a jazz band was playing. On that night, all dance halls reached capacity and amateur bands played jazz at hundreds of house parties and there were no murders that night.
