The Story

From May 1918 to October 1919, a killer attacked at least a dozen people in New Orleans and surrounding areas, often chiseling through back doors to reach sleeping Italian grocers. A letter to newspapers claimed to be the Axeman, threatening a jazz-filled night when no one would be harmed. At least six died; the killer was never identified.
