Overview

Between May 1918 and October 1919, an unidentified serial killer attacked at least a dozen people in New Orleans and its surrounding parishes, killing at least six, often breaking in at night and striking sleeping victims with an axe found on the premises. Many of the victims were Italian-American grocers, which led police to theorize Mafia or 'Black Hand' involvement, though attacks on non-Italian victims weakened that theory. In March 1919 a letter purporting to come from the Axeman was published in New Orleans newspapers, claiming he would spare anyone with a jazz band playing at a set hour; the city responded with jazz parties and no murders occurred that night. The attacker was never identified, caught, or charged, and the case remains unsolved.

Where it stands

The case remains officially unsolved; the killer was never identified, arrested, or charged, and Country Roads Magazine concludes 'the mystery remains unsolved.' According to Wikipedia, scholar Richard Warner identified Frank 'Doc' Mumphrey (1875–1921), who used the alias Leon Joseph Monfre/Manfre, as the chief suspect. NOLA.com (The Times-Picayune) reports that a man named Joseph Mumfre, a previously convicted 'Black Hander,' was shot and killed in Los Angeles by Esther Pepitone, widow of the Axeman's apparent last victim Mike Pepitone, though this account is disputed and has never been confirmed as linking him to the murders. Some historians, including Miriam Davis, argue the famous jazz letter was not written by the actual killer.
