The lamplight filtering through the haze and drizzle gave the streets of New Orleans an eerie pallor that October night in 1890. It was nearing midnight when Dave Hennessy, the city’s thirty-two-year-old police chief, left his office and headed home, escorted by an old friend, Captain William O’Connor. There had been threats on Hennessy’s life, but the popular and respected chief took them lightly. When the two men reached Girod Street, where Hennessy lived, the chief told O’Connor it was not necessary to accompany him any farther. The two men bade each other good night, and Hennessy headed up the damp and deserted street alone.
He had almost reached home when the silence of the night was shattered by the roar of gunfire. The shots came from a shanty on the other side of the street where a recently arrived immigrant Sicilian shoemaker was living. Hennessy was hit, but he managed to draw his service revolver and get off three or four shots as his attackers fled.
