In the early evening of June 10, 1900, a 19-year-old Croatian immigrant named Vido Opusich was on a mission. He was searching the streets of San Francisco for John Petrovich.
Petrovich was a 45-year-old waiter, commonly known by his nickname, Napoleon. He worked at a coffee house on the corner of Sacramento and Leidesdorff streets. At last Opusich found him at The Dalmatia, a saloon at the corner of Stockton and Pacific streets. The waiter was slightly drunk when Opusich entered the saloon and spotted him standing beside the bar.
Witnesses told police Opusich approached Napoleon, snarling something in a foreign tongue. The waiter jumped and immediately moved toward the street but Opusich pulled a revolver from his pocket and shot him. The bullet passed through Napoleon’s hat and lodged at the base of his brain. But he did not collapse. Instead, he staggered out of the saloon and into the street. Opusich followed him, firing three more shots.
