John Haggerty, construction supervisor, testifies that Antonio Sirio assaulted him on January 21, 1905 with a crowbar. Haggerty had been supervising around eighty laborers in the construction of an extension to Riverside Drive at 146th Street. The train that carried building materials from the dock to the worksite had jumped the tracks and Haggerty had directed seven workmen to lift the locomotive back onto the rails. One laborer, Antonio Sirio, had appeared not to comprehend his instructions and Haggerty had taken him by the coat and had pushed him toward the locomotive. Haggerty testifies that, approximately twenty-five minutes later, Sirio had hit him on the head with a crowbar. Other witnesses testify to the assault, describing the attack and the subsequent attempt by Sirio to flee the scene. Antonio Sirio, speaking through an interpreter, testifies that Haggerty violently struck him and kicked him and that he struck back with the crowbar in self-defense. Two witnesses, Luigi Mazella and Biagio Mazella, corroborate Sirio’s account that he struck Haggerty after the supervisor had attacked him. The jury finds Antonio Sirio guilty of assault in the first degree.
