Sacco and Vanzetti each offered evidence of an alibi. Sacco testified that on April 15, 1920, he had taken the day off from work and traveled to Boston to request a passport from the Italian consulate. Several witnesses testified that they saw Sacco en route to Boston or in Boston.
Sacco and Vanzetti proclaimed and defended their innocence even till the very end. Before the crime ever took place Sacco worked at the Milford Shoe Factory as an edge trimmer. Sacco was a hard worker; who supported his wife, Rosa, and his son, Dante. Vanzetti worked as a fish peddler. In May 1917, both left their jobs to go to Mexico and avoid.
