The conviction of Bartolomeo Vanzetti and Nicola Sacco for a payroll robbery in South Braintree Square that left two men dead, continues to be debated a century later. The subsequent investigation and trial remains controversial and the execution of the two men in 1927 was met with worldwide protests.

Historian and author Christopher Daley will discuss the case during a program at 7 p.m. Feb. 25 at the Thomas Crane Public Library, 40 Washington St. Daley will show period photographs of the major players in the case, the location of the robberies, the massive demonstrations, the old Charlestown State Prison where the men were executed and the massive funeral procession for the men down Hanover Street in Boston's North End. Many of the photos have never been published.
