Biography
Bartolomeo Vanzetti was an Italian immigrant and anarchist who was arrested in 1920 for the murder of a shoe factory paymaster and his guard in South Braintree, Massachusetts. The trial was marked by a climate of anti-immigrant and anti-radical sentiment during the Red Scare. The prosecution's case relied heavily on circumstantial evidence, witness testimonies that were later recanted, and the defendants' anarchist affiliations. Despite widespread doubt about his guilt, Vanzetti was convicted and executed in the electric chair on August 23, 1927. In 1977, Massachusetts Governor Michael Dukakis issued a proclamation acknowledging that they had been unfairly tried and convicted.
Daily Worker, June 3, 1926, page 1: A June 1 Boston report says the Massachusetts supreme court again refused a new trial after arguments rejected May 3; new defense evidence temporarily blocked the return to Judge Webster Thayer for sentence. The paper also alleges a staged bomb scare at the home of prosecution witness Samuel Johnson to prejudice opinion. That accusation is attributed to the newspaper, not independently established. These are developments in the existing South Braintree prosecution, not a fresh arrest or execution date.

Daily Worker, June 3, 1926, page 2: A Federated Press interview describes him at Charlestown prison, studying English and following labor disputes. It recounts his blacklisting after the 1915–1916 Plymouth Cordage strike and says he distrusted the commercial press. The narrative links his labor organizing with contemporary defense advocacy without creating a separate arrest from the earlier strike.

Daily Worker, June 15, 1926, page 1–2, 4: Reports describe a Chicago defense conference representing forty-two organizations and over sixty thousand workers, the defense’s use of Madeiro’s confession to halt setting an execution date, and a national appeal by Eugene V. Debs distributed by International Labor Defense. These are defense-campaign developments in the existing case; the planned trial campaign and threatened execution do not establish a new verdict or execution date.

Daily Worker, November 3, 1928, page 1, 7: Election-rally and Gitlow-speech reports describe continuing post-execution protest and newly publicized evidence, accusing Governor Fuller of possessing exculpatory material.

The August 26, 1927 issue describes preparations for the Sacco-Vanzetti funeral, including an official limit of two hundred mourners. The announced August 28 funeral and cremation were prospective in this report, not accomplished events at publication. The existing execution date is unaffected.

The International Labor Defense holiday roster in the December 29, 1925 Daily Worker lists this prisoner, printed as Batholomew Vanzetti, at Charleston Massachusetts. This documents confinement at the roster’s reporting time, without establishing an admission, transfer, release, new conviction or complete duration. Existing independently sourced custody chronology remains separate. Source: https://www.marxists.org/history/usa/pubs/dailyworker/1925/1925-ny/v02b-n297-NYE-dec-29-1925-DW-LOC.pdf#page=5
Labor Defender, August 1932, printed page 146 (PDF page 7): Upton Sinclair's retrospective Because We Were for the Poor describes Vanzetti brought to trial shackled between deputies and placed in a steel cage, global protests, and a pre-execution letter to Dante Sacco. The account and reproduced historical headlines are post-execution advocacy, not new custody. The letter's seven years, three months and seventeen days is retained as quoted retrospective language, without replacing independently established arrest, execution or service dates.

The Socialist Call, June 26, 1937, page 9, invokes Sacco and Vanzetti in its critique of the Supreme Court's failure to protect radical defendants. This retrospective advocacy reference creates no additional case or change to the documented executions. Source: https://www.marxists.org/history/usa/pubs/socialist-call/call%203-119.pdf
The September 30, 1922 defense report described a prison interview with William D. Dobson, who claimed he and Fred Digney committed the Braintree crime. The defense argued that its trial prosecution had promised but failed to connect a stolen Buick to the two Italian defendants. These are contemporary defense allegations, not a new judicial disposition. Workers’ Dreadnought, September 30, 1922, original PDF page 4.

1920s custody-date review: The Massachusetts Supreme Judicial Court's historical exhibit records the death sentence on April 9, 1927, and execution at Charlestown State Prison on August 23, 1927. The latter is a death-in-custody date, not a release. Existing arrest and initial detention dates are unchanged.

The January 28, 1924 issue of The Daily Worker individually listed Bartolomeo Vanzetti among the political and class-war prisoners at the state prison at Charlestown, Massachusetts, in an appeal to fund newspaper subscriptions for imprisoned people. This is a contemporary custody observation; the publication date does not establish admission, release, or a total period served.
The Daily Worker of December 17, 1924, page 5, individually lists this prisoner among its political and class-war prisoners at Charlestown State Prison. This fills the blank institution using the printed roster in conjunction with the existing case biography. The publication date is an observation, not an admission or release date; no duration is inferred.

Contemporary labor and defense account, August 1925
Thurber Lewis’s report of the June 28, 1925 founding conference of International Labor Defense names Sacco and Vanzetti among the imprisoned workers for whose unconditional release the organization called. This is contemporary evidence of the existing imprisonment and defense campaign, not a new case or a precise admission, release, or actual-served duration.

The issue reports anniversary defense demonstrations in New York and Boston and arrests of three Boston memorial speakers. It connects the campaign against the Atlanta six’s threatened executions to memory of Sacco and Vanzetti. These are posthumous defense and protest events, not fresh personal custody.
The issue publishes Debs’s defense appeal, Art Shields’s report on the pending new-trial motion, and signed May 1926 prison letters. It discusses Madeiros’s confession and earlier witness repudiations as defense evidence, while describing six years already held and continuing danger of execution. The prosecutor’s wish for sentencing in July is prospective, not an accomplished sentencing date or death. These accounts do not establish a new custody interval or final duration.
