Answer:
The key evidence against Sacco was that one of the bullets was said to have been fired from his gun.
Explanation:
Nicola Sacco was an Italian anarchist who, together with Bartolomeo Vanzetti, was arrested, tried, and electrocuted in Massachusetts on 1927, under the charge of stealing $ 15,766.51 from a shoe factory, the assassination of his accountant named Frederick Parmenter and a security guard named Alessandro Berardelli, despite much doubt of his guilt
The events took place in April 1920, with three berths. Both had alibi, but were the only accused of the crime. With Sacco and Vanzetti the police found weapons and ammunition; however, the ballistics test was confusing, without reaching consensus as to whether the bullets that killed the accountant and his security had departed from the weapon they found with Italian anarchists. The witnesses were also confused and contradictory, which made it even more difficult to find the truth.
