Mark Carrigan, the shoe-cutter, was next. From his window on the third floor of the Hampton House he had watched the paymaster and the guard go down the street; then he had heard the shots and seen the car cross the tracks with the gunman crouched in the front seat. But from that glimpse Carrigan had not been able to identify the defendants in the Brockton police station and he was not now able to identify them in the courtroom. So far the trial was going in the routine manner that Katzmann had planned. These early witnesses were not expected to identify anyone. They were there merely to set the scene. Something more, however, was expected of Jimmy Bostock, the repairman, who had talked with Parmenter and Berardelli at the crossing, had seen the two men fall, and afterward had held the dying guard in his arms. The getaway car with the Italian-looking man who was leaning out shouting had passed so close to Bostock on Pearl Street that he could have reached out and touched it. Nevertheless, when asked in the Brockton station if he could tell whether Sacco and Vanzetti were the bandits he had answered, “No sir, I could not tell whether or not they was, no sir.” On the stand Bostock testified that Berardelli usually carried a 38-caliber revolver. He had seen it several times, the last time the Saturday before the murder. He had joked with Berardelli about it and asked him if he carried it to shoot rats. The mention of the revolver seemed irrelevant—especially as nobody had seen it on April 15—and Moore objected. Judge Thayer held a conference at the bench. There Assistant District Attorney Williams revealed for the first time the Commonwealth’s contention that the revolver found on Vanzetti had been taken from Berardelli’s body by the man who shot him. When Lewis Wade was taken by Katzmann to the Brockton station he had pointed out Sacco as the wavy-haired man he had seen standing over Berardelli. At the preliminary hearing in the Quincy court three weeks later he was not quite as certain. “I don’t want to make a mistake,” he had said, looking at Sacco. “This is too damn serious, but he looks like the man.” Since then Katzmann had given Wade a pep talk and was now counting on him for a positive identification. Williams, leading the witness along, became stutteringly disconcerted when Wade balked, maintaining that although Sacco looked to him somewhat like the man who did the shooting, he “had a doubt.” Several weeks ago, Wade explained, he had seen a man in Damato’s barbershop who looked just like the man who had shot Berardelli. Since that time he had decided that Sacco was not the man. Williams managed to recover his composure, but though he did his forensic best, he could get no further in persuading the intractable Wade.
