_The understanding in this case between the agents of the Department of Justice in Boston and the District Attorney followed the usual custom, that the Department of Justice would help the District Attorney to secure a conviction, and that he in turn would help the agents of the Department of Justice to secure information that they might desire._ Weyland, West, and other agents attended the Dedham trial in the expectation of finding sufficient evidence against Sacco and Vanzetti to deport them as anarchists in case they were acquitted of murder. In the autumn of 1920, either West or Katzmann conceived the idea of planting an informer in the cell next to Sacco. West hoped to find out something about the Wall Street bomb explosion of September 16. Although all the clues in that bombing had come to nothing, the Justice Department held to its theory that the explosion was the work of anarchists. West and Katzmann talked the matter over with Feri Felix Weiss, formerly one of West’s agents. Weiss operated his own “Scientific-Secret-Service,” but still did occasional work for the Department’s Bureau of Investigation. He sent a letter to an informer, John Ruzzamenti, in Reddington, Pennsylvania, asking if he would be willing to help in getting evidence against two probable criminals. He might have to stay in jail for a few days, but success in this job might lead to bigger investigations, like the Wall Street explosion, with juicier expense accounts. The eager Ruzzamenti arrived on Weiss’s doorstep two days after Christmas. Katzmann, on meeting Ruzzamenti in his courthouse office, appeared bluffly cordial, helping him off with his overcoat and calling him John. He then explained his plan. Ruzzamenti would be arrested with burglar tools in the act of breaking into a house. The sheriff would see that he was placed in the cell adjoining Sacco’s. Ruzzamenti would act depressed for the first few days and say nothing, then try to strike up a conversation. Ruzzamenti objected to being tagged with a police record and when Katzmann could not change his mind, he suggested that Ruzzamenti go to Stoughton and see what he could ferret out there. They would arrange that he got some sort of job in the town, perhaps in a shoe factory. As an Italian he might even manage to rent a room from Rosina Sacco. Katzmann said he had reports that she was in an upset state. It should be easy to establish friendly relations with her. To this proposal Ruzzamenti agreed. Whether or not Katzmann was serious about it or was just thinking aloud, he soon afterward dropped the idea as well as any connection with Ruzzamenti. He and West and Weiss managed to place a more amenable informer near Sacco. The man, Antony Carbone, spent several days in the jail and managed to talk with Sacco at intervals but could find out nothing.
