_I told them that if I put my name to that paper that they had already drawn up for me ... I could see it meant a terrible disgrace for me. They told me no, that I was doing the grandest thing a woman could do, and that by doing what they wanted me to do I would gain the respect and friendship of everyone, and that my boy would not be ashamed to look upon me as his mother, and the evidence they had brought with them from Maine would not be submitted to the court or to the eyes of anyone, not even to my son.... Mr. Moore took me over to a small desk and laid the paper in front of me and told me to sign it. I told him I would not, for I did not realize what I was doing.... They dipped the pen in the ink and tried to pass it into my hand.... All the time I was crying and asking them not to force me to sign it. My son then said, “Mother, I want you to sign that paper, for it means a whole lot to me.” I do not seem to remember much what happened after that, only that someone put the pen in my hand and told me to sign it, and asked my boy to come over to me and help me. My boy came over and put his arm around me and said, “Mother, sign this paper and have an end to all this trouble, for you did not recognize these men”—meaning Sacco and Vanzetti—“and you will only be doing a terrible wrong if you send those men to the chair.”_ “I was like I was in a trance,” she later told Katzmann. * * * * * Perhaps the most crucial testimony offered in the trial, the deciding factor—if John Dever is to be believed—was the evidence of the guns and the bullets. If, as Moore was well aware, it could be proved beyond a doubt that the mortal bullet found in Berardelli’s body had not been fired from Sacco’s automatic, the keystone of the Commonwealth’s case would be demolished. In February 1923, with this in mind, he engaged Dr. Albert Hamilton, a New York expert who had testified in 165 homicide cases, to prepare the fifth supplementary motion, the Hamilton-Proctor motion.
