Coakley's rebuttal witnesses consisted of officers who had interrogated the prisoners at Camp Shoemaker. The rebuttal fared poorly, as Veltmann was able to elicit from them: that some of the accused men had not been informed they could refuse to make a statement; that some of the interrogations had taken place with an armed sentry standing guard; that very few of the prisoners' explanations that they had been afraid of another explosion had been included in the statements; and that the officers had emphasized portions of the interrogations that would satisfy Coakley's requirement for evidence of conspiracy. Coakley's last rebuttal witness testified on October 19, and the whole court took October 20 off to allow both sides to prepare closing arguments.
