From July 8 to August 1, 1942, the trial took place in Assembly Hall #1 on the fifth floor of the Department of Justice building in Washington D.C. On August 3, 1942, two days after the trial ended, all eight were found guilty and sentenced to death. Roosevelt later commuted the death sentence of Dasch to 30 years in prison and the sentence of Burger to life in prison, as they had both confessed and assisted in capturing the others. Indeed, it was Dasch who approached the FBI, offering to turn the men in, which he then did. Burger was part of the plot to turn on the others and cooperated with the FBI extensively. The remaining six were executed in the electric chair on the third floor of the District of Columbia jail on August 8 and buried in a potter's field called Blue Plains in the Anacostia area of Washington.
