Federal judge Margaret Garnett said Mangione would stand trial in October if she eliminates the death penalty as a possible sentence, as the defense has sought. Otherwise, she said at a hearing last week, Mangione would stand trial in January. The Manhattan district attorney’s office said there are “significant state interests” in putting Mangione on trial sooner. “Federal law supports our request that we proceed first and our right to a speedy resolution of this case would be severely compromised should the federal trial proceed first,” he said. “It is entirely natural then that the state case would proceed to trial prior to the federal case,” Seidemann’s letter said.
