Mangione’s lawyer, Karen Friedman Agnifilo, called the district attorney’s request for a July state trial “unrealistic.” The defense will need the rest of the year to prepare for the federal trial, she said. “It is entirely natural then that the state case would proceed to trial prior to the federal case,” the prosecutor wrote, citing legal precedent. Under New York law, the district attorney’s office could be barred from trying Mangione on state murder charges if his federal trial happens first. Mangione has pleaded not guilty to federal and state murder charges; the state charges carry the possibility of life in prison. He is due back in court for a conference in the federal case on Friday.
