The Strategy Behind the Guilty Plea: Double Jeopardy Motion
The federal guilty plea was entered without a negotiated sentence agreement with federal prosecutors.Legal analysts note that entering a guilty plea to federal stalking charges allows defense attorneys Karen Friedman Agnifilo and Marc Agnifilo to invoke New York Criminal Procedure Law § 40.20 (New York State Double Jeopardy Law).
Within minutes of the federal plea, Mangione’s defense team filed a formal motion seeking the full dismissal of the Manhattan District Attorney’s state murder indictment.Manhattan prosecutors stated they are prepared to aggressively fight the dismissal motion to keep the September murder trial on schedule.
