There's bad news and even more bad news awaiting Law & Order fans this morning. The bad news: A major character is leaving NBC's long-running drama. And the even more bad news: It ain't Elisabeth Rohm's Serena Southerlyn. According to The Hollywood Reporter, Jerry Orbach — who spent 12 years on the beat as Det. Lennie Briscoe — will depart the show at the end of the season. However, there's buzz that the veteran actor may take a role on the upcoming fourth installment of the franchise, Law & Order: Trial by Jury, which will follow a criminal case from arraignment to the jury's verdict.
