Producer Dick Wolf said he looked forward to creating "another interesting and memorable character in the Law & Order universe." Previous ADA Casey Novak (played by Diane Neal) left because of her over-aggressive tactics to nail a suspect and the ADA before that, Alexandra Cabot (played by Stephanie March), went into witness protection.
