The original cast member, whose character retired in season 15, will guest-star in an episode slated for May, titled “Fashionable Crimes,” in which Munch returns to weigh in on the case of a young model who claims she was preyed upon by a famous fashion house photographer. While the photographer had been on Munch and Fin’s (Ice-T) radar for some time, they’ve never been able to make a case against him until now.
