Brian Geraghty, who played Officer Sean Roman on the hit TV show "Chicago P.D.," left the series after Season 3. According to former executive producer Matt Olmstead, Geraghty decided to pursue other projects and wanted to focus on some of the productions he was involved in as a producer. Despite the departure, Olmstead spoke highly of Geraghty, describing him as a level-headed and decent individual. The actor's exit from the show was reportedly amicable, with both parties coming to a mutual agreement.
