Jan Nash is joining TNT’s flagship drama series Rizzoli & Isles as executive producer/showrunner. She will succeed creator/executive producer Janet Tamaro, who stepped down as showrunner in September, right after the series wrapped production on Season 4. One of the first orders of business for Nash and her writing team will be dealing with the death of Rizzoli & Isles co-star Lee Thompson Young, who committed suicide in August, during the filming of the second to last episode of Season 4. His death was not addressed in the final episodes of Season 4 and will be dealt with at the opening of Season 5. Rizzoli & Isles is TNT’s No.1 show of all time and the No.2 scripted series in the history of ad-supported cable television, behind only AMC’s The Walking Dead.
