Chicago P.D. Is Cutting A Series Regular Ahead Of Season 13, And I Just  Hope The Exit Is Handled Better Than Another MIA Character | Cinemablend

In a notable casting shake-up for Chicago P.D., Officer Kiana Cook, portrayed by Toya Turner, is confirmed to exit ahead of the upcoming Season 13, hinting at significant changes within the Intelligence Unit.

Turner, who joined the One Chicago franchise in July 2024 as a regular, shared a heartfelt farewell on her Instagram in June 2025. “My time on Chicago P.D. has come to a close,” Turner wrote, adding that the role “challenged me, sharpened me, & revealed what I’m made of… Next chapter.” She also expressed gratitude toward “ChiHards” for their support.

Introduced during Season 12, Officer Cook transitioned from tactical operations to patrol before being recruited to Voight’s Intelligence Unit. Her character’s strong moral compass and dedication made her a fan favorite, making the exit unexpected.

According to reports from Deadline, the upcoming season will introduce a new female series regular: an ATF Task Force officer with a military background, described intriguingly as a “loose cannon”. This shift hints at fresh storylines and evolving team dynamics.

The departure also raises questions about how the writers will justify Cook’s exit narratively. The Season 12 finale left plot points unresolved, and creative decisions appear aimed at opening new paths for character development.

With the show gearing up for a fall 2025 premiere, speculation is rife on how Cook’s absence will impact Voight’s close-knit team. Longtime cast members like Jason Beghe (Voight), Patrick John Flueger (Ruzek), Marina Squerciati (Burgess), LaRoyce Hawkins (Atwater), and Benjamin Levy Aguilar (Torres) remain. The addition of a more unpredictable ATF officer promises to shift the unit’s dynamic for Season 13.
