While Chicago P.D.’s leads like Hank Voight and Kim Burgess grab headlines, its supporting cast adds depth that keeps fans glued to NBC. Since 2014, actors like Jon Seda as Antonio Dawson and Elias Koteas as Alvin Olinsky laid early foundations, their departures—Antonio’s addiction spiral in Season 7 and Olinsky’s 2018 prison murder—still haunting the Intelligence Unit. By Season 12 in 2025, new and recurring players elevate the show. Toya Turner’s Kiana Cook, introduced in 2024, brings fierce energy as a patrol officer eyeing Intelligence, her clash with Voight in “Demons” (April 2025) sparking X debates over her loyalty.
Carmela Zumbado’s Officer Liliana Martinez, a Season 12 addition, blends street smarts with compassion, her mentorship under Burgess echoing the show’s theme of growth. Off-screen, Zumbado’s Chicago pride—she’s posted about filming near her childhood haunts—grounds her role. Recurring faces like Sara Bues as ASA Nina Chapman add moral friction, challenging Voight’s methods in courtrooms and backrooms. Fans on X praise Bues’ chemistry with Jason Beghe, calling their standoffs “Emmy-worthy.” Even smaller roles, like Jefferson White’s Officer Sean O’Neal, linger—his Season 10 betrayal as a mole crushed Atwater’s trust, a wound LaRoyce Hawkins says still shapes his arc.
These actors don’t just fill scenes; they humanize P.D.’s chaos. Turner’s Cook, for instance, tackles gentrification’s toll in a 2025 episode, reflecting Chicago’s real struggles. Their off-screen camaraderie—Zumbado and Turner joking at a cast bowling night posted by Marina Squerciati—mirrors the precinct’s family vibe. Supporting stars may lack Voight’s spotlight, but their grit, from Olinsky’s sacrifice to Cook’s ambition, proves Chicago P.D. thrives on every player, making District 21 feel alive and fans fiercely loyal.
