Kelley Mack Dies at 33 : The entertainment world is reeling after the tragic loss of Kelley Mack, the actress best known for her role in AMC’s global phenomenon The Walking Dead. At just 33, Mack passed away peacefully in her Cincinnati hometown on August 3, 2025, after a courageous battle with glioma—a rare tumor attacking the brain and spinal cord. News of her death, confirmed via a heartfelt CaringBridge statement and her Instagram, has sparked an outpouring of grief from co-stars, fans, and cancer advocacy groups alike.
Who Was Kelley Mack ?
Born Kelley Klebenow, Mack grew up in Cincinnati dreaming of Hollywood. Her breakout role came in The Walking Dead’s intense Season 9, where she played a resourceful survivor in a post-apocalyptic world overrun by zombies. Though her screen time was brief, Mack’s performance left a lasting impact. As showrunner Angela Kang recalled: “Kelley brought raw authenticity to every scene. She made audiences believe in humanity’s resilience.”
Beyond TWD, Mack appeared in indie films like The Unseen (2020) and theater productions, earning praise for her versatility. Off-screen, she advocated for mental health awareness and animal rescue—passions that defined her as fiercely as her acting.
