Kelley Mack, widely recognized for her role as Addy in “The Walking Dead,” passed away over the weekend at the age of 33, as announced by her family. Her sister Kathryn shared heartfelt tributes on social media, expressing the deep loss felt by those who knew her.
Mack, born Kelley Lynne Klebenow, died peacefully on Saturday evening, surrounded by her family after a battle with diffuse midline glioma, an aggressive form of central nervous system cancer. Her family revealed that Mack was diagnosed earlier this year following a series of alarming symptoms, including severe pain that led to emergency MRIs revealing an abnormal mass in her spinal cord.
In her previous posts, Mack shared her gratitude for the support from her family and boyfriend, stating that her experiences had drawn her closer to her faith. She often expressed the emotional toll of her condition, but also the small victories she celebrated during her treatment, such as being able to walk up the stairs after a period of intense difficulty.
Her sister’s tribute highlighted Mack’s bravery and the love she shared with everyone. “She would want you all to know how much she loves you,” she wrote, conveying a strong message of Mack’s spirit and resilience. The family shared that they have felt her presence in nature, including signs like butterflies, symbolizing her lasting connection with loved ones.
Kelley Mack’s passion for storytelling began early in life when she received a video camera as a gift. She made her mark in the entertainment industry not only through her acting roles—appearing in “Chicago Med” and an episode of “9-1-1,” as well as upcoming films like “Mr. Manhattan,” “Delicate Arch,” and “Universal”—but also through her work in commercials and voice-overs.
Her family will hold a celebration of life in Ohio on August 16, where friends and admirers can gather to remember a creative and inspiring individual whose warmth and enthusiasm touched many lives. Mack leaves behind her family, friends, and countless fans who will remember her love for storytelling and the joy she brought to those around her.
