“It is with indelible sadness that we are announcing the passing of our dear Kelley. Such a bright, fervent light has transitioned to the beyond, where we all eventually must go,” read a post by Mack’s family on Tuesday. “Kelley was known for her warmth, creativity and unwavering support for those around her. Her infectious enthusiasm and dedication to her work inspired countless others in the industry and beyond.”
“Kelleyโs legacy will live on through her contributions to film and television, and in the hearts of those who loved her. She will be deeply missed by forever remembered for her talent, kindness and vibrant spirit,” the statement concluded. Mack is survived by her parents, Kristen and Lindsay Klebenow, her sister Kathryn, and her brother, actor Parker Mack. She also leaves behind grandparents Lois and Larry Klebenow and boyfriend Logan Lanier.
Some of the first comments on the announcement came from Mack’s co-stars, including Alanna Masterson, who played Tara Chambler on The Walking Dead. “What an incredible human. So proud to have fought alongside her in our final episode together,” she wrote. Mack was also known for playing Penelope Jacobs on Chicago Med, and for several prominent ad campaigns she narrated.
Mack’s character Adeline, a.k.a. Addy, was a survivor of the zombie outbreak on The Walking Dead who lived in the Hilltop Colony. She had been a child at the time of the outbreak, meaning she lived about half her life in the post-apocalyptic community. Still, she showed surprising maturity for her age and experience, helping to balance the reckless personalities of other young people in Hilltop. She even shared a heartfelt moment with Daryl Dixon (Norman Reedus) before leaving the show.
Friends and fans continue to share their condolences and fond memories of Mack on social media as news of her passing spreads. For those interested in revisiting Mack’s work, The Walking Dead is streaming now on Netflix, Pluto TV, The Roku Channel, Sling TV, and Philo.
