Kelley Mack’s family is sharing more details about her untimely death.
Two days after it was revealed that the Walking Dead alum—who appeared as Addy in season nine of the AMC series—had tragically passed, her family confirmed in an Aug. 6 statement to The New York Times that she died from an aggressive tumor that attacked her central nervous system.
One day prior, Kelley’s sister Kathryn shared that she died on Aug. 2 at age 33.
“It is with indelible sadness that we are announcing the passing of our dear Kelley,” she captioned an Aug. 5 Instagram post. “Such a bright, fervent light has transitioned to the beyond, where we all eventually must go.”
Prior to her passing, Kelley (real name Kelley Lynne Klebenow) revealed that she was battling a rare type of cancerous brain tumor called diffuse midline glioma, which develops in the midline structures of the brain, such as the brainstem, thalamus and spinal cord, according to the Mayo Clinic.

As part of her cancer journey, she underwent a difficult surgery that required her to relearn how to walk.
"Due to the biopsy surgery on my spinal cord," Kelley captioned a January Instagram post that featured a picture of herself smiling from a hospital bed, "I have lost the use of my right leg and most of my left leg, so I now get around with a walker and a wheelchair.”
Two months later, the 9-1-1 alum shared she had been making progress on moving around on her own.
"I’ve been up and down these stairs now 2x in the past few days," she wrote along a March Instagram video of herself walking with the help of her boyfriend Logan. "It’s a big deal for me. (Life has also had its ups and downs lately am I right lol)."
Following her passing, Kathryn reflected on the impact her sister had—and continues to have—on others.
“Kelley has already come to many of her loved ones in the form of various butterflies,” Kathryn continued. “She will be missed by so many to depths that words cannot express.”
