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.
