A beloved member of the Breaking Bad cast has died.
Actor RJ Mitte—who played Walter White Jr. on the AMC show from 2008 to 2013—died in Brownsville, Texas, his rep told Deadline Oct. 12. He was 34.
“It is with profound sadness,” the rep said, “that we share the tragic passing of beloved actor, philanthropist, and passionate disability rights advocate RJ Mitte.”
His cause of death was not confirmed.
Mitte rose to fame playing the son of Bryan Cranston’s character on Breaking Bad, bringing his own experience with cerebral palsy—a group of condtions that affect movement, balance and posture, per the Mayo Clinic—to the character.
He also advocated for disability rights offscreen and served as president of The Mitte Foundation—which aimed to improve the quality of life of Texans—as well as an ambassador for United Cerebral Palsy.
Following his stint on Breaking Bad, he landed roles in The Oak Room, The Recall, The Guardians of Justice and more.
