R.J. Mitte, best known for playing Walter White Jr. on AMC’s “Breaking Bad,” dies at 34, according to statements from his representatives and authorities. Reports say he died in Brownsville, Texas. An immediate cause of death is not disclosed in the accounts, while one report notes that an autopsy is expected.

Multiple outlets describe Mitte as living with cerebral palsy and crediting him with bringing authenticity to his role on the series, which ran from 2008 to 2013. Several reports also highlight his disability rights work, including advocacy and public engagement rooted in his own experience. Coverage mentions his involvement with organizations such as United Cerebral Palsy and Shriners Children, as well as leadership through the Mitte Foundation. Other articles focus on tributes and remembrances from castmates and colleagues following his death.

While the reporting differs on emphasis—some center on his on-screen character, others on his activism or reactions from fellow performers—sources broadly agree on the age, location of death, and his public-facing disability advocacy.
