RJ Mitte, Breaking Bad star and disability rights advocate, dead at 34

Cameron County Justice of the Peace Cyndi Hinojosa told The Associated Press that she declared Mitte dead at about 1:30 p.m. at what she believed was his home in Brownsville, Texas.

She said she was unable to provide a cause, but an autopsy will be performed.

Mitte played Walter White Jr., the son of Bryan Cranston's chemistry teacher-turned-meth dealer Walter White on nearly every episode of the five seasons of the AMC show, which recently ranked as the best of the 21st century in a New York Times poll.

Diagnosed at age three, Mitte told The Associated Press in 2014 that his disability and the surrounding struggles with physical therapy, family problems and exorbitant medical bills — all key subjects on the show — made him better at his job.
