RJ Mitte, the actor who became known to millions as Walter “Flynn” White Jr. on Breaking Bad, has died at age 34.

According to authorities, Mitte passed away in Texas on Monday. His representatives confirmed his death.

The investigation into the circumstances of his passing is ongoing.

Mitte’s death follows a recent appearance in social media photos with Breaking Bad co-star Luis Moncada and shortly after the release of his final long-form podcast interview.

For generations of television viewers, Mitte will always be Walter “Flynn” White Jr.—the son caught inside the collapse of Walter White’s family as Breaking Bad grew from a dark cable drama into a cultural phenomenon.

He appeared in 56 episodes across the show’s five-season run, growing up in front of audiences while working alongside Bryan Cranston, Anna Gunn and the rest of one of television’s most acclaimed casts.

Mitte joined the series as a teenager and carried a role that could have been reduced to a plot device. Instead, Walter Jr. became one of the story’s moral pressure points—the son forced to watch the image of his father disintegrate in real time.

Mitte lived with cerebral palsy from childhood. His case was milder than his character’s, and he learned to use crutches and alter his speech for the role. He never treated that connection as a gimmick.

After Breaking Bad, Mitte used his platform to advocate for disabled performers to be hired for full, complicated roles instead of being kept at the edges of the industry. He worked with United Cerebral Palsy, Shriners Children’s and other organizations while speaking publicly about access, employment and representation.

Mitte had also announced his engagement to longtime girlfriend Kennedy Suarez in 2025. At the time, he spoke publicly about the joy of finding the person with whom he wanted to build his life.
