RJ Mitte, known for his role as Walter White Jr. in the acclaimed series "Breaking Bad," died by suicide on Monday in Texas. He was 34 years old.

Mitte's former girlfriend, Saint Sasha, posted an emotional tribute on Instagram, sharing throwback photos of the couple and remembering the actor. "RJ was the first person to show me how a man is supposed to treat a woman," Sasha wrote. "He was the first partner to build me up and make me feel unstoppable. He had one of the kindest and rarest hearts I’d ever had the privilege to experience and he was still a friend. I can’t believe this is real."

She added, "Never in any lifetime could I forget him and how he made me feel. He was the first and last of his kind. Thank you for everything, endlessly, RJ. I love you, homie."

Mitte had been engaged to his girlfriend of five years, Kennedy Suarez, whom he proposed to on her 30th birthday in October 2025. "I’m thrilled to have found my person, my partner in life who makes me want to be better, no matter what we’re doing," Mitte told People at the time. "Kennedy is my everything, and I can’t wait to officially start our life together and see what adventures life takes us on next."

Mitte, who openly discussed his cerebral palsy, proposed at a charity event in Carlsbad, California, that supported United Cerebral Palsy of San Diego, where he served as an ambassador. Suarez had celebrated the engagement on Instagram, stating, "My 30th felt like a fairytale…. I have the man of my dreams by my side & we are doing what we love most – helping others."

Mitte portrayed Walter “Flynn” White Jr., the son of Bryan Cranston's character Walter White, in all five seasons of "Breaking Bad." His co-star Luis Moncada, who played Marco Salamanca in the series, shared that Mitte had seemed unusually down shortly before his death. Moncada told "TMZ Live" that he had reunited with Mitte at a charity golf tournament over a week prior and noticed the actor seemed "tired and sad" and "very conflicted."

In what is believed to be his final interview, recorded on Oct. 5 for "The Joe Vulpis" podcast, Mitte spoke about his future plans, stating he intended to keep auditioning and "living the dream." He remarked, "I tell people, you know, every dream could be a nightmare, too … but just keep living it, just keep pushing forward."
