When correctional officer Valentino Rodriguez first stepped behind prison walls, he wasn’t just starting a job, he was joining a brotherhood. What he didn’t know was that he was now bound by an unwritten code that would ultimately test his loyalty to his oath and his fellow officers. Valentino’s sudden death on October 21, 2020 would raise questions from the FBI, his family and his mentor in the elite investigative unit where they both worked. For more than two years, our colleagues with KQED’s investigative podcast On Our Watch have been looking into what happened to Valentino Rodriguez, because his story is part of something much bigger. He was a correctional officer at New Folsom prison, near Sacramento, where the reporting team has found use of force that’s off the charts, and a pattern of suspicious beatings. This week we bring you an excerpt from the first episode of the series.
