3 Most Evil Inmates of San Quentin | Even Serial Killers Feared Them | The Prison Files

San Quentin State Prison, standing grimly on the edge of the San Francisco Bay, is California’s oldest and most notorious fortress—a place where the salt air meets the heavy weight of Death Row. In this chilling deep dive, we expose the dark history of three of the most infamous inmates to ever inhabit its iron-barred cells: a sadistic predator who terrorized a city, a master manipulator who led a deadly cult, and a "perfect" husband whose betrayal shocked the nation. These men represent the different faces of evil that have defined the walls of San Quentin for decades. From the terrifying reign of Richard Ramirez, the "Night Stalker," whose satanic brutality and complete lack of remorse turned the 1980s into a decade of fear, to the legendary Charles Manson, the puppet master whose psychological grip on his "Family" led to one of the most gruesome crime sprees in American history, and finally Scott Peterson, the man whose polished image masked a dark capacity for deception—these inmates made San Quentin a household name for all the wrong reasons. Discover the harrowing details of the lives they led inside the walls of California’s deadliest prison, the psychological profiles that baffle experts to this day, and the legacy of the crimes that landed them on Death Row. Watch to the end for a deeper look into the shadows of San Quentin—where the most dangerous minds were held, and where the echoes of their crimes still resonate today.
