5 Most Evil Inmates of The Black Dolphin | Russia’s Deadliest Prison | The Prison Files

Deep in the frozen wilderness of Sol-Iletsk, near the border of Kazakhstan, sits an isolated fortress surrounded by razor wire and guarded by specialized canine units. This is Penal Colony No. 6, universally known as "Black Dolphin." It is the final destination for Russia’s most depraved serial killers, cannibals, and terrorists. Behind these thick stone walls, inmates are kept under 24-hour surveillance, forced to walk bent double in handcuffs, and are completely forbidden from sitting or resting on their bunks during daylight hours. In this chilling episode of The Prison Files, we unmask five of the most evil inmates to ever enter this living hell—men whose crimes were so horrific that the state designed an entirely separate level of psychological and physical isolation just to keep them contained. From terrifying cannibals and calculating predators who used lonely-hearts columns to lure victims, to monsters who documented their heinous sprees in private diaries, we break down their harrowing profiles, their psychological motives, and the brutal daily reality of serving a true life sentence inside Russia’s ultimate maximum-security cage. Watch until the end to understand the extreme measures the facility uses to ensure that once an inmate enters Black Dolphin, they only leave in a coffin. Stay sharp, stay vigilant.
