A man known as “the most dangerous prisoner ever held in the US penal system” has spent 36 years in solitary confinement, marking the longest isolation period in federal prison history. Despite appearing unassuming in his mugshot, this individual, dubbed “Terrible Tom” or “America’s most dangerous prisoner,” is infamous for his involvement in multiple murders and leadership within a notorious prison gang.
Thomas Silverstein, who lived for 67 years, served 42 of them incarcerated, with 36 years spent in solitary confinement under strict conditions, including limited human interaction. His violent actions prompted the establishment of a high-security facility known as a “supermax” prison, designed for the most dangerous inmates in the federal system.
In a tragic incident at Marion prison in Illinois in 1983, Silverstein, aided by a fellow inmate, murdered a correction officer, leading to a prolonged lockdown at the facility. Subsequently, he was transferred to a prison in Atlanta with a security status of “no human contact.” This chain of events influenced the foundation of the federal “supermax” prison in Florence, Colorado, where Silverstein was eventually relocated.
Prior to this fatal event, Silverstein had already killed two other prisoners, demonstrating a pattern of violence within the prison system. Despite his troubled past and ties to the Aryan Brotherhood, a notorious prison gang, some individuals who knew him personally described him as more complex than his notorious reputation suggested.
Silverstein’s life ended in 2019 due to health complications following heart surgery. His treatment in prison was controversial, with some acknowledging its severity but citing the absence of viable alternatives given the circumstances. The federal prison director, reflecting on Silverstein’s case, emphasized the challenges of managing a dangerous individual without the option of capital punishment.
