A notorious inmate dubbed “the most dangerous prisoner ever held in the US” has spent an unprecedented 36 years in solitary confinement, marking a record in the nation’s federal prison system. Thomas Silverstein, known as “Terrible Tom” or “America’s most dangerous prisoner,” was a seemingly ordinary-looking man whose smile belied his capacity for extreme violence. His criminal exploits, including multiple murders and leadership in a notorious prison gang, necessitated the establishment of the high-security “supermax” prison to contain individuals of his caliber.
Silverstein, who lived 67 years, spent the last 42 of them behind bars, with 36 years in solitary confinement under strict conditions, including periods of no human contact. His actions, such as the killing of correction officer Merle Clutts, led to his isolated treatment within the prison system. Silverstein’s criminal history includes the murder of two other inmates before the fatal encounter with Clutts, demonstrating a pattern of extreme violence.
Following the gruesome incident at Marion prison in Illinois, where Clutts was murdered, Silverstein was transferred to a prison in Atlanta with stringent security measures, including a “no human contact” designation. The subsequent lockdown at Marion prison lasted for 23 years, prompting the establishment of the federal “supermax” prison in Florence, Colorado, to house the most dangerous offenders in the federal system, including high-profile criminals like Joaquin ‘El Chapo’ Guzman and Dzhokhar Tsarnaev.
Silverstein’s descent into violence began in his youth, marked by repeated encounters with law enforcement leading to his eventual incarceration for armed robbery. His association with the Aryan Brotherhood, a notorious prison gang involved in various criminal activities, further shaped his criminal trajectory. Despite his violent past, Silverstein’s correspondence with author Pete Earley revealed insights into his complex persona and the impact of his years in prison on his psyche.
The death of Silverstein in 2019 at the age of 67 brought an end to a tumultuous life marked by violence and isolation. While his treatment in prison was deemed harsh, officials cited the absence of viable alternatives due to the lack of the death penalty. Silverstein’s legacy as one of the most dangerous inmates in US prison history continues to raise questions about the management of high-risk individuals within the correctional system.
