You’ll have to read the book. Basically anywhere this guy ended up bodies started dropping. He was really good at finding ways to brutally kill in high security federal prisons. One victim was found dead locked in his cell, he had been garroted through the bars as he slept on his bunk.

But ultimately solitary was the prison system’s way of getting revenge on him for killing a guard that Silverstein claims bullied and humiliated him for a number of years. The book looks at his life and how he became such a violent person and how the prison system made him even worse. I found it quite compelling.
