Jeffrey Dahmer
It is widely believed that Jeffrey Dahmer is one of the most horrific serial killers in the history of America. Seventeen men and boys died between 1978 and 1991 as a result of his actions. As a result of confessing to the assault, death, dismemberment, and eating up of many victims, the killer received 15 life sentences in succession in 1992, but only survived for two years.
The fact that Dahmer did not receive the death penalty for his vile acts undoubtedly makes you curious about how he ended up dead. At the Columbia Correctional Institution, two years later, in 1994, a fellow inmate stabbed him to death when he was apprehended after a potential victim overpowered him.
