James Allen Red Dog, a mixed Sioux and Assiniboine man, was a serial killer who was executed in Delaware after murdering Hugh Pennington in 1991. Red Dog had a troubled past, marked by poverty on the Fort Peck Indian Reservation and multiple convictions for armed robbery and murder. While he initially resisted a death sentence, Red Dog ultimately requested and accepted his execution, stating it was consistent with his warrior's code. His execution was met with controversy, as his attorneys tried to argue that he was not mentally competent to make such a decision. Despite his lawyers' efforts, the court approved Red Dog's request, and he was executed by lethal injection in 1993.
