Length of Sentence: 10,000 years
The longest prison sentence ever handed down in US history is attributed to Dudley Wayne Kyzer. In 1981, in Tuscaloosa, Alabama, he was found guilty for the murder of his wife. What lead the judge to sentence him to 10,000 years in prison? Apparently, the court decided that the brutality, with which he had slaughtered his spouse, more than merited such a long sentence.
