The longest jail sentence ever:

The longest jail sentence passed was in the United States - 10,000 years for a triple murder. Dudley Wayne Kyzer was jailed for 10,000 years by a court in Tuscaloosa, Alabama, in 1981 for murdering his wife. He was then sentenced to two life terms for murdering his mother-in-law and a college student.

In 1994 Oklahoma rapist Darron Bennalford Anderson received a 2,200-year jail sentence. When he appealed and won a new trial, he was convicted again and resentenced to more than 90 additional centuries behind bars - including 4,000 years each for rape and sodomy, 1,750 years for kidnapping, 1,000 years for burglary and robbery, and 500 years for grand larceny.

In July 1997, the state Court of Criminal Appeals held that the grand larceny charge was double jeopardy on the robbery conviction and thus dismissed it. So the court cut Anderson's sentence by 500 years, speeding up his release date to the year 12,744!
