Claim: John Factor (October 8, 1892-January 22, 1984) spent more than ten years in federal prison for stock fraud (United Kingdom) and mail fraud (U.S.).
Evidence: John Factor (October 8, 1892 – January 22, 1984), born Iakov Faktorowicz, was a Prohibition-era gangster and con artist affiliated with the Chicago Outfit. While in the United States, he was tried and sentenced in absentia in England to 24 years in prison. He fought extradition all the way to the U.S. Supreme Court, which heard oral argument on April 18, 1933. Factor's wife, Rella, then asked a U.S. federal district court to dismiss the extradition on the grounds that Factor had been held for longer than the two months permitted for extradition proceedings under U.S. law. The 7th Circuit Court of Appeals ordered Factor released and extradition proceedings quashed in In re Factor's Extradition, (7th Cir. 1934). Factor was convicted of mail fraud in 1942, and served six years of a 10 year sentence.
