Blackjack Mulligan
In 1990, Blackjack Mulligan and his son Kendall Windham were arrested by the US Secret Service in a joint investigation with the Florida Department of Law Enforcement (FDLE) for counterfeiting. The authorities found close to $500,000 in phony $20 bills. As a result of a plea agreement, both father and son spent 24 months in a federal prison and were released in 1992.
