A man who helped write the computer code behind several U.S. lotteries, including some of its biggest, pleaded guilty Thursday to masterminding a scheme through which he rigged the winning numbers for jackpots in several states and collected millions of dollars. Eddie Tipton, who worked for the Multi-State Lottery Association from 2003 until 2015 and was its computer information security director for his last two years there, appeared in a Des Moines courtroom, where he pleaded guilty to one count of ongoing criminal conduct and publicly acknowledged his lead role in the scheme. I wrote software that included code that allowed me to understand or technically predict winning numbers, and I gave those numbers to other individuals who then won the lottery and shared the winnings with me," Tipton said when asked by Judge Brad McCall to explain what he did. Tipton ... provided cohorts with the winning numbers for jackpots in Colorado in 2005, Wisconsin in December of 2007, Kansas in December of 2010 and Oklahoma in 2011. The group, which included Tipton's brother [and former Texas magistrate] Tommy Tipton ... also attempted to collect a $16.5 million Hot Lotto ticket in December 2010 in Iowa, but Iowa lottery officials refused to pay it because the men tried to cash it anonymously. Rob Sand, the assistant state attorney general who prosecuted the case, said after the hearing that it appears much of the stolen money is gone. Sand said the scheme resulted in payouts of $2.2 million.
