Washington, U.S. -- Just call Melvyn Wilson "Mr. Lucky." The retired postal worker just won the lottery for the fourth time.
The local Lottery announced Tuesday that Wilson, 72, was the $500,000 winner of its Millionaire Mania scratch-off game. He had previously "hit the lottery three times in 10 months," reports The Washington Post: "$500,000 in November 2004, $25,000 in March 2005, and then $1 million from a scratch-off bought at a gas station in September 2005."
Wilson's latest $500,000 payout was second prize in the game. The $2 million top prize remains unclaimed.
Wilson claims that his luck comes from being in the right place at the right time.
Wilson isn't America's first four-time lottery winner. Stanford University professor Joan Ginther won almost $21 million in four lottery jackpots from 1993 to 2010.
