Lotto officials wouldn't say what he did for a living.
A mechanic and his wife, Mark and Cindy Hill, of Dearborn, Mo., already have claimed their half of the multistate Powerball prize.
The jackpot was the second-largest in U.S. history and set off a nationwide buying frenzy. At one point, tickets were selling at nearly 130,000 a minute.
Before the Nov. 28 drawing, the jackpot had rolled over 16 consecutive times without any winners. In a Mega Millions drawing in March, three ticket buyers shared a $656 million jackpot, the largest lottery payout of all time.
Lottery officials said the Arizona couple moved from Pennsylvania a year ago. While in Pennsylvania, the couple regularly played the lottery but had done so only twice since moving to Arizona, Bach said.
After realizing he had won, the man and his wife spent the weekend "trying to recover from the shock," Bach said.
