An 84-year-old woman claims $590.5 million Powerball prize.

The winner of a record $590.5 million Powerball jackpot has come forward, two weeks after winning the second-largest jackpot on record, according to the Florida Lottery.

Gloria Mackenzie, 84, was identified at a 3 p.m. press conference Wednesday.

She didn't attend the press conference, although under Florida law, her name was disclosed.

She bought the winning ticket at a Publix supermarket in Zephyrhills, a town of 13,000 about 30 miles northeast of Tampa.

The announcement end two weeks of speculation among the dreamers who snapped up millions of tickets in the hours ahead of the May 18 drawing.

The winner, who will be the largest sole lottery jackpot winner in history, had 60 days from the drawing date to claim a lump-sum payment. It's worth a pre-tax payout of about $370 million.

The jackpot eclipsed the $587.6 million Powerball jackpot split by Arizona and Missouri ticket holders last November and is second to the $656 million Mega Millions jackpot won in March 2012 by three ticket holders in Illinois, Kansas and Maryland.
