And tonight, we have a winner coming out of the shadows. The second person holding the winning ticket to the $587 million powerball, about to step forward to claim his fortune in arizona. Abc's ron claiborne has the clues to his identity. Over half a billion dollar jackpot. Reporter: Mystery solved. Well, kind of. The winner has asked to remain anonymous. Reporter: But lottery officials did release a few tantalizing details. HE IS IN HIS 30s. He is married. And he lives in fountain hills. Reporter: He will share half of the $587 million top and has opted for the lump sum payment of $192 million. That's after paying upwards of $100 million in taxes. But much remains unknown. His job. Does he have children? And, of course, who is he? We know he isn't this guy, seen celebrating what he thought was the winning tick in maryland. The other winners, cindy and mark hill, ce forth publicly just two days after the drawing. We're still stunned by what happened. Reporter: The new winner may decide to reveal his identity eventually, which would allow him, if nothing else, to meet all those friends he never knew he had. Ron claiborne, abc news, new york.
