Halfway across the country, another big winner. We have new clues developing right now about the second powerball winner. This may be him, caught on surveillance, learning he's just won -- look at that. Come on. Abc's david kerley has the latest on this mystery man. David? Reporter: It's amazing, amy. How often do we get to see someone whose potentially won $200 million -- $275 million. But that's the way it happened here, at least that's the way it appeared right now. Can fairy tales come true? It seems like this anonymous man's happily ever after may have started at this station. Watch as cameras capture. He's dressed in a bright yellow outfit, surrounded by what looks to be a crew, all highway workers. And look here as he reaches deep into a pocket and fishes out what appear to be lottery tickets. Suddenly, he begins pumping his arms. I heard him say, he won. Reporter: Excitedly, he asked the cashier, check the ticket for him. Wanted everybody to look and check to see he wasn't seeing things. He wasn't seeing things. It was the right numbers. Reporter: He shows the ticket to another customer. Is this the right numbers? Yeah. That's the numbers. Man, you got them all. Reporter: Three people confirmed to our abc station, wjla, that the ticket he showed them was from arizona. And it did contain the winning numbers. An arizona ticket, with the winning numbers on it. Reporter: No one could tell us the man's name. But they claim he does live locally in maryland. It's amazing. I couldn't believe it. Reporter: Our last glimpse of this possible megamillion winner in waiting, driving off from the gas station after filling up his tank. If he is the big winner, that may be the last time he ever pumps his own gas. He forgot he needed to come in and get gas. Cameron is the guy that looked at the ticket. He saw all the numbers. They did not put it in the machine because it's from arizona. You can't read another state's ticket here in maryland. Now, if that is the winning ticket, the winner has 180 days to get back to arizona and claim that big prize.
