A man who recently walked into an Upper Marlboro Exxon may be holding a Powerball ticket bought in Arizona worth close to $200 million, according to a report from WJLA.

Employees at the Marlboro Village Exxon told ABC7 reporter Jay Korff about the reaction of the man, captured on security camera video inside the store, who they say had a ticket with all of the winning numbers on it. 

Scott Peterson, press secretary for County Executive Rushern Baker, told Patch that Baker's official photographer was also in the store at the time the man learned he might be holding a winning powerball ticket and witnessed the scene unfold.

But so far, no one knows who the man is. NBC 4 reports that witnesses said the man told them he lives or lived in Chillum. 

Lottery officials in Missouri have verified that one lucky person has a winning ticket sold from that state. Arizona lottery officials have also said that a winning ticket was sold at a convenience store in Fountain Hills, AZ. If the mystery man from the Upper Marlboro Exxon does indeed possess a winning ticket, then he'll have to split the winnings with the Missouri Winner.
