Just hours before announcing the winning numbers last year, lottery officials shared that the jackpot, originally estimated at $1.9 billion, had climbed to $2.04 billion, "making it the world's largest lottery prize." However, a week after the sole winner was publicly announced, a lawsuit was filed on Feb. 22. In the complaint, which PEOPLE has reviewed, Jose Rivera claimed to have purchased the ticket from Joe's Service Center in Altadena on Nov. 7, one day before the winning numbers were revealed. Rivera alleged in the complaint that his ticket was stolen before the drawing by an individual referred to as "Reggie" in the documents. The complaint lists California, the state's lottery commission, Castro, and "Reggie" — a fictitious name, per the document, which Rivera used as he does not know the individual's real name — as defendants. $560 Million Powerball Winner Fights to Stay Anonymous in New Hampshire Court However, the California Lottery maintains that the correct winner is Edwin Castro, whom they named as the sole recipient of the jackpot on Feb. 14. "When it comes to the vetting process for big winners, California Lottery has the utmost confidence in its process for doing so," Carolyn Becker, California Lottery spokesperson told PEOPLE in a statement. "California Lottery remains confident that Edwin Castro is the rightful winner of the $2.04 billion prize stemming from the Powerball drawing in November of 2022." In the complaint, Rivera alleged that he made "numerous" requests that Reggie return the ticket, but that the defendant refused. He went on to claim that Reggie tried to blackmail him into sharing the jackpot.

Rivera reached out to the California Lottery shortly after they named Castro as the winner and requested they investigate the claim, according to the court document. In a letter sent through his lawyers to lottery officials, which was included in the complaint, Rivera asked that they withhold making any payments until an investigation was made. Additionally, Rivera asked to view "any video that purports to depict Edwin Castro purchasing the winning ticket." In a statement to PEOPLE, the California Lottery said they aren't "authorized to investigate criminal activity among its players" and that "such allegations are subject to investigation only by local law enforcement." Rivera's attorneys didn't immediately respond to PEOPLE's request for comment.
