The owner of the Mega Millions lottery ticket worth $1.5 billion still hasn't come forward 22 days after winning the jackpot, and there is a deadline to claim the money.
The winner has 180 days — until April 21 — to collect the prize, according to Mega Millions' rules.
The winning numbers for the October 23 drawing were 5, 28, 62, 65, 70, and Mega Ball 5. The odds of winning the jackpot were about 1 in 303 million.
If the winner doesn't claim the money, it could go back into the game's prize pool or be given to South Carolina's development programs and plans funded by Mega Millions' profits.
Tony Cooper, the chief operating officer of the South Carolina Education Lottery, told ABC News that the winner should sign the back of the lottery ticket, store it in a safe place, and seek financial advice.
The lucky winner can choose to receive a lump sum of $878 million or $1.537 billion in installments over 30 years.
Profits from Mega Millions ticket sales go toward things like higher education, programs for senior citizens, and environmental protection efforts.
