(Simpsonville, SC) -- It's been three weeks since someone won the one-point-five-billion-dollar Mega Millions jackpot, and no one has come forward to claim the prize yet.
The winning ticket was purchased at a KC Mart in Simpsonville. It's South Carolina's first Mega Millions jackpot win.
The winner only has 180 days to claim the prize. State law allows them to stay anonymous if they wish.
