(CNN) -- Concerned about her family's finances, a university student in Australia cashed some long-forgotten lottery tickets this week -- hoping the money would help her parents.
She discovered their worries are over.
The university student won $10 million (A$13 million) -- and helped solve a lottery mystery that has made headlines in Western Australia for 10 months.
"People had been wondering for months, who is this mystery winner? Do they know about this ticket?" said Jodi Eastman, spokeswoman for Lotterywest, the state lottery.
"We have a 12 month expiry on lottery tickets. And people thought it might end up expiring and go unclaimed."
Love it, sweet day she was having.
