The lottery could care less if she claims the money or not.
Since not all unclaimed prizes find their rightful owners, the question is: Where does that money go? Some states put the money into future lottery games, while others give the cash back to the community. In New York, for example, unclaimed prize money is returned to the prize pool. In Wisconsin, unclaimed prizes are used to help offset property taxes. Unclaimed prizes in Ohio are turned over to an education fund that supports K-12 students.

she shouldnt have played if she didnt want to be known. I understand her thinking, but why not just form a trust and have the trust claim it. many people do this
