Well, since the Lottery Commission has already recognized an "official" winner, Ms. Battles will have a very difficult time establishing any kind of claim to ownership.
I never said it would be easy. And she may turn out to be a fraud, but the idea of lost property is what I am addressing. The Commission may validate that someone holds the ticket, but that will not decide who gets the money in the end.
In the same drawing, a group of people I know here in Chicago had the winning number for $175,000. One of the people in the group has stolen the ticket. The rest have proved to police that they all owned the ticket and she was merely the one who went down to check the many tickets through the machine at the vendor. They have photo copies of all the tickets. She will never see a penny in all likelihood. I'll bet they cash in in the end.
