The mystery of the Mega Millions winners is still unsolved.

One week after a record-breaking $656 million jackpot, no one has come forth to claim the prize - unless you count the woman who says she won, but has not offered any proof.

Alleged lottery winner: Ticket hidden at McDonalds
Mega Millions $656M jackpot winners still unknown

The Maryland woman who claims to have a winning ticket worked at a Baltimore-area McDonald's. That ticket is reportedly hidden inside, but she isn't showing anyone, leaving some to wonder if it even exists.

The biggest lotto jackpot in U.S. history has gone from frenzy to mystery seven days after the winning numbers were announced.

Stephen Martino, director of the Maryland Lottery, told CBS News, "Since no one has claimed the ticket and since no one has even approached us, we would encourage people to look at their tickets very closely."

With three lucky tickets in three different states - each worth $218 million before taxes - only one person, at least publicly, is preparing to cash in.

Mirlande Wilson claims to be one of those big winners, purchasing her ticket at a Baltimore-area 7-Eleven store.

"I'm so shocked," Wilson has said. "I didn't even check the ticket. I didn't know what happened. I didn't call the media."

But her McDonald's co-workers aren't buying it, arguing she was part of their office lottery pool and should share the winnings. The single mother of 7, now with lawyers, says her ticket was bought separately. But even her attorney, Edward Smith, Jr. admits, "I have not seen the ticket, nor do I want to see the ticket."

Meanwhile, the McDonald's where Wilson's ticket may be stashed away has been under watch by two armed security guards.

The other winning tickets, sold in Kansas and Illinois, also remain unclaimed.

But the process of collecting a lottery prize isn't all that simple. Just ask Richard and Mary Morrison who won the lottery in 2010.

Mary Morrison told CBS News, "My biggest fear was coming out that we won the lottery, that someone would hurt my children or steal my children - even that someone would kill us."

The Long Island couple waited about two weeks to claim their jackpot worth $165 million.

"There was no inclination right from the beginning to cash this in," Richard Morrison said. "We knew that would have been a disaster."

Mary Morrison added, "My advice to anyone that wins a large sum of money is to get a team together that they trust, and always have your guard up because people do come into your life to take money from you."
