The mystery of an unclaimed lottery jackpot of $12.5 million appears to have been solved by a woman that had just come out of a coma. She insisted to her brother that he was the winner and died the next day.

A fortuitous combination of high-tech ingenuity and the intuition of a woman at death's door helped restore a stolen $12.5-million lottery ticket to its rightful owners.

CBC's the fifth estate has learned exclusive details about how the rightful owners of the ticket, allegedly stolen by an insider, were found seven years after the original 2003 purchase.

Seven friends who worked together at a construction company in southern Ontario finally received their money on Jan. 27, 2011, concluding a high-profile, years-long saga.
