The winner of a $1.35 billion Mega Millions jackpot — the fourth largest in U.S. history — has come forward to collect the prize, state officials said Wednesday. The Maine State Lottery said the winner chose to remain anonymous and collect the cash option through a limited liability company, LaKoma Island Investments LLC, instead of receiving the full amount in payments over time. The winning ticket was validated when a representative came to the lottery headquarters in Augusta on Friday, and the wire transfer of the money will take place before the end of the week, said Michael Boardman, deputy director of Maine Bureau of Alcoholic Beverages & Lottery Operation.
