The Massachusetts State Lottery had announced around 2:30 a.m. Thursday that a convenience store in Watertown, near Boston, had sold the winning ticket.
But shortly before 8 a.m., the lottery said it had made a mistake, and that the winning ticket was sold across the state at the Pride Station & Store in Chicopee, in Western Massachusetts.
The lottery did not say how the error was made .
It said the store in Watertown did sell a ticket that won a $1 million prize.
The lucky numbers for the second largest lottery prize in U.S. history were 6, 7, 16, 23 and 26, and the Powerball number was 4.
