The second of three people who'll share a record $656 million Mega Millions jackpot has claimed a piece of the prize.

However, as with another winner who stepped forward in Kansas last week, the Maryland winner has chosen to remain anonymous, which the state allows, according to The Associated Press.

Nevertheless, Maryland Lottery officials will provide details about the winning ticket from the March 30 drawing at a news conference Tuesday at 8 a.m., according to a news release.

Today, they said the winner purchased the winning ticket at a 7-Eleven store in Milford Mill, Md., outside Baltimore, the AP reported.

A Maryland McDonald's employee, Mirlande Wilson, 37, has publicly claimed to be the winner from Maryland but last week told reporters she couldn't find her ticket. Lottery officials voiced skepticism about her claim.

A third winning ticket was sold in Illinois, but the winner has not yet stepped forward.

The total size of the largest-ever Mega Millions jackpot recently was adjusted upward  to $656 million after revised calculations on ticket sales in the 44 states that participate in the lottery, the AP reported.
