A winner has stepped forward to claim the lone winning ticket of Wednesday’s $758.7 million Powerball drawing.

A 53-year-old Massachusetts hospital worker, Mavis L. Wanczyk (pictured), was introduced Thursday afternoon at the Massachu-setts lottery headquarters, who described winning the lottery as “a pipe dream.”

Lottery officials say she chose to take a lump sum payment of $480 million, or $336 million after taxes.

A store in Chicopee, Massachusetts, sold the only ticket that won the jackpot, the largest grand prize won by a single lottery ticket in U.S. history.

However, 11 tickets that matched four of the five winning Powerball numbers — 6, 7, 16, 23, and 26 — plus the Powerball number of 4 were sold in Indiana, including one at a convenience store in Columbus.

The Hoosier Lottery reported that a ticket worth at least $50,000 was sold at the Circle K on 3461 U.S. 31 South, southeast of Columbus.

Two of the 11 Indiana tickets added the Power Play, making those winning tickets worth $200,000 each, the state lottery said.
