Mavis Wanczyk, 53, lives in Chicopee, Mass., and as of Thursday morning, she is quitting her job at the local hospital.

“I called and told them I would not be back,” she said at Thursday’s press conference.

She found out she won last night as she left her job with a friend and was so unsure it was true that she passed the ticket along. Then it was confirmed.

"My numbers were kind of basically random, like maybe with our birthdays, one from here, one from there," she said at the press conference Thursday. "There's a thing between me and my mom and my stepfather and I have a friend, we all go out to dinner on a Friday night and we play Keno, and our number is four. I just happened to choose, and it worked to my advantage.”

The drawing was held in Florida Wednesday night and confusion reigned Thursday morning when the Massachusetts Lottery announced that the winning ticket had been sold at a market in Watertown just outside Boston.

Lottery officials sent news organizations to the wrong location. The owner gave interviews to all of the morning shows, but it later turned out to be the wrong store.

The ticket was actually sold across the state in Chicopee.

Wanczyk will take the lump sum, according to reports, walking away with $480,500,936 in a lump sum, which adds up to $336,350,655 after taxes.

For now, Wanczyk, who has two grown children, has a very simple strategy for her fabulous new wealth: “I just to go to my bed and hide.”
