She did not speak to a crowd of reporters outside lottery headquarters, leaving quickly in a silver Ford Focus with her son, Scott Mackenzie, and family friends. She was accompanied by two unidentified attorneys, who left in a separate car.
MacKenzie bought the winning ticket at a Publix supermarket, a town of about 13,300 people located 30 miles northeast of Tampa. It is best known for bottled spring water that bears its name — and now one of the biggest lottery winners of all time.
In a statement read by lottery officials, Mackenzie said she purchased the ticket after another buyer "was kind enough to let me go ahead in line to purchase the winning ticket." Mackenzie played a quick-pick ticket, in which the numbers are generated randomly by lottery computers. She said she also purchased four other tickets for the same drawing.
"We are grateful with this blessing of winning the Florida Lottery Powerball jackpot. We appreciate the interest from the public, state of Florida and the lottery," the statement said. "We hope that everyone would give us the opportunity to maintain our privacy for our family's benefit."
The winner had 60 days from the May 18 drawing to claim the lump sum. Lottery spokesman David Bishop said Mackenzie, her lawyers and financial adviser were very prepared when they arrived, spending about two hours going through the necessary paperwork.
"They had clearly been preparing for this. They took all this time to get everything in order," Bishop said.
Minutes after the announcement, a dozen reporters in Zephyrhills were camped outside Mackenzie's modest grey duplex, which backs up to a dirt alley and is across from a cow pasture.
Neighbors were surprised and said Mackenzie never mentioned her big win.
"She didn't say anything about it. She's so quiet and secluded. She's usually in the house," said neighbor James Hill. "I'm very happy for her. It couldn't have happened to a nicer person. She was always pleasant and smiling."
Another neighbor, Don Cecil, joked "I hope she gets a better place to live."
Mackenzie's neighbors offered few details about her life, including how long she'd lived there and whether she was married. They said she mostly kept to herself, but they saw her take short walks along the street and exchanged pleasantries with her.
Mackenzie's house, which was situated among mostly mobile home and pre-fabricated houses, had a chain link fence with grey shutters, a tin sheet roof and an old TV antenna.
