Staten Island resident Jin Ok Choi said she rarely plays the lottery, so when she found out her July 3 Mega Millions Quick Pick ticket was the winner, she couldn't do anything but scream.

Choi, 54, was unveiled as the winner of the $85-million prize Thursday, along with other big lottery game winners, during a special presentation with New York State Lottery personalities Yolanda Vega and Ralph Buckley in Manhattan.

Choi, who will net a lump sum of about $40 million after taxes, said she is still in shock and doesn't know what she will do with the cash.

"I'm going to upgrade my life," she said.

Seven other million-dollar lottery winners joined Choi on Thursday. One of them was NYPD officer William Sena, 28, who won the top prize of $1 million on July 1 when he played the New York Poker scratch-off game.

The cop, who patrols Manhattan, will receive an annual net check totaling about $31,000 for the next 19 years.

Sena said he was going to use the winnings to buy a new house and invest in his daughter's college education, and said he won't be retiring from the force anytime soon.
