Citing privacy concerns, New Jersey lottery officials said McNeil asked that no news conference or check presentation be scheduled. A call to her home Saturday morning went unanswered.
McNeil's lawyer, Peter Pittenger, says she has taken a leave of absence from her job, which wasn't disclosed.
McNeil has been a Morris School District Board of Education member for four years. She bought her ticket for the March 13 drawing at a deli in Morris Plains, about 20 miles northwest of Newark.
