A news conference to reveal who bought the ticket is planned for Friday morning at a high school in Dearborn, the small northwestern Missouri town where the ticket was purchased.

One of the jackpot’s two winning tickets was purchased at a gas station in Dearborn, about 30 miles north of Kansas City. The other was bought at a convenience store in suburban Phoenix.

The winners will split the record $588 million Powerball jackpot.

Missouri Lottery chief operations officer Gary Gonder says he can’t provide any details, including whether the ticket was bought by someone from Missouri.
