LOS ANGELES — An unprecedented Powerball jackpot which rose to an astonishing US$1.6 billion -- or 58 billion baht on current exchange rates -- and became a national fascination will be split three ways. The winners' identities remain a mystery, but they bought their tickets in Florida, Tennessee and a Los Angeles suburb. They will each be entitled to 19.33 billion baht. The winners of the world-record jackpot overcame odds of one in 292.2 million to land on the numbers drawn on Wednesday night, 4-8-19-27-34 and Powerball 10. They can take the winnings in annual payments spread over decades or a smaller amount in a lump sum. The California ticket was sold at a convenience store in Chino Hills, lottery spokesman Alex Traverso told The Associated Press. The winning ticket in Tennessee was sold in Munford, north of Memphis, according to a news release from lottery officials in that state. Florida lottery officials said the winning ticket for that state was sold at a grocery store in Melbourne Beach, according to Bangkok Post.
