TALLAHASSEE, Fla. - After realizing he won $450 million in the Jan. 5 Mega Millions jackpot, the first thing Shane Missler did was to call his brother.

The next day, the 20-year-old from Port Richey told his father over coffee.

Missler claimed the lone winning ticket in the second largest jackpot won by a single ticket, the Florida Lottery announced Friday.
