20-year-old winner of $451m US lottery jackpot wants to 'do good for humanity'

A 20-year-old man from Florida has claimed the $451m Mega Millions jackpot in the US, saying he wants to help his family and "do some good for humanity" with the money.

Shane Missler, of Port Richey, claimed the jackpot from the multistate game's January 5 draw but chose to receive his winnings in a one-time, lump-sum payment of $282m instead of more in annual instalments.
