Despite having foresworn gambling after making the haj pilgrimage to Mecca in 2010, Khan bought a lottery ticket in June. He said winning the lottery meant everything to him and that he planned to use his winnings to pay off mortgages, expand his business and donate to St. Jude's Children's Research Hospital.
He was just days from receiving his winnings when he died before dawn on July 20.
The night before, Khan ate dinner with his wife, daughter and father-in-law at their house. Sometime that night, Khan awoke feeling ill. He died the next morning at a hospital.
Khan died without a will, opening the door to a court battle. The businessman's widow and siblings fought for months over his estate, including the lottery check.
