Uhrooj Khan became ill shortly after they had dinner together.
Police say Khan was with family at his last meal, but he was the only one who ate it.
He was rushed to the hospital where he later died from what was later determined to be cyanide poisoning.
His death comes less than a month after khan won a million dollar lottery scratch-off last year.
Police have yet to name a suspect in the case.
Meanwhile, Khan's family is fighting over his lotto check.
