The body of a Chicago man mysteriously poisoned with cyanide less than a month after winning $1 million in a lottery scratcher will be exhumed Friday as authorities try to determine exactly how he died, Breaking Celebrity News is reporting.

The Cook County medical examiner will exhume the body of Urooj Khan on Friday morning from a cemetery in Chicago.

As Breaking Celebrity News previously reported, Khan, 46, showed off his golden ticket in a ceremony at a Chicago 7-Eleven on June 26, 2012. A $425,000 check, Khan’s winnings after taxes, was issued July 19. The next day - on July 20 - after eating dinner at home, Khan began screaming in bed, and he was rushed to the hospital where he died.
