Trucks, police cars, and a backhoe crowded the gravesite of 46-year-old Urooj Khan in Chicago today and two helicopters hovered overhead as preparations were made to exhume the man's body for autopsy.

After exhumation, Khan’s remains were ferried away from the north side cemetary in a black hearse escorted by police cars about 9am this morning.

A concerned relative contacted authorities after the man had died and the death was deemed to be from natural causes. After the family member made known their suspicions, tests were done and it was shown that the 46-year-old Chicago lottery winner had suffered from cyanide poisoning.

A second autopsy will be performed on the man’s remains. It is expected that the autopsy will convene immediately this afternoon after being delivered to the medical examiner’s office. The results of that autopsy should be out within two weeks. Stephen Cina, Chief Medical Examiner for Chicago said that the remains had to be dug up immediately, as the man’s body had not been embalmed. The autopsy will further confirm the results of the tests that showed cyanide poisoning as well as possibly show how the poison entered his body.

Cyanide poisoning is relatively rare as the poison is hard to obtain. A large amount of the substance would have to be inhaled or eaten to be lethal. Lesser amounts would only have caused weakness, confusion, headache and shortness of breath. There is a ban in place on buying retail products with the substance, but it is available in industrial products. Cyanide can also be found in cigarette smoke, almonds and kidney beans, but it exists in very small quantities in these items. It can also be found in Acetonitrile false fingernail remover, there it is found in larger quantities.

Khan won the lottery in June of 2012, by July, the man was dead. He died the day after he was issued a check for his winning ticket. Khan was presented with a giant check just after winning the lottery. Khan chose to take the lump some of $600,000, which worked out to approximately $425,000 after taxes. Khan had planned to put some of his winnings into his dry cleaning businesses of which he has several and pay off his mortgage. The ramaining money, Khan decided, would be donated to St Jude’s Children’s Hospital. Since Khan died before collecting his winnings, those winnings go to his estate according to the spokesman for the Illinois Lottery.

The night before his death, Khan, his wife, daughter and father-in-law had dinner on Chicago’s North side at West Rogers Park. By later that evening, Khan complained of feeling sick and collapsed from the chair he was sitting in.

Khan is survived by his wife Shabana Ansari and a 17-year-old daughter of a previous marriage. His wife and father-in-law have denied involvement in Khan’s death.

Khan’s widow and his siblings have been fighting over his estate since his death as Khan left no will.

Chicago police are being very tight-lipped about who they might suspect is behind the man’s death.
