(CBS/AP) CHICAGO - An Illinois judge granted authorities permission Friday to exhume the body of Chicago lottery winner Urooj Khan.
Cook County Circuit Court Associate Judge Susan Coleman signed off on the request made from prosecutors and the medical examiner in their investigation into 46-year-old Khan's July 20 death.
Khan's death was initially ruled a result of natural causes, but further toxicology exams requested by a concerned relative led authorities to conclude in November that he was intentionally poisoned with cyanide.
Police have not announced any suspects, and the Khan's wife denied any involvement in his death.
Medical Examiner Stephen Cina said he hopes to gather additional evidence through more tests on the body that could be presented in court.
