(CHICAGO) -- A medical examiner says an autopsy on the exhumed body of a Chicago lottery winner who was poisoned with cyanide yielded no significant new clues about his death.
Cook County medical examiner Stephen Cina said Friday that no cyanide was found in Urooj (oo-ROOJ') Khan's body tissue but that was most likely because cyanide breaks down quickly. He says nothing significant was found in Khan's stomach.
Cina says Khan's July 20 death is still considered a homicide because tests on fluids drawn from his body before he was buried revealed he had been poisoned.
Authorities initially ruled that the Indian-born businessman died of natural causes, but his brother raised suspicions, leading to the further tests.
Authorities exhumed Khan's body in January to gather more evidence in case charges are filed.
