Exhumation of poisoned lottery winner under way

CHICAGO (AP) - Authorities have begun exhuming the body of a Chicago man who was poisoned with cyanide after winning the lottery.

Backhoes began digging at a Chicago cemetery Friday morning to exhume the body of Urooj Khan. The Cook County medical examiner plans to conduct another autopsy in an effort to figure out exactly how he died.

Khan died in July as he was about to collect $425,000 in lottery winnings. His death was initially ruled a result of natural causes, but a relative pressed for a deeper look.

Full toxicology results revealed in November that Khan was poisoned. His death was reclassified as a homicide.

Authorities hope a forensic autopsy will produce more evidence and tests on Khan's organs may determine whether the poison was swallowed, inhaled or injected.
