The Cook County Chief medical examiner says it will be a few weeks before tests could show how a Chicago man who was poisoned after winning the lottery died.
Stephen J. Cina said the body of Urooj Khan was in advanced state of decomposition.
Authorities exhumed Kahn’s body from his burial plot at Rosehill cemetery on the North Side Friday morning.
Khan died in July after winning $1 million.
An autopsy last summer ruled it was of natural causes, but toxicology tests performed at the request of a relative found cyanide in his system.
Investigators are trying to figure out if Khan inhaled or ingested the poison.
Cina said cyanide can evaporate over time so it’s possible cyanide that was in his system when he died won’t show up in the test results.
