Body of cyanide-poisoned Chicago lottery winner Urooj Khan exhumed for second autopsy

Chicago medical examiners are conducting a second autopsy on the body of a man who died from cyanide poisoning a day after collecting his lottery winnings. 

The body of Urooj Khan was exhumed on Friday and taken to the Cook County Medical Examiner's Office, the Associated Press reported.

Spokeswoman Mary Paleologos told the AP examiners would take "blood, tissue, bone, hair and nail samples," as well as test various organs to determine if the cyanide was "swallowed, inhaled or injected."

The BBC reported Khan would be buried again on Monday. The results of the autopsy would be available in two to three weeks. 

Khan died last July, a day after collecting the $425,000 lump sum option on a $1 million lottery ticket.

The businessman's death was initially ruled a result of natural causes, but a further examination at the behest of a concerned relative found he had ingested a lethal dose of cyanide.

Police are now investigating the 46-year-old's death as a homicide.
