CHICAGO — With no signs of trauma and nothing to raise suspicions, the sudden death of a Chicago man a day after he collected a large pile of lottery winnings was initially ruled a result of natural causes.
Nearly six months later, authorities have a mystery on their hands after medical examiners, responding to a relative's pleas, did an expanded screening and determined that Urooj Khan, 46, died shortly after ingesting a lethal dose of cyanide. The finding has triggered a homicide investigation, the Chicago Police Department said.
"It's pretty unusual," said Cook County Medical Examiner Stephen Cina, commenting on the rarity of cyanide poisonings. "I've had one, maybe two cases out of 4,500 autopsies I've done."
