The death of a Chicago lottery winner has led to a murder investigation after a post-mortem examination found he died of cyanide poisoning.
Urooj Khan, 46, died suddenly as he was about to collect almost $425,000 (£264,000), but his death was initially attributed to natural causes.
The local coroner reopened his case after a relative came forward.
Chicago police confirmed they were now investigating Khan’s death as a homicide.
« It’s pretty unusual, » Cook County Medical Examiner Stephen Cina said, commenting on the rarity of cyanide poisonings. « I’ve had one, maybe two cases out of 4,500 autopsies I’ve done. »
Mr Cina’s office found that Khan died shortly after ingesting a lethal dose of cyanide.
