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.
