CHICAGO - The widow of a Chicago lottery winner who died of cyanide poisoning says she has no idea who in their family asked that authorities take the deeper look into what originally was believed to be a death by natural causes.

Shabana Ansari spoke to The Associated Press on Tuesday, a day after news emerged that her husband's death in July was the result of cyanide poisoning.

Prosecutors, Chicago police and the Cook County Medical Examiner's Office are investigating 46-year-old Urooj (oo-ROOJ') Khan's death as a homicide. But they have not given any details, announced any suspects or ascribed any possible motive.

They've also not identified the relative who asked for a deeper look into Khan's death. Ansari said she didn't make the request and didn't know who did.
