Wanted woman poisons her lookalike with cheesecake to steal her identity

A con woman who tried murdering her lookalike with a poisoned piece of cheesecake almost got away with it. And if not for the sleuthing skills of the private investigator who tracked her down, she might have gotten away with something much worse, too.

"48 Hours" correspondent Peter Van Sant reports on the details in "The Case of the Poison Cheesecake" airing Saturday, June 3 at 10/9c on CBS and Paramount+.

In August 2016, Olga Tsvyk, a beauty stylist in Queens, New York, became gravely ill and lost consciousness after her client, Viktoria Nasyrova, came to her home and gave her a piece of poisoned cheesecake.
