It seemed like a routine beauty appointment between friends, albeit an "emergency" one. Brooklyn woman Viktoria Nasyrova had a trip to Mexico booked, and she needed her Queens-based friend and beautician, Olga Tsvyk, to urgently fix her eyelashes before she went.
But it was Tsvyk's day off - surely Nasyrova could find someone else for the appointment? No, the desperate woman pleaded with the beautician, and eventually turned up at her house with three pieces of cheesecake as a "thank you" gesture for fitting her in.
The beautician enjoyed some of the cake - and 20 minutes later, an ill feeling came over her. She vomited, passed out, and Russian-born Nasyrova proceeded to ransack her room, stealing her passport, money and other belongings.

Tsvyk would soon find out that the cheesecake had been laced with Phenazepam, a powerful tranquilizer primarily found in Russia that 47-year-old Nasyrova had acquired in an attempt to kill her lookalike friend, and possibly steal her identity.
The police get involved
The frightening ordeal in August 2016 left Tsvyk hospitalised for three days, after her neighbour alerted an ambulance to the worrying scene at her Forest Hills Home. Tsvyk was passed out in bed, wearing only lingerie, and pills were strewn all across the room. For all intents and purposes, it looked like an attempted suicide scene.
