Bizarre clues in botched cheesecake murder leads PI to wanted woman who poisoned lookalike Olga Tsvyk to steal identity

AN investigator has revealed the strange clues that helped him track down a woman who attempted to murder her lookalike with cheesecake.

Russian-born Viktoria Nasyrova was sentenced to 21 years in prison in April after being found guilty of attempted murder, attempted assault and unlawful imprisonment.

Nasyrova, 47, plotted against eyelash beautician Olga Tsvyk to poison her with phenazepam-infused cheesecake and assume her identity.

Tsvyk survived the attack that happened at her home in Queens. New York leaving her severely ill and unconscious.

One she returned home, she noticed that a number of her belongings including money and jewelry were missing and immediately turned police towards Nasyrova.

While the police searched for Nasyrova, so was a private investigator and former NYPD detective in connection to a case involving a murder in Russia.

A woman called Nadia Ford claimed Nasyrova had robbed and murdered her mother in Russia in 2014.

The private investigator was hired to help track down Nasyrova after he believed she fled Russia following the crime and needed to find a way to stay in America and stay away from the Russian authorities.

Herman Weisberg closely examined Nasyrova's Facebook profile in 2017 and found startling clues that allowed him to track her down.

He noticed in a selfie she took in a car, some distinctive white stitching on the headrest and in the reflection of her sunglasses, he saw the equally unique dashboard.

After looking into the windows of a number of cars in a parking lot, Weisberg discovered that the Russian woman was driving a Chrysler 300.

Next he had to try to identify her car in order to find the woman.

Returning to Facebook, he saw a number of likes and reviews for restaurants in an area of Brooklyn which is densly populated with Russians.

From this, he arranged a team to search the area for Chrysler 300s with the same interior that he had identified.

They found dozens and ran the plates until a Russian-sounding name appeared with an address.

The building linked to the address was that which can be seen in the reflection of Nasyrova's sunglasses in her selfie.

Weisberg and his surveillance team had found their location and just had to wait to find the suspect.

While there were a number of women who looked similar to Nasyrova, Weisberg employed some more top sleuthing to track her down.

"I was in narcotics where you're always constantly casing people," he explained to CBS.

"And when people run, they throw away a jacket or they turn their shirt inside out...bottom line is, nobody ever changes their shoes."

He added: "I got into a habit of when I size somebody up...I know what kinda shoes everyone's wearing."

The beige suede shows Nasyrova was seen wearing in surveillance footage linked to those seen in photographs on her social media profile.

On March 20, 2017, Weisberg alerted the police in Brooklyn and gave them her address and apartment number.

This saw Nasyrova arrested and what led to her 21-year sentence.

When searching her apartment, cops found an ID card belonging to Olga Tsvyk.

"(Nasyrova) laced a slice of cheesecake with a deadly drug so she could steal her unsuspecting victim's most valuable possession, her identity. Fortunately, her victim survived and the poison led right back to the culprit," Queens County District Attorney Melinda Katz said in a statement.

Once Nasyrova has served her time in the US, she may be deported to Russia to face murder charges there from the 2014 case.

The details of the case are all set to be aired in The Case of the Poison Cheesecake on Saturday, June 3 at 10/9c on CBS and Paramount+.
