Investigators uncovered that this enigmatic intern was Fyodor Shapoval, a repeat offender with a lengthy criminal history. He had been brought on board to eliminate witnesses in order to conceal the baby switch. During questioning, Shapoval disclosed the identity of his employer, a woman named Natalya Rudinskaya.

Love, Jealousy, and Baby Switch
Natalya Rudinskaya harbored a secret affection for Igor and concocted a scheme to end his marriage, believing it would lead to her own happiness.
To execute her plan, she bribed hospital personnel to facilitate a baby switch. By introducing a dark-skinned infant into Igor’s family, she aimed to drive a wedge between him and his wife. However, things quickly spiraled out of control, prompting Natalya to eliminate anyone who might reveal her deceit.
The Conclusion: Justice is Served
In the end, the court handed down its sentences: Rudinskaya was sentenced to seven years in prison, while Shapoval faced the maximum penalty. The Yuryevs were reunited with their biological child, and the dark-skinned baby was adopted by his biological father, the French chemist Fabien.
