For two years, she was determined not to let the killer of her little sister walk free. Unfortunately, it is likely that the influential relatives of the killer turned out to be stronger.

- After hitting Sapatinska, Rossoshanskyi didn't call the ambulance, but called to consult his father;
- The investigative team arrived at the spot a whole four hours later;
- She received hints that bribes were necessary for the court to choose jail as a provisional measure for Rossoshanskyi instead of house arrest;
- After the judge in the Vyshhorod court chose house arrest, Iryna managed to move the case to another court where Rossoshanskyi's uncle wasn't so influential, which was instrumental to establishing the 7-year verdict;
- The analyses to determine the presence of drugs in Rossoshanskyi's blood were falsified: the probe was switched during transportation, and the necessary medical assessment by a narcologist was done on another person, not Rossoshanskyi;
- It were actions of Nozdovska and lawyers which made the investigation pursue actions, from questioning witnesses to establishing facts, while the police sabotaged the investigation. Much of the proof of Rossoshanskyi's guilt was presented directly in court by Iryna Nozdrovska.
