As the murders continued, a specialized task force was set up to investigate them, headed by the Kyiv Prosecutor's Office and the
Ministry of Internal Affairs. More than 10,000 people were investigated as potential suspects and several thousand cars were checked, but few clues came about as to the killer's identity. In addition, he remembered one part of the license plate, the letters "VI". Based on this information, the investigators started searching for any such cars across the country. Out of a total 7,043 cars, only 50 were registered in the Kyiv Oblast – Kuzmenko was never considered a suspect, as he drove the car by
power of attorney, and the real owner had an alibi for the day of Bondar's murder. After this, Paskal ordered that the investigators make a special questionnaire and distribute it across the Kyiv-Svyatoshynskyi and Vasylkiv Raions. In May of the same year, law enforcement officers came to the house of Yuriy Kuzmenko in Boiarka, where they talked with him and found out that he was driving such a car. During the conversation, Kuzmenko, at the insistence of a local district police officer, gave a
saliva sample for examination. His sample proved be a match, leading officers to consider detaining him for further questioning. However, Kuzmenko felt threatened after the visit, gathered his belongings and fled. While searching his house and garage, investigators found a bag with women's underwear of different sizes and styles, some of which had bloodstains. After he fled, Kuzmenko's wife gave law enforcement officers the address of his sister and brother's residences in Barakhty and Kyiv, where they soon organized ambushes. Initially, Kuzmenko hid at his sister's house, before traveling to Kyiv to visit his brother. ==Arrest, investigation and trial==
