Oleg is the 49-year-old husband of the late Darya Chernova. He has balding black hair, stress marks on his forehead, and a lazy eye. He wears a brown coat with a fur collar. He also has a bandage wrapped around his right hand, multiple bandages across his face due to his wife forgetting to buy him razors (he had to use a knuckle knife), and a silver coin necklace around his neck. It is known that he eats beef stroganoff and that he turned to vodka after realizing that his wife was having an affair.
Events of Criminal Case
Oleg became a suspect after his and the victim's names were revealed on her gold bracelet. When informed of his wife's murder, he explained he hardly saw her as she was constantly working. Jack pointed out Oleg's current state due to drinking all that vodka, to which Oleg replied saying that was something his wife always complained about. Jack thought they would get nothing out of him in this state, so they left him until he became sober.
Oleg was spoken to again regarding his hair found on a knuckle knife in the subway station. He said he had that weapon because he believed his wife was cheating on him. Though he had no proof, he suspected it due to his wife neglecting her wifely duties. He said he was not planning to attack Darya with it; he was trying to catch her in the act, though he was intending to attack the man she was cheating on him with.
Oleg was found to be innocent after the team incarcerated Liam Hall for Darya's murder.
