Niko Bellic's contact at United Liberty Paper orders him to locate Dimayev using the LCPD Database and kill him during the mission "Portrait of a Killer". He is located near a small garage in East Island City, Dukes surrounded by bodyguards, creating a shield that the player has to fight through before Dimayev can be reached. Niko kills Dimayev in the gunfight. Strangely, if the player kills all of his goons before reaching to him, he will drop his gun and the player will have a option of either killing or sparing him.
