General director and founder of Kamsky motor plant was killed this Sunday. The dead body of 32-year old Denis Kostin was found on the side of a road near "Promventilation" plant. Stranger attacked Kostin at 21:15 when he came out of plant and walked to automobile parking. Criminal thrust a knife at businessman`s stomach several times and escaped. General director died from obtained wounds. The Office of Public Prosecutor of Naberezhny Chelny instituted legal proceedings according to article 105 of Russian Criminal Code "Murder". Investigation has several versions of businessman`s murder including assassination because of commercial disputes. There is information that situation with criminal at KamAZ was unfortunate for a long time. Similar murder was committed at the beginning of 2004 in Yaroslavl. Then general director of company "Autodiesel-service" Evgeny Yurasov was killed. Crime was disclosed after 1.5 years - as investigation found out business partners of Urasov ordered the murder. Also investigation doesn`t exclude the variant that murder was committed by hooligans. This suggestion was made considering that businessman was attacked by knife - weapon uncharacteristic for professional killers. KamAZ refused to comment murder of Kostin. "He is not our worker, and we will not give any information", - announced press-service of company. They noted that Kamsky motor plant is not a branch of KamAZ but independent purveyor of motors.
