The Kyrgyz National Security Service has narrowed the range of possible motives behind the June 10 murder of deputy Zhyrgalbek Surabaldiyev to two, service chief Tashtemir Aitbayev told a parliamentary session on Tuesday. \"The investigation centers on a criminal dispute theory as well as a theory linked to ownership disagreements over one of the republic\'s car markets [Surabaldiyev owned a car market],\" Aitbayev said. The investigation has established that the deputy was murdered by two young men of Asian and European appearance, who fled the scene of the crime in a white Mercedes car, which was found burnt outside Bishkek on June 11, he said. \"The investigation has established that the car was stolen from a Kazakh citizen. We have contacted our Kazakh colleagues and hope that investigators will be able to question the car\'s owner, who lives in Almaty, today,\" he said. More than 80 people have been questioned about Surabaldiyev\'s murder over the past two days, Aitbayev said. \"The parliamentarian\'s entourage has been examined, the number of suspects has been established and three of them have been detained and are being held at the National Security Service\'s pre-trial detention facility,\" he said. \"Unfortunately, many people from Surabaldiyev\'s entourage had problems with the law, and some of them have now been placed on the wanted list,\" Aitbayev said. \"The National Security Service\'s most efficient officers\" are engaged in the investigation, he said.
