Mongolian investigators were the first to inspect the wreckage, arriving later the same day. They found an identity card belonging to Lin Liguo, confirming Lin Liguo's presence on the flight. Markings on the aircraft and surviving miscellaneous personal items confirmed the aircraft and passengers had originated from China, but the Mongolians were uncertain that any of the dead were either Lin Biao or Ye Qun. After inspecting the crash, the Mongolians buried the dead onsite.
