Because there is no blood on the clothes and other relics at the scene, it can be preliminarily judged that the girl should have arrived in Hoh Xil for the purpose of suicide, and may have taken hypnotics and other drugs to make herself unconscious at the scene. Due to the cold and lack of oxygen in no man's land in Hoh Xil, the temperature at night is extremely low, which is the main cause of the death of the lost girl.
On July 5th, Huang, a senior student from Santai, Sichuan, who was studying in the School of Aeronautics and Astronautics, Nanjing University of Aeronautics and Astronautics, boarded the train to Golmud, Qinghai, and was suspected to be depressed due to graduation problems. On July 8, after the family could not contact him, they called the police in Jiangning, Nanjing through the school.
During the period of losing contact, the police in Jiangning and Golmud investigated her through the road she had traveled and searched along the way. On August 1 day, Huang's remains were found in no man's land on the south side of Qingshui River in Hoh Xil Nature Reserve, and a human bone was found at the scene, which was identified as Huang's remains.
