Yang Lijun's body was confirmed.

2013May 19, police in Xiangyin County found a female body in Xiangyin County, which is nearly 90 kilometers downstream of Changsha section of Xiangjiang River. The body has been badly decomposed, and it is impossible to distinguish its appearance. On the morning of May 20th, the police in Xiangyin County sent the corpse DNA samples to the Criminal Investigation Detachment of Yueyang Public Security Bureau for technical appraisal.

Xiangyin police extracted the DNA of the female corpse and sent it to Yueyang Public Security Bureau. Compared with the DNA of Yang Lijun's mother provided by Changsha Public Security Bureau, and the judicial expertise of the Criminal Investigation Corps of Hunan Provincial Public Security Bureau, it was confirmed that the woman had a biological mother-daughter relationship with Yang Lijun's mother, and it was confirmed that she was a "girl who fell into a well" in Changsha for about two months. Two months later, I finally received a letter from Yang Lijun. While expressing regret for the girl who died unfortunately, some netizens were puzzled. "After such a long time, from the information disclosed at present, why did you find a relatively complete will?" 2 1, the reporter interviewed an old forensic doctor in Changsha.

The forensic doctor said that the integrity of the remains has a lot to do with temperature and environment. The higher the temperature, the faster the decomposition of the remains. "On a hot day like 2 1, if you are in Xiangjiang River in Changsha, the body will start to rot for more than 20 hours." The forensic doctor said that the temperature in Changsha was not high in March, and the remains may initially sink to the bottom with the sediment, while the temperature of sewers and Xiangjiang channels is lower than the outside world, which is conducive to the preservation of the remains.

As for the specific time when the body floated, the forensic doctor said that it was "hard to say" and "only corruption can float up". When the remains decompose, a large amount of gas will be produced in the chest and abdominal cavity, which will produce a "macro view" and promote the remains to float from the bottom of the water.

Why was the body found in the river of Xiangyin section of Xiangjiang River? The forensic doctor said that the body may encounter some obstacles in the process of floating, but it will continue to drift downstream under the impact of the current.
