Ma Minglong led Ouyang Ping and his entourage to Liu Zhiqiang and the other five people, and after Ouyang Ping briefly asked the five workers about some information, he began to make preparations before the autopsy. Although the corpse was presented in front of everyone, the corpse was covered with mud, so it was imperative to wash the corpse with water, and the cleaning of the corpse must not be carried out in the cofferdam.

So, Ouyang Ping and his entourage took off their uniforms, shoes and socks, rolled up their sleeves and trouser legs, and with the help of five workers, thirteen people, supported the corpse with their hands - together with the city wall bricks under the corpse, several residents found an old door panel, placed it under the corpse and the city wall bricks, and then lifted the door panel to a vegetable field on the bank (north bank) (there are many large and small vegetable fields under the river embankment).

Ouyang Ping also sent Chen Jie and Yan Jianhua to conduct a serious examination of the mud under and around the corpse (Ouyang Ping hoped to find some remnants of the scene), but found nothing, and it was impossible to gain anything, the deceased was naked when he sank to the bottom of the river, and he didn't even have a head, how could the murderer leave other objects (but Ouyang Ping had to do this)?

Next, the dredging pump played a role, Liu Zhiqiang and Li Wenqing started the dredging pump, sucked water from the river, and washed the sludge on the corpse cleanly, the dredging pump did come in handy, and if you want to clean the sludge on the corpse, it is none other than the dredging pump, this thing, the amount of water is large, the pressure is also relatively large, and the silt on the corpse is washed by it, and there is no shadow. Thankfully, the corpse had just begun to decay, so the impact of the water did not destroy the swollen soft tissues on the corpse.

Many photographs were taken from Zuo to Dong, especially several important parts, such as the back of the deceased's right hand, the long scar above the left knee, and the nails on the hands and feet (this is what Ouyang Ping meant).

Next, let's take a look at Chen Jie's statement report on the surrounding environment of the crime scene (Ouyang Ping and Liu Dayu felt that this was important, so Chen Jie was left alone to complete it, and it turned out that this report played a very important role in the entire investigation process of the case. To complete the report, Chen Jie conducted an on-the-spot investigation of the environment around the crime scene. The scope of the investigation is east to Zhonghua Gate Castle; west to Liuyedu, which is a ferry port, one kilometer away from the scene of the crime; south to the south bank of the Qinhuai River, including a large residential area and several units on the south bank; To the north is the residential area on the bank of the river and the dry retreat we mentioned earlier. In addition to field trips, Chen Jie also interviewed some people):

The location of the body is about 1.5 meters from the river bank, and then up is a three-meter-long steep slope, which was supposed to be a gentle slope, and I don't know when it was reclaimed by nearby residents into a private vegetable garden.

According to the introduction of nearby residents, the water of the Qinhuai River presents different water levels in different seasons, in late July and early August every year, the water level is the highest, and the highest time should overflow the vegetable field, at least the same level as the vegetable field, in order to prevent flooding, the residents of the vegetable field will increase the vegetable field to ten centimeters above the highest water line; Every winter, the water level is at its lowest, about a meter above where the dead bodies are.

About a kilometer away from the site of the sink, there was a sluice, and under the sluice there was a pole marking the water level, and the staff of the sluice told Chen Jie the water level in different periods, which was completely consistent with the descriptions of nearby residents in terms of the lowest and highest points.
