So, Zhao Zimeng and his entourage took off their uniforms, shoes and socks, rolled up their sleeves and trouser legs, and with the help of five workers, eleven people, supported the corpse with their hands - together with the city wall bricks under the corpse, several residents found an old door panel and placed it under the corpse and the city wall bricks.

Everyone lifted the door panel to a vegetable patch on the shore (north bank) (there are many large and small vegetable patches under the embankment).

Zhao Zimeng also sent Linghu Yunfei and Xiang Daimo to conduct a serious examination of the mud under and around the corpse (Zhao Zimeng hoped to find some remnants of the scene), but found nothing, and it was impossible to gain anything, the deceased was naked when he was sunk to the bottom of the river, and he didn't even have a head, how could the murderer leave other objects (but Zhao Zimeng had to do this)?

Next, the dredging pump worked, and Liu Zhiqiang and Li Wenqing activated the dredging pump, which sucked water from the river and washed the mud on the corpse clean.

The dredging pump does come in handy, if you want to clean the sludge on the corpse, it must be 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 decompose, so the impact of the water did not destroy the swollen soft tissues of the corpse.

Ma Jianping and Lin Di took many photos, especially several important parts, such as the back of the deceased's right hand, the long scar above the left knee, and the hand and toenails (this is what Zhao Zimeng meant).

Below, let's take a look at Xiao Luhan's statement report on the surrounding environment of the crime scene (Zhao Zimeng felt that this was very important, so let Xiao Luhan be careful and complete it alone.) ）

This report proved to be very important in the whole process of solving the case.

In order to complete this report, Xiao Luhan conducted an on-the-spot investigation of the environment around the crime scene. The scope of the expedition extends to the West Gate Castle in the east; West to Liuyedu.

Liuyedu is a ferry crossing, one kilometer away from the scene of the crime.

south to the south bank of the Qinnan River, including a 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, Xiao Luhan also visited some people.

The location of the body is about 2.5 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 into a private vegetable garden by nearby residents.

According to nearby residents, the water of the Qinnan 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 as the vegetable field, in order to prevent flooding, the residents who serve the vegetable field will increase the vegetable field to a dozen centimeters above the highest water line.

Every winter, the water level is at its lowest, about 70 centimeters above the location of the dead body.

About a kilometer away from the site of the sink, there is a sluice, and under the sluice there is a pole marking the water level, and the staff of the sluice tell Xiao Luhan the water level line in different periods, which is completely consistent with the description of nearby residents in terms of the lowest point and the highest point.

Xiao Luhan pays special attention to the change of water level, and has his own considerations (the Qinnan River is the only river in western Beijing that is connected to the Yangtze River, and the flood season of the Yangtze River directly affects the water level of the Qinnan River).

The time of death of the deceased was about two months, and the time of the crime should be late April, so the time when the deceased was sunk was around April 27, which was precisely when the water level of the Qinhuai River began to rise. The current water level is about one meter, and in late April, the water level should be below one meter. This judgment was made on the basis of the water streak information provided by the sluice operator.

A few old people who often fish by the river said that in summer, they often fish in this area, and the fish nest is sprinkled just four or five meters away, the location is about the same as the location of the corpse, and the water depth is between one meter and eight to two meters.

The river at the scene of the crime is relatively wide, with nearby residents saying it is 150 meters wide. Xiao Luhan judged that the width of the river was indeed about 150 meters.

One of the anglers, Zhu Laosan, said he had broken a few lines and lost a few hooks at the location. At the edge of the vegetable patch, there is a road made of stones, which is obviously the place where the vegetable growers get water and water the vegetables.

Zhu Laosan likes to stand here to fish, in summer, the river bank is overgrown with weeds, especially on rainy days and after rain, the edge of the vegetable field is more muddy, and his feet are relatively clean when he stands on the stones, so he sprinkles fish nests here.

There is a three-story old-fashioned building on the opposite side of the river, and when Zhu Laosan sprinkles the fish nest, he will use the high roof ridge of this three-story old-fashioned building as a reference (because the Qinhuai River water is very fluid, there are no aquatic plants in the water, and there is no duckweed, so if you want to remember the location of the fish nest, you must find something as a reference).

In addition to this reason, this fish nest is relatively easy to catch fish (the fish are willing to run here, will it have something to do with the corpse). Xiao Luhan stood on a relatively large stone and looked at the three-story old-fashioned building on the other side of the river, and the location of the body was indeed on the line between the stone and the three-story old-fashioned building.

Zhu Laosan thought that the hook was hooked on a branch - or something, so when fishing later, try to keep a little distance from that point. After that, there was no more disconnection and loss of hooks.

Coincidentally, Zhao Zimeng and Linghu Yunfei really found a fishing hook on a few circles of wire (the wire that binds the chest and arms), and there was a large piece of fishing line on the hook, and the fishing line was wound around the wire.

The area on the north bank of the river is the so-called south of the old city, with one-color Ming and Qing dynasty buildings, blue brick walls, brown corridors, black tile roofs, warped roofs, lattice windows, dock walls, stone roads, shops with door panels, and stone steps outside the store.

Outside the embankment is a row of old-fashioned houses, and through the alley between the houses, is the street, which is called Moling Road, and is mostly lined with shops, usually two-story brick and wood buildings, and occasionally three-story brick and wood buildings. These brick and wood structures are generally occupied by people on the top and business on the bottom. There are also a few shops that run hotels, and the streets are not wide enough to accommodate only a horse-drawn carriage.

Ma Minglong introduced, from Xihuamen Castle to Liuyedu, there are more than 5,000 households, more than 100 shops, including three hotels, from the scene of the crime on the embankment, through an alley, diagonally opposite is a hotel, the name of the hotel is "Hongqi Hotel".

This inn is an old inn - and the largest inn in the vicinity, it was there during the Ming Dynasty, the original name was "Rugui Inn", in 1967, because of well-known reasons, "Rugui Inn" was changed to "Red Flag Inn".

The other three inns are called "Forward Hotel" and "Red Star Hotel".

Director Ma said that in three months, no missing person has been reported in his jurisdiction, so Xiao Luhan has paid enough attention to the three hotels.

The southern part of the old city has been a place where merchants have gathered since ancient times, and the population composition is quite complex, and the movement of people is relatively large (especially for businessmen). Therefore, it is very likely that the deceased was a mobile person (Xiao Luhan thought so).

The author's aforementioned dry rest house, on the west side of Moling Road - north of Liuyedu, was originally a government (in the Ming Dynasty it was the Cao Yun Division, and in the Qing Dynasty it was changed to a academy - the only academy in western Beijing) after the liberation of the Baixia District Public Security Bureau, in 1970 it became a dry rest house.

Director Ma said that there are more than 20 retired cadres living in the cadre rest center.

There is also a bathhouse on Moling Road, its name is Moling Bathhouse, the location is 500 meters away from Xihuamen Castle, this is an old bathhouse, most of the old people in the south of the old city come here to bathe.

Director Ma said that the water in the Moling Bathhouse is good - the so-called good water is that the temperature is controlled just right (because the master of the Moling Bathhouse boiler has been burning the boiler for decades.) The water temperature of several other bathhouses in the south of the old city is either too hot or too low, the water is too hot, people can't go down, it's too low, and it can't be soaked through).

The people who run the hall are all old people who have been working here for decades, they are all old runners, and they can serve customers comfortably, even those who rub their backs, pedicures, massages, knock on their backs, scrape and cupping are all old people.

Xiao Luhan, accompanied by Director Ma, investigated and visited the Moling Bathhouse, the deceased's fingernails and toenails - especially the toenails, before the trimming, the polishing is very smooth, and the nails can be taken care of to this extent, only a pedicure can do it, if you want to figure out the ins and outs of the deceased, the bathhouse is a place that cannot be ignored.

Under normal circumstances, people do not ask a pedicure to repair their fingernails, but this possibility cannot be completely ruled out, so if the deceased's fingernails and toenails are repaired at the same time, it is easier for the pedicure to notice the birthmark on the back of the deceased's right hand and the three brown hairs on the birthmark.

Since the deceased often had pedicures before his death, he would definitely rub his back, and there was a long scar above the deceased's left knee, and the bather should be able to notice this long scar when he was rubbing the bath.

The author adds by the way that Xiao Luhan visited all the back rubbers and pedicures in all the bathhouses in the south of the old city, but found nothing. The pedicure made it clear that they had been working as a pedicure for many years, and they had never seen anyone ask a pedicure to repair their fingernails, and the reason why people like to repair their toenails is that in addition to pursuing a relaxed enjoyment, it is mostly because people are not easy to take care of their toenails.

The scrubbers made it clear that if there were special signs on the customer's body, they would see it, because they called the back rub, which actually included every part of the body, including the back of the customer's hands, the instep of the foot and the heel.

Xiao Luhan also visited all the back rubbers and pedicure masters in all the bathhouses in Jingxi City, but still found nothing. Xiao Luhan spent too much time and energy on this line, but he didn't have a clue at all.

Liang Houzhong, the pedicure master of the Moling Bathhouse, once made a hypothesis - this hypothesis can only be imagined by a pedicure master.
