The patrol boat went all the way to the west.

The comrades spent a whole day traveling from Xihuamen Castle to the Sancha River (the confluence of the Qinnan River and the Yangtze River).

The content of this expedition is the soil quality along the Qinnan River.

This expedition was fruitful, and there are four places along the Qinhuai River that have the same soil quality as the clay in the brick openings of the city wall:

One place is the town of Flowers and the surrounding area.

The second place is Qingliang Mountain and the west side of Qingliang Mountain - the area from the west of Huju North Road to the Qinnan River.

The third place is the area directly opposite the crime scene and the area around the Ma Po Nunnery.

This Ma Po Po Nunnery was a small hill before the temple was built.

The fourth place is between Moling Road and Liuyedu.

The soil in these four places is exactly the same as the soil of the loess deep in the brick gaps of the city wall.

The person who came to this conclusion was Professor Ji.

As a result, Zhao Zimeng decided to investigate these four places. According to Xiao Lao's opinion, while investigating the four places, according to the predetermined plan, the boats on both sides of the river were investigated to find the traces of the deceased.

Three places have become the top priority, these three places are, Ma Po Po Nunnery, including the thirteen camps; the town of Flowers and the vicinity of Flowers Town; Moling Road and the area around Liuyedu.

To the west of Qingliang Mountain, to the south of Qinnan are hills and forests, and there are no residents except for the park management office. There are quite a few residents on the east, south and north sides of the park, but the soil has changed a lot, and Qingliang Mountain is enclosed in a wall, which is only a small part of the park.

Therefore, it is unlikely that the nearby residents will go to Qingliang Mountain to get soil and mud.

What's more, these residents did not have wall bricks in their homes. There is a long distance between Qingliang Mountain and the city wall, and most of the families who brought the city wall bricks home to build the wall lived near the ancient city wall.

There are a lot of buildings in the park, but most of them are ancient buildings, even if the house is repaired, the park as a public institution will not be poor enough to use city wall bricks as materials, and the unit will build a house, how many city wall bricks will it take!

When the common people take the bricks of the city wall home, they only make a small fuss, get a few, at most a dozen, mend the wall, or make the wall foundation or something.

In those years, although the society was relatively chaotic, the relevant management departments were not dry, and some people pried the bricks of the city wall on a large scale, and it was impossible for them to ignore them.

The reason why there are city wall bricks in the people's homes is not to get home overnight, today when they catch the opportunity, they will steal a piece, tomorrow when they encounter the opportunity, they will follow a piece, do not show the mountain, do not dew, and wait until the problem is serious, it is too late.

Therefore, Zhao Zimeng decided to start an investigation in three places first.

At noon on 29 July, Li Wenhua and Liu Wenbin had already copied the notice.

After discussing with Xiao Lao, Ling Hu Yunfei, and Xiang Daimo, Zhao Zimeng decided to divide the troops into four ways:

On the first road, Ma Jianping and Lu Qian, with the assistance of Zhang Huawei from the Moling Road Police Station, posted the notices to the three places mentioned above. Looking for a needle in a haystack, you need to fight a people's war, and a small pond to find a needle, you also need a people's war, and the reason why the restoration of Skynet is negligent but not leaky is inseparable from the extensive participation of the people, a pair of eyes can only see a little on the tip of the nose, and countless pairs of eyes can scan the corners and corners of life.

This is the experience that Zhao Zimeng summed up in his long-term criminal investigation practice, so he will not lose this housekeeping skill in the detection of the "6.27" headless case.

The second, third, and fourth roads went deep into Huashen Town, Moling Road and the 13th Camp, and convened the directors of the neighborhood committees to hold a meeting.

Third, the specific arrangements are as follows:

On the second road, Zhao Zimeng and Xiao Lao went to Huashen Town, assisted by Comrade Liu Daqiang from the Moling Road Police Station.

On the third road, Ling Hu Yunfei, Xiao Luhan and Ma Minglong investigated on Moling Road.

On the fourth road, Xiang Daimo and Lin Di went to the 13th battalion and were assisted by Comrade Bian Hope from the Moling Road Police Station.

Let's follow Zhao Zimeng, Xiao Lao, and Liu Daqiang to Huashen Town to have a look, and as for the other situations, we will listen to the report with Zhao Zimeng.

Before leaving, I would like to add two things:

The first thing: According to the instructions of Director Wang, the comrades moved into the Moling Road Police Station (on the morning of July 29, the comrades moved into the Molin Road Police Station).

The location of the Moling Road Police Station is at the west intersection of Moling Road, which is the closest to Liuyedu, standing in the corridor on the third floor of the police station, you can see the Liuyedu Eight Pillars Grass Pavilion, including the ferries coming and going on both sides of the river. You can also see the Ma Po Nunnery across the river and the Qingliang Mountain in the distance.

Ma Minglong arranged the comrades on the third floor, which is also an old-fashioned brick and wood building. Before the liberation, it was the town office of Moling Town, after the liberation, Moling Road was assigned to Baixia District, and the town office became a police station, with a duty room, a small conference room and a large conference room on the third floor.

Ma Minglong arranged Lin Di into the duty room, Xiao Lao, Ouyang Ping, and Ling Hu Yunfei arranged in the small conference room, and the others arranged in the large conference room. A few long tables are put together, bedding is spread, and a few quilts are placed, and it becomes a bed for sleeping.

The second thing:

Zhao Zimeng personally went to the city Qinnan River Governance Committee to go to a trip, the first phase of the Qinnan River dredging work is about to end, the next step is to segment the cofferdam, water absorption and dredging, because of the case, Ouyang Ping suggested, the cofferdam dredging work can start from the river between Moling Road and the thirteen camps?

Director Gao convened a meeting with other leaders and engineers, and decided to adopt Zhao Zimeng's suggestion to start the cofferdam dredging from the No. 5 section of the river (the section of Moling Road is marked as the No. 5 river section).

Ouyang Ping's purpose is very clear: the 6.27 case is a headless case, where is the head of the deceased? No one knows about this. If the deceased's head can be found, the case will have a substantial turnaround, the deceased's body is here, will the deceased's head be somewhere near the scene of the crime?

Therefore, Zhao Zimeng and Xiao Lao pinned their hopes on cofferdam dredging. Zhao Zimeng and Xiao Lao could not determine where the deceased's head was, and if Zhao Zimeng's suggestion did not conflict with the original treatment plan of the governance committee, the cofferdam dredging work should be carried out first in the No. 5 river section, which should be a good choice, so that the treatment plan of the Qinhuai River will not be disrupted, and it will cooperate well with the case. Isn't that the best of both worlds?

Zhao Zimeng and Xiao Lao followed Liu Daqiang and walked towards Liu Yedu. Walking on the embankment, in the distance, in the middle of a jungle, you can faintly see the outline of the city wall. The jungle is covered with an undulating hill, and between Moling Road and Liuyedu, it is a relatively open area, and the soil exposed under the grass under the trees is yellow. The soil inside the gap in the bricks of the city wall is this yellow-colored soil.

The murderer never dreamed that the bricks of the city wall he used to sink the corpse would reveal a very important piece of information to the police. This is probably called "one hundred secrets and one sparse", which is probably called "the agency is too smart, and the smart is mistaken by the smart"! With the addition of Xiao Lao, a new situation has emerged in the investigation of the case.

On the way to Huashen Town, the conversation between Xiao Lao and Zhao Zimeng has not left the case, Zhao Zimeng will not let go of this once-in-a-lifetime opportunity, and Ouyang Ping will not let go of any learning opportunity to work with Xiao Lao for a long time.

"Xiao Lao, ten miles of Qinnan River, in fact, Qinnan River is far more than ten miles, in the past two days, I have been thinking about a question."

"What's the problem?"

"The first scene must have something to do with this river, there is no doubt about it, I wonder, did the murderer sink the body on the spot, or in a different place?"

"Zimeng, you asked this question well!"

"Elder Xiao, I want to hear your thoughts."

"In the past two days, I've been thinking about this too, so we might as well be bold."

"Elder Xiao, you say."

"The first scene should not be too far from the site of the wreck."

"Why?"

"First, the yellow mud in the brick gap of the city wall should be an important support, whether it is Huashen Town, or the Thirteenth Camp and Liuyedu and Moling Road, these three are not far from the place where the corpse is displayed."

"And the second?"

Judging from the murderer's modus operandi, this can also be illustrated, the murderer has cut off the deceased's head, and the murderer has also taken off all the clothes on the deceased's body, so there is no need to go far. The murderer is afraid that people will recognize the dead, but who is afraid of recognizing the dead? It must have been a local person—and it can be inferred that the deceased must have been a familiar face in the local area, and there must have been more people who knew him—which also provides us with another important idea. ”

"Aren't there some distinguishing features on the deceased?"

In the eyes of the murderer, these characteristics are not important, and of course, it may be that the killer did not notice them - or that the incident happened suddenly, and the murderer ignored these details in a hurry and hurry. Third, if the distance of transferring the body is too long, there will be an emergency situation - after the murderer kills the deceased, he is in a hurry to dispose of the body, so, under normal circumstances, the murderer will not choose a place far away to sink the body, on the west side of the crime scene, there is a ferry, the ferry should be twenty-four hours a day - all-weather service, the density of population on both sides of the strait is relatively large, the ferry is the only passage for people on both sides of the strait to come and go, so, this ferry port should be relatively busy, you see-" Xiao Lao pointed to the ferry road," As soon as the ferry left the south bank, a lot of people gathered on the wharf, just now upstairs at the police station, I have already noticed that the ferry has to go back and forth every quarter of an hour, there is no chance to rest on the shore, at night, there will be a lot fewer people crossing the river, but there must be, the murderer will definitely avoid the ferry - the murderer's tool for sinking the body is inseparable from the boat. ”

"Old Xiao, I have a question, I don't know if to ask?" Lin Di listened to the conversation between Zhao Zimeng and Xiao Lao while thinking about the problem.

"Xiaolin, you say."

"The water level in the center of the Qinnan River is very deep, why did the murderer sink the body about 2.5 meters from the river bank?"
