In the course of human history, civilization and ignorance have always gone hand in hand, and sometimes, the index of civilization can be said to be the peak, and sometimes, the degree of ignorance is staggering.

The tragic damage to the ancient city walls must have happened in that well-known era.

This situation was provided by Ma Minglong, in order to confirm his statement, he also led his comrades to the ancient city wall and some people to see, what Director Ma said is true, in the courtyard of many people's homes saw this kind of city wall bricks, some people built illegal buildings are built with city wall bricks, and some people even use city wall bricks to build kennels.

Ma Minglong also emphasized that even the homes of the residents of the "Thirteen Battalions" and Moling Road, which are separated by a river and thousands of meters away from the ancient city wall, have city wall bricks. As for the ancient city walls? Although it has been repaired (in the eighties of the twentieth century, with the construction of modernization and urbanization, the work of repairing and protecting the ancient city wall was put on the agenda of the local government), but the city wall bricks that were repaired were in stark contrast with the old city wall (in the past, the city wall bricks were glued with lime and glutinous rice juice, and the wall bricks that were supplemented were glued with cement, and most of the city wall bricks that were made up were missing arms and legs).

Since most people have this kind of city wall bricks, Zhao Zimeng's hope of finding clues to solve the case through the city wall bricks has been disappointed. The reason why the murderer dared to use city wall bricks as sunken corpses was also to make full use of the environment and conditions at the scene of the crime (in the city of western Beijing, this kind of city wall bricks can be found in many places).

The comrades thought of everything they should have thought of, but the investigation and visit never found anything, and after that, Zhao Zimeng sent Xiao Luhan, Lin Di and Lu Qian to continue the investigation for a period of time (re-combing all the clues), but still had no clue.

Where should the comrades start investigating? On the evening of 29 July, Zhao Zimeng convened a meeting to analyze the case.

After the "June 27" headless homicide case appeared in the news as news, it became the focus of discussion among the citizens of western Beijing after tea and dinner, and the city government and provincial departments also attached great importance to this case. This invisibly added new pressure to Zhao Zimeng and his comrades-in-arms.

The case analysis will be conducted in Zhao Zimeng's office, and Xiao Lao was also invited by Director Wang.

Before the case analysis meeting began, Director Wang first stated: "The Municipal ** and Provincial Public Security Departments are very concerned about this case, and this afternoon, when I had a meeting in the hall, Deputy Director Hou also specifically mentioned this case. The impact of this case is very bad, I hope everyone will make persistent efforts, carry forward the spirit of facing difficulties, the bureau will fully support the comrades' investigation work, you see, Xiao Lao is also here - he is very concerned about this case, the party and the people have handed over such an important burden to us, we have no reason not to pick it well, at the request of Zhao Zimeng, we ask Xiao Lao to go out of the mountain again, I hope everyone will work together, work together, overcome difficulties, and strive to win this case one day sooner. Of course, we don't have any burden, as long as we do our best, no matter whether we can win this case or not, the party and the people will affirm our work, I still have the old saying, this is what we do, as long as we work hard to get home, we will have a clear conscience. Zimeng told me about this case, I know some of the situation, the murderer of this case is very cruel and cunning, and the environment of the crime scene is so complicated, on both sides of the Qinnan River, the population is dense, and the mobility of people is very large. So, the job is very difficult. But I believe that you will be able to win this case, and you have the ability. ”

Before the case analysis meeting began, Xiao Lao also said a few words, although it was only a few words, but after listening to it, the comrades suddenly felt a lot more relaxed in their hearts.

"To be honest, I'm not worried about whether the comrades will be able to win this case - because you are a particularly capable team, the 'Condor Brigade', and this title is not blowing in the wind. I'm only worried about your body, I've had a lot of contact with you - in the last case, we just dealt with each other, as long as there is a case - no matter what kind of case, we have to face the difficulties, but we have to take it easy, but it's too hasty, the body is the capital, only with good rest and good health, we have enough energy to face all difficulties. Just now, Director Wang said something very good, 'As long as we work hard to get home, we will have a clear conscience.' 'I've been engaged in criminal investigation for many years, and I've had a lot of setbacks - there have been cases that I can't take, and we're not immortals who can pinch and calculate, so don't have any baggage, just do what you want. As for the case, as long as the season comes, it will definitely come to light, and time is the best weapon in our hands. It's the same as fishing, as long as there are fish under the water, there will be bubbles, and sometimes, the wind and waves will swallow all the blisters, so you need to be patient enough to wait until the wind and waves are calm, you will definitely see the blisters. ”

Xiao Lao's words were also said to Director Wang.

Director Wang also heard Guo Lao's voice: "Xiao Lao is right, you can't eat hot tofu in a hurry, everyone must pay attention to your body and move forward lightly, Zimeng, you must take care of your proportions - you have to be responsible for the health of your comrades!" ”

Next, everyone had an in-depth discussion and research on the case.

At Zhao Zimeng's request (Zhao Zimeng wanted Xiao Lao to talk about his views on the case from the perspective of forensic science), Guo Lao first talked about his own views (before that, Xiao Lao carefully studied all the materials): "Okay, let me say a few words first, judging from the autopsy results, the murderer's ability to counter-detect is very strong, he cut off the deceased's head and took off all the clothes on the deceased's body, from the perspective of forensic science alone, the murderer did not leave us any valuable clues, fortunately, the murderer left us - the murderer is too confident- Or in other words, he left us certain features of the deceased's body, and the murderer thought that as long as the deceased's head was cut off and the deceased's clothes were removed, even if the police found the body, they would not be able to investigate. Your initial criminal investigation thinking is correct, it is an important path to find the shadow of the deceased through the characteristics of the deceased, the birthmark on the back of the deceased's right hand and the very clean toe of the deceased,"

Xiao Lao held three photos in his hand, one of which was the back of the deceased's right hand, the other was the deceased's toenail, and the other was the long scar above the deceased's left knee. ”

Zhao Zimeng and Ling Hu Yunfei looked at each other for a moment, and Xiao Lao not only affirmed the work ahead of the comrades, but also pointed out some shortcomings.

Everyone is listening carefully to Xiao Lao's analysis, although the comrades have worked with Xiao Lao for many years, but such a serious analysis of the case, Xiao Lao is the first time, Xiao Lao is a person who is not good at talking, his ability is all reflected in the practice of criminal investigation, today, Xiao Lao has changed the style of the past, it can be seen how much he attaches importance to this case, Xiao Lao entered the role so quickly, it can be seen that he has his own ideas.

"Old Xiao, tell me what you think." Director Wang said, Director Wang's attention to the '6.27' headless case is not just a casual talk, inviting Xiao Lao to go out of the mountain is the first practical thing he did.

"Old Guo, say it quickly." Ma Jianping couldn't wait.

"Judging from the location of the murderer's body, as long as it is related to the Qinnan River, it should be included in our investigation."

According to Xiao Lao, the scope of the comrades' investigation and visit is indeed too small.

"There is no trace on the surface of the water, and the murderer is taking advantage of such a unique condition, this river is too long, as long as there is a boat, the river is at the foot." Xiao Lao said meaningfully.

"Yes, water can erase a lot of traces. This is where the murderer is clever and cunning. Director Wang also understood what Guo Lao said.

"The location of the murderer's body is on the north bank, which does not mean that the first scene was on Moling Road, and the murderer hid the body of the deceased under the river between Moling Road and the 13th Battalion, which does not mean that the first scene was on Moling Road and the 13th Battalion."

"Old Xiao, do you want to say that the first scene may be in the thirteenth battalion, and it is more likely to be on the south bank of the Qinnan River." Ma Jianping Road.

"Whether it's the south bank or the north bank, in short, whether it's the dead or the murderer, it's all related to this river. The murderer thought that as long as the body of the deceased was tied to the bricks of the city wall and sunk to the bottom of the river, everything would be fine, and the head of the deceased would be cut off, and the clothes on the deceased would be taken off to prevent accidents, the murderer was so confident, it made sense, Qinnan River, since the founding of the People's Republic of China, has never been completely governed, the murderer did not expect that the city ** would completely govern the Qinnan River, if the city ** did not govern the river, this case would become a permanent secret. ”

"Elder Xiao, what should we do next?" Linghu Yunfei asked.

"Zimeng, we can use the form of notices to post along the banks of the Qinnan River, and make public the height, age, and main characteristics of the deceased, including the relevant photos taken at the scene, Zimeng, take the mass line, isn't this your consistent practice?"

"Old Xiao, as soon as I heard you say this, my train of thought was opened." Zhao Zimeng said.

"Let's gather the household registration police and the directors of the neighborhood committees on both sides of the Qinnan River for a meeting, and with their participation, we won't have to worry about finding clues." Ma Minglong said (I forgot to explain earlier, Zhao Zimeng asked Ma Minglong to participate in the case analysis meeting.) ）

"Elder Xiao, should we focus our investigation on the foreign population?" Xiang Daimo said.

"Xiao Xiang is right, I was about to say this matter - you and I are here, it is very necessary to expand the scope - and it is also necessary, but don't ignore Moling Road and the Thirteen Battalions, as well as Huashen Town. It cannot be ruled out that the murderer used reverse thinking, and the so-called dark under the light is also suitable for our case. The killer may think that it is impossible for us to focus on the town of Flowers and the Thirteenth Battalion. ”
