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 have a look, what Director Ma said was true, Ouyang Ping and Chen Jie saw this kind of city wall bricks in the courtyards of many people's homes, and some people's illegal buildings were built with city wall bricks, and some people even used city wall bricks to beat dog kennels. Ma Minglong also emphasized that even the homes of the residents of the "Thirteen Battalions", 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 nineties of the twentieth century, with the construction of modernization and urbanization, the city government put the repair and protection of the ancient city wall on the agenda), but the wall bricks that were added were in stark contrast to the old city wall (in the past, the city wall bricks were glued with lime and glutinous rice juice, and the later city wall bricks were glued with cement, and most of the wall bricks were missing arms and legs).

Since most people have this kind of city wall bricks, Ouyang Ping and Chen Jie'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 Jingnan, this kind of city wall bricks can be found everywhere).

After that, Chen Jie, Li Wenhua and Liu Wenbin continued to investigate for a while (re-combing all the clues), but they still had no clue.

After Ouyang Ping intervened in the case again, where should he start investigating? On the evening of October 28, the night after the murder case at No. 157 Impermanence Lane was closed, Ouyang Ping convened a meeting to analyze the case.

Director Feng also attended the case analysis meeting,"9. 27 "After the headless homicide case appeared in the news as a news, it became the focus of discussion among the citizens of Jingnan after tea and dinner, and the city government and the provincial department also attached great importance to this case. This invisibly added new pressure to Ouyang Ping and his comrades.

The case analysis will be conducted in Ouyang Ping's office, and Guo Lao was also invited by Director Feng.

Before the case analysis meeting began, Director Feng first stated: "The municipal government and the provincial public security department are very concerned about this case. The impact of this case is very bad, and we have been investigating for a long time, I hope that everyone will make persistent efforts and carry forward the spirit of facing difficulties, and the bureau will give full support to the comrades' investigation work, you see, Guo Lao is also here -- he is very concerned about this case, and the party and the people have entrusted us with such an important burden, and we have no reason not to pick it well; at Ouyang's request, we ask Guo Lao to go out of the mountain again, and hope that everyone will work together, pool their wisdom and efforts, 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. Ouyang 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, both sides of the Qinhuai River, densely populated, and mobile. So, the job is very difficult. But I believe that you will be able to win this case, and you have the ability. ”
