Because Chen Caihong's head is missing, it has become an important task to find the head, and the special case team analyzed that the perpetrator should not take his head to a far place, and may throw it somewhere outside the village, so according to the geographical environment, the village was divided into four pieces, and it was determined that the police were responsible for each piece of search, and at the same time mobilized the villagers to help search, because there was heavy snow everywhere, it was not found on the first day.

Although the whole pit was full of white and thick snow, but the snow did not fall again for five or six hours last night, the weather was clear after dawn, and the snow melted partially, and by the afternoon of the next day (that is, the afternoon of the third day after the incident) the snow had melted almost, and the task force again organized the police and the masses to search, and sure enough, a female villager found Chen Caihong's head in a rice field outside the village, and after careful search, no murder weapon or anything was found except for the head.

After the preliminary work, the special case team made a comprehensive analysis and believed that it was difficult to determine the motive of the criminals, and from the perspective of the horrific means of committing the crime, vendetta was the most likely, but Chen Caihong and his family did not have such a big feud with anyone at all, not even a small feud; If it is for sex, it can be found that Chen Caihong was not sexually assaulted, which led to the fact that the task force had no way to determine the exact motive, and finally decided to conduct a comprehensive investigation.

With regard to the perpetrators, the special case group held that the criminals were males, aged between 16 and 65, or people who had contacts and activities with the village, and therefore focused its investigation work on Fengkeng Village and those who had ties with Fengkeng Village, and looked for people among them who had the time and motive to commit the crime. It added a lot of difficulties to the screening work, and finally determined three key people: one was Chen Jiuwu, who pushed pai gow and lost money during the wake, because he pushed pai gow with a few people before dinner and lost money and wanted to gamble again, but he had no money on him and borrowed money from Chen Daping, and Chen Daping thought that gambling was not a good thing regardless of size, so he did not lend him and criticized him in public to persuade him not to gamble anymore, Chen Wujiu was very angry at that time, thinking that Chen Daping looked down on him, and gave him an ugly look in public, and left angrily after dinner and never showed up, when the police touched the platoon, he claimed to have gone home to sleep, but no one could prove that he really went home to sleep; The second person was a thirty-five-year-old bachelor in the village, who had spied on a woman bathing and pinching the breasts of a seventeen or eighteen-year-old girl, who had been beaten twice, because he had gone after dinner at night at the house where the old man had died, and claimed that he had gone home and slept because it was so cold because of the snow, and no one could prove it; The third is 24-year-old Song Xiaocai, because he was sentenced to theft in the village in the past and was released half a year ago, and during the examination, he claimed that he had eaten dinner at home that day and went hunting in the mountains, because the flashlight was broken later, and it was difficult to walk in heavy snow, so he stayed in the mountain watching shed on the mountain for a night, and returned home at dawn, and no one could prove it during this period.

The task force finally conducted an in-depth investigation around these three key people, because it could not be ruled out that they were examined separately, they all denied that they had killed someone, and the technicians compared their fingerprints with the mutilated fingerprints extracted from the empty wine bottle, although the fingerprints on the empty wine bottle were incomplete, but there were also some clear details, and these details and characteristics did not match these three people, plus further investigation and verification, the result was that they could not be identified as committing the crime due to insufficient evidence, and finally put them back.

After the three key people were temporarily excluded from committing crimes, the special case group carried out a new round of investigation, and expanded the scope of investigation, and identified Jiangkeng Village as a scope. According to the above situation, the task force was divided into four groups: one group was responsible for Fengkeng Village; The second group is responsible for Jiangkeng Village; The third group is responsible for outsiders who often come to Fengkeng Village or have lived in Fengkeng Village for a long time; The four groups are responsible for the basic situation and activities of the personnel of the Christian sites.

However, after more than three months of work, no new key suspects were found, and in the end, the special case team had to be dismantled and asked the police station and Zhu Dong and others to continue to pay attention to the case, but there were no new clues, and there was no progress in the case.

Although the case has not been solved, the special case group has done a great deal of work, and the various materials collected are more than a foot thick, which fully shows that the special case group attaches great importance to this case and the conscientious and responsible work attitude of all the combatants.

When Yang Qianfeng decided to re-investigate the case, he carefully read the more than a foot thick of the materials, and also learned about the direction of the investigation, the idea of investigation, the work arrangement, and the measures taken at that time, and thought that all the work was done very well, but he was worried that it was not completely done.

In order to have a comprehensive and objective understanding of the case, Yang Qianfeng first went to the scene of the case and clarified the location of the scene in the village and the real environment of the scene.

Fengkeng Village has a total population of 1,126 people, 295 households, there is a flat and wide open area between the two mountains in the pit, more than 70% of the people in the village live here, and nearly 30% of the families live on the side of the mountain on Zuoze, there is an ancient street in the middle of the village, the original village is very small, now all around are all the houses made by the villagers, and the whole flat area can be made of houses, which is many times larger than the original small village, There is a small river leading to the outside of the pit behind the old street, there is an ancient stone arch bridge on the river, Chen Daping's house is located in the village by the small river, more than 100 meters away from the stone arch bridge, there was no one on the other side of the river a long time ago, now there are more than 30 families who have made houses there, and Chen Daping's two sons live at the foot of the mountain over there.

Although Chen Daping had not completely come out of his grief, he was very happy to see that Yang Qianfeng really spoke and brought people in person according to his request.

What Yang Qianfeng didn't expect was that Chen Daping's wife Qian Cuicui lost her daughter, and she witnessed her daughter's tragic situation and collapsed her spirit, and she has not recovered yet.

After leaving Chen Daping's house, Yang Qianfeng divided the people into two groups and went to the village cadres to understand the situation, and he took Sun Wenqing to find the village secretary Li Kunhua, the security director Li Chunbo, and the village accountant Xiang Yang, and Zhu Dong and Zheng Gang to find the village head Qian Xiaohao and the women's director Jiang Lanmei.

Yang Qianfeng originally wanted to find them together to understand the situation, but he felt inappropriate, thinking that a lot of individual exchanges were easy to say, and they were clearer, through the conversation, Yang Qianfeng further understood the village customs and other conditions, and the village cadres agreed that the person who killed Chen Caihong would definitely not be from Fengkeng Village, the reason was that the people in their village were simple and honest, and there were very few petty thefts, but they would never do anything to kill people, not to mention that Chen Caihong was a little girl in the village who had no grudges against anyone. I wouldn't have killed her so ruthlessly. But when asked who was outside the pit who committed the crime, they couldn't provide any clues, but generally said that someone from outside the pit must have come in and did it. They can't be blamed for this, after all, they are not engaged in reconnaissance work, and there is some truth in what they say."

Then Yang Qianfeng asked some people in the village to visit, but none of them provided valuable clues.

Yang Qianfeng walked to the edge of the village and suddenly thought of Chen Nianbao, and decided to go to his house to have a look and learn about the situation of the believers in person.
