Liu Yuanxiang's home is very neat and clean, although it can't be compared with the houses in the city, but the furnishings in the house are neat and tidy, it can be seen that Liu Yuanxiang is a very virtuous woman.

Xu Lang and Ning Yanran came this time, not to visit the New Year, but to investigate the case, after Xu Lang and they entered Liu Yuanxiang's house, Xu Lang proposed to go to Li Chenghua's room to have a look, Liu Yuanxiang naturally had no opinion.

After Xu Lang entered the bedroom, he looked around in the room, the furnishings of the room were very simple, no different from ordinary people, beds, cabinets, and wardrobes should be there, Xu Lang looked around for a week, and saw a photo on the cabinet in the room, the photo was a group photo of a family of three, Liu Yuanxiang and Li Chenghua stood behind a girl, Liu Yuanxiang smiled very happily, full of kindness, although the girl was also thinking, however, Xu Lang felt that the girl seemed to have something on her mind, and smiled a little reluctantly, although Li Chenghua did not smile, But the expression on his face was very peaceful, and it could be seen that Li Chenghua was still very happy in his heart.

Xu Lang walked over, picked up the photo and looked at it, then turned his head and asked, "This girl in the middle is your daughter Li Nianzhi?" ”

Liu Yuanxiang's originally gloomy face, after seeing this photo, involuntarily eased a lot, she nodded slightly, and said, "Yes, it's just Nianzhi." ”

Xu Lang looked at the girl in the photo and remembered what Qin Liangping said on the phone, in the photo, Xu Lang couldn't see any disability in Li Nianzhi at all, the original three-petaled lips were long gone, and there was no trace of surgery on the lips, which made Xu Lang have to sigh, medicine is really developed now.

Xu Lang looked at the photo over and over again a few times, and then asked, "When was this taken?" ”

Liu Yuanxiang thought for a while, and then said: "It was probably filmed in the summer of the year before last, and I don't remember what day it was filmed." ”

Xu Lang nodded, did not continue to ask, but continued to check in the room.

When Ning Yanran looked at the photos in Xu Lang, she had already walked to the bedside table and opened the drawer of the bedside table, Ning Yanran found a wallet and a passbook in the drawer, Ning Yanran picked up the wallet, opened the wallet and took a look, and found that this was not Liu Yuanxiang's wallet, but a man's wallet, and it was Li Chenghua's wallet, in the wallet, there was not only Li Chenghua's ID card, but also two bank cards, but there was no cash in the wallet, not even a coin.

Ning Yanran stood up with her wallet and said to Liu Yuanxiang: "This is your husband's wallet?" ”

Liu Yuanxiang nodded.

Ning Yanran continued to ask, "Does your husband usually have the habit of putting money in his wallet?" ”

Liu Yuanxiang nodded again and said: "Yes, every time Chenghua goes out, he will put five hundred yuan and some change in his wallet, my family's character is like that, whoever is a little difficult, he will reach out to help." ”

Xu Lang heard Ning Yanran's question, and he noticed that something was wrong, he put down the photo in his hand, walked to Ning Yanran's side, took the wallet in Ning Yanran's hand and looked at it, and found that there was not a single coin in it, except for the ID card and bank card, the wallet was empty, Xu Lang frowned, if Li Chenghua was going out for something, then why didn't he bring his wallet, even if he didn't bring a wallet, at least he had to bring his ID card.

As we all know, ID card is the most important proof of a person, without ID card, you can't go anywhere, whether it's a car or a hotel, you need an ID card, of course, if Li Chenghua is just active in S City, then you don't need these, but Li Chenghua has been missing for more than three months, and now it's the Chinese New Year, if Li Chenghua is in S City, why doesn't he go home? Even if you don't go home if you have something, you should at least call home, but when Xu Lang and they entered Liu Yuanxiang's house, they found that Liu Yuanxiang not only had a landline at home, but also Liu Yuanxiang also had a mobile phone, even if Li Chenghua didn't call the landline at home, at least he should call Liu Yuanxiang's mobile phone, but according to Liu Yuanxiang, she didn't receive any calls from Li Chenghua, not even a single text message, which is very strange.

If Li Chenghua is not in S City, then where will he go? The most important thing is, how did Li Chenghua leave S City without bringing his ID card? Xu Lang couldn't figure it out.

Another point, that is, where is the cash of the few hundred yuan that Li Chenghua should have kept in his wallet now? So, Xu Lang asked, "After you go home, is your wallet here?" ”

Liu Yuanxiang nodded and said, "The wallet has always been here, and since Chenghua retired, he rarely carried his wallet with him. ”

"You took the cash from the wallet?" Xu Lang asked again.

Liu Yuanxiang shook his head and said: "No, I rarely touch Chenghua's wallet, and I never touch the money he puts in it." ”

Xu Lang and Ning Yanran glanced at each other when they heard this, and they both saw the doubts in each other's eyes, they chose to believe Liu Yuanxiang's statement, after all, Liu Yuanxiang and Li Chenghua are old husbands and wives, they have lived together for decades, and they know each other, Liu Yuanxiang doesn't need to lie, since Liu Yuanxiang didn't touch the money, where will the money in the wallet go?

If the money in the wallet was taken by Li Chenghua himself, then it means that he wants to go out, but since he is going out, why didn't he take his ID card? As an old man who has struggled in the public security system all his life, this common sense is still there, is it someone who has burglarized?

Thinking of this, Xu Lang asked, "When you went home, did you find that there were any traces of being turned over in the house, or traces of fighting?" ”

Liu Yuanxiang thought about it carefully, then shook his head and said: "No, when I came back, everything was normal at home, everything was placed at home according to the old way, and besides, except for the money in Chenghua's wallet, there was no shortage of valuable things at home, and the bank cards and passbooks in the wallet were not taken away, even the jewelry I put in the cabinet was still there." ”

Ning Yanran heard Liu Yuanxiang say this, squatted down and rummaged through the bedside table again, and sure enough, some jewelry was found in the bedside table, although these jewelry are not particularly valuable, but if you take them out and sell them, they can also be worth money, in addition, Ning Yanran looked through the passbook and found that there were more than 100,000 yuan in the passbook, and the last deposit was at the end of last year, and, judging from the records of deposits and withdrawals, in the last year or two, the passbook has no record of withdrawal except for depositing money in it. Ning Yanran told Xu Lang everything she saw.

Xu Lang pondered for a moment, and temporarily ruled out the possibility of burglary, first, except for the money in Li Chenghua's wallet, Li Chenghua's home did not lose anything, which does not conform to the common sense of burglary, as the saying goes, thieves do not go empty, if the thief comes to steal, there is no reason to only take cash and not those valuable jewelry, second, since there is no trace of being turned over in the room, and there is no sign of fighting, it means that no one else has come to the house except for Li Chenghua's family to live.

Next, Xu Lang and Ning Yanran looked around the room again, and found that in addition to the money in the wallet missing, Li Chenghua's mobile phone was also missing, and in addition, there was nothing missing at home, even the clothes that Li Chenghua usually weared, and even underwear, which did not look like a sign of going out.

Without finding any suspicious and useful clues at home, Xu Lang and Ning Yanran prepared to leave.

Just when Xu Lang and Ning Yanran walked out of Liu Yuanxiang's house, the pigs in the pigsty barked again, Xu Lang subconsciously looked over there, and then Xu Lang found that in the yard, there was a house close to the small western-style building, the door was locked, and it seemed to be a place to pile up sundries, so Xu Lang subconsciously asked: "What does that house do?" ”

Liu Yuanxiang, who sent Xu Lang and them out, said without thinking: "Firewood room." ”

"Firewood room?"

Before Xu Lang could say anything, Ning Yanran exclaimed.

Xu Lang turned his head and glanced at Ning Yanran fiercely, looking at Ning Yanran with the eyes of a turtle, Ning Yanran was a little inexplicable by Xu Lang, she really didn't know that there was a firewood house in the countryside now, she always thought that the firewood room was a place used by ancient people to pile up firewood.

Liu Yuanxiang saw Ning Yanran's surprised look, so he explained with a smile: "Yes, we are in the countryside here, and we still need firewood to cook rice, unlike in your city, where gas is used for cooking." ”

Ning Yanran, who was already a little embarrassed because she said the wrong thing, after hearing Liu Yuanxiang's explanation, her pretty face suddenly turned red, and she whispered: "Aunt Liu, I'm sorry, I really didn't know that there was still a firewood room, besides, don't get me wrong, I don't mean anything else, I just feel curious." ”

Liu Yuanxiang shook his head and said he didn't mind.

Xu Lang, who originally just asked casually, had no intention of going to see it after learning that it was just a firewood room, so he left Liu Yuanxiang's house with Ning Yanran.

When Xu Lang and the others were leaving, Liu Yuanxiang took Ning Yanran's hand, and said with red eyes: "Two police comrades, you have worked hard, if you find Chenghua, you must tell me, I thank you in advance here." ”

Ning Yanran looked at this woman whose face was still wrinkled and her hair was beginning to turn gray, she couldn't help but have a sour nose, nodded vigorously, and said, "Aunt Liu, don't worry, as long as we find Uncle Li, we will notify you as soon as possible." ”

After speaking, Ning Yanran and Xu Lang got into the car and left together, and after they left, the pigs in the pigsty barked again.

————

In fact, strictly speaking, in the absence of a body, Li Chenghua's disappearance is just an ordinary civil case and is not under the management of the Second Criminal Investigation Team, however, Li Chenghua's identity is somewhat different, and his superiors attach great importance to Li Chenghua's disappearance.

If you want to investigate where Li Chenghua is now, you must first figure out one question, that is, whether Li Chenghua is missing or killed.

If it is missing, then where will he go? Where can you go? After all, before he disappeared, he didn't bring his ID card or extra money, which is a big problem, and Li Chenghua disappeared not for a day or two, but for more than three months. Is it just a few hundred dollars? If it was the last century, a few hundred dollars would indeed be a lot, but in the current rapid economic development, a few hundred dollars is not enough to do anything.

If it was killed, then where is Li Chenghua's body? Why were no bodies found?

These two different possibilities lead to different directions of investigation.

Since it is still uncertain whether Li Chenghua is missing or killed, let's start with Li Chenghua's interpersonal relationships.

After all, everyone's interpersonal relationships and acquaintances are different, and it is very difficult to investigate one thing, but even if it is difficult, complicated, and cumbersome, the investigation should continue to investigate.

However, the results of the investigation made everyone very disappointed, because no one knew where Li Chenghua went, and even they didn't know when Li Chenghua disappeared, which made Xu Lang's investigation deadlocked.

Four days later, that is, on the tenth day of the first lunar month, on the 23rd day of the second month of the solar calendar, Ning Yanran received a call from Liu Yuanxiang.

On the phone, Liu Yuanxiang sobbed silently and told Ning Yanran a shocking news that she had found Li Chenghua's body, and the body was now at their house.

After Ning Yanran learned the news, she immediately called Xu Lang, and then drove to Liu Yuanxiang's house with the second criminal investigation team and forensic Ye Xuefei.

After Xu Lang and the others arrived at the scene, they found that Liu Yuanxiang's door was not locked, they pushed the door and entered, and found Liu Yuanxiang slumped on the ground with a dirt, stains everywhere on Liu Yuanxiang's body, and a pungent odor, which was the smell of feces.

Everyone subconsciously raised their hands to cover their noses when they smelled this smell at the beginning, but Ning Yanran took two steps back, Xu Lang didn't care about this, walked straight to Liu Yuanxiang's side, squatted down, looked at Liu Yuanxiang's eyes and asked, "Aunt Liu, where is Uncle Li's body?" ”

After Liu Yuanxiang saw Xu Lang, she didn't come back to her senses for a long time, her smoke ring was red and swollen, after Xu Lang asked a few times, she stretched out her hand and pointed to the direction of the pigsty, Xu Lang looked in the direction that Liu Yuanxiang pointed over, and found that there was a mound of soil for piling up pig manure on the side of the pigsty, and the mound had been partially opened, Xu Lang vaguely saw a human leg, Xu Lang stood up, threw a look at Ning Yanran, and then walked straight towards the pigsty.

After Xu Lang walked in, ignoring the pungent stench that filled his nose, he saw that in a pile of pig dung, there was a person's corpse, the corpse was swollen and began to decay, and there was a giant imagination.

Although the body was swollen because of **, according to the corpse's clothes and puffy face, Xu Lang recognized the identity of the deceased, who was Li Chenghua, who had been missing for three months.

A few days ago, they were still looking around for Li Chenghua's whereabouts, but they didn't expect that only a few days later, his body was found in Li Chenghua's home, which caught Xu Lang and them off guard for a while, however, since the matter has happened, then now, the only thing that can be done is to find out the murderer of Li Chenghua, but, before finding the murderer, now Xu Lang What they have to do is to clean up the body from the feces, so, under the personal leadership of Xu Lang, Zhao Hua and they each have a shovel, Clean-up began in the stinking feces.

Because of the phenomenon of giant view of the corpse, Xu Lang was very careful and slow when they cleaned up, firstly, because they were worried that the shovel would scratch the corpse and cause secondary damage to the corpse, and secondly, because once the corpse appeared in the phenomenon of giant view, especially in the fecal heap full of methane, once it was not properly disposed of, it was easy to have an accident, which would bring great trouble to the autopsy after the forensic doctor, so Xu Lang and they cleaned up the feces around the corpse with a shovel. I began to clean the feces around the back of the corpse with my bare hands, and the feeling can be imagined, how disgusting and nauseous it was.

After two or three hours of intense work, Li Chenghua's body was finally cleaned up, and the surrounding feces were also cleaned aside, Xu Lang and several of them were also the same as Liu Yuanxiang, they were all stained with feces, exuding a strong smell, Xu Lang himself didn't dare to breathe hard, he was afraid that if he couldn't bear it, the scene would be spit out, the shame was small, in case the scene was destroyed, it would be a big problem.

After Ye Xuefei cleaned up in Xu Lang, she took a toolbox to conduct a preliminary autopsy on the body at the scene, and during the second period, Ning Yanran began to ask Liu Yuanxiang about what happened.

It turned out that Liu Yuanxiang was relieved a lot after Xu Lang took over the case, her daughter Li Nianzhi did not go home, Li Chenghua was not at home, she was the only one left, she felt that there was no New Year's flavor this year, and there was still a pig at home, this pig had to bark a few times from time to time since she came back, which made Liu Yuanxiang very helpless and confused, at first, she thought that the pig was hungry, so she barked, but after she fed the pig food, she found that the pig was still barking, and had been walking around in the pigsty, but she was unwilling to lie down, This made Liu Yuanxiang feel a little strange, and later, when she thought about it, she thought that it might be because of the accumulation of pig manure, and the pig had no place to sleep, so she called, so she picked up a shovel to shovel pig manure, in the past, Li Chenghua did these things with her, and now Li Chenghua is not at home, she can only do it alone.

When she started shoveling, she didn't feel that there was anything wrong, but when she shoveled, she found that something was wrong, because she shoveled out a human leg wearing pants in pig dung, Liu Yuanxiang was startled at first, and then, she felt wrong, because she found that the pants on people's legs were very similar to the pants that her man usually wears, which made her start to suspect that the deceased was her husband Li Chenghua, so she mustered up the courage to shovel the pig manure on the face of the corpse, and after carefully shoveling, she found out, The deceased was her own man Li Chenghua, which made Liu Yuanxiang almost faint on the spot, she was sitting on the ground full of pig dung, after some fear, she remembered to call Ning Yanran, and then Ning Yanran and they rushed to the scene.

After Xu Lang and the others cleaned up the scene, they went to the pool and began to wash up, after all, each of them was covered with feces, not to mention how disgusting the feeling was, but what made them feel disgusting and angry the most was not the feces on their bodies, nor the smell of the scene, but the place where Li Chenghua's body was found.

If Li Chenghua's body is found anywhere, they can still reluctantly accept it, but if Li Chenghua's body is found in Li Chenghua's own pigsty, it will be different, everyone who is a policeman, when they choose the police profession, they are ready to sacrifice at any time, and they are ready to die generously at any time, but no one wants to die, no one must die, everyone's life is fate, not to mention the people's police, and he is also an old policeman who has retired with honor.

Originally, they still had a lot of complaints in their hearts about Lu Ye calling them back in advance to find a case of missing persons, but after seeing Li Chenghua's swollen corpse because of **, everyone felt very angry, and the unhappiness in their hearts had long since disappeared, and some only had anger and hated the cruelty of the murderer.

After a preliminary autopsy, Ye Xuefei came to a preliminary conclusion that the deceased was beaten on the head with a blunt object, resulting in cranial hemorrhage and death, because Ye Xuefei found several traces of being beaten with a blunt object on Li Chenghua's head, and the back of the deceased's head was dented, and there were blood stains, as for the time of the deceased's death, because the deceased was buried in a dung heap, because of factors such as climate and bacterial growth, Ye Xuefei could not give an exact time for the time being, and could only roughly speculate, The deceased had been dead for about three to four months, which was very close to the time when Liu Yuanxiang said that Li Chenghua disappeared.

After Ye Xuefei did the preliminary autopsy, Zhao Hua and the others put Li Chenghua's body into a body bag and carried it out of Liu Yuanxiang's house, and Liu Yuanxiang was also persuaded by Ning Yanran to change into clean clothes and was also taken back to the second criminal investigation team.

With the discovery of Li Chenghua's body, not only Lu Ye was very angry, but also the comrades of Fengyun Prison and the comrades of the anti-drug brigade were angry.

A policeman who has retired with honor, a policeman who was once an anti-drug hero, and a prison guard who has reformed countless prisoners, he was brutally killed, and buried in a pig manure heap in a frenzy, this practice undoubtedly does not reflect the murderer's perversion and rampantness, this is the rhythm of the naked declaration of war to the public security system, and the leaders of the provincial public security department are also very angry and attach importance to it after learning the news, they ordered Lu Ye to solve the case within the specified time, and must find out the real culprit and give severe punishment.

After receiving this notice, Lu Ye directly called Xu Lang, Ning Yanran and Wu Yong to the office, and asked the three of them to make a military order to solve the case within fifteen days, if the case cannot be solved within a time limit, then, everyone present, one counts as one, all take off their clothes and get out, go home to farm, and at the same time, the 223 serious crime team was established on the same day.

In addition, Lu Ye asked all police forces in S City to cooperate with the investigation of the 223 Serious Crime Team, and Fengyun Prison and the Anti-Narcotics Brigade also actively cooperated with the investigation, so before the fifteenth day of the first lunar month, the first battle of the new year began.

After the establishment of the 223 Serious Crime Team, the Second Criminal Investigation Team and the First Criminal Investigation Team cooperated again, and Lu Ye personally took command to participate in the investigation of the case, and the scene was divided into three teams.

The autopsy team is in charge of Ye Xuefei, and other forensic doctors in S City cooperate with the autopsy work.

The on-site investigation team was jointly responsible for Wu Yong and Xu Lang, and other personnel cooperated with the action.

Ning Yanran was in charge of the investigation team, and the prison and the anti-narcotics brigade worked together to coordinate the operation.

Because Li Chenghua's work is special, he was a police officer in the anti-drug brigade before, and he faced extremely vicious drug traffickers, how vicious this group of people is, needless to say, everyone in the serious crime team is psychologically very clear, compared to the anti-drug brigade, there will be sacrifices every year, and prison guards are a profession that gets along with criminals day and night, and they have to manage so many prisoners every day, and it is inevitable that they will have conflicts with some prisoners, so that they will be held by prisoners in their hearts, so as to carry out retaliatory actions, these are all possible, so, Ning Yanran's work is the top priority, because what she wants to investigate is not a single criminal, but countless criminals, among which are drug dealers.

After the establishment of the 223 Serious Crime Team, Ning Yanran joined the anti-narcotics brigade and Fengyun Prison to conduct a detailed investigation of all the prisoners who had contact with Li Chenghua, whether it was a prisoner serving a sentence in prison or a person who had been released from prison, it was necessary to conduct an investigation, and the prisoners who were serving a sentence in prison were very convenient to investigate, and Qin Liangping was fully responsible for this aspect, after all, Fengyun Prison was under his jurisdiction, and the investigation of drug dealers was fully handed over to the anti-drug brigade to be responsible. After all, they knew far more about drug dealers than Ning Yanran and them.

Ning Yanran is personally responsible for the people who have been released from prison, especially the prisoners who have just been released before Li Chenghua's death, Lu Ye's requirements for Ning Yanran are very strict, that is, it is necessary to find out that every prisoner who has been in contact with Li Chenghua, where they are now and what they are doing during the period before and after Li Chenghua's death, and once they find something suspicious, they will immediately bring them back to the Public Security Bureau for questioning.

Wu Yong and Xu Lang personally led people to investigate the scene and find the first crime scene of Li Chenghua's murder, after all, the detection of countless murder cases is inseparable from the first scene, because only the first crime scene can find more evidence and clues.

And Ye Xuefei and others, after Li Chenghua's body was sent to the autopsy room, the forensic doctor headed by Ye Xuefei conducted a careful autopsy and analysis of Li Chenghua's body, striving to bring more favorable help and proof to Xu Lang's detection.

The first to find clues was Wu Yong and Xu Lang's on-site investigation team, they conducted a detailed investigation of Li Chenghua's home, Li Chenghua's home had already conducted a preliminary investigation when Xu Lang and Ning Yanran went to the last time, but this time, under the leadership of Xu Lang and Wu Yong, a detailed investigation of the scene was carried out, and every corner and every inch of land was not spared.

At the beginning, Xu Lang did not find anything suspicious, except for the pigsty, no other traces were found at the scene, and finally, when Xu Lang and they got the key to the firewood room from Liu Yuanxiang, they found the first crime scene, in the firewood room, they found a large number of bloodstains, these bloodstains through technical analysis, found that they were Li Chenghua's bloodstains, and at the scene, they found a firewood knife for chopping wood, and bloodstains were also found on the firewood knife, and the first crime scene was found, which was in Li Chenghua's home.

However, what puzzled Xu Lang and the others was that there was not a single fingerprint found on the firewood knife, not only Li Chenghua's fingerprints, but also Liu Yuanxiang's fingerprints, and Li Nianzhi's fingerprints.

After Xu Lang and they found the scene of the first crime, Ye Xuefei also had the results, according to their dissection of the corpse and the technical comparison of the firewood knife they found, it was found that Li Chenghua was indeed beaten on the head with the back of the firewood knife, causing cranial hemorrhage to death, and Li Chenghua's death time was three and a half months ago, that is, around December 2009, as for the more specific time, with the current technical means, there is no way to get further clues.

In addition, when Ye Xuefei performed an autopsy, she found that the murderer should be a woman, or a man with little strength.

The reason why Ye Xuefei has this judgment is that the deceased's wounds were caused by multiple beatings, not all at once, and the strength of each wound is not very heavy, not like the strength of an adult man, and secondly, the deceased was kicked in the lower body before his death, and he was kicked three times.

Based on the above evidence and clues, Xu Lang first came to the following conclusions.

First, Li Chenghua was brutally killed in his own firewood room, and the murder weapon that killed Li Chenghua was the bloody firewood knife.

Second, the murderer of Li Chenghua is very likely to be a woman, or a man with a thin body and little strength, which is very in line with the characteristics of drug addicts, because every drug addict has been harmed by drugs for a long time, and their body organs and tissues have been persecuted by drugs, and their strength is not much, which is also normal.

Third, the murderer of Li Chenghua should be someone who is familiar with Li Chenghua, otherwise, Li Chenghua would not have been killed in the firewood room.

Fourth, the time of Li Chenghua's death was around December last year, at this time, Liu Yuanxiang was still working in J City and had no time to commit the crime, and Li Chenghua's adopted daughter Li Nianzhi was also working in other places at that time, and there was also no time to commit the crime.

However, although these four conclusions have been reached temporarily, there is still no way to lock the suspect, except for knowing the approximate time of death of the deceased and finding the scene of the first crime, no more useful clues have been found, and it is very difficult to solve the case in a short period of time, everyone's faces are not very good-looking, and Xu Lang raised several doubts after summarizing these news.

First, why is the money in Li Chenghua's wallet missing? And the other valuables in the family are not lost, could this be a murder of passion caused by a burglary case? Or is it a fake scene deliberately made by the murderer in order to confuse the direction of the police investigation after killing someone?

Second, who killed Li Chenghua? How did Li Chenghua get to the firewood house? Did he go to the firewood house of his own volition, or was he coerced to go? If it is the former, then it means that the murderer and Li Chenghua are acquaintances, and they are very familiar with each other, otherwise, Li Chenghua will not go to the firewood house in the presence of outsiders, if it is the latter, then it means that the murderer knows Li Chenghua's family very well, and it is very likely that it was premeditated murder, which is revenge homicide.

Third, the place where Li Chenghua's body was buried was actually in the deceased's own pigsty, why did the murderer do this? If it is an act of revenge, then the murderer is likely to be a person with a bad record, he must be a person who has been dealt with by Li Chenghua, or a prisoner who has been educated by Li Chenghua in prison, if it is a temporary choice under the panic, then it means that this is a murder of passion, which is a temporary homicide, otherwise, it is impossible to explain the fact that Li Chenghua was buried in his own pigsty, because ordinary people either choose to divide the body after killing people, If you try to destroy a corpse, you either choose to bury the corpse, and the choice to bury the corpse will generally choose to bury the corpse in some wilderness, or a place such as a large sea and canal, and not in a place where it is easy to be found.

When Xu Lang raised these questions, a new question emerged, whether the murderer of Li Chenghua was a murder of passion, a premeditated murder, an acquaintance who committed the crime, or a revenge murder, several different motives for the murder, so that the direction of the investigation began to develop in different directions.

After conducting a case analysis meeting, all the people in the 223 Serious Crime Team decided to focus on revenge homicide in the direction of investigation, for no other reason, mainly on the burial site of Li Chenghua, because Li Chenghua was buried in the pigsty, and this burial site was full of insulting and retaliatory connotations and ingredients, so the police conducted a key investigation on all the criminals who had bad criminal records.

The anti-narcotics brigade launched a series of investigations and evidence collection based on the possibility that the murderer might be a woman or a drug addict given by Ye Xuefei.

Qin Liangping's investigation went very smoothly, although there were many prisoners in the prison, but they were all centrally managed, and they were still serving their sentences, so they had no time to commit the crime, as for the motive for committing the crime, there must be no time to commit the crime, so they could only come to investigate and visit their relatives to see which prisoners had a grudge against Li Chenghua, and whether their relatives were likely to retaliate.

However, after some investigation, almost most of the prisoners were excluded, and a small number of prisoners, although they had a motive to commit the crime, and their family members also had a lot of complaints about Li Chenghua, but after some investigation and visits, it was found that these people did not have the time to commit the crime, and they all had sufficient alibi, and then, their suspicion of committing the crime was excluded.

As for those who have been released from prison, there are too many, and Ning Yanran has not had a definite answer for a while, because there are many prisoners serving sentences in Fengyun Prison, and Li Chenghua has been a prison guard in Fengyun Prison for not a day or two, a year or two years, but more than ten or twenty years, in these ten or twenty years, how can Li Chenghua have come into contact with thousands of prisoners, it is impossible to investigate clearly in a short period of time, in addition, every person released from prison after completing his sentence, They are not all locals of S City, and some of them are prisoners from other places, the main reason why they will serve their sentences in Fengyun Prison in S City is because they committed a crime in S City and were arrested and imprisoned in S City, so if you want to find these people, the workload is not ordinarily large, but, fortunately, with the cooperation of the police in various local cities, all the investigations are going smoothly, most of them have been found and summoned for questioning, but most of them have no time and motive to commit crimes, Some of them were released because they were released from prison very early, and if they wanted to take revenge, they would have done it a long time ago, so there was no need to wait that long, and some people were released after Li Chenghua's death, and they didn't have time to commit crimes, so after some investigation, the scope of investigation gradually narrowed.

In the end, after Ning Yanran and other police officers conducted a painstaking investigation, it was finally determined that half a year before Li Chenghua's death, there were about 30 people who had been released from prison, and the scope of the investigation was suddenly narrowed.

So, the police took these more than 30 people to the public security bureau for questioning, and in the process of questioning, one by one the suspects were gradually eliminated from suspicion, and from their mouths, the police found new suspects, and then according to their confessions, they found another group of suspects again, but they were still excluded one by one, and Ning Yanran's work fell into a deadlock at this time.

The suspects who are listed as suspects are all prisoners who have had a big or small holiday with Li Chenghua, but these problems are not a big problem, they are just some trivial things, of course, human nature is sometimes very terrible, and some murders are caused by one or more seemingly inconspicuous small things, although Ning Yanran They know that these contradictions and festivals do not seem to be a big deal, but the psychology of criminals cannot be figured out with common sense, especially murderers, So Ning Yanran and they didn't dare to have any slack and underestimate thoughts, after all, this is a matter related to a human life, but also the life of a retired policeman, this is related to the honor and majesty of the police, this is not only a matter of Li Chenghua alone, but also a matter of all police officers who struggle in the public security system, and they must not be neglected.

Remember the Ultimate Sin permanent address
