With the passage of time, as the investigation deepens, the suspects who are locked in suspicion are excluded one by one after being listed as suspects, and more and more suspects are being investigated, and the scope of the investigation is gradually narrowing.

In the blink of an eye, ten days have passed, ten days have passed since the establishment of the 2.23 Serious Crime Team, and ten days have passed since Li Chenghua's body was found.

Ten days later, the investigation came to an end, with the efforts of all the staff, over the years, the prisoners who had contact with Li Chenghua were investigated one by one, but still no suspicious persons were found, although during this period, many people who were released from prison were listed as suspects, but after some interrogation, it was found that the reason why they did not know where they were when Li Chenghua was killed was because they committed the crime again after they were released from prison.

At the beginning, during the interrogation, they also looked at other things, and they were reluctant to tell the truth to death, but when they learned that there was a murder case, and the person who was killed was a retired policeman, they had to open their mouths to honestly explain the problem, after all, during this period, they committed small cases such as robbery and theft, and they came out after a few years in prison at most, but the murder case is to be sentenced to death, which is more serious, they are people who have served their sentences in prison and studied law, not legally illiterate, They are well aware of this.

The results of the investigation are disappointing, but it is still a matter of joy to solve some cases that have not been discovered or solved before, however, Li Chenghua's case still has no clue.

March 4th, I don't know if this is the first case analysis meeting held by the 2.23 serious crime team, at the scene of the analysis meeting, everyone's faces are very tired and ugly, tired because during this time, everyone's nerves have been in a tense state, has been in a high level of tension, people are not machines, they are flesh and blood creatures, fatigue is inevitable, ugly because, in such a dragnet, sieve-like investigation, there was no suspect who was consistent with Li Chenghua's death, and it was false to say that he was not discouraged, but even if he was discouraged, uncomfortable, and difficult, the investigation still had to continueSeeing that the fifteen-day deadline given by Lu Ye to solve the case is getting closer and closer, everyone is under a lot of pressure.

The room was silent and smoky, except for the occasional cough, except for the rustle of the tip of a pen across paper.

The lack of results from the investigation is a problem that no one expected, and Xu Lang is the same, but what makes Xu Lang feel strange is that since all the prisoners that Li Chenghua has contacted in the past few decades have been screened, and no criminal suspect has been found, who will be the murderer of Li Chenghua? Could it be that the investigation team of these people in charge of the investigation was negligent in its work?

Xu Lang thought of this and shook his head, he felt that it was impossible, because it was not only Ning Yanran and them who participated in this investigation, but also people from the anti-drug brigade and people from Fengyun Prison worked together, but with the cooperation of several departments, no suspect was found, so does it mean that Xu Lang had a problem in the direction of the investigation, could it be that Li Chenghua's death was not a revenge killing, nor a premeditated killing, but a passion killing, could it be an acquaintance who committed the crime?

So, Xu Lang put forward his idea, and when Xu Lang put forward this idea, everyone in the 2.23 serious crime team shook their heads, and they all nodded after carefully chewing Xu Lang's words.

Indeed, when they found out that Li Chenghua died tragically in their own home, especially after seeing the place where Li Chenghua's body was found, they could not forget that Li Chenghua was a policeman, and everyone had a preconceived idea that Li Chenghua's death must be related to the criminals he had dealt with and managed, thus ignoring the possibility of the simplest acquaintances committing crimes and killing people in passion, of course, This can't be blamed on the people of the 2.23 Serious Crime Team who didn't expect this, mainly because the place where Li Chenghua's body was found was too infuriating, over the years, there have been cases of prisoners retaliating against the police in Huaxia Province, although there are not many, but there are still frequent cases, not to mention, Li Chenghua used to be an anti-narcotics policeman, and because of this, he has made collective second-class merits and individual third-class merits and first-class merits, and it is not surprising that the people of the Serious Crime Team will be preconceived.

After ten days of dragnet-style and sieve-like investigation, since no criminal suspect was found, it means that the judgment of revenge homicide given by the previous serious crime team was wrong, and it is very likely that the murderer of Li Chenghua was an acquaintance around Li Chenghua, so the serious crime team began to readjust the direction of the investigation according to the opinions put forward by Xu Lang, and launched a detailed investigation of the people around Li Chenghua. There may be some unexpected surprises and gains.

When the serious crime team adjusted the direction of the investigation, the first thing they thought of was Li Chenghua's wife Liu Yuanxiang, although she was the first person to find Li Chenghua's disappearance, and the first person to find Li Chenghua's body was also her, saying that she was not suspected, it was impossible, in countless cases, the first person to find the body and report the case was very likely to be the murderer, this is not a whimsy, but based on the experience summarized from countless cases.

Thinking of this, the police summoned Liu Yuanxiang again and asked her to explain her specific whereabouts before and after Li Chenghua's death, and Liu Yuanxiang did not object, 1510 told her where she was at the time, what she did, how she found her husband Li Chenghua's disappearance, how she searched for it, and how she finally found Li Chenghua's body.

The police will definitely not believe Liu Yuanxiang's words, after all, everything must pay attention to evidence, so the idiom of the serious crime team immediately rushed to the city where Liu Yuanxiang worked and went to the factory where Liu Yuanxiang was located to conduct a detailed investigation.

After some investigation, it was found that Liu Yuanxiang did not lie, because Liu Yuanxiang went to work in other places at the beginning of last year, and returned home at the end of the year, which can be proved not only by the leaders of the factory, but also by the colleagues who worked with Liu Yuanxiang, and even when Liu Yuanxiang left the factory, and the workers in the dormitory with Liu Yuanxiang remember it clearly, which shows that Liu Yuanxiang did not have the time to commit the crime, and according to the investigation, the relationship between Liu Yuanxiang and Li Chenghua has always been very good. Although two people usually quarrel and contradict because of some trivial things in the family, as the saying goes, husband and wife do not have overnight feuds, quarrels are quarrels, which is a normal thing among married people, Liu Yuanxiang will not kill her husband who has lived together for decades for a little bump in life, let alone bury him in a pig manure heap after killing Li Chenghua, which is completely unnecessary.

Since Liu Yuanxiang's investigation has no results and ruled out Liu Yuanxiang's suspicion of committing the crime, could it be that Li Chenghua's neighbors have any opinions about Li Chenghua?

Thinking of this, the police investigated all the people in Li Chenghua's village again, and the results of the investigation showed that Li Chenghua is a very good person, he is not only very good to his colleagues, but also treats prisoners well, and treats the people around him very well.

In the decades that Li Chenghua has settled in S City, Li Chenghua has not really blushed with anyone, if there is, that is, when playing chess, Li Chenghua will quarrel with the chess player because of a wrong move, but the quarrel is a quarrel, even if the quarrel is red and the neck is thick, the next day, the two will still sit together and continue to play chess.

When the investigation came to this point, everyone in the serious crime team began to wonder if there was another problem with the direction of the investigation.

After learning of these findings, Xu Lang was once so suspicious, but he soon discovered new suspicions.

Xu Lang thought of a person, this person, whether it was when Li Chenghua disappeared or after Li Chenghua's body was found, she did not appear from beginning to end, and she was not investigated by the police, she was Li Chenghua's adopted daughter Li Nianzhi.

In fact, Xu Lang will suspect that Li Nianzhi is not unreasonable, first, according to the general situation, when the children learn that their father is missing, as a child, they must return home as soon as possible to help find it together, even if they can't come back, they will call to inquire, but Li Nianzhi did not choose to do this, not only did she not go home, but during the Chinese New Year, she just made a phone call to Liu Yuanxiang, and did not even ask Li Chenghua the words, which is very strange.

Second, after Li Chenghua's body was discovered, Liu Yuanxiang once told Li Nianzhi the news, but after she heard it, she was not surprised and surprised, but said lightly I know, there is no follow-up, at this time she did not choose to go home, but continued to stay in the field, this is very abnormal, although Li Chenghua is not Li Nianzhi's biological father, but he is also the adoptive father who raised her with a handful of and urine, no matter what, she should also come back after the death of her adoptive father.

Third, after the readjustment of the direction of the investigation, the police found that the relationship between Li Nianzhi and Li Chenghua was not very good, not because Li Chenghua didn't like this daughter, but because Li Nianzhi was too disobedient and too discouraged, according to the memories of the neighbors, they had seen Li Chenghua and Li Nianzhi have had fierce quarrels at home several times, and the reason for the quarrel seems to be because Li Nianzhi began to go to school well and began to fall in love when he was in junior high school. As for the specifics, they do not know.

Therefore, after Xu Lang thought of Li Nianzhi, he said his thoughts, after the investigation of Li Chenghua's case entered an impasse, Xu Lang's investigation direction may find something, although people who know Li Chenghua don't believe that the person who killed Li Chenghua will be his daughter who is afraid of falling off in the palm of his hand and holding it in his mouth for fear of melting, but there are more and more suspicious points in Li Nianzhi's body, and he has to investigate.

So, the 2.23 Serious Crime Team launched an investigation into Li Nianzhi's interpersonal relationships, which is not an investigation, and this investigation found that Li Nianzhi's child has many problems, and the suspicion has gradually risen.

Previously, Qin Liangping, the warden of Fengyun Prison, had briefly mentioned Li Nianzhi's situation on the phone to Xu Lang, and when the serious crime team began to investigate Li Nianzhi, they found a lot of unknown information.

Li Nianzhi was an abandoned baby raised from the hospital when Li Chenghua was forty-three years old, because Li Nianzhi was born disabled, so he was abandoned by his parents, and Li Chenghua's wife Liu Yuanxiang could not have children because of his body, Li Chenghua's parents' thinking is still relatively traditional, as the so-called, there are three unfilial pieties, and no queen is the greatest, so when Li Chenghua has been married for so many years and has not yet had a son and a half daughter, the elderly parents began to urge Li Chenghua to find a way to have a child.

In fact, not only Li Chenghua's parents are anxious, Li Chenghua and Liu Yuanxiang are also anxious, Liu Yuanxiang is a very virtuous woman, she thought that she could not have children, and she had filed for divorce with Li Chenghua several times, asking Li Chenghua to find another woman to marry and have children, but Li Chenghua sternly refused, and was scolded by Li Chenghua, since then, Liu Yuanxiang has never mentioned divorce.

Later, Liu Yuanxiang heard that people could spend money to buy a child, so she mentioned it to Li Chenghua, but what she didn't expect was that after Li Chenghua heard Liu Yuanxiang's suggestion, he was angry in front of Liu Yuanxiang for the first time, and he was almost about to beat someone, this is the first time Liu Yuanxiang and Li Chenghua got married, and it was the first time she saw Li Chenghua so angry, so since then, she has never mentioned this matter, but Liu Yuanxiang and Li Chenghua also have an estrangement between husband and wife because of the child, which is also normal and clear.

Later, Li Chenghua didn't know where he learned that there was a discarded abandoned baby in the hospital, Li Chenghua rushed to the hospital, and after going through a series of procedures, adopted the child, originally, Li Chenghua thought that since Liu Yuanxiang could not give birth, and could not buy and sell children, after all, buying and selling babies is illegal, and Li Chenghua is a policeman, let alone knowing the law and breaking the law, what I didn't expect was that when Li Chenghua took Li Nianzhi home, not only Liu Yuanxiang was unwilling to adopt the child, Even Li Chenghua's parents were unwilling, for no other reason, first, this child is a girl, and she will definitely marry in the future, and second, because this child was born with a disability, a rabbit mouth, and she looks too bumpy and ugly, otherwise her biological parents would not have abandoned her.

After Li Chenghua hugged Li Nianzhi back, Liu Yuanxiang said directly: "If you keep this child, we will divorce and raise you yourself, but I won't raise you." ”

Although the adoption of Li Nianzhi was opposed by his family, the threat of his wife, and even his friends and colleagues persuaded him to return the child to the hospital or to the orphanage, Li Chenghua did not do it, at that time, Liu Yuanxiang had not come to S City, but took care of both parents in his hometown, Li Chenghua had no choice, so he took Li Nian back to S City alone, a person who was both a father and a mother, and raised Li Nianzhi with a handful of and urine.

Li Nianzhi was still very young at the time, only a few months old, and the child was small, what should he do if he couldn't eat like an adult? Li Chenghua became a beggar father, he took the child every day to go to the pregnant women who had just given birth to a child, to beg for milk-water to drink, at first, Li Chenghua was quite embarrassed, after all, a big man alone with a child in a group of women mixed in a pile is not a glorious thing, not to mention that it is embarrassing to be with a group of women, even these husbands who have just become mothers are very uncomfortable when they see it, and when they are breastfeeding their children, if they are all women together, there is nothing to be embarrassed about, But a big man was stunned, and it was very embarrassing.

However, women are very great, especially women who are mothers, after they have children, when they see children who are similar to their own children, maternal love is very overflowing, so when Li Chenghua took Li Nianzhi to be a beggar father, these kind women are not stingy with a mouthful of milk-water, just like that, Li Nianzhi grew up eating a hundred family meals, and Li Chenghua was also more famous at that time, and the name of the beggar father was derived from this.

When Li Nianzhi grew up, Li Chenghua stopped being a beggar father, and began to feed Li Nianzhi milk powder and drink, Li Chenghua completely regarded Li Nianzhi as his own child, he took out his salary to buy the best milk powder and clothes for Li Nianzhi, but it must be very hard for a big man to take care of a half-old child, and he often made Li Chenghua busy and anxious.

Liu Yuanxiang was very opposed to Li Chenghua's adoption of Li Nianzhi at first, but when she saw that her husband loved Li Nianzhi so much, she was also a woman, and her mother's love was overflowing, and she gradually accepted this ugly-looking child, after the child was weaned, she came to S City and took care of Li Nianzhi with Li Chenghua, and Li Chenghua's parents gradually got used to the child's joining, and began to slowly accept this child, so to speak, whether it is Li Chenghua himself, or Liu Yuanxiang, or Li Chenghua's parents, There are also those mothers who have given Li Nianzhi's milk-water, they are the kindest, loveliest, and most respectable group of people.
