On September 11th, at ten o'clock in the morning, the members of the second criminal investigation team had already gone to work, and suddenly, a very embarrassed man covered in blood rushed in, pulled a police officer and shouted loudly: "I killed someone, I killed someone." ”

And this police officer who was pulled by the man was none other than Lu Xing, Lu Xing was about to eat some and buy a pack of chewing gum, but after being pulled by such a man who looked a little embarrassed and a little terrifying, Lu Xing was taken aback, he first greeted Zhang Lei and a new member of the second criminal investigation team, and the three of them took the man to the interrogation room of the second criminal investigation team, and after pouring a glass of water for the man and comforting the man, he began to ask what happened and why the man said that he had killed someone.

After drinking the water, the man gradually calmed down, looked at Lu Xing and them, and said with a very frightened expression: "I killed the person who killed my wife." ”

It turned out that this man's name was Niu Honghe, one year old Chinese New Year's Eve today, a worker in a mechanical processing factory in S City, his wife's name was Yu Jie, 29 years old this year, and the two of them also had a five-year-old child named Niu Jinglun, who was now in kindergarten.

On Saturday on the 11th, Niu Honghe's mechanical processing factory is not very good, no need to work overtime on Saturday and Sunday, he just rested at home, his wife Yu Jie used to be a factory worker, and later after getting married, Yu Jie resigned from the factory and started a housewife at home, Niu Honghe is a very distressed daughter-in-law, he thought that the child from birth to the present, almost all Yu Jie is taking care of alone, Niu Honghe is very upset, just yesterday he was on vacation, the child is going to the training class, Niu Honghe proposed to send his children to school, and Yu Jie agreed.

When Niu Honghe sent his son back from the training class, before entering the house, he heard an abnormal noise in the room, at that time, Niu Honghe felt a little strange, so he took out the key to open the door, and as a result, he saw a strange man appear in his home, his wife Yu Jie collapsed on the floor, covering his neck with both hands, and blood kept gushing out on Yu Jie's neck, and the strange man was wearing white gloves on his hand and holding a bloody fruit knife in his hand.

Niu Honghe saw his wife fall in a pool of blood, already less breath in and more breath, dying of the situation, Niu Honghe suddenly felt his head blow up, he shouted, desperately rushed into the house, and this strange man had a fierce fight, although Niu Honghe is working in a mechanical processing factory, but, he has a hobby, that is, he likes to contact Sanda, although he has not received serious training, but, Niu Honghe can still play more than ordinary people.

In the process of fighting, Niu Honghe snatched the fruit knife from the hand of the strange man, and in a hurry, a knife was inserted into the man's chest, and the knife was so immortal that it just pierced the man's heart, the fruit knife was not very strong, and after the knife was inserted into the man's heart, the knife was broken.

Niu Honghe didn't notice it at the time, what he was thinking about at the time was to avenge his wife, he stuck the man's neck with one hand, and kept hitting the man's chest and cheek with the other, until the man was stabbed, he had no ability to resist, and his body collapsed on the floor like a puddle of mud, Niu Honghe reacted, when he calmed down and went to see the man, he found that the man had a broken knife in his chest, and the man's eyes were wide open, and the corners of his mouth kept bleeding, and the man was dead.

After Niu Honghe saw this scene, he was so frightened that he sat on the ground, he was stunned for a long time, and then remembered that his wife didn't know what was going on, so when he crawled to his wife's side, he found that his wife Yu Jie's body had already begun to get cold, and Yu Jie had already died of excessive blood loss when Niu Hong was fighting with a strange man.

After Niu Honghe found out that his wife Yu Jie was dead, he sat in the living room holding his wife's body and cried bitterly.

Niu Honghe didn't know how long it took, he slowly calmed down, after looking at the corpse of the strange man who fell in his home, Niu Honghe didn't know what to do for a while, he said when he confessed, at that time, he really wanted to commit suicide to understand his life, since ancient times, killing people to pay for their lives, paying off debts, killing people themselves, if they were known, they would definitely have to pay for their lives, but when he raised his head and saw the photo of his son hanging in the living room, Niu Honghe didn't dare to die, What to do with his dead son?

Niu Hong confessed to himself, at that time, he didn't expect to run away with his son, but, Huaxia is so big, once someone finds the two bodies in the family, he will definitely call the police, when the police come, the first suspect must be the male owner of the house Niu Honghe, at that time, many things Niu Honghe felt that he must not be clear, so Niu Honghe After a fierce ideological struggle, he came to the Public Security Bureau to surrender.

After Lu Xing and the others listened to Niu Honghe's story, Zhang Lei immediately took people to Niu Honghe's house, sealed the scene, and investigated the scene.

After Zhang Lei arrived at the scene, he saw that the situation was basically the same as what Niu Honghe said, Niu Honghe's wife Yu Jie was lying in the living room in pajamas, Yu Jie had a large pool of blood under Yu Jie's body that had not completely dried up, Yu Jie covered her neck with her hands, her hands were stained red with blood, and the blood stains were half dry, the blood stains became a little black, and the pajamas on the woman's body had already been stained red with blood, the woman was wearing slippers on one foot, one foot was bare, and her other slippers didn't know where it went. And in the living room to the door, there is a male corpse wearing camouflage uniform, the man is lying on his back on the floor, the man is about his early thirties, with a pointed beak and monkey gills, his body is very thin, his face is sallow, and it is caused by long-term malnutrition.

The man's eyes were wide open, one eye was black, the corners of his mouth were broken, and blood was flowing from his nose, and there was a broken knife inserted in the man's chest, and the knife had completely pierced the man's chest.

In addition to the two corpses found in Niu Honghe's home, the living room was also a mess, the sofa was knocked to pieces, the sofa cushions and pillows on the sofa were also scattered on the ground, and the coffee table was also hit into the corner, all the things on the coffee table fell to the ground, and some glass products had already been shattered, and there were blood stains and glass ballasts all over the ground.

When Zhang Lei asked people to investigate the scene in the living room, he found that there was a string of bloody footprints in the house, which had been to the bathroom from the living room and to the bedroom, and finally stayed by the side of the female corpse for a long time, and in the second bedroom, many things were turned into a mess, and it seemed that it should be done by the strange man.

After a simple investigation, a wad of cash was found on the man's body, probably more than two thousand yuan, some of which were whole, and in addition, several pieces of jewelry that were not particularly valuable were also found on the man's body, which were all used by women, and after investigation, they should be the things used by the hostess Yu Jie before her death.

After the forensic doctor preliminarily examined the bodies, he brought the two bodies back to the Public Security Bureau, and the identity of the hostess was carried out after the police came here, and when they were carried out, the neighbors who came to watch recognized the identity of the woman and knew that she was Niu Honghe's wife Yu Jie, and the identity of the other man, no one knew, however, Zhang Lei and they quickly found out the identity of the man.

The man's name is Jiang Zhengye, Chinese New Year's Eve this year, is a habitual burglar, he is an orphan, fatherless and motherless, has been stealing since the age of fifteen, is a frequent visitor to the public security bureau and the police station, and he has been repeatedly dealt with by the public security organs because of petty theft, has been in a juvenile detention center, has also been administratively detained, and has also been in prison, the last time he went to prison was three years ago, because of burglary, he stole more than 30,000 yuan from the master's family, and when he left, he was discovered by the owner who happened to come back temporarily, and Jiang Zhengye was also unlucky, This man is not only a sanda master, but also a karate master, Jiang Zhengye was subdued on the spot and sent to the Public Security Bureau, and Jiang Zhengye was also sentenced to three years in prison because of this incident, and he was released not long ago.

originally thought that Jiang Zhengye would be restrained after this encounter, and after he came out, he changed his mind and became a new person, but what he didn't expect was that he started burglary again as soon as he came out, but this time it was not as simple as sending another master's family to the public security bureau to go to jail, but directly threw away his life.

Originally, after figuring out the identity of the strange man and learning that he was a habitual thief, almost everyone thought that this case should belong to Jiang Zhengye's burglary, and was discovered by the hostess, I don't know if it was because he killed the hostess by mistake, or killed him in order to kill his mouth, in short, Jiang Zhengye brutally killed Yu Jie, and this scene happened to be seen by Niu Honghe, who had just sent the child home.

The facts of the case seem very clear, whether it is logically or in the chain of evidence, it makes sense, at that time, after Zhang Lei finished investigating the scene, he returned to the second criminal investigation team and announced that the case could be closed, as long as a closing report was written, Niu Honghe was handed over to the judicial organs, Niu Honghe belonged to legitimate defense, plus Jiang Zhengye killed Niu Honghe's wife, and when he was tried in court, it is very likely that he will not have to bear legal responsibility, which is a good thing for Niu Honghe, but in the subsequent investigation, The police found something strange.

First, when the police investigated Niu Honghe's house, Niu Honghe's doors and windows were intact, and there were no traces of prying the window and prying the door, and Niu Hong and their family book lived on the fifth floor, and the houses in the Lvhua community were equipped with anti-theft nets, and ordinary people could not enter, of course, the anti-theft nets were only installed on the third floor, and they were not installed on the top. As for the door, it has not been pried at all, so how did Jiang Zhengye get in?

Second, the profession of thief, generally choose to commit crimes at night, while the owner is asleep, burglary in the dead of night, in this way, not only the risk of being found is reduced a lot, and, under the cover of night, first, it will not be easy to be seen clearly, second, even if it is seen, you can also escape the scene under the cover of night, few thieves will choose to do it during the day, and it is on Saturday.

Third, there is no trace of Niu Honghe's master bedroom being turned over, but the cash and Yu Jie's jewelry placed on the bedside table are not in the original place, but on Jiang Zhengye's body, and the second bedroom is their son Niu Jinglun's room, how can there be so much cash and jewelry in the child's room? Moreover, the decoration of the second bedroom looks like a child's room, Jiang Zhengye is not the first time to steal things, he is a habitual thief, he naturally knows where ordinary people will put their money, he has no need to turn the second bedroom into a mess.

Fourth, although Jiang Zhengye wore the white gloves used in the crime, he did not wear shoe covers, if he went to the master bedroom or the second bedroom, he would definitely leave footprints, but when the police investigated the scene, they did not find Jiang Zhengye's footprints on the floor of the master bedroom and the second bedroom, only the footprints of Niu Hong and a family of three.

Fifth, there was a fierce fight in the living room, at least it seemed like this, but after Li Lei found out the previous problem, when he went to investigate the scene again, he felt that the living room gave people a very unnatural feeling, those sofa coffee tables that were turned over, as if they were deliberately put in that way, and, according to Niu Honghe's account, when he was fighting with Jiang Zhengye, he quickly snatched the fruit knife from Jiang Zhengye's hand, and he had already inserted the knife into Jiang Zhengye's chest at that time, so, If this is the case, then there should be Jiang Zhengye's blood stains on the sofa and on the coffee table, in addition, there were many glass shards in the living room at that time, and when the forensic doctor investigated Jiang Zhengye's body, he found that he had one foot without shoes, and the lost shoe was in the corner of the living room, and there were no glass shards on his feet, nor were they scratched by glass, which looked very abnormal.

Sixth, whether it was Jiang Zhengye who was discovered by the hostess when he was burglarizing, and the two had a conflict, or Niu Honghe went home and had a fight with Jiang Zhengye, during this period, there would definitely be a sound of movement, and the eleventh was not the time to go to work, after the neighbors heard the noise, it was impossible not to come out to see, even if they didn't come out to see, they would hear something, and when the police were investigating and visiting, no one heard any strange or loud noises from Niu Honghe's home, At nine o'clock in the morning, she heard two sounds of things breaking from Niu Honghe's house, and at that time, she was still standing outside Niu Honghe's house and asked what was going on inside, but no one in the room answered, and she didn't care, so she left.

When the police found these unusual places, they had a new idea for Zhang Lei's view that the case could be closed at the beginning, and Li Lei returned to the second criminal investigation team after re-investigating the scene, and found Niu Honghe again for interrogation, after raising these questions, Niu Honghe suddenly quieted down and didn't say a word, no matter what Li Lei asked him, he kept his mouth shut, and the interrogation work has continued from yesterday noon to the present, and there is still no progress at all. Niu Honghe should still eat, drink, just don't answer the question, insist that he is in legitimate defense, when it's time to sleep, he starts to sleep, not at all like a normal person who has experienced the normal reaction of his wife being killed, and he accidentally kills someone, Niu Honghe behaved too calmly, too calm, too calm, he was calm and incredible.

So, Ning Yanran and the others started to try and investigate this case again, they were no longer the subjective speculation of the murder case caused by Jiang Zhengye's burglary when they first came into contact with this murder case, they began to doubt whether Niu Honghe was the murderer who really killed his wife Yu Jie and Jiang Zhengye.

Because of Niu Honghe's silence, the rest of the second criminal investigation team went out to find Niu Honghe's neighbors and colleagues to visit and investigate, so when Xu Lang came to the second criminal investigation team, he didn't see a single person.

After Xu Lang looked at these things, after pondering for a moment, he looked at Ning Yanran and asked, "Do you suspect that Niu Honghe killed his wife Yu Jie?" ”

Ning Yanran nodded and said, "This is just one of the speculations, and the other is ......"

"Hire a murderer, and then kill someone." Xu Lang answered.

Ning Yanran turned her head, looked at Xu Lang and nodded.

Xu Lang frowned and asked, "Then what is Niu Honghe's motive for committing the crime?" ”

Hearing Xu Lang's question, Ning Yanran said with a wry smile on her face: "It's because I can't find a motive for the crime that I called you over." ”

"Husband and wife are not compatible?" Xu Lang asked tentatively.

Ning Yanran shook her head and said: "According to our investigation, Niu Honghe and Yu Jie have always had a good relationship, although the economic conditions of the two are not good, but they are a model couple in the Lvhua community." ”

When Xu Lang heard this, he frowned, thought for a while and asked, "Did Yu Jie cheat and cuckold Niu Honghe, Niu Honghe was angry for a while, so he ......?"

Ning Yanran shook her head again and said: "Yu Jie doesn't know many people, the factory she used to work in was an electronics factory, and the workshop where she worked was all women, almost no men, and Yu Jie didn't look very beautiful, it can only be said that in general, after she got married, she became a housewife, except for taking care of the children at home, just cleaning up the housework, there is no chance or condition to meet other men." ”

Hearing Ning Yanran say this, Xu Lang fell into deep thought, and subconsciously rubbed his chin.
