After the Bu Zimo case in the second criminal investigation team, the three new members joined, respectively, are Hu Anyun, twenty-three years old this year, just graduated from the police academy, her university and Xu Lang once stayed in the same school, strictly speaking, Xu Lang is her senior, the other looks the youngest, named He Liangping, twenty-eight years old this year, he looks very young, in fact, he has been working in the criminal investigation work for six or seven years, he is an old driver, as for the last has been silent, bright-eyed newcomer is called Guo Jun, is a retired soldier of a special forces in China, once made a second-class merit, and two third-class merits, but in the end he was injured in a certain mission, and finally had to choose to retire, because Guo Jun's resume is very good, and he was finally arranged to the second criminal investigation team.

It's just that Xu Lang doesn't know these things for the time being, and after listening to Hu Anyun's story, he pondered for a moment and asked: "So, Niu Honghe actually has an extremely extreme duality in the eyes of different people, right?" ”

Everyone asked this, thought about it, nodded, and agreed with Xu Lang's statement.

According to the results of Zhang Lei's visit, Niu Honghe's most obvious characteristics are that he is taciturn, has very good work skills, has no friends, has no bad habits, does not smoke, does not drink, does not gamble, goes to work on time every day, and gets off work on time after arriving at the point. Niu Honghe has a very serious tendency to violence, and often commits domestic violence against Yu Jie, which is where the controversy lies.

Thinking of this, Xu Lang suddenly looked at Ning Yanran, and Ning Yanran seemed to go with Xu Lang, she also raised her head to look at Xu Lang, Xu Lang said, "Haven't Yu Jie's autopsy results been made yet?" ”

Ning Yanran nodded, she looked at Xu Lang, the two of them had been to the forensic autopsy room before, they only cared about the death of the male deceased Jiang Zhengye at that time, and paid little attention to the female deceased Yu Jie, at that time they did not ask Ye Xuefei if there were any traces left by long-term domestic violence on Yu Jie's body, thinking of this, Ning Yanran said to Zhu Xumei: "You go to the forensic doctor to bring the autopsy report, if Forensic Ye has not yet issued the autopsy report, you can ask, Is there any scar on the body of the deceased Yu Jie that has been subjected to domestic violence for a long time? ”

Zhu Xumei stood up and walked towards the forensic office, while Xu Lang and the others continued to discuss the case.

Ning Yanran saw that Xu Lang was silent, so she looked at everyone and asked, "Who went to visit Niu Jinglun's teacher?" ”

Zhang Lei raised his hand and said, "I'll go." ”

"Have you collected any biological samples from Niu Jinglun?" Ning Yanran asked.

"After collecting, I have sent it to the technical department, and it is estimated that the data is now being compared with Niu Honghe's DNA, and it is estimated that the results will be available a little later." Zhang Lei said.

Ning Yanran nodded, and asked again, "What does Niu Jinglun's teacher say about Niu Jinglun's parents?" ”

"Niu Jinglun's teacher has not had much contact with Niu Honghe and Yu Jie, when she first saw Niu Jinglun, it was Yu Jie who took Niu Jinglun to go, the child is very homesick, but very sensible, and he doesn't cry or make trouble when he goes to the training class, and he is much more obedient than ordinary children." Zhang Lei said.

"Niu Jinglun has been picked up by Yu Jie since he went to the training class?" Xu Lang interjected.

Zhang Lei nodded and said, "Yes, Niu Jinglun's teacher was very strange yesterday, why was it a man who sent Niu Jinglun today, but she didn't care too much when she saw Niu Jinglun calling him Dad." ”

"Then did Niu Honghe behave abnormally at that time?" Xu Lang continued to ask.

Zhang Lei thought about it, flipped through the notebook in his hand, then shook his head and said, "No, Niu Jinglun's teacher is also the first time to see Niu Jinglun's father, and she doesn't have a deep impression of Niu Honghe." ”

When Xu Lang heard this, he didn't ask any more, and the office area of the second criminal investigation team fell silent for the time being.

It didn't take long for Zhu Xumei to come in with the autopsy report, I don't know what she thought, it stands to reason that Ning Yanran is her leader, but after the autopsy report was brought, she handed it to Xu Lang for the first time, Xu Lang took it and looked at it, and Ning Yanran, or Li Lei, did not have any dissatisfaction with Zhu Xumei's action, but felt that it should be taken for granted, after Hu Anyun saw this scene, her eyes moved slightly, and she took a deep look at Xu Lang, who was frowning with the autopsy report.

There are not many contents of the autopsy report, most of which are what Xu Lang and Ning Yanran learned about in the autopsy room before, and the autopsy report of Yu Jie, which Xu Lang is more concerned about, clearly states that in addition to a fatal knife wound on Yu Jie's neck, Yu Jie also found a lot of old wounds on Yu Jie's body, most of which were caused by beatings, these locations are mainly concentrated in Yu Jie's chest, abdomen, and arms and thighs, and Yu Jie's arms have many traces of being burned by cigarette butts, which looks particularly terrifying.

After reading the autopsy report, Xu Lang raised his head, handed the autopsy report in his hand to Ning Yanran, and then said: "The traces left after the domestic violence were found on Yu Jie's body, which shows that Yu Jie's friend did not lie, and Yu Jie was indeed subjected to long-term domestic violence by Niu Honghe." ”

Hearing Xu Lang say this, everyone looked at each other and felt a little surprised, Niu Hong and I have all seen it, belonging to the stuffy gourd type, a person who can't beat a fart with a stick, the first impression of the police officers of the second criminal investigation team when they saw Niu Honghe was that this guy was an honest man at first glance, but the current investigation results show that Niu Honghe is not as honest as he seems on the surface.

Xu Lang stood up, walked to a blackboard, picked up a pen, and wrote down three names in a row, Yu Jie, Jiang Zhengye, Niu Honghe, after Xu Lang finished writing, he said: "Yu Jie, was she killed by Jiang Zhengye, or was she killed by Niu Honghe?" ”

After Xu Lang finished speaking, he circled Yu Jie's name, and then put a question mark, and then he circled Jiang Zhengye's name and said, "Why did Jiang Zhengye appear in Niu Honghe's house?" Was it burglary, or was there another reason? ”

Finally, Xu Lang put the pen under Niu Honghe's name and said, "Why did Niu Honghe commit domestic violence against Yu Jie? And why didn't Yu Jie choose to leave Niu Honghe and choose to continue to endure domestic violence? Also, after Niu Honghe surrendered, whether what he said was the truth is still up for debate. ”

When Xu Lang said this, he looked at everyone and asked, "What do you think about Niu Hong and this case?" ”

Li Lei is the deputy captain of the second criminal investigation team, and Niu Honghe's interrogation work is in charge of him and Zhu Xumei, Li Lei said: "I personally think that the deaths of Yu Jie and Jiang Zhengye are definitely not as simple as Niu Honghe said, there is another hidden story here?" ”

Xu Lang looked at Li Lei and asked, "Tell me your reason." ”

Others also looked at Li Lei.

Li Lei said slowly: "He is too calm, calm is not like a performance of suffering from the pain of losing his wife and killing people, from he came to the Public Security Bureau to surrender, until now, nearly thirty hours have passed, ordinary people after the sudden change, especially after killing someone, when they face our police interrogation, they will generally show great panic and uneasiness, definitely not like Niu Honghe, so calm, should eat, drink, sleep, simply treat our Public Security Bureau as his home, I think that since Niu Honghe often committed domestic violence against his wife Yu Jie, then he had a motive to commit the crime. ”

After Xu Lang listened, he wrote 'domestic violence' on the blackboard, and then Xu Lang looked at the others and asked, "What else do you think?" ”

After Li Lei said his opinion, no one else said anything, and at this moment, Guo Jun, who had been silent, suddenly said: "I suspect that Niu Honghe and Jiang Zhengye know each other, or that there is some kind of transaction between them." ”

Xu Lang looked at Guo Jun, nodded, and said: "Your speculation is very good, according to the results of the investigation at the scene, Jiang Zhengye entered Niu Honghe's house through formal channels, this is a suspicious point, next, you can investigate along the social relationship between Niu Honghe and Jiang Zhengye, maybe there will be unexpected gains." ”

Guo Jun nodded and didn't say anything more.

Hu Anyun saw that Guo Jun had spoken, and she was not far behind, and as soon as Xu Lang's voice fell, she said: "Since Niu Honghe has been committing domestic violence against Yu Jie for a long time, let's investigate from this aspect to see why Niu Honghe committed domestic violence against Yu Jie and what the reasons are." ”

Xu Lang nodded and agreed with Hu Anyun's idea.

Next, other people also expressed their opinions, and in summary, everyone began to doubt Niu Honghe, feeling that the murder caused by the burglary was not as simple as it seemed.

At the end of the short meeting, Xu Lang and Ning Yanran proposed a new direction for detection.

First, investigate the real relationship between Niu Honghe and Yu Jie, and figure out why Niu Honghe committed domestic violence against Yu Jie.

Second, find out whether Niu Jinglun and Niu Honghe belong to the father-son relationship, if so, then it is necessary to investigate the case from other directions, if not, then who is Niu Jinglun's real father?

Third, find out Jiang Zhengye's activity trajectory during the period from his release from prison to the discovery of his body, find his residence, and see if he continues to commit theft after he is released from prison this time.

Fourth, figure out the relationship between Jiang Zhengye and Niu Honghe, see if they know each other, if they do, then the nature of this case will completely change, if not, then how did Jiang Zhengye enter Niu Honghe's house?

And these four points are the current direction of the second criminal investigation team, as for Niu Honghe's interrogation work, since there is no progress on the police side now, then, after Ning Yanran and they figure out these four questions, it will not be too late to interrogate Niu Honghe, and when the time comes, in front of all kinds of evidence, it is impossible for Niu Honghe not to speak.

After the meeting, Zhang Lei and the others began to act separately, while Xu Lang found Li Lei and said, "Take me to the scene of the crime." ”

Li Lei looked at Xu Lang and asked, "Do you want to investigate the scene?" ”

Xu Lang nodded, noncommittal.

So, Li Lei left the second criminal investigation team with Xu Lang and Zhu Xumei and drove to the scene of the crime.

Lvhua community is an old-fashioned community, the structure of the residential buildings is also very old, and because of this, the housing prices here are very cheap, on the way to go, Li Lei told Xu Lang that Niu Honghe's house was half sold and half given to him by his master, otherwise, it is impossible to afford it with Niu Honghe's economic ability.

At that time, Xu Lang asked curiously: "What is the name of this master of Niu Honghe?" What is the relationship between the two of them? ”

"It seems to be called Diao Jian'an, and his relationship with Niu Honghe looks like a master and an apprentice on the surface, but in fact, they are more like father and son." Li Lei said while driving.

"Father and son? Could it be that Niu Honghe is Diao Jian'an's son? Xu Lang asked puzzled.

Li Lei shook his head and said: "They are not blood related father and son, Diao Jian'an used to have a son, but his son died in an accident, so Diao Jian'an has no children, and Diao Jian'an's temper is a little weird, and he doesn't get along well with others, but only this Niu Honghe is very good, and Niu Honghe's current technology is taught by Diao Jian'an, Niu Honghe lives in this house now, it used to be Diao Jian'an's marriage room for his son, but then his son died, Diao Jian'an regarded Niu Honghe as his half son, and when Niu Honghe and Yu Jie got married, Diao Jian'an sold this house to Niu Honghe, and Niu Honghe only paid less than 200,000 yuan at that time, so he bought this house. ”

After Xu Lang listened, he understood what was going on, Xu Lang didn't ask anything, just silently wrote down the name Diao Jian'an.

Lvhua community is not far from the Public Security Bureau, they have arrived at the scene when they are talking, because it is an old-fashioned residential building, so there is no elevator, they had to climb the stairs upstairs, when they came to Niu Honghe's door, they found that the door was open, and there was a cordon outside the door, there was a police officer in charge of guarding, the police saw Xu Lang after them, hurriedly said hello, Xu Lang nodded slightly, it was a response.

Xu Lang entered the scene after putting on shoe covers and gloves.

Before, when Xu Lang looked at the photos, he didn't think the scene was complicated, but now, after others arrived at the scene, they found that the scene was really a mess, from the door to the living room, there were blood stains everywhere, because the slightly dull yellow wall was also stained with blood stains, and from a distance, it looked like someone had sprinkled red paint on the wall, which was particularly dazzling.

Xu Lang stood at the door, the first thing he saw was a human-shaped outline line, this should be the place where Jiang Zhengye's body was found, there was a large pool of dried blood next to the line, Xu Lang carefully avoided these lines, walked into the living room, standing in the living room, Xu Lang found that there were blood stains on the floor from the bedroom to the door, and from the door to the living room and finally to the sofa, there were three very dark drag marks, as if someone had climbed on the ground, and at the door of the bedroom, There was another humanoid line, and that was where the body of the female deceased Yu Jie was found, and in that area, there were a lot of blood stains.

In the living room, the sofa and coffee table fell to the ground, and the floor was covered with broken glass, and on these things, Xu Lang was surprised to find that whether it was a glass mountain, or on the sofa, or on other things scattered on the ground, there was no bloodstain, but a sofa pillow fell near the bedroom door, and the pillow just fell on the location where Yu Jie's body was found, and the pillow was stained with black blood.

Xu Lang carefully avoided the things in the living room, walked to the balcony, and found that the window was open, and the windowsill was wiped very clean, Xu Lang stretched out his hand and touched it, but he didn't feel much dust on the white gloves, Xu Lang walked to the window, stretched out his head and looked out of the window, and found that the bottom of the balcony was just the air conditioning chassis of the people downstairs, and the air conditioning chassis was covered with thick dust, and there were no footprints on it, and Xu Lang raised his head again and looked upstairs, I also saw a large air-conditioning chassis, which was covered with cobwebs and dust, and it seemed that it had not been wiped for a long time.

Xu Lang stood up straight, tried to close the window again, and found that the window could be closed, there was no jerky feeling, and the window was an honest bolt, Xu Lang flicked the latch, and found that there was no problem, it seems that when Li Lei and they investigated the scene before, they came to the conclusion that Jiang Zhengye did not climb in from the window, if he wanted to come in from here, he would either climb up by stepping on the air conditioner downstairs, or coming down from the upstairs, no matter whether he came in from above or from below, he would definitely leave footprints on these two air conditioners, And there is obviously no here, so he did not come in from here.

Xu Lang turned around, looked at the messy and messy living room, and suddenly frowned, Niu Hong and the sofa at home are a little old, and they have been damaged in some edges and corners, this is not the key, the key is that one of these sofas is actually upside down on the floor, and the other is turned on its side and quietly attached to the wall.

Li Lei also came to Xu Lang's side, he glanced at Xu Lang, and found that Xu Lang was looking at these sofas, so he followed Xu Lang's line of sight, and then said; "When we first surveyed the site, this stuff was like that, what's the problem?"

Xu Lang groaned for a while, habitually touched his chin and said, "Don't you think these sofas fall a little strangely?" ”

Li Lei looked at the two sofas again, thought about it, and suddenly, he turned his head, looked at Xu Lang with a shocked face, and said, "It's really strange." ”
