When Xu Lang woke up again, he opened his eyes, the first thing he saw was the white flower ceiling, he turned his head, looked at the window, and found that a ray of sunlight shone into this room through the curtains.

Xu Lang lifted the quilt and sat up from the bed, he exhaled a long breath, looking at the familiar bedroom and the familiar environment, Xu Lang felt as if he had returned from hell.

Since Shu Yue left this time, Xu Lang's mood has not been very stable, although he looks very calm on the surface, but that is just the appearance, during this time, Shu Yue prepared for Xu Lang, Xu Lang has already eaten, of course, these medicines are enough for Xu Lang to eat for three months, provided that Xu Lang eats according to Shu Yue's instructions, but since Xu Lang came back, especially after seeing Xu Qi, he has taken more and more medicine every day, and the number of nightmares at night has increased, Many times, when Xu Lang opened his eyes and woke up, he didn't know whether he was living in a dream or in reality, unless he felt hungry or had a physiological need, Xu Lang would feel that he was living in reality.

Xu Lang did not light a cigarette as before, but got up directly from the bed and went to the bathroom to start washing.

Just as Xu Lang finished washing and getting dressed, the doorbell rang suddenly.

"Ding-dong, ding-dong."

Xu Lang walked to the door, glanced outside from the cat's eye, and found that it was a man wearing courier clothes, the man was holding a courier in his hand, anxiously waiting in front of the door, although Xu Lang was not familiar with this man, but he knew, knowing that he was the little brother who was responsible for delivering express delivery to this community, Xu Lang had seen him in the community many times, so Xu Lang opened the door and looked at the courier brother.

"Your courier, please sign for it." The courier brother handed the package in his hand to Xu Lang.

Xu Lang took the package with a puzzled look and looked at it, except for the delivery address of Xu Lang's house, there was no other information, there was no sender's address, and there was no sender's contact information, Xu Lang couldn't remember that he had bought something online, and he didn't like online shopping very much, Xu Lang looked at the courier, and then looked at the courier brother and asked, "What is this?" ”

The courier brother said with a dumb smile: "I'm just in charge of delivering the courier, as for what's in the courier, I don't know." ”

Xu Lang thought about it and laughed dumbly, too, how could he know, thinking of this, Xu Lang took the pen from the courier brother and signed his name, and after the courier brother tore off the courier order, he took the pen and turned around and went downstairs.

Xu Lang took the courier back home with a puzzled face, closed the door, and came to the living room, he picked up a utility knife from under the coffee table and carefully opened the express box, and after tearing the outside packaging, Xu Lang found that it was a very exquisite box inside, and there was no LOGO on the box, Xu Lang opened the box and found that what was in the box was not anything else, all of them were medicine bottles, and these medicine bottles were all opened by Shu Yue for Xu Lang to eat.

Seeing these medicine bottles, Xu Lang suddenly became excited, he didn't care about those medicine bottles, and rummaged through the box, finally, Xu Lang found a piece of paper, after Xu Lang opened the paper, he was surprised to find that this paper was a blank paper, not a word was written on it, only the stains of tears were still there, Xu Lang looked at the white paper, looked at it for a long time, and the original excitement gradually calmed down, he put away the white paper, and walked into the bedroom with the medicine bottle.

When Xu Lang came out of the bedroom, his mobile phone rang, Xu Lang thought it was a call from Shangguan Jing, and saw that Ye didn't look at the caller ID, so he answered the channel: "Don't rush, I'll go out immediately." ”

"Out of the house? Where are you going? Ning Yanran's voice rang on the other end of the phone.

Xu Lang was stunned for a moment, he put down his mobile phone and looked at the caller ID, it was originally Ning Yanran calling, he put the phone to his ear again, and said, "It's nothing, call me now, is there any new progress in the case?" ”

"Hmmm......"

Ning Yanran was silent on the other end of the phone for a while before saying, "It's okay, it's not clear on the phone, you come to the Public Security Bureau." ”

Hearing Ning Yanran say this, Xu Lang thought that there was something new wrong in Niu Honghe's case, so he didn't ask any more questions on the phone, but said, "I'll be there in a while." ”

After speaking, Xu Lang hung up the phone, then picked up the phone and left the house.

————

When Xu Lang came to the second criminal investigation team, he found that everyone was busy with their own affairs, and most of the people in the office area were not there, Xu Lang didn't feel strange, he didn't see Ning Yanran in the office area, so he went straight to Ning Yanran's office.

The door was closed, Xu Lang knocked symbolically, and without waiting for an answer from inside, he pushed the door and entered.

After Xu Lang entered, he found that Ning Yanran was sitting behind the desk with a somewhat unpleasant face, Xu Lang walked to Ning Yanran and sat down, his eyes first glanced at Ning Yanran, and then glanced down at the desk, Xu Lang found that there was a pile of documents on the desk, Xu Lang retracted his gaze, looked at Ning Yanran and asked, "What's wrong?" What's wrong with you can't say it on the phone? ”

Ning Yanran raised her head, looked at Xu Lang, her expression softened, and said, "The DNA comparison results of Niu Jinglun and Niu Honghe have come out. ”

"Is it Niu Honghe's own child?" Xu Lang asked.

Ning Yanran frowned, picked up an appraisal report from the table, handed it to Xu Lang, and said, "Take a look for yourself." ”

Xu Lang took a look, the result was very obvious, Niu Jinglun was not born to Niu Honghe, and the two of them were not related by blood at all, after Xu Lang read it, he raised his head, looked at Ning Yanran and said: "Since the results have come out, then it would be good to interrogate Niu Honghe." ”

Ning Yanran looked at Xu Lang, and Nunu said, "There is also a DNA identification result below, you can talk about it after you finish reading it." ”

Xu Lang turned a page, only glanced at it, Xu Lang's face changed, he raised his head and looked at Ning Yanran and said, "How is this possible?" ”

"Hey."

Ning Yanran sighed and said, "When I saw this appraisal report, I also thought it was impossible, but the result was very obvious, and I couldn't figure it out." ”

Hearing Ning Yanran say this, Xu Lang lowered his head and looked at the appraisal report again, this is a DNA identification report of Niu Jinglun and the deceased Yu Jie, the report is written very clearly in black and white, the DNA comparison results of Yu Jie and Niu Jinglun are not relatives, and the two are not mother and son at all, so Xu Lang was so surprised when he saw this scene.

Ning Yanran saw that Xu Lang was silent, so she said: "Yesterday, you asked us to compare the DNA of Niu Jinglun and Niu Honghe, I made an improvised decision at that time and decided to do a DNA comparison for Yu Jie, but what I didn't expect was that this result would appear." ”

After Xu Lang saw the DNA comparison results of Niu Jinglun and Niu Honghe, the first thing he thought of was that his previous speculation was not wrong, but when he saw the DNA comparison results of Yu Jie and Niu Jinglun, Xu Lang felt that his previous speculation might be wrong, if Niu Jinglun was not Niu Honghe and Yu Jie's biological son, then Niu Honghe would have sufficient motive to commit the crime, but Niu Jinglun and Yu Jie were not a mother-son relationship, so there was a problem with Niu Honghe's motive for committing the crime and the suspicion of murder. It simply doesn't hold water.

Thinking of this, Xu Lang put down the documents in his hand, looked at Ning Yanran and asked, "Whose child are you Niu Jinglun?" ”

Ning Yanran looked at Xu Lang, and said with a somewhat complicated look: "Say it, you may not believe it, Niu Jinglun is actually Jiang Zhengye's child." ”

“why？” Xu Lang looked at Ning Yanran with a shocked expression.

Ning Yanran nodded and said, "I'm not joking with you, the forensic department compared Jiang Zhengye's DNA with Niu Jinglun's DNA, and it was just just in case, but what I didn't expect was that Jiang Zhengye and Niu Jinglun's DNA actually matched, and I was also very surprised." ”

Hearing Ning Yanran say this, Xu Lang silently took out the cigarette case from his pocket, took out a cigarette and lit it, and fell into deep thought.

Ning Yanran seemed to know that Xu Lang would have this reaction after knowing this result, she stood up, walked to the water dispenser, took two disposable cups, one was full of water, and one was only a little, and then put the cup of half a cup of water on Xu Lang's left hand, and put the cup full of water on Xu Lang's right hand, after doing all this, Ning Yanran walked back to her seat and sat down.

Xu Lang's mind is a little confused now, he needs to smoke a cigarette to calm down.

After Xu Lang lit the cigarette, he only took a puff and didn't smoke it again, letting the cigarette burn silently there.

Originally, at the beginning of this case, it seemed that it was just a murder case caused by burglary, but as the investigation deepened, Ning Yanran and they felt that this case was not so simple, not like a burglary, but like a premeditated homicide case, and Niu Honghe was the most important suspect, but after the results of these two DNA identifications came out, not only Xu Lang was stunned, but Ning Yanran also felt that things were a little bizarre.

If Niu Jinglun was not born to Niu Honghe, but the child born to Yu Jie and other men, Niu Honghe was cuckolded by his wife, and he had a sufficient motive to commit the crime, but the child was not Niu Honghe and Yu Jie's, but the deceased Jiang Zhengye's, which is strange.

First, according to the previous investigation, Niu Honghe and Yu Jie don't know Jiang Zhengye, and there is no intersection at all, Niu Honghe and Yu Jie are both factory workers, and Jiang Zhengye is a habitual thief, and there is no intersection between the two sides at all, so how can Jiang Zhengye's children be in Niu Honghe's house? The child still calls Niu Honghe dad and Yu Jie's mother? And why is the child's surname Niu instead of Jiang?

Second, since the child is Jiang Zhengye's, then, the child was not born to him and Yu Jie, so who is the child's mother? Why is he at Niu Honghe's house?

Third, Jiang Zhengye is Niu Jinglun's biological father, and Niu Hong and the husband and wife are Niu Jinglun's adoptive father and adoptive mother, so why did Yu Jie and Jiang Zhengye die in Niu Honghe's family? In the end, Jiang Zhengye killed Yu Jie, and Niu Honghe killed Jiang Zhengye again? Or did Niu Honghe kill the two of them?

Thinking of this, Xu Lang suddenly remembered the things he found at the murder scene yesterday, and asked: "The things I asked Li Lei to bring back from the murder scene yesterday, did the appraisal results come out?" ”

Ning Yanran was stunned for a moment, then stood up and walked to the door, and said to Li Lei, who was doing things, "Li Lei, you come in." ”

Hearing Ning Yanran call himself, Li Lei hurriedly put down the work in his hand and walked into Ning Yanran's office, when he saw that Xu Lang was also there, he asked suspiciously: "Team Ning, what's wrong?" ”

"Did the results of the identification of the things you brought back from the murder scene yesterday?" Ning Yanran asked.

Li Lei glanced at Xu Lang, and then said, "Just now, the forensic department called and said that the results were out, let me go and get them." ”

"Hurry up and get the results." Ning Yanran said.

Li Lei hurriedly walked out of the office and went to the forensic department.

After a while, Li Lei came back with the appraisal results.

Seeing that Li Lei was back, Xu Lang snatched the document from Li Lei's hand and looked at it, he only turned a few pages, put down the document, and the expression on his face became very strange, Ning Yanran was puzzled, she took the appraisal report from Xu Lang's hand and looked at it.

After reading it, Ning Yanran said with a surprised face: "On the fourth set of toiletries found in Niu Honghe's house, fingerprints and biological samples were collected, and after fingerprint comparison, this set of toiletries belonged to the deceased Jiang Zhengye, and the clothes found in Niu Honghe's second bedroom at home were also Jiang Zhengye's, how is this possible?" ”

Li Lei looked at Xu Lang, then at Ning Yanran, and suddenly, he seemed to remember something, took out an appraisal report and handed it to Ning Yanran and said: "Yesterday we found a footprint under the sofa in the living room of the murder scene. ”

Xu Lang's brows, which were already frowning, became a little tighter after hearing Li Lei say this.

At the scene of the murder, a total of two bodies were found, one of which was the body of Yu Jie, the hostess of the house, and the other body was Jiang Zhengye's, and it was Niu Honghe, the male owner of the family, who came to report and surrendered, but the footprints of the fourth person were found at the scene of the murder, so who is this fourth person? What is the relationship between him and Niu Honghe's family, as well as Jiang Zhengye?

Thinking of this, Xu Lang raised his head and looked at Li Lei and asked, "Did you find other people's fingerprints at the scene, except for the fingerprints of Niu Hong, his family and Jiang Zhengye?" ”

Li Lei also said with a puzzled face: "No, only the fingerprints of Niu Hong, his family and Jiang Zhengye were found at the scene, and no other people's fingerprints were found." ”

"No fingerprints found."

Xu Lang repeated, and then fell into deep thought, if there was a fourth person at the scene when the murder occurred, since he left a footprint at the scene, how could he not leave fingerprints? Could it be that this person was wearing gloves on his hands when he entered the scene? If this is the case, then this person must have a certain sense of anti-reconnaissance, since he has a sense of anti-reconnaissance, he knows that he can't leave fingerprints on the scene, then it is impossible to leave shoe prints, this doesn't make sense at all.

Just when Xu Lang and the three of them fell silent, Zhang Lei suddenly ran into the office in a hurry and said loudly: "We have found out the relationship between Niu Hong and Jiang Zhengye." ”

As soon as Zhang Lei's words came out, Xu Lang and the three of them all looked at Zhang Lei.

Zhang Lei was a little uncomfortable by Xu Lang and them, he scratched his head and said, "What's wrong?" Didn't you just find out their relationship, as for looking at me so nervously? ”

Xu Lang didn't have the patience to listen to Zhang Lei's words, and directly interrupted him and asked, "Come on, what is the relationship between Niu Honghe and Jiang Zhengye?" ”

Zhang Lei was bored, so he said honestly: "After we investigated and visited, we learned this information from Jiang Zhengye when he was in prison by investigating his cellmates. ”

"What kind of information, just say it." Ning Yanran was also anxious.

"Jiang Zhengye's cellmate told me that he also accidentally found out about it when he was chatting with Jiang Zhengye, Jiang Zhengye said that he and a few friends came out of the orphanage, and when he was fooling around outside, he gave birth to a child with one of the girls who came out of the orphanage together, and now this child lives in another family."

"An orphanage? Which orphanage? Xu Lang asked.

"What is the name of the woman who gave birth to Jiang Zhengye?" Li Lei asked.

"Is Jiang Zhengye's child in Niu Honghe's house?" Ning Yanran asked.

Zhang Lei was stunned by Xu Lang and the three of them, he didn't know who to answer first, Xu Lang was his former captain, Ning Yanran was his current captain, and Li Lei was the vice captain, all three of them were Zhang Lei's leaders, Zhang Lei was really embarrassed.

In the end, Zhang Lei thought about it, and answered Xu Lang's question first: "He didn't know which orphanage, and he didn't ask deeply at that time, he cared more about Jiang Zhengye's child and the woman who gave birth to Jiang Zhengye." ”

"What's a woman's name?" Xu Lang asked.

Zhang Lei thought for a while and said, "It seems to be called Yu Huixin." ”

"Then where is this Yu Huixin now?" Ning Yanran asked.

Zhang Lei shook his head and said, "It seems to be dead." ”

"Dead?" Xu Lang and the three of them immediately frowned and looked at Zhang Lei.

Zhang Lei hurriedly waved his hand and said with a wry smile: "Don't look at me like that, it was Jiang Zhengye's cellmate who told me, when he asked about Jiang Zhengye's woman, Jiang Zhengye said that she was dead." ”

Xu Lang pondered for a moment and then asked, "Then does he know whose house Jiang Zhengye's child was stored in when Jiang Zhengye was serving his sentence in prison?" ”

Zhang Lei nodded and said, "I know, it's Niu Honghe's family." ”

"Are you sure?" Xu Lang stood up and asked.

Zhang Lei nodded hurriedly and said, "It's true, it was Jiang Zhengye who told him personally." ”

After hearing this result, Xu Lang and the three of them immediately glanced at each other and looked at each other.
