When Bi Guofeng woke up from the bed at home, the teddy dog next door was barking as always. Bi Guofeng has wanted to knock on the door of the house next door more than once and tell the dog owner about the dog's noise. But because of the face of the neighbors, they never spoke.

Last night, Bi Guofeng dreamed of his mother Zhang Hui again, and in the dream he returned to that familiar and warm home. His father, Bi Weiguo, sat in the middle of the living room with a newspaper, and a noisy dance party was playing on the TV. The chandelier on the ceiling was shining with a clear yellow light, and he could clearly see the water vapor wafting from the kitchen in the light.

In the dream, Bi Guofeng once again ate the dumplings made by his mother, but when he took a bite, there was no taste. Bi Guofeng was accustomed to such dreams, after all, he had not tasted his mother's dumplings for more than 20 years, and that taste had long since disappeared from his memory. But Bi Guofeng still swallowed the dumplings in the bowl into his stomach one by one, and the feeling of his stomach swelling made him feel at ease.

Bi Guofeng felt ridiculously stupid, but it was in a dream, and no one would laugh at him. So, he can do what he likes with peace of mind. But what he didn't understand anyway was why he couldn't control the outcome of every dream.

After eating the dumplings, Bi Guofeng saw his mother wearing the police uniform in his dream, she hugged herself and said in her ear: "Mom will come when she goes, you have to go to bed early." Bi Guofeng didn't dare to agree to this, because he knew that once he nodded, his mother would put her down and leave. Bi Guofeng learned to grit his teeth and not speak in his dreams, thinking that as long as he didn't agree, his mother would not leave. But Zhang Hui still left, no matter what Bi Guofeng did, she just let go of Bi Guofeng gently.

After waking up from a long dream, Bi Guofeng felt that his head was groggy, and the back molars on his right side became more and more painful. It had been twenty-four years since his mother left him, but what happened that night was like yesterday. Bi Guofeng's mind flashed back to Zheng Suwen's reaction when he learned that Zhang Xian was going to be taken away by them last night, the pain when his loved ones left turned out to be the same for everyone.

Today is December 19th, and the investigation into Zhou Xi's case has been launched rapidly, but Bi Guofeng has achieved very little results. Yesterday, under the heavy pressure from above, they had to arrest the only suspect, Zhang Xian, who found Zhou Xi's body. But Bi Guofeng's intuition told him that Zhang Xian would not be the murderer of Zhou Xi.

Today is the day of the second arraignment of the suspect in the nude death case of the model on December 18, and Bi Guofeng quickly washed up and put on his uniform. After the rectification was completed, Bi Guofeng walked out of the door and took out three incense sticks from the incense box, lit them and inserted them into the incense burner in front of his mother's spiritual seat. As usual, he silently muttered about his mother.

"Ah Feng, what was the result of the blind date I arranged for you the day before yesterday." A stern but hoarse voice sounded behind Bi Guofeng, "This time I arranged a very good girl for you, which was introduced by the director of the TV station." ”

Bi Guofeng didn't look back and said: "Dad, don't arrange a blind date for me in the future, I want to go, I will handle my affairs myself." ”

"Handle it yourself? Which of those women you're looking for can see? If it weren't for the girl with a head and a face, you wouldn't think I would have agreed to enter our door! You have to get along with other people, this girl, do you understand? If it doesn't work out this time, you won't have to go back to this home again! ”

Bi Guofeng was stunned, and hurriedly said, "Dad, why do you bother......

Bi Weiguo paused and said, "At eight o'clock tonight, the Christmas Movie Week Prediction Ceremony will start, you can come back early to watch it with me." ”

Bi Guofeng heard the sound of his father turning on the TV with a remote control, and with a "boom", the current passed through the screen, and the dialogue began to sound slowly from low to high, like a curtain above the stage being slowly lifted.

Bi Guofeng looked down at the incense burner with so much ash that it was about to overflow, and then glanced lightly at his father on the sofa. He grabbed the key and squeezed it vigorously, as if he wanted to say something, but after being stunned for a long time, he finally only spit out one sentence: "Got it, Dad." ”

Bi Guofeng rushed out of the house with his head down, he felt that his heart was blocked, since his mother died, his father was less and less like the previous father. Thinking of this, Bi Guofeng shook his head, he got into the cab of the car, started the accelerator and drove in the direction of the police station.

Ten minutes later, Bi Guofeng saw Zhang Xian, the biggest suspect in the 12.18 case, inside and outside the waiting room. But what made Bi Guofeng feel strange was that in addition to him, there were also a cadre of criminal policemen standing there, and there were many fresh faces among them.

Bi Guofeng asked Chang Zhi, who was standing on the side: "Who are these people?" ”

Chang Zhi said with a gloomy face: "Team leader, you are here, this is sent by the top to assist in the investigation, I heard that a similar case has occurred in the Mikamihara District next door, and if necessary, the case may be combined and handled." ”

Bi Guofeng nodded, thinking: If it is not necessary, it is better not to put the leadership of this case in the hands of others. This group of old bones was sent over at this time, and I don't know if I can help.

The veteran police officer who led the Mikamihara District was named Li Hong, who was very experienced in criminal investigation, and when he saw Bi Guofeng, he frowned and said, "You are the person in charge of this case?" ”

"yes." Bi Guofeng nodded.

"Why did you come so late, this is a criminal case, do you take it so seriously?"

"Oh...... I was a little late to check the information last night, sorry. ”

Li Hong asked, "Did you find anything?" ”

"No...... Well, I'm looking into another case. Bi Guofeng said, "It's a private matter." ”

"Do you have a bit of a ...... in doing this?"

Li Honggang wanted to get angry, but was pulled aside by Chang Zhi behind him: "Don't worry, the team leader used his personal time to investigate the case." ”

Li Hong was even more dissatisfied when he heard this: "What kind of private time, now that the murder case is in front of us, where is there any private time." ”

Chang Zhi was also anxious: "The team leader is investigating the Christmas murder case twenty-four years ago. ”

"What does the case from so long ago have to do with him?"

"It was his mother who died in that case."

"Twenty-four years ago...... Li Hong was shocked, and the memory slowly poured into his brain, "You mean Zhang Hui ......"

Chang Zhi nodded: "The team leader has never given up investigating his mother's case, this is a well-known thing in the bureau, don't take it to heart." Although the team leader has an eccentric temper, he is not an unmeasured person. ”

"As a son, I have nothing to say about investigating his mother's case, it's just right." Li Hong's tone had softened at this time, and he walked up to Bi Guofeng and said, "I didn't know the situation just now, I'm really sorry, but I'll just talk about the matter, you investigate other cases and investigate other cases, don't affect the murder case in front of you, after all, we are the people's police, and we are responsible for all the people." ”

"I'm measured." Bi Guofeng said lightly.

Li Hong lit a cigarette: "The person you arrested this time is a little young, and several of the cases on our side are old cases from more than ten years ago, so I don't think it is likely to be a co-defendant." Perhaps, this cooperation ended soon. ”

Bi Guofeng glanced at Li Hong strangely: "I haven't skimmed the eight characters yet, let's ask this first." ”

"Yes, we're here to find out. As mentioned above, those cases are like thorns in the eye, thorns in the flesh, and it is uncomfortable if you don't pull them out. Li Hong took a sharp puff of his cigarette.

Bi Guofeng secretly thought in his heart: Fortunately, they didn't want to take the initiative to intervene. The instructions given so far have been limited to assistance. But Bi Guofeng knew in his heart that judging from the age of these people, it can be said that the top attaches great importance to this case. If you can't make progress in this case in a short period of time, it will be a matter of time before these "old-timers" intervene.

After smoking a cigarette, Bi Guofeng asked the others for their consent, and then asked Chang Zhi to take Zhang Xian into the interrogation room.

"Did you sleep well in there?" Bi Guofeng put down a glass of water on the table and said to Zhang Xian in front of him, intentionally or unintentionally.

"Is it going to be okay? It's so uncomfortable for me. Zhou Xi really didn't kill me, I was just the discoverer of the corpse. Unlucky, if I had known that things would turn out like this, I shouldn't have gone to her. Zhang Xian drank the water in one go.

Bi Guofeng was furious when he heard this: "As a man, shouldn't you say, 'If I knew this, I should have gone to her earlier'?" If you had gone to find Zhou Xi earlier, maybe she wouldn't have died. ”

"You mean, I killed my girlfriend?"

Bi Guofeng remained silent, he touched his nose and secretly observed Zhang Xian's expression. Unlike when he was just arrested the day before yesterday, Zhang Xian had obviously calmed down, and even dared to speak to himself like this. However, Zhang Xian's eyes never dared to look at him for more than a second, if there was really no ghost in his heart, why should he be so cringe?

After a moment of silence, Bi Guofeng continued to ask: "Where were you between 7 p.m. and 9 p.m. on December 18?" And with whom? What are you doing? ”

"Officer, how many times have I said it, I went to drink with my friend Liu Hewen after 19 o'clock that night. It wasn't until about 8 p.m., when the wine was almost drunk, that I wanted to go to my girlfriend's place, only to find her body. I swear, I'm telling the truth. Zhang Xian comically raised three fingers.

"How many keys do you have to your girlfriend's house?" Bi Guofeng took the paper cup that was drunk by Zhang Xian and squeezed it into a ball vigorously.

"There must be several." Zhang Xian looked at the flattened paper cup and swallowed.

"Then your girlfriend didn't give you a handful?"

"I didn't ...... No. Zhang Xian felt a little uncomfortable, "Do you still suspect that I killed Zhou Xi?" "Officer, I've said it many times, I drank a lot of alcohol that day, I had a terrible headache, and I basically lost the ability to control my body, which my friend Liu Hewen can prove."

"I've seen a lot of cases of drunken murders, and it's useless for you to tell me about this."

Zhang Xian pouted noncommittally: "If you don't believe it, just ask my friend." ”

mentioned Liu Hewen again, and Bi Guofeng's heart was a little nervous. Judging from the confessions brought back by his subordinates, Liu Hewen claimed that he and Zhang Xian had been drinking together between 8 p.m. and 9 p.m. on December 18. But the place to drink is near the Lianhe Bridge, which is a blind spot covered by surveillance cameras. Although it is not ruled out that Liu Hewen may commit perjury, doesn't he deliberately favor the side where Zhang Xian is the murderer? In the final analysis, Zhang Xian's face is too disgusting. Bi Guofeng felt that the more he looked at the handsome face in front of him, the more hateful he felt.

Bi Guofeng asked Chang Zhi, who recorded the confession, to stop writing first, and then left the interrogation room alone. He stood in the corridor thinking about what to do next, this Liu Hewen obviously couldn't provide Zhang Xian's alibi when Zhou Xi was killed, and Zhang Xian himself should know this. Zhang Xianming used Liu Hewen as his shield, he must not dwell on this issue for too long, otherwise the rhythm of the interrogation is likely to be controlled by the other party. But now the question is, if Zhang Xian is not the murderer, why didn't he clear up the relationship as soon as possible, but kept saying some ambiguous things? Bi Guofeng felt more and more that things were not as simple as he imagined.

When Li Hong saw him coming out of the interrogation room, he hurriedly ran over and asked, "What's going on?" Is he the person who found the body or said to be a suspect? ”

"Both." Bi Guofeng raised his eyes and glanced at Li Hong and said, "Do you dare to believe it?" The day before yesterday, after he found the body, he reported it to the police, and he fell asleep at the scene. ”

"Ridiculous! Wasn't that the one who died his girlfriend? ”

"That's what we thought, it's not someone else, it's his girlfriend. At that time, we also subconsciously thought that he was the murderer. ”

Li Hong shook his head: "It's really wolf-hearted, how could this woman fall in love with such a person?" ”

"To be honest, Zhang Xian, this kid, I didn't feel right from the beginning. Although he was drunk, since he could still realize that he called the police, it means that he was not drunk enough to be unconscious at that time. ”

Li Hong sneered: "I feel that this person seems to be deliberately leading our police to suspect him." To be honest, it's the first time I've seen someone who has been a criminal police officer for so many years, and I won't avoid suspicion. ”

Bi Guofeng pondered for a moment, but he couldn't think of a reason: "I feel that I still have to figure it out first, this old fritter is not easy to say." ”

"Hou Shengzi, can you do it? I don't think you're very experienced in asking for confessions, do you want me to ......," Li Hong asked with a frown.

Bi Guofeng was about to answer, but saw Kong De, the leader of another team in the bureau, walking towards them with his subordinates. As soon as he came to them, he first exchanged a few words with Li Hong and his entourage, and the meeting was almost there. Then he handed out a few cigarettes to a few colleagues, but when he sent them to Bi Guofeng, a pack of cigarettes had just been distributed. Bi Guofeng glanced at Kong De, and didn't think it was a big deal, so he took a cigarette from his pocket and smoked it.

After a cigarette is down, everyone extinguishes the cigarette butt in the ashtray. Kong De opened his mouth and said: "Guofeng, what's the situation, the upper authorities have set a time limit, saying that they will let you solve the case within half a month." I don't think this kid is difficult to deal with, if you can't do it, just leave it to these seniors to ask, they are all decades of veteran criminal police. ”

Bi Guofeng gritted his teeth, the man named pot-bellied poop in front of him was at the same level as him, although he didn't look up and look down on weekdays, but there was no friendship between them. At this time, he obviously came to find fault, so he said: "I can handle this little thing myself, if it really doesn't work, it's not too late to go back then." After saying that, he threw the cigarette butt to the ground and stepped on it.

When Bi Guofeng returned to the interrogation room, he had already thought of a new strategy against Zhang Xian, and this time he decided to slow down the pace of the questioning. Bi Guofeng took out a box of cigarettes from his pocket and lit one for himself. He stretched out his hand and shook it towards Chang Zhi, signaling him to come too, but Chang Zhi didn't answer. Then Bi Guofeng intentionally or unintentionally threw the cigarette case on the table, and he lay in the chair and smoked heavily, and the small room soon became cloudy. Zhang Xian swallowed his saliva, his eyes kept staring at the box of cigarettes, but he never had the courage to reach for it.

"Zhang Xian, do you know how many years the crime of intentional homicide is usually sentenced?" Bi Guofeng squinted his eyes, intoxicated by the enjoyment of smoking.

"Ah...... Yes? ”

"You said that you are still so young, if you go in once, this stain will be with you for a lifetime, don't you say?" Bi Guofeng stabbed Chang Zhi beside him.

Chang Zhi smiled: "These files will affect your loan, work or even marriage, you have to think about it." ”

Zhang Xian shrunk his neck: "I don't understand what you mean." ”

"Don't understand?" Bi Guofeng said, "Then you don't understand how hard it is for your parents to give birth to you and raise you for so many years." What would they do if you did? As far as I know, you are an only child, and you have no brothers or sisters. ”

Zhang Xian lowered his head, his hands kept peeling his nails under the table, and fell into a long silence.

Bi Guofeng scratched his head irritably, and he began to hate Zhang Xian's pretentious face. The other party is not the kind of person who will bow his head when he sees the police, and Zhang Xian is obviously replacing his answer with feigned fear. This kind of trick to delay the progress of interrogation, Bi Guofeng has long been tired of seeing it after so many years as a police officer.

"If there are accomplices, there is also meritorious service if you take the initiative to provide it. Especially accomplices, after counting it back and forth, you don't have to stay in it for long to get out, you should have learned this addition and subtraction" Bi Guofeng pulled out a cigarette and threw it over with a lighter.

Zhang Xian smiled and picked up the cigarette and lighter and was about to light it, but when he heard Bi Guofeng's words, he immediately stopped again: "This ...... Officer, where does this begin? ”

"Don't fucking pretend, if you have anything to explain, you don't have much time left in detention, so you don't have to worry about our brother taking you in and out, aren't you tired?" Bi Guofeng slammed the table and roared: "You didn't calculate anything, after killing Zhou Xi, you were seen when you escaped from Jinjing Garden." ”

Chang Zhi saw Bi Guofeng so out of shape, for fear that he would make some drastic moves, so he quickly grabbed Bi Guofeng's shoulder.

"Am I being seen? That's impossible. I went to the scene after I drank that day, but I went to find my girlfriend, not kill my girlfriend. Zhang Xian took the cigarette butt out of his mouth and put it back on the table along with the lighter.

"It's really a hard bone, let the witnesses come and recognize the person." Bi Guofeng waved his hand and asked people to take Zhang Xian out.

"Brother Feng, did he really do it?" Chang Zhi lowered his voice and asked Bi Guofeng.

"I don't know if it's him, but look at his virtue, it's not a good thing at first glance, let the witnesses recognize the person first. Some people are like this, they don't cry when they don't see the coffin. ”

As soon as Bi Guofeng gave the order, Li Hong leaned over: "I haven't heard that you still have eyewitnesses, if it goes well later, let's ask?" ”

"Yes, if it really goes well......" Bi Guofeng somehow had no confidence in his heart.

Not long after, a short man was brought to Bi Guofeng. Bi Guofeng looked at him a little surprised: This is the eyewitness?

The eyewitness glared at Bi Guofeng without showing weakness and said, "What do you see? Didn't you call me to recognize people? Let's get started, I have something to do. ”

Bi Guofeng sighed, and had to ask Chang Zhi to quickly bring the seven people who were about to be identified into the opposite room. Unexpectedly, at this time, the eyewitness suddenly covered his face and hid behind Bi Guofeng, and said while dodging: "Officer, they all saw me standing behind the glass, what if they come out and retaliate against me?" ”

"No, it's not glass, it's a two-way mirror. We can see them, but they can't see us, so you can identify them. Bi Guofeng patiently explained, "You now take a closer look to see which one is the suspicious person you saw that night." If you need anything, we can meet your needs, such as looking at the suspect's back, side, or even wanting to listen to their voice. ”

As soon as the eyewitness heard this, he walked out from behind Bi Guofeng, and he rubbed his hands comically: "Really? You're acting like a movie. Then you make them turn around, I want to see the back. ”

Bi Guofeng opened the door and greeted the auxiliary police outside: "Let them turn around." The auxiliary police officer agreed, and passed the order over.

The eyewitness stared at the backs of several people for a moment, then stretched out his hand and pointed to the second person on his left and said, "It seems to be such a person." ”

"Like? You have to be sure, it's very important for our police to solve the problem. Bi Guofeng was clearly dissatisfied with the eyewitness's statement.

The eyewitness thought for a moment and then said, "You are stumped on me, it was already dark, and the street lights in the neighborhood were dim, and I could roughly see my back." I think it's this one, the second one on the left. Then his tone suddenly became extremely affirmative.

Bi Guofeng was depressed in his heart, but he had nowhere to attack: "Okay, Chang Zhi, take him out, there's nothing wrong here." "Zhang Xian, the last sturdy man standing among the 7 people, and the fat man who is in second place have no similarity at all, no matter what, you can't be mistaken, it seems that the last clue that can get in touch with Zhang Xian in this case has also failed.

That night, Zhang Xian was interrogated several rounds by Li Hong and his party in a different way, but in the end he did not get anything different from Bi Guofeng. Bi Guofeng wanted to investigate the size and characteristics of the person identified by eyewitnesses, but the above did not agree. The testimony of that eyewitness was clearly not very credible, and the scope of the investigation was ridiculously large, and it was difficult to carry out. Bi Guofeng's investigation has reached an impasse for a while, while Zhang Xian's detention has come to an end.

When he was about to get off work, Bi Guofeng remembered his father's advice. Although the work in front of him cannot make progress for a while, he can choose to leave work at the specified time, but Bi Guofeng would rather continue to stay and work overtime to do some boring investigation work than go home to watch those boring TV shows with his father.

His father, who is also a police officer, worked as a public relations officer in the police force before retiring and worked with television for more than 15 years. Until he retired, he was still inseparable from everything related to TV, and even the blind date he introduced to him was closely related to it. But this does not mean that Bi Guofeng will also like things related to TV, he is still a person who regards criminal investigation work as his responsibility in his bones. This is too different from his father.

"Team leader, I'll get off work first. Aren't you ready to go? Chang Zhi didn't know when he appeared behind Bi Guofeng.

"Wait a minute, have you checked Zhang Xian's computer and the mobile phone he carried?"

"I've checked it, and there's nothing out of the ordinary. The last contact with Zhou Xi was the day before the crime, and there was nothing special in the content, it was all the words that couples often said. ”

"Okay, you can print it out tomorrow, I'm going to read it. In addition, Zhou Xi's mobile phone and computer also made the technical team step up, and I want all the mobile phone communication records except for her and Zhang Xian's chat. There are also all the software used on Zhou Xi's mobile phone, and the accounts that have been logged in, I also want to know. I still don't believe it, this case is really blocked here. Bi Guofeng rubbed his eyes and said, "You get off work first, I still have some work to do." ”

Chang Zhi glanced at Bi Guofeng's computer screen, which was playing surveillance footage of several streets near Zhang Xian's house, so he asked: "Isn't Zhang Xian's line broken?" The person identified by the eyewitness is very different from Zhang Xian, and you can see that those colleagues also have no problem with him, so we don't have to keep an eye on him. ”

"Where can the murder case tolerate a little slackness, the time limit has been set up, and it is ......" Bi Guofeng paused, "Forget it, you go back first, I'll call you if you have something." ”

Chang Zhi's heart sank, he understood the general situation, and he didn't ask any more. He said yes, then took the coat from the coat rack and left.

In the time that followed, Bi Guofeng watched the surveillance video more than a dozen times, but still found nothing. He glanced at the clock on the wall, and it was just past 7 o'clock. Bi Guofeng picked up his mobile phone and thought about whether to call his father, but after hesitating for a long time, he finally gave up.

Bi Guofeng looked at the time that was difficult to kill, and somehow, he remembered the words that his father said to him in the morning. Over the years, there have been hundreds of blind dates of all sizes under the arrangement of my father, but this is the first time that I have paid so much attention to it this time. Bi Guofeng didn't know what reason his father called Cen Min a good girl. In addition to the reason that his father has always emphasized that the other party is the director of the TV station and asked someone to introduce him, whether it is in appearance or personality, he does not think that Cen Min is a person worthy of his liking.

Bi Guofeng is a stubborn person, as long as it is something he believes in, the nine cows can't pull it back. In the same way, what he doesn't like, no one can force him to do. Bi Guofeng lay in a chair, scratching his back with a ballpoint pen, thinking about how to perfunctory the matter. But after he left a mobile phone number for Cen Min that day, the other party never contacted him again. Thinking of this, Bi Guofeng is really a head and two big.

For the sake of today's plan, he had to hope that there would be Cen Min's personal file in the bureau's digital archive. Although using the resources of the Public Security Bureau to investigate others privately is a violation of the law, Bi Weiguo has already given him an ultimatum this time, if it is not really perfunctory, he will not choose to take risks. After all, he logged in with his own personal IP, and all traces left behind would be recorded on the server. If it is known by the superiors, it will be punished at the least, and at worst, it will be expelled from the police.

Soon, the database quickly called up a series of files, and Bi Guofeng copied down the mobile phone number registered on the file that he didn't know what year and month. Then, Bi Guofeng boredly flipped through a few pages of Cen Min's personal information. We have all the information from the school you attended, to the transfer of your family register, to the payment of taxes, and the receipt of benefits. But what made Bi Guofeng feel strange was that the next few pages of the file were encrypted, and he couldn't view them with his own permission.

"Bell ......" At this moment, Bi Guofeng screened through Cen Min's hometown and tried to match information horizontally, when suddenly a rapid phone ringtone interrupted him.

"Hello? Ah Feng, you come down, I have a new discovery. "The phone was automatically connected, and it was an internal line in the bureau.

Bi Guofeng's heart moved when he heard the news, and he quickly put down the search work at hand, then turned off the computer and heating, and walked towards the elevator with his coat. The call was from the underground dissection room. If what is said on the other end of the phone is true, it means that there must be new progress in Zhou Xi's case this time.

A few minutes later, Bi Guofeng met the bureau's forensic doctors Liu Lujin and Zhou Xi in the underground dissection room. Liu Lujin had the same straight face as Bi Guofeng in the past when he saw him, and he couldn't see any expression. Many times, when Bi Guofeng saw him in the dissection room, it was like seeing a walking zombie. The action is mechanical, and the expression is indifferent, as if he doesn't want to have anything to do with this world. And Zhou Xi was lying naked on the dissecting table. The flesh on the belly hung on either side of the body like two open doors.

"Ah Feng, have you looked in the mirror today?" Liu Lujin asked.

"I didn't ...... What's wrong? Bi Guofeng was stunned.

"Your face is ugly, and you've stayed up late again?"

"Oh...... yes. ”

"It's been so long since your mother's case, and it really can't be found in my opinion, so why don't you ......"

"How do you know I must be staying up late for my mother's case?" Bi Guofeng does not like others to interfere with his freedom outside of working hours.

"Hehe, forget it, when I didn't say it. Look at her first, this corpse is not simple. Liu Lujin pointed to Zhou Xi on the dissecting table.

"Any new clues?" Bi Guofeng asked while putting on a mask and gloves.

"Well, I just felt that I hadn't looked carefully at some places, so I invited her out again and inspected her again." Liu Lujin turned on the TV on the wall, "You watch it first, tell me what you think, and see if we want to go together." ”

Bi Guofeng was a little surprised, he quickly lowered his head and began to examine it carefully. A few minutes later, Bi Guofeng made a new discovery.

"Professor Liu, there seems to be something wrong with the bruises on the victim's neck, and there don't seem to be so many marks in the test report during the initial inspection."

"Uh-huh, uh-huh......"

"Professor Liu?" Bi Guofeng turned his head and saw that Liu Lu was watching the entertainment news on TV intently, and he didn't know if what he just said was heard.

"Ah Feng, have you heard of Sang Qing?" Liu Lujin asked.

"I don't know, who is it?" Bi Guofeng was a little puzzled.

"You look at what the news says, tomorrow on the first day of Christmas Movie Week, her new movie will be developed, what is it called "Winter Sonata"."

Bi Guofeng wrinkled his nose, but did not show obvious disgust: "I don't know much about the new movies now, but I think they are alternative clowns raised in modern society, and sometimes they can't tell the truth from the fake when they act." ”

"Isn't it enough for us to tell the truth from the fake?" Liu Lujin said, "Come and tell me, what have you discovered?" ”

We can tell clearly, Bi Guofeng couldn't help but laugh when he thought of his father's current appearance. He carefully washed his gloves under the faucet, and then returned to the autopsy table: "Zhou Xi's bruises on his neck are much more than I saw in the photos in the autopsy report, what do you think is going on?" ”

Liu Lujin nodded, and he pointed to the location of Zhou Xi's neck: "The cause of the victim's death was basically determined when we found the bruises on her neck. The murderer's strength was great, so that the location of the bruises was very concentrated. But today, no...... To be precise, the bruises on the victim's neck began to increase one day after the initial examination, until I found them today. Most of these bruises are shallow and difficult to spot if you don't look closely. ”

"Why is that? There should be no chronological timing of the appearance of bruises on the body of the deceased. And you can see that these bruises are all leaf-like shapes, which are also very different from other bruises. ”

"Not necessarily, the human body is a strange and complex system. When a person is alive, the flow of blood causes bruises to occur very quickly. But as soon as the organs stop working and the blood flow stops, the appearance of bruises is delayed, as we see today. Liu Lujin explained.

"You're saying that these new bruises were left after the death of the deceased." Bi Guofeng recalled that in the cases he had handled in the past, some murderers would indeed further injure the corpse in order to determine whether the victim was really dead, but the bruises on Zhou's body were so subtle that it was not like for this purpose.

"Don't guess yet, the psychological portrait of the murderer by the expert group has come out, you say come and listen to it, and I will help you analyze it." Liu Lujin saw Bi Guofeng's doubts.

"The opinion given by the experts is: the murderer was about 30 to 40 years old, male, able-bodied, sexually dysfunctional. Professor Liu, can this help analyze the causes of bruises? ”

Liu Lujin let out a cold snort when he heard Bi Guofeng read the last item, "Sexual dysfunction? Monkey business. ”

Bi Guofeng was stunned: "Professor, I thought we had reached an agreement on this point," Bi Guofeng's heart sank when he heard this, "We preliminarily speculate that the murderer killed in passion because of sexual dysfunction caused the victim to ridicule and even insult him." Removing and taking away the victim's clothing is a 'shame-covering' response to cover up his physical defects. Moreover, many people with sexual dysfunction do not have a physiological response to the body of the opposite sex, but they do have a specific object. I think that the clothes that were taken away are most likely kept by the murderer as a tool to arouse his sexual desire. Is there anything new in your attempt to disprove this view? ”

"Just listen to me. During the inquest at the scene, we found that the victim's excrement was scattered everywhere and the shape was out of order. It is not difficult to determine that this was caused by the murderer when he took off his clothes after killing the victim. There is nothing to argue at this point, the victim must have been stripped of his clothes after death. But from the examination of the victim's genitals, it is clear that there were no traces of sexual activity before she was killed. In this way, there are two situations: the murderer and the victim did not have time to have sex, and the murderer did not have the ability to have sex with him. Liu Lujin said, "It is indeed possible for you to speculate that the murderer is a person with sexual dysfunction, but have you ever thought that the evidence we have now cannot prove whether the murderer and the victim have had foreplay." If the two had foreplay, then the murderer was 'doing what he knew he couldn't do', and as a result, he had a motive for killing because of sexual dysfunction. But if the two didn't even do foreplay, then we can't be sure that the killer killed because of a 'sexual' dispute.

"Foreplay?" Bi Guofeng was a little uncomfortable when he heard this word, "But the deceased died in the bed at his own home, if the two of them didn't do that, why did they go to the bed?" ”

A subtle smile flashed at the corner of Liu Lujin's mouth: "It's good that the victim died naked in the bed at home, but I didn't find other people's bodily fluids from her body, and in the absence of new evidence, let's not make hasty judgments for the time being." ”

"That's just as well." Bi Guofeng crossed his arms and fell into deep thought.

"By the way, have you ever heard me talk to you about a case before?" Liu Lujin seemed to suddenly think of something.

"There are more cases you have told me, I don't remember which one."

"Oh, that's right." Liu Lujin paused and said, "Not long after I became a forensic doctor, I encountered a case. The killer hung the victim naked from a tree, and wrote two huge words on his back with a carbon pen - 'lowly'. By the time the body was transported to the laboratory, there had already been a giant view, and it took me a lot of work to test the body, but I still found body fluids that did not belong to the deceased. The police then quickly took control of several men who had an emotional dispute with the deceased, and one of the men's DNA matched the semen found in the deceased's body, but the suspect later provided a perfect alibi. The case was at a loss for everyone, and it was almost an unsolved case at the time. ”

"What happened then?"

"Later, a new intern reminded me." "He said that even if bodily fluids were found in the body that did not belong to her, we could not necessarily conclude that the murder was caused by a 'sexual' dispute." Wouldn't it be preconceived to place the suspect among the victim's close friends of the opposite sex? It occurred to me that murderers can confuse our police judgment in various ways when killing victims, and 'sex' is one of them. ”

Bi Guofeng had never heard Liu Lujin talk about this case, and he couldn't help but be fascinated: "Then did you catch the murderer later?" ”

"Of course, of course we caught him, you would never have thought that the murderer would be the victim's cousin who lives in the same village. And the murderer's motive for killing is sad enough, he was ridiculed by the victim with a good relationship with the opposite sex because he couldn't find a girlfriend, and finally held a grudge, so he killed the victim. And the victim did have a relationship with the suspect I mentioned before he was killed. None of us thought that this would invisibly affect the judgment of our police, and it can be said that it was a mistake and a thousand miles wrong. ”

"This ...... The case you mentioned does have something to refer to. Since there will be subjective and objective factors that will disrupt our investigation when a murder occurs, how should we view Zhou Xi's case? After all, we don't have much evidence now. ”

Liu Lujin was stunned: "The lack of evidence does not mean that you can reason indiscriminately, some things cannot be taken for granted." Fortunately, we now have new and reliable evidence. ”

"New evidence? Ah......" Bi Guofeng clapped his hands and said, "Why did I forget this, you mean these new bruises?" But I still can't make the connection between these bruises and the murderer's motive for killing......"

Liu Lujin looked at Bi Guofeng curiously: "Heh, Ah Feng, how long have you not been in love?" ”

"Huh?" Bi Guofeng's face flushed, and he didn't know how to answer.

"It's a kiss mark, haven't you seen it yet? You've never been with a girl...... That's it? Liu Lujin lowered his voice when he said this, "How many times has your father introduced you to blind dates, but it didn't work out?" ”

"Professor Liu, you don't want to open any pot." Bi Guofeng didn't know why Liu Lujin was involved in this matter again, and suddenly became very impatient.

Liu Lujin looked at Bi Guofeng dissatisfiedly and said: "Ah Feng, don't keep working against your father, he is also for your good, you are not the only one who suffered from your mother's incident back then, and your father is also very painful." Now that you're at this age, you should be able to understand him, right? And ......"

"Professor Liu, if there are any clues in this case, tell me quickly, or I'll go back." Bi Guofeng looked at Liu Lujin coldly, completely ignoring the kindness in his words.

"Okay, okay, I don't care about you, you can solve your own business." Liu Lujin waved his hand, "Then again, what do you think of these kiss marks on the victim's neck." ”

"Judging by the time when these kiss marks appeared, it was caused after the victim's death. But why did the murderer kiss the neck of a corpse? ”

Liu Lujin twisted his stiff neck, and said while packing up the surgical tools at hand: "This has to be linked to some other clues to analyze, when I was dissecting the victim, I found home-brewed plum wine, chocolate and an antiemetic drug called diphenhydramine in her stomach." But at the scene of the murder, except for plum wine, diphenhydramine and chocolate were gone, apparently taken away by the murderer and his clothes. We can understand the first two things, but what is the reason why Zhou Xi has to take antiemetics before meeting the murderer? Diphenhydramine is used in very few places, judging from the medical records of Zhou Xi you brought, she has not been ill recently, the use of this antiemetic drug is really suspicious, you have to check it out about this drug. ”

"Okay, I'll make a note of it."

"Well...... Liu Lujin sighed, "After killing the victim, the murderer also kissed her neck fiercely. It doesn't matter if the murderer acts in anger because he didn't succeed, or if he loses his mind. This has already reflected the extreme emotional instability of the murderer. What worries me the most now is that this murderer may have a perverted mentality, and he is also a thoughtful person. Not only did he not flee in a hurry after the killing, but stayed at the scene for a long time, cleaning up the drug packaging box and chocolate that may have left fingerprints, and then left a kiss mark on Zhou Xi's neck. ”

"Professor Liu, do you think that the murderer has an antisocialpersonalitydisorde-type personality?"

"I can't rule out this possibility, I heard that when the victim's body was found, her clothes were not found, right?"

"That's right, I haven't asked you about this issue, why did the murderer take the victim's clothes? Is it because the existence of that dress would reveal the identity of the murderer? Like diphenhydramine and chocolate that disappeared from the scene? ”

Liu Lujin frowned: "This is not easy to judge, of course, your speculation is not necessarily impossible." Personally, I suspect that the killer may have taken the victim's clothes for the purpose of keeping the 'trophies'. ”

"Spoils?" Bi Guofeng was a little surprised when he heard this word.

"Yes, you just asked me if the killer had an antisocialpersonalitydisorde-type personality. Of course, we can't say for sure yet,......" Liu Lujin said after a pause, "If he has such a tendency, then taking away the victim's personal belongings is most likely his purpose is to humiliate the victim, which is a typical example of antisocialpersonalitydisorde-type personality." People like this are often not ashamed of their deviant behavior, but are likely to be unusually proud. Killing is just a means of satisfying their self-values, and if you don't catch him soon, and wait until his murderous pleasure wears off, he will commit a second crime sooner or later. ”

Continuing to commit crimes? When Bi Guofeng heard the news, he felt a tingling feeling in his heart: "Professor Liu, do you say that Zhang Xian is like that?" ”

Liu Lujin said: "I can't say for sure. Although the evidence is not enough to prove that Zhang Xian is the murderer, he is undoubtedly the most suspected. ”

"Doesn't that mean you didn't say that?" Bi Guofeng muttered softly.

Liu Lujin was noncommittal when he heard this: "Let's stop here today, let's go." Liu Lujin pushed Zhou Xi's body back to the corpse cabinet, then turned off the light, and exited the laboratory with Bi Guofeng.

The two walked into the elevator in silence, and at this time Liu Lujin seemed to remember something, he pushed Bi Guofeng and asked, "What TV show has your dad been obsessed with recently, I haven't seen him play chess with me for a long time." ”

"He's ......" Bi Guofeng was very impatient when he heard Liu Lujin mention his father.

"Although you don't like to listen to it, I still want to say that you have time to spend more time with him. How lonely is a person to stay at home and watch TV? It's not hard to understand. Family, always be considerate of each other. ”

Bi Guofeng was noncommittal to Liu Lujin's words, and said in his heart: If you knew that I was threatened, and if I didn't associate with the girl my father said I would be kicked out of the house, I don't know if I would say that?

Liu Lujin looked at Bi Guofeng's reluctant expression, and he was helpless, he changed the topic and asked: "Guofeng, are you still investigating your mother's case?" ”

"Check, as long as the murderer is not caught, I will continue to investigate. It's just that the time dragged on too long, and it became more and more difficult. ”

"Well......" Liu Lujin sighed, "In my opinion, it's better to forget it." ”

"Why?"

"Some truths don't have to be revealed. After so many years, even the wound has grown new flesh, and the scab has long since fallen off, so why bother thinking about that scar? ”

"Don't talk about it, my wounds have never healed." Bi Guofeng looked at Liu Lujin seriously, and his scorching gaze was almost exactly the same as when he was assigned to the bureau after graduating from the police academy.

Liu Lu was speechless for a while, and he silently withdrew his gaze: "Okay, my persuasion is also in vain, whatever you want." ”

In the end, after smoking a cigarette in silence in the police compound, the two broke up in the moonlight. Bi Guofeng offered to drive Liu Lujin, but Liu Lujin unexpectedly did not agree. Bi Guofeng knew Liu Lujin's temper, so he didn't insist, and then drove back home by himself. As soon as he entered the house, Bi Guofeng saw Bi Weiguo's head leaning on the sofa, looking no different from when he went out. When Bi Guofeng saw that he was back, his father did not greet him, thinking that he was asleep, so he wanted to wake him up and let him go into the back room to sleep.

"You're back?" Before Bi Guofeng's hand touched Bi Weiguo, Bi Weiguo suddenly spoke, "Say eight o'clock, why didn't you come back now, fortunately, I recorded the show." ”

Bi Guofeng looked at Bi Weiguo's appearance and shook his head, thinking: It's rare to accompany you to see it once, the last time. Bi Guofeng touched his cheek, and somehow, the tooth suddenly became less painful.
