The news of the water tank in the apartment quickly spread. A bunch of reporters who smelled the smell gathered outside the apartment. Everyone who entered or left the apartment was dragged into an interview. Whether they knew it or not, they had to ask first. With such a mentality, the reporters finally caught one of the residents who knew about it, and that resident also had nothing to say.

So the news that the corpse is suspected to be Tangtang spread overwhelmingly again, and the never-ending crusade on the Internet has intensified. The corpse was successfully transported away earlier, and the remaining people can only wait to be caught by the cameras and microphones. Siege.

Yu Shi's team was still observing the scene on the roof, and they had no intention of leaving now.

"Look at the surveillance in the apartment first." Yu Shi said.

If you want to watch the surveillance, you have to go to the guard room, but there are many people crowded there. The guard room is currently occupied by a young guy, who seems to have just joined the job, staying in the guard room with a face of bewilderment, and the windows are closed.

Yu Shi asked Li Yu to deal with the reporters, and when the reporters all rushed in front of Li Yu in the distance, Yu Shi and Baa Baa went around and entered the guard room from the back, and checked the surveillance under the young man's operation.

"Look at the monitoring from [-]:[-] am to [-]:[-] pm on Tuesday."

Meaaa helped the guy turn on the surveillance during that time period, and checked the apartment before and after, but he didn't find out how Chen Guangxuan entered the apartment, no matter the front door or the back door, not to mention that there are not many residents in this apartment, Residents can be seen coming in and out at every time period. According to the time of Chen Guangxuan's crime, it is impossible for him to quietly enter the roof of the apartment building with the corpse and throw it into the water tank, and he can use other more secretive methods. method, not so much effort.

"Continue to look down first." Yu Shi always felt that something was wrong.

"I can only see it at night. At about eight o'clock on Tuesday night, the mouse bit the wire, and the surveillance of the whole apartment didn't capture it. It was only called in the next morning to fix it." Uncle Zheng also returned to the guard room at this time.

"How do you know that it was bitten by a mouse and not man-made?" Baa-baa asked back.

"With tooth marks, the rat was so stupid that it electrocuted itself to death."

Uncle Zheng recalled that when he saw that mouse, his hair was burnt and stiff.

"Baa baa, copy the monitoring of the last two weeks and take it back." After Yu Shi ordered, he said he had a place to go and left first.

Since Xiang Ling set off to go to the north, Tang Kui was asked to say some information that didn't sound very useful after squatting, ambush, threatening and not being lured but almost seduced by beauty.

Tang Kui has a good colleague in the head office. Since Tang Kui was transferred to the North Branch because of his failure to speak, the two have been in continuous contact. Tang Kui can occasionally hear what happened in the headquarters. , including the recent leak of internal information, he also knows.

But there was only news about Xiangyang, but the other party didn't mention a word, and only asked Tang Kui to wait for the matter to pass, and would find a way to get Tang Kui back to the headquarters later.

Although no one mentioned it, Tang Kui felt that the headquarters did use some methods to make Xiang Yang lose money, so as to achieve the purpose of the acquisition.

"Before Xiangyang, was there a similar situation?"

"I don't know about this. I have heard from retired old employees that when Nanshan was established in the early days, before its name was established in the pharmaceutical field, the first thing they did was to use the name of charity. , attack water sources in some remote mountainous areas, and then launch their own drugs to dominate the market."

"But will the newly established company have such a large financial resources?"

Xiang Ling naturally knows that all the drugs currently on the market wait for the disease to appear before developing antidote and vaccine. As Tang Kui said, this passage involves the malicious spread of disease, and the research and development of viruses and antidote are both It will take a certain amount of time and financial resources to complete. In the process of dissemination and development, it will definitely require the cooperation of many parties to achieve it. The scope of personnel involved is wider than imagined, and the benefits are even greater.

"So I guessed that there is someone behind Nanshan."

She knew very well that with her current strength, she couldn't touch Nanshan Biology at all, and even put herself in it. After weighing the pros and cons, she decided to put it on hold for the time being, and sent a text message to Wang Aiya to let the other party live normally. Forget it, she will find a good time to expose it.

"Not asleep yet!" As soon as the door opened, Yu Shi walked into the room.

"Look at something." Xiang Ling closed the computer.

Yu Shi was slumped on the sofa, looking like a boss lying dead, with two dark circles around his eyes that were particularly obvious.

"You look like you're dying from overwork."

"The rhythm of the investigation was more or less disrupted." The interference of the media cannot be ignored.

"Is the suspect still awake?" Xiang Ling probably knew the progress, so she just found a topic and asked casually.

When Yu Shi heard this, his eyes were instantly full of vigilance, and he looked at Xiang Ling very uncomfortable, then he looked away and said, "I didn't wake up, but I personally don't think things are that simple."

"How to say?"

"The evidence point is too clear. Judging from all the clues we have obtained so far, the prisoner who kidnapped Tangtang is undoubtedly Chen Guangxuan himself, and the only doubt we have now is how did Chen Guangxuan bring the body to the roof of the apartment building and abandon it? Why did you jump off the building?"

"Is it possible to accidentally kill and then commit suicide because of guilt?"

Yu Shi shook his head: "It's definitely not because of a sense of guilt. The suicide note he left at that time was very provocative, completely contrary to the three words of guilt."

In addition, she visited Chen Guangxuan's mother again today, and after listening to her explain Chen Guangxuan's past events in detail, she was even more convinced that the case was not that simple.

Chen Guangxuan's mother said that Chen Guangxuan himself used to be a very cheerful person with good grades and good interpersonal relationships. His transformation began around the beginning of high school. Chen Guangxuan's good grades suddenly began to plummet. His mother used to He found dirt on his clothes. He said it was dirty while playing. Later, because his grades slipped too much, Chen Guangxuan automatically applied for a transfer. His mother didn't say anything, but she was much quieter than before. Mother and son The communication between them became less and less, and finally evolved to the point where they only asked to wake up and eat, and the rest of the time was silent.

Even before Chen Guangxuan kidnapped the child, her mother didn't notice anything unusual. She didn't speak or quarrel. Kidnapping the child seemed to be a matter of instant decision, but only the investigators knew. The park's surveillance , the route after the kidnapping, and the jumping off the building were all planned for a long time.

"Can I see the data?" asked Zero.

Yu Shi thought for a while, although there is an investigation confidentiality treaty, Xiang Ling is like a colleague to her. Although she is a reporter and a policeman, the professional perspective is not far behind, and she may even be able to discover some of them from Xiang Ling's perspective. Something not found.

Borrowing Xiang Ling's computer, Yu Shi inserted the flash drive and asked Xiang Ling to read it by himself, while she sat aside to watch it, and saw that the other party watched three videos shot by Chen Guangxuan, and then opened the first and second at the same time. The three videos were played side by side, and then he opened the suspected professional photo editing software to edit the third video. Yu Shi also saw things that he hadn't seen before in the ever-changing light and shadow color adjustment.

Chen Guangxuan in the third video was wearing black gloves, but from the frame-by-frame screenshots of Xiang Ling, it can be seen that in a certain frame, the prisoner briefly showed his wrist.

"Is this a scar?" Yu Shi took a closer look.

Xiang Ling opened his neckline to indicate that Yu Shi compared them, and Yu Shi looked left and right. He was very sure that it was a scar, but there was no need to compare them together.

"I'll give you a reference." Xiang Ling let go of his hand, and opened the live photo taken by Yu Shi when Chen Guangxuan fell from the building. Chen Guangxuan's right wrist was clean without any scars or wounds.

Yu Shi held his forehead, and couldn't believe that he had watched the video hundreds of times, but only one frame revealed a clue.

"There's only one frame, and it's inevitable that I didn't find it. The prisoner may be wearing gloves to prevent people from discovering the difference in his hands." After all, the size of the hands is a clearly distinguishable personal characteristic.

Xiang Ling continued to check other surveillance images. When Chen Guangxuan entered the campus for the last time, he was wearing a gray-blue jacket, but when he fell from the building, he was wearing the black jacket he usually wore. They had already discovered it at that time, but because all the evidence pointed to Chen Guangxuan, their inference was that Chen Guangxuan hid the black coat somewhere, wore it when committing the crime, and then returned to school to commit suicide.

"Our previous speculations were all based on the fact that Chen Guangxuan was the prisoner, but now that we have discovered different clues, the scope of our speculation is wider. Assuming that the prisoner is someone else, then the real prisoner is likely to have stolen Chen Guangxuan's coat, which can explain why Chen Guangxuan stopped wearing that black coat a few days before committing the crime. It's the illusion of a criminal."

Xiang Ling pointed to the fake Chen Guangxuan in the monitoring screen and the real Chen Guangxuan after he fell from the building, and said: "Look, the dress is exactly the same, the clothes and shoes are from the school, so no matter who it is, as long as it is close to Chen Guangxuan's figure, put it on. With his jacket, wearing a mask, and deliberately imitating his walking steps, anyone can be Chen Guangxuan."

"That must be someone who is very familiar with Chen Guangxuan, his friend or schoolmate."

Just in the middle of the conversation between the two, Shuxia called: "You are really thanks to me working so hard to work overtime for you."

"You all want me to thank you for doing your job, what about professional ethics?"

Yu Shi rolled his eyes, this group of people really cheated as much as they could, until a meal was a meal.

"Okay, okay, let me tell you, the body is indeed Tangtang's. There is nothing wrong with it. The time of death was around eleven o'clock on Tuesday night. The cause of death was suffocation. The report showed that there were a lot of sleeping pills left in Tangtang's body. It should be She has been in a state of deep sleep all the time, and the sugar content in Tangtang's body is not usually high, it should be because she has eaten high-sugar foods."

"Understood." Yu Shi hung up the phone and said, "The time of death was around eleven o'clock on the night of disappearance, after Chen Guangxuan fell from the building."

"You should sleep well tonight! You will be busy again when you wake up tomorrow." When Xiang Ling returned the flash drive to Yu, she had read enough, and it was time for the police to investigate by themselves.

The next morning, when Xiang Ling woke up, Yu Shi had already left the house. It seemed that the other party would not be able to rest well if the case was not investigated for a day.

The police gave up all previous speculations, re-investigated the suspects, and conducted an in-depth investigation on Chen Guangxuan's interpersonal relationship. Yu Shi and Li Yu returned to the apartment and found Uncle Zheng. She wanted to ask about the invalid surveillance that night. matter.

Uncle Zheng recalled: "That night I had a stomachache, so I went to the toilet. When I came back from the toilet, I saw that the surveillance screen was black. Later, I went to check the wires and found that it was bitten by a mouse. Go throw it away."

"Why do you suddenly want to go to the bathroom?" Li Yu asked.

When Uncle Zheng heard this, he stared at Li Yu with an inexplicable expression on his face and asked, "Will you find a reason when you go to the bathroom?"

Li Yu shook his head and said, "That's not true, that's not what I meant."

Yu Shi calmly explained: "He meant to ask if you had eaten anything, why the surveillance system broke just after going to the bathroom, or did you really want to go to the bathroom naturally?"

"That's not true. I usually go to bed once every morning. That night, after eating noodles and drinking coffee, I felt a little uncomfortable in my stomach, so I went to the toilet. The power was cut off halfway through the toilet, which was very eerie."

Uncle Zheng's facial features followed his mouth, and his expression should be what he said, very concrete.

"Why didn't you mention the power outage before?" Li Yu asked.

"It's nothing special, it's just an ordinary trip." Uncle Zheng didn't take the trip at that time as a thing at all.

"After you went to the toilet, the power went out, and the surveillance failed after the power outage. If all these coincidences add up, I could win the lottery."

Li Yu sighed, if there were so many coincidences in the world, then he should buy some lottery tickets, and he might win at some point.

"Did you buy the noodles and coffee yourself?" Yu Shi asked.

Uncle Zheng shook his head: "I ordered the noodles myself, not the coffee. A student brought it for me when he came back from home."

Yu Shi asked, "What number does that student live in? Do you know his name?"

"Number 706, Lin Muxin."

Yu Shi took Li Yu to No. 706. Not long after he rang the doorbell, someone answered the door. The person who came was a very young girl, about the same age as Uncle Zheng said, and I heard that she had just entered college.

"Hello, who are you?" Lin Muxin had wet hair and a towel draped over his shoulders, apparently just after taking a shower.

"Hello, we are the police. My name is Yu Shi and his name is Li Yu." Yu Shi smiled politely.

"Are you in charge of the water tank case? You have something to do with me?" Lin Muxin turned sideways and made an invitation gesture to invite the two into the room.

Yu Shi and Li Yu also unceremoniously followed each other's invitation to enter the house, they couldn't wish more.

"No, I just came over to take a look. I heard from Uncle Zheng that the residents on this floor have left temporarily because of the stop of water supply. Why are you still here?" Yu Shi sat on the sofa.

Lin Muxin filled two bottles of water with a clean water glass, Yu Shi saw that it was mineral water bought outside, so he took it.

"Student, can I have a look at the design and structure of this house? Because I'm looking for a house to move recently, I want to see this place." Li Yu asked.

"You can do whatever you want." Lin Muxin finished speaking and sat on the sofa diagonally opposite Yu Shi.

"I'm leaving soon, I just packed my clothes." Lin Muxin pointed to the pink suitcase in the corner.

Yu Shi glanced at the pink suitcase, it was neither too big nor too small, just enough to hold a child.

"By the way, do you usually only drink water bought outside?" Yu Shi asked.

She saw it from the moment she entered the room. The corners of the room were filled with more than a dozen large and empty mineral water bottles, which were definitely not the amount that could be drunk from yesterday to now.

"Because my mother said that the tap water was not very clean and told me not to drink it, so whether I was at home or living alone, I drank bottled mineral water. I have kept these bottles for about a week, and I plan to throw them away together later. , I used the rest to wash my hair, because I don’t know when the water supply will be restored.” Lin Muxin was a little embarrassed by the pile of bottles in the corner.

"You came out to rent a house by yourself at such a young age. A woman like you who lives alone should be more careful. You let us in before the two of us showed you your ID just now." Li Yu watched the room and sat next to Yu Shi.

"Don't worry, I have a weapon." Lin Muxin gestured to the two to look at the tennis racket in the corner, and she was wearing a wristband from the beginning, she looked like a tennis player.

"Finished? Are you satisfied?" Yu Shi raised his eyebrows and asked.

"It's not very suitable for me. I firmly oppose the bedroom being upstairs." Li Yu showed a disgusted expression in a matter-of-fact manner.

"Is it because the police are tired from work and don't want to climb the stairs?" Lin Muxin made a sound similar to being amused.

"No, it's because he likes to drink, and when he's drunk, he likes to crawl on the ground like a loach." Yu Shi didn't mind exposing his partner's bad habits in front of strangers.

At this moment, Yu Shi glanced at the message he had just received on his phone, then got up and said, "Sorry for bothering you for so long, we have something to do in the bureau and we have to go back first, let's throw away those bottles for you! "

"Although I'm sorry, I really can't take that much by myself, so I will trouble you."

Lin Muxin sent people to the door, watched the two take all the empty bottles, and bowed slightly to express his thanks before leaving.

Yu Shi and Li Yu were carrying a lot of empty bottles. As soon as the elevator door closed, Li Yu said, "Jinnian High School."

"She just let us in the house and let us touch her things, she has already shown that she is not afraid of what we may see or find in the house.

"Are these bottles still inspected?"

"Test."

To be honest, even if something is detected from the bottle, it cannot be regarded as evidence, because it is not obtained through serious channels, but they are only testing with the mentality of trying, and the final result is indeed nothing, except A whole bunch of fingerprints and nothing.

And there is no evidence, and there is no way to apply for a residential search warrant.

The goal is shifted from Lin Muxin herself to her classmates, friends and school teachers. Everyone evaluates her as a standard model student. She is good at studying and sports. Going back to junior high school, there were gradually some different speeches.

"Good grades and good sports, the only flaw is that you can't empathize with others."

"When everyone is watching a tear-jerking movie or a horror movie, she must be the calmest one in the class."

"I'm very selfish when I do things, and I don't think much about others."

"Not comforting others."

"I've seen her play with a pregnant kitten. She probably likes small animals."

"I remember that the kitten said later that it had gone to another place and was never seen again anyway."

Comments like these made Yu Shi feel like he was hallucinating for a moment. Lin Muxin seemed to be two completely different people in junior high school and high school, with a serious sense of separation in his image.

"Ah, you mean Lin Muxin. She used to be neighbors with Chen Guangxuan, and they had a good time when they were young. I heard that Chen Guangxuan confessed his love to her in junior high school. It seems that they have been dating for a while."

"and after?"

"Later it seemed that Chen Guangxuan dumped her. Anyway, I don't know the inside story, but I heard that from a certain day, Chen Guangxuan stopped talking to her."

At this point in the evaluation, Lin Muxin and Chen Guangxuan began to meet each other.

The second time Yu Shi and Lin Muxin met was at Lin Muxin's home. She personally visited her and contacted her in the name of assisting in the investigation.

"I asked Chen Guangxuan's former classmates. They said that you knew him before and dated him for a while."

Lin Muxin was at a loss when he heard this, and said, "Well, he and I have been neighbors since we were young, and we also liked each other. We dated for a while in junior high school. At that time, my tutoring was very strict. After my mother found out, Let us separate."

"Other students said that he proposed to separate."

"That's not true. After I proposed to break up, he might be a little angry or couldn't understand my decision, so we didn't talk much after that. Maybe in the eyes of others, I was the one who was dumped." Lin Mu Laugh hard.

"After that? Do you know why Chen Guangxuan became like this?"

"I don't know the specific situation, because I am one year older than him, so when he first entered high school, I was already a sophomore. Our social circles are different, so I didn't pay much attention to him."

"May I know when you two broke up?"

"At the end of the second half of my third year of junior high school."

"By the way, I think you like tennis very much. Recently, an animated movie about tennis was released in the island country. Our city only had two games at [-] am and [-] noon last Tuesday. Have you watched it?"

"No, because the school club has some activities, so I prepare at home."

"That's a pity, I've heard the rave reviews."

"I'm also paying attention to that movie, and then I can just pay to watch it on the Internet."

Yu Shi walked out of the house watched by Lin Muxin's smile, and just got into the car when she received a voice message from the big man.

"Wu Quyuan said that she was at home on Tuesday and stayed with Lin Muxin all day, until she sent Lin Muxin back to the apartment at night."

Yu Shi couldn't help but want to take a picture of the steering wheel, but when he glanced in the direction of Lin Muxin's house, she was still standing at the door waving at her, so she could only forcefully smile and wave casually before driving away.

Lin Muxin would always throw something to them from time to time, and then take it back. After repeated several times, even a fool would feel that something was wrong.

To deal with extraordinary people, only extraordinary methods can be used.

Soon, the relevant residents received the news that the water supply was restored on the floor. Lin Muxin quickly packed up her luggage and returned to the apartment at night. As soon as she walked into the door of the apartment, she found that the person on duty in the guard room had become Liu Shangjin. .

"Huh? Brother Liu, aren't you not on the night shift?" Lin Muxin walked to the window and started a conversation with Liu Shangjin.

Liu Shangjin shook his head helplessly and said, "There is no way. Uncle Zheng said that his old mother suddenly passed out and went to the hospital, so she went back home on vacation."

Lin Muxin asked worriedly: "Ah, is Auntie okay? Did Uncle Zheng tell you anything?"

"That's not true. He hasn't contacted me since he went back. It's probably quite serious. He told me about cardiovascular blockage at the beginning. I don't think he will be able to come back in a short time."

"That's on the night shift, can you?"

"I can't do it, but I have to do it. I'm still in the probationary period, and I have parents to take care of. I have to earn money to support my family." Liu Shangjin felt even more helpless.

"Oh, come on! I'll come over and chat with you when I'm free. Don't worry."

"It's my wish to have a beautiful woman to chat with." Liu Shangjin cracked a smile, so that outsiders can know that he is yearning for spring.

After bidding farewell to Liu Shangjin, Lin Muxin took the elevator back home. She found that the corridor on the seventh floor was dark and the lights were not turned on. But in the dark, she could clearly see that she was the first resident to come back. None of the other neighbors came back.

After turning on the light in the corridor, she entered her room and placed her luggage in a corner. She couldn't wait to open the refrigerator, and took out the popsicles she had made before and put them in her mouth.

Slumped on the sofa, she turned on the TV, and the TV news was still repeating the same case. Since the body was discovered, the public has never been tired of criticizing the police. The Internet army changes its tricks every day, trying to Use bad comments to pursue and uphold the justice in your own mind.

Taking a look at the time, she felt that it was time for her to go out, so she finished eating the remaining popsicles, threw the sticks into the trash can, put on a thick coat and went out.

Liu Shangjin was playing on the phone in the guard room, and when he saw Lin Muxin coming out, he opened the window and asked, "You just came back, are you going out again?"

"Go out and buy some supper, and I'll bring you a hot drink when I come back." Lin Muxin waved his hand and disappeared around the corner.

Nearly an hour later, Lin Muxin came back with a lot of spoils. She kept her promise and put a cup of hot drink in front of Liu Shangjin, and said, "Here you are, thank you for your night shift."

"You really bought it!" Liu Shangjin took the drink gratefully, the heat source leaked from the cup, and the hands that had been frozen for a long time warmed up.

"Drink it gratefully! When Uncle Zheng was around, I never bought it for him a few times." Lin Muxin put another bag by the window, which was full of skewers.

"I haven't bought it a few times, but I still bought it!"

Lin Muxin said seriously: "But he doesn't have skewers, you have."

Liu Shangjin laughed unconsciously, and said, "Would you like to eat a skewer with me, that beauty? It's boring to eat by myself."

Lin Muxin put on a displeased expression and said, "You want me to stand in the cold wind and eat skewers. I'm not sick."

"Then come in quickly, don't freeze." Liu Shangjin got up and opened the door of the guard room.

Lin Muxin hesitated at the door, and asked, "Can I just go in here?"

"Is there anything you can't go in, fast forward, fast forward, it's freezing." Under Liu Shangjin's warm greeting, Lin Muxin finally walked into the guard room.

Liu Shangjin moved her a stool, and the two began to eat skewers and drink.

Lin Muxin ate and ate, her eyes were only on a computer on the table, and there were several separated images on the screen, which showed the scene in the apartment. She asked, "Is this real-time monitoring?"

"Well, I have to switch occasionally to look at other places. After all, there is only one computer, but there are several monitors." Liu Shangjin clicked a few times with the mouse, and the monitor screen changed.

"So that's how it is." Lin Muxin's eyes sparkled as if she saw something new, and soon she noticed that among the different screens that Liu Shangjin switched, one of them was obviously different from the others, and she asked: " Why does this surveillance look clearer?"

"Ah, this is a newly replaced camera. The previous one broke down two days ago, so I replaced it with a new one. However, because the person from the installation company said that the wires in our apartment were bitten by mice, it is recommended not to use all the cameras. The wires of the camera are put together to avoid the same thing from happening again, so now only the wire of this camera is independent, and the others remain the same." Liu Shangjin explained.

The newly replaced camera was just aimed at the entrance and exit of the apartment. Even if the others were broken unfortunately, this camera could still continue to shoot. As long as any suspicious person entered the apartment, the surveillance would definitely capture it.

"What if the bad guys go through the back door of the apartment?" Lin Muxin asked sincerely, after all, the apartment has more than one entrance.

"The owner has spoken, and now the back door is temporarily closed and locked, because the murderer didn't know if he entered the apartment through the back door that day. They are worried that this kind of thing will happen again, and they are considering changing the electronic lock. When the time comes, every resident will A card is issued, and those who want to go through the back door punch the card and the door opens."

"Do you still need to consider this kind of thing? It's better to pretend!" Lin Muxin bit the skewer, shaking his right leg on top of his left.

"Who knows, it may be quite expensive! I think it's better not to change it. Think about it, if some residents come to say that the card is gone, there will be many problems in the follow-up processing, which is very troublesome." Liu Shang Jin stared at the screen thoughtfully, then turned his head to look at Lin Muxin and said, "Anyway, I have the key."

Lin Muxin didn't understand what the other party meant by the latter sentence. She just felt that the surroundings were getting colder, so she left the remaining skewers with Liu Shangjin, and she stood up and said, "I'll go back first, tomorrow I have to go to school in the morning."

Liu Shangjin threw the bamboo sticks into the trash bag and asked, "Are you still going to school during the winter vacation?"

"College freshmen, there are more activities."

Liu Shangjin stared at Lin Muxin's back from the window and smiled.

The author has something to say:

Don't trust anyone easily, even those who seem nice on the outside.
