Criminal Investigation: Collapse

On the way back to the Municipal Bureau, Jiang Yin took Liu Sichan to have some casual dinner near the Municipal Bureau. Although the restaurant was hygienic and delicious, Jiang Yin didn't know why he felt a whole lot of dissatisfaction. I'm sorry, but Liu Sichan ate one as good as two.

Jiang Yin casually took out two pieces of paper from his pocket, and helped Liu Sichan wipe off the oily corners of her mouth. Liu Sichan was startled, and then said "Thank you" rather shyly.

Jiang Yin smiled and didn't speak.

When the two returned to the office of the Municipal Bureau, Wen Lixi and the others also had dinner and followed the newly discovered clues in the conference room.

"Team Jiang, at the time of the [-]th, I asked several students who were in the same class as Professor Qian one by one, and they all confirmed that what Professor Qian said was correct. Li Yecheng really didn't pay much attention to other students except Duan Rao. At that time, there were indeed rumors about the two of them in the college, but as for the experimental subject that Li Yecheng was busy at that time, basically no one knew." Wen Lixi saw Jiang Yin and Liu Sichan coming in through the door of the meeting room , said.

Jiang Yin nodded, and Wen Lixi took another report from his hand and handed it to Jiang Yin, "There is also a report from the trace inspection department and physical evidence department."

Jiang Yin flipped it casually and raised an eyebrow, "It is certain that Li Yecheng killed Duan Rao."

Wen Lixi nodded, "The murder weapon found at the scene and the fingerprints extracted from the doorknob and freezer belonged to Li Yecheng alone, and half of the blood fingerprints extracted from the rope were also Li Yecheng's, so the evidence It's confirmed."

"But what about the first four victims?" Jiang Yin still looked at the things on the report.

"Except for the discovery of Feng Ningning's blood on the rope, there is no further progress." Wen Lixi replied.

Jiang Yin nodded, and just as he was about to speak, Pei Shishi stumbled in from the meeting room, holding a few documents in his hand, panting and said: "Brother, I discovered something."

Then, Pei Shishi took a breath, and then continued: "The other day we discovered that the monitoring of Li Yecheng's entrance guard room did not exist in the records of the cultivation center, and then I just contacted the person who contracted this job at that time. company, but their installation record has this monitoring.”

Jiang Yin put down the report in his hand and signaled Pei Shishi to continue.

"Then, I asked them to find the project leader who was in touch with the cultivation center at that time. The project leader said that when they were talking about the project with the cultivation center, there was indeed no such monitoring in that position, just when the project was about to start. , Someone called and said that a surveillance camera was going to be added to that location.” Pei Shisi let out another breath, “The person in charge of the project said that the reason why he remembered it so clearly was because the person said that he was caught in it.” Just install the things in the middle of the project, and you don’t need to record them in the book. When the time comes, you will double the money and call him privately. Although he didn’t refuse at the time, he kept an extra thought and recorded the audio, fearing that someone would mess with him. .”

"This surveillance is not in their files, which means it is a black surveillance." Wen Lixi said.

Pei Shishi nodded, "That means someone wants to monitor something here."

Jiang Yin was silent for a moment, and asked Pei Shishi, "Where is the recording from the person in charge of the project? Do you know the account that sent money to him privately at that time?"

Hearing this, Pei Shishi took out a USB flash drive from his pocket and handed it to Wen Lixi who was sitting in front of the computer. Wen Lixi took it and plugged it into the computer.

Inside the flash drive is a recording and a few pictures.

"Look at the picture first." Jiang Yin turned around, took two steps and stood behind Wen Lixi.

The first picture is a screenshot of the text message that the project leader received the money at that time, and there is a card end number on it. The second picture is a screenshot of the call records on the mobile phone of the project leader at that time. Chapter 3 was transferred by Pei Shishi The communication records of the person in charge of the project, compared with the two, are indeed exactly the same.

With his eyes, Jiang Yin signaled the little comrade in the information group to look up the owner of the phone number and the owner of the tail number in this transaction. The little comrade copied down the two numbers and trotted out of the conference room.

"Listen to the recording." Jiang Yin said.

Wen Lixi clicked on the recording. The voice of the person in charge of the project was very clear, but the voice on the other end of the phone was a bit noisy, and he could only roughly hear the outline and meaning of a voice.

Liu Sichan, who had been silent all this time, suddenly said, "Can you amplify your voice?"

Wen Lixi heard the words, and turned the volume to the loudest. Although there were many people in the meeting room, they all stopped their movements at this moment, and even the sound of breathing was reduced a lot. At this moment, in this room, only wandering Listen to the voice in that recording.

"I will double the money to your card..." It was the voice of the person on the other end of the phone.

At this time, Liu Sichan leaned her body, tried to get close to the sound outlet of the notebook, and said to Wen Lixi, "Please play this sentence again."

"I'll double the amount of money to your card..." Before the words could be said, Liu Sichan said, "I heard the sound of a pipe knocking on the ground!"

"Pipe?" Jiang Yin repeated the word.

"Yes, it's the sound of a pipe hitting the ground! And it shouldn't belong to anyone else. After all, this person is talking about such hidden things, and there should be no one else around, so..." Liu Sichan stood up straight and looked at Jiang. Yin said.

"On the opposite side is a pipe-smoker." Wen Lixi raised his eyebrows, "There are not many people smoking pipes these days."

"Besides, don't you think this voice is familiar?" Jiang Yin looked sideways at Liu Sichan.

Liu Sichan was taken aback, closed her eyes lightly, checked her mind, opened her eyes suddenly, and looked at Jiang Yin, "It's a bit like the Professor Qian I met this afternoon?"

Jiang Yin nodded, "Fourteen, send it to test and analyze the voice to see if it matches Professor Qian He'an."

After finishing speaking, Jiang Yin pinched the report on the side again in his hand, and said to Wen Lixi: "Apply for an arrest warrant and formally arrest Li Yecheng, Gu Xin, and Tian Wendong."

At this moment, the street outside the window is already brightly lit. The light is within her ability, filling every inch of darkness as much as possible, or maybe because a lampshade of a certain street lamp is missing or for some other reason, the light shines brightly. It is like every gap or redundant place in this world, these minutiae are what they, the police, need to trim.

This night is destined to be a night of lights all night in the Municipal Bureau.

"Director Li," Jiang Yin put the report in his hand in front of Li Yecheng who was already sitting in the interrogation room, smiling politely, "Let's have a look."

Li Yecheng's hands were already imprisoned by handcuffs, and he took the report in a rather comical manner. His face still didn't have much emotional fluctuations. Presumably, when he saw the arrest warrant, he had already thought that the police had discovered Duan Rao. body and the basement.

Li Yecheng put the report together and put it on the table in front of him, "You searched the National Public Research Institute in advance, so you are not afraid of being punished for violating discipline?"

"Hey," Jiang Yin sat on the bench in front of Li Yecheng, crossing his legs, "You are such an authoritative figure, you dare to kill people in the National Public Research Institute, and you are all promising young talents in the academic field , this is just a matter of time, I think the higher-ups will definitely not criticize me, right? Director Li."

"I said that I only killed Duan Rao, and I didn't kill the other four, do you believe me?"

After a moment of silence, Li Yecheng spit out such a sentence from his mouth.

Jiang Yin poked Li Yecheng's eyes directly, "But we found your blood fingerprints on the rope stained with Feng Ningning."

Li Yecheng nodded, "I did touch the rope, but the blood was just accidentally stuck on it when I was touching the rope."

"Is there any evidence to prove that you didn't get it after you killed Feng Ningning?"

Li Yecheng was stunned, "I have no evidence."

"Then it's over, I really want to believe you, but the evidence tells me that I can't trust you..." Jiang Yinsong shrugged.

"To be honest, Director Li, I'm more curious why you are so obsessed with such an anti-human and deviant experiment? And why did you kill Duan Rao? Is it because she knew something?" Jiang Yin asked.

Just now, the Beishan District Bureau called, saying that when Chen Lu's parents met Duan Rao, Duan Rao said something crazy: "I, I have grasped the weakness of human beings, let me tell you, your daughter Shameless being a mistress, a stinky bitch who destroys other people's marriages, deserves to be treated as an experimental product, deserves it, deserves it, deserves to die!"

Although this sentence is the language of madness, the information contained in it is like a bomb.

Hearing Jiang Yin's words, Li Yecheng felt as if he had been dialed to the opposite scale, and suddenly he was furious and emotional, "Anti-humanity? Deviant? Let me tell you, this is a great technology, and I have spent half my life on it. painstaking efforts, for this great experiment."

As he spoke, Li Yecheng even started to pat the table in front of him, expressing his protest and anger towards Jiang Yin's adjective.

"Then can the living person do the experiment?" Jiang Yin saw the needle, and there was still some anger in his voice. This anger fell in Li Yecheng's ears, which was Jiang Yin's disrespect for his experiment.

"I didn't, I didn't!" Li Yecheng's mood gradually increased, "It's all that woman Duan Rao!! It's all her! It's her drug, I have to do it!"

"What?" Jiang Yin asked.

"Do...do!" Li Yecheng slapped the table more vigorously, mixed with the sound of strong contact between the human body and the object, Jiang Yin heard a sentence he had been waiting for for a long time.

"Use those shameless people for experiments!"

"very good."

Jiang Yin curled his lips and deepened the smile on Li Yecheng who was still very excited, "I hope that when you see the sun tomorrow, you can understand what I said."
