Wu Nian's words surprised Teng Qian and Lin Mubai slightly, they weren't sure why Wu Nian said this, "Do you have any evidence?" Lin Mubai asked.

"There's no evidence, but it's been a matter of the five of us all along, and I knew five years ago that there would be such a day. Wu Nian said slowly.

"What did you do together five years ago?" asked Teng Qian.

Wu Nian closed his eyes, "This...... If you ask them who they are, they won't say, and I won't say either. ”

"You'd better cooperate with us so that we can catch the murderer. Teng Qian said patiently.

"You would say such a thing, just because you don't know, it is far better to be killed by this murderer hidden among us than ......" Saying this, Wu Nian suddenly laughed and closed his mouth.

"What's better than that?" Lin Mubai asked.

"Nothing, if you want to ask me where the two million I received three years ago go, I can tell you that I donated them all...... All of them were donated. Wu Nian said this, and the smile on his face became brighter.

Teng Qian squinted at him, "You donated all the money, which proves that you still have good intentions in your heart, and if you tell the matter, maybe there will be no more deaths." ”

"Naïve...... Can you be so naïve as a policeman?" Wu Nian suddenly said with a cold face, "You haven't thought about it, we all avoid talking about it, and we would rather die than say why?"

"I'm by no means the last one you asked, I guess...... You'll leave Sun Meng last, but I advise you, what he said...... It's better not to believe. After speaking, Wu Nian leaned back, like Zhao Yong, he didn't want to say anything.

Although Teng Qian was on fire in her heart, she also knew that it was useless to consume it like this, so she and Lin Mubai went out and went straight to Sun Meng's room.

Sun Meng didn't match his name very much, he looked lean, and put on a pair of glasses to make him look more gentle, "I'm the last one you asked, it seems that I'm the most difficult person to deal with in your hearts." ”

Teng Qian smiled when she heard this, "I just looked at your resume, it's not simple, a top psychology student from a famous university." ”

"It was a long time ago. Sun Meng said lightly.

"It's not easy to have a college student like you in the village where you once lived. Lin Mubai said.

"Yes, the year I was admitted to university, the whole village was celebrating, and I was the first college student in our village to go to a prestigious college. Sun Meng said with some nostalgia.

"It's an honor, but you don't seem to cherish it. Teng Qian looked at him and said.

"Glory, cherish?" Sun Meng said mockingly, he glanced at Teng Qian, and the corners of his eyes were dyed with a smile.

"You'll never know that when you're famous in a place like that, you're going to be carrying something that is far deadlier than the glory. ”

"Let's talk about five years ago. Despite the slim hope, Teng Qian still wanted to give it a try.

Sun Meng stared at Teng Qian for a while, and then looked at Lin Mubai instead, "You don't know much, I don't think those three people probably didn't say anything, yes, they all know in their hearts what kind of people they provoke." ”

"Make it clear. Lin Mubai squinted and said.

"What are you talking about, there must be a murderer among the four of us, guess it will be me?" Sun Meng said with a smile.

"Sun Meng, you'd better be honest. Lin Mubai stared at him and said word by word.

Sun Meng sat on the chair, clasped his hands on his legs, and his legs shook slightly, "Okay, I confess my guilt, I killed the person." ”

With his words, Zhao Jie pushed open the door and gestured to Teng Qian, Teng Qian frowned slightly and walked out, as soon as he went out, Zhao Jie said, "Boss, they all confessed, and they all said that they killed themselves." ”

Teng Qian's eyes widened slowly, she turned around and went back to the interrogation room, slapping the table, "Let's talk about it, why do you all have to confess your guilt, you all have to admit that you are the murderer." ”

Sun Meng leaned back and spread his hands, "Because we are the murderers, this is a fact." ”

This posture made Teng Qian gasp, this case has gone around and around so many times, it seems to have gained something, but it is like stepping into a fog, there is nothing.

Lin Mubai looked at Teng Qian, who was holding the table with one hand and inhaling, turned his head and said, "In fact, it is because you all think that it is better to stay in prison than to live outside." ”

"And the reason why they chose to say it at this point in time is to prove that they don't believe you, they don't believe that you will be silent without saying anything, so ...... You have to think clearly, if you are not the murderer, then they don't trust you, and after you are released, you must be the first to die. ”

Lin Mubai said in a calm tone, his words made Sun Meng raise his eyebrows, and he leaned forward slightly, "You are right, maybe you let us go, and I will die next." ”

"I might as well tell you why, what it took them five years to figure out, I knew five years ago. Sun Meng said this and sighed.

"You should be the most familiar with Qian Cheng, let's talk about what you know about him. Teng Qian watched for a while, then sat down again.

"He...... Silly, mentally abnormal. When he said that he was mentally abnormal, Sun Meng smiled faintly.

It's just that this smile is mixed with more than one layer of meaning, "Why is he not mentally normal." Teng Qian asked.

Sun Meng shrugged his shoulders, "It's better to ask him than to ask him, how do I know why he is not mentally normal, and I am not to blame for his abnormality." ”

Teng Qian put away the things on the table, "You'd better pray that we can find evidence to prove your guilt, otherwise, no one can save you if you don't save yourself." ”

Coming out of the interrogation room, Teng Qian ordered everyone to disperse to the house of the five people and bring back all the valuable things and information, she and Lin Mubai sat in the monitoring room, watching the every move of the five people.

After a while, Zhao Jie brought Zhou Lele over, the little girl was very nervous when she entered the police station for the first time, but when she saw Teng Qian, she was relieved.

"It turns out that you are a policeman, so I said, how can I be found by the police as a good law-abiding citizen. Zhou Lele said with a smile.

Teng Qian smiled apologetically at her, "It happened suddenly, the man who bought the dye before, do you remember his specific appearance?"

"If it's the handsome one, I remember, the other one, I should be able to recognize it. Zhou Lele said.

Teng Qian took him to the monitoring room, "Is there anything in here?"

Zhou Lele looked carefully, stretched out his hand and pointed at one of them and said, "It seems to be ...... It's him. ”

"Are you sure?" Teng Qian asked, Zhou Lele pursed his lips, "It should be him." Teng Qian stared at Wu Nian on the monitor and narrowed her eyes.

"Do you doubt him?" asked Lin Mubai.

"The red dye in the first case is the same as this case, because it is an environmentally friendly new product, so the entire S market is exclusively sold. Teng Qian pointed at Wu Nian as she spoke.

"I checked before, there are two people who have bought this dye, one is Cong Ye, and the other is Wu Nian who Zhou Lele pointed out just now. After Teng Qian finished speaking, Lin Mubai raised her eyebrows slightly.

"Why don't you suspect Cong Ye?" Lin Mubai asked, Teng Qian turned her head to look at him and shook her head, "The first thing I suspect is him, but he doesn't fit the characteristics of a suspect at all, and this case has nothing to do with him, right?" ”

"So...... I'm going to ask, Wu Nian. After speaking, Teng Qian walked into Wu Nian's interrogation room with the materials, and Lin Mubai squinted and sighed and followed in.

Regarding Teng Qian and Lin Mubai's entry into the door, Wu Nian behaved very calmly, without any waves, Teng Qian pulled out a chair and sat opposite him.

"You've bought red dye recently, right?" Teng Qian's words made Wu Nian raise his eyebrows slightly, his eyes flashed slightly, "Buy dye?" As he spoke, he nodded, "It seems that he bought it." ”

"The dye you bought is the same as the dye that appeared in this case and in the previous case, can you explain that?" asked Teng Qian.

"It's all dyes, and the ingredients should be similar, and I don't know why it's the same, maybe it's just a coincidence. Wu Nian said helplessly.

"It seems that you don't know very well, the red dye you bought is a new type of environmentally friendly dye, the only one in the city to sell, because of the pursuit of environmental protection, so a lot of adjustments have been made in the composition, and there is no similar model. Teng Qian squinted and said.

Wu Nian's face sank slightly, but it was only an instantaneous matter, he frowned slightly, "I bought the dye for other people's home decoration, are you suspicious of me now?"

"Even if the dye is special, I am not the only one who has bought it, and even if I have something to do with this case, it is impossible to convict me because of the dye, which is not evidence. Wu Nian said lightly.

Teng Qian stared at him, "Do you know him?"

Wu Nian glanced away and shook his head, "I don't know." ”

Teng Qian took back Wang Chengan's photos and lined up the photos of Zhao Bo, Zhou Ying, and Zhang Fan, "Do you know them?"

Wu Nian confirmed again, then shook his head, "I don't know them, what's the matter, they have something to do with this case?"

Teng Qian stared at him, and finally pushed Wang Yaxin's photo over, "She...... Do you know?"

Wu Nian glanced at it and said decisively, "I don't know." ”

Teng Qian immediately got up and walked out with the documents, Lin Mubai followed out when he saw this, and as soon as he went out, he saw Teng Qian leaning against the wall and holding the documents thoughtfully.

"What, he lied?" Lin Mubai asked.

Teng Qian shook her head, from the behavioral and psychological analysis, Wu Nian didn't have any signs of lying just now, but she just couldn't identify with Wu Nian like she agreed that Cong Ye didn't lie.

"Wu Nian is right, we just suspect that there are many people who buy dyes, and we can't conclude that he is a criminal just because he bought it recently and is related to this case. Lin Mubai leaned next to Teng Qian and said.

For a moment, the two looked at each other speechless......
