Chen Bai did not speak when he heard Zhang Zhuo's question. Instead, he borrowed a mobile phone from Song Anchun, placed it in two corners of the office, and then turned on the player at the same time.
"Can you hear the music?"
"sure!"
Zhang Zhuo was a little confused, what did Chen Bai mean?
"Is there any? Why can't I hear any sound?"
"You play your own songs yourself..."
Zhang Zhuogang wanted to say something, but he suddenly realized the problem.
"I understand, Qin Jun only needs to find two speakers, and then play low-frequency music. The sound is just loud enough for Li Yan to hear. Li Yan will naturally ask Qin Jun after hearing it, but Qin Jun only needs to
Just say there is no sound."
"Yes, Li Yan will think that something is wrong with her, because there are only Qin Jun and herself in this room, so over time, Li Yan will think that something is wrong with herself."
Chen Bai nodded, but Bai Hongwei, who had never spoken at this time, asked.
"But why is it the cry of a child?"
Zhang Zhuo was a little confused, but Chen Bai put out the cigarette butt in the ashtray and said.
"I'm afraid this has something to do with what they are hiding from us, right?"
"Then Chen Bai, who is this person who assisted the Qin army?"
This is the most important thing, because if you really want to complete the murderous method mentioned by Chen Bai, you will need at least the assistance of a woman.
"We can check Qin Jun to see if there are any women who have close contacts with him, especially some of Li Yan's best friends."
The workload of this job is huge, especially since they have no evidence at all, so all investigations can only be carried out secretly.
"How's it going? Have you found any clues?"
Chen Bai handed the instant noodles in his hand to Li Huan. Li Huan took the instant noodles and shook his head.
"No, I checked various social software and found that Qin Jun basically has nothing to do with these women."
"The phone never came?"
Li Huan shook his head, while Chen Bai seemed to have a headache after receiving Li Huan's reply.
"Don't worry, I'll take a look."
Li Huan knew that there was not much he could do to help Chen Bai, so he had to do his best.
"It's okay, you just have to work hard."
After Chen Bai finished speaking, he leaned on the chair in the office and kept thinking about the case in his mind.
Qin Jun: My wife's mental state has been bad since a year ago. She suffered from insomnia at first. Later, she often told me that she could hear the child's cry.
Lin Yuzhen: Officer, please stop bothering me. This is the curse of the mountain god.
Song Ya: I was walking on the road, and I felt someone push me from behind.
Zhou Xiuping: I drove Lin Yuzhen home, but when we passed the Puzhou Bridge, Lin Yuzhen started going crazy, and then I lost control of the car.
"After graduating from high school, none of the six people took the college entrance examination. In the end, only Li Yan, who came from a well-off family, was not affected. However, these people went to Longcheng Mountain to travel and happened to encounter a mudslide. Among the six, only Liu Shan died."
"etc!"
Chen Bai stood up suddenly, and his sudden movement frightened Li Huan.
"What's wrong? What did you think of?"
Li Huan knew that Chen Bai must have had something in mind with this reaction.
"Our investigation is in the wrong direction. Xiao Wang Dabin and Feng Qianqian are following me!"
Chen Bai didn't explain anything, but directly asked the three people to follow him.
"Teacher Chen, what did you discover?"
"I thought wrong before. I originally thought that Li Yan's case of jumping off a building was the first case, but now it seems that I was wrong. Do you still remember that Li Yan and the other six went to Longcheng Mountain and encountered a mudslide in the end?
?Why was it such a coincidence that only Liu Shan died due to a landslide? Feng Qianqian and I looked at the information of several people before and found that Liu Shan took a full half-month vacation two months before the college entrance examination and came back.
After that, they got pneumonia one after another in their dormitory."
Several people looked at each other, not knowing what Chen Bai was talking about.
"I mean, all of them may be related to Liu Shan, so we are going to the school now to find out about Liu Shan."
Although it has been many years since the incident, the teacher who taught them at that time has not retired and still remembers what happened back then.
"Actually, I have a very deep impression on them. Because of pneumonia, all six people in the dormitory did not take the college entrance examination. The only one among those who was not affected was probably Li Yan. After all, they
The family is rich, but the other girls suffer. Their families are all from other places, and living in a place like Puzhou is very tiring. They just expected their children to get into a good university, but they didn't expect that they would.
This is the result."
"Teacher, the information shows that Liu Shan took half a month off two months before the college entrance examination. Do you know why this is?"
Chen Bai knew that this was the most important thing, so the teacher thought for a while and said.
"I don't know about this, but the only thing I know is that it was because of Liu Shan that the other five people in the dormitory got pneumonia."
"What?"
Chen Bai was a little surprised. He really didn't expect that it was because of Liu Shan and the other five people that they got sick.
"Yes, I can confirm this. Liu Shan felt unwell the day she returned to school, and then the other five people in their dormitory fell ill one after another."
When leaving the school, everyone except Chen Bai was still confused.
"Teacher Chen, what will happen even if we know this? What can these things prove?"
"Don't talk about this yet, let your captain try to find Liu Shan's family first."
Although Xiao Wang didn't know what Chen Bai meant, he still called Zhang Zhuo and explained the situation.
"Teacher Chen, you are suspicious..."
Before Da Binzi finished speaking, Chen Bai nodded. In fact, you can't blame Chen Bai for being suspicious, because this thing is too coincidental.
"Found it, Lane 39, Puzhou Road."
"Walk!"
However, when Chen Bai and others found Liu Shan's parents, Liu Shan's parents were unwilling to cooperate.
"Comrade police, I don't know what case you are investigating now, but I think no matter what it is, it has nothing to do with our daughter, right? My daughter has been gone for many years, and our husband and wife have gradually come out of it. We are now
I just want to live my own life, isn’t that okay?”
Chen Bai nodded. In fact, the reaction of Liu Shan's parents was understandable.
"Brother, I know you are in pain, but I hope you can still tell us what happened that year. Several of Liu Shan's good friends have been involved in accidents recently. I can't tell you in detail what happened, but
I have a feeling that what happened to them is very likely to be related to what happened to your daughter back then."
Finally, under Chen Bai's persuasion, the man told what happened that year.
"My girl has been an obedient and sensible child since she was a child. Although her studies are average, she is pretty good. After entering high school, because high schools all live on campus, she can basically only come back on Sunday morning. Probably
When I was a sophomore in high school, I discovered that my girl didn’t want to go home on Sundays. She just studied at school or went out with friends. At first we didn’t care, but just two months before the college entrance examination, my girl didn’t want to go home on Sundays.
I suddenly came back when I was there. But as soon as I entered the door, I was hesitant and didn't dare to say anything I wanted to say. Moreover, at that time, we obviously felt that the girl was fat."
In fact, when the man said this, Chen Bai roughly knew what was going on.
"After our repeated questioning, the girl told us that she was accidentally pregnant. Now she is three months old, and she knew that if she hadn't told us, she would have been discovered. We were very angry at the time, but we
Knowing that getting angry was not the answer, we had no choice but to take the child for surgery quickly. Because of this, she rested at home for two weeks."
Chen Bai nodded, if that's the case, then everything makes sense. Liu Shan got sick because she had an abortion and was weak, and because all six of them lived in the same dormitory, they were all infected.
.
"Comrade police, did my daughter die in an accident?"
"Brother, we are still investigating this case, and there is no result yet. We will definitely notify you as soon as there is a result."
After coming out of Liu Shan's house, Chen Bai received a call from Bai Hongwei.
"What's wrong? Something happened?"
Chen Bai knew that a call from Bai Hongwei usually wouldn't do anything good.
"Chen Bai, Qin Jun has disposed of all Li Yan's property, and now only Li Yan's house is left."
"What did you say?"
Chen Bai was a little surprised. Didn't Qin Jun say before that he was not qualified to handle Li Yan's house?
"I'll be there soon!"
Chen Bai came to the downstairs of Li Yan's house, and at this time Qin Jun was instructing the moving company to pack the furniture.
"Mr. Qin, are you a little too anxious?"
"Officer, my wife committed suicide. No matter how you investigate, she committed suicide. I really don't want to stay in this place anymore. I have already taken care of my wife's company and I will wait for the money to be transferred in a few days.
.”
Chen Bai knew that it would be useless even if he said anything now.
"Okay, please wait a moment. We can give you your wife in a week at most."
After Chen Bai finished speaking, he took Feng Qianqian and the other three people into the opposite car.
"Chen Bai, are we sure now? This Qin Jun wants to run away. His wife's death is definitely related to him."
"What's the use of saying this now? The problem now is that we can't find any evidence that Qin Jun killed someone."
Bai Hongwei was also a little anxious, but when Chen Bai looked at the people from the moving company, he suddenly thought of something and quickly got out of the car.
"What have you been doing?"
Bai Hongwei saw Chen Bai talking to the people from the moving company and ran back happily.
"Don't worry, the Qin army won't be able to escape this time."
When everyone returned to the police station, Zhang Zhuo looked at the large wardrobe standing in the office and asked with some confusion.
"What is this? Who got it?"
"I!"
Chen Bai patted the large wardrobe and said excitedly.
"This is the big wardrobe in Li Yan's home. In fact, when I first saw this big wardrobe, I was a little confused. How could there be such an ordinary big wardrobe in such a high-end place like Li Yan's home? But you still remember what I said.
Reasoning? Qin Jun has an accomplice, but both the elevator and the stairs in Li Yan's house are monitored. It is impossible to come up openly in such a place, so Qin Jun's accomplice is hidden in
It came from the closet."
Everyone was a little surprised, but Xiao Wang asked a question at this time.
"Consultant Chen, you said Qin Jun's helper was moved up after being hidden in the closet? Didn't the workers feel it at that time? Also, I would like to ask, how did Qin Jun's helper leave?
"
"Of course I took the elevator down. Have you checked the surveillance of the entire building after Li Yan jumped?"
After Chen Bai said this, everyone was stunned. They really had not checked the surveillance of Li Yan after she jumped from the building.
"Chen Bai, there are fingerprints in this place!"
While several people were talking, Wu Di had already detected fingerprints on the inside of the wardrobe.
"But what if fingerprints can be detected? We don't have fingerprints for comparison now."
"Who said that?"
Chen Bai said, taking out a file bag from his schoolbag.
"We can use this for comparison. This is the message Li Yan and her friends wrote to the school before they graduated from high school. There are no fingerprints on them."
After comparison by Wu Di, the fingerprints in the wardrobe belonged to Lin Yuzhen.
"You mean, Lin Yuzhen and Qin Jun conspired to kill Li Yan? But now Lin Yuzhen is dead!"
Zhang Zhuo was a little puzzled, and at this moment Chen Bai suddenly said something.
"What if Lin Yuzhen is not dead?"
"How is this possible? According to Zhou Xiuping's confession, Lin Yuzhen rushed into the Puzhou River in her car. Our people searched for three days and three nights but could not find Lin Yuzhen. How could she still be alive?"
Zhang Zhuo didn't believe it, but to say that Lin Yuzhen was dead was indeed a bit imprecise. After all, they had not seen Lin Yuzhen's body yet.
"No, Lin Yuzhen is missing at most, not dead. It is a fact that we found Lin Yuzhen's fingerprints in the big closet, and we cannot confirm that Lin Yuzhen is dead now."
"But if you rush off such a high bridge, can you really survive?"
Zhang Zhuo was a little puzzled, but Chen Bai's words directly sent shivers down Zhang Zhuo's spine.
"Zhou Xiuping, didn't you survive?"
"Yes! Zhou Xiuping..."
Before Zhang Zhuo finished speaking, Li Huan suddenly stood up and said nervously.
"Chen Bai, something happened!"
Li Huan said and put a video on the big screen. Chen Bai saw in the video that after a woman walked out of the hotel, her clothes suddenly ignited spontaneously. After that, the woman rolled in pain on the street, but finally fell to the ground and stopped moving.
.
"How is this going?"
Zhang Zhuo was a little strange, but Chen Bai noticed that this woman was Zhou Xiuping.
"okay, I get it!"
Xiao Wang put down the phone here, and everyone rushed to the scene of the incident.
"What on earth is going on? How could a person spontaneously combust?"
Zhang Zhuo was a little strange, and the woman lying on the ground had been burned beyond recognition, but from the previous video, it could still be vaguely seen that this person was Zhou Xiuping.
"follow me!"
Chen Bai said as he walked into the health club next to him, where Zhou Xiuping came out just now.
"When did this woman come to your store?"
"..."
The little girl at the front desk was so frightened by the scene in front of her that she couldn't even speak.
"Yesterday, Ms. Zhou just applied for an annual card with us yesterday."
"Did she see anyone yesterday?"
The person who spoke was the lobby manager, but when faced with Chen Bai's question, the lobby manager didn't know how to answer for a while.
"This case now involves human life. I hope you can tell me the truth and don't hide anything."
"No, comrade police, we only have cameras at the door, there are no cameras elsewhere, so we don't know who Ms. Zhou met yesterday."
Chen Bai frowned, first asked Li Huan to check the surveillance, and then came outside again.
"Chen Bai, how can a good person burn out of thin air?"
Chen Bai and Song Anchun looked at each other and said in unison.
"white phosphorus!"
"white phosphorus?"
Seeing Zhang Zhuo's confused look, Chen Bai opened his mouth to explain.
"Actually, this matter is very simple. White phosphorus is a simple substance of phosphorus, and it easily burns when it encounters high temperatures of about 40 degrees."
After Chen Bai finished speaking, he looked up at the sun. Xiao Wang quickly took out his phone and checked the temperature.
"That's right, today is exactly between thirty-seven and forty degrees."
"The murderer applied white phosphorus to the clothes of the deceased in advance. Because the air conditioner was on for a long time in the health club, the temperature was naturally not that high. But when Zhou Xiuping walked out of the health club, when the clothes came into contact with the high temperature outside, the temperature reached the point where the white phosphorus spontaneously ignited.
Of course something will happen."
Zhang Zhuo nodded, while Chen Bai and Song Anchun secretly rejoiced that if Zhou Xiuping hadn't had such a strong smell of white phosphorus, they wouldn't have noticed it. Of course, because white phosphorus is poisonous, Chen Bai also evacuated with everyone at the first time
attracted the crowd at the scene.
"Li Huan, have you found any clues?"
Li Huan shook his head. There were many people entering this health club yesterday, so he didn't know who was suspected at the moment.
"Wait a minute!"
Chen Bai and Feng Qianqian yelled at the same time, because at this moment they seemed to see a familiar person on the surveillance camera.
"Is this person Lin Yuzhen?"
"It seems like it's true!"
Zhang Zhuo was also a little surprised. He didn't expect that Chen Bai was really right about this matter.
"Actually, this is nothing. After all, even Zhou Xiuping was rescued when her car fell into the water. It is normal that Lin Yuzhen did not have any accidents."
After Chen Bai finished speaking, he turned to look at the lobby manager just now.
"Which room did this person stay in last night?"
"201!"
Chen Bai brought people to 201, but by this time the staff had already cleaned up the scene, so there was nothing left to see.
