Outside a high-end community, Gu Chen, Officer Wang and Lu Weiwei just got out of the car and went straight to the security room.
"Uncle, which building does Han Dewen live in?" Lu Weiwei opened the screen window and asked directly an old man who was blowing a fan.
"Han Dewen? Principal Han?" Upon hearing this, the uncle quickly sat up straight: "He lives in Building 3, it seems...Room 1102."
"Do you even remember the room number in his house?" Officer Wang was surprised.
In general, it is not easy for security guards in a community to remember which building a resident lives in, but those who can remember house numbers are probably very rare.
What's more, the number of residents in this community is at least a thousand or more. An old man in his 60s or 70s can kill 95% of the security guards in the city instantly by just opening his mouth.
"I have been working here for almost 20 years. I don't know what is going on with each family. Not to mention which family lives in which number, I know all their occupations. Those who live in this community are either rich people or leaders. Who are they?
I can’t afford to offend you. If I don’t act smarter, how can I stay here for 20 years?”
"You must have gained a lot of benefits in the past 20 years, right?" Looking at the old man's glib expression, Gu Chen knew, was the old man guarding the door? People guard relationships.
The old man grinned: "As expected of a comrade in the police force, he is a sensible person at first glance."
Gu Chen shook his head and continued to ask him: "Which are those three buildings?"
"This is the building over here."
"Thanks."
After understanding the situation, Gu Chen took everyone directly to Room 1102, Building 3.
Arriving at the door, Yuan Shasha rang the doorbell first.
Not long after, I heard a small figure wearing slippers, running to the door.
The door opened, and a little boy tilted his head and looked at everyone: "Huh? Brother policeman? Why is it you?"
"Liangliang?" Gu Chen looked at the little boy and suddenly remembered the blood draw. His eyes suddenly froze and he quickly asked him: "Is Han Dewen your father?"
"Yes, my name is Han Liang, and my dad's name is Han Dewen."
"Then is he at home?" Lu Weiwei asked.
Liangliang turned to look at the toilet, then turned back cutely and said: "He is in the toilet."
"What about mom?"
"Mom went out to buy soy sauce."
Lu Weiwei: "..."
"Okay, I'm just going to find your father and ask him to come out, okay?" Lu Weiwei said with a bit of a headache.
Liangliang was a sensible child, so she immediately ran to the bathroom door and banged the door twice: "Dad, come out quickly, someone is looking for you."
Looking at Liangliang's innocent look, it was really hard for Gu Chen to imagine that when Han Dewen was in the interrogation room, he also said that he and his wife were divorcing and that his son would belong to his wife.
But now, in the blink of an eye, isn’t this family a good family?
Moreover, according to the staff at the blood station, Liangliang's father was just on a business trip, but when Gu Chen found him, Han Dewen was entertaining friends at KTV.
It can be seen that Han Dewen has the ability to tell lies.
"Who is it?"
As the sound of flushing came from the toilet, Han Dewen walked out of the toilet.
When he saw Gu Chen at the door, Han Dewen's face froze, and he suddenly forced a smile and said, "Oh! Who do I think you are? It turns out to be Police Officer Gu, what? What are you doing?"
"Come with us." Gu Chen said.
Han Dewen glanced at Liangliang and felt a little embarrassed: "This... this child is at home alone."
"It's okay, mom will be home soon." Liangliang said.
In one sentence, Han Dewen's excuses were completely blocked.
Han Dewen's face became even uglier, otherwise he would say that your unlucky child is cheating on his father.
Unable to see clearly, Han Dewen could only push up his glasses and reluctantly agreed: "Okay, I'll go with you."
He glanced at Liangliang and said, "Is it okay for Liangliang to be alone at home?"
"Okay." Xiao Liangliang had no idea where the police wanted to take his father.
In my impression, all kinds of people came to see my father at home, either to invite him to drink or to have dinner. Liangliang was already used to it.
But no matter what kind of person he was, no police came to his door.
But this time, Liangliang finally found the policeman brother she had longed for. She felt that it would be very interesting for her father to be called away.
"boom!"
The door was closed, and Han Dewen, wearing slippers, was taken away directly by Gu Chen and headed to the interrogation room of Furong Branch.
…
…
Interrogation Room No. 1.
Han Dewen looked even more embarrassed when he looked at the familiar surroundings.
I entered the interrogation room of the police station twice in one day, and thinking about it, there was no one there.
He looked up at Gu Chen and said with some confusion: "Officer Gu, what do you want from me?"
"It's not a good thing anyway." Gu Chen said.
Han Dewen:???
Is it so direct?
"Then just say it."
I feel like I have no patience anymore. I was about to say something in the car just now, but I hesitated. I felt that the atmosphere in the car was depressing and not suitable for talking about heavy topics.
"Did you know that Wan Yajuan died of suffocation?" Gu Chen asked him directly.
Han Dewen's eyes widened: "Wha...what? Wan Yajuan is dead? This...is this impossible? How is this possible?"
"Nothing is impossible." Lu Weiwei cooperated with Gu Chen and also answered: "When we sent Zhu Huaiping's parents to his house, we found Wan Yajuan in the room, suffocated to death. The murderer should be you, right?"
"This...how is this me?" Feeling that he had been wronged, Han Dewen quickly denied it: "This is definitely not me."
"It's not you. Why did you go to her house? Her husband just died, and you can't wait so hard?" Officer Wang has always disliked Han Dewen, and he also spoke with obvious personal emotions.
In his opinion, Han Dewen should have been punished in the last interrogation. Fortunately, he was able to speak eloquently at that time, but there was insufficient evidence on his side.
The only option is to let him go first and then settle the score.
But retribution is retribution after all.
After a while, Officer Wang was able to take Han Dewen back to the police station.
This was undoubtedly a slap in the face to Han Dewen.
Han Dewen smiled bitterly and said: "Comrade police, I don't know what you are going to say? I just heard that Wan Yajuan's husband passed away. Thinking about it, she must be in pain now. After all, we have feelings for each other, so I thought about it.
Look at her, I'm afraid she won't be able to think about it."
"I'm afraid she won't be able to think about it, so you gave her sleeping pills?" Gu Chen said one sentence, and instantly dismissed Han Dewen's remarks.
Han Dewen's face was stiff at this moment. He looked around helplessly and smiled bitterly: "Comrade police, look at what you said, why do you want me to give her sleeping pills?"
"You don't need to explain. Did Wan Yajuan drink water containing sleeping pills? Do you think our police don't know that? Are you underestimating our police's detection methods?" Lu Weiwei also said seriously.
Han Dewen quickly waved his hand: "No, no, that's not what I meant. What I meant was that she might have drank the sleeping pills herself."
"But there are no sleeping pills in her room, and there is no cup for water. Who could have taken it away if you hadn't?" Lu Weiwei stared at him with sharp eyes.
Han Dewen was stunned for a moment before he realized what he was doing. He immediately smiled and said, "Then I don't know even more. How do I know? I just went to see her and then left."
"Hmph!" Gu Chen snorted coldly, turned his pen with his right hand and said: "Okay Han Dewen, we won't tease you anymore. I can tell you clearly that Wan Yajuan is not dead, and she did not take the initiative to drink.
Take sleeping pills.”
"And when we were in the room, you, Han Dewen, were the only one present. If it wasn't you who did it, who else could be there?"
"Ah? Not... not dead?" Just hearing the news that Wan Yajuan died of suffocation, Han Dewen almost laughed like a pig in his heart.
But now that Gu Chen said he was not dead, the questions of true and false were raised one after another, making it difficult for Han Dewen to tell what was true and what was false?
"You don't believe it?" Gu Chen asked him.
Han Dewen tried his best to pat his chest and said with a wry smile: "Comrade police, please don't scare me."
"I didn't scare you. Fortunately, we arrived in time and saved Wan Yajuan's life. However, we learned from her mouth that she started to feel sleepy after drinking the glass of water you poured for her.
As for how she ended up lying on the bed later, she herself doesn’t quite know.”
"But one thing is certain, that is, you were always by her side before she went to bed, so all the decorations in her room should be your masterpiece, right?"
"This..." Han Dewen felt a little guilty, but he said bluntly: "Just say what you want to say?"
"You used your knowledge of physics to murder Wan Yajuan in real time. The two parallel electric fans are the best proof." Gu Chen said.
"Haha, electric fan?" Han Dewen couldn't help laughing, feeling that Gu Chen was telling him a joke.
"Comrade police, are you deliberately picking on me? Yes, I turned on the electric fan, and Wan Yajuan was indeed a little sleepy at the time. I asked her to go to bed to rest. I was afraid that she would be hot, so I turned on the two electric fans.
fan."
"You are really capable." Listening to Han Dewen's own story, Gu Chen didn't beat around the bush.
"As a top student in physics, you should know Bernoulli's principle, right? The greater the speed of the fluid, the lower the pressure of the fluid."
Han Dewen was stunned and lowered his head slightly: "No... yes, I know."
"Then you should also know that when two fans are parallel and blow in one direction, an air pressure will be formed in the middle."
"The high-speed airflow prevents outside air from coming in, so the air in the middle area is reduced. Wan Yajuan was in deep sleep because she took sleeping pills, so she couldn't wake up at all."
"So when two fans blow towards her, it will put her in danger of suffocation and death. I don't need to remind her of this, right?" Gu Chen asked again.
Hearing Gu Chen's words, Han Dewen was completely panicked.
He didn't expect that a young policeman who looked ordinary would have such an amazing reserve of knowledge.
He also didn't expect that Gu Chen not only knew Bernoulli's principle, but also knew that when two fans are parallel and blow in one direction, an air pressure will be formed in the middle.
These things should not be in the hands of the police, but Gu Chen showed them one by one.
At this moment, Han Dewen was like a swimmer who had his underwear stripped off, with no secrets left in his body.
Seeing that Han Dewen was a little panicked, Gu Chen continued: "According to Bernoulli's principle, the greater the speed of the fluid, the lower the pressure of the fluid."
"And two parallel electric fans are blowing towards the sleeping Wan Yajuan. The pressure in the place where the electric fans blow is low. People in places with low pressure naturally cannot breathe normally. The main reason is that they cannot inhale, so they will
Causing suffocation."
"Because the principle is very simple, because inhalation requires the external atmospheric pressure to be greater than the air pressure in the chest, so that external oxygen can enter the human body and ensure the normal survival of the human body."
"And you made good use of these two electric fans at that time, which caused Wan Yajuan to be unable to breathe."
"I..." Han Dewen was about to speak, but he hesitated for a moment. He didn't know how to defend himself.
The main reason is that I don’t know what to defend.
Gu Chen knew what he wanted to say, so he explained all the key clues one by one: "You know, when people feel uncomfortable, they will resist."
"Because once this operation lasts too long, Wan Yajuan's various organs will be exhausted and she will feel uncomfortable all over."
"The air flow velocity in her location is very high, and according to Bernoulli's principle, the atmospheric pressure will decrease. When it decreases to approximately equal to the air pressure in the human chest, very little oxygen will enter the human body, so it is easy to cause suffocation."
"So in order to achieve your goal, you made her take sleeping pills so that she could not wake up when she was uncomfortable, thus achieving your goal of killing."
"You want Wan Yajuan to suffocate to death in the room without knowing it, thus leaving you with an alibi proving that you had nothing to do with Wan Yajuan's death."
Looking at Han Dewen's desperate eyes, Gu Chen said again: "But you didn't calculate that our police would arrive with Zhu Huaiping's parents. You thought Wan Yajuan's body might be found in a few days or a week.
If you are discovered, your alibi may be more sufficient at this time."

"Officer Gu, I... I must be unjust." Han Dewen didn't know how to defend himself, so he could only sit back and remain stubborn at the end.
Before Gu Chen could say anything, Lu Weiwei beside him said directly: "Let's not talk about it for now. You encouraged Wan Yajuan to kill Zhu Huaiping, so what's the point?"
"Wha...what? I encouraged Wan Yajuan to kill Zhu Huaiping? Haha."
Listening to Lu Weiwei's words, Han Dewen finally breathed a sigh of relief and laughed and said: "Comrade police, you are making false accusations. Everyone knows that Zhu Huaiping drove dangerously on his own initiative. He has suicidal tendencies and he wants to kill him."
That carload of people.”
"But later, he had a chance to escape with his life, but he jumped to commit suicide in front of your eyes. You all know this, but I was not there at the time."
"That's it, you still say that I instigated the murder? Haha, I don't know what courage you have to say that?"
"Benzodiazepines and barbiturates, do they sound familiar?" Gu Chen said.
Han Dewen was stunned, and the way he looked at Gu Chen changed.
"If it's not clear, let me tell you two more. You know about diazepam tablets and alprazolam tablets, right? Aren't these the prescription drugs that you asked Wan Yajuan to pretend to be sick and prescribed from the doctor?"
"Furthermore, Wan Yajuan has already given all this information, and in accordance with your requirements and instructions, Zhu Huaiping was allowed to take it for a long time without his knowledge."
Seeing that Han Dewen was stunned and stunned, Gu Chen also said bluntly: "Zhu Huaiping suffers from depression. From the mild depression at the beginning to the extreme suicide later, you actually played a role in fueling the situation."
"As a top science student at a prestigious university, you don't know that patients with depression cannot take these drugs at all, right? It will prompt patients with depression to, at certain moments, radically implement some ideas that they once dared not implement."
"Because these tranquilizers and sedatives have a reputation for causing depression and exacerbating it."
"What you did was just to kill Zhu Huaiping."
Listening to Gu Chen's stern scolding, Han Dewen was completely stunned.
He looked at Gu Chen with a pale face, his eyes full of panic.
Officer Wang couldn't stand it anymore and shouted angrily: "I have never seen such a cruel guy like you. On the surface, Zhu Huaiping's death and Wan Yajuan's almost suffocation death seem to have nothing to do with you.
This incident was actually all planned by you behind the scenes."
"If we hadn't woken up Wan Yajuan in time, she might still not be able to believe that you actually wanted to kill her with your own hands. You are really a devil."
"Not only is he a devil, he is also a scumbag." Lu Weiwei couldn't help complaining.
The interrogation atmosphere at the scene suddenly became tense.
The light shone on Han Dewen's face, making him look particularly terrifying.
A smooth-mannered high school vice-principal suddenly transformed into a demon with a human face and a beastly heart. This was beyond anyone's imagination.
Han Dewen's psychological defense collapsed. He knew that as long as Wan Yajuan was still alive, he would definitely not be able to escape.
Wan Yajuan didn't die this time, which meant that all the plans she had worked so hard to implement collapsed overnight.
"Haha." Han Dewen sneered twice and rubbed his back hard. He was going crazy and unwilling to give up.
Soon, Han Dewen's hair began to become messy.
He looked up at Gu Chen and said with a sneer: "I thought I was a master of time management and could walk among women. It seems that I was wrong, and it was a big mistake. I was ruined in the hands of women after all.
"
"Why did you kill Wan Yajuan?" Gu Chen turned his pen with his right hand and asked him.
"Because she really wants to marry me." Han Dewen said.
Lu Weiwei frowned slightly: "Isn't that what you want?"
"No." Han Dewen shook his head: "I was just talking, but Wan Yajuan took it seriously. I love my wife very much and my children very much. I lied to Wan Yajuan. I was just greedy for her body.
I have never thought about divorcing and staying with her."
"Because I am the vice-principal of No. 6 Middle School, so I can be considered a public figure, right? The divorce will have a huge impact on my future, and I can't bear it."
"Everything I have today is the result of my hard work. I can't afford to lose. I will never divorce for Wan Yajuan."
"Then what about the medicines you encouraged her to prescribe to Zhu Huaiping?" Lu Weiwei asked.
Han Dewen snorted coldly: "I was just talking casually, but I didn't expect that woman to take it seriously."
