I am a super cop

Chapter 919 Devil
8:20pm.

Outside a high-end residential area, Gu Chen, Officer Wang and Lu Weiwei found the security room as soon as they got out of the car.

"Master, which building does Han Dewen live in?" Lu Weiwei pushed open the screen window and directly asked an old man who was blowing a fan.

"Han Dewen? Principal Han?" Hearing this, the uncle hurriedly sat up straight: "He lives in Building 3, it seems to be... Room 1102."

"Do you even remember the number of his house?" Officer Wang was surprised.

It is not easy for the security guards in the general community to remember which building the residents live in, but it is probably rare for security guards who can remember the house number.

What's more, there are at least a thousand households in this community. An old man in his 95s and [-]s can come here as soon as he opens his mouth. He feels that he can instantly kill [-]% of the security guards in the same city.

"I've been working here for almost 20 years. I don't know who's what. Don't say who lives in which number, I know what kind of job they have. Those who live in this community are either rich or leaders. Who I can’t afford to be offended, if I’m not smart enough, I can do it for 20 years and not leave?”

"Presumably in the past 20 years, you should have received a lot of benefits, right?" Looking at the old man's slick tongue, Gu Chen knew, was the old man guarding the gate?What people keep is relationship.

The old man grinned: "As expected of a comrade police officer, you can see that you understand."

Gu Chen shook his head, and continued to ask him: "Which are those three buildings?"

"This building is here."

"Thank you."

After understanding the situation, Gu Chen directly led everyone to Room 3, Building 1102.

When she came to the door, Yuan Shasha rang the doorbell first.

Not long after, I heard a small step in slippers running towards the door.

The door opened, and a little boy tilted his head to look at everyone: "Huh? Police brother? Why are you?"

"Liangliang?" Gu Chen looked at the little boy and suddenly remembered the matter of drawing blood. His eyes froze for a moment, and he quickly asked him, "Is Han Dewen your father?"

"Yes, my name is Han Liang, and my father's name is Han Dewen."

"Then is he at home?" Lu Weiwei asked.

Liangliang turned her head to look at the toilet, then turned around and said cutely: "He's in the toilet."

"What about mom?"

"Mom went out to buy soy sauce."

Lu Weiwei: "..."

"Okay, I'm only looking for your father, can you tell him to come out?" Lu Weiwei said with a nod.

Liangliang was a sensible child, so he ran to the toilet door and slammed the door twice: "Dad, come out quickly, someone is looking for you."

Looking at Liangliang's innocent appearance, 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 a blink of an eye, isn't this family all right?

Moreover, according to the staff at the blood station, Liangliang's father was only on a business trip, but when Gu Chen found him, Han Dewen was having fun with his friends at the KTV.

It can be seen that with this ability to talk nonsense, Han Dewen just opened his mouth.

"Who is it?"

With the sound of flushing 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, "Hey! Who do I think it is? It turned out to be Police Officer Gu. What's the matter?"

"Come with us." Gu Chen said.

Han Dewen looked brightly, a little embarrassed: "This... this child is at home alone."

"It's okay, mom will be home soon." Liangliang said.

In a word, Han Dewen's excuse of evasion was directly blocked.

Han Dewen's face became even more ugly, otherwise you would say that you are an unlucky child cheating on you.

Seeing that he couldn't go, Han Dewen could only push his glasses, and reluctantly agreed, "That's fine, I'll go with you."

He glanced at Liangliang, and said again: "Is Liangliang at home alone?"

"Okay." Xiao Liangliang had no idea where the police were going to take his father.

In my impression, all kinds of people come to see Dad at home, either for a drink or a meal, and Liangliang has long been used to it.

But no matter what kind of person it is, only the police did not come to the door.

But this time, Liangliang finally looked forward to the policeman brother he had been thinking about, and felt that his father was called away, which must be very interesting.

"boom!"

The door was closed, and Han Dewen, who was wearing slippers, was directly taken away by Gu Chen and went to the interrogation room of Furong Branch.

……

……

Interrogation Room [-].

Looking at the familiar environment around him, Han Dewen looked even more embarrassed.

In this day, I entered the interrogation room of the police station twice. Thinking about it, there was no one there.

He looked up at Gu Chen, a little puzzled and said, "Officer Gu, what are you looking for me for?"

"Anyway, it's not a good thing." Gu Chen said.

Han Dewen:? ? ?

Is it so direct?
"Then just say it."

I feel that I am impatient. I wanted to talk in the car just now, but I stopped talking. I feel that the atmosphere in the car is depressing and it is not suitable for talking about some heavy topics.

"Do you know that Wan Yajuan suffocated to death?" Gu Chen asked him directly.

Han Dewen stared: "What... what? Wan Yajuan is dead? This... is this impossible? How is this possible?"

"Nothing is impossible." Lu Weiwei cooperated with Gu Chen and continued, "When we sent Zhu Huaiping's parents to his house, we found Wan Yajuan in the room, who had suffocated to death. You should be the murderer, right?"

"This... how can this be me?" Feeling wronged, Han Dewen quickly denied it: "This is definitely not me."

"It's not you, what are you going to her house for? She just lost her husband, so you can't wait?" Officer Wang has always disliked Han Dewen, and he spoke with obvious personal emotions.

In his opinion, Han Dewen should have been allowed to obey the law in the last interrogation, but fortunately he was eloquent at that time, and his own evidence was insufficient.

The only choice 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 bring Han Dewen back to the police station.

This undoubtedly gave Han Dewen a slap in the face.

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 great pain now. After all, we have feelings, so I just want to pass away." Look at her, I'm afraid she won't think about it."

"I'm afraid she won't be able to think about it, so you gave her sleeping pills?" With one sentence, Gu Chen immediately dismissed Han Dewen's words.

Han Dewen's face was stiff at the moment, he looked around helplessly, and said with a wry smile: "Comrade policeman, look at what you said, why should I give her sleeping pills?"

"You don't need to explain. Did Wan Yajuan drink water containing sleeping pills? You think we police don't know? Are you underestimating our police detection methods?" Lu Weiwei also said seriously.

Han Dewen quickly waved his hand: "No, no, that's not what I meant. What I mean is that she might have taken the sleeping pills herself."

"But she didn't have sleeping pills in her room, nor did she have a cup of water. Who would it be if you didn't take it away?" Lu Weiwei stared at him sharply.

Han Dewen was stunned for a while, and then he realized it, and said with a smile: "Then I don't know, how do I know? I just went to see her and then left."

"Hmph!" Gu Chen snorted coldly, and turned the pen with his right hand to prompt: "Well, Han Dewen, we won't tease you anymore, I can tell you very clearly that Wan Yajuan is not dead, and she didn't take the initiative to drink Take sleeping pills."

"And when you were in the room, you, Han Dewen, were the only one present. Who else would have done it if you hadn't done it?"

"Ah? No... not dead?" Hearing the news of Wan Yajuan's suffocation just now, Han Dewen almost laughed out loud in his heart.

But now that Gu Chen said he was not dead, the question of true and false was raised one after another, making it difficult for Han Dewen to distinguish what is true and what is false?
"You don't believe it?" Gu Chen asked him.

Han Dewen patted his chest hard, and said with a wry smile: "I said comrade policeman, don't scare me."

"I didn't scare you. Fortunately, we arrived in time and saved Wan Yajuan's life. However, I learned from her that she started to feel sleepy after drinking the glass of water you poured her. As for how she ended up lying on the bed, she herself didn't quite know."

"But one thing is certain, that is, you were always by her side before she went to bed, so all the arrangements in her room should be your masterpiece, right?"

"This..." Han Dewen was a little guilty, but he said bluntly: "You can say whatever you want?"

"You used your knowledge of physics to murder Wan Yajuan in real time, and those two parallel electric fans are the best proof." Gu Chen said.

"Hehe, electric fan?" Han Dewen couldn't help laughing twice, feeling that Gu Chen was joking with him.

"Comrade police, are you trying to find fault with me? That's right, I turned on the electric fan, and Wan Yajuan was really sleepy at the time. I put her to bed and rested. I was afraid that she would be hot, so I turned on two electric fans. fan."

"You are really good enough." Listening to Han Dewen's own narration, Gu Chen didn't play tricks with him.

"You, a talented student of physics, should know Bernoulli's principle? The greater the velocity 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 blowing in one direction, an air pressure will be formed in the middle."

"And the high-speed airflow prevents the outside air from entering, so the air in the middle area decreases, and because Wan Yajuan took sleeping pills and fell into a deep sleep, she couldn't wake up at all."

"So when two fans blow on her, it will cause her to suffocate to death, so I don't need to remind you?" Gu Chen asked again.

Hearing Gu Chen's remarks, Han Dewen was completely panicked.

He did not expect that an ordinary-looking young policeman had such an amazing reserve of knowledge.

He didn't even expect that Gu Chen not only knew Bernoulli's principle, but also knew that when two fans are parallel and blowing in one direction, an air pressure will be formed in the middle.

These things should not be grasped by the police, but they are displayed here one by one by Gu Chen.

At this moment, Han Dewen is like a swimmer whose underwear has been stripped off, with no secrets at all.

Seeing Han Dewen panicked, Gu Chen continued: "According to Bernoulli's principle, the greater the velocity of the fluid, the lower the pressure of the fluid."

"The two parallel electric fans are blowing air on Wan Yajuan who is sleeping. The place where the electric fan blows is low in pressure. People in places with low pressure will naturally be unable to breathe normally. The main reason is that they cannot inhale. cause suffocation."

"Because the principle is very simple, because inhalation requires the external atmospheric pressure to be greater than the air pressure in the chest cavity, so that the 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 made Wan Yajuan unable to breathe."

"I..." Han Dewen was about to speak, but he hesitated for a moment. He didn't know how to defend himself.

Mainly because I don't know what to justify.

Gu Chen knew what he wanted to say, so he explained all the key clues one by one: "You know, people will resist when they are uncomfortable."

"Because once this operation takes too long, Wan Yajuan's various organs will be exhausted, and she will feel uncomfortable all over her body."

"And the air velocity at her location is very high, and according to Bernoulli's principle, the atmospheric pressure will decrease. When it is reduced to approximately equal to the human chest pressure, the oxygen entering the human body will be very little, so it is easy to cause suffocation."

"So in order to achieve your goal, you let her take sleeping pills, so that she can't wake up when she is uncomfortable, so you can achieve your goal of killing people."

"You want Wan Yajuan to suffocate to death in the room without knowing it, so as to leave you an alibi to prove that you have nothing to do with Wan Yajuan's death."

Looking at Han Dewen's desperate eyes, Gu Chen said again: "But you have calculated thousands of times. You didn't calculate that our police would bring Zhu Huaiping's parents to arrive. Do you think that Wan Yajuan's body may be found in a few days or a week? If you are discovered, at this time, your alibi may be more sufficient."

"But unfortunately, it seems that God doesn't want to help you."

"Officer Gu, I...I must have been wronged." Han Dewen didn't know how to defend himself, so he could only sit with his last stubbornness.

Before Gu Chen could speak, Lu Weiwei who was beside her said directly, "Let's not talk about this, you encouraged Wan Yajuan to kill Zhu Huaiping, so what's the matter?"

"What... what? I encouraged Wan Yajuan to kill Zhu Huaiping? Hehe."

Hearing Lu Weiwei's words, Han Dewen finally breathed a sigh of relief, and said with a big smile, "I said, comrade police, you are framing. Everyone knows that Zhu Huaiping took the initiative to drive dangerously. He has suicidal tendencies. He wants to kill him." The people in that car."

"But later, he narrowly escaped his life, but he committed suicide by jumping off a building right under your noses. You all know this, and I wasn't there at the time."

"That's it, you still say that I instigated the murder? Hehe, I don't know what courage you have to say that?"

"Benzodiazepines and barbiturates, don't they sound familiar?" Gu Chen said.

When Han Dewen was stunned, the way he looked at Gu Chen changed.

"If you don't know, then I'll say two more. You know about diazepam tablets and alprazolam tablets, right? Aren't these all prescription drugs that you asked Wan Yajuan to pretend to be sick from the doctor?"

"Furthermore, Wan Yajuan has already given all this information, and according to your request and instructions, Zhu Huaiping was allowed to take it for a long time without knowing it."

Seeing that Han Dewen was so frightened, Gu Chen also said bluntly: "Zhu Huaiping suffered from depression. From the mild depression at the beginning to the violent suicide later, you all played a role in fueling the flames."

"As a top science student in a prestigious school, you don't know that patients with depression can't take these drugs at all, right? It will prompt patients with depression to, at certain moments, aggressively execute some ideas that they never dared to execute."

"Because these sedatives and sedatives have a notorious reputation for triggering depression and exacerbating illness."

"You did this because you wanted to kill Zhu Huaiping."

Hearing Gu Chen's stern words, Han Dewen was stunned.

He looked at Gu Chen with a dead face, his eyes full of panic.

Police Officer Wang couldn't stand it anymore, and directly shouted angrily: "I've never seen such a cruel guy like you. On the surface, Zhu Huaiping's death, and Wan Yajuan's almost suffocated death, these seem to have nothing to do with you The incident was actually planned by you behind the scenes."

"If we hadn't made Wan Yajuan wake up in time, maybe up to now, she can't believe that you want to kill her with your own hands, you are really a devil."

"It's not just a demon, it's a scum." Lu Weiwei couldn't help but complain.

The interrogation atmosphere at the scene suddenly became tense.

The light hit Han Dewen's face, making him look extraordinarily terrifying.

A gentle high school vice principal suddenly transformed into a monster with a face of beasts, which was unimaginable to everyone.

Han Dewen's psychological defense collapsed. He knew that as long as Wan Yajuan was still alive, he would not be able to escape.

Wan Yajuan didn't die this time, which meant that the various plans she had painstakingly implemented collapsed overnight.

"Haha." Han Dewen sneered twice, he rubbed his back hard, he was mad, he was unwilling.

Soon, Han Dewen's hairstyle became messy.

He looked up at Gu Chen, and said with a sneer: "I thought I was a master of time management, able to walk among women, but it seems that I was wrong, and it was a big mistake, I will still be ruined by women after all. "

"Why did you kill Wan Yajuan?" Gu Chen asked him, turning the pen with his right hand.

"Because she really wants to marry me." Han Dewen said.

Lu Weiwei frowned slightly: "Isn't that what you wished for?"

"No." Han Dewen shook his head: "I was just talking, but Wan Yajuan took it seriously. I love my wife and my child very much. I lied to Wan Yajuan. I just wanted her body. I never thought about getting a divorce and being with her."

"Because I'm the vice principal of No. [-] Middle School, so I can be regarded as a public figure after all, right? Divorce has dealt too much blow to my future, and I can't bear it."

"And everything I have today is due to my hard work. I can't afford to lose. I will never divorce for Wan Yajuan."

"Then what about the medicine you encouraged her to prescribe for Zhu Huaiping?" Lu Weiwei asked.

Han Dewen snorted twice: "I was just talking casually, but I didn't expect that woman to take it seriously."
