Controlled experiment

Du Yusheng chewed the rice but did not swallow it, he looked at Li Yao in disbelief.

Asked again: "What did you say?"

"I said that when Gu Qingyu entered, Chen Xin should have died."

Du Yusheng looked at the simple drawings that Li Yao had sent over.Most people who study medicine can draw pictures, such as anatomical atlas and human body structure. They are the best. Although there are only simple rules and regulations, Chen Xin's ward is still easily restored by Li Yao.The position of the door was circled by Li Yao, and the position of the vent was also circled.

Li Yao didn't speak, but Du Yusheng understood.

"You mean to say that there were two people in Chen Xin's ward."

Li Yao nodded, pointed to the two circles on the drawing and said: "My idea is this, first of all, the first person entered Chen Xin's ward from my office, and lit the incense in the vent, and then this person Come out from the vent and kill Chen Xin. Immediately afterwards, a second person appeared, he entered Chen Xin's ward wearing my clothes, and he found Chen Xin dead, so he left without doing anything. If Two people entered Chen Xin's ward one after another, which one do you think is Gu Qingyu."

Du Yusheng rubbed his fingers and replied, "The second one."

"Why?" Li Yao asked.

"It's very simple. From the surveillance video, Gu Qingyu has clearly been to the hospital, but just now he lied to me that he hadn't been there. If Chen Xin was still alive when he entered the ward, he could have told me the truth just now, saying that he went to the hospital." I went to the hospital and met Chen Xin, but he didn't do that."

Du Yusheng took a sip of the water on the table.

If the murderer could kill Chen Xin through the vent, then he wouldn't enter the ward again from the door in someone else's white coat, which seemed unnecessary.If you think this way, Li Yao is right. That night, there were two people in Chen Xin's ward.According to inference, Gu Qingyu should have entered after Chen Xin's death.

"So, either Chen Xin was already dead when Gu Qingyu entered." Du Yusheng touched his chin, and said, "Either, Gu Qingyu killed Chen Xin."

Li Yao nodded, the corners of his mouth slightly raised.

"Have you checked Chen Xin's house?"

Du Yusheng sneered, and shook his head helplessly, "Do you know how tough his wife is? She still insists on the hospital and refuses to let us check his home, but my colleague has done ideological work and made the final decision." Notice, if you don’t cooperate with the inspection, it will be enforced.”

Li Yao smiled and said nothing more.

The brunch was good, but Li Yao was not good at cooking, so he seldom ate well.

After simply tidying up the dishes on the table, Li Yao rolled up his cuffs and turned on the faucet, bent down, and looked for the bottle of detergent he bought last month in the cabinet.The washing spirit was bought as a gift, Li Yao never used it, and a layer of dust fell on the bottle cap.

Li Yao took a deep breath and was about to open it, but someone grabbed his wrist suddenly.

"What are you doing?" Du Yusheng stopped his movement, raised his hands, and said with a smile, "I'll come. Cooking and washing dishes are the same thing. They can't be separated."

Li Yao was a little embarrassed, but Du Yusheng didn't mean to let him touch the water at all, so Li Yao decided to give up after thinking about it.

After wiping his fingers with a few paper towels on the table, Li Yao leaned on the table and looked at the back of Du Yusheng washing the dishes.

The decoration of Li Yao's house was done according to the pictures, without considering the owner's height, so the cabinet above the sink was installed too low, and Du Yusheng hunched over while washing dishes, looking uncomfortable.Li Yao suddenly had an idea of ​​wanting to replace the kitchen cabinet, Li Yao himself was startled by this thought.

Du Yusheng was probably afraid of the cold, and he was wearing a small vest under his jacket. Not only could the outline of his clothes be seen clearly, but even his large muscles could be seen with his hunched back.Deltoids, teres minor, teres major, latissimus dorsi, external obliques, and gluteus maximus at the bottom.Li Yao looked at Du Yusheng's back, and drew the position of several muscles on his body bit by bit in his mind.

This is a job that requires patience, Li Yao turned his face away, took a glass of cold water and fed it to himself.

"By the way, has the cause of Chen Xin's death been revealed?" Li Yao asked to divert his attention.

"It should be soon." Du Yusheng's muffled voice came from the other side, and said, "I thought of something here. Guess what Chen Xin found in his stomach?"

The sound of the faucet on Du Yusheng's side was very loud, and it was the second time that Li Yao heard his words clearly.

"Controlled experiment."

Li Yao was stunned.

"Isn't this what was found in Daheng Luo's stomach?"

"You reacted the same as I did."

Du Yusheng washed the bowls and arranged them in the cupboard according to their size, and said, "So I still have to meet Luo Yang, Chen Xin is dead, and there is no time to interrogate him for such a thing, but in fact there is no need to interrogate him again, the evidence is solid , directly dragged it out to make a decisive decision, but something exactly like Luo Daheng appeared in Chen Xin's stomach, so I have to ask."

After finishing speaking, Du Yusheng sat on the sofa and sighed deeply.

"Hey, you said that if Luo Yang can't ask anything here, what should I do?"

In addition to ridicule in his words, Li Yao could hear a little sadness.Probably this sentence was also for Du Yusheng himself.

Du Yusheng sank his face deeply into the sofa, making a muffled sound.

Before leaving, Du Yusheng wanted to say goodbye to Li Yao, but he didn't expect to go to the restroom and come out, Li Yao stood at the entrance fully dressed and changed his shoes.

Du Yusheng frowned, smiled, and said, "Are you going out?"

Li Yao nodded inside, and said, "Aren't you going to the police station to interrogate Luo Yang? It just so happens that I have something to go to the Huandao branch, so I'll drop by."

Du Yusheng opened his mouth, and it took him a long time to say "ah?", and he asked belatedly, "what's the matter?"

Li Yao smiled, with a gentle and polite look, and said, "Private matters are all private matters."

In the past, if Li Yao could ask Du Yusheng to do something together one day, Du Yusheng would be happy for a few minutes and take a car ride along the way. Although it was a trivial matter, Du Yusheng never thought about it. I am happy, but I always feel twisted.Can't tell what's wrong.

He wanted to know what Li Yao was going to do when he went to the police station.

If you can't ask, you can't ask.

Taking advantage of the red light, Du Yusheng looked at Li Yao who was sitting in the co-pilot. The latter was feigning sleep with his eyes closed. Du Yusheng hummed softly, thinking that he should focus on the case.

After entering the Huandao sub-office, he said goodbye to Du Yusheng, and Li Yao went up to the second floor.

Half of the second floor was occupied by those leaders' offices. Du Yusheng frowned as he watched Li Yao disappear at the end.

He suddenly had a bad feeling.

A feeling of being tricked.

==

It has been a long time since I last met Luo Yang in the toilet of the airport.

As Du Yusheng said, if there were no doubts, Du Yusheng would not have any further communication with Luo Yang. Not because of a controlled experiment, maybe really never see you again.

Luo Yang is a little different from the last time we met.

He was wearing a gray uniform and wearing elegant glasses. He didn't seem to have slept well. His mental state and improvement were not as good as before, and there were some bruises on the parts exposed outside the clothes.

Luo Yang yawned and greeted Du Yusheng with a smile.

The bruising on his temples and the swelling at the corners of his mouth were too eye-catching, so Du Yusheng asked his colleagues next to him.

"Hey, you also know that there are people here who are good at that. Luo Yang looks fair and clean. Those people like Luo Yang who looks arrogant... We are the key caretakers, so we can't keep an eye on him 24 hours a day. , Do you think so, we can't prevent it."

Knowing that Luo Yang on the opposite side couldn't hear him, Du Yusheng touched his nose sensitively.

Asked: "Then... have you eaten?"

The person over there shook his head, sneered, and said, "Luo Yang drained his blood, and left him in the men's bathroom all night. When we gathered in the morning, he found out that the man almost died."

Du Yusheng glanced at Luo Yang and felt chills all over.

After calling people out, Du Yusheng walked across to Luo Yang and looked at him.

It was only after a closer look that Luo Yang became a little thinner.He looked like he would never win a fight, and Du Yusheng was really curious about how he bled him out.

"Officer Du." Luo Yang lowered his head, smiled and said, "We haven't seen each other for a long time."

Du Yusheng didn't know what to say, so he could only nod his head, and slammed right across from Luo Yang.

"At first I didn't want to come again. Your case has solid evidence and there is no chance of turning over, but I heard that you have hired a lawyer." Du Yusheng licked his lips and continued: "Why did you kill your father. "

Luo Yang thought for a while, and said in an unusually flat manner: "There is no reason, I just thought about it."

His expression was unexpectedly calm, without any waves. Within a few seconds, Du Yusheng thought he had heard it wrong.

Luo Yang's appearance is as if he is greeting you and chatting with you, which is so commonplace.

"What do you mean by thinking about it?" Du Yusheng couldn't help but raise his voice and said, "That's your father."

Luo Yang suddenly laughed, and asked:

"Officer Du, are you eating?"

Du Yusheng didn't speak.

"Then why do you want to eat?" Luo Yang smiled and said, "You ask me why I killed him, it's the same as asking me why I want to eat, you just think about it, there is no reason. I am his illegitimate child, what kind of relationship can we have? He just needs a son, and I happen to be that one."

This answer was a bit novel, and Du Yu was convinced.It is impossible to delusional understanding of a perverted mind.

Du Yusheng patted the table.

"You stuffed the note in Daheng Luo's stomach?" He said, "What do you mean by the words 'control experiment'? Don't tell me, you just found four words and stuffed them in."

Luo Yang's hands were handcuffed, making it difficult to move. He lowered his head and rubbed his face.

He laughed suddenly.

"Did someone new appear?" Luo Yang Siwen's glasses were a bit reflective, and he couldn't see his eyes clearly.

Luo Yang smiled lowly, and said, "The person who died with a note in his stomach? Has there been a new one?"

Du Yusheng didn't answer him, but from the expression on his face, Luo Yang already knew the answer.

"Are you particularly curious? The murderer is already here, why did the same dead as Luo Daheng appear?"

Luo Yang blinked, leaned closer to Du Yusheng's face, and smiled.

He whispered: "Officer Du, do you know the game of death?"

===

Coming out, Du Yusheng leaned against the wall of the corridor and smoked a cigarette.

There is no doubt that Luo Yang is the murderer who killed Luo Daheng, but he doesn't seem to be the end.

As for Chen Xin, Chen Xin's murderer will be found sooner or later, but will that person be Chen Xin's end?

Du Yusheng vomited a smoke ring, he felt that he was in a dead end.

Controlled experiment, controlled experiment, Du Yusheng silently read a few words, two notes, two people died.

Could it be that the answer lies in these four words?

Du Yusheng suddenly remembered the anonymous email he received at the beginning, the photo of the twins.

twin.

Du Yusheng frowned. He felt more and more that the email was not as simple as a harassing email.

Thinking of this, Du Yusheng took out his cell phone and made a call.

"I have an email here, I will send it to the technical team later, help me find the source of this email, and the photos inside."

Du Yusheng leaned against the wall and sighed.

Throwing the burnt cigarettes into the trash can, there was another phone call.

It wasn't about the result of the email, but a call from Xiaobai.

He used the landline in Qin Yan's office. Du Yusheng reckoned that Chen Xin's result probably came out.

"Brother Yu, I have two things on hand now, which one do you go to first?"

Du Yusheng frowned and said, "There's a fart."

Xiaobai smashed his mouth and said, "Brother Qin's result is out. Chen Xin was indeed murdered."

Du Yusheng nodded, and continued, "What about the second thing?"

"Another one died."

Du Yusheng's head buzzed.

"Brother Yu, it's even more strange in the back." Xiaobai continued: "The deceased died in his own home, and his home and Chen Xin's home are in the same community. There are two adjacent buildings, the same floor, and the same room. House, with the same house number."

All the locations are the same except that the building numbers are next to each other.

Du Yusheng clenched his phone tightly and his mind was buzzing.

Then, he saw Li Yao walking slowly down the stairs opposite, and gradually walking towards him.

Looking at Li Yao's face and listening to the strange situation reported by Xiaobai on the phone, for some reason, Du Yusheng had the feeling of wanting to run for the first time.

The author says:

I watched an episode of National Treasure today and burst into tears.I have a cold and a fever recently, QAQ.Also, the game of death is about to begin.
