Controlled experiment

How did Chen Xin die?

Du Yusheng looked into Li Yao's eyes, and several images suddenly flashed in his mind.

He pulled out the chair and sat down opposite Li Yao.

Du Yusheng played with the disposable wooden chopsticks on Li Yao's table with one hand, raised his eyelids and looked at the expression on Li Yao's face, and said, "I suddenly remembered something." Du Yusheng aligned the two chopsticks and continued. : "Do you still remember Luo Daheng's case, you appeared in the surveillance at the entrance of the crime scene, but now in this case, the time and place have changed, you still appear in the surveillance."

"What do you want to say?" Li Yao stared at the bowl of beef noodles in front of him.

Du Yusheng shook his head and remained silent for a few seconds, wondering if he should tell Li Yao about it.

Taking a deep breath, Du Yusheng stretched out two fingers and said, "About two months ago, I received an email with a picture of two children, twins, who looked exactly the same. It's weird, isn't it, and what's even weirder is that these two kids look exactly like me when I was a kid."

Du Yusheng noticed that the corners of Li Yao's lips moved slightly, he looked at Li Yao and continued: "The problem is, I'm not twins, I have an only-child certificate, this anonymous email combined with the surveillance video I just remembered, Suddenly I was inspired."

Sitting down on Li Yao's desk, Du Yusheng tilted his body and finished the last sentence, "Have you ever thought that you have two people?"

Li Yao suddenly squeezed the corner of his book under the table.

He didn't expect Du Yusheng to have such an idea. Li Yao wanted to let Du Yusheng know the fact of Jing Mo's existence, but definitely not now.

Fortunately, this scene has appeared in Li Yao's mind countless times, and he can handle it with ease.

Li Yao smiled politely, shook his head and said, "You checked mine, you should know more about my family than I do."

"That's true." Du Yusheng yawned and scratched his head, and looked back at Li Yao. The latter's expression was still serious. Du Yusheng walked over and patted Li Yao's shoulder carelessly, and said with a smile, "I don't know why I just Suddenly I had such a bad idea, but then again, you said why my wife sent me an email, I don’t know now, I have received a lot of spam emails, and this is the first time I have a photo of myself.”

After speaking, Du Yusheng laughed a few times, picked up the water on the table and drank it all.

Whether Du Yusheng is stupid or not, whether he is smart or not, Li Yao looked at his back and thought, what if Du Yusheng is just pretending?

Zhuang Hao's fax came two hours later. At that time, Li Yao had already returned home. After taking a shower, he was sitting on the sofa and looking at the medical records of the patients who will be on stage tomorrow.From the six months before Chen Xin was hospitalized until his death, Li Yao checked everything related, but found nothing.It has to be said that Jing Mo found a master this time.In other words, Jing Mo himself is a master.

Looking at the list sent by Zhuang Hao, Li Yao sighed deeply.

There are more than a dozen names on the list, and now five of them are gone. Li Yao took a black marker and crossed out their names one by one.There are a few left, Li Yao looks at their names, really does not know who is next.

It seems that what Jing Mo said that night was correct, Chen Xin did not come to register to see a doctor, he came to find himself for business.

Unfortunately, he died before he could explain his intentions.

Li Yao's identity has always been a secret, how did Chen Xin know, once he died, it would be difficult to know.

The house was a bit hot, so Li Yao took out the remote control of the air conditioner and turned on the air conditioner.

Throwing the list in his hand into the shredder, Li Yao suddenly wanted to smoke a cigarette.Zhuang Hao is now in a place where no birds shit. There are only two hours out of 24 hours a day when there is a signal to communicate with the outside world. It is closed and safe. Li Yao is looking for a good place.Li Yao took a deep breath, feeling that he had also stepped into a road of no return.

Ten minutes later, there was another one on the fax machine.

It was still from Zhuang Hao.

It is a page with two codes and a sentence attached.

'The above identities can be used, one for you and the other for Du Yusheng'

Li Yao looked at this page and smiled. One fax could solve the problem, but he insisted on sending two. It seems that Zhuang Hao doesn't have much communication with the outside world now. One fax is a luxury, and it takes two faxes. Come experience happiness again.

It's all self-inflicted.

===

After returning from Li Yao's office, Du Yusheng went straight back to the bureau.

He was thinking about Qin Yan's autopsy results.

But now it was less than 24 hours before the crime happened, and some superficial scars on the body would not appear until 24 hours later. Du Yusheng also knew that he was a little impatient.

Xiaobai was yawning in the big office. There were two cups of strong coffee on the table, one for himself and one for Du Yusheng.

Seeing Du Yusheng come back with style, Xiaobai immediately stood up and handed him a cup of lukewarm coffee.

Du Yusheng took a sip and asked, "Has the reporter been tried?"

Xiaobai nodded and yawned, "It's the same as what we saw this morning. The round nurse found that she called a few times and didn't answer. And the nurse said that she went to see it around eleven o'clock last night. Chen Xin got up to go to the bathroom, and based on Brother Qin's statement, the time of the crime was probably between eleven o'clock and twelve o'clock, an hour."

"Where are the monitors I mentioned?"

"I also read it." Xiaobai flipped through the computer, and continued: "Except for the section in front of Chen Xin's ward door, the valuable ones are gone."

Saying is the same as not saying.

Du Yusheng rolled his eyes.

"Where's Chen Xin's family?"

Xiaobai sighed, tilted his mouth, and pointed to the lounge next door.

A total of three family members came, Chen Xin's wife, father, and his daughter.

The wife seems to be still very emotional, her face is still red, she is still chattering, and she is probably still cursing the hospital.The one who is dull is the old man, Chen Xin's father, the old man is not young, sitting there, staring at the floor motionless, his eyes are completely devoid of energy, the well-dressed old man seems to have lost his soul .The one on the far side was his daughter, who looked like she was in junior high school, and she was also sitting there, holding her mother with one hand, with tears on her face, which made people feel sad.

Du Yu adjusted his appearance, opened the door of the lounge with Xiaobai and walked in.

"Hi, my name is Du Yusheng, and I'm in charge of Chen Xin's case."

As soon as the words fell, Mrs. Chen stood up suddenly. Her daughter seemed to want to stop her, but Mrs. Chen shook her off vigorously.

"Let me tell you, it's the hospital's problem." Mrs. Chen said sharply: "Our old Chen is in very good health, why did he die in the hospital? He was fine at home. It's not the hospital's problem. We're not done! I'm going to sue, sue!"

Mrs. Chen's face was flushed, and spit spattered out.

Du Yusheng glanced at Xiaobai.The latter waved his hand to him and put it in his ear.

Xiaobai said softly: "Mrs. Chen is a housewife. For many years, the family has relied on Chen Xin's business. Chen Xin's business has lost a lot in the past few years, and the money left is not much. If she dies in the hospital, she can file a lawsuit Claims."

Du Yusheng understood.

It seems that the relationship between the couple is not deep, and they are calculating each other.

This Mrs. Chen was completely responsible for the hospital, and she couldn't ask anything.

Du Yusheng winked and asked Xiaobai to invite Mrs. Chen and her daughter to another lounge.

The noisy room fell silent in an instant, and the old man in front of him still maintained his previous posture without moving, as if everything that happened here had nothing to do with him, and he lost consciousness. Du Yusheng called twice before the old man came back. Suddenly, he looked at Du Yusheng blankly.

The old man still doesn't seem to believe the fact that his son is dead, and his eyes are always staring blankly at one place, as if he has lost communication with the outside world and has aged a lot.

"Hello, sir."

Looking at the old man's face, Du Yusheng felt that his throat was a little rough, and he didn't know how to speak.

Chen Xin is more than ten years older than himself, but Du Yusheng feels that no matter how old the child is, the heart of being a parent will always be the same.

For some reason, Du Yusheng suddenly remembered himself.

"Master." Du Yusheng took a cup of hot water for the old man, handed it over to the old man, and said, "Don't be too sad, pay attention to your body."

The old man took the cup of hot water tremblingly, and the tears he had been holding back flowed down in an instant.

"I... Comrade policeman, why did my son die?" The old man tremblingly held Du Yusheng's hand, choked up and said, "I heard she said it was a medical accident, is that true, comrade policeman? What's wrong with Chen Xin? I really want to be sick for him. I have lived for decades, and I have lived enough. Is it okay if I die for my son? I will suffer for him, as long as my son can come back. Or I can continue my life to him. Ah, the white-haired man sends the black-haired man, how can he make me live."

Because the old man was too sad, he spoke intermittently, and the tears could not stop swirling in the circles of his eyes.

Du Yusheng took a deep breath and bit his lower lip.

"I heard from Mrs. Chen that your son's business has not been doing well recently."

The old man wiped the tears from the corners of his eyes, and slowly came back to his senses.

Nodding slowly, "I lost a lot. I don't know much about business matters. I just watched him complain to us during the meal. Over the past few years, he has been losing money every year. Finally, Chen Xin went to ask for it." Chen Xin was in a hurry because he didn’t want to come back after several times and didn’t get the money back.” The old man said this, thought for a while, and said, “Is Chen Xin’s illness related to this matter? Has he been Thinking about getting the money back and getting sick?"

It seems that this well-known car dealer around the island is not doing well.

Du Yusheng then asked: "Do you still remember whose money he owned?"

The old man shook his head, "I knew his surname was Gu, and he was a classmate of Chen Xin."

Being forced to send money, I feel resentment and murder.

A reasonable idea came to Du Yusheng's mind.

"Then do you know who Chen Xin has been talking to on the phone, meeting, or having an affair with?"

The old man lowered his head and shook his head slowly. "I don't know what you said. I don't participate in his work. You can ask my daughter-in-law."

The old man looked at the daughter-in-law who was still arguing in the other lounge and sighed.

"Without Chen Xin, she will have a difficult life with her children alone. Besides, Chen Xin has paid too much over the years, and there is too little left for her. Don't mind her like this. In fact, she also Not good."

Du Yusheng wondered why a rich businessman kept losing money again and again.

"One more question." Du Yusheng said, "How is Chen Xin's sleep recently?"

The old man thought for a while, "It was fine before, but recently he couldn't sleep well at all because of money transfers. I always saw him smoking in the living room when I got up at night, and he was a light sleeper, and he could wake up with a cough."

Du Yusheng nodded.

It seems that the vent is drugged.

Before leaving, the old man stood at the door and asked Du Yusheng something. He wanted to see his son again.

Du Yusheng took the old man to the mortuary and opened the drawer. The moment he saw his son's face, the old man couldn't restrain the pain in his heart anymore, and covered his face and wept.Du Yusheng had seen the world, but he couldn't take it anymore. He went out and closed the door of the morgue with his backhand, and put a cigarette in his mouth at the door.

Du Yusheng didn't drive today, and he didn't want to take a taxi back, so he asked his colleague to borrow a scooter.

I haven't ridden this kind of transportation for several years. Du Yusheng stepped on the small motorcycle and put on the helmet, and the wind whizzed by his ears. Du Yusheng felt very refreshed, as if he could blow away the feeling of aggrieved heart, Images of the old man looking at his son kept appearing, watching the old man chattering about his child, Du Yusheng lifted the glass cover in front of the helmet, and forced the wind to blow his tears back.

He missed old man Du, and he also wanted to hear old man Du scold him, and he also wanted to hear him talk about himself.

But this is impossible.

Du Yusheng parked his scooter downstairs, walked upstairs slowly, and opened his door.

His living room has a large usable area, larger than it looks, because there is a secret door behind the living room.

Du Yusheng opened it, revealing a black and white photo of Mr. Du.

This photo was taken when we went out to sea together several years ago, and the old man smiled very happily.

Du Yusheng forcibly held back his tears, and burned three sticks of incense to Mr. Du.

He bowed three times respectfully.When Mr. Du disappeared, only one car was left behind. That car was later transformed into a classic car by Du Yusheng, and he is still reluctant to throw it away.Tracking the car, Du Yusheng also discovered the isolated island by chance, and then found a watch exactly like himself on the isolated island.

Du Yusheng pulled away the chair next to him and sat down with the old man.

"Dad." Du Yusheng pursed his lips and smiled, "I miss you a little bit today."

The old man smiled on the photo, and Du Yusheng went over to wipe the dust off the photo.

"Actually, I'm quite incompetent. I can't bring your body back. I can't find out the cause of the accident, and I can't find the murderer." Du Yusheng picked up the color print behind the photo, which says Control Experiment Four Du Yusheng looked at those four words and smiled, "But don't worry, I think I am getting closer to him. Sooner or later, I will kill him with my own hands." Du Yusheng smiled to himself, and pulled away The curtain behind the photo.

"Give the old man some sunshine."

With the warm sun shining on his body, Du Yusheng felt that he had returned to the world.

The cell phone in his pocket is going to ring.

Qin Yan called.

Du Yusheng closed the secret door and went out to answer the phone.

"How is it, is there a result?"

Qin Yan sighed and said: "The cause of death will have to wait. But I found something in Chen Xin's stomach. It said 'Controlled Experiment'. The size of the package is exactly the same as the one in Luo Daheng's stomach .”

Du Yusheng's mind was buzzing.

Controlled experiment I have seen this note in two places before, in Daheng Luo's stomach, and in the car where Mr. Du disappeared, and now there is one more thing, in Chen Xin's stomach.
