Detective: Open your eyes, I am handcuffed in the interrogation room

"I admit it, let me be sentenced!"

In the interrogation room, Wu Yuanshan's face flashed with anger, as if he had broken a jar.

Chen Yi took back his right hand that was hanging in the air. Compared to Wu Yuanshan's loss of control, he became calm at this moment, and there was no expression on his face.

"Wu Yuanshan, the case will not end when you come here. We will continue to investigate." He said, "Even if this person runs abroad, he will not escape death. Don't think too much."

Killing people and mutilating their bodies is extremely bad in nature. Once caught, there is no way to escape the death penalty, and it is very likely that there will be no chance of probation.

"Overseas?" Wu Yuanshan was surprised for a moment, and then his expression changed, "You...what do you mean??"

Chen Yi caught Wu Yuanshan's expression and then said: "Did your son kill Wu Qianqian?"

"What the hell?!" Wu Yuanshan became excited, "What nonsense are you talking about here! What does it have to do with my son! He goes to school in the Imperial City!"

Chen Yi: "Won't you come back in the middle?"

Wu Yuanshan: "You...he rarely comes back except for holidays, he..."

Chen Yi interrupted: "Wu Qianqian disappeared during the holidays."

Wu Yuanshan: "..."

His expression changed a few times, and he gritted his teeth and said, "This matter has nothing to do with my son. I killed him, he really did!"

Chen Yi spoke: "Your confession is inconsistent and there are errors. This cannot be explained by memory loss."

"According to the investigation process, we have to suspect that you are blaming someone else. Who is blaming you for? Your son is the most likely."

"Therefore, we need to bring your son back."

He wanted to see if Wu Yuanshan knew about the extradition regulations between countries.

These words made Wu Yuanshan even more excited: "You can't do this! It really wasn't my son who did it, he doesn't know anything!"

Chen Yi: "Who did that??"

Wu Yuanshan: "Yes... I did it!"

Chen Yi stared at Wu Yuanshan for a while, then turned and left the interrogation room, going to the office to find Zhang Jingang.

"Bureau Zhang, we need the assistance of the Imperial City Police." Chen Yi said while sitting in front of Zhang Jingang.

Zhang Jingang: "What exactly are you checking?"

Chen Yi: "After the 2nd of this month and before leaving the country, the whereabouts of Wu Yuanshan's son will determine whether he has returned to Yangcheng."

Zhang Jingang: "Okay, I will send you a joint investigation letter right away. This case must be investigated clearly, and there must be no unjust, false or wrongful conviction!"

Chen Yi: "I understand, Zhang Ju."

After leaving the office, Chen Yi came to the case handling hall.

"Old He, did Wu Yuanshan's son buy a bus ticket or air ticket back to Yangcheng at the beginning of the month?" he asked.

Shi Xin replied: "I checked, no."

Chen Yi sat down and fell into thinking.

After a while, he took out a cigarette, lit it, and said: "After the bank goes to work tomorrow, we will investigate Wu Yuanshan's bank statements to see if there has been a large amount of money in his bank card recently."

Hearing this, Shi Xin said: "Do you suspect that someone paid him to commit the crime?"

Chen Yi slowly exhaled a puff of smoke and said, "We can't let go of any possibility."

"If Wu Yuanshan is not the murderer in this case, but he knows so many details, and he was even the one who dumped the body, it means that the murderer told him everything."

"But judging from Wu Yuanshan's reaction, he doesn't seem to know that we have no extradition treaty with the Lighthouse Country. If it was his son who did it, would he not tell him about it? The two of them should have had an in-depth discussion."

Ji Xin pondered for a moment and said, "But it is precisely because the mother and son chose the lighthouse country that the suspicion was aggravated. Is it such a coincidence? They chose a country that does not have an extradition treaty."

Chen Yi: "If they choose an unknown small country with obvious intention to escape, we can think so."

"However, the Lighthouse Country is a powerful country in the world, and its educational resources and development level are among the best in the world. Even if they choose the Lighthouse Country, it is understandable and cannot be used as a basis for inference."

He Xin nodded: "That's true. Let's check. If Wu Yuanshan's son has returned to Yangcheng this month and his whereabouts are unknown, then he will be highly suspicious."

A few hours later, it was already very late, Zhuo Yun and the forensic forensic doctor returned and brought important discoveries.

Lu Yongqiang: "Team Chen, blood stains were found at the crime scene, and suspected corpses were found in the abandoned factory. The blood was not cleaned up at all, which is shocking."

"Also, Wu Yuanshan does have a freezer at home. It seems to be in new condition since he just bought it. We found suspicious hair in it and need to conduct a DNA comparison."

Chen Yi: "Where's the taxi?"

Lu Yongqiang: "Hair was also extracted from the back seat of the taxi, and it also needs to be compared."

Chen Yi waved his hand: "Go right away."

Lu Yongqiang: "Okay."

Fang Shuyu didn't say anything, and immediately returned to the forensic room with the forensic assistant to prepare for the identification work.

At this time, Zhuo Yun handed over an evidence bag with a mobile phone inside.

"Captain Chen, found it at Wu Yuanshan's home."

Chen Yi took it and looked at it. He couldn't turn it on anymore. It should be out of power.

The mobile phone case is for women. It is very cute and trendy. If nothing else, it should be Wu Qianqian’s mobile phone.

"Extract the fingerprints on it. The technicians and forensic scientists will work overtime tonight. Let everyone else go to rest." Chen Yi said.

Zhuo Yun: "Yes."

Two hours later, in the early morning, the identification results came out.

The blood stains found at the crime scene belonged to Wu Qianqian.

The blood stains found at the dismemberment site belonged to Wu Qianqian.

The hair in the freezer at Wu Yuanshan's home belongs to Wu Qianqian.

The hair in Wu Yuanshan’s taxi also belongs to Wu Qianqian.

This is already a very complete chain of evidence. Coupled with Wu Yuanshan's confession, the case can be closed here.

but……

On Wu Qianqian's mobile phone, there were only Wu Yuanshan's fingerprints.

At this time, the phone has been charged and turned on, and there is no mobile phone card. It should have been thrown away, but some information in the phone can be determined to be Wu Qianqian's.

At this moment, in the case handling hall, Chen Yi and others gathered to discuss the case, and Fang Shuyu did not leave.

On the whiteboard, Chen Yi wrote out several clues with a marker and matched them with Wu Yuanshan one by one.

Wu Qianqian got in the car.

Crime scene.

freezing.

Dismember the body.

Dump the body.

There are no problems with the clues and confessions. At first glance, it seems to be a solid case, but everyone has seen the previous interrogation process. There are certain doubts about Wu Yuanshan.

"With this mobile phone alone, the case cannot be closed." Chen Yi stared at the fonts on the whiteboard and spoke.

Sitting there, He Xin said: "Yes, this is the biggest... flaw in objectivity."

"This phone was wiped by someone, and it was definitely not Wu Yuanshan. He had no need to do so. His behavior and confession were inconsistent."

Chen Yi nodded and said: "Let's reason about the whole process. First, let's assume that Wu Yuanshan is not the murderer. In this case, two people are involved."

"No matter who the murderer is, don't rely on his son. Just think that the murderer is someone we haven't grasped yet."

"The reasoning process is a bit vague."

"One day this month, the murderer raped and killed Wu Qianqian and put it in a freezer for an unknown purpose. Then about three weeks later, he took out the body, chopped it into pieces, and put it in more than a dozen black bags."

"At this time, Wu Yuanshan appeared. He and the murderer must have met before. I won't mention whether they know each other or not."

"For some reason, Wu Yuanshan reached an agreement with the murderer, exonerated the murderer by taking the blame, and started dumping bodies in the downtown area."

"The reason why we chose to dump his body in the downtown area is to allow the police to find him as soon as possible and close the case."

"Before this, the murderer gave a complete account of the process of committing the crime and dismembering the body, so Wu Yuanshan knew that the mobile phone was also given to him by the murderer."

"However, it was not Wu Yuanshan who contacted Wu Qianqian's parents or sent WeChat messages to her roommates asking for leave. Wu Yuanshan had never operated this mobile phone at all. The role of the mobile phone was only to form a complete chain of evidence."

"The murderer didn't expect that I directly asked about the unlocking method during the interrogation. Wu Yuanshan didn't expect this and had to make it up on the spot."

"Unfortunately, the answers he made up were unreasonable and made us begin to suspect that there was something wrong with his confession."

"Do you need any corrections or additions?"

After finishing speaking, Chen Yi turned to face everyone.

Everyone shook their heads, saying no.

A very reasonable inference that corresponds to Wu Yuanshan's anomalies.

Chen Yi continued: "There are two questions now."

"First, why did the murderer freeze Wu Qianqian's body."

"Second, why did the murderer let Wu Yuanshan dump his body in the downtown area and expose it to the police's sight in the shortest possible time."

Fang Shuyu was more sensitive to the first question and said, "Of course it is to prevent the body from rotting."

Chen Yi looked over and said, "I mean, why didn't the murderer be dealt with immediately?"

Fang Shuyu thought for a while and said, "Maybe... I haven't figured out how to deal with it?"

Chen Yi nodded slightly: "Wu Yuanshan said the same thing. He didn't think about how to deal with it. Maybe this was the murderer's idea."

"Okay, let's just pretend that the murderer didn't think about how to deal with it. Three weeks later, he thought about it, chose to dismember the body, and found Wu Yuanshan."

"So, what about the second question?"

Fang Shuyu said nothing. This was not her strong point.

When did he speak again at this time: "The second question is, of course, so that the police can catch him and close the case as soon as possible."

Chen Yi: "Lao He didn't understand what I meant, why should we do it as soon as possible?"

When is new: "Huh?"

Chen Yidao: "Disposing the body openly will only arouse the suspicion of the police. The reason given by Wu Yuanshan was that he wanted to do something earth-shattering. This reason is still too far-fetched."

"Normal people can imagine that the more secretive this kind of thing is, the better. The more secretive it is, the more difficult it will be for the police to investigate. When Wu Yuanshan is found, doubts about him will be minimized."

"You think, if the police worked hard, spent a lot of police force and time, and finally found Wu Yuanshan, and all the confessions and clues and evidence matched, the first reaction would be to close the case."

"In fact, it is safer not to dismember the body. Let the police investigate slowly. The longer the investigation, the safer the real culprit will be."

"The premise is that the real culprit is a stranger."

The last sentence made everyone's expressions change slightly.

Zhuo Yun immediately said: "Captain Chen, do you mean the murderer is an acquaintance?"

Chen Yi: "Based on the assumption that Wu Yuanshan helped others take the blame, I think the murderer is an acquaintance of Wu Qianqian."

"Going back to the first question, why did the murderer freeze the body and contact Wu Qianqian's parents to ask for leave during the process?"

"The answer is simple: delay time to prevent Wu Qianqian's relatives and friends from discovering that Wu Qianqian is missing and calling the police."

"During this process, the murderer was preparing to take the blame."

"Then, they realized that they could no longer hide it. Wu Qianqian's parents gradually realized that something was wrong and immediately launched a plan."

"Why was the murderer worried that someone would report someone missing, and why was he so eager to expose Wu Yuanshan to the police's sight?"

"Can we think that as long as the police start a comprehensive investigation into Wu Qianqian's interpersonal relationships, the suspect will be identified immediately."

"That's exactly what happened. Wu Yuanshan showed up before we even started investigating."

After listening to Chen Yi's words, everyone took a breath.

Thinking about it carefully, it seems that this is really the case.

If Wu Qianqian was not killed by Wu Yuanshan, there was really no need for him to jump so fast.

Dumping a body in a downtown area and exposing it to surveillance cameras without any disguise is basically telling the police: I am the murderer, come and catch me.

Chen Yi didn't finish speaking and continued: "There are also Wu Qianqian's fingers. Why did Wu Yuanshan throw them away?"

"When I was in the interrogation room, I used the idea that Wu Qianqian had DNA in her fingernails to defraud him. He was very happy and admitted it immediately, but it was completely inconsistent with his previous confession and his behavior."

"It's clear that you want the police to arrest you, so why bother?"

"Perhaps, I unintentionally told the answer. Wu Qianqian's fingers may actually contain the murderer's DNA, and the murderer was injured."

"The murderer didn't dare to bet on the superb identification skills of the police, so he took away Wu Qianqian's fingers and gave only the remaining body to Wu Yuanshan. He told him that if the police asked, he would throw it into the river to feed the fish and bite him to death. This answer."

"All of this tells us one fact: Wu Yuanshan was not the real murderer of Wu Qianqian."

"The murderer is playing a trick on us."

Everyone nodded in agreement, and no one raised any questions.

At this time, Qin Fei sat there and thought for a long time, and suddenly said: "Wu Qianqian's acquaintances? Can you find out by just checking the interpersonal relationship? In Yangcheng, the people she is most familiar with are her classmates and... Jiang Yu."

Chen Yi: "Don't make wild guesses about this matter first. We don't know anything and we have no clues to support the inference."

"The investigation begins after dawn. We need to further confirm whether Wu Yuanshan has a motive for committing the crime. His suspicion has not been completely ruled out."

"I went to visit friends in Wu Yuanshan. Lao He was responsible for investigating Wu Yuanshan's bank records and the surveillance around the hotel."

"Didn't he say that he picked up Wu Qianqian near the hotel? His taxi can always be photographed. Even if you are familiar with the roads in Yangcheng, it is impossible to avoid all surveillance when going to the suburbs."

He Xin nodded: "Don't worry, leave it to me."
