I don't want to solve the case when I'm a little policeman.

Chapter 884 Experiments prepared for suspects

As soon as Xu Zheng and Zhang Yuqi walked out of the interrogation room, they received a slightly difficult news.

Unexpectedly, the police had just brought back the suspect Wu Jiuming. Immediately afterwards, his mother brought two lawyers to the city bureau and asked the lawyers to intervene in the case.

In addition, leaders from four or five different departments began to find relevant people in the municipal bureau to inquire about the cases being handled by the serious crime brigade.

It turns out that Wu Jiuming's father is the leader of a small department, and the elders of the Wu family have been working in various departments in Changming since the founding of the People's Republic of China, although Wu's father's level is not as good as before.

But there is still more or less incense.

Xu Zheng got this information from Li Wanwan and did not take it to heart. Fang Hanchuan's disappearance was a criminal case. If the person was really killed by Wu Jiuming, then he had better admit the crime.

Among them, whether he committed intentional homicide or manslaughter depends on the results of the police investigation, the determination of the procuratorate, and the final judgment standard of the court and even the court of final appeal.

There is room for maneuver.

Maybe he was sentenced to death for intentional homicide in the first trial. Maybe he got a letter of understanding from the family of the deceased before the final trial, so he might still be sentenced to 15 years in prison.

Therefore, Xu Zheng has always dealt with such related criminal suspects impartially. How the procuratorate and the court will determine the case in the future is a matter for them.

Of course, he was roped in to be a strong man in this case, and he had no involvement in how it was handled.

But before he entered the conference room, the phone rang. The caller was his father's former colleague, who now works in a certain branch.

Xu Zheng didn't answer.

As an investigator, he could do something that was beneficial to the suspect in violation of regulations during the handling of the case, but he did not bother to do such things.

"Haha, I didn't expect that people looking for connections would come to you."

When Zhang Yuqi saw that Xu Zheng was just looking at his phone, he muted it and didn't answer the call. She crossed her arms and looked like she was watching a good show.

"Isn't there Captain Zhang?"

Zhang Yuqi disdained to answer this topic and curled her lips with a cold smile. Xu Zheng smiled bitterly and shook his head, secretly cursing himself for forgetting the rumors about the captain in front of him in the outside world.

But there is a so-called cold-faced executioner.

Asking her to do things is 100% counterproductive.

Putting aside these external factors, a group of people entered the conference room. Wan Haihong and Yan Zizheng finally walked in. Everyone began to study and judge whether the real suspect could be identified as Wu Jiuming based on the existing evidence.

First of all, Wan Haihong set a tone for the case and investigated Fang Hanchuan's disappearance in a realistic and realistic manner. No outside voices could be involved in the case.

Then Li Wanwan presented to everyone the clues he had just investigated in this case.

In addition to Fang Hanchen's transcript, there is also the remote transcript of the party involved, Cheng Man.

And now Cheng Man was also sent to the city bureau by the police from Yongning Police Station. The transcript they had just made for her was repeated in person, and she signed and fingerprinted it.

According to Cheng Man, she didn't take Wu Jiuming's pursuit of her seriously, mainly because they had only met twice, and the man had only spoken a few words to her.

There is no love chat between men and women at all.

This is also the reason why Wu Jiuming was not included in the list of suitors she provided to the police.

To put it simply, she didn't care about Wu Jiuming, her secret admirer.

In addition to the transcripts of the two of them, Huo Weian just arranged for his colleagues to contact the police station in the jurisdiction of Changming Normal University and ask them to send someone to find the classmates Wu Jiuming and Fang Hanchen often played with.

And make remote transcripts for them.

This work is still in progress, but there is probably little hope. After all, if anyone knows that Wu Jiuming is the murderer, there is a high probability that they will immediately confess to the police when they come to their door.

The search for witness evidence has not yet yielded results, let alone physical evidence. However, the good news is that Huo Weian and the others have contacted the telecommunications operations department and obtained Wu Jiuming's mobile phone.

All detailed itineraries on February 2nd.

What excited the investigators was that he did go to Xige Village during his itinerary that day, but unfortunately after he arrived in Xige Village, his mobile phone could no longer perform positioning analysis.

This situation is not a simple shutdown, but the phone card is pulled out and the network is disconnected.

Of course, it is also possible that the phone was dropped and cannot be used, or it was soaked in water and short-circuited.

This is also the reason why Wu Jiuming’s phone number was not found among all the mobile phone signals at the location where Fang Hanchuan disappeared.

If Wu Jiuming is really the murderer, then he cut off the Internet function of his mobile phone, which means that his murder was premeditated. If he is not the murderer, then there is no need for further investigation.

"Just because Wu Jiuming went to Xige Village on the day Fang Hanchuan disappeared doesn't prove that he is the murderer. Do you have any other clues?" Yan Zizhong looked up at Zhang Yuqi and Xu Zheng.

Now that the Wu family and their lawyers are waiting at the criminal police detachment, he feels it is too much to try Wu Jiuming based on this evidence alone.

Although Wu Jiuming posted a video of his crush on Cheng Man on Douyin and also made an AI video, this does not mean that he is related to Fang Hanchuan's disappearance.

Therefore, in terms of interrogation, the task force still lacks a piece of favorable evidence that would make Wu Jiuming not only dare not refute, but also have to admit the mistakes he made.

But that’s where the difficulty lies.

When Xu Zheng saw that no one answered Yan Zizheng's question, he happened to come up with a solution, "Let me ask everyone a question. With the evidence we have now, can we capture Wu Jiuming?"
If he is really the murderer. "

Zhang Yuqi shook her head slightly, "Let's assume that Fang Hanchuan was killed and the murderer was Wu Jiuming, but his method of disposing of the body was very professional. We have already organized police to investigate any corner within a three-kilometer radius of Xige Village.

Only two fingers and half a nail were found.

This proves that Wu Jiuming has very strong counter-reconnaissance skills. After ten days, he must have sorted out what he did.

If there was any missing evidence that could prove that he was the murderer, he would have surrendered to the police station long ago.

So I think surprise interrogations now have little effect. "

The little effect is that the interrogation cannot come out. Xu Zheng said, "I suggest that we don't list Wu Jiuming as a suspect for now. This time we only interrogate him, not interrogate him."

Detain him for 12 hours or let him out after dawn.

When questioning them, the questioning personnel should show a confident side.

I want to make a bet to see whether this person committed intentional homicide or manslaughter. If it was the former, he must have cleared up all the evidence against him.

If it's the latter, maybe when he gets home, he'll clean up the evidence that he hid and doesn't know what to do with.

Maybe it's Fang Hanchuan's relic, or maybe it's the blood splattered on his clothes from his murder.

Or maybe it's something he saved to his computer. "

Wan Haihong frowned, "You mean we suddenly brought Wu Jiuming here and caught him off guard, betting that he had not processed all the evidence, so we let him go."

Normally, he would definitely clean up those things as soon as possible after returning.

But what if he reacts? "

Xu Zheng spread his hands, "If he really reacts to this trick of playing hard to get, then I have another trick, let Fang Hanchuan's remaining two fingers speak." Everyone was puzzled, Wan Haihong was even more impatient, and urged: "You kid It’s too late to show off, just let it go.”

"Let's take a look at the broken section of the finger." Xu Zheng first asked Li Wanwan to find the forensic identification certificate and let everyone review it again, "Forensic identification showed that Fang Hanchuan's finger was cut off while he was still alive.

And he cut off two fingers with one knife.

The cross-section is curved, indicating that the knife wielder cut off Fang Hanchuan's index finger and middle finger with a wave of his hand. "

As Xu Zheng spoke, he held his cell phone in his hand like a fruit knife, and asked Li Wanwan to stretch out the index and middle fingers of her right hand, pretending to point at people and curse.

"Everyone, you see, when many people are cursing someone or when they are particularly emotional, they will always point their index finger or index finger and middle finger at the other person to curse." Xu Zheng looked at Wan Haihong, "When Wan Ju criticized me just now, everyone should see 's very clear.

He also tapped me with his right index finger. "

Wan Haihong was stunned, recalling his own habits, and nodded with a wry smile, "It seems like pointing your index finger and middle finger at people to curse, many people are used to this."

Yan Zizhong also nodded, "I think I criticize people in this way too, haha, I have to pay attention in the future, otherwise I may be like Fang Hanchuan.

When he pointed at someone and scolded him, he cut off two of his fingers with a knife. "

"That's my guess." Xu Zheng nodded and revealed his other plan, "If Wu Jiuming continues to refuse to cooperate, I am going to let him help with an experiment.

Let him hold a knife and perform the experiment of cutting the index and middle fingers of his right hand.

As long as the cross-section of the severed limb is about the same as Fang Hanchuan's finger, he can prove whether he is the murderer.

I estimate that at that time, he was most vulnerable to mental breakdown. "

"Wait a minute." Huo Weian had a creepy feeling when he heard Xu Zheng asked Wu Jiuming to do an experiment on chopping off his fingers, "Xiao Zheng, are the fingers you are talking about real fingers or dummy fingers?

If there is a dummy, how should we conduct the experiment? "

Xu Zheng was speechless, "Of course it's a dummy, find a plastic model with the same height as Fang Hanchuan, and then let his wife Cheng Suyue recall the details of his swearing.

However, the model's severed fingers cannot be replaced with plastic.

Think about it, everyone, what should I use? "

Wan Haihong already understood the real purpose of Xu Zheng asking Wu Jiuming to do this finger-cutting experiment, so the idea that the cross-section of the wound was the same was just to fool people.

The real purpose is to make Wu Jiuming collapse inside.

Ordinary people will have psychological disturbances after killing someone. For example, the police have to write a report and make a psychological diagnosis every time they shoot. But if Wu Jiuming, an ordinary person, is really the murderer.

If you dream back at midnight, there is a high probability that you will have a nightmare.

So the so-called model’s fingers actually don’t matter. Plastic ones are unrealistic, and other materials are similar. Wan Haihong couldn’t wait to give it a try, “I think I’ll just use chicken feet.

Those big cock paws.

After buying it back, Xu Zheng, don’t you know how to do beauty treatments? You happened to process these chicken feet into human fingers. It’s best to make them exactly the same. "

Xu Zheng wanted to refute that he had never done this job before, but when he saw that other people in the conference room had no experience in this area and were not even good at beauty treatments, he had no choice but to accept it.

After the meeting adjourned, Zhang Yuqi and Huo Weian went to inquire about Wu Jiuming.

The fact is as Xu Zheng speculated, Wu Jiuming did not admit that he killed or kidnapped Fang Hanchuan.

He just said that he wanted to go to Huangqing Lake that day, but when he took the bus to Xige Village and got off to buy something, he discovered that his mobile phone had been stolen.

As for when he lost it, he said he didn't know because he fell asleep in the car.

In this regard, after dawn, the task force found from the surveillance video provided by the bus that he was indeed sleeping with his head lowered, but the video did not capture the theft of his mobile phone.

Wu Jiuming also said that he only knew Fang Hanchuan, the brother of his classmate Fang Hanchen, in Xige Village, but he personally despised this man who married into the Cheng family, so he found out that his mobile phone was missing.

He actually walked all the way back to Yongning Town, found a relative of his there, and borrowed money before returning to the city.

On this point, the task force later verified that Wu Jiuming should not have lied. He did not take the Chuning Expressway, but took the rural roads below. There were no surveillance cameras throughout the journey.

Nowadays, we can only find the driving recorders of passing vehicles, but this takes time, and the results cannot be obtained in a day or two.

However, although Wu Jiuming did not lie, the time he provided did not match up. The straight-line distance from Xige Village to the market town of Yongning Town was about 10 kilometers.

The walk takes about two hours.

But it took him twice as long.

Wu Jiuming explained that he usually doesn't like running and would walk for a while and take a break. Anyway, he has reasonable excuses for the police's questions.

Including that he can obviously borrow his mobile phone to call his classmates or family members to borrow money. If that doesn't work, he can also find a supermarket and use facial recognition to exchange cash.

You can also go to the bank and withdraw money with your face.

If all else fails, you can call 110.

Therefore, many of his behaviors are not normal. He did not call the police when his mobile phone was lost. He walked back to Yongning Town to find relatives when he had no money. He looked down on Fang Hanchuan and had a secret crush on Cheng Man.

All kinds of unreasonable things also prove one thing: he is related to Fang Hanchuan's disappearance.

After Zhang Yuqi's inquiry was over, before dawn, at around five o'clock in the morning, she sent Li Wanwan to send Wu Jiuming out of the office building, while Wu's mother had been waiting outside.

And the lawyer hired by the Wu family picked up Wu Jiuming.

Not long after Wu Jiuming left the city bureau, Xu Zheng also made more than thirty fingers. It was quite complicated to say, with chicken feet inside and a layer of biologically cultivated humanoid skin on the outside.

The nails were fake nails purchased from a nail shop before leaving, and were repaired one by one and put on.

Finally, it was installed on the palm of a model of the same height as Fang Hanchuan. It was drilled and bound by iron sheets. It was very secure, but it was a little uncoordinated, but it did not affect the experiment.

Then put the model in Fang Hanchuan's clothes.

Xu Zheng also specially painted the model with Fang Hanchuan's makeup, using biological human skin that he had purchased before. Coupled with his current disguise method, it can be said without looking closely.

Just like Fang Hanchuan himself.

At least that's what Cheng Man, who came to the city bureau to take notes, thought.

Looking at Wu Jiuming who was taken home by his family, he couldn't help it after all. After returning home, he went into his room and turned on his computer immediately, and deleted all the Ai videos about Cheng Man in the computer.

There are also several AI videos of killing Cheng Man.

The moment Wu Jiuming returned home and started his computer, Huo Weian, who was responsible for monitoring him, asked the Internet police to hack into his computer simultaneously and obtained these AI videos.

But these videos cannot prove that Wu Jiuming killed Fang Hanchuan.

So at eight o'clock in the morning, Wu Jiuming, who had not even had breakfast when he got home, was taken to the city bureau by the task force in order to cooperate with the police in conducting experiments.
