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

Chen Yi and Li Antai came to the scene of the crime. Since they suspected homicide, they had to listen to the evidence and unnecessary speculation would not work.

Cheng Hanjun restored the stool to its original position, then pointed to the rope loop and the stool on the beam and explained. Li Antai looked back and forth, recalled the experiment the other party had just done, and nodded.

It’s okay to have doubts, as long as there are facts to back them up.

Experimentation is one of the commonly used methods in criminal investigation. The situation at the scene is one thing, and whether the suspect or victim can do it is another. If it cannot be done, it is fake.

Li Antai thought thoughtfully: "There are indeed footprints on the stool, but the distance between the stools is wrong, and the deceased did hang himself. In this case... there is a second person?"

Seeing that Chen Yi was not ready to speak, Cheng Hanjun said: "There is definitely a second person. Assisted suicide is unlikely and unnecessary. It should be a homicide."

Li Antai looked at the forensic doctor: "Is it possible that the deceased died in a coma?"

The forensic doctor replied: "He was conscious during the hanging. It is unclear whether he was comatose before hanging. We need to return to the bureau for a comprehensive autopsy."

Antai Lee: "Right away."

Forensic doctor: "Yes!"

The body was removed and the investigation continues.

Gou Qiwen once threatened the developer to hang himself at the gate. Many people present knew about this incident and did not take it seriously. Everyone would say harsh words. Since homicide was suspected, the murderer should have been present at the time. It was possible that he was a villager from the same village. Sex is relatively large.

Disguising homicide as suicide?

Li Antai is thinking about this problem.

To do this, the deceased Gou Qiwen must not have any ability to resist, and it is very difficult to implement.

That was an adult man weighing more than 100 pounds. The rope loop was so high that he could barely reach it while standing on a chair. How did he hang it up?

Cheng Hanjun and others are also thinking, looking for the most reasonable possibility.

There is no surveillance nearby, otherwise the case would be simple.

"Team Chen, what do you think is going on?" Li Antai asked, "If you want to hang Gou Qiwen up, don't you need a lot of strength?"

Chen Yi then spoke: "It's almost impossible to achieve, and the footprints are wrong and the steps are very solid. He hung it up himself."

Li Antai: "Huh? You hung it up yourself?"

Chen Yi: "People like Gou Qiwen can come up with all kinds of weird ideas in order to get more than 500,000 yuan. It is possible to hang up the rope by himself, stuff his head into the rope loop, and scare the developer."

Hearing this, Li Antai's eyes narrowed: "Then the person who takes photos and videos needs to act and pretend to rescue, but this person did not take pictures. After Gou Qiwen stuffed his head into the rope loop, he kicked the stool away ?”

Chen Yi nodded: "Well, the position of the stool is to the left, and the direction it flew out is from the back. Apparently the suspect stood on the right and kicked the stool away with his right foot. Gou Qiwen immediately lost his body support and hung from the beam."

Can you regret hanging yourself? the answer is negative.

Death by hanging only takes a few minutes or even seconds. The rope compresses the blood vessels and the brain will be deprived of oxygen within a few seconds. It is impossible to lift yourself up with your arms unless someone helps.

This is one of the typical suicide methods that cannot save oneself.

Chen Yi's words made Li Antai think it was possible the more he thought about it, and the direction of his investigation was determined: Gou Qiwen's acquaintance was very familiar!

Anyone who can help take photos and videos must have a good relationship with Gou Qiwen.

They have a good relationship, but they still have a grudge against each other, which would be too easy to find out.

"Where's Gou Qiwen's cell phone? Bring it here!" Li Antai shouted. The case might be solved that day.

After receiving the result of his murder, Chen Yi was actually ready to leave. This matter had nothing to do with the developer, but he did not leave and wanted to wait and see.

Li Antai was right to check Gou Qiwen's cell phone. Who did he contact last night? Via WeChat or over the phone?

Even if it is deleted, everything can be found, that is for sure, unless it is a verbal agreement.

These are not important, what is important is the evidence.

There is no surveillance nearby, and no one knows what happened in the early morning. Even if the suspect is identified, the police will have no choice as long as the suspect is killed and denied.

If the facts are consistent with the speculation, then Gou Qiwen completed the process by himself. The suspect's participation was minimal and he just kicked the stool. The other party could have countless excuses.

This case is easy to say and difficult to say.

Li Antai took the mobile phone from his subordinate and opened the call history without unlocking the password.

The latest call record is from 12:30 in the morning, and his name is Gou Junyong.

"Who is Gou Junyong!!" Li Antai looked at the villagers in the distance and shouted loudly.

"I!"

"Comrade police, it's me!"

The young man in his thirties squeezed out from the crowd and trotted up to Li Antai under everyone's gaze.

Li Antai looked at the man in front of him and asked, "Gou Qiwen called you at 12:30 in the morning. What did he do?"

Gou Junyong was very cautious and stammered: "No... I didn't do much. I just chatted. I scolded the developer and said I must get 600,000. There are not many opportunities for this kind of blackmail."

Li Antai stared at Gou Junyong: "Are you two relatives?"

Gou Junyong: "That's right. We have the same ancestor, but they have been on the fifth server. They are very distantly related."

The relationship between the five servers is indeed very far, and men and women can get married.

Li Antai: "Only called? Never came?"

Gou Junyong: "No."

Li Antai: "Think carefully before answering. There are many footprints in this area."

Gou Junyong paused for a moment and said: "I really didn't come, but I was here yesterday. It's normal to have footprints. Comrade policeman... didn't he commit suicide?"

With Chen Yi watching from the side, Li Antai was very alert. People with no background could easily reveal their secrets in front of experienced criminal police.

There's something wrong with this guy.

"Gou Junyong, you are the last person to contact Gou Qiwen. We need you to follow us back to the branch to assist in the investigation." Li Antai was about to take him back.

He was suspected of committing suicide. His last contact person was from the same village. He looked wrong. It would be wrong to detain him first.

Gou Junyong: "Huh? Uh, okay... okay."

He wasn't too resistant.

Chen Yi has been observing Gou Junyong, and is now basically certain that he is the major suspect in this case. The subsequent investigation will depend on the Chengnan Branch. The case should be solved, but the length of time is a matter of time.

"Captain Li, we won't bother you. We have to go to Jiangcheng." Chen Yi said, "If you encounter any difficulties, you can call me at any time. If you are not available, I will get back to you."

It's okay to come and take a look, but it's not good to intervene forcefully. Even if his position is higher than that of Li Antai, it's not necessary. This case is not complicated.

He had the motive to kill but did not dare to take action. When the opportunity presented itself, he kicked Gou Qiwen into a painful death and kicked himself into the abyss. This should be what happened.

"Okay, Captain Chen, walk slowly."

Li Antai did not hold back and said goodbye to Chen Yi politely.

Before leaving, Chen Yi met with the general manager of the subsidiary and told him not to worry, it might be a murder case. If the criminal investigation team of the branch did not need to investigate, he could go back and wait for news, and everything would be done in accordance with the investigation procedures.

There is no need to hide the murder, and word of the ensuing investigation will soon spread.

The general manager nodded repeatedly, feeling relieved.

The project manager felt that he had been "saved", but when he came back to his senses, he found that his back was wet with sweat, either from heat or from fear.

"Fan Lei, let's go." After finally chatting with Jiang Fanlei, Chen Yicheng waved to him and got in the car.

Seeing that the matter seemed to have been resolved, Jiang Fanlei did not want to stay any longer and prepared to leave.

Of course, the purpose of his call to Chen Yi was not to simply share anecdotes. The developer was the Chen Group. The occurrence of demolition households hanging themselves would have a considerable negative impact on the company, so Chen Yi needed to be informed.

Inside a business car.

Chen Yi expressed his affirmation to Cheng Hanjun and the other three: "The observation skills are good. They can raise doubts from the footprints and determine the irrationality of the deceased's suicide process through experiments, so as to draw the conclusion of homicide. It is very good."

Zhuge Cong and Qin Fei looked at Cheng Hanjun, and it was the other party who raised the doubt.

Cheng Hanjun was a little embarrassed and said with a smile: "I have a background in trace detection and am very sensitive to footprints. It is really impossible for such a big wooden stool to fly that far."

Chen Yi nodded: "It is indeed a homicide, it should be Gou Junyong."

Zhuge Cong said: "Did he lie just now?"

Chen Yi: "He lied. He went to Gou Qiwen's home after receiving the call in the early morning. Gou Qiwen was afraid that he really wanted to use acting to force the developer to pay. Once the developer learned that Gou Qiwen was going to commit suicide, there was still a high possibility that he would let go. of."

Zhuge Cong: "Originally, I wanted to find an actor, but ended up finding one who wanted to kill him? Since Gou Qiwen can think of Gou Junyong, there shouldn't be any enmity between the two, right?"

Chen Yi: "People's hearts are unpredictable. There are too many people who feel good about themselves. You think everyone likes you, but in fact no one likes you. You think you can deceive others, but in fact no one believes you. You think others treat you as a fool. My friend, people actually want to kill you."

"In this world, it is very important to know yourself clearly and not to be too confident."

Everyone agreed. What Chen Yi said was very realistic. This is the human heart.

Cheng Hanjun thought for a long time and said: "Without surveillance, Gou Junyong seems unable to plead guilty just based on doubts. What will Captain Li do? Increase the intensity of the interrogation?"

Chen Yi shook his head: "I don't know this person, I don't know."

Qin Fei, who was driving, was curious and his voice sounded: "Team Chen, if it were you, is there any direction for the investigation of this case?"

Chen Yi thought for a while and replied: "In terms of motivation, we first need to figure out Gou Junyong's motive for committing the crime. In terms of process, we may need to use Lockard's principle of material exchange. If we are lucky, we can identify the only suspect. Bad luck. ……Hard to say."

Lockard's material exchange comes from the "Criminal Investigation Course". This principle believes that during the crime process, there will be contact and exchange relationships between criminals and various material entities, that is, material exchange.

The theory includes three aspects. In this case, it is physical exchange.

If the suspect kicks away the stool, then there will be a material exchange between the shoe and the stool. If the two can achieve the only causal relationship, it can be used as conclusive evidence.

The reason why Chen Yi said it depends on luck is because a certain substance may be found on other people's shoes. This situation will lead to many possibilities, which can only be used as clues but not evidence.

"Team Chen, if it's convenient, can you call me and ask in the next two days? I'm very curious about the result." Zhuge Cong made the request, and others also looked over, obviously thinking the same thing as Zhuge Cong.

Chen Yi: "Okay, I'll take the time to ask after we get to Jiangcheng."

…

Ximei Village.

After Chen Yi left, Li Antai immediately started investigation work, listed Gou Junyong as a suspect and took him back to the branch, and personally took charge of the visit and inquiry work.

The first person to visit was the village chief.

"He...he killed?!"

The village chief was extremely shocked. If it hadn't been for the police who said this, he would have scolded him back.

Not committing suicide? How come he killed him? ?

"Who does Gou Qiwen usually have conflicts with in the village?" Li Antai got to the point.

The village chief was at a loss: "No... I haven't heard of it. Everyone really doesn't like Awen, but... it's impossible to kill someone, absolutely impossible. How much hatred would it take to kill someone."

Li Antai: "Where is Gou Junyong? What is his relationship with Gou Qiwen?"

Village Chief: "Ayong and Awen have a very good relationship. They are from the same family. Although they have been on the fifth server, they are still relatives. They often hang out together."

Li Antai: "What are you doing together?"

Village chief: "Let's have fun, play cards and have a drink."

"Playing cards?" Li Antai's eyes flashed, "Do you have any money?"

The village chief was at a loss for words: "Uh... how much can I have? Just for fun."

He didn't dare to lie to the criminal police. The people playing cards and mahjong in the village had some luck, otherwise what would be the point.

Li Antai: "What exactly do these two people do?"

Village Chief: "Ayong has a picking garden and a chicken farm, and Awen...hey, he hasn't done any serious work in the past few years."

Antai Lee: "Are they all single?"

Village Chief: "No, Awen seems to have a new girlfriend."

Li Antai: "From this village?"

Village chief: "Yes, from this village."

Li Antai: "Call over the people who often play cards with Gou Qiwen and Gou Junyong, as well as Gou Qiwen's girlfriend."

Village chief: "Okay."

Most of the villagers were present at the scene, so the visit was easy. Within an hour, everything that needed to be asked had been clarified. The focus was on the dispute between Gou Junyong and Gou Qiwen.

Suspected of gambling? There are indeed facts, but the circumstances are relatively minor. A matter of a few hundred yuan may or may not be punished. Since the murder case comes first, Li Antai only gave him a verbal education.

According to villagers, although Gou Qiwen usually does not do serious work, he is still very skilled in playing cards. Everyone owes him some money, including Gou Junyong.

The amount is very small, only three digits.

Gou Junyong, who has a three-digit debt and owns a picking garden and a chicken farm, has no need to kill anyone. Even if the conditions are perfect, he will not do it. It is a human life, which lacks rationality.

If it's not for money, it might be for love.

Li Antai met Gou Qiwen's girlfriend and asked if there was an unusual relationship between the three, and gained a lot.

Last year, a girl who worked out of town came back to the village for a blind date. She was spotted by Gou Junyong and started to pursue her wildly. He had good conditions and the woman was also interested. Just when the two were about to get married, the woman suddenly became Gou Qiwen's girlfriend.

"Gou Qiwen snatched you away from Gou Junyong, is that what you mean?" Li Antai looked at the girl in front of him.

The girl denied: "It's not a robbery, and I'm not a commodity. Gou Junyong and I didn't succeed in the first place. After meeting his friend Gou Qiwen, I became more fond of him."

Li Antai understood.

Gou Junyong went on a blind date with the girl. The former liked her very much but the latter didn't like her that much. Maybe it was because the girl was in good condition and didn't reject her right away. She wanted to get in touch and see how she felt.

Later, Gou Junyong took the girl to meet Gou Qiwen, and the girl immediately fell in love with Gou Qiwen.

It's a normal thing. Falling in love is a two-way choice, but this is a contradiction.

The motivation is there.

Mental imbalance can also be considered as one of the motives. I own a picking garden chicken farm in the village, and I can be considered a "successful person" anyway. Now there is a company that pays a lot of compensation for demolition. If you don't choose me, choose the second-rate Gou Qiwen?

How am I worse than him? ?

Stealing a woman is different from owing money. If Gou Junyong was given an excellent opportunity, he would definitely kick the stool away on impulse, leading to Gou Qiwen's death.
