  After staying at home for two days on the weekend, when he went to work on Monday, Zhao Donglai took the time to apply for Zheng Changjun.

Hearing that they wanted to investigate previous unsolved cases, Zheng Changjun was very supportive.

"The files of the five cases I picked for you before happen to be still with me. You can take them back and study them with Luo Fei first. If they are not suitable, tell me."

"Ok."

When Zhao Donglai returned to the police force with the file, he immediately notified everyone of the meeting in the conference room.

"Why are there suddenly another meeting? Is there any arrangement from above?"

"Any arrangement is fine, as long as there is no more training."

"Speaking of training, I don't know if I passed this time."

"Then I will definitely fail..."

In the conference room, everyone was discussing.

It wasn't until Zhao Donglai came in that everyone stopped speaking.

"Please cheer up for me. Didn't you guys want to make meritorious deeds and earn honor before? Now the opportunity has come!"

Zhao Dong said and raised some files in his hand.

Liao Xingyu seemed to have thought of something, "Captain Zhao, is this a file on an old unsolved case? Have you really gone to apply to Director Zheng?"

"Of course, is it possible that I can still joke?"

"These five files were all selected by Director Zheng himself. He asked us to study them first. If we feel that the case is not suitable, we can also look at other cases."

"In short, Director Zheng trusts us so much. We can't let him down. Please be careful. It depends on this time whether we can get your lost dignity back!"

Under Zhao Donglai's encouragement, everyone instantly became more motivated.

"Don't worry, Captain Zhao, we promise not to hold you back!"

"Yes, we will fight for the honor of our detachment!"

"Okay, let's study the case now."

Zhao Donglai had already studied these five files carefully before coming here.

The difficulty of solving the case is not great, but it is not simple either. The main reason is that some key evidence is missing, and the suspect cannot be identified, which makes the case unsolved.

Everyone got together and read the five files one by one, and finally got a general understanding of the case.

Zhao Donglai said, "I have finished reading the files. Now let's share our opinions. Which of these five cases do you think is the easiest to conquer?"

"I think this wife's disappearance case is good. I heard that Team Leader Luo solved Yang Dawei's wife murder case before."

"The two cases are similar in nature. Based on his experience, it shouldn't be difficult to solve the case."

"How about the child's heart being gouged out? Such a brutal way of committing a crime is obviously a revenge crime. I always feel that the murderer must be a fellow villager who has a grudge against the child's family."

"It's a pity that there were too few clues at the time. This time, with Team Leader Luo taking over, I think there will be no problem."

"It's still this..."

Everyone was chatting with each other.

Zhao Donglai waited until they had finished talking, then looked at Luo Fei who was standing aside, "Luo Fei, what do you think?"

Hearing this, everyone also stopped their discussion and turned to look at Luo Fei.

It has to be said that although Luo Fei has only been in the police force for more than two months, he has completely become the backbone of the entire police force.

Despite the lively discussion they just had, their confidence is actually based on Luo Fei.

Under the expectant gazes of everyone, Luo Fei thought for a moment and then said, "I think we should first investigate the case of the child's heart being gouged out by Zhao Hai."

The case Luo Fei was talking about was from May three years ago.

The victim, Zhou Kairui, was a little boy who was only three years and two months old and lived in Group [-], Baimao Village, Qingshan Town, Guangyuan County. When the incident occurred, his grandfather went to town for business, and he and his grandmother were home alone.

Around [-] o'clock in the morning, grandma went back to the house to cook, leaving Zhou Kairui playing in her yard.

About ten minutes later, when his grandmother went out, she found that the child was missing. She immediately launched a search for the whole village, and then some villagers called the police.

Half an hour later, the police arrived.

After briefly understanding the situation, the police immediately divided into two groups. One group continued to search the village with the villagers, while the other group immediately called for surveillance on several main roads leading outside the village and issued a notice to assist in the investigation.

An hour and a half later, comrades from the county also rushed to the scene of the crime with three police dogs.

After the police dogs sniffed the children's daily clothes, the three police dogs lost their way after tracking them under a big tree at the entrance of the village.

After that, everyone searched unremittingly for two days, but there was still no whereabouts of the child, and the comrades who were investigating and monitoring did not find any suspicious vehicles.

One morning three days later, a villager who went up the mountain to collect hogweed found Zhou Kairui's body in the grass at the back of the mountain.

After receiving the situation, the local police station and the county's criminal police team arrived immediately and conducted a cordon-off investigation of the scene.

According to the case record at the scene, Zhou Kairui was lying on his side in the grass, wearing a white long-sleeved shirt and brown trousers, the same clothes he was wearing when he disappeared.

Except for obvious pinch marks on the child's neck, there were no obvious wounds on the exposed skin.

According to the preliminary identification of the forensic doctor, the child's face was purple and blue, his eyes were bulging, his conjunctiva was congested, and his tongue was sticking out, which was consistent with mechanical asphyxiation.

However, when moving the child's body, the forensic doctor found a large amount of blood on the clothes on the child's chest.

After lifting up the child's clothes, it was discovered that a large hole had been artificially separated from the child's heart. The bones and flesh were everted, the sternum was broken, and the child's heart was missing.

In the meantime, the police sent additional manpower to search the area around the crime and deployed six police dogs from the county, but they could not find the child's heart.

Subsequently, the case was taken over by the Guangyuan County Criminal Police Team, but there was no progress in the investigation for three months, so the county Criminal Police Team had to go to the city for help.

Subsequently, the case was taken over by their police team, led by Lu Jianfei at the time. After receiving the request for help, he immediately took everyone to Guangyuan County to understand the situation.

After that, I visited Zhou Kairui’s family, neighbors and people in the same village. They initially believed that this was a case of revenge killing, so they focused on the villagers who had issues with the Zhou family.

After understanding, they also successfully found several villagers who had conflicts with the Zhou family, but these were trivial matters and not serious enough to require murder for revenge.

Moreover, through interviews and investigations of these families, it was found that either there was no opportunity to commit the crime, or there was an alibi.

After several months of investigation, they still couldn't find any clues related to the case, and the case became an unsolved case.

Later, Luo Fei explained the reason why he chose this case.

"First of all, this case occurred three years ago. The time span is not that big, so it is relatively easy to investigate."

"Furthermore, Zhao Hai's analysis does make some sense. The victim was only three years old. It is impossible for a child of this age to run too far away from home alone without the company of an adult."

"So it can only be proved that the victim was probably taken away from his home by the murderer. However, according to the records of the villagers visited, no one saw any outsiders entering the village that day, and there were no outside vehicles."

"I guess the probability of this case being committed by someone from the same village is very high, so we only need to conduct a detailed and comprehensive interview with the people who were in the village at the time. I believe we will definitely find something."

Zhao Donglai naturally believed in his judgment, "Okay, let's investigate this case first."

"In this way, the first and second groups are responsible for the visit, and the third and fourth groups are responsible for analyzing and integrating the evidence and testimony related to the case. The police dog squadron and the technical squadron will assist."

After some arrangements were made, everyone came down and went their separate ways.

Because they were still some distance away from Qingshan Town, in order to save time, Luo Fei and Liao Xingyu decided to set off immediately after discussing it.

This way they still have time to visit two more households in the afternoon.

In the car.

Luo Fei and Liao Xingyu are still discussing the case.

"This case has been going on for so long. The murderer probably thought that the police had given up long ago. If we go to visit him again at this time, there is no guarantee that he will not panic."

"So, Team Leader Liao, please remember to say hello to everyone, and pay more attention to the other person's demeanor when visiting."

"Another thing is to try to be more careful when visiting, and don't just focus on the feud with the Zhou family. For example, which family had something big happened during that time, or who behaved abnormally, you need to find out more about these. "

"Okay, I'll say hello to them in a moment."

Liao Xingyu nodded in agreement, paused and then asked doubtfully, "Luo Fei, do you mean to say that you suspect that this case is not revenge of an enemy?"

"I can't say this for the time being. Judging from the murderer's modus operandi, it does look like venting anger and revenge. However, according to the investigation records in the file, the police investigated the Zhou family's enemies and found no suspects."

"This proves that either we have some clues that we haven't found, or it is indeed not an enemy who committed the crime, so in this case we have to be prepared."

As he said that, Luo Fei suddenly said, "Team Leader Liao, let's make a bold assumption now. If this case is not the revenge of an enemy, who else do you think is most likely to commit the crime?"

"Except for vendetta..." Liao Xingyu frowned and thought seriously for a while before shaking his head.

"If there wasn't any deep hatred, I can't think of anyone else who could do such a cruel and bloody thing to a child. A normal adult wouldn't be able to do such a perverted thing."

"Yes, normal people cannot do such perverted things, so can we boldly speculate that the murderer is not a normal person?"

"You mean... the murderer has a mental illness? That is also possible, but the murderer in this case obviously took away the children and then killed them in a planned way. This is not in line with the characteristics of a mental patient."

Generally, mental patients commit crimes on the spot after a sudden onset of illness. Such planned crimes are rare.

"Have you misunderstood me? I'm not saying that the murderer is mentally ill, but that maybe for some reason, he was mentally abnormal, and thus had a reason to kill Zhou Kairui?"

"You also know that the victim lives in a rural area, and most of the people in the village are left behind by the elderly, and these people have a common characteristic, which is superstition, ignorance and stubbornness."

"For example, there was a similar case..."

Luo Fei's guess was not just nonsense, but was based on facts.

He happened to see a similar case when he was reading a book a few days ago. The victim and the perpetrator were villagers in the same village and were neighbors.

The victim's family was well off, but the perpetrator's family was in dire straits, and he was still alone in his fifties.

The unsatisfactory life led the perpetrator to become superstitious about the idea that Feng Shui can change his life, and he spent all his money on it.

However, he spent a lot of money, but his life did not improve. The perpetrator became more and more obsessed, until one time he found a master. After the master's guidance, he was unable to get rich because his neighbor was trying to control him. .

Anyone with a little bit of common sense can know that this statement is nonsense, but the perpetrator believed it. After returning home that night, he took a kitchen knife to his neighbor's house at night and killed someone who was the same age as him. The neighbor was killed directly.

Luo Fei briefly talked about the case and then analyzed, "In this case, not only did the perpetrator and the deceased have no enmity before the incident, but on the contrary, the two families had a very good relationship, and the deceased's family also took great care of the perpetrator. .”

"It can be said that he had no reason to kill at all. However, in the end, because of the master's words, he was able to kill without hesitation. When faced with the accusations from the police, he could plausibly say that he only killed to change his life."

"So based on this case, can we boldly assume that an old man in the village had a superstitious belief in Feng Shui and believed that the victim was incompatible with him, so he killed the person."

"Team Leader Miaoah Luo, your speculation is indeed very reasonable!" Liao Xingyu nodded repeatedly, looking surprised.

Zhang Wei and the others were enlightened.

At this time, He Xin, who was next to Luo Fei, said thoughtfully, "Team leader, according to your analysis, can the child's missing heart be explained as being used by the murderer for other purposes, such as cooking? "

All the police officers who previously investigated this case agreed that the murderer took the child's heart out of revenge and caused pain to the child's family.

But this reason is somewhat far-fetched. After all, there are many ways to make the child's family sad, such as dismembering the body or cutting off other parts of the body.

But the murderer chose the heart alone, which always makes people think that he has another purpose. If Luo Fei's speculation is followed, then this purpose makes sense.

"I don't rule out this possibility... There is another detail. I wonder if you have noticed it?"

"What details?"

"The child's chest was cut open and the heart was removed. Logically speaking, to do this, the child's clothes must be cut open or taken off to make it easier."

"But when the child's body was found, the clothes were intact, and there was only blood on the chest. This shows that the murderer took off the child's clothes before removing the heart. Then he deliberately re-clothed him when dumping the body. superior."

Luo Fei paused for a moment before continuing, "Don't you think this is strange? A murderer who is so cruel that he won't spare even a three-year-old child actually has the leisure to do such a cruel thing. Getting a child dressed is a very paradoxical thing in itself.”
