Criminal Investigation Notes

Early the next morning, as soon as Xia Mingxi arrived at the Serious Crime Squad, he found that the layout of the office had changed. There was a large long sofa on the left side of the entire office. A throw pillow and lumbar support.

It is not so much a sofa as a bed. The entire sofa is more than two meters long, allowing an adult to lie flat and still be rich.

Xia Mingxi looked at Qiao Ze curiously, pointed to the sofa: "This is..."

Qiao Ze said: "Oh, the sofa was requested by the logistics team and me. It was said to be used for rest during overtime work. It was just delivered this morning."

A few people worked overtime until midnight yesterday, and they all had dark circles under their eyes today. Fortunately, the investigation of the case has finally made significant progress.

At this time, several team members seized the time to gossip before Lu Junchi came.

Zheng Bai walked over and sat down on the sofa. The sofa has good springs and just the right amount of softness: "Oh, Captain Lu is so kind, I know how to be considerate of my subordinates. I've long been envious of the people in the criminal police team getting up and down on the bed. , everything on duty is easy to use, and now that we have the equipment, we can at least take a nap when working overtime.”

Qiao Ze held the steamed buns in his mouth: "We didn't even have much time to lie down. Besides, when you were on duty, you often rubbed against the bed of the criminal police team."

There are not many of them, and there is not much vacancy in the office. It is really unnecessary to apply for a bed, but the meaning of the sofa is different.

Qu Ming pointed out in a low voice: "Captain Lu, this is pity and pity..."

Then Zheng Bai suddenly realized: "Oh, I remember that Teacher Su is not in good health, so we are under the influence of Teacher Su..."

Xia Mingxi held his chin: "I don't know if Captain Lu will be so considerate to his girlfriend."

After hearing this, everyone turned their heads to look at Xia Mingxi.

Xia Mingxi was terrified by everyone's eyes: "Ah, why, did I say something wrong?"

Right at this point, Zheng Bai looked towards the door: "Team Lu is here, shhh..."

The gossip stopped immediately.

Lu Junchi stepped in quickly, Su Hui followed behind him, and Lu Junchi sat down at his desk.Su Hui's eyes fell on the sofa all of a sudden. He put down the scepter, walked over to sit on the sofa to try it out, and even picked up a pillow and hugged it in his arms. His movements were as skillful as if he was embracing it. Like a cat.

Lu Junchi looked at Su Hui, and felt that this person was also like a cat, and he had the same virtue as Aristotle, so he could directly use a sofa as a cat's litter.

Seeing that everyone is here, Lu Junchi said: "Let's hurry up and collect all the information about the suspects in this case."

As soon as his voice sounded, the lively atmosphere in the entire office was immediately swept away, and everyone became tense.Lu Junchi called his name and said, "Qu Ming, let me tell you about the results of yesterday's comparison."

"Yes." Qu Ming responded, and hurried forward with several stacks of documents, "We have now confirmed the identities of the three robbers. First, let's talk about the male robber. Based on the clues obtained from various sources, we retrieved the list of survivors of major domestic fires in the past three years and compared their identity information. Sure enough, we found a person who matched the appearance of the robber, thus confirming the identity of the male robber .”

While talking, Qu Ming pasted a male photo on the whiteboard in the office.It was an enlarged standard photo of an ID card. The person in the photo had a dark complexion, his brows were furrowed, and he looked gloomy. He looked very similar to the man captured in the surveillance.

"Qin Yongchen, male, 34 years old, 1 meters tall, graduated from a junior college, he was a trainer in a fitness center before, and was burned in the 82 Decheng supermarket fire two years ago."

Xia Mingxi let out a sigh: "I remembered, I seem to know this person..."

Qu Ming nodded and continued: "I think many people should have seen the news. When the fire broke out, Tan Yongchen and his girlfriend who had been with him for five years were on the fourth floor where the fire was the worst. He and his girlfriend walked away in the fire. After escaping from danger, Tan Yongchen found that his girlfriend hadn't come out, so he ignored people's dissuasion and returned to the fire to find his girlfriend."

When Qiao Ze heard this, he suddenly thought of something and said, "I saw it too. It seemed that many media reported it at that time..."

"Before the firefighters arrived, Tan Yongchen rescued his girlfriend, but he himself was fainted by the thick smoke. At this time, his girlfriend chose to escape by himself and escaped from the fire. His girlfriend was almost uninjured. Tan Yongchen was burned He was seriously injured and almost died. At that time, 60% of his body was burned and he was admitted to the ICU. The matter of Tan Yongchen rescuing his girlfriend in the fire became a hot topic of discussion for a while. And his girlfriend was arrested because she abandoned him. Numerous people condemned."

Su Hui couldn't see the photos on the whiteboard clearly for a while, hugged the pillow, and listened carefully. He didn't pay attention to these social news during that time, or he didn't notice it at all.However, such an experience was in line with his psychological test of the criminal.

Xia Mingxi said: "I remember his girlfriend said at that time that if she stayed, she would probably be burned too. It is human nature to escape before danger, but in short, he was scolded miserably. Later, to save Tan Yongchen, I remember crowdfunding coming."

Qu Ming said while pasting information on the whiteboard: "At that time, Tan Yongchen was seriously injured, critically ill several times, stayed in the ICU for a long time, and was repeatedly infected. At that time, some kind-hearted people heard about Tan Yongchen and told him There were people who donated to crowdfunding, and some people came to visit him specifically, but the enthusiasm for this matter did not last long, and was soon overwhelmed by other news."

Lu Junchi asked: "Then what happened?"

Qu Ming continued: "Tan Yongchen's parents have passed away. My brother and sister-in-law don't think it's a good thing for him to save others. Instead, they think that he is dazed by love, refuses to pay the medical expenses and wants to sever ties with him. At this time The girlfriend who was talking about marriage changed his mind at home and no longer agreed to the marriage. Later, the girlfriend simply moved away. The charity funds raised by crowdfunding were just a drop in the bucket. Tan Yongchen faced high debts alone and lost his job. Treatment It took a long time to get better, his body was burned extensively, and he had no money for skin grafting, so the treatment had to be terminated."

Qiao Ze heard this and said, "No wonder Tan Yongchen was dressed in black every time the surveillance captured him, covered him tightly, and wore gloves. It turned out that it was because of burns..."

"After being discharged from the hospital, Tan Yongchen contacted many ways and found his ex-girlfriend. He stopped her outside the ex-girlfriend's company and questioned her. There was some pushing and shoving between the two of them. All this was recorded by passers-by. Then it was posted on the Internet."

Zheng Baidao: "I said, why does this person look so familiar? I've seen that video... He was threatening his ex-girlfriend. I seem to have said a few words on the Internet at that time..."

Qu Ming nodded: "This time, the people who supported Tan Yongchen at that time turned their backs one by one. Most of them thought that he should not continue pestering the girl, and he was already viciously harassing the girl. The mainstream voice on the Internet is that boyfriend saves girlfriend , Shouldn’t it? He went back to save his girlfriend voluntarily. As an adult, he should bear the consequences of this incident. Now that they have broken up, they should not continue to entangle. Some people say that Tan Yongchen is now It's disfigured, and the girl shouldn't force her if she doesn't want to. Even if a few people accuse the girl of being ungrateful to her savior and being unfeeling and indifferent to her ex-boyfriend, they will soon be overshadowed by other voices..."

"The netizens scolded him very harshly, and even scolded him why he was not burned to death. Tan Yongchen also started to scold them. He argued with people on the Internet for a long time, and later even began to insult some neutral people who even sympathized with him. Netizens, many people thought he was crazy. Later, Tan Yongchen once went to find his ex-girlfriend with a knife, and was stopped by security guards and passers-by. His girlfriend called the police, and he was sentenced for a period of time. After he was released from prison, He was never seen again and he disappeared from the public eye."

When Su Hui heard this, he said, "Show me the post he was arguing with others at that time."

Qu Ming had sorted it out a long time ago, and handed a stack of documents to Su Hui. Su Hui looked at it with a frown, hoping to sort out the trajectory of Tan Yongchen's psychological changes from those remarks.

Su Hui found that at the beginning, the arguments between him and those people were mainly about the right and wrong of the matter.

Was it right or wrong for Tan Yongchen to save his girlfriend?

Is it right or wrong for a girlfriend to dump him?

Tan Yongchen thought that his own actions were just, and his girlfriend's actions should be condemned and punished. His injuries were all because of his girlfriend. If he hadn't gone back to save her, she would have died long ago.

His girlfriend's escape from the scene was the first injury to him, and abandoning him afterwards was the second injury to him.

She should be punished, or compensate him.

But obviously, my girlfriend and most netizens don't think so.

In the end, Tan Yongchen was overwhelmed by these discussions. He was full of hostility and began to attack and abuse indiscriminately.

Tan Yongchen even suggested that those who betray and abandon their loved ones in times of crisis deserve death.

In such a situation, there is no one to support him.

Then Qu Ming posted a photo of a woman with short hair on the whiteboard: "This woman is called Mi Shu. She is 32 years old and 1 meters tall. Mi Shu used to be a female programmer for an Internet company. Before Tan Yongchen disappeared, she I visited him in the hospital and gave Tan Yongchen some help, we compared it with the recent surveillance, she should be the woman among the robbers."

The woman in the photo has short hair, is very thin, looks quiet, beautiful, smart and capable.

"After being reminded by Teacher Su, we checked some information and found that Mishu was the victim of a case three years ago. One night in August of that year, Mishu and her ex-husband were walking on the street and met three The gangster, the gangster whistled at Mishu at first, then there were some frictions and quarrels, her husband left her and ran away, and Mishu was dragged to the side of the road by those three men to defile her."

This is a somewhat sad story. The man who was supposed to protect the woman escaped first.

Zheng Bai couldn't help but said: "Such a man is too useless."

Qu Mingdao: "Even afterwards, Mishu himself reported to the police. Later, some netizens scolded Mishu's husband on the Internet. The man said that if he stayed there, he would probably be killed. His life was in danger. , it is human nature to run away.”

Qiao Ze was filled with righteous indignation: "It's human nature again? Then you can't just leave your wife and run away... I think this man who left his wife should really go to jail." Then he said with a snort, " This seems to be related to Tan Yongchen's previous concept, no wonder these two people came together..."

Xia Mingxi pursed her lips, and said as the only girl present: "From a moral point of view, you can condemn her husband, but from a legal point of view, you can only say that he did not fulfill his husband's obligations, which constitutes a civil tort. Whether he has violated the criminal law or not? You have to understand the specific situation before making a decision. This kind of thing needs to be looked at, as the saying goes, husband and wife are like birds in the same forest, and they will fly separately when disaster strikes."

Su Hui was silent after hearing this passage.

Lu Junchi asked, "Qu Ming, have you contacted her family?"

Qu Ming nodded: "I contacted Mishu's family early this morning, and the family said that she had resolutely divorced after that incident, and then quit her job. She said she wanted to be alone and cut off contact with all relatives and friends. As for how she and Tan Yongchen got together, it is still under investigation."

"About the No.3 bandit..." Qu Ming took out another photo while talking.

In the photo is a teenager with a few strands of hair dyed, and he still looks a little childish.

"Zhang Xiaocai, male, his parents divorced when he was young, and his mother formed a new family after remarriage. His father also regarded him as a burden, and often beat and scolded him. He ran away from home and lived alone on the street, picking up trash as a living Health. Zhang Xiaocai has been in juvenile detention centers many times since he was 14 years old. He and other habitual thieves learned to pick locks. He is known as Zhang Locksmith. He can open the door locks of ordinary families in a few seconds at the fastest. Although he is young, But he's a veteran thief."

With someone like Zhang Xiaocai, these three robbers could break in at any time.

Men, women, and teenagers correspond to husbands, wives, and children.

They came from different families and suffered different traumas, but they hugged each other for warmth and formed a temporary family.

It was these three people who raised their knives to ordinary people, making every family shudder.

But no matter how painful the experience is, it should not be a reason for evil.

Lu Junchi looked at Su Hui. Su Hui had already finished reading the materials of Tan Yongchen's debate with netizens. He sat on the sofa beside him, crossed his legs, lowered his head and concentrated, thinking about the case.

Now, the identities of the three robbers have been verified, and there are many overlaps between the criminal's life experience and what he predicted yesterday.

abandon.

All three were abandoned by their families or so-called lovers.

Mi Shu was hurt because her husband abandoned her, Tan Yongchen was also abandoned by his girlfriend and family, and Zhang Xiaocai was even abandoned by his parents since he was a child.

They see each other as family.

In their thinking, those who abandon their lovers or family members in times of crisis deserve death.

They are using massacres to vent their depression.

Lu Junchi read all the materials, nodded after confirming that they were correct, and said, "Xia Mingxi, I'm going to apply for a warrant. Everyone needs to catch these three people before they commit another crime."

Xia Mingxi said, "Yes."

Now that the robber's identity information has finally been clarified, the most critical part has been completed.

However, there is still a certain distance from catching the robbers.

These people must be using fake IDs now, and they are now hidden in a huge city, so it is not easy to find out.

"Open the citizen reporting hotline, and you can apply for a certain amount of money as a clue bonus." Lu Junchi thought for a while and added, "These three people should be working in a group, and they are likely to live together, and it is an old community or a homestay. One category, print and distribute some circulars to each branch.”

Then he turned his head and asked, "Joze, is there any result in your information collection about the victim?"

Qiao Ze said: "There are some discoveries, we seem to have discovered a common feature of all the victims."

Lu Junchi asked, "What is it?"

"Among the several victims, all of them had an account of Xingfu Family and posted posts on it. Several of them were still active users on it, and they had many refined posts. I retrieved the accounts of several victims. Internet records, this forum, they log in almost every day, I don’t think it’s a coincidence.”

"Happy Family?" Su Hui had never been to this website, he was afraid that he hadn't heard clearly, so he frowned and repeated.

Xia Mingxi explained: "Happy Family is a very large community with as many as 18 million registered users. It is mainly aimed at women aged 50 to [-]. There are many sections on blind dates, mother-in-law and daughter-in-law, gossip, mother and baby. And The families of these victims have all made public posts."

"More importantly..." Qiao Ze said and took out another piece of information, "At the beginning of last year, the Xingfu family had a serious data loss, including user data information. Especially this forum Real-name authentication is required when registering, and there are many activities where you can win real prizes, and you need to fill in your home address and mobile phone number.”

"Mishu used to be a very good female programmer. According to her former colleagues, her technology is better than many male colleagues. She may have obtained the data package of the forum through some channels."

So after the data is lost, users feel that they are safe wearing vests, but in the eyes of hackers, the data of those users is tantamount to transparency.

They can obtain their specific location, phone number, real name, and even ID number.Coupled with the photos they posted, the privacy of these people was completely exposed inadvertently.

Qu Ming was surprised: "In other words, the robbers probably obtained the victim's information through this forum?"

Su Hui put down his pillow when he heard this, sat up straight, and said softly: "Organized premeditated crime..."

The murderer's choice of victims is not random, but purposeful and screened.Every murder seems intricate, but in fact it also hides a mystery.

The families of the victims got attention because of the bragging posts.

They basked the netizens about their happy family and happy life.

But jealousy shines through the screen into reality.

These three people not only had their own roles in the crime, but also cooperated with each other in the early stage. They traveled to many places and killed many people.

These people are using killing to tell the world that the so-called happiness is an illusion, and how vulnerable the love in the family is in the face of life and death.

Qiao Ze continued: "However, judging from the forum data we have obtained so far, there are millions of registered users in this forum in Huadu, and the previous victims have all posted posts in the daily area. Among the current active users who are limited to the daily area, there are probably no less than tens of thousands of people."

For a while, everyone was silent.

The office was quiet, except for the slight rustling sound from the air outlet of the air conditioner.

It took only a few days to take over the case from the serious crime team. They have gradually approached the robbers, learned their true identities, and their criminal motives.

This kind of speed of solving the case is already very fast, which is beyond the reach of other criminal investigation teams.

But this speed is not enough, the robbers have not yet been brought to justice, and new victims may appear at any time.

Behind these tens of thousands of users are tens of thousands of families. Among these potential victims, who will be the next one?

If this is a fight, they need a breakout now.

Lu Junchi said: "Further analyze the characteristics of the victims in the past, try to use big data to filter and narrow the scope."

Su thought about it and said: "Although we can't determine who will be the next victim, I think we can make some attempts..."

Everyone turned their heads in unison, and all eyes were on Su Hui for a while.

Su Hui propped his chin with a white hand and said, "For example, we can try to have an air conversation with our potential victims through the forum."
