Criminal Investigation Notes

In the office of the serious crime team, the sun shines through the venetian blinds of the floor-to-ceiling windows, and the whiteboard in front of the desk is full of clues.

Su Hui continued: "We now know that the next potential victim's family is likely to be an active user on the forum, so they will definitely pay attention to the recent hot posts on the forum. Those victims talked over the air."

Qiao Ze was excited: "Mr. Su is very reasonable, so can we issue some warnings on the forum?"

Qu Ming shook his head: "Direct warning in such a large public forum will cause social panic. And we can't disclose the details of the case, this is against the regulations. And don't forget, while the victims are paying attention to the forum, , Those murderers are probably also looking at the text and data on these forums, once the murderer realizes the intention of the police and changes the way of murder, we will lose all our efforts."

Lu Jun said lately: "I agree with Qu Ming's statement that we can only carry out obscure one-way output."

Xia Mingxi frowned: "Then how should we write these posts?"

For a while, everyone was silent again. Su Hui's words seemed to show them a way, but it was very difficult to decide how to make good use of this.

Qu Ming thought for a while and said: "I think first of all, we need to add some safety popularization stickers, such as allowing them to change to safer door locks, popularizing household door openers, and one-button alarms; secondly, we need to teach them how to use mobile phones. Key alarm settings, frequently used contact settings; finally, privacy settings in mobile phones and computers are also very important, and moreover, some tips for popular science..."

This is also a warning method that ordinary people can think of.

Lu Jun nodded and said: "We can post these, and we can even contact the administrator to conduct a lottery for some safety protection equipment. But I estimate that many people may go to see it, or even queue up to check in and draw the lottery, but it is not necessarily true. will do it soon.”

The collective consciousness will not know the pain, only when the knife falls on the body of the individual will it feel it.

Su Hui thought for a moment and raised his head: "I think some psychological hints can be used. For example, using the recency effect. In this way, we can induce some subconsciousness through these hot posts."

Qu Ming asked, "What is the content and direction?"

"About family, persistence, love and sacrifice. If you want your victims to persevere and get enough rescue time, you must make them trust each other." Su Hui's voice was very calm.

In this era, when it comes to true love, there are always people who scoff at it.

Unmarriage is prevalent and the divorce rate is rising, but in fact, true love exists in every era, and there are many touching stories.

Love is not an ethereal thing.

If his previous analysis is correct, maybe love and persistence will be the countermeasures for those victims to face the robbers.

True happiness, true trust, is not displayed on the surface, but buried deep in people's hearts.

When encountering such an extreme and perverted gangster, the thoughts of each family member can decide their own destiny.

Lu Jun nodded his head late: "I think it's worth a try. Xia Mingxi, you can go to the Internet police to talk about it, then contact the website and choose some content to publish. Others hurry up and conduct big data screening on all registered users of Huadu on the website. check."

Xia Mingxi was stunned for a moment: "Team Army... I've been a mother's son for more than 20 years, and I don't know anything about feelings..."

Lu Junchi looked at his subordinates: "Then Xia Mingxi is in charge of communication. As for the content, Lao Qu can help you find it."

Qu Ming sighed in a hurry.

After the whole case has reached this point, Lu Junchi still feels that something is wrong.

The police are still passive, too passive.

The method Su Hui said was feasible, but it was only a shield for the last step of defense. It was the victim's self-rescue method, and it was a passive defense after there was no other way.

As the police, they can't sit still, they must do something, take the initiative to find those robbers, find these victims...

Lu Jun thought of this late and fell into deep thought. He turned to look at the whiteboard full of clues. There must be some way, but they haven't thought of it yet.

The other party was very careful and used a fake ID card, and the mobile phone card was not in his name. They have no good way to find them out of thousands of people...

Su Hui raised his head to look at Lu Junchi, who was standing not far from the whiteboard, leaning against the table. Although Su Hui couldn't see the details, he could feel that Lu Junchi's whole body was tense.

The detection process of each case is a process of solving puzzles and solving problems.

How else can they find those people as soon as possible?

Lu Junchi lowered his head and thought for a while, then raised his head and said, "Qiao Ze, you said earlier that the Lincheng police have confirmed one of their previous residences."

"Yes." Qiao Ze nodded, "but it was too late when they went, and the whole room was already empty."

Lu Junchi turned his head and said, "They must have left something somewhere..."

"But...the Lincheng police said they left nothing. The house was cleaned, the things were emptied, all the door handles were wiped, and the ground was mopped clean." Zheng Bai checked the information and wondered.

"I'm not talking about these actual evidences, but those illusory things..." Lu Junchi suddenly thought of something, his eyes flashed under his sword eyebrows, and he pressed his arms on the table, "such as those network data ."

Even the most cunning fox will leave its mark in the forest.

I don't know when it started, the Internet seems to be the oxygen that people live on.

Even those robbers must always go online and observe the world on the Internet.

The room can be cleaned, but the data left is kept in the operator's server and cannot be cleared.

They have been in Lincheng, Qincheng, and now Huadu. There are not many mobile phone numbers that fit such a trajectory.

They may have been connected to WIFI, they may have been connected to 4G, and they must have left clues in the operator's server, allowing them to find the person they are looking for from thousands of information data.

And this will be the sword they hold in their hands.

Lu Junchi arranged: "You and Lin Cheng and the police in Qincheng ask for assistance in the investigation, compare the dates of their contacts, and then conduct reverse tracking to see if you can find out the mobile phone numbers and computer equipment information used by these people. Mi Shu is a programmer and may add some settings, but Zhang Xiaocai and Qin Yongchen's awareness of prevention is not that high, so there shouldn't be too many precautions."

After hearing Lu Junchi's words, Su Hui couldn't help but feel moved, and turned to look at Lu Junchi.

His method is only to be able to assist psychologically, while Lu Junchi's method is a feasible means of criminal investigation. Although he does not know the technical steps required, he feels that this method should be feasible.

Lu Junchi pointed out the breakthrough point, and the entire serious crime team became excited.

They have mastered the location of the mobile phone number at a certain historical time, and can call up data, compare and find communication equipment, and perform reverse orientation. This is achievable in modern criminal investigation technology, but few people use it. in practice.

Qiao Ze was pleasantly surprised: "Army! It's completely feasible technically! It's just... This requires the cooperation of the mobile company to retrieve data, and we also need a certain amount of time."

Lu Jun said lately, "We will do our best."

We must prevent the tragedy from happening again.

At the end of the meeting, everyone immediately began to perform their duties and operate efficiently.

Now that the case has finally found the direction of detection, the next step needs to be implemented step by step, racing against time.

With the release of the wanted order, the serious crime team was divided into several groups. Zheng Bo was in charge of answering calls for clues, Qu Ming was in charge of screening the content posted on the forum, Qiao Ze inquired about the suspect's mobile phone information, and Xia Mingxi was in charge of cooperating with the Internet police and forum moderators. Communicate and complete network information release.

Xia Mingxi, a straight girl of steel who is insensitive to feelings, couldn't help but see tears in her eyes after posting several rounds of posts. After get off work, she also transferred a few posts to the work group of the General Administration: "Everyone must watch it. , 5555555, so touching, I can believe in true love again."

Several policewomen were discussing, and the male compatriots followed: "What, Xiaoxia, have you finally figured it out?"

"Do I have a chance?"

"It's nothing to be moved by reading the post, I'll show you the true love in the world!"

"Xiao Xia, are you asking for a public marriage?!"

"I can do the things in the post! I'm missing a girl now!"

Xia Mingxi jumped in the group: "What is needed to investigate the case! Don't think too much!"

Lu Jun came out of the shower late, wiped his hair with a towel, and looked at his phone with one hand. He snorted when he saw this passage: "I thought Xiao Xia was enlightened..."

80% of the little policemen in the group are single, they work very seriously on weekdays, and they have a lot of discipline. Their skills in chasing girls are really poor. Before these eight characters were written, the Shanmeng Sea oath was issued first.

Su Hui was sitting on the sofa and was also looking at his mobile phone. He was forced into the group by Qiao Ze and the others, and he kept diving in it. At this time, he couldn't help but commented when he saw the screen and commented: "It's all driven by some hormones. Nonsense, too low-end..."

Lu Junchi asked, "Mr. Su, what do you think is a high-end pursuit?"

Su replied: "Well, of course, you have to check the password first."

He put down the phone and said seriously, "During the courtship process, there was a moment, maybe it was an action, maybe it was a sentence, maybe it was a look, one thing. If the code matches, it means you and The other party is of the same kind, and you have the opportunity to further develop. It doesn't take long to confirm this point, and it really only takes a moment to like someone. That's why it is said that it is love at first sight."

Lu Junchi asked: "Then you believe in love at first sight?"

"The same is true of love after a long period of time. The so-called love for a long time is the accumulation of countless moments, resulting in qualitative changes caused by mass production. In short, with this point, you can have subsequent development. Without this point, you are dead. Stalking is useless, it will only make the other party more and more disgusted." Su Hui was as serious as he was discussing academic issues.

Lu Junchi's heart moved, thinking of a certain moment, he asked again: "Then what?"

"Then we have to take a slow approach, start with communication, then start with hobbies, but this is just a theoretical analysis." Su Hui said here, raised his head to look at Lu Junchi, his eyes flashed, and finally fell on Lu Junchi's waist.

Only at this time did Su Hui realize that Lu Junchi's T-shirt was white and thin, almost sticking to his waistline. His eyes are not good, but even if he is blind, he can see that Lu Junchi has a superior figure. He even remembers the temperature when he was close to his body before. He glanced at it and turned his head sideways.

Lu Junchi didn't realize that Su Hui was looking at him at all, he just asked casually, and now he wiped his hair, lowered his head and carefully flipped through the posts made by Xia Mingxi: "There is already a heated discussion on the forum, and several Post with HOT."

Su Hui said: "It would be good if it can be effective..."

"Even if I read those stories, I will feel the subtle influence on my concept." Lu Junchi liked the story of the snow mountain couple. The two supported each other and left the hope of life to each other. He suddenly remembered something and lifted it up. He started to ask Su Hui, "Mr. Su, have you ever been in love?"

Su Hui hesitated for a moment, then shook his head.

From his birth to the present, he has had many suitors. He has received confessions from many girls, as well as men. But since two years ago, he seems to be insulated from love.

Lu Junchi asked again: "Then you must believe in true love when you raise this opinion today, right?"

Su Hui suddenly panicked, coughed a few times, and asked indifferently, "Ah...that...love is one of the very important emotions of human beings."

In fact, those human emotions are now in his blind spot.

Su Hui never questioned the existence of such a thing as true love.

It will exist between some people.

He can unscrupulously dissect the worldview of those criminals, describing the sex, madness, love, ideas in their world.

But Su Hui didn't believe that a good love would happen to him.

Su Hui thought about it, and for some reason, felt a little pain in his chest again...
