Criminal Investigation Notes

In the office of the serious crime team, the sun shines in 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 air."

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

Qu Ming shook his head: "Direct early warning in such a large public forum will cause social panic. And we can't disclose the details of the case, which is against the regulations. And don't forget, when the victim pays 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 method of attack, our previous efforts will be in vain.”

Lu Junchi said: "I agree with Qu Ming's statement, we can only carry out one-way output in a subtle way."

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

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

Qu Ming thought for a while and said: "I think first of all, we need to add some safety science posts, such as allowing them to change to safer door locks, popularizing household door jacks, and one-button alarms; Key alarm settings, frequently used contact settings; finally, the privacy settings in mobile phones and computers are also very important, and moreover, popularize some fighting skills..."

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

Lu Junchi nodded and said: "We can post these, and even contact the administrator to conduct a lottery for some safety and protective equipment. But I estimate that many people may go to see it, or even line up to check in and draw a lottery, but it may not be true. will do it right away.”

Group consciousness will not know pain, only when the knife falls on an individual will it feel it.

Su Hui raised his head after thinking for a moment and said, "I think we can use some psychological hints. For example, using the recency effect. In this way, we can use these hot posts to induce some people's subconsciousness."

Qu Ming asked, "The content and direction?"

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

In this day and age, when it comes to true love, some people always scoff at it.

Unmarriageism 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 illusory thing.

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

True happiness and true trust are not suspended on the surface to show off, but buried deep in people's hearts.

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

Lu Junchi nodded: "I think it's worth a try. Xia Mingxi, go to the Internet police to talk about it, then contact the website and choose some content to publish. Others hurry up and screen all the registered users of Huadu on the website with big data check."

Xia Mingxi was stunned for a moment: "Captain Lu...I've been a solo mother for more than 20 years, and I don't know anything about relationships..."

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 hurriedly.

The whole case has gone so far, but Lu Junchi still feels that something is wrong.

The police are still passive, too passive.

He thinks the method Su Hui mentioned is feasible, but it is only a shield for the last step of defense, a way for the victim to save himself, and a passive defense after there is 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 Junchi thought of this and fell into deep thought. He turned his head and looked 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 looked up at Lu Junchi, who was standing not far from the whiteboard, leaning against the table.Although Su Hui couldn't see the details clearly, 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.

Is there any way for them to 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 empty."

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

"But...the Lincheng police said that they left nothing behind. The house was cleaned, everything was emptied, all the doorknobs were wiped, and the floor was mopped clean." Zheng Bai checked the information and wondered.

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

Even the most cunning fox leaves its mark in the forest.

I don't know when it started, the Internet seems to have become 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 remaining data is kept in the operator's server and cannot be cleared.

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

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

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

Lu Junchi made arrangements: "You and the police in Lincheng and Qincheng request a co-investigation, compare them with 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. .Mishu is a programmer and may add some settings, but Zhang Xiaocai and Qin Yongchen's awareness of prevention is not so high, so they should not have too much defense."

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

His method can only provide psychological assistance, while Lu Junchi's method is a feasible method for criminal investigation. Although he doesn't know the technical steps required, he thinks 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 in a certain period of time, and can call up the data, compare and find communication equipment, and perform reverse orientation. This is possible in modern criminal investigation technology, but few people use it. in practice.

Qiao Ze said pleasantly: "Team Lu! Technically speaking, it is completely feasible! It's just... this requires the cooperation of the mobile company to retrieve the data, and we also need a certain amount of time."

Lu Junchi said: "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, the case has finally found the direction to be solved, and the next step needs to be implemented step by step, against the clock.

With the release of the arrest warrant, the Serious Crime Squad was divided into several groups. Zheng Bai was in charge of answering clue calls, Qu Ming was in charge of screening the content posted on the forum, Qiao Ze was in charge of checking the suspect's mobile phone information, and Xia Mingxi was in charge of communicating with the Internet police and the forum moderator. Communicate and complete network information release.

Xia Mingxi, as a steel straight girl who is insensitive to emotions, couldn't help but shed tears after posting a few rounds of posts. After work, she also transferred a few posts to the work group of the General Administration: "Everyone must read , 5555555, so touching, I can believe in true love again.”

Several female police officers discussed heatedly, and the male compatriots followed suit: "What, Xiao Xia, you finally want to open your mind?"

"Do I have a chance?"

"It's nothing to be touched by the post, I will prove the true love in the world to you!"

"Xiao Xia, are you asking for marriage publicly?!"

"I can do the things in the post! Now I need a girl!"

Xia Mingxi kept jumping in the group: "What you need to investigate the case! Don't think too much!"

Lu Junchi came out of the shower, wiped his hair with a towel while looking at the phone with one hand, and heheeded when he saw this part: "I thought Xiaoxia had gotten better..."

80% of the little policemen in the group are single, and they work very seriously on weekdays, and there are many disciplines, and their skills in chasing girls are really clumsy.Before the horoscope was written, the vows of the mountain alliance and each other were issued first.

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

Lu Junchi asked: "Then Teacher Su, what do you think is the high-end pursuit method?"

Su replied: "Well, of course we have to answer the code first."

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

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

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

Lu Junchi's heart skipped a beat, recalling a certain moment, he asked again: "Then what then?"

"Then it's time to strategize slowly, starting with communication first, and then starting with hobbies, but this is just a theoretical analysis." Su Hui raised his head to look at Lu Junchi, his gaze flickered, and finally landed on Lu Junchi's waist.

Only then did Su Hui realize that the t-shirt Lu Junchi was wearing was white, very thin, and almost stuck to his waistline.His eyesight is not good, but even if he is blind, he can still see that Lu Junchi has a superior figure. He even remembered the temperature when he was close to his body before. He took a few glances and turned his head sideways.

Lu Junchi didn't realize that Su Hui was looking at him at all. He just asked casually just now. Now that he had wiped his hair, he lowered his head and carefully looked through the posts posted by Xia Mingxi: "There is already a hot discussion on the forum. Several Post added HOT."

Su Hui said: "It's good to have an effect..."

"Even if I read those stories, I will still feel the subtle influence on my concept." Lu Junchi likes the story of the snow-capped couple among them. The two support each other and leave the hope of life to each other. Start by asking 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 no shortage of suitors. He has received many confessions from girls, and men have also.But since two years ago, he seemed to be insulated from love.

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

Su Hui panicked all of a sudden, coughed a few times, and asked irrelevantly: "Ah... that... Love is one of the most important emotions in 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 certain people.

He can unscrupulously analyze the worldview of those criminals, and describe the sex, madness, love, and ideas in their world.

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

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