Evidence hunting forensic 4 unsolved case code

The whole morning, Lin Dong spent his time researching the comment section of every new drug popular science video on the video platform.He has an idea: since Tan Xiaoguang can find out a drug dealer from the replies, then there may be other interested people who browse these videos, and among these people may be the criminal suspect of using "stamps" to kill Chen Jun people?

According to Luo Jianan's early reconnaissance and recent investigations, it is certain that the woman in the sunflower skirt went after Chen Jun. At first, it was deduced that the nature of the case was an "accident" caused by a special industry service provider or a professional drug dealer. "There is a deviation.This is a typical premeditated crime.One of the characteristics of premeditated crimes is that there is sufficient planning and preparation in advance, and it is a very convenient means to obtain the required information, professional knowledge and even crime tools through the Internet.It's just that there are tens of thousands of replies, and a lot of useless information is mixed in, so it's really hard to find useful things in a while.

At this time, Yangkelin will be used, but Yangkelin can't do anything if there are no powerful keywords.Lin Dong researched the replies in order to find out some keywords, and then use these keywords to filter the massive replies, so as to be targeted.Big data can facilitate the detection of cases, but the programs are written by humans. The calculation models and keywords that can identify suspects from the vast ocean of data come from the extraordinary wisdom of the investigators and are the result of experience and technology. perfect combination.

In a broad sense, this can be regarded as the portrayal of suspects, and it is fashionable to call it criminal profiling.Criminal profile is translated from criminalprofile, literally translated as a criminal profile, which is equivalent to the portrait of a suspect in the mouth of an old police officer. Profile is a more literary term.He learned criminal profiling when he was studying in Canada, and he used it habitually for a while after he came back, but he was despised by the old policeman, so he turned back.

Most of the old police officers have the ability to understand the behavior of criminals. When he first started to conduct criminal investigations with Tang Kui, he was often shocked by the other party's analysis of what the suspect did at the scene and what he did after he left the scene.To exaggerate, it is like installing a surveillance camera on the suspect.For example, in a case of intentional injury, the victim was attacked on the way home, and was suffocated with a stick on the spot, lying half dead in the ICU, unable to ask a word.Tang Kui wandered around the scene, turned his face and took the "enthusiastic people" who called 120 back to the bureau. In the first trial, it was indeed the black hands of this buddy.As for why this person was arrested, Tang Kui said that based on the situation at the scene, the murder weapon was a stick picked up casually, which was a crime of passion. An ambulance was called.

The suspect’s confession was almost the same as what Tang Kui imagined: the two didn’t have a deep hatred, and they didn’t even know each other; it was only because of a little unpleasantness at the checkout in the supermarket, and the suspect had just been fired by the unit, full of resentment and anger Then he followed the victim, went to a place where no one was around, picked up a stick and swung it at the opponent; after the person stopped moving, he was also dazed, ran out for a while, and came back again to see if the person was dead or not. Finding that he was still alive, he chose to call 120 for an ambulance under all kinds of entanglements.

In the end, this person paid a painful price for his momentary happiness, and sadly recalled his dream of being behind bars for ten years.Returning to the case in front of him, Lin Dong had a speculation similar to Tang Kui's at the beginning: he gave Chen Jun medicine, not necessarily to kill Chen Jun, because LSD is essentially a drug, hallucinogenic but not lethal, because the cause of death is basically Caused by hallucinogenic behavior, such as jumping off a building and self-mutilation.And the behavior after hallucination is unpredictable. If he really wanted to kill Chen Jun, it would be difficult to achieve the desired result with LSD. Moreover, there was no record in his medical records that he had an aneurysm, so it was impossible for the suspect to foresee it. Chen Jun's blood pressure rose sharply after taking the medicine, which eventually led to the rupture of the tumor.

With complicated thoughts spinning in his mind, Lin Dong wrote the replies one by one.Suddenly a paragraph of text jumped into view, he stared at it for a while, picked up the cigarette and lighter on the table, and walked out of the office.Standing still in the safe passage, he lit a cigarette and dialed Tan Xiaoguang's cell phone.

"What's the matter, Team Lin?"

The tone over there sounded relaxed, and a little bit unconcealably happy.Thinking that the shackles that have been carried for many years can finally be unloaded, everyone will have to be happy for a few days.It was the same for Lin Dong back then, when he learned that his brother did not deliberately die the members of the team, he felt as if he had been reborn.But the death of his comrades is a real regret and shock. In the dead of night, he would still cry sadly looking at their photos.

"Well, let me ask you something professional." Tan Xiaoguang's case was overturned, the main credit lies with Lin Dong, so he summoned the other party to do whatever he wanted, "LSD is also called 'Veritaserum', isn't it?"

Tan Xiaoguang agreed: "Ah, it is said that this thing was first used by the CIA for interrogation, and it came out of their hands. The official statement is that they refuse to admit it. Hey, where did you find it?"

Can you admit it?Lin Dong frowned and smiled: "I saw a reply post under your video. People asked you that, but you didn't respond."

"I usually don't care about this kind of thing. We haven't studied it. I don't know if it has the effect. It's not easy to talk nonsense. Besides, I'm a new type of drug science video. It's about harm, just in case anyone who wants to—" said Then, he suddenly paused, seemed to realize something, and then said in a serious tone: "What do you mean? Do you think someone saw the problem after watching the video I posted?"

"No, I'm investigating a case involving LSD. What I'm thinking is, since you can catch the drug dealer from the replies, then..." After a pause, Lin Dong solemnly said: "The suspect I'm looking for may also be Leave a message below and ask for relevant knowledge.”

There was silence on the other end of the phone, and it took a while for a sigh to come: "It's going to kill me, I sent a video and stabbed the nest of drugs."

"Don't think so, the video you made is very meaningful. Many people understand it after watching it, and they have a heart of defense to avoid going astray." Lin Dong sincerely gave the other party affirmation and comfort, "And the commentary is very well written. Interesting, not boring to watch, entertaining and educational at the same time."

This is not flattering. Compared with Qi Ming's videos that have been blocked by the platform one after another, Tan Xiaoguang's videos are true and can be called entertaining.For example, in the ice/drug issue, one of the lines impressed him deeply—"This thing will trick your brain, making you think you can beat a bear, but in fact, the bear in your eyes is your mother" , There is also the second issue about marijuana. There is a sentence in the commentary that "Those who posted bullet screens told me where marijuana was legalized. If you have the guts to go to your city's public security bureau to see what's on the wall of heroes." Photos, make a familiar face, and guarantee to line up at night to discuss life with you!".

Tan Xiaoguang swept away the depression just now, and laughed loudly: "Hahaha, that was all written by Zhuang Yu, isn't it fun? I often laugh when I record."

Written by Zhuang Yu?Lin Dong couldn't believe it for a while.I really can't see that the guy who keeps a straight face all the time and doesn't even crack a joke has such a funny side.

The author has something to say:

Erji: Teacher Qi’s commentary on the video let Brother Nan write it, which may attract more fans, um, change the cover, change the soundtrack...

Teacher Prayer: No pulling or trampling!
