"Luo ...... The Lokar principle?" Gao Desheng was stunned, feeling confused.

To be honest, he hadn't heard of it at all.

Gu Chen said this, but it would make Gao Desheng even more entangled.

"Ahem. Officer Wang, who was sitting opposite, couldn't help coughing dryly, and then said: "Lokar's law of material exchange tells us that as long as the perpetrator commits a criminal act, he will inevitably act directly or indirectly on the object of infringement and its surrounding environment at the crime scene, and will consciously or unconsciously leave traces. ”

Looking up at Gao Desheng, Officer Wang raised his eyebrows and said, "The general view is that 'traces' in a broad sense include material traces and consciousness traces. ”

"Yes. Gu Chen nodded silently, and said: "As early as the 50s of the last century, Professor Xu Ligen's translation of the "Theory and General Method of the Same Identification of Criminal Countermeasures" written by the former Soviet scholar Vaya Kerkin proposed that all kinds of reflection images can be divided into two categories. ”

Yuan Shasha was stunned, and hurriedly asked Gu Chen, "Senior Brother Gu, what are the two types?"

Gu Chen said with a light smile: "The first category of reflected images is the materially fixed reflected images, such as handprints, footprints, traces of means of transportation, animal traces, traces of tools and instruments, traces of stamps, printed and hand-copied texts, photographs, and so on. ”

"The second type of reflection image is the result of the person's sensory perception of the identified object, for example, it is more appropriate to retain the person who witnessed the crime, which can also be called the 'scene perceiver'. ”

"But in my memory, with regard to the specific sensory concepts of the characteristics of people or things, I think that, in addition to the above two traces, there should be a third trace, that is, the traces of the criminal mind. ”

Looking at Gao Desheng, who was trembling in front of him, Gu Chen said again: "The Lokar principle tells me that every contact will leave traces, which is very important in the case. ”

"You Gao Desheng, although you didn't leave any fingerprints at the scene, He Ling left a hair in her CD case. ”

"With our DNA technology, you can't prove that you weren't at the scene at the time of the crime, after you rule out the possibility that anyone else was at the scene. ”

After a pause, Gu Chen said again: "You didn't leave any fingerprints at the scene, at least not the fingerprints that we can confirm, but the fingerprints He Ling left on her stolen CD bag are enough to prove that you have been to her home." ”

Continuing to put the various crime tools that he had searched from Gao Desheng on the table, Gu Chen said again: "And these crime tools, don't you tell me, you are wearing this kind of hood and holding these trick tools, just to play a prank? You are clearly looking for a target to wait for an opportunity to commit a crime." ”

"Comrade policeman, I ......" Gao Desheng panicked at the moment, and didn't know how to answer for a while.

Gu Chen didn't hope that he would admit it immediately, so he said: "Also, we use monitoring equipment, according to your activity trajectory in Xiaoshan Town in the past few days, you seem to often wander around He Ling's house, what are you trying to do?"

"It's just stepping on a point. Officer Wang took a sip of wolfberry tea, and said angrily: "You were the first day we were a policeman? With your behavior, we knew at a glance what you wanted to do? and you pretended to be innocent with me." ”

"Gao Desheng. Lu Weiwei was also furious and said: "You have stolen and killed, what else do you have to say? Let me tell you, there is a lot of evidence left on He Ling's body." ”

"Don't think that we can't detect the traces on your body, I advise you to be kind, or give me everything that should be explained. ”

Gao Desheng also panicked at the moment......

He knew that he couldn't give a reason to defend himself, and there was no point in resisting stubbornly, so he could only bow his head and admit: "No ...... Yes, I killed that woman, but I didn't mean to kill her, I ...... I also had a bad idea and my brain cramped. ”

"Make it clear. Seeing Gao Desheng's incoherent words, Gu Chen raised his head and prompted.

"Comrade policeman, I ...... I'm just a thief, I usually steal something, I didn't think about killing anyone, that night, I really didn't know anyone in the house. ”

"Have you been paying attention to He Ling's family for a long time?" asked Officer Wang.

"Also...... It wasn't for long, either. Gao Desheng lowered his head and said truthfully: "When I stepped on this community before, I found that this family, oh, is the He Ling family you are talking about, and she is the only one who lives. ”

And strangely, she had to go out every night, almost late. ”

"I guess it's because young people like to hang out in nightclubs and the like, and it's normal to return late, but this gives me plenty of time, so I feel that I should take advantage of He Ling's departure to do a good job, so I ......"

When he said this, Gao Desheng's face was full of remorse, and he directly patted his thigh and said: "I was wrong, everyone did a good job of stepping on the point, and I even arranged a specific escape route." ”

"The time is also accurate, according to the observation of the past few days, I chose a very critical and safe time, that is, He Ling left home for half an hour. ”

"But I never expected that when I knocked on He Ling's door and was about to burglary her house, I didn't know what was wrong, and the woman suddenly returned home. ”

Gu Chen frowned, remembering that night, He Ling was persuaded to return by Ding Liang and Huang Zunlong on the road outside the villa, and he was suddenly upset.

On the day of the co-authoring, He Ling went home early, and it was also a choice made after being interrogated by the police.

If judged according to Gao Desheng's normal logic, He Ling should not have answered at this time, but she showed up instead.

Maybe it's all fate.

Gu Chen raised his head and asked, "So, He Ling found you?"

Gao Desheng nodded first, then shook his head.

"Did you find out? What does it mean to nod and shake your head?" Officer Wang also said angrily.

Gao Desheng said weakly: "I didn't find out, but when I heard He Ling go home at that time, I hid in her room and shoplifted." ”

But after hearing that she came back, I was so frightened that I quickly hid under her bed, but later, He Ling didn't go anywhere, just ran to the room. ”

She took off her shirt and ...... He lay on the bed and fell asleep. ”

After a pause, Gao Desheng said again: "But an hour has passed, and I thought to myself, I should have fallen asleep, right? After all, I dared to commit theft, and I was blocked in the room, which can only be regarded as my disadvantage." ”

"So I'm going to take the stolen items and leave quietly, so that He Ling won't find out. ”

"And what happened later?" Gu Chen asked.

"After ...... Later?" Gao Desheng blinked and recalled carefully: "Later, I was about to leave, but I stood up and looked at He Ling who had withdrawn her clothes on the bed, I ...... I couldn't help but take a few more looks. ”

"To be honest, my figure is so good, I can't help but get closer. ”

Speaking of this, Gao Desheng seemed to be still reminiscing about the beauty of that night, but when he found that the police were staring at him, Gao Desheng immediately changed his tone again:

"Comrade policeman, I had an idea at the time, but after all, I came to steal something, I didn't come to rob S, so I just took a few more looks. ”

But I didn't expect that outside the community, I didn't know which unlucky grandson drove a trailer by, and the tire suddenly burst at that time. ”

"Well, the pet dogs in the whole community, as well as the battery car, were shaken into a lot of noise, He Ling was also at that time, she was so frightened that she opened her eyes, and she directly saw me standing in front of her. ”

"You're in luck. Yuan Shasha also snorted coldly, feeling that this guy is really doing something, unlucky first place.

Gao Desheng nodded and admitted: "That's right, I'm quite unlucky, it's like stealing something, but who would have thought that the master would go home early, I have been observing for several days, and I have never said that I went home early." ”

"That's it, but when I was about to leave the room, the tire burst again, and I was directly discovered by He Ling. ”

"And then?" Officer Wang continued.

"And then...... And then?" Gao Desheng lowered his head and said with some shame: "At that time, she wanted to scream, but I messed up for a while and directly pressed her down on the bed." ”

"But I know, I'm here to steal, not to rob S, if you break the ring, you police will definitely be able to find my traces. ”

"So I just knocked her unconscious and was ready to continue scavenging for something, after all, this trip was too dangerous for me to go home empty-handed. ”

"But what I didn't expect was that this He Ling suddenly woke up when I was stealing and continued to yell. ”

"I then pulled out my knife and threatened to kill her if she dared to scream again. ”

After Gu Chen completed these records, he looked up and asked her, "Then what is He Ling's reaction?"

She ...... She agreed, she didn't dare to scream for help anymore, but I didn't feel at ease, I had to keep her in my field of vision, so I could scavenge things to feel at ease. ”

"But after all, He Ling is a big living person, and she is not easy to deal with, so I used some ropes torn from her house, took local materials, and tied her to the staircase, so that she could be within my field of vision. ”

"Wait a minute. Gu Chen suddenly interrupted Gao Desheng's speech and asked, "Were you wearing a hood at the time?"

"Yes, I was wearing a hood. Gao Desheng nodded fiercely, and said: "But I have been in contact with him a few times in the community, so I am afraid that she will recognize him, so I have never dared to take off the hood." ”

"But when I was about to leave after I had searched for what I wanted, I was afraid that she would call the police as soon as I left, so I thought about blindfolding her so that she didn't know if I had left. ”

But when I was about to blindfold He Lin with a black cloth, she thought I wanted to violate her, so she struggled violently. ”

"I didn't think too much about it at the time, I just thought about blindfolding her, sealing her mouth, and then turning off the lights and warning a few words, I guess she would be honest. ”

"But this is just my idea, it is too difficult to operate, He Ling thought I wanted to violate her, so she resisted fiercely. ”

I threatened her with a knife, but she didn't pay attention, and directly hit me on the head with her head, trying to knock me away, but this push was a push, and the force in my hand was not grasped well, and the sharp knife in my hand stabbed directly into it. ”

Speaking of this, Gao Desheng grabbed his scalp with both hands, and also regretted it: "I really didn't expect it, I didn't expect it to be like this, watching the white knife go in and the red knife out, I realized that I was going to be finished, I was frightened at the time, and quickly left the scene with the stolen things." ”

"But I don't know what happened after that, and it wasn't until tonight that I dared to come out of the RV to see what was going on at He Ling's house. ”

"I also want to know what happened to He Ling in the end, because I heard that there were dead people in that community, and I estimated that it should be He Ling. ”

"So you want to go to He Ling's community tonight to inquire about the situation?" asked Gu Chen.

Gao Desheng nodded silently: "That's right, I guess it's a big disaster, I'm afraid, I really didn't mean it, and I didn't expect this to be the case." ”

Looking up at Gu Chen, Gao Desheng said again: "So when I saw your police car on the side of the road, I was frightened, I felt that you policemen must have come to arrest me, so I ...... I'm scared. ”

"When I saw your police car turn around, I felt that I shouldn't go to He Ling's community anymore, maybe your police would be there waiting for the rabbit, so I also quickly turned around, I want to hurry back to the RV and talk about it for a few more days for the time being. ”

Looking up at everyone, Gao Desheng was also quite helpless and said: "But sometimes people are unlucky, and he is unlucky." ”

"The first time I walked out of the RV after committing the crime, I was caught by you on the road, and my fake ID was searched, why do you think I'm so unlucky. ”

"It's not that you're unlucky, it's that the French Open is being restored. Gu Chen directly took the written transcript to him in person and said, "Sign your name." ”

......

......

Early the next morning.

Criminal Investigation Group 3 of the Seremban Branch.

After last night's overnight interrogation, Lu Weiwei, Officer Wang and Yuan Shasha were exhausted, and they were listless during work hours.

On the contrary, only Gu Chen was in good spirits, and it seemed that he didn't sleep all night, which didn't matter to him at all.

Many of the three new cadet officers, although they have not seen "How Steel is Made", know very well "How Iron Man is Made".

Gu Chen is an iron man in everyone's minds.

But this kind of iron is not something that everyone can learn overnight.

I usually don't see Gu Chen exercising, and even on the basketball court in the backyard of the Furong Branch, Gu Chen is rarely seen.

But even so, Gu Chen's body was like an iron beating, not only gradually getting stronger, but also seemed to have increased a lot of muscles.

Many old comrades in the Furong Branch even secretly asked the three groups, especially Gu Chen's roommates Ding Liang and Huang Zunlong, to see if Gu Chen was secretly eating some muscle-building protein powder.

I still want to buy it according to Gu Chen's formula.

The result is predictable, and the answer, of course, is no.

Gu Chen can grow muscles even if he drinks cold water, which is very incomprehensible.

In the office of the third group, He Junchao couldn't help but ask curiously: "Gu Chen, I heard that you have solved the case last night?"

"Yes. Gu Chen nodded silently and was writing materials.

"It's pretty good, I'll sleep in one night, you've done everything?" He Junchao felt that he was useless again, so he could only say with a depressed face: "It seems that only the 'Watchman' case still needs me." ”

"I don't need it anymore. Gu Chen said.

He Junchao was stunned for a moment, then quickly turned his head and asked, "What did you say? The case of the 'Watchman' is no longer needed? What is the situation? Do you know who the Watchman is?"

"Pretty much. After Gu Chen finished writing his name on the last line of the material report, he put the pen into the pen holder, looked up and explained to He Junchao:

"Last night we went back to He Ling's house again, and from her house, we brought back the objects that we had missed before, including the various texts she had written before. ”

"I don't understand. Of course, He Junchao didn't understand Gu Chen's words, and his head shook like a rattle.

Lu Weiwei, who was sitting in the front row of Gu Chen, also said in a tone like an educational scumbag: "It means that in He Ling's room, we found a letter paper that was exactly the same as the threatening letter. ”

"In addition, we also found He Ling's previous handwritten manuscripts on some transcripts, many of which were written in regular script, the same as those in the threatening letters. ”

"Is there such a thing? She He Ling also wrote a manuscript by hand, could it be that she wrote horror?" He Junchao was also very surprised.

Officer Wang yawned and said: "Almost, this woman actually has a lot of things in her heart, she usually doesn't say it on social accounts, she records it in a diary." ”

Sitting up straight, Officer Wang said again: "Gu Chen and I found a copy of He Ling's diary last night, uh...... It's not a diary, after all, she writes about her mood in three or two days, sometimes once a week, let's count her weekly notes. ”

"That'...... What's written there?" Hearing Officer Wang's words, Officer Ding on the side was also curious.

Gu Chen said with a light smile: "What is written in it is the resentment in her heart, she hates her boyfriend Zhang Heng, she is addicted to games all day long and ignores her, and even breaks up with herself because of games." ”

Zhang Heng himself is also a person with a small personality, who likes violent and bloody games, and He Ling is also a person who likes to write dark articles. ”

"The two got together, it was indeed quite suitable, so He Ling wanted to teach Zhang Heng a good lesson, after all, it was Zhang Heng who dumped He Ling, which made He Ling very unhappy. ”

"So...... So, those threatening letters were actually written by He Ling?" asked He Junchao.

Yuan Shasha smiled and said, "That's right, these threatening letters to He Feng are really written by her." ”

Because He Ling knew that if she wanted to teach Zhang Heng a lesson, it was not her style to give it straightforwardly, so she wanted to borrow a knife to kill people, use it to threaten the newly moved neighbors, and then blame Zhang Heng and make Zhang Heng suffer a little. ”

"Since Zhang Heng's game account is 'Watchman', He Ling used this signature to forge a threatening letter, the purpose of which is to let our police take care of this Zhang Heng who wants to play dark games, so that he can have a longer memory. ”

Lu Weiwei also smiled lightly and said: "That's right, who let this Zhang Heng not want a girlfriend as long as the game, he doesn't know, when a woman decides to take revenge on a man, it is very scary, but it can't be solved by spraying the word 'scumbag' on your luxury car." ”
