twin detective

"Is it inappropriate to think that these two cases are related just because the suspect may be a doctor?" Ning Zhi just stared at the mind map put together on the whiteboard, and felt a toothache.

He retracted his gaze, looked towards the other side of the desk, and couldn't help reaching out and tapping on the whiteboard.

The mind maps listed above come from two cases respectively. The murder case of Lin Feifei is on the left, and the case of the Drama Theater is naturally on the right.In the middle of the two maps, there are three big characters of "scalpel" written brightly, representing the connection between the two cases.

At this time, Ning Zhi took the pen again and added a circle above the three words, "The result of everyone's discussion is that the tools used to commit crimes are related, right?"

"Yes, we have discussed this before, and the source of the crime tool in the last case has been identified. It was stolen from a small dentist's clinic. According to the normal situation, referring to the management regulations on medical devices, the crime tool this time should be It is also strictly controlled, and it is a device that is not available in community hospitals or small clinics."

"This is scary, it's something that can cut bones." As soon as Ning Yuan's voice fell, Fang Ye answered, and then went to stab Lin Zang's arm next to him, "What about you, what do you think about this case?" look?"

"I don't know much about the last case either." Lin Zang looked a little dull when he looked away from the laughing and joking appearance of Fang Ye on weekdays.

There was silence in the office.

Fang Ye looked around and saw that neither of them had any intention of speaking, so he could only hide his embarrassment with a smile on his face, "We just talk in private. If you think there is something wrong, just say it directly as usual. alright."

They were sitting like a "one-on-three". Ning Yuan could clearly see the expression on Lin Zang's face just by turning his head. He clearly wanted to slap Fang Ye's head, but he had no choice but to do so. Look, it's a bit embarrassing.

The eyes of the two met for a brief moment, Ning Yuan hurriedly avoided, and then looked at his brother, obviously asking for help.

"Lin Zang didn't do this in the first place, and it's a bit difficult for us to force him to come here." Ning Zhi got out of the situation in time, and then re-discussed the topic to his younger brother, "It's better to keep talking from a distance."

"First of all, as we have already discussed, although the two types of murder weapons have the same commonality as a scalpel, their nature is completely different. One comes from a small clinic with loose management, and the other may come from a regular large hospital. .Secondly, in the previous case, the tools were left at the scene, but this time, the murder weapons were taken away. From their sources, can we make such a judgment that the first tool was later used by the murderer? It is said that there is no use value, but there is a second one."

"Is it possible for the suspect to commit a second crime with it? Or is it necessary for him to put the crime tool back after committing the crime in order not to be discovered?"

Ning Zhi continued to speculate, but his heart was filled with great waves. The previous guess scared him too.

But Ning Yuan quickly comforted him, "It's not necessarily what I guessed. Maybe the suspect in the previous case didn't take away the tools of the crime. It wasn't out of his own will. The possibility of a third person has appeared."

"Then, apart from the fact that they are both scalpels, there is no connection between the two cases." Ning Zhi took his younger brother's words and subconsciously looked at Lin Zang's face.

After receiving no response, he turned back to the topic, "If the murderer committed serial crimes, then he should maintain a fixed criminal habit and thinking, not what he is doing now."

"If we treat all these crime methods as the same, there is no doubt." Ning Zhi said, forcibly drawing "fatal wounds in the heart" and "fatal wounds in the neck" as well as the tools of crime and the size of footprints. an equal sign.

But he quickly turned the topic around, "Let's just think about it from the perspective of the victim. Think about the relationship between Lin Feifei and Mr. Wang? As long as it is necessary, it involves criminal psychology. When inferring, we cannot infer in the most ordinary way."

"From a general point of view, when a murderer chooses to harm a person, there is usually some kind of contradiction with him, but this situation is different. They often do not have a clear motive, but choose someone with certain characteristics to commit suicide. Harm, as long as this characteristic is attracted to him. For example, a certain smell, the style of the dress, the specific personality of the victim, social status, activity area, even the color of the hair, whether the body is deformed, etc. "

Ning Zhi took what he had just learned and sold it now, which stunned Fang Ye and blinked his eyes, and finally he was so anxious that he could only squeeze out a sentence like this, "Those who have commonalities are all scumbags." .”

His voice was not low, and it immediately attracted everyone's attention.Seeing that Fang Ye couldn't hide, he simply crackled and said.

"Although the case of Mr. Wang's murder of his wife and fraudulent insurance was not finalized, it was leaked by the media. At that time, there were many people who paid attention to this matter. Basically, anyone who was on Weibo saw it. Even relatives and friends around him He was also interviewed and harassed, and all kinds of things were exposed. What happened to murdering his wife to cheat insurance, domestic violence and abuse, even those he had never done, were detained a lot, and he was accused of cheating in marriage and so on. .”

"As for Lin Feifei, not to mention, besides Uncle Li, it also involved your old case at that time. Both of them are murderers, both are men, and they are both scumbags. Perhaps the murderer saw these commonalities and decided to Choose them as targets for harm."

"According to you, the murderer has a sense of justice?" Lin Zang finally couldn't help but subconsciously exchanged words with Fang Ye, and almost couldn't help laughing out loud when talking.

Does the murderer have a sense of justice?

This sentence sounds weird, but it seems that a suitable inference can be made from this perspective.Ning Zhi added this item to the description of the suspect, and suddenly a flash of inspiration flashed in his mind, feeling that it was connected to something.

"The suspect in the second case was wearing a cleaner's overalls. Does that mean that?"

"Is there a sense of ritual?"

Although Ning Yuan was a little confused, he could still roughly guess what his brother was thinking.

Basically, most types of work have their own work clothes. First, for cleanliness and safety, and second, because of long-term use, clothes of a certain color and style have basically become a symbol of an industry.Not only can people who can be seen see their identity at a glance, but even if they wear it themselves, they can also feel the responsibility entrusted by the industry.If we talk about the performance industry, it may be that appropriate clothing and styling can make actors enter the show.

"The cleaner's responsibility is to clean up the rubbish and keep the environment tidy... so did he sweep those two as if they were rubbish?"

Fang Ye then made a hypothesis, and his expression was a bit indescribable for a while.He couldn't help covering his head again, "This kind of case involving a perverted killer is more difficult. The reason why a pervert is called a pervert is because it can't be deduced with common sense. It's hard for us to guess here and there. Find out what the other party is thinking."

"The biggest difference between the two cases before and after is the redundant behavior and marking behavior in the latter case."

"In this case, the murderer's slaps and neck chokes can still be considered as humiliation to gain an advantage. But apart from these actions, he cut off the palm of the deceased and took it away, but just threw it into the nearby garbage Inside the barrel. He also wrote a net word with blood on the side of his face, which is an act similar to signing or making a serial number. There is also a ring on the right palm. This is usually a valuable item, but the murderer Also did not take away."

"I will make an assumption based on the results first. If the right hand represents violence and authority, then the murderer cut off his palm, which should be a warning to his domestic violence and abuse. The victim put the ring on the little finger of his right hand, It means welcoming singles, so for the murderer, this may be a betrayal of marriage. As for the net word, it may correspond to his identity as a fish that slipped through the net."

"Does it mean that the Skynet is comprehensive and not leaking?" Fang Ye rarely heard Ning Zhi's explanation of criminal psychology like this, so he answered the question after feeling novel.

"Don't you think that traditional reasoning is prudent enough, and criminal psychology is mysterious?"

Lin Zang had been sitting in a muffled voice, and the silence was a little too much, but at this moment he suddenly spoke out to tease.

Ning Zhi seldom had sex with Lin Zang during this time, and felt novelty for a while, but he could only smile and admit defeat, "Actually, we also use psychological knowledge when analyzing motivations, but it's just that we don't systematically Just used it."

"So what's the result?" Lin Zang asked again.

"The result is that this knowledge is too profound. If you guess wrong, you may go in the wrong direction. I have always thought this way before, and I find it very difficult to empathize with the suspect."

"However, after a preliminary understanding recently, I realized that this discipline is actually based on traditional reasoning. Inferences can only be made after a sufficient understanding of the circumstances of the case and the circumstances of both parties. And no matter what type of The suspect, he is inexperienced at the beginning, even if he imitates the crime, there are still shortcomings, seeing and doing have always been two different things."

"Only after he has done several cases, will he form a fixed criminal habit and form a series of cases. Therefore, if we want to judge the case from the perspective of criminal psychology, it means that we need enough samples to be able to identify suspects. People have a basic profile."

"Wait for him to kill someone?" Fang Ye understood what Ning Zhi said, and because his neck retracted too late, he was glared at him fiercely.

"This is just the general direction of this subject. It may not be applicable to our case. These are just our own guesses."

Seeing that the atmosphere was not right, Ning Yuan silently expressed his condolences in his heart, and then quickly changed the subject.

"Well, until now, we have not listed the two cases as serial cases, and there is no absolute commonality between them."

Ning Zhi answered, and went to look at the whiteboard again.

"You still feel that the case of Lin Feifei is related to the old case ten years ago, and the one in the theater is just an independent special case, right?"

Suddenly, Lin Zang made this point clear.

Ning Zhi stared at the whiteboard for a few seconds before realizing what he was talking about.

He turned his head and found that Lin Zang was still looking at him with a smile.

But that smile seemed to be unable to reach his eyes no matter what.
