The girl was so frightened that she covered her head with a sheet and covered her mouth to prevent herself from being discovered. The murderer stood in front of the bed and looked at her, holding something in his hand. The man stood still and stared at her, and after a moment she felt the man walk out of the room and close the door. ”

"The end result was that all three died that night, and their bodies were dismembered."

"The only person suspected of committing the crime is the one in the village."

"This person is suspected of committing a major crime, and the act of taking pictures proves that he knew what happened that night, and he deliberately spent the night next to that room, what did he do that night. Will it take the whole night to not be able to sleep and then have a special idea about that wall? Are the current murderers so good at mental quality, and they are getting better and better at playing. Xigui said.

"In fact, in criminal psychology, there is a characteristic of perverted homicide, that is, they enjoy the pleasure of killing and enjoy the thrill of this thrill."

"The kind of murderer will remember the crime process in his heart repeatedly, and for the psychopathic murderer, killing is an art, not just stuck between fear and fear."

Some perverted murderers abroad not only have excellent psychological quality, but also can create scenes of murder to confuse the police and have terrible investigation and counter-investigation capabilities.

Xigui said: That kind of example happened not so long ago, when we were in another criminal police team, simulating a murder scene.

"During a mission, a homicidal maniac was investigated for two months, arrested!"

"Just when our detachment leader and the criminal police were arresting the criminals, they had already passed away with their families."

Before leaving home, they usually make excuses to tell the people around them that they are traveling outside, something is wrong, and the next day a photo of the work was published on the news. It was a photograph taken from a photograph.

The police who were present at the time were defenseless against the people who came to help, and this photo should have been taken secretly by him with his mobile phone. Later, I contacted the people of the news agency, and the people did not know what corpses were here, only that this was a well-known artist in the province, so they published a photo of this work. At that time, the murderer personally went to the newspaper office to submit his article and provided his own proof, and he claimed to the people in the society that this was his best work and could make a sensation in the world! "The photo news of the day went viral immediately!

The suspect's fame rose and he became the focus of attention overnight, and the photo of the *corpse became everyone's topic. Media across the country are planning to cover the incident, and reporters are filming reports every day in the place where the crime occurred, and the people next to them have been interviewed by the media many times. At the press conference, many media set up cameras and waited.

At that time, the chief of public security, the captain, and our officer Wu of Hu discussed together. The director of the public security bureau believes that the power of the media should be used to issue large-scale wanted notices and disseminate information on the identity of murderers nationwide to implement public wanted notices. Officer Wu's point of view is that before the murderer is caught, it is not appropriate to disclose too much, and the negative impact is too great.

After learning part of the news about the murderer, the detachment leader was familiar with the surrounding relationships, and he said that he was willing to lead an arrest team to arrest the murderer and investigate his whereabouts, and there was great hope that he could successfully capture or trap him. The arrest plan was discussed. The special case team did not say a word. When the police consulted the special case team for their opinion, the police captain said decisively: That person may not be the direct murderer. It was a bolt from the blue! The criminal police team and the local police spent so much effort to find a murderer, but they were easily denied by the special case team.

"At that time, when the clue felt like it was going to be broken, we were all about to collapse, because we had not rested for a long time for this case." Xigui said.

The then chief of public security asked: If he is not the direct murderer, then who is the real murderer? ”

This thing has made everyone's heads big.

Later, we started to simulate the restoration of the case.

Our police officer Wu said: This murderer is a criminal suspect, all the clues point to him, which reporter thinks he is the murderer who killed others, if he is an innocent witness, why did he abscond? They also deceived journalists by publishing photos with bodies. The murderer took the body inside the walls for a work of art? "At that time, the detachment leader called other people to help, and it was a fortuitous factor. If he is a murderer.

"Why did you take a photo secretly and blatantly publish it in the news media?" Want to be famous.

The captain looked through the transcript of the visit and said: I don't know the specific reason.

Professor Liang also looked through the case file and said, understood, let's go, let's go to the press conference. Director: I know who the killer is. Okay, you go to the press conference, we don't participate, you are responsible for what happens! At the press conference, the criminal police team gave everyone a wonderful criminal investigation simulation case lesson. ”

The staff then used a projector to play all the pictures of the physical evidence found by the police, and gave the most detailed explanation, and then recorded them.

”

"A geologist who doesn't need to see a rock with his or her own eyes can infer from a grain of sand that it could exist. Using just one phenomenon, the average distance from the Moon to the Earth can be calculated.

”

"A lot of things are presented in the form of reasoning. Although the conclusion of reasoning is not necessarily reliable, it can quickly discover the truth, but it is an important way to discover the truth, and it can be accepted by everyone, right? ”

"In criminal investigations, reasoning is an indispensable tool. For example, this on-site restoration.

”

"Forensic reasoning is based on the analysis of the scene and clues, and then a guess is made.

”

"There is also a foreign bombing case that is one of the most famous cases of reasoning in the world, where criminal psychologists analyze and deduce the murderer's gender, age, place of residence and other information from just a letter from the murderer. Finally assist the police to catch the suspect! "We showed the belongings of the deceased to reporters, and the reporters took pictures, and the director said can you tell me, who knows what this is for?" A reporter replied: He may be short of money, right? Pawn it! ”

Another reporter said: It may also be given as a gift.

The director said: No problem, both statements may exist, we need to rule out one of them, first of all, I can be sure that his family is not short of money! ”

"The director continued: Different foods have different digestion times, and there is only one possibility left, killing at night, and the time of eating at night in the summer plus the time after that, is the time of death."

"What are you taking that thing for? The reporter asked again. ”

"The deceased will not choose to be at night, and there is no need, there is only one possibility, this ring is given as a gift, and it is worth a lot!" The director speculated. "In the process of proving the scene, or in the latter more complex reasoning process, the director takes the conclusion of the previous reasoning as the premise of the latter reasoning, considers whether the conditions are met, and deduces the case step by step until the necessary conclusion reasoning is analyzed, so that it is easier to investigate and collude the case.

”

"Later turns out that the director's reasoning was completely correct, that the gold ring was a gift from the deceased to a relative." That relative was the nephew of the deceased. ”

"In order to surprise his nephew, the deceased took a gift and made something for his nephew. Later, the police found him, and he came to confess to the police that they had such a conversation. ”
