Jiang Hao laid out a series of criminal evidence, each piece of evidence was enough to corroborate the evidence he presented, the police in charge of criminal investigation had already been shocked by Jiang Hao's wit, and he couldn't hide his excitement and stood up, and took the initiative to ask Lin Ke, the director, to say: "Let me go directly to arrest people, and then interrogate them." ”

"Your task today is to listen to the class, learn the skills of solving the case, and naturally someone will go over to arrest him, so you can listen to the lecture with peace of mind, and when the person is arrested and the interrogation results are available, I will inform you." Link said to the detectives who were about to get out.

It's not the first time that Link has cooperated with Jiang Hao, he has already informed some people to prepare for arrest, after Jiang Hao announced the results, he didn't wait for Jiang Hao to give a reasonable explanation to the suspect, because he believed in Jiang Hao's judgment, and he had already sent a message to people to arrest people, believing that it wouldn't be long before the murderer would be arrested and interrogated, and now he only needs to wait patiently for the results of the interrogation.

"Okay."

The criminal policeman who was about to leave, did not expect that Link had already made preparations, and he himself was unwilling to leave at this time, after all, it was rare to have the opportunity to learn the skills of solving the case, so he naturally had to cherish it, and reached out and took out the notebook he was carrying, recording what Jiang Hao had just explained.

There are not a few people who have the same actions as the criminal police, and they all seriously bury their heads in making notes, so that they can be taken out and reviewed in the future.

"Everyone is listening attentively today, I have asked people to record from the beginning, and I will pass a copy to you when I go back, and then discuss it in a meeting, don't take notes, and listen carefully."

Link said in a commanding tone to the officers who were buried in the records.

Link could see that the police officers who were immersed in the record were all summarizing from the heart, which made him very pleased, and it was not in vain that I had worked hard!

"Let's do the analysis of the second case."

Jiang Hao saw the policemen in the audience, one by one, straightened up, sat meticulously, was ready to listen, and continued to speak: "The second case, what I want to hand over to you is to solve the case from a psychological point of view.

The psychology of the offender is complex, but if you look closely, you can find some similarities.

For example, in the second case, this case is also a homicide case, and it is also a burglary and homicidal case.

Analyzing clues and residual traces, comparing fingerprints have no gains, our Huaxia fingerprint system is still in the establishment stage, if you keep looking for it endlessly, you want to gain something, unless it is the next time the criminals commit a crime, they leave fingerprints as an assault port.

But if criminals get away with it for a minute, they will threaten the personal safety of others, but they are suffering from no clues, so we might as well imagine the psychology of criminals at this time.

As a criminal, even if it is a murderous criminal, after the murder, he will have fear, fear of whether he will leave clues, fear of the progress of the case, and whether the process of committing the crime will be discovered .......

According to criminal psychology research, criminals will mostly appear near the scene in the early stage after committing a crime, because the progress of the case can be quickly obtained near the scene, so as to decide whether to stay or choose to escape.

I looked at the photos taken by the police at the scene, compared them carefully, and finally identified a man as a criminal. ”

Jiang Hao handed the photo to Fang Meng for enlargement.

The content shown in the photo is a group of people watching the excitement, and the reason why the crowd was photographed is naturally not that the criminal investigation department did nothing to take a blind picture, there is a bloodstain at the bottom of the photo, and when the bloodstain was taken, the crowd of good things was inadvertently encircled.

Jiang Hao's hand at the moment was pointing at a man in a black jacket, a scruffy beard, and a thin face in the photo, the man leaned his neck, like a crowd of onlookers, and was very curious about the policemen who were collecting clues.

"Why are you going to lock him up?"

Someone in the audience questioned that there were about twenty or thirty heads in the photo, and they couldn't figure out why Jiang Hao would lock the man in the black jacket.

"Observe."

Jiang Hao succinctly spit out two words, pointed to most of the people in the photo and said: "The deceased was found in the morning, and it was another Sunday, and people who had been busy for a week, and they were probably sleeping in bed at this point in time, and the sudden sound of police cars naturally attracted people."

But all of you are dressed, most of them are wearing loose home clothes, and some are even wearing pajamas, which shows that they are all from their own homes.

Excuse me, what about the prisoner stealing in his pajamas? The only exception in the photo is the black armor man, you can see that he is dressed very neatly, and that alone can select him as the perpetrator to check the scene of the incident.

But this alone is not enough to judge, take a closer look at his shoes, the surface of his shoes is stained with yellow paint, which is exactly the same as the paint on the wall outside the slain's house, the whole community can only be the outside of the slain's house The wall is yellow, and the inspection of the deceased's home found that someone did enter through the window, which further shows that he has a big problem.

Looking at his hand movements carefully, his hands were crossed fiercely, his eyes were anxious, and there were obvious sweat stains on his head, which proved that he was very nervous at the moment, which confirmed the sentence, being a thief has a weak heart.

Moreover, he is definitely not a resident of this high-end community, you look carefully at the watch he wears on his wrist, it is obviously a cottage stall, the label of the shoes is very similar to the brand label, but it is a pity that there is one more, and then compare the accessories of the people around him, his dress is definitely shabby.

A person dressed in ordinary clothes, why would he appear in a high-end community for no reason? Isn't that something to think about? ”

Jiang Hao is like a master of analysis who is proficient in techniques, leading everyone to put aside the mystery step by step, starting from the details, and reaching the final mystery of solving the case.

"It's incredible."

The policemen below changed their faces one by one, staring at the enlarged photo like wood, one by one as if they were stupid, after Jiang Hao's reminder, they felt more and more that the man in the black jacket in the photo had great suspicions, and they admired Jiang Hao's observation very much, and secretly sighed, why didn't they pay attention to the crowd after they also saw the photo in the first place?

However, everyone also believes that even if they really notice the crowd, they will not be too suspicious, because they can't imagine that the thief who killed someone will come back from a new one to check, which is too unreasonable, but it is very in line with the heart of the criminal.

But the point is, no one would have thought that this could also solve the case!

"It's incredible, it doesn't mean that he doesn't exist, solving the case is to be bold and carefully verified, so that we can remove the fog and reveal the truth."

Jiang Hao said calmly.

"Hmm."

The policemen in the audience nodded approvingly, Jiang Hao's summary was very short, but every sentence was very incisive, and everyone took Jiang Hao's words firmly in their hearts.

I am also looking forward to catching the person in the photo as soon as possible to see if he is a murderer, in fact, to be honest, everyone has already agreed with Jiang Hao's guess in their hearts, so much evidence is placed in front of them one by one, no one will have doubts.

"Since we talked about removing the false and leaving the truth, I will analyze the third case for you, that is, from the interrogation confession, find useful clues and ignored parts."

Jiang Hao changed his words and set his eyes on the third file: "The interrogation data of this information shows that the death obtained by the deceased after the autopsy was a recurrence of allergy-induced heart disease.

The reason why the case has been kept is because the mother of the deceased suspected that her daughter was murdered by the woman married by her ex-husband, but after the police interrogation, the results showed that when the deceased died, the deceased's stepmother had alibi evidence, so the case has been stranded and cannot be solved.

I have to say that a woman's intuition is really accurate, the deceased was indeed killed by her stepmother, and the police couldn't break it, just because her stepmother was more clever. ”

"What does it look like in the testimony?"

The police officers who were in charge of handling this case suddenly came to their senses, and they had a deep memory of this case, because the deceased's mother had been checking that the woman had been killed by her stepmother, and had come to the police station several times to make trouble for this reason, resulting in no way to close the case.

If Jiang Hao really found out the murderer, he would really be able to make the deceased's mother not come to make trouble, and give the deceased justice.

The testimony shows that the deceased's stepmother confessed that he went to buy perfume, and there were also invoices from the other party and the clerk of the perfume shop as evidence to prove her innocence.

It's just that the vicious stepmother deliberately omitted a passage, that is, the perfume he purchased was to be ordered in advance, and when she made a reservation in advance, she would pass by a flower shop, and this flower shop sold a wide variety of flowers, and the deceased's favorite flowers were ordered in the store.

I believe that he must have gone to order the perfume and put the colorless, odorless, volatile medicine that had been prepared for the perfume into the flower that her daughter liked.

Someone who buys a flower with a drug will not have any reaction because they are not allergic to certain substances.

But once the flower is asked by the daughter who bought the flower on time, there will be a stimulating reaction, and once the rescue is not timely, the consequence is death!

And drugs with volatile effects, once volatilized, disappear without a trace, and the police can't find them even if they check it.

It is only necessary to find evidence that he has purchased stimulant drugs to form a chain of evidence to prove the facts of his crime. ”

Jiang Hao's voice was cold. The human heart is the most sinister and unpredictable, in order to get what they want and satisfy their own desires, many people do not hesitate to plunder the lives of others at the expense of others, resulting in the abounding of people who are careless, sad, lamentable, since they have met, let themselves give the dead a justice!

"I see."

The policemen who participated in the case at the beginning showed complicated expressions, and they didn't expect that the deceased was mutilated by her stepmother like this, and the means were really clever enough, secretly sighing, meeting such a ruthless stepmother, it was really eight lifetimes of blood mold.
