Profiler 2: Criminal Investigation Brigade

The paper media has long since declined. Even the most powerful "Shencheng Evening News" in the local area, no one has taken it now. Even the old man reads it on his mobile phone when he is playing chess.What's more, it was such a professional newspaper of the public security system, and it was this, and his eyes, that caught Jiao Yang's attention.

Jiao Yang glanced over, motioning for Hou Xiyong to follow.

Hou Xiyong understood, and the two pretended to be chatting, and followed the man to a nearby library.

Jiao Yang asked Hou Xiyong to stare at the man, while he came to the front desk, showed his ID, and asked to check the man's past book borrowing records.

The list of books that the man borrowed looked a bit professional, and they were all monographs on criminal psychology, such as "Criminal Psychology" waiting for the United States, and "Portrait of Criminal Minds" by Tevey: Introduction to Behavioral Evidence Analysis", Liao Youlu's "Crime Anatomy-Theory and Practice", and several famous criminal investigation novels "Psychological Crime", "Forensic Qin Ming", etc.

In view of the man's attire and book list, Jiao Yang felt that this man was a bit suspicious, so he had to make some inquiries.Jiao Yang deliberately walked up to the man, and glanced at the sticky note in the man's hand out of the corner of his eye.Unexpectedly, he saw this sentence: criminals have erratic eyes, and they must keep their eyes focused.

This is not a celebrity walking on the stage, why should ordinary people always pay attention to their eyes, and make a difference from criminals?Unless, he is...

Moreover, as a criminal policeman who studies criminal psychology, Jiao Yang knows very well that many criminals will return to the scene after committing a crime, and even go back to check more than once.Especially the series of cases of perverted killers.Either they came to inquire about the news and see if the police found any evidence at the scene.There are also some who are extremely psychopathic, and they come to appreciate the distraught and inexplicable grief and anger of the victim's family.

And the place where they came out just now is the community where the first crime happened.Jiao Yang felt a policeman in his heart, and walked directly to the legal books display area, flashed his ID and said, "I am a policeman, sir, show me your ID card."

"I... I didn't break the law, why do you check me..."

The man said, threw the book in his hand, turned his head and ran away.

But Jiao Yang had been prepared for a long time. With a sudden leap forward, he clasped the man's wrist, and when his knee moved forward, he resisted the bend of the man's leg.

As soon as the man's legs softened, he knelt on the ground, but he still struggled desperately. He reached out and grabbed the bookshelf next to him, pulled hard, and with a crash, the milky white bookshelf turned over on its side.

Jiao Yang was afraid of hurting others, so he quickly supported the tall bookshelf with his sharp eyes and hands.

Taking advantage of this moment, the man stumbled up and continued running.

Hou Xiyong realized something was wrong, so he caught up and kicked the man down.

The man rolled on the ground and yelled desperately, "He beat someone, the police killed him!"

Jiao Yang lifted the bookshelf and handed it over to the rushing security guard. He took off the handcuffs from his belt and handcuffed the man. He asked Yu Xiaoguang to drive the police car over and took the man back to the police station.

The man struggled all the way, "Why do you arrest me? I didn't break the law, you have no evidence, why arrest me?!"

Not breaking the law and having no evidence are not the same concept.These words strengthened Jiao Yang's confidence even more.

Jiao Yang immediately asked the man, "What's your name, what do you do, and what are you doing at the crime scene?"

The man said domineeringly: "I'm just passing by to see the excitement. Am I breaking the law when I go out on the street? Do you care what I do?!"

"It's quite horizontal!"

Hou Xiyong rolled up his sleeves, slapped the table on the table and said: "I haven't seen it for a while, the second one who plays a bachelor in the police station, and the previous boss who was so active here, now seeing me, his calf is still twisting." What! Don’t say yes, okay, you don’t need to spit ivory out of your dog’s mouth, I don’t believe it, I can’t cure you bastard!"

Yu Xiaoguang knew that Jiao Yang didn't like this, so he grabbed Hou Xiyong and said to the man: "You don't even dare to say your name, do you have a ghost in your heart? Are you a fugitive with a criminal case? You must know that now that technology is advanced, we only need to check you If you don’t have your identity information, you know everything, and it’s useless for you to hide it.”

The man muttered, "I have the right to remain silent, and I won't say anything until my lawyer comes!"

"Fucking lawyer, can you write these two characters?!"

Is this fucking TV series watched too much?Hou Xiyong sneered and said, "Come on, boy, just call me, I'll call you a lawyer right away!"

"I, I know Feng Xi...just that Lawyer Feng..."

The man couldn't speak out loud.

Feng Xining is a relatively well-known local public interest lawyer in Shanghai. He has appeared on many TV stations' legal columns, and has dealt with the police station, so he is familiar with them.Yu Xiaoguang thought, it's just that people don't know you...

"Cao Nima, you are kidding me! I will give you a long memory!"

Hou Xiyong stood up, looked at Jiao Yang and said, "Boss, do a search?"

The current situation is grim. If this person is really the case, he must not be let out to continue killing people.If not, evidence must be found as soon as possible.Jiao Yang thought for a while, then nodded in acquiescence.

Hou Xiyong called Yu Xiaoguang, regardless of the man's screaming and struggling, he carried him out, dragged him all the way to the toilet, searched him, and found that the man did not bring his ID card, only a few dozen dollars and a smart phone of an off-brand .

However, Hou Xiyong immediately discovered that this person's browsing history was a bit infiltrating.How many pesticides can kill a person shows that the drug can completely corrode the corpse, what kind of knife is suitable for dismembering the corpse, what can detect DNA, and so on.

However, the man's mobile phone number was inquired through the operator, but it was found that the owner of the phone was a woman, obviously not the person's ID card.

Hou Xiyong printed out the man's browsing history and explained the situation with Jiao Yang.

Jiao Yang frowned, and said decisively: "Notify the first crime scene to be located in the community, and nearby neighboring communities, and ask all the foremen of the decoration company hired by the owner who is currently renovating to come and identify him!"

A few foremen rushed over one after another, and there really was someone who was wearing the outfit that Jiao Yang estimated before, wearing a straw hat, a rubber jacket, and rubber shoes on his feet.

"Hey, isn't this Xiao Wan! What happened to him? I said why he disappeared, so he came to the police station!"

One of the foremen recognized him, and the police learned that the man's name was Wan Haichao, XX, 29 years old this year, and he mainly worked on construction sites, and occasionally went to do small jobs in decoration companies.

The police force quickly consulted the relevant local identity information, and felt that it did not match the man's appearance.Zhou Ying thought it was an accent, and tried a few words with similar pronunciations, but couldn't find them.

Later Jiao Yang said: "The 29 they said should be a false age."

After Zhou Ying re-inquired, she checked her identity information and found that Wan Haichao had no criminal record and was not a wanted person on the Internet.

Jiao Yang asked Hou Xiyong and others to confirm with the decoration company in the previous community whether this person had ever worked there.Then notify the victim's family, organize the identification process, and go to the police station for identification to see if this man has ever had a dispute with the victim.

Who knows, not to mention Xia Ke, Meng Zhaowei, Wei Peng and others, even the victim's parents, relatives and friends who came over after hearing the news all said that they had never seen Wan Haichao, and they didn't know Wan Haichao at all.

Wan Haichao seemed to be proud all of a sudden, and shouted: "Why do you arrest me for no reason? You are abusing your power. I can apply for compensation from the state!"

Jiao Yang felt that Wan Haichao's words and deeds were consistent with Lu Yuanli's. He thought he knew a lot about criminal investigation and liked to pretend to be smart, so he couldn't let this person go easily.

As soon as he had an idea, he asked Yu Xiaoguang to come up with a formula.

Yu Xiaoguang was stunned for a moment, then understood, and gestured for Hou Xiyong to go out.Yu Xiaoguang took out a cigarette case, took out a cigarette and handed it to Wan Haichao, saying, "Come on brother, take a cigarette, it was all a misunderstanding just now, I'm sorry. Our leader is just a little suspicious, there is no way, the first-level official Crushing people to death. We have to do whatever the leader tells us to do! This is none of your business, so don’t take it to heart.”

Wan Haichao took the cigarette but didn't smoke it. He held it in his hand and said, "Then can you let me go?"

Yu Xiaoguang took a cup of hot water from a paper cup, put it in front of him and said, "Let's get cold, drink some water. I'll ask the leader later, it's nothing, I'll let you go after a formality."

After staying at the police station all day, Wan Haichao was thirsty and hungry, so he hesitated to pick up the water glass and took a big sip.

Hou Xiyong suddenly appeared at the door, looked at the two suspiciously and said, "What are you talking about? Team Jiao said that someone is coming again, let me take him there to recognize him!"

Hou Xiyong took the man away, and Yu Xiaoguang took the paper cup Wan Haichao had used and hurriedly sent it to the Technical Detective.

Now, what else could they do?Jiao Yang slapped his head, called the foreman who recognized Wan Haichao, and said, "Do you know where his home is?"

The foreman was stunned and said: "Oh, I really don't know about this... It's okay, our bricklayer's Xiaobao must know, please wait a little bit, leader!"

The foreman asked Xiao Bao, who was in charge of finding the bricklayer, the person who introduced Wan Haichao to work.The man asked a few more workers to inquire separately, and finally found out the detailed address of Wan Haichao's home.

Jiao Yang led the team and hurried to Wan Haichao's residence.

A few people went in to have a look, and Hou Xiyong laughed, "Isn't this another thief's meeting!"

In the narrow one room and one corridor, the most eye-catching thing in the corridor is the administrative map of Shencheng City, the traffic planning map of the bus and subway, and five orientation maps drawn by individuals.

It is full of marks with red pens, such as time, place, person, purpose, route, etc., and beside it are "underpass", "negative second-floor garage", "avoid elevator monitoring" and so on.

On the first three pictures, they were marked with thick marker pens, and the words "death to those who do not obey women's morals", "death to those who quarrel with others", and "death to those who are rich and unkind" were pasted on colorful stickers. Among them, the word "rich" was also wrongly spelled.

The next two sketches did not have a check mark, but a yellow question mark, with the words "death to those who have adulterous affairs" and "death to those who beat and scold the elderly".

Jiao Yang glanced at it and recognized it. Those three rough and scribbled maps were the three crime scenes.

At this point, it can basically be concluded that this is the residence of the murderer of the three burglary murder cases, and the rest is just a question of whether it is Wan Haichao.

Wan Haichao has only one room here, with only a folding bed and a small square table, and cement sand buckets, trowel knives, hemp rope and other tools are thrown on the ground in the corner.

Under the mattress, the police found a handful of guns and an old-fashioned smartphone, which contained photos of the three deceased, and the blood of the first two had not even clotted.

When Jiao Yang came back, Wei Fenghao happily ran over and said, "Yes, yes! Team Jiao, Wan Haichao's DNA matches the stomach contents you found at the scene of the crime for the first time. people!"

At this time, everyone breathed a sigh of relief, and the serial murder case was finally solved.

Jiao Yang was not happy, but just handed over the new evidence found at the scene to Wei Fenghao and said, "Check the dagger and the phone, if you can find fingerprints, is it Wan Haichao's?"
