On a hot summer afternoon, the city is like a giant steamer, and people can't breathe.

At the end of the run-down alley is a lush sycamore tree, where people like to cool off.

A few old men playing poker were playing, and suddenly an old man looked in the direction of Wutong and said in wonder: "Why do you feel a smell around here?" ”

"I guess there is a sewer pipe next to it! Lao Li, it's time for you to get out. ”

Lao Li didn't think much about it and continued to play cards. The old lady next to her seemed to smell the smell, and muttered impatiently with her nose: "It's really lacking in morality, it's so hot and sky-breaking, what kind of sewer is it!" ”

At this time, the people in the nearby shade smelled the smell one after another, and they were all a little irritable.

"Why don't I ask the property, and I won't let people stay?"

A middle-aged man took out his mobile phone and reported to the property, and a few minutes later, the property reported that there was no notice or record of sewer repairs.

Everyone began to wonder, where did this unpleasant smell of rot come from?

"It's the smell of corpses! This year's sycamores are growing unusually luxuriantly! ”

A girl in her twenties stood in front of a plane tree and said with a strange smile on her face.

"Girl, don't talk nonsense, there are limits to joking."

Some old people complained about the girl's remarks, and the girl was not angry, and even said meaningfully: "Maybe it's under the tree!" After all, this one has a strong taste! ”

After the girl finished speaking, everyone who was sitting by the tree just now left the tree one after another, but most people still thought that this girl who had not done anything more was playing a prank.

"If you don't believe it, call the police and dig it out to see, it's okay to take a look, it's early! It won't be too late in a few days. ”

After saying that, the girl turned around and left, leaving everyone with a youthful and energetic back.

After the girl left, someone in the crowd called the police, and when the police arrived at the scene, the sycamore tree was cordoned.

A huge woven bag was dug out from under the tree by the police, and in an instant an unpleasant stench filled the air.

Guan Li frowned and looked at the lumpy object in the woven bag, and bit his back molars irritably.

"Guan team, according to nearby residents, it was a little girl who said that there was a body under the tree, so they called the police."

You Jie took the record book in his hand and said truthfully to Guan Li.

"What about the man?"

The person who called the police said that she had said these words and left.

Guan Li waved his hand to let Youjie continue to investigate, looking at the huge sun, he became even more irritable.

After the current investigation, Guan Li led the team to leave the Baifeng community, and before leaving, Guan Li retrieved the surveillance video near the plane tree.

Back in the team, Guan Li locked himself in the office and watched the surveillance video over and over again.

The murderer who buried the body and killed him didn't see it, but he could see it clearly when the residents said about the girl today.

"How is she?"

Guan Li muttered and took out a file from the filing cabinet next to him.

The old kraft paper is slightly yellowed, apparently dusty for a long time.

The file is dated five years ago, when a couple died mysteriously while driving, leaving behind only a daughter who was in junior high school.

Looking at the photos of the girl in the file, and then looking at the surveillance video, Guan Li silently closed his eyes.

In the class of criminal psychology of the Department of Psychology of North University of China, the old professor is explaining how to judge the mental activity of a criminal by the wounds of a corpse.

Zhao Yuean sat in front of the window, a blank piece of paper spread out on the table, a pencil in his hand, and his eyes wandered out of the window.

"If the body presents severe injuries, such as multiple fatal injuries, or the dismemberment of a limb, it proves that there is a great deal of hatred between the perpetrator and the deceased, and most of this hatred comes from acquaintances, and there is likely to be a circle of friends between the two."

The old professor talked eloquently, and Zhao Yuean suddenly said: "Then if the other party is killed and the corpse is broken, and the corpse is buried in a place with a large flow of people, what is the psychology?" ”

As soon as the old professor heard Zhao Yue'an speak, his temples began to hurt.

Zhao Yue'an is a student that all the teachers in the Department of Psychology love and hate, as long as she asks questions, it is definitely tricky and complicated questions, and sometimes it is difficult for psychologists to answer.

But it is this kind of student who has the talent for psychology, and it is also the focus of the department.

"There are many possibilities for this situation, the murder and mutilation of the corpse must be with the hatred of the deceased, and burying it in a crowded place is often related to the distorted psychology of the perpetrator, who wants to get attention and is afraid of being discovered.

Or if the offender is an antisocial personality and enjoys the pleasure of provoking the public, etc., this situation needs to be analyzed on a case-by-case basis. ”

The old professor explained everything in the way, thinking that he gave a reasonable answer. You can always stop this little ancestor, right?

Who would have thought that Zhao Yuean suddenly raised his head and said, "Then what if the murderer and the broken corpse are two people?" Is it to cover up the killer, or is it to expose the killer? What is the mental activity of the two? ”

The old professor almost spurted out a mouthful of blood, and originally talked about a case today to analyze the trajectory of criminal psychological activities, but he was led by Zhao Yuean to think through half of the class.

He was about to have a seizure when there was a sudden knock on the classroom door.

The head of the Department of Psychology walked in and said a few words in the old professor's ear, and the old professor looked at Zhao Yuean.

"Zhao Yuean, go to the office with the director."

Zhao Yuean looked at the head of the department, took the white paper he had just sketched, and followed him out expressionlessly.

When he came to the office, Zhao Yuean saw a tall, sturdy and upright-looking man sitting on the sofa, his hands and fingers touching, thinking about a problem.

"Yue'an, this is Captain Guan of the Municipal Criminal Investigation Brigade, and I want to know some questions from you."

Zhao Yuean looked at Guan Li, feeling where he had seen it.

"Classmate Zhao, it's been a long time."

"Have we met?"

Zhao Yuean looked at Guan Li directly, with bottomless black-brown pupils, Guan Li was a little weak-hearted.

"Five years ago, I took over your parents' case."

Zhao Yuean remembered that a police officer had indeed come to her house after her parents died and tried to comfort her.

"It's been a long time, and the case hasn't been closed for so long."

Zhao Yue'an said coldly, and Guan Li, who was choked, didn't say a word for a long time.

After a long time, Guan Li said: "I will not give up on your parents' affairs, and I will definitely give you an explanation." I'm here today for another case.

Did you go to the Baifeng community a few days ago? ”

Zhao Yuean didn't speak, Guan Li glanced at the head of the department, and the other party left the office with interest.

At this time, only the two of them were left in the office, and Zhao Yuean sat opposite Guan Li.

"Is Captain Guan suspicious of me?"

"You are the only one who has said the location of the body and the most calm, unless you can give a reasonable explanation, the team will also designate you as a preliminary suspect by virtue of surveillance."
