When Jiang Cheng heard the news, he rushed to the cordon, he showed his ID and crossed the cordon into the corridor, the more he went up, the more worried he was, not only was there garbage piled up in the corridor, but there was a foul smell wafting in the air from time to time, and he said to his colleagues next to him: "Lao He is here, you have to strangle me." ”

A colleague answered: "Team Jiang rest assured, the gloves and masks have been prepared for Professor He." ”

Jiang Cheng extinguished the cigarette at hand and crossed the pile of debris in the corridor, "Okay, you kid, you have made progress." ”

Jiang Cheng approached the house and saw the corpse on the ground, the girl lying in a pool of blood had a pale face, her mouth was slightly open as if she was about to say something, and her eyes were hollowly tilted sideways with her head and hands in the same direction. He took the glove belt from his colleague. "Sister Zhang, what's the situation. ”

Zhang Hao, a forensic doctor who was squatting on the ground for a preliminary examination, heard a low voice from behind, stood up, and glanced at the deceased, "The time of death was about one o'clock in the morning, and I was found by a neighbor at ten o'clock this morning. She paused and continued, "The deceased is suspected to have been injected with an air needle, and an autopsy is required to determine whether the death was caused by the air blockage or a wound to the chest. ”

Jiang Cheng frowned slightly, there was no emotion on his face, he squatted down and lifted her cuffs, and there were obvious traces of purple on his skin. "Who else lives in the house but the dead?"

Song Bin, who was surveying the scene, said: "The roommate who lived with her moved out a month ago, and she is currently the only one living alone. ”

Jiang Cheng heard the familiar voice outside the door, so he stood up and walked out, giving a big hug to the visitor.

He Yan, who was wearing a mask, pushed him away and took a step back, with a slight dissatisfaction in his tone: "Now the police don't even have the ability to handle cases?"

Song Bin heard the meaning of his words, and hurriedly put aside the charges and transferred to Jiang Cheng, "Team Jiang asked me to fight." ”

Jiang Cheng whispered to Song Bin beside him, "How many calls did you call him?"

"Twenty-seven. ”

Jiang Cheng glared at him, then touched his nose.

"It's really unpleasant. ”

Jiang Cheng knew that what he said was the environment in the community, and said flatteringly: "Didn't you come with equipment?" ”

"I asked your people to buy it. He Yan glared at him.

"Next time, I'll put some disinfectants in the car for you to make sure you are clean. ”

"Don't be poor, go to the scene and see. ”

He Yan looked around the room, there were only simple furniture and daily necessities in the room, although the furniture was shabby, it was very neat, the items were placed in an orderly manner, and there was no trace of turning on the scene. On one side of the wall was a long table, and on top of it, there were many books piled up densely and neatly. His gaze stayed on the photo on the table, he picked up the photo, Jiang Cheng leaned his face over, and said, "It's a pity that a little girl as old as a flower was brutally killed." ”

He Yan looked him up and down, put down the photo in his hand, and teased: "What's the matter?"

"I'm emotional, you know. ”

He Yan took a few steps forward and squatted in front of the corpse, carefully examining the deceased's condition. "The wound is less than 3 centimeters from the heart, which is not enough to be immediately fatal, the burn on the body was two days ago, the deceased was injected with an air needle, the ring on the ring finger is large, and the letters engraved on the wrist are the same as on the ring. He stared at the corpse of the deceased, frowned, and fell into deep thought.

Jiang Cheng gasped. "It can't be related to the last corpse shredding case, right?"

He Yan replied: "Judging from the depth of the letters engraved on the wrist, I am not sure that it is the same murderer at this time." ”

Jiang Cheng looked at him in disbelief. "You can see it. ”

He Yan frightened: "I have practiced." ”

Jiang Cheng looked at the corpse with his hands around his chest, and said, "If it is the same murderer, why is the method of committing the crime inconsistent, is it because he feels that the corpse is a waste of time, so he chooses to use other methods to commit murder?" His brows gradually twisted into a ball, and then he said: "Another possibility is that if the murderer imitates the corpse fragmentation case, then why did he only engrave letters on the deceased's wrist, because something caused him to have no time to destroy the corpse?"

He Yan looked around, most of the white walls had already turned yellow and black, "It's not that simple, let's go to the other side to understand the situation first." ”

Jiang Cheng stood up and walked out first, raising his hand and about to knock on the door opposite, when he was interrupted by a sharp voice.

I saw that the person who came was about forty-five or sixteen years old, with short pure black hair slightly curled, a high proportion of fat, and wearing a red dress that did not match her figure. ”

Jiang Cheng blocked her way and said, "Are you the landlord?"

The landlady glanced him up and down, and replied angrily, "Who are you?" ”

"Police. Jiang Cheng took out his ID to prove his identity.

The landlady was in an unusually high mood, like an enraged lion, with a mouth like a machine gun, and kept saying: "Tell me, it's not good for people to die, but to die in my house, it's really eight lifetimes of blood mold, who will dare to rent my house in the future." ”

He Yan, who stayed on the right side of Jiangcheng, said, "Human life is at stake, and the house is not rented." ”

The landlady's eyes flashed with uncontrollable anger, and said: "I said that you can't speak, you think I want her to die, if it weren't for her being a poor girl, I would be too lazy to meddle in things." ”

"Eldest sister, don't be angry, I have to take the initiative to cooperate as a citizen in the murder case, you say yes?"

After Jiang Cheng finished speaking, the landlord looked at He Yan with a slight dissatisfaction in his tone. "Look at how people talk. ”

He Yan: "......"

Jiang Cheng asked: "Did you notice any suspicious people in the community last night?" ”

The landlady looked panicked in her eyes, avoided his gaze, and said, "No."

"It is said that the community has reached the time of demolition, and it is forbidden to move in the community, and you have rented the house to others without permission, and now you are afraid that you will be responsible for the death of someone. ”

When the landlord heard his words, he couldn't help but be a little nervous: "I can't help it, we don't even have a place to live now, and besides, I am also kind to that girl, who knew that such a thing would happen." ”

"I hope you will cooperate with us and bring the murderer to justice as soon as possible. ”

"Yesterday I went downstairs for a walk after dinner, and when I came back, I met a man in the corridor on the sixth floor who came to look for her. ”

"How do you know it's looking for her. ”

"Most of the residents living here are elderly, and then there are tenants from outside, and the houses that are demolished are relatively cheaper for them, and the residents of this building have moved out, and there are only a few residents," the landlady said. Only that little girl lives with our family on the sixth floor, who else can I find if I don't look for her, and it is difficult for someone to come to me. ”

While the two were talking, He Yan re-entered the crime scene.

"Do you see his face clearly?"

"Not really, he wears a hat and a mask, and the light in the corridor is broken so he can't see clearly, but his face is not much worse in terms of figure. ”

Jiangcheng is embarrassed. "There are no more obvious features. ”

The landlady thought for a moment: "The obvious characteristic? He seems to be a cripple." ”

Jiang Cheng asked suspiciously, "Cripple?"

The landlady said uncertainly, "Yes, it's a cripple, I see that he walks in a way that looks a little like that." ”

After Jiang Cheng finished asking, he turned around and was about to return to the house, but was stopped by the landlady behind him: "Comrade policeman, what I said is the truth." ”

"Thank you for the lead. ”

After the body was removed, the rest of the investigators, except for the appraisers, left one after another.

When Jiang Cheng returned to the scene of the crime, he saw He Yan standing in front of the window and asked, "Is there any new discovery?" ”

"According to the situation at the scene, it is preliminarily judged that it looks like an acquaintance committed a crime. ”

"How can you be sure. ”

He Yan said: "The windows are well sealed, and there are no traces of breaking into the room. At present, there are two situations, one is that the deceased opens the door voluntarily, and the other is that the murderer forcibly enters the house after the deceased opens the door. Obviously, the latter is not valid, if the murderer forcibly enters the room, the deceased will first be pushed to the side by the murderer and enter the room himself, but no footprints of the deceased are found on either side of the doorway. ”

Jiang Cheng looked at the clean and tidy scene. "Will the site be cleaned? ”

Song Bin interjected: "How can you see it?" ”

He Yan picked up the white ceramic cup from the table and handed it to Jiang Cheng.

"What for. Jiang Cheng asked puzzled.

"There was blood on the rim of the cup. ”

He looked around and didn't see it, and said, "Where?"

He Yan raised his finger and pointed a little.

Jiang Cheng looked at him incredulously, and he could see the bloodstains that were almost invisible to the naked eye. "Lao He, your naked eye radar is really not in vain. ”

He Yan replied disapprerovingly: "I said that you can send some more people in your team to let me be more idle." ”

Jiang Cheng complained to him: "Don't, you don't know that you are not here, and the cases have been going on one after another these days. ”

"That's a problem with your abilities. ”

"Yes, yes, yes, our whole team together is not as good as you alone. ”

"That's right. ”

Jiang Cheng patted his ass and said: "Who doesn't know that you are a master in the world of solving cases, and the chances of having you help us solve cases will be greater, right?"

"Your police affairs, I'm fooling around. ”

"How is this blind peace, you are maintaining world peace, and I will tell you a good news later, so that you are satisfied. ”

He Yan said with certainty: "It's not good news for me. ”

Jiang Cheng changed the topic: "Let's look at the scene first, and we'll talk about the news later." ”

Jiang Cheng put the cup into the physical evidence bag and said to Song Bin: "After sending it to the identification department, you will go back to the team directly." ”

"Then how do you go back.

Jiang Cheng's right hand was on He Yan's shoulder and said, "He drove me." ”

He Yan glanced at the hand on his shoulder, and Jiang Cheng took a step back in surrender. "Someone should cure your cleanliness. ”

He Yan ignored his words, turned to leave, and Jiang Cheng behind him shouted, "Wait for me." ”

Xiao Jingyao, who was standing in the courtyard of the criminal investigation team with her suitcase, asked the two policemen who greeted her, "Hello, is Jiang Cheng working here?"

"Who are you?" said one of the officers.

"I'm his sister. ”

"I remember that Team Jiang is an only child, where did I come from. ”

Another colleague standing beside him looked understanding, and hurriedly said: "He is working, but he is not in the bureau, if you don't wait for him in the office, go up to the second floor and turn right into the third office from here." ”

"Okay, thanks. ”

Xiao Jingyao came to the second floor, opened the door of the hall and walked in, except for Xiao Qin on duty, the rest of the people in the office were all out for work, Xiao Qin got up and asked when he saw someone coming, "Hello, who are you looking for?"

She replied politely: "Hello, I am Jiang Cheng's sister, and he asked me to wait for him here." ”

"Team Jiang has gone out to handle the case, you wait for him here for a while. With that, he brought out a glass of water from the pantry.

Xiao Jingyao, who was sitting in a chair, stood up, took it, and nodded at her. "Thank you. ”
