"You mean the killer cleaned up the scene after committing the crime?" Captain Xu asked.

Director Qiu of the Criminal Division nodded solemnly, and then further explained: "However, the deceased may have been entangled with the murderer before his death. We have collected some hair samples on the clothes of the deceased that clearly do not belong to the deceased, which may be a key clue to solve the case. ”

"I'm glad I got you." Compared with Captain Xu's anxiety, Deputy Director Xia was very calm, "Deputy Director Xiao and your Captain Liao will arrive in a while, and I may have to trouble you to explain the situation here to them again." ”

"Of course." Director Qiu of the Criminal Division readily agreed, and then turned around and entered the building again.

"Why don't our people go and have a look?" Deputy Director Cui finally seized the opportunity to speak, he seemed to be giving Huang Fangyuan an order, but in fact, he was asking Deputy Director Xia's opinion on the side.

Hearing this, the others had not yet reacted, but Chen Kangle couldn't resist his eagerness to try, and put on a posture of gearing up and preparing to do a big job.

Deputy Director Xia immediately understood, and said with his head bowed: "This case still has to be handled by you to cooperate with the investigation." Lao Huang, you can take your people to the scene of the crime to have a look! After that, he said to Deputy Director Cui, "It is estimated that after Deputy Director Xiao and the others arrive, the Criminal Investigation Corps will officially take over the investigation." If a task force is formed, it is very likely that the on-site headquarters will be set up in your office as it was last time. When you get back to the office, you make arrangements to free up an office or a meeting for you. ”

"Okay." Deputy Director Cui replied respectfully.

"The serious crime team of our sub-bureau is currently limited in manpower, and I think this time I will let Lao Huang and them cooperate in the investigation of this case." Deputy Director Xia thought for a moment, and then said, "They performed very well in that case last time, and they also cooperated with the criminal team very well. This time, I believe that they will be able to cooperate with the criminal squad to complete the mission well. ”

"Lao Huang has always been the best police officer we have." Deputy Director Cui praised his own people without hesitation, and his face showed a sense of pride that could not be concealed.

On the other side, Huang Fangyuan had already entered the scene of the crime with Ge Bin and others.

It is an old-fashioned public house built in the 80s of the last century, with four floors and four households on each floor. On the right hand side of the door is a staircase leading to the second floor, and room 101 is located at the bottom of the stairs, the innermost room at the end of the corridor.

This is a two-bedroom apartment of less than 40 square meters, a typical old house in the style of the last century, with a cramped layout and unreasonable settings. The entrance leads to the aisle kitchen, with the gas stove and sink placed under the window on the right-hand side to the north. Walking along the left-hand side is a south-facing bedroom, with an area of nearly twenty square meters, and the deceased is lying on the ground of this bedroom; On the opposite side of the south-facing bedroom, which is separated from the kitchen by the hallway, is a small north-facing room with an area of about 10 square meters. Between the two bedrooms is a bathroom measuring less than four square meters.

After Huang Fangyuan walked around, he focused his investigation on the south-facing bedroom. And Chen Kangle is like a cheerful puppy, wandering around the house.

"Huh? This deceased has a habit of cleanliness! Chen Kangle stared at the cabinet under the kitchen sink and teased.

"What did you find?" Lin Xuan followed closely.

"Look." Chen Kang motioned to Lin Xuan to look at the cupboard, and five bottles of 84 disinfectant appeared in the open cabinet door, "Five bottles of disinfectant have been hoarded here at once, how much does her house cost disinfectant?" Chen Kangle subconsciously looked around, and suddenly said confusedly, "But this house is not neat and tidy!" Although there are not many items, they are placed in a disorderly manner, and at first glance, they are thrown there casually and piled up haphazardly. She pointed to the greasy spot on the stove again, "You see the grease here is blackened." ”

"Maybe it's not her own sanitizer." Lin Xuan thought for a moment and gave a reasonable explanation, "She is engaged in the domestic service industry, maybe these disinfectants are used to clean the employer's house." ”

Chen Kangle thought about it sideways, and felt that Lin Xuan was reasonable, so he didn't ask any further. After a while, she reached for the inside of the cupboard again.

"Stop!" Lin Xuan broke off, making Chen Kangle tremble, and his outstretched hand froze in the air, "What do you want to do?" Objects here are only allowed to be seen, not to be moved. ”

"Haven't all the people in the criminal department already investigated? Why can't you move yet? Chen Kangle asked aggrievedly.

"You can't turn through the animals here until the lockdown is lifted, and it won't be good if you leave traces and destroy the scene. Before the case is solved, it may be necessary to conduct a second investigation of the crime scene, and everything here must be maintained as far as possible at the time of the crime. Perhaps because he felt that his previous roar was a bit excessive, Lin Xuan tried to keep his tone as soft as possible, "There was a real case where a young community police officer had a homicide case in the community under his jurisdiction, and he was the first to arrive at the scene of the crime after receiving the report. This was his first encounter with a homicide case as a police officer, and he seemed a little flustered. Because his hands were exposed to some oil on the way to the crime scene, he washed his hands in a sink at the crime scene while waiting for police reinforcements. Unbeknownst to them, they later collected a blood sample at the edge of the sink. At that time, the experienced old criminal police judged that the murderer himself may have been injured when he committed the crime, which was accidentally dripped by him while treating the wound. Because the location is hidden, it was not cleared by the murderer. However, this only important piece of evidence that can identify the murderer is invalidated because of a fingerprint......"

"That fingerprint can't be left by that little policeman, right?"

Lin Xuan nodded with a stern expression: "It was the young policeman who left his fingerprints at the scene of the crime when he washed his hands, which made the key evidence flawed. The defense lawyer of the criminal suspect seized on this point and bluntly pointed out that this was a deliberate attempt by the public security organs to solve the case......

"How is this possible?" Chen Kangle once again interrupted Lin Xuan's narration, and said indignantly, "If there is no injustice or hatred, why should the police frame him for blame?" Besides, where did the police get his blood? ”

"Not to mention, the police really have a blood sample of him."

"What?" Chen Kangle looked surprised, and his voice unconsciously became louder.

"He had previously been arrested by the police for drug use and drug trafficking, and his blood samples were taken according to the procedure. This is also one of the important bases for the defense lawyer to insist that the police deliberately planted the blame. He said that the suspect had a holiday with the police before and became a thorn in the side of the police. In order to close the case as soon as possible, the police used this method of killing two birds with one stone and falsifying evidence to blame the suspect. ”

"This defense lawyer is so dark-bellied and imaginative, he is very suitable to be a writer." Chen Kangle grinded his back molars and said angrily, "And that little policeman is too ignorant, how can he make such a common-sense mistake?" One of his inadvertent actions caused everyone's hard work to come to naught, which was simply too much. If you want me to say that you should fire this man. She seemed to get more and more angry, and after a short pause, she was still a little angry, "But even if you fire that little policeman, it won't help!" Was the suspect convicted later? ”

Lin Xuan has been patiently listening to Chen Kangle's angry words, and from her words, he can feel her passion and dedication to the profession of the police. Nowadays, most young people from the police are motivated by personal interests, and it is rare to see someone like Chen Kangle who loves this profession from the bottom of his heart, and Lin Xuan can't help but be a little impressed by her.

Because his attention was diverted to other places, he didn't care about what Chen Kangle said or asked later, and he didn't respond to Chen Kangle's question.

Chen Kangle saw that Lin Xuan didn't react, so he turned his head sideways to look at him, but he didn't want to see a smile on his lips. Chen Kangle seemed to misinterpret the smile, and suddenly shouted loudly: "Lin Xuan, are you deliberately making up nonsense to tease me?" In fact, there is no such ignorant little policeman, and there is no such homicide, right? ”

"No, Lin Xuan didn't tease you, this is the truth, the ignorant little policeman who made mistakes is me." Huang Fangyuan's deep voice sounded behind the two of them.
