301, Building 9, Niutang Community, Zhaojiatang, Xizhong Road, Fang Junlong was knocking on the door of the house next door.

"Knock knock."

Someone inside asked, "Who?" ”

"Hello, we are the police, and we want to ask you about the situation."

"Why did you ask again, I've asked dozens of times."

Inside, the door was opened, and it was an aunt with a dissatisfied expression, frowning: "Didn't you say everything that should be said?" Didn't hear anything. ”

"I just want you to think about it, between 2 and 5 a.m., if there is any wind and grass, a small noise next door, or the sound of footsteps in the hallway, anything that is wrong, you can think about it again."

"I really haven't heard anything, you've asked many times, my children are going to school in other places, and my husband and I are at home, both of us can be sure, there is no movement at all."

"Okay, sorry to interrupt."

Waiting for the other party to close the door, Fang Junlong turned his head and his face was very solemn.

Criminal policeman Xiao Liao said: "Boss, the comrades from this police station have all helped to ask, but there are no clues. The old-fashioned residential area of Niutang Community is inhabited by elderly people who go to bed relatively early. Hu Jie grew up in this community, and after his parents died, he lived alone, and he did not intersect with the residents here. Nearby residents reported that he had complex social relations, and that he had many friends who called him brothers and sisters outside, and that they were often seen holding banquets at home, making noise and affecting the lives of nearby residents. It makes everyone here hate him and don't pay much attention to his situation. So it's hard for the residents here to provide any valuable clues. ”

Criminal policeman Zhang Yu also said: "The bar that Hu Jie frequents will not open until the evening, but according to Hu Jie's Ma Zai, Hu Jie has a lot of enemies outside, even those staff or acquaintances in the bar he frequents, there are no less than 10 people who have the motive to kill him, not to mention the enemies who fight and make trouble outside." ”

"The preliminary inquest by the forensic doctor showed that the murderer killed him with a knife, the wound was incised, the wound was smooth and neat, there were no irregular injuries, and the technique was so clean and neat. Either he was a doctor with a scalpel or a butcher in the vegetable market, or he had a deep hatred for him and insisted on killing him. I feel like the latter. ”

"Most of the surveillance in the vicinity is concentrated at the traffic light intersection, and the traffic police have been asked to find any valuable clues. The terrain of this community is complex, there are dozens of trails that can be interspersed, and there are many options for hiking in, so there is no need to take the big road at all. ”

Several members of the criminal police team reported the clues they had searched so far, and the more Fang Junlong listened, the more ugly his face became. Although this case is an ordinary homicide case, because it involves the son of the director, there is a lot of pressure from above. If the case can't be solved for a day and the truth is revealed, then the suspicion of the director's son can't be cleared up for a day. This is an intolerable shame for both the high-ranking provincial and departmental directors and the public security system. So once the case reaches an impasse, it will be a very headache for Fang Junlong. If Zhou Yunkai is not involved, the case can still be carried out slowly, but when it is involved, according to the instructions above, the case must be solved as soon as possible.

Where to go to find clues, although the probability of vendetta is very high, but there are too many enemies who can't stand the victim. Even if you investigate in this direction, just figuring out all of Hu Jie's social networks and checking all the enemies who hate him to the bone will take ten days and half a month, or even longer.

If you accidentally check the wrong direction, it will be even more troublesome. Not to mention wasting precious time to solve the case, all clues are interrupted and you have to start all over again. It will make the already clueless case more complicated and more difficult to solve.

Thinking of this, Fang Junlong was also upset and said, "Xiaoyu, you take someone to the bar at night." Xiao Liao continued to check the surrounding area, and I went to the forensic doctor's side. ”

At present, we can only find a way to see what specific results the forensic doctor has.

The task was assigned, and at that moment, the phone rang.

Fang Junlong saw that it was his unconscious nephew again, because when he was solving the case, he was in a troubled mood, so he didn't want to deal with Lin Ming, so he pressed the computer down. But after a while, the phone rang again, and Fang Junlong could only answer the phone while going downstairs to the police car.

"What are you doing, my little ancestor, didn't you let Zhou Sheng tell you about the case? I'm following up on the clues, and I'll talk about it later. With that, he was about to hang up the phone, light the fire and drive to the forensic doctor.

But at this time, Lin Ming said: "Uncle, don't hang up, I have clues." ”

"Clues?"

Fang Junlong's copycat mobile phone was loud, and although his hand was pressed on the hang-up button, he could still hear the sound in the earpiece. Hearing that there was a clue, he immediately responded: "What clue?" ”

Lin Ming said: "The murderer hid under the bed the day before and waited for the opportunity to commit the murder, not through the window. ”

Fang Junlong said with a solemn face: "How do you know." ”

"Guess."

"We know that, too." Fang Junlong said: "In the water pipe and the anti-theft net on the second floor, I found some traces that had been wiped. The murderer did not want to expose his shoe prints, because the shoe prints could be used to infer information such as the height and weight of the murderer. So after committing the murder, climb down and clean up the marks at the same time. However, we did not find these items on the security net on the first floor, which indicates that the murderer did not climb up from below at first, but used some method to enter the room through the door. When leaving, I left through the window. Climb to the second floor, clean up the marks, and then jump off the top so that you don't leave traces on the security net on the first floor. ”

Lin Ming didn't expect the police to be so efficient, and they had already found the murderer's modus operandi. Of course, this method is not clever. There is no so-called secret room, no so-called suspense killing, and no so-called high-tech killing methods, just an ordinary premeditated crime.

But it is difficult to solve such a case, because the murderer only needs to remove all traces of himself at the crime scene, leaving no fingerprints, hair, shoe prints and other valuable items, and it is difficult to lock the suspect.

In addition, the social relationship of the deceased is complex, which is quite difficult for investigation. The most important thing is that the property at the scene was not stolen, and no one will benefit from the death of the deceased, so it is very likely that there is a grudge against the deceased. Although it is certain that more than 80% of them are vendettas, the point is that there are too many enemies of the deceased.

In the bar where the deceased frequented, there were no less than a dozen people who had a motive to kill him. Not to mention people who usually complain in life, or even in private. So this kind of case is very difficult to solve.

Lin Ming said: "In addition, I also know the source of Zhou Yunkai's fingerprints. ”

"Where did it come from?"

"It's supposed to be a school."

"I see. Could it be that Zhou Yunkai met the suspect by chance during the previous investigation, and the suspect recorded his appearance, so as to investigate him, and after discovering his background, he went to the school to copy his fingerprints? ”

"I guess so."

"Okay, another new clue. Go back to your studies and don't worry your mother. ”

"Uncle, what are you going to do?"

"Naturally, I asked the policemen who accompanied Zhou Yunkai to see if they had any memories of the suspect during the process."

"Take me."

"Don't mess with children."

Saying that, Fang Junlong planned to hang up the phone again, for the clues provided by Lin Ming, although it was not a big clue, it also had a certain value. This at least shows that the suspect had investigated Zhou Yunkai before going to the school to get fingerprints.

A national school like City No. 1 Middle School not only has a lot of monitoring installed in the school, but also in each class. If the suspect really took fingerprints from the school, then something could definitely be found.

Lin Ming hurriedly said: "I have more important clues, if you don't bring me, I won't say it." ”

"You." Fang Junlong was a little annoyed and said, "Don't go too far, Lin Ming." ”

"Anyway, I just want to follow you to watch the case."

"What clues do you say first?"

"Uncle"

"Huh?"

"Do I look like a fool?"

"It's like."

“......”

Lin Ming said speechlessly: "Then I don't care, if you don't take me, I won't say it." ”

There was silence for a moment, and after half a minute, Fang Junlong said, "Where are you now, are you still in the team?" Wait for me there. ”

The Chengguan District Criminal Investigation Brigade was not in the Public Security Bureau, but entered in an alley on Wuxing Road, diagonally opposite the Wuxing Road Police Station. It is in the same courtyard as the Chengguan District Fire Brigade, so the Chengguan District Forensic Center, which is subordinate to the Criminal Investigation Brigade, is not in the Public Security Bureau, but in the courtyard of the Criminal Investigation Brigade.

Forensic Medicine, also known as the Technical Department or the Forensic Science and Technology Unit. Their work is not just as simple as autopsy as ordinary people imagine, but also trace identification, on-site investigation, toxicological reaction, psychiatric evaluation, etc., all under the management of forensic medicine.

For example, on-site photography and evidence collection, fingerprint identification, DNA identification, investigation of the murder weapon or residues at the scene, the mental state of the suspect, etc. So the responsibilities of a medical examiner are actually quite large.

Lin Ming waited for Fang Junlong at the door of the criminal police team, and Fang Junlong went in without saying a word and walked in the direction of the forensic team.

The two of them walked through a corridor to the second floor of the backyard, which was eerie, hot in summer, but there was a strange turbid and damp atmosphere. People who have been to a funeral home may have this feeling, because there are many freezers in the morgue, and when the cabinets are opened, the cold air mixed with the smell of corpses will produce this strange feeling.

"You stay here and don't move, it's a dissected corpse inside, do you understand the autopsy? The smell of corpses, the view of giants, the decay, not to mention the disgusting scene, the smell alone can make you vomit out your overnight meal. Fang Junlong was scaring Lin Ming at the door.

Lin Ming was so easily intimidated, pointed to the office inside the door and said, "I'll just sit here and wait for you." ”

Fang Junlong glanced at him, turned around and went in without making a sound.

Entering the office is the office, and there is a door leading to the dissecting table inside, and there is a curtain on the door that is not completely transparent, and you can only see faintly people on the side of the dissection table from the outside, as if it is a mosaic. The imaginary smell is not there, but there is a mysterious smell of fragrance and strange smells.

Think about it, Hu Jie died in the early hours of the morning, he was dead for only ten hours, and the corpse has not yet decomposed, where does the corpse smell come from. As for the smell of mystery in the air, it is likely that it was born from the morgue in the dissecting room, mixed with perfume to dispel the smell.
