A new detective team was established, and the four of them briefly introduced themselves to each other, and they were familiar with each other, Chu Ming and Shu Xiaoran's personalities were easy to get along with. It's just that Qin Jian and Ling Yu's tempers are still cold and arrogant.

All four of them have outstanding abilities, and in response to Tang Hong's case, they quickly launched an investigation into the matter. Tang Hong's body had been transported to the autopsy room, and Shu Xiaoran alone tried to extract some useful clues from the autopsy room in the autopsy room.

In another room, Ling Yu, Qin Jian, and Chu Ming began to analyze the incident from the photos taken at the scene.

Chu Ming called up the surveillance video of Tang Hong's clothing store that night, and at about half past nine in the evening, there was no one in the store, only Tang Hong alone. At about 9:50, Tang Hong had already put on his coat and was about to leave, but when he was about to turn off the computer, he stopped for a while, and then sat down in front of the computer. Then it was very strange that the surveillance was suddenly completely black, without any information, and there was a "bang" sound. Someone must have deliberately broken the surveillance.

According to the clues previously obtained, Tang Hong died at around 12 p.m. on July 6. The deceased did not have any enemies during his lifetime, it was not a revenge crime, the cause of death was a cut throat, and the knife edge was intact and not rugged. The murderer did not commit the crime in a hurry, and he did not have a conflict with Tang Hong in the store that night. This should be a targeted planned crime.

Besides, generally speaking, Tang Hong's clothing store should have closed at ten o'clock in the evening, and the murderer must have known what reason Tang Hong had to stay in his clothing store that night, or in other words, what method did the murderer use to make Tang Hong not leave the clothing store at twelve o'clock that night. This is most likely the reason why Tang Hong stayed strangely in front of the computer at around 9:50.

At this time, Shu Xiaoran entered the room and brought the autopsy results.

From Tang Hong's corpse, Shu Xiaoran saw that Tang Hong's arms and the back of his neck had slight bruises, and there were marks of beating on the back of his head, which should have been fists in terms of strength, but he did not leave any relevant fingerprint clues. From this point of view, Tang Hong should have had a scuffle with the murderer before he died, but he was obviously not the murderer's opponent, and after being knocked out from behind by the murderer, he was brutally cut his throat. The cut in the throat is cut flat and the force is evenly distributed. It's almost just a stroke.

According to Shu Xiaoran's practice report, the murder weapon that cut Tang Hong's throat was like a razor blade or a sharp weapon such as a gadget knife.

Ling Yu asked Chu Ming to search the purchase records of various commodity stores on the Internet, and found no record of buying such a sharp weapon recently. There are no important clues in the monitoring, and the only valuable thing is the moment when Tang Hong stays in front of the computer. It's just that the surveillance behind it was destroyed, and I didn't see what happened to the crime. At about twelve o'clock in the evening, even if the clothing store is in the downtown area, there are few people on the street at that time, and besides, if the murderer is planning to commit the crime, he will definitely notice this.

Next, start looking for useful clues near the scene.

Chu Ming and Shu Xiaoran were around the clothing store, trying to find useful clues from the people passing by. Although this possibility is relatively small, it must not be missed. And Ling Yu and Qin Jian mainly work on Tang Hong's acquaintances, they must know some of Tang Hong's living habits, so that they can know the reason why Tang Hong sat in front of the computer that night, and even Tang Hong didn't leave the clothing store at twelve o'clock.

【Outside Tang Hong Clothing Store July 9】

Summer is the rainy season, the street has just been washed by a light rain, and Tang Hong's clothing store, which used to have a lot of customers, seems very lonely at this time. Standing at the door of the clothing store, although Tang Hong has been dead for three days, there is still a faint smell of blood outside the door, which may be the injustice left by Tang Hong.

Chu Ming and Shu Xiaoran were standing outside the clothing store, and there was no order from Ling Yu to enter the clothing store to look for clues. Chu Ming was holding a small computer in his hand, and from the device, he could detect some clues related to Tang Hong in the vicinity. Shu Xiaoran tried to find out the relevant news from passers-by on the night of Tang Hong's murder. But it's basically all in vain.

This kind of thing happened in Chengguang City, and before it was resolved, everyone's hearts couldn't be completely put down, needless to say, there was no one on the street at that time that night, even if someone saw the whole process of the crime, but at this time, they would say they didn't see it. Let a sleeping dog lie. No one wants to have anything to do with it.

On Chu Ming's side, he was trying to use his own equipment to detect the murder weapon that killed Tang Hong that night, but Chu Ming checked them one by one in every corner around the clothing store, even in the sewer pipes not far away, but he didn't find any clues.

There are not many clues found in Tang Hong's case, and now it has caught up with the light rain weather, which has undoubtedly added a lot of difficulty to the case. However, Chu Ming and Shu Xiaoran did not find nothing, although they did not find any clues related to the murder weapon, but in front of the window of the clothing store, Shu Xiaoran found some black powder.

Because of the eaves in front of the window, the light rain didn't fall here, but it was probably because of the rain, and it happened that some of the raindrops fell on the powder, holding them to the ground. That's why the breeze didn't blow them away.

Shu Xiaoran put on gloves and put the powder into a bag with the tools in his hand, ready to take it back for testing. Other than that, they didn't find anything more.

There are not too many clues now, so I can only wait here for Ling Yu's next order.

【Chengguang City Citizen Community】

On Ling Yu and Qin Jian's side, they came to Tang Hong's house and learned about Tang Hong's situation from Tang Hong's family.

came to Tang Hong's door, and after knocking on the door, it was a woman who opened the door, who looked about the same age as Tang Hong. After Ling Yu and Qin Jian entered, they learned that it was a middle-aged woman who opened the door, and there was a little girl behind her. learned from the previous information about Tang Hong that Tang Hong's parents died when she was a child and she has been living with her sister. After that, I relied on my own little efforts to have today's clothing store, and I had a relationship with someone in the early years, and gave birth to a little girl, but soon the two divorced, and the child was awarded to Tang Hong, so it seems that this middle-aged woman should be Tang Hong's sister. The little girl behind her should be Tang Hong's daughter. It's just that I didn't expect that the clothing store had just been improving for a few years, and it was actually killed, which hurt this girl who had no father and lost her mother.

Taking care of Tang Hong's sister's emotions, Ling Yu didn't ask some radical questions, but just learned some of Tang Hong's habits from Tang Hong's sister.

Most of them are some habitual behaviors in life, which have no value, but there is a very important clue about Tang Hong in the clothing store.

Although Tang Hong's clothing store has a good business, Tang Hong has always taken care of the entire clothing store alone, and there is no need to hire someone to take care of it, even if he is tired, but he has a very fulfilling life every day.

There is only one monitoring of the clothing store, and it is the one that Chu Ming called out at that time. Another important clue is that Tang Hong would check today's bill on the computer every night at ten o'clock before the clothing store closed. Because my clothing store has been running for a long time, there have been basically no problems, so I habitually glance at the bill every night before closing.

In addition to these, Tang Hong's sister did not mention any useful clues, as for whether Tang Hong had any offended people, or people who had conflicts in business, these were not mentioned at all.

When Ling Yu left, she glanced back at Sister Tang Hong who was standing at the door to see her and Qin Jian, her only sister was killed, and she still doesn't know what the reason is, her eyes are deeply sunken, I don't know if she has closed her eyes in the past few days, and the bloodshot eyes are overlapping one by one, just like the blood left on Tang Hong's corpse. is obviously about the same age as Tang Hong, but he looks ten years older than before. A woman's face is the best proof of the age of a woman's temperament, but she is now an old man with a few cruel cuts.

【Tang Hong Clothing Store】

With the clues they learned from Tang Hong's sister, Ling Yu and Qin Jian came to Tang Hong's clothing store and found Chu Ming and Shu Xiaoran. Since Tang Hong's body was transported to the autopsy room, Tang Hong's clothing store has been cordoned off, and no one is allowed to enter without an order.

Ling Yu had previously applied to the above through Director Bai for the right to enter and search.

In the clothing store, Chu Ming came to the computer and tried to search for some information from Tang Hong's computer. Qin Jian looked at the situation of the clothing store at this time, most of the clothes were hung in place intact, only the place where Tang Hong's body was a little messy, and it could be seen that there should be a fight with the murderer here. Qin Jian closed his eyes, and tried to emerge the scene in his mind.

Qin Jian's mind simulated the crime process, at first Tang Hong should be in the location of the computer, but then from ten o'clock to twelve o'clock, Tang Hong came to this place with the murderer for some reasons, from the bruises on the corpse, the murderer should have faced Tang Hong face to face first, and then, directly stepped forward, strangled Tang Hong's neck with one hand, and grabbed Tang Hong's arm with the other hand, and then Tang Hong began to struggle, resulting in many bruises on his body.

The purpose of the murderer's killing of Tang Hong is not clear, but it can be seen from the wound that he does not want to complete an imperfect work of art.

In order to stop Tang Hong's struggle, the murderer directly hit the deceased in the back of the head with his fist, causing the deceased to be in a brief coma at that time, and then the murderer took out his crime tools, enjoyed the process of cutting his throat, and completed his criminal artwork.

At the end of the simulation, Qin Jian opened his eyes and looked up to see Ling Yu standing at the surveillance camera.

Qin Jian stepped forward and asked Ling Yu if he had found anything.

Ling Yu pointed to the surveillance camera above his head, Qin Jian noticed that the camera had been damaged, and Shu Xiaoran had not extracted any relevant ingredients from the broken camera. But some gray powder was found under the camera, and Shu Xiaoran put it in a bag and prepared to take it back for testing.

Look at the broken condition of the camera.

This is not like a kind of impact caused by concentrating force on one point, the damage is spread around one of the places of the camera, and a "bang" sound was heard in the surveillance video retrieved by Chu Ming before, and it is very likely that this sound caused the camera to be destroyed.

At the same time, Chu Ming found the bills of the last few days that had been cleared in Tang Hong's computer. Things like bills, Tang Hong generally don't get rid of them easily, and it seems that the murderer should be the only one who does this in the last few days, Chu Ming restored this bill and saved it in his computer.

A total of clues were found this time, but the only pity is that there have been no clues about the murder weapon. Synthesizing these clues, the detective team was ready to call it a day and returned to the bureau to begin to discuss the case.

Close the door of the clothing store, and maybe no one will come here again.

【Chengguang City Public Security Bureau】

At present, all the clues that can be searched have now been searched by the detective team, and the next step is to start their own reasoning and investigation based on these clues.

Previously, Qin Jian had simulated the entire crime, and in addition to the process of fighting, there were still several doubts that had not been solved. One is Tang Hong's stay on his computer before closing the door, and the other is how the surveillance was breached.

Chu Ming analyzed the bills in Tang Hong's computer, and then searched for relevant logistics information. He found that one of the bills did not match the number of the logistics, and it is still unclear what caused it. However, it is very likely that it was because this bill was not reconciled that Tang Hong stopped in front of the computer to check.

However, Chu Ming was very strange that this bill should not be considered a large amount of finance for Tang Hong, even if Tang Hong wanted to check it, there was no need to check it in the store until nearly ten o'clock in the evening for this small amount of bill. It's weird at that.

When Chu Ming was puzzled, Shu Xiaoran brought the test report of the black powder and the gray powder.

In fact, when extracting the black powder, Shu Xiaoran smelled that the black powder was gunpowder, but he took it back and checked it just in case. The gray powder is the dust of metal oxides. Metal oxide dust is a substance produced after the explosion of a firecracker, and it just so happened that the powder of gunpowder was found in front of the window.

Combined with the condition of the damaged camera, as well as the sound before the camera was destroyed, it is speculated that the damage to the surveillance camera is likely to be a small firecracker, which is not very powerful, but enough to destroy the camera.

Thinking of this, Ling Yu asked Chu Ming to play the surveillance video of that night again.

What she wanted to see most was the last moment, and sure enough, at the end of the video, there seemed to be a dark shadow flashing before the sound came.

Ling Yu asked Chu Ming to repeat this clip a few times, and finally let him stay for a few tenths of a second before the end, and captured this black shadow. Zoom it in, and it's really a small firecracker. I just don't know how it was launched.

Now that the reason for the destruction of the surveillance has been solved, there is another doubt that Tang Hong stayed in front of the computer because of this small bill. Ling Yu recalled the previous scene in Tang Hong's clothing store, the arrangement of each costume, the classification of colors, and the layout of computers and windows. Combined with monitoring what can happen within two hours of being breached.

Her eyes widened, and she had a hole in her mind, but she wasn't sure if the idea was right.

Ling Yu called Chu Ming: "Previous information shows what month was Tang Hong born?" ”

Chu Ming skillfully typed and added on the computer keyboard, and then all of Tang Hong's information was displayed on the screen.

"Late August." Chu Ming replied.

Hearing this, the corners of Ling Yu's mouth rose slightly, and she muttered:

"Sure enough, August tail, Virgo!"

"What? Virgo? Chu Ming didn't understand.

That's right, most Virgos have behavioral obsessive-compulsive disorder, and their perfectionist personality makes them habitually solve anything as long as there is a little bit of trouble, and they will not put it off again and again.

Although it is a bit far-fetched to conclude that Tang Hong has a slight obsessive-compulsive disorder based on the clue of the constellation, this is a hypothesis, and once this assumption is established, it will be a great help to the whole case.

Speaking of obsessive-compulsive disorder, Chu Ming, Qin Jian, and Shu Xiaoran both seemed to understand something.

Assuming that Tang Hong really has obsessive-compulsive behavior, she finds a discrepancy between billing and logistics in front of the computer, so she will definitely check it carefully, and when she sits in front of the computer, her eyes just can't see one of the windows. At this time, the murderer used firecrackers to destroy the camera, and it is not clear what method was used.

The killer should have destroyed the camera for two purposes, one is to cover up his criminal behavior. On the other hand, since he can use Tang Hong's obsessive-compulsive disorder to do something on his bill, if the camera is destroyed, Tang Hong must not be able to bear to wait until tomorrow, around ten o'clock is not too late for most people, Tang Hong may immediately call someone to repair the camera.

For the murderer, even if he knew that Tang Hong had obsessive-compulsive disorder, after all, there was no complete guarantee that Tang Hong would definitely call someone to repair it, so he was gambling, but this bet was so confident for himself. As long as Tang Hong calls someone to repair it, everything after he disguises himself as a repairman can make sense. However, this will create several questions, one is whether the identity of the murderer is a real maintenance worker, if it is easy to find, if not, then how to replace the real maintenance worker.

In this way, it is easy to make sense that Tang Hong's small amount of bills should also be checked.

However, it is not yet certain whether the whole process of the case is really like this, and this is only a hypothesis.

Some of the history of the case has some eyebrows, but there are still few clues about the murderer. What is the real purpose of the murderer killing Tang Hong, the detective team is still investigating, but there are waves of unsettled, and when the detective team is still discussing Tang Hong's case, the phone in the office of the Criminal Investigation Bureau rang again!
