When he first started raising alpacas, Ma Tianming did not build a hut for the alpacas, and the two alpacas had fun in the yard.

But the good times didn't last long, and the two alpacas didn't know how to do it, so they ran into the neighbor's house. The neighbor is also a rich man and has a Tibetan mastiff.

The Tibetan mastiff, which has a particularly strong sense of territorial protection, immediately tore up frantically in the face of uninvited guests. The adult Tibetan mastiff is so large and destructive that the two alpacas simply can't resist it. In order to protect the female alpaca, the male grass mud horse desperately dragged the Tibetan mastiff,

The ending was quite tragic, the ram camel unfortunately died, and the Tibetan mastiff who saw the blood madness could only be euthanized. Pet dogs are not able to see blood, once they see blood, the wildness in the body will be stimulated, which is a big threat to the owner.

The two families have equal financial resources, and if they fight each other, they will fight each other, and they both want an explanation. In the end, although it is over, the grudge is next.

It's no wonder that the neighbors spoke ill of each other, obviously Ma Tianming didn't take good care of the alpaca, and the Tibetan mastiff was also a disaster.

Alpacas are social animals and cannot live alone, otherwise they will become depressed and end up depressed. The brown ram llama that came later was bought by Ma Tianming again.

Before traveling around, I thought that the two alpacas would not be separated, but at this time I felt a little embarrassed.

Where is true love, isn't it lonely and cold, and you need someone to accompany you.

The neighbors didn't have anything good to say about Ma Tianming, but Song Guyan still got the information she wanted: Ma Tianming had indeed not appeared for many days.

Zhou You unconsciously snorted, and there was a faint smell that made him very uncomfortable. At first, he thought it was the smell of grass and mud horses defecating in the open, but he noticed that when the alpaca was transported, there was a fixed and convenient place, and it did not smell, so he reacted that the smell should be emitted from another place.

"Wang~Wang~"

Song Guyan looked at the soybean milk powder strangely, what is it called?

"Did you find anything?"

Zhou You nodded hurriedly and gestured to the villa.

The closer you get to the house, the uglier it gets, and it should emanate from the inside of the villa. This kind of smell, Zhou You seems to be familiar with it, the last time was in the forensic laboratory of the Criminal Police Brigade, it was the smell of the fermented corpse.

Song Guyan knew that soybean milk powder would not call for no reason, and he was far away from the house, so he had no intention of approaching at all. This shows that soy milk powder should know what is in the house, which is something he particularly hates.

"Officer Song, you can't enter the room without the owner's consent!" said the security guard dutifully.

Opening the door is actually a bit of a violation of property management regulations, but it can be explained by alpacas. But if you force yourself into the room, if the security guard doesn't do anything, you will definitely be complained.

After taking a few steps forward, Song Guyan's face turned cold.

"The owner probably couldn't agree to it. ”

The security guard's face was clouded, and he didn't hear what this officer meant.

"Bang-" Song Guyan kicked it, and the wooden door of the villa was immediately kicked and broken.

The security guard's face turned pale with fright, and he was just about to go crazy, when a foul smell came to his nostrils, and he almost didn't catch his breath.

Song Guyan was also a little unbearable, so he quickly covered his mouth and nose, remembering that the soybean milk powder was defenseless, and wanted to remind him to pay attention, but he didn't see Labrador.

Looking back, the Labrador is 108,000 miles away from the villa, and I don't know when it ran away.

The sense of smell of dogs is already sharper than that of humans, and even Song Guyan can't stand the stench, which has to be magnified dozens of times when traveling here. Zhou You really didn't dare to approach, for fear that he would be smoked to death.

Song Guyan covered his mouth and nose and went into the house to check the situation, and soon came out to catch his breath and make a phone call to the criminal police brigade.

Before he returned to the unit, he encountered a case.

The colleague arrived very quickly and stopped the area around the villa with a rope.

The corpses stink like this, it must have been several days, and if the temperature is not particularly high, the time of death may have to be extended. In this case, there are very few clues left on the scene, and if there are unrelated people walking around, the few clues left may be destroyed.

Two forensic doctors came, and the young male forensic doctor, even with a thick mask, couldn't stay in the house for long, and soon ran out and vomited. The familiar iceberg female forensic doctor stayed for a long time, but her face was a little pale when she came out.

After all, they are the same kind, and they are always a little panicked when they see such a tragic scene.

Zhou You thinks that he can eat while watching "The Walking Dead", and he can adapt to watching too many bloody scenes. But once in reality, I can't stand it at all. probably knows that no matter how heavy the TV series is, it's just a prop, not true. Under the psychological suggestion, there were not many adverse reactions.

But the scene inside the villa was real, and the stench that soaked his soul made him not want to go in and see it at all.

Song Guyan noticed that Xi Yao had been looking at her for a long time, and couldn't help frowning and asking.

Xi Yao said curiously: "How do I feel that you are Conan possessed, there will be cases wherever you go?"

Song Guyan couldn't help but roll his eyes: "Can I understand that he is praising me?"

Xi Yao nodded very seriously: "You are indeed as powerful as Conan, and you can solve the case if you encounter it!"

Song Guyan knew Xi Yao very well, her IQ was sometimes online, and sometimes she was decisively offline, so she couldn't bear it.

Zhou You, who was in the distance, heard their conversation and smiled.

Where is the shovel officer with Conan's bonus, obviously because Labrador is the protagonist, so something happens every time, otherwise how can the plot continue.

"The time of death is about 5 to 7 days, it is highly corrupt, and it has formed a giant view. The female forensic doctor said coldly.

After the end of life, the putrefactive bacteria that had been parasitic in the human body during the state of life lost the control of the body's immune system and multiplied wildly. These staggering amounts of spoilage bacteria can produce large amounts of putrefactive gases that are dirty green. These putrefactive gases filled the human body, and the corpse was swollen and swelled into a giant, making it difficult to recognize its former appearance.

"The body was hanging, there was a heavy rope mark on the neck, and no useful clues were found at the scene for the time being. "We also need to bring the body back to the lab for a detailed examination." ”

"Is there a possibility of suicide?" Song Guyan asked.

The female forensic doctor hesitated for a moment: "It is not ruled out, there will be results after identification." ”

"I'm sorry for you. ”

has a specialization in the art industry, and Song Guyan only knows a little about forensic identification, which is not as good as the female forensic profession.

The situation seen at the scene is in line with the characteristics of Ma Tianming's suicide, but it is not excluded that the scene was artificially created. The cause of death by hanging is not what we usually think of as suffocation, although during the hanging, the airway does become blocked, leaving the victim feeling "out of breath". But in fact, the real cause of death by hanging suicide is a blockage of blood vessels in the neck, which prevents the brain from obtaining oxygen and blood supply from the lungs, resulting in cerebral ischemia.

The biggest difference between suicide and homicide is "how to strangle", that is, the characteristics of the cord groove formed by the rope and the neck are different.

In the case of suicide, the position of the knot is usually divided into anterior, posterior, and lateral positions without interference from others. The scars will also change depending on the hanging posture, but in general, the scars will be in a "V" shape: the lowest part is the deepest, rising to the sides and gradually shallower, and finally disappearing, which is the biggest difference between suicide and homicide. On the body of a strangled victim, the strangulation marks are usually in a full circle, uninterrupted, and there are often traces of knots. Compared with the V-shaped scars of the suicide person, the rope loop of the strangled person is shallower, more complete, and more detailed.

On highly decomposed corpses, it is difficult to distinguish this distinction with the naked eye, and the details of the wounds can only be seen with the help of laboratory equipment.

Before the results of the laboratory, Ma Tianming's case was temporarily solved according to murder. Song Guyan asked Xi Yao to go to the property to retrieve the surveillance video, and he returned to the scene to find out if there was anything missing.

Even if the corpse was taken away, Zhou You still felt the strong stench, and he didn't mean to get close to the villa at all. It's just a psychological shadow, Zhou You feels that he has no appetite to eat at least a week.

Zhou You had to complain about Song Guyan again, can you take care of Labrador's feelings when solving the case, it is really too cruel, and I can't bear it at all!

The whole villa smelled, and Song Guyan put on several layers of masks, still feeling dizzy. But in order to solve the case, I can only endure it. She can understand soy milk powder, after all, police dogs are not trained to this extent, and it is normal that they can't stand it.

Moreover, the criminal detection dog is mainly tracking and looking for clues, and the people have been dead for several days, and the clues that the police dog can find are limited.

When Song Guyan came out again, there were a lot of beads of sweat on his face, and he was carrying a few plastic bags in his hands.

You You took a look at it, and it seemed to be hairpins and a few long hairs.

According to the introduction of the previous security guard, Ma Tianming's wife and children settled abroad, and it was impossible to live in the villa. Then these hairpins and hair should be Ma Tianming's concubine's.

Unprovoked killings exist, but they are relatively rare. In ordinary cases, if you want to solve the case, you have to overturn the murderer's motive for committing the crime. Psychologically, human behavior is governed by motivation, and motivation is caused by need, and motivation cannot be generated without need. However, not all needs can be motivated, only when they need to point to a certain goal and show the possibility of achieving the goal, can they form a motivation and have a driving force for behavior. In other words, there is a need to arise, and there must be a trigger condition.

To put it simply, it is to narrow the scope of suspicion by assuming several motives for killing, combined with the victim's social relationships, to see if it can be logical. The most common motives are love killing, financial killing, and vendetta killing, and there will be more than one suspect in the corresponding.

"You...... That's how you handle the case! I'm ...... I'm at odds with him, but I'm not going to kill him!"

"Sir, we're just asking for a routine question, not suspicious of you!" the police explained.

Song Guyan walked over and patted the policeman's shoulder. The neighbor is only suspicious, not the murderer, so there is no need to ask so urgently. Especially when the other party is emotionally unstable, questioning requires some skill.

Ma Tianming's neighbors are also worth a lot of money, but the traditional concept in China is that business does not fight with officials, and it is still a violent structure such as the police. Not to mention anything else, if the police check a few times, the business may be yellow. His beloved Tibetan mastiff went crazy, he naturally hated Ma Tianming who was not good at taking care of him, but he killed him for this, and the neighbors didn't have this list.

Maybe Song Guyan is a policewoman, she came to ask, and the neighbor's mood was much better, and she also said a lot about the situation.

"Don't look at him in his forties, there are several female college students in his custody!"

"His wife divorced him because of this, but there are few who come here often, and I don't know who it is. ”

"Five days ago, I don't have any specific impressions, it looks like I drove back, right?"

Song Guyan asked if there was anything unusual about the time of the crime, but the neighbor didn't remember much.

Xi Yao, who went to adjust the monitoring, also returned, and the probes at each intersection in the community were intact, which meant that the video would be complete.

Song Guyan breathed a sigh of relief, what he was most afraid of was that when he was investigating the case, he would encounter situations such as damage to the probe and loss of video. Without monitoring, you have to spend a lot of energy to visit and find out, which is a waste of time.

After sweeping the scene, Song Guyan was ready to go to the team.

I'm finally able to get out of this hellish place!

Zhou Yu quickly slipped into the car. No matter how far he went, he always felt that the smell was like a shadow, probably a psychological shadow. It's a pity that he missed one thing, the body has been pulled back to the forensic laboratory, even if it is in a bag, but there is still a smell coming out.

As soon as he stepped into the building of the brigade, Zhou You smelled this stench. Of course, the smell is very light, but it is infinitely amplified when traveling around.

That's not all!

Huddle in the innermost part of the office, by the window, and let the fresh air blow the stench away.

For the time being, the laboratory can only estimate that the time of death is about 5-7 days, so there are a lot of videos that need to be watched, and the technical department can't give an answer in the first time.

As for the forensic lab, there is also some trouble. The degree of decomposition of corpses is very high, and if you want to restore the wound and identify the wound, it will not take time to solve it, and you need sufficient technical support. The female forensic doctor of the iceberg has an arrogant personality, but she also has to admit the gap in technology, and with the existing technology in the laboratory, it is very difficult to restore the highly corrupted wound.

Forensic laboratories tend to be used, and they are certainly not as technically as good as those of scientific research institutions that specialize in academic research. Fortunately, the laboratory has cooperated with Hucheng University, and some parts that need to be restored have been transmitted to them remotely, hoping that more high-end technologies can be processed.

The investigation of the case is based on sufficient clues, and it is speculated that there is no substitute for conclusive evidence.
