Chapter 205: Division

It is more difficult to detect a crime committed by a stranger than one committed by an acquaintance.

For a crime committed by an acquaintance, one can check the contacts one by one and compare the interpersonal relationships. However, there are too many unexpected factors for a crime committed by a stranger.

After being a police officer for a long time, you will know that speculating on a person's behavior is actually a very thankless task. And it is also very difficult for normal people to predict the behavior of criminals.

For example, in the case in front of us, it is reasonable to say that it should be the husband of the deceased who did it.

He has the most reason to kill and take the child away. But during the time period when the victim died, the husband of the deceased had just finished eating skewers and was sleeping with his belly patted.

He did not have to bear any responsibility at all. His cheating wife died, and he did not have to share the money - the only problem was that the child was missing, so the man's network of relationships was also investigated vigorously.

Including the man's parents and brothers, they are all the focus of the police screening.

Unfortunately, there is no clue at all. However, it is not very certain to say that this proves that the man's family is innocent.

When the Japanese came to the village to search for food, there were still some that they couldn't find. Even such a big wounded person could be hidden. From this, it can be inferred that the villagers' skills in hiding things can be very advanced.

If it was a stranger who committed the crime, it would be even more difficult.

Moreover, there are also things that cannot be explained when a stranger commits a crime.

Hou Lejia asked: "If a stranger committed the crime, why did he take the child away?"

"I don't know." Jiang Yuan was too lazy to even guess.

There could be many reasons for taking the child away, but the only evidence he had now was bloodstains, and the only thing he could rely on was bloodstain analysis.

As for why the stranger took the child away?

Maybe he wanted to sell it. Maybe he was a pure pervert. Maybe he was infertile and needed a child. If Liu Jinghui was called over, maybe there would be a more accurate analysis...

Hou Lejia's brows were furrowed like the skin of a happy dog.

The direction of the investigation was changed. Not only did the previous two days of work go in vain, but the biggest problem was that he was worried that the case could not be solved.

As an old criminal policeman, when Hou Lejia saw such a case, he would think that it was an acquaintance who committed the crime.

It was either the husband, the lover, the husband's relative, or the lover's wife, the mistress...

This is still a rural area. Ten years ago, you couldn't find a person in the whole village who was not an acquaintance.

Although there are factories now, there are several gates between the factory and the village, and each is monitored by surveillance. Although it is not very safe, the main reason is the same. There is no motive, and the victim has no reason to open the door.

Jiang Yuan looked at Hou Lejia's entanglement, shook his head secretly, walked to the door again, and said: "In fact, from here we can see that the victim retreated step by step."

"What?" Hou Lejia was still weighing the pros and cons, and his thoughts were pulled over by Jiang Yuan again.

Jiang Yuan simulated the action and said:

"Looking at the direction of the bloodstains, the murderer's knife may have been on the victim's neck, or he may have stabbed it repeatedly, so the victim retreated step by step. Look here, there are footprints..."

"If it was an acquaintance who committed the crime, it means that the victim knew the murderer, so if he opened the door, he would open the door, otherwise he would not open the door. Why did he retreat step by step after opening the door?"

"So I think the victim probably heard some noise in the middle of the night, and then took the initiative to open the door to see, but was subdued and eventually killed."

Hou Lejia also listened to it, and then turned to look at the on-site investigation of his team and asked: "What do you think? The direction of this bloodstain?"

The several on-site investigators present had all worked with Jiang Yuan on the case of the scavenger old man a while ago.

For ordinary criminal police, this kind of case is done once and remembered for a lifetime.

It's not that they can only do this difficult case once in their lifetime. But for such a difficult case, the correct detection method and angle may be special, unique, and worth bragging about for a lifetime.

Just like bloodstain analysis, 30 years ago, there were still many application scenarios. But in today's environment, the situation is different.

Jiang Yuan's bloodstain analysis is so powerful that the case of the old man who picked up garbage, which was almost impossible to solve directly, was solved in a short time.

The investigators present, including the normal LV2 level investigators and Hou Xiaoyong at level 6, can only play dumb at this moment.

Bloodstain analysis is something that investigators should know, but if you say it is a compulsory course for investigators, it is the level of a compulsory course in college-I roughly know that there is such a thing, and I also know where to find more information, but if your test questions are beyond the scope, don't blame me for getting zero points.

Jiang Yuan casually recreated the scene, which was based on the LV5 level. Hou Lejia made the investigators in Longli County "feel", and everyone felt that they didn't want to "feel".

Jiang Yuan couldn't say that just three sentences made the captain of the Longli County Criminal Police spend 180,000 yuan on his case.

Therefore, Jiang Yuan added information while reading, saying:

"The murderer's killing process was rough, but he started to use a waving method, and the scratching action was relatively direct. By the way, the murderer used a relatively small dagger, and it didn't seem to be prepared for killing. Maybe he has never killed anyone, or has no experience in cutting people."

"Look at the bloodstains in the bedroom. The crime should have escalated again. The murderer began to stab, but at this time, his movements were rather hesitant. Look at the blood here... It can be seen that the murderer relaxed his control over the victim at this time, giving the victim a chance to move and escape."

"This is more like a stranger committing the crime, not an acquaintance. From my understanding, the murderer initially threatened the victim, and it was a very direct and harmful threat. In the end, when he was about to kill, he became hesitant... The victim's personality should be more hot-tempered and fierce?"

Hou Lejia was still immersed in the scene described by Jiang Yuan. He was an old criminal policeman and could imagine many scenes in his mind.

Hou Xiaoyong said naively: "I heard from the villagers that the victim should be a fierce woman..."

"Ahem." Although forensic doctor Ye was careless, he was sensible. He interrupted Hou Xiaoyong and said: "The deceased, Wang Huizhi, was a local, 28 years old this year. She was 165 cm tall, weighed 70 kg, was strong, spoke and acted in a tough manner, had a bad temper, and often clashed with villagers. Especially after giving birth, she had some radical behaviors."

"Extreme behaviors?"

"Well, she threw the child's diapers into her uncle's house and gave them to the separated A bag of feces was thrown at the neighbor's house. She said it was from a child, but the neighbor suspected it was hers. The electricity in the village often tripped, and several neighbors had many complaints... In most conflicts, Wang Huizhi was the one who was more likely to take advantage..."

Forensic Doctor Ye explained Wang Huizhi's fierce character in a disguised way, and then said: "It is also because of Wang Huizhi's character and this series of past events that we think the probability of the crime being committed by an acquaintance in the village is higher."

"If it is not a family member, would Heizi be able to smell it?" Jiang Yuan suddenly remembered that he was sold at the price of a dog.

If it was an acquaintance in the village, this level of blood would easily leave a smell, and ordinary bathing would not be able to clean it up.

Hou Lejia said in a deep voice: "Heizi came here two days ago. We sniffed the village and the factory, but there was no result."

"If it was a family member who committed the crime, the smell might be confused." Forensic Doctor Ye said, and then said: "Of course, the canning factory also affects Heizi's sense of smell."

"I think we can allocate some manpower to investigate the criminals with a history of theft." Jiang Yuan didn't want to directly propose a solution to the case, after all, it was in another county.

But Hou Lejia was hesitant all the time, which made Jiang Yuan feel a little unhappy.

If we only investigate criminals with a history of theft, there is no need to turn all the staff around. It would be more than enough to transfer the staff of a squadron.

For ordinary theft cases or burglary, I am afraid that even one-third of the squadron will not be allocated.

For a current murder case, the diversion of the staff of a squadron is really nothing.

Hou Lejia was indeed a little bit touched, but he was still a little hesitant: "Only check criminals with previous convictions?"

"The murderer didn't leave any dandruff or hair. This is a very professional burglar. It is very likely that he has been caught before." Jiang Yuan is already very experienced in catching thieves.

Most thieves have a low level of education. In other words, they rarely learn the knowledge of being a thief through reading books, newspapers or videos. Most thieves are educated by social colleges and prison universities, and they are self-improving through repeated imprisonment.

It can be said that if a thief has not been caught, it is difficult for him to be comprehensive, he does not understand, and he does not care.

"What about the scope?" Hou Lejia asked: "Mainly around San'an Village?"

"Not necessarily a local, there may be a vagrant criminal." Jiang Yuan then thought of the case he had done in the past two days, and said: "You can check the surrounding burglary cases to see if there is any surveillance, footprints, or other evidence. The thief has not done a case."
