Chapter 206
Strangers committing crimes are more difficult to detect than acquaintances committing crimes.

The crimes committed by acquaintances can be investigated one by one along the address book, and can be compared based on interpersonal relationships. There are too many accidental factors in the crimes committed by strangers.

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

Just like the case in front of me, logically speaking, it should have been done by the husband of the deceased.

He is the one who has the most reason to kill, and the one who has the most reason to take away the child.But during the time period when the victim died, the husband of the deceased had just finished masturbating and fell asleep patting his belly.

He didn't have to take any responsibility at all, he just killed his cheating wife and didn't need to pay any money - the only problem was that the child was lost, so this man's relationship network was also searched vigorously.

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

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

Back then, the devils came to the village to search for food, but there were still some they couldn't find.Even such a large wounded person can be hidden, and from this, the villagers can be very skilled in hiding things.

And it would be even more difficult if it was a stranger who committed the crime.

Furthermore, there are also places where strangers commit crimes that cannot be explained.

Hou Lejia asked: "The stranger committed the crime, what did he take the child for?"

"I don't know." Jiang Yuan didn't even bother to guess.

There could be many reasons for taking the child away, but the only evidence he got now was blood stains, and the only thing he could rely on was blood stain analysis.

As for why the stranger took the child away?
Maybe it's because he wants to sell.Maybe it's pure perversion.Maybe it's because I happen to be infertile and missing a child.If Liu Jinghui was called over, maybe he could have a more accurate analysis...

Hou Lejia frowned like the skin of a poodle.

Changing the direction of the investigation, not only was the work of the previous two days in vain, but the biggest problem was still worrying that the case would not be solved.

As an old criminal policeman, when Hou Lejia saw such a case, all he could think of was an acquaintance committing the crime.

Either the husband, or the lover, or the husband's relatives, or the lover's wife Xiaosi...

This is still a rural area. Ten years ago, there was no one in the village who was not an acquaintance.

Although there is a factory now, there are several gates between the factory and the village, and each of them is monitored. 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 gate.

Jiang Yuan looked at Hou Le's family's entanglement, shook his head secretly, walked to the door again, and said, "Actually, it can be seen from this that the victim retreated step by step."

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

Jiang Yuan imitated the action and said:

"Looking at the direction of the bloodstains, the murderer's knife may have been around the victim's neck, or it may have been stabbed like this, so the victim stepped back step by step. Look here, there are footprints..."

"If an acquaintance commits the crime, it means that the victim knows the murderer, then the door will be opened if it is opened, and the door will not be opened if it is not opened. Why do you open the door and step back step by step?"

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

Hou Lejia also listened to it, and then turned to look at his team's current survey, and asked, "What do you think? What is the direction of this bloodstain?"

The few surveyors present all followed Jiang Yuan a while ago and worked on the old man's case of scavengers.

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

It's not that they can handle such a difficult case once in their lifetime.But for such a difficult case, the correct detection method and angle may be special and unique, and it is worth being praised for a lifetime.

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

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

The surveyors present, including the normal LV2 level surveyor and Hou Xiaoyong of LV0.6, can only play dumb at this moment.

Bloodstain analysis is something that current surveys should know, but if you say it is a compulsory course for current surveys, it is at the level of required courses in universities—I probably know that there is such a thing, and I know where to find out more information, but if your exam questions are beyond the outline, don't blame me for getting zero marks.

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

Jiang Yuan couldn't say anything, and just three sentences made the head of the Longli County Criminal Police Brigade spend 18 yuan for himself in handling the case.

Therefore, Jiang Yuan added information while watching, saying:

"The murderer's killing process is relatively rough, but he started to use the way of waving, and the movement of scratching is relatively direct. By the way, the murderer used a relatively small dagger, and it didn't seem to be prepared for killing. Or he didn't Have killed people, or have no experience in killing people."

"Looking at the blood on the side of the bedroom, it should be that the crime has escalated again. The murderer has started to use stabbing methods, but at this time, his actions are rather hesitant. Look at the blood here... you can see that the murderer has instead At this time, the control of the victim is relaxed, giving the victim the opportunity to move and escape."

"This is also more like a crime committed by a stranger than an acquaintance. From my understanding, the murderer mainly intimidated the victim at the beginning, and it was a very direct and harmful threat. In the end, he was about to kill, but he became hesitant. Come to think of it...the victim's character should be a hotter, fiercer kind?"

Hou Lejia is still immersed in the scene described by Jiang Yuan. He is an old criminal policeman, and he can make up a lot of pictures by himself.

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

"Cough cough." Forensic doctor Ye Ma Daha returned to Ma Daha, who was still sensible, interrupted Hou Xiaoyong, and said: "The deceased Wang Huizhi, a local, is 28 years old this year. He is 165 in height and weighs 70 kg. He has a strong physique. He is old and often clashes with the villagers, especially after giving birth to a child, and has had some aggressive behaviors."

"Overreaction?"

"Well, she threw the child's diapers into the uncle's house, and she also threw the shit bag at the neighbor's house next door. She said it belonged to the child, and the neighbor suspected it was hers. The electricity in the village often tripped, and several neighbors had a lot of trouble because of it. Complaints... Wang Huizhi can take advantage of most of the conflicts..."

Forensic Ye explained Wang Huizhi's shrew character in a disguised form, and then said: "It is also because of Wang Huizhi's character and this series of past events that we believe that the probability of committing crimes by acquaintances in the village is relatively high."

"If it wasn't from my family, would Heizi be able to smell it?" Jiang Yuan suddenly thought that he was sold at the price of a dog.

If it is an acquaintance in the village, this level of blood will easily leave a smell, and it will not be cleaned by ordinary bathing.

Hou Lejia said in a deep voice: "Heizi came two days ago, the village sniffed, and the factory also sniffed, but nothing came of it."

"If their family members committed the crime, the smell might be confused." Forensic Ye said, and then said: "Of course, the cannery also affects the sense of smell of sunspots."

"I think some people can be assigned to investigate the criminals who have stolen theft." Jiang Yuan didn't want to directly propose a detection plan, after all, he was in another county.

But Hou Lejia has been hesitant, which makes Jiang Yuan feel a little unhappy.

If only the former criminals are being investigated, there is no need to turn all the staff around. It is more than enough to transfer the manpower of a squadron.

Ordinary theft, or burglary, I am afraid that even one-third of the squadron will not be assigned.

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

As expected, Hou Lejia was a little poked into his mind, but he still hesitated: "Are you only investigating criminals?"

"The murderer didn't leave any skin flakes or hair. He is a very professional burglar, and he has a high probability of being caught." Jiang Yuan is already very experienced in catching thieves.

Most of the thieves are not highly educated.In other words, they seldom learn the knowledge of being a thief by reading books, newspapers or videos.Most of the thieves are educated by social colleges and prison universities, and they are self-improved through repeated punishments.

It can be said that if a thief has never been caught, it is difficult for him to understand everything, he doesn't understand, let alone care.

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

"It doesn't have to be a local, but it may be a fugitive." Jiang Yuan then thought of the cases he had worked on in the past two days, and said: "You can check the surrounding burglary cases to see if there is any surveillance and footprints. Or other evidence brought over, the thief did not make a case.”
