Chapter 205: Divide people
Crimes committed by strangers are more difficult to detect than crimes committed by acquaintances.
Acquaintances committing crimes can be investigated one by one along the address book, and comparisons can be made based on interpersonal relationships. There are too many unexpected factors for strangers committing crimes.
After working as a police officer for a long time, you will know that guessing a person's behavior is actually a very thankless task. It is also very difficult for normal people to predict the behavior of criminals.
For example, in the case at hand, logically speaking, it should be the deceased's husband who did it.
He has the most reason to kill people and take away children. But during the time when the victim died, the husband of the deceased had just finished masturbating and was sleeping with his belly patted.
He didn't have to take any responsibility at all. He killed his cheating wife and didn't have to pay for it. The only problem was that the child was lost. Therefore, this man's network was also vigorously investigated.
Including the man's parents and brothers, they are the focus of police screening.
Unfortunately, there are no clues at all. However, it is not certain that this proves that the man’s family is innocent.
When the Japanese came to the village to search for food, they still couldn't find it. Even such a large wounded person can be hidden. From this, it follows that the fellow's hiding skills can be very superb.
And if it were a stranger who committed the crime, it would be even more difficult.
Furthermore, there are also things that cannot be explained when strangers commit crimes.
The Hou Le family asked: "A stranger committed a crime. What did he do with the child?"
"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 had now was blood stains, and the only thing he could rely on was blood stain analysis.
As for why strangers took away children?
Maybe because he wanted to sell. Maybe it's pure perversion. Maybe he just happens to be infertile and lacks a child. If Liu Jinghui is called over, a more accurate analysis may be possible...
Hou Lejia's brows were furrowed like a pug's skin.
After changing the direction of the investigation, not only were the previous two days of work in vain, but the biggest problem was the worry that the case would not be solved.
As an old criminal policeman, when Hou Lejia saw a case like this, what he thought about was that an acquaintance committed the crime.
Either the husband, or the lover, or the husband's relative, or the lover's wife, Xiaosi...
This was 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 door.
Jiang Yuan looked at Hou Le's family's struggle, shook his head secretly, walked to the door again, and said: "Actually, it can be seen from here that the victim retreated step by step."
"What?" The Hou Le family was still weighing the pros and cons, but their thoughts were pulled away by Jiang Yuan again.
Jiang Yuan simulated the movements and said:
"Looking at the direction of the blood stain, the murderer's knife may have been placed on the victim's neck, or he may have stabbed it repeatedly, so the victim stepped back step by step. Look here, there are even footprints..."
"If an acquaintance commits the crime, it means that the victim knows the murderer, so if he opens the door, he will open the door, and if he doesn't open the door, he will not open the door. Why does he retreat step by step when he opens the door?"
"So I think the victim probably heard something in the middle of the night and took the initiative to open the door to see. Instead, he was overpowered and eventually killed."
The Hou Le family also listened, and then turned to look at their team's current survey and asked, "What do you think? What's the direction of this blood stain?"
Several of the investigators present had followed Jiang Yuan a while ago and worked on the old man's case of scavenging.
For ordinary criminal police, this kind of case is something that will be remembered for a lifetime.
It's not that they can do a case of this difficulty once in their lifetime. But for such a difficult case, the correct detection method and angle may be special, unique, and worthy of being praised for a lifetime.
Just like blood stain 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 was so powerful that the case of the scavenger old man, which was originally almost impossible to solve directly, was solved in a short time.
The surveyors present, including the normal LV2 surveyor and Hou Xiaoyong at 6, could only pretend to be stupid at this moment.
Bloodstain analysis is something that current investigators should know, but if you say it is a required course for current investigators, that is at the level of a required university course - I roughly know that there is such a thing, and I also know where to find out more. information, but if your exam questions are beyond the syllabus, don’t blame me for getting a zero score.
Jiang Yuan casually recreated the scene, which was based on the level of LV5. Hou Lejia made the surveyors in Longli County "feel", but no one wanted to "feel".
Jiang Yuan couldn't say that he would let the captain of the Longli County Criminal Police Brigade spend 180,000 yuan on the case for him in just three sentences.
Therefore, Jiang Yuan added information while reading and said:
"The murderer's killing process was rough, but he started to use the swing 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. Or he didn't Have killed people before, or have no experience in slashing people.”
"Looking at the blood stains here in the bedroom, it should be that the crime escalated again. The murderer started to use stabbing methods. But at this time, his movements were more hesitant. You can see the blood here... you can see that the murderer started to stab. At this time, the control on the victim was relaxed and the victim was given the opportunity to move and escape.”
"This is more like a crime committed by a stranger than a crime committed by 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, when he wanted to kill, he became hesitant. Come on...the victim's personality should be more fiery and fierce?"
Hou Lejia is still immersed in the scene described by Jiang Yuan. He is an old detective and can imagine many scenes in his mind.
Hou Xiaoyong said naively: "I heard from the villagers that the victim should be a shrew..."
"Ahem." Ye Madaha, the medical examiner who returned to Madaha, was still sensible. He interrupted Hou Xiaoyong and said: "The deceased Wang Huizhi, a local, was 28 years old this year. He was 165cm tall, weighed 70kg, had a strong physique, was tough in words and deeds, and had a temper. When I was older, I often had conflicts with the villagers, especially after giving birth to a child, and I had some extreme behaviors."
"Overreaction?"
"Well, she once threw the child's diaper into her uncle's house, and also threw a poop bag into the neighbor's house next door. She said it belonged to the child, and the neighbor suspected that it belonged to her. The electricity in the village often tripped, and several neighbors had a lot of trouble because of it. Complaints... In most conflicts, Wang Huizhi is able to take advantage..."
Forensic doctor Ye explained Wang Huizhi's shrewish character in disguise, and then added: "It is also because of Wang Huizhi's character and this series of past events that we believe that the probability of an acquaintance in the village committing the crime is relatively high."
"If he is not one of his own family, can Heizi smell it out?" Jiang Yuan suddenly thought that he was sold at a dog price.
If it was an acquaintance in the village, bloodstains of this level would easily leave a smell, and ordinary bathing would not be able to clean them.
Hou Lejia said in a deep voice: "Heizi has been here two days ago. We have sniffed the village and the factory, but there are no results."
"If someone in their family committed the crime, the smell might be confused." Forensic Doctor Ye said, "Of course, the cannery also affects Heizi's sense of smell."
"I think we can allocate some people to check for criminals who have committed theft." Jiang Yuan originally 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 we only investigate ex-convicts, there is no need to divert all personnel, and it will be more than enough to transfer the manpower of one squadron.
An ordinary theft or burglary might not even cover a third of the squadron.
For a murder case, the diversion of manpower in a squadron is really nothing.
Hou Lejia was indeed a little pricked, but he still hesitated: "Are we only looking for ex-convicts?"
"The murderer didn't leave any dandruff or hair behind. He is a very professional burglar and has a high probability of being caught." Jiang Yuan is already very experienced in catching thieves.
Most thieves are not highly educated. In other words, they are less likely to learn the knowledge of being a thief by reading books, newspapers or videos. Most thieves are educated in social colleges and prison universities, and they have perfected themselves through being imprisoned again and again.
It can be said that if a thief has never been caught, it will be difficult for him to cover everything. He will not understand, let alone care.
"What about the scope?" Hou Lejia asked: "Mainly around San'an Village?"
"It may not necessarily be a local, it may be a fugitive." Jiang Yuan then thought of the cases he had done in the past two days and said: "You can check the surrounding burglary cases to see if there is surveillance and if there are any footprints. Or bring other evidence, and the thief hasn’t done a single case.”
