Maybe it’s because it’s in the outer suburbs of Changyang City, maybe it’s because the average income is higher, maybe it’s because the natural environment is better, driving through the slightly chaotic junction of towns and villages, the core area of Shunling Township turns out to be a bit peaceful and beautiful
.
The slightly turbid Manshui River passes through the city from the upper reaches, bringing abundant water vapor and wind.
The arch bridges across the river include antique stone bridges and concrete bridges that can accommodate heavy-duty vehicles, splitting Shunling Township into two parts.
Part of it is the continuous tranquility of beautiful rural life, and part of it is the intense hustle and bustle of chaotic logistics parks and industrial areas.
Most of the young people live in the factory area, and occasionally they come to hang out in the old city. They are mainly men and women who are in love.
A little deeper into the fabric of the township, that is, the residential areas and living areas, you will see a large number of buildings from the last century.
Shunling Township did not carry out large-scale demolition, but adopted the model of building new districts. Now, the expansion of new districts also uses the model of new districts. The time of the old city seems to be fixed.
The government has put a lot of effort into improving the appearance of the city. From an outsider's perspective, you can see the beautiful exterior walls and streets, which also attract some leisure crowds, but the number is not large and the average age is relatively older.
.
Seeing Jiang Yuan looking at the outsiders, Wang Chuanxing, who was in the same car, explained sensitively: "Three years ago there were not so many tourists. It can be said that there were basically no tourists. The outsiders were all merchants, drivers, or factory workers.
.The current farmhouses were only built in the past two years, and they all go to the surrounding fishing gardens..."
"Has the victim been involved in any of this?" Wei Zhenguo asked: "For example, demolition plans, renting or selling houses, decorating B&Bs, etc. Have you checked?"
This is about economic factors.
According to Wei Zhenguo's understanding, the situation the deceased encountered was very similar to the model of a mafia society. However, to commit murder to the extent, it was either because the interests were huge or the murderer was extremely arrogant, which was somewhat inconsistent.
Wang Chuanxing also knew what Wei Zhenguo meant, so he said: "After asking people around me, there are no such financial disputes. I have never heard of them. Some people in the logistics park here engage in theft and robbery. At most, they are small groups."
Wan Baoming said more directly: "Because of this case, all the groups here have been screened, several have been imprisoned, and the interrogation has been very careful. There are no clues."
"Go directly to the scene and watch." Jiang Yuan urged him slightly when he heard this.
After yesterday's review and thinking, he already had some ideas. He felt that he already knew almost everything about the past work of Wang Chuanxing's task force.
One advantage of cases that occur in provincial capitals is that all levels responsible for the case are of high quality. For example, in Ningtai County, photographers are part-time investigators, but in Changyang City, full-time criminal photography technicians are
From the overall to the details, the photography is very good.
This lays a good foundation for seeking help in cases.
Like now, if Jiang Yuan wants to use bloodstain analysis or footprints, he mainly relies on these photos.
If the photos are taken well and the whole scene is taken, Jiang Yuan's confidence will be stronger.
He arrived at the scene to compare it with the scene in the photo.
Wang Chuanxing and Wan Baoming are inseparable, and they are both here to keep company today.
…
The car stopped at the street entrance, and a group of people got into the alley and walked for about ten minutes to the crime scene.
The small courtyard where the deceased once lived has been completely abandoned.
A big lock was hung in front of the door, and grass grew on the wall, but no one paid attention to it.
The houses of the previous neighbors were almost the same. Mu Zhiyang went to find someone to ask, but they all moved out not long after the incident.
No one found it strange.
It is not uncommon for neighbors who are close to the crime scene to be unwilling to continue living in the old house. In big cities, many people may have no choice. Not to mention that the house next door is a haunted house. In order to save hundreds of thousands of dollars, they live in a haunted house.
A lot.
Houses in towns and villages are not valuable, so buying a new one often costs tens of thousands or hundreds of thousands. Some people can even move in with their children.
Wang Chuanxing directly used hydraulic pliers to cut the lock and opened the door.
When the door opened, a few pieces of yellow paper floated out, blown by the wind.
Mu Zhiyang couldn't help but hugged his shoulders.
squeak.
The door of the old house is shaking.
The gray-black wooden door has some paint peeling off and is a little deformed, but there is no trace of blood stains.
"Has the scene been cleaned?" Wei Zhenguo looked back and forth.
Wang Chuanxing said "Yes" and added: "We asked them to stay on site as much as possible, but it probably took too long."
The work of the task force has basically stopped, and the family members can probably feel it.
Jiang Yuan took out his tablet computer and pulled out the photos. While looking at them, he verified them with the surrounding environment.
After going around in a circle, Jiang Yuan returned to the door, found a photo with a corpse, looked around, and said, "I want to pose for a photo alone."
"Xiao Mu, come on." Wei Zhenguo ordered his apprentice without any burden at all.
Mu Zhiyang sighed: "I just washed the police pants last week."
As he spoke, Mu Zhiyang glanced at the position on the picture and lay down quickly.
Jiang Yuan compared the photos again and helped Mu Zhiyang correct his posture.
Mu Zhiyang was moving on the ground like an insect.
After the arrangement was completed, Jiang Yuan stood up, took a photo, and then said: "Hold up a little, you are a little taller than the corpse."
Mu Zhiyang then curled up a little.
Jiang Yuan said to Wei Zhenguo again: "Captain Wei, stand here, bend down and touch to see where you can touch Mu Zhiyang."
Wei Zhenguo looked at the location pointed by Jiang Yuan and knew that it was the location where half a bloody footprint had been left that day, so he followed the instructions despite his curiosity.
Wei Zhenguo is just over 1.7 meters tall, of standard height. He bent down and reached out from the side, and he could just touch Mu Zhiyang's chin.
"What do you say?" Wei Zhenguo stood up and asked.
Wang Chuanxing and Wan Baoming also looked over curiously.
Jiang Yuan looked at the positions of Mu Zhiyang and Wei Zhenguo for a while, then looked at Wan Baoming and said, "I don't think this case was a random crime."
"I can see that you have already had an idea. Is there a problem with the footprints?" Wan Baoming had expected it. However, he committed the crime at random, which was a problem of recognition. At this time, he was just waiting to hear Jiang Yuan's description.
Jiang Yuan nodded and said: "Judging from the blood stains, this footprint is the most unnecessary."
Jiang Yuan circled the positions of Mu Zhiyang and Wei Zhenguo with his hands, and said: "It takes time to form a pool of blood. If the murderer didn't stab the victim in the chest, draw the knife and leave, he would not leave bloody footprints.
.This is the first point."
"Maybe I'm just looking for belongings." Wang Chuanxing probably discussed similar topics in the task force.
"Are these belongings carried by an old man who lives alone?" Wei Zhenguo retorted after hearing this.
"Maybe it's a key, or a watch, a necklace, or an accessory such as a pocket watch." Wang Chuanxing has an established answer here, and it makes sense.
Jiang Yuan shook his head secretly.
Just as Jiang Yuan originally imagined, the bloodstain analysis and footprint identification level of the Changyang City Criminal Police Team is only about 400 to 500%. They have a certain ability to analyze and judge, but in the end they are unable to make big problems.
In today's era, LV5 bloodstain analysis + LV3 footprint identification is equivalent to a record of 800 points, a pure defeat.
If Jiang Yuan is given a crime scene, he has a high probability of solving the case in a short time, just like what the criminal investigation masters did decades ago.
Blood stains + footprints were the standard configuration for technical criminal investigation experts 40 years ago.
Nowadays, it is about spot investigation + graphic investigation + fingerprint + DNA. Speaking of which, today's criminal investigators are definitely more efficient and effective in solving crimes, but they cannot handle different cases and always have different adaptability.
In some cases, when there are enough clues, no matter which series the master is, there is a way to break through and solve the case. This is also the norm in most cases.
But in some cases, it is necessary to talk about palatability.
For the case at hand, another hope for a breakthrough should be forensic medicine. But Jiang Yuan has also seen the forensic report, and there are no clues to provide.
At this time, Jiang Yuan was like a student who had just scored 800 points on a question, swiping his hand and saying:
"I have another idea about what the murderer was doing when he stepped into a pool of blood and bent over."
"I think he was trying his nose or carotid artery to determine whether the victim was dead."
"Stepping into a pool of blood means that the murderer waited at the scene for a period of time. I think he waited for at least one minute. For a murderer, this time must be very valuable."
"It is not appropriate to search for property, not to mention that the murderer can use a knife to coerce him to take away the property. Even if he kills first and takes the property later, there is no need to wait. Even if the victim has a little ability to resist at this time, so what. The victim
The person is a thin old man. After being stabbed, there is no need to wait for him to die before he can be searched. It would be easier if two people committed the crime."
Wang Chuanxing's eyes widened when he heard this. Although it was not such a surprising theory, Jiang Yuan's analysis to this extent was still slightly beyond his expectation.
At this time, Jiang Yuan couldn't help but think of Liu Jinghui. He made his inference based on the blood stain analysis, but he didn't know how Liu Jinghui would reason if he got an evidence report with 400 points.
"Let's stop here for the purposeful speculation. Let me talk about the footprints themselves." Jiang Yuan flipped through his phone and said, "I see that you also found several footprint experts and gave you the judgments. Let me summarize, starting from 40
There are people between the ages of 65 and 65..."
Jiang Yuan paused and said: "The footprints at the scene are chaotic, and there are only half bloody footprints. From analysis, there are indeed many variables. I prefer to be older. 55 to 65 years old, or even a little more relaxed."
This time, without waiting for Wang Chuanxing to express his opinion again, Jiang Yuan said again: "Let's talk about the blood stains next. I think this one is more important."
Jiang Yuan quickly found a few photos, then squatted in front of the door and said, "Let's not talk about other parts. Judging from the photos taken, the most important point is that there are gaps in the splash pattern here.
…”
Jiang Yuan circled a space at the crack of the door. He stood a little further in front and said: "Based on the forensic autopsy report, I believe that the murderer was standing where I was at that time, and his waist and legs were spattered with blood.
, which is equivalent to throwing away a strip. That’s why there is a small amount of blank space at the door gap.”
Wang Chuanxing carefully looked at the pictures on Jiang Yuan's phone and the location of the crack in the door, but found nothing.
This is the difficulty level of the third small question, which is the penultimate big question. It can be challenged at a level of 400 to 500 points, but it usually takes 600 points to solve it.
This case is somewhat special. The Changyang City Criminal Police Detachment probably has not assembled the most suitable investigation team. It is normal that the blood stain analysis was not done well.
In today's criminal police force, few people are good at bloodstain analysis.
What's more, the blood stains in this case were relatively small, and many on-site investigators probably did not consider this aspect.
Wan Baoming asked calmly: "If the murderer's position is indeed like this, it means that after the victim opened the door, the murderer took two steps in. This social distance is a bit close."
Jiang Yuan nodded slowly: "So, the murderer is probably an acquaintance. Moreover, considering that his clothes and shoes are stained with blood, it is very inconvenient to take public transportation. There is a high possibility that he lives nearby."
A gust of wind blew from behind, causing several people to get goosebumps.
Wang Chuanxing got excited and asked, "What about the sound of reading the electric meter? If it is a nearby resident, wouldn't anyone who sees him recognize him at a glance?"
"The meters of other houses were not read, which means that the victim was probably the first one to be asked to open the door. Based on this calculation, the murderer probably only shouted a few times when he called for the meter to be read." Jiang Yuan paused and said:
"I can't explain the witness testimony at the moment, but I think we should first follow the clues of blood stains and footprints to investigate."
Wan Baoming said at this time: "You can put aside the witness statements for now. These are all neighbors. Before the police arrived, they had been gathering at the scene for a long time. There were many cases of mutual influence or hints, not to mention the witnesses of this case.
They are all elderly people, and the case happened during nap time..."
Wang Chuanxing was a little unconvinced and didn't know how to refute for a while.
Jiang Yuanze said: "For now, regardless of the number, I suggest that we make a list of nearby residents, and then find out those who are not at the scene after the police arrive, and we can visit them."
Wan Baoming couldn't help but nod: "The murderer has to return to his residence, change and dispose of the bloody clothes, the murder weapon, and maybe take a shower, but he can't go to the scene in a short time."
"I saw the list of people who made the transcript yesterday. I'll look for it." Wang Zhong finally found something he could do, and he took out his notebook and started working on it.
Wang Chuanxing looked at the actions of several people, feeling uncomfortable, and asked in a low voice: "What... what should we do if we interview the murderer?"
"Then let's arrest him." Wei Zhenguo nodded his hands.
To be honest, six people catching a murderer is indeed a bit low, but four strong young men in their twenties, plus two middle-aged men, holding down an old man who is probably in his 60s does not seem that dangerous.
