Chapter 255: Full of Flaws

The next day.

Shunling Township.

Perhaps because it is in the far suburbs of Changyang City, perhaps because the average income is relatively high, or perhaps because the natural environment is relatively good, driving through the slightly chaotic township junction, the core area of Shunling Township is actually somewhat tranquil and beautiful.

The slightly turbid Man-Water River passes through the city from upstream, bringing abundant water vapor and wind.

The arch bridge crossing the river has imitation ancient stone bridges, as well as concrete bridges that can carry heavy-duty vehicles, splitting Shunling Township into two parts.

One part is the continuous, tranquil, and beautiful township life, and the other is the intense, noisy, and chaotic logistics park and industrial zone.

Most young people are active in the factory area, occasionally coming to the old town side to wander around, mainly couples, whether male-female, male-male, or female-female.

Going slightly deeper into the texture of the township, which is the residential and living area, a large number of buildings from the last century come into view.

Shunling Township did not carry out large-scale demolition but adopted the model of building a new district. Today, the expansion of the new district also uses the model of a new new district. The time in the old town area seems to have been fixed.

The government has indeed put in a lot of effort in terms of city appearance. From an outsider's perspective, one can see beautiful exterior walls and streets, which have also attracted some leisure crowds, but the number is not large, and the average age is relatively old.

Seeing Jiang Yuan's gaze sizing up the outsiders, Wang Chuanxing, who is in the same car, sensitively explains: "Three years ago, there weren't this many tourists. It can be said that there were basically no tourists. The outsiders were merchants, drivers, or factory workers. The current farmhouse entertainment was only set up in the last two years, and they all go to the surrounding fishing parks..."

"Was the victim involved in these?" Wei Zhenguo asks: "For example, demolition plans, renting or selling houses, renovating homestays, etc. Have you checked?"

This is asking about economic factors.

In Wei Zhenguo's understanding, the situation the deceased encountered is very similar to the model of a criminal organization. However, to reach the level of homicide, it is either that the interests are huge, or the perpetrator is extremely arrogant, which somewhat does not fit.

Wang Chuanxing also knows what Wei Zhenguo means, so he says: "We asked the people around, and there were no such economic disputes. We haven't heard of any either. The burglary and robbery cases in the logistics park here are mostly small groups at most."

Wan Baoming says more directly: "Because of this case, the groups here have all been screened. Several people have been sent to prison, and the interrogations were very detailed. There were no clues."

"Let's go directly to the scene to see." Jiang Yuan says, urging slightly upon hearing this.

After reviewing and thinking yesterday, he already has some ideas. Regarding the work once done by the special task force where Wang Chuanxing is located, he feels he already understands it well enough.

A case occurring in the provincial capital has one benefit: the various levels responsible for the case have relatively high quality. For example, photography. In Ningtai County, it is a concurrent job for the scene investigator, but in Changyang City, the full-time criminal photographer is very competent, whether in terms of the overall picture or details.

This lays a very good foundation for case assistance.

Like now, if Jiang Yuan wants to use bloodstain analysis or footprints, his main reliance is on these photos.

If the photos are taken well and the scene is captured completely, Jiang Yuan's confidence will be stronger. _o_m

He went to the scene also to compare it with the scenes in the photos.

Wang Chuanxing and Wan Baoming naturally have no objections; both are here to accompany him today.

The car stops at the street entrance, a group of people dives into the alley, and after walking for about ten minutes, they arrive at the crime scene.

The small courtyard where the victim once lived has been completely abandoned.

A large lock hangs in front of the door, grass has grown on the wall, and no one pays any attention to it.

The houses of the neighbors nearby are about the same. Mu Zhiyang ran to find someone to ask, and they all moved away shortly after the incident.

None of them find it strange.

It is not a rare thing for neighbors living right next to the crime scene to be unwilling to continue living in the old house. In big cities, many people may have no choice. Let alone having a haunted house next door, there are plenty of people who live in haunted houses to save hundreds of thousands of dollars.

Houses in townships are not valuable. Buying a new set often only costs tens of thousands or over a hundred thousand. Some people can also move to live with their children.

Wang Chuanxing directly uses hydraulic. (This chapter is not finished!)

Pliers, cuts the lock, and opens the door.

As the door opens, several sheets of yellow paper float out, blown high by the wind.

Mu Zhiyang cannot help but hug his own shoulders.

Creak.

The old house's door looks shaky.

The gray-black wooden door is a bit paint-peeled and a bit deformed, but it no longer looks like it has bloodstains.

"Was the scene cleaned?" Wei Zhenguo looks back and forth once.

Wang Chuanxing says "En" and adds: "We asked them to keep the scene as intact as possible at the time, but it's estimated that too much time has passed."

The special task force's work has basically stopped, and the family members can roughly feel it.

Jiang Yuan takes out his tablet, flips through the photos, and while looking, verifies them with the surrounding environment.

After circling around, Jiang Yuan returns to the door, finds a photo with the corpse, looks left and right, and says: "I want someone to pose for a shot."

"Little Mu, you go." Wei Zhenguo orders his apprentice without any burden.

Mu Zhiyang sighs: "I just washed my police pants last week."

As he speaks, Mu Zhiyang glances at the position in the picture and lies down nimbly.

Jiang Yuan compares it with the photo and helps Mu Zhiyang straighten his posture.

Mu Zhiyang moves on the ground like a worm.

After it is set, Jiang Yuan gets up, takes a photo, and says: "Curl up a little bit, you are taller than the corpse."

Mu Zhiyang then curls up a little.

Jiang Yuan then says to Wei Zhenguo: "Team Leader Wei, stand here, bend over and touch, and see where you can touch Mu Zhiyang."

As soon as Wei Zhenguo sees the position Jiang Yuan points to, he knows it is the position where half a bloody footprint was left that day, and he follows suit, suppressing his curiosity.

Wei Zhenguo is a little over 1.7 meters tall, a standard height. Bending over from the side to reach out, he can just touch Mu Zhiyang's chin position.

"What do you say?" Wei Zhenguo asks as he gets up.

Wang Chuanxing and Wan Baoming also look over curiously.

Jiang Yuan looks at Mu Zhiyang and Wei Zhenguo's positions for a while, but turns to Wan Baoming and says: "For this case, I believe it is not a random crime."

"It can be seen that you have had ideas for a long time. Is there a problem with the footprints?" Wan Baoming had anticipated it. However, he stood on the side of random crime, which was a matter of understanding. At this time, he was just waiting to hear Jiang Yuan's description.

Jiang Yuan nods and says: "From the perspective of bloodstains, this footprint is the most unnecessary."

Jiang Yuan circles the positions of Mu Zhiyang and Wei Zhenguo and says: "The formation of a blood pool takes time. If the perpetrator didn't stab the victim in the chest and leave immediately after pulling the knife, they wouldn't have stepped into a bloody footprint. This is the first point."

"Maybe it was just searching for property." Wang Chuanxing had probably discussed similar topics in the special task force.

"Property carried by an elderly person living alone?" Wei Zhenguo retorts upon hearing this.

"Maybe it was keys, or a watch, a necklace, or a pocket watch and other accessories." Wang Chuanxing has a predetermined answer here, and it is quite reasonable.

Jiang Yuan shakes his head secretly.

Just as Jiang Yuan initially imagined, the bloodstain analysis and footprint identification level of the Changyang City Criminal Police Detachment is about 400 or 500 points. They have a certain analytical and judgment ability, but in the end, they cannot solve the big problems.

And Lv5 bloodstain analysis + Lv3 footprint identification in this era is equivalent to an 800-point performance, purely a crushing level.

If Jiang Yuan were given a current crime scene, he would have a high probability of solving the case in a short time, just like the criminal investigation experts of decades ago did.

Bloodstains + footprints are the standard configuration for technical criminal investigation experts from 40 years ago.

Today, it is about scene investigation + image investigation + fingerprints + DNA. Speaking of which, the case-solving efficiency and combat power of today's criminal investigation personnel are certainly higher, but they cannot help the fact that different cases always have different adaptability.

For some cases, when there are enough clues, no matter which series of experts they are, they have ways to break through and solve the case. This is also the norm for most cases.

But for some cases, one has to pay attention to adaptability.

Like the case in front of us, another hope for a breakthrough should be the forensic expert. But Jiang Yuan has also read the forensic report, and it similarly provides no clues. (This chapter is not finished!)

What clues can be provided.

At this time, Jiang Yuan is like a student who just scored 800 points on a test, waving his hand and saying:

"Regarding what the perpetrator was doing while bending over after stepping into the blood pool, I have another hypothesis."

"I believe they were checking for nasal breath or the carotid artery to determine if the victim was dead."

"Stepping into the blood pool means the perpetrator waited at the scene for a period of time. I believe they waited for at least more than a minute. For a perpetrator, this time must be very valuable. First update@"

"Searching for property doesn't quite fit. Not to mention that the perpetrator could completely use a knife to threaten and take away property. Even if they killed first and then took property, they actually didn't need to wait. Even if the victim had a little resistance ability at this time, so what? The victim was a thin and weak elderly person. After being stabbed, there was no need to wait for them to breathe their last before searching their body. If it was a two-person crime, it would be even easier."

Wang Chuanxing's eyes widen upon hearing this. Although it is not a very strange theory, Jiang Yuan analyzing it to this extent after just one look is still slightly beyond his expectations.

Jiang Yuan cannot help but think of Liu Jinghui at this time. He is making inferences based on bloodstain analysis, but he doesn't know how Liu Jinghui would reason if he received a 400-point evidence report.

"Let's stop here with the speculation on purpose. Let me talk about the footprints themselves." Jiang Yuan flips through his phone and says: "I see you have also found several footprint experts, and the judgments given, let me summarize, range from 40 to 65 years old..."

Jiang Yuan pauses and says: "The footprints at the scene are chaotic, and there is only half a bloody footprint, so there are indeed many variables in the analysis. I tend to think they are older. 55 to 65 years old, or even wider."

This time, without waiting for Wang Chuanxing to express his opinion again, Jiang Yuan adds: "Next, let's talk about bloodstains. In this area, I think it is more important."

Jiang Yuan brushes through several photos, then half-squats in front of the door, and says: "Let's not talk about other parts first. From the photos taken, the most important point is that the spatter pattern here has a blank space..."

Jiang Yuan circles a piece at the door crack. He stands a bit in front and says: "Combined with the forensic autopsy report, I believe the perpetrator was standing at my position at that time, and, the waist and legs here were spattered by blood, which is equivalent to being whipped by a strip. That's why the small blank space at the door crack was formed."

Wang Chuanxing tries hard to look at the pictures on Jiang Yuan's phone and the position of the door crack, but gains nothing.

This belongs to the difficulty of the third sub-question of the second-to-last big problem. A 400 or 500-point level can challenge it, but usually, it takes 600 points to solve it.

This case is still somewhat special. The Changyang City Criminal Police Detachment probably didn't assemble the most suitable investigation team, and it is normal that the bloodstain analysis was not done well.

In today's criminal police detachment, few people are good at bloodstain analysis.

Moreover, there is little blood in this case, and many scene investigations probably didn't think in this direction.

Wan Baoming asks with focused attention: "If the perpetrator's standing position is indeed like this, it means that after the victim opened the door, the perpetrator walked two steps inside. This social distance is a bit close."

Jiang Yuan nods slowly: "Therefore, the perpetrator is likely an acquaintance. And, considering their clothes and shoes were stained with blood, it is very inconvenient to take public transportation. The possibility of living nearby is very high."

A gust of wind blows from behind, giving several people goosebumps.

Wang Chuanxing gives a start and asks: "Then what about the sound of meter reading? If it were a nearby resident, wouldn't the person who saw them recognize them at a glance?"

"No other households had their electricity meters read, which means the victim was likely the first one to be called to open the door. Calculated this way, the perpetrator should have shouted a few times when shouting for meter reading." Jiang Yuan pauses and says: "I cannot explain the witness testimony for the time being, but I believe we should first investigate along the clues of bloodstains and footprints."

Wan Baoming says at this time: "Witness testimony can be put aside for now. These are all neighbors. Before the police arrived, they had already gathered at the scene for a long time. There are many cases of mutual influence or mutual suggestion. Moreover, the witnesses in this case are all elderly, and the case happened during the afternoon nap time..."

Wang Chuanxing is a bit unconvinced, but for a moment, he doesn't know how to retort.

Jiang Yuan says: "Let's not worry about that for now. I suggest listing the (This chapter is not finished!)

nearby residents, and then find out who was not at the scene after the police arrived, and we will visit them."

Wan Baoming cannot help but nod: "The perpetrator has to return to their residence, change and handle the bloody clothes and murder weapon, and maybe even take a shower, so they cannot arrive at the scene in a short time. @Essence/Book Pavilion*First update~~"

"I saw the list of people who gave statements yesterday. Let me look for it." Wang Zhong finally finds something he can do and directly takes out his notebook to operate.

Wang Chuanxing looks at the actions of several people, feeling all kinds of discomfort, and asks in a low voice: "This... what if we visit the perpetrator, what should we do?"

"Then we arrest them." Wei Zhenguo counts the manpower.

To tell the truth, six people arresting one murderer is indeed a bit small, but 4 strong young men in their twenties, plus two middle-aged people, seem not so dangerous to press down on an elderly person who is likely over 60 years old. ===== CHAPTER 256 =====
