At the hideout where the three-man gang was hiding, the criminal police officers from Chiyong City greeted Jiang Yuan one after another.
People are so realistic, especially the police.
When encountering someone who can't do it, everyone will look at him like "I can't do it." But when meeting someone who can really solve the case, everyone's attitude will naturally soften.
The stronger the crime solver and the stronger the ability, the softer everyone will be.
The detachment leader also quickly came out of the room, smiling like an ugly orange. He shook hands with Jiang Yuan from a distance and said: "Expert Jiang, this should be the hiding place of the three criminals. We will try our best to
Maybe the scene can be protected."
"Then let me watch the scene first?" Jiang Yuan said and started to put on gloves.
"Okay, okay," the detachment leader agreed repeatedly.
Liu Jinghui was also pretending to be wearing gloves, leg gloves, headgear and a mask, so-called three sets per mask, and asked, "Has the identity of the criminal been confirmed?"
"It's confirmed. This time, thanks to the clues given by the two of them." The detachment leader readily recognized the help, and then said: "The main culprit is most likely a man with a height of 1.8 meters. His name is Xu Yang. We found him in the room.
The packaging of some items from the Ma family, the remaining ropes, and a few pieces of blood-stained underwear."
"Neither the murder weapon nor the jacket were found?" These two explanations are naturally stronger.
The detachment leader shook his head: "We haven't found anything in the room yet. They should have been disposed of."
"What is the relationship between Xu Yang and Ma Zhongli?"
"It doesn't matter." The detachment leader replied decisively.
At this time, Jiang Yuan, Mu Zhiyang and others also looked over.
The detachment leader spread his hands and said a little embarrassedly: "So I have to thank you for finding the clues about the safe. From the perspective of interpersonal relationships, these three people have not much contact with Ma Zhongli.
If I want to talk about it, it’s Number 2, the knife-wielding man Fan Peng. He is a local, and anyone with a lot of limbs can always contact Ma Zhongli.”
"That should be him." Liu Jinghui guessed the answer directly.
The detachment leader who was introducing the case was stunned and asked: "Why?"
"Because he has the strongest tendency to silence. Among the four people in Ma Zhongli's family, two people had their necks wiped, and the hostess was chopped several times. Of course, it can also be explained that these two people saw his face, or that
I didn’t say anything, but now that there is this kind of interpersonal relationship, Fan Peng’s suspicion will be greatly increased. "
The detachment leader nodded silently. He could actually make the same reasoning, but he didn't dare to be as sure as Liu Jinghui.
Now that we have the facts to solve the case, we can imagine that there must be many unreliable reasoning behind Liu Jinghui's certain reasoning that has been ruled out.
In general, Jiang Yuan and Liu Jinghui have proven their strength. No matter what they do, they will have a halo.
Jiang Yuan took the lead in walking into the trio's den.
This is the second floor of an old residential building. The building has a history of more than 30 years. The outside and inside are still made of pure cement. It is gray and dotted with black stains. I don’t know when it was made.
Something posted in the situation.
The corridors are also wrapped in cement and appear a bit cramped and dark due to the accumulation of various debris.
Jiang Yuan directly asked someone to hold the inspection light and first dealt with the traces on the door.
Upon entering the site, there was only a small house with one bedroom and one living room. As far as the eye could see, everything, including the bed, was dirty and messy.
Not only the kitchen at the entrance, but also the floor leather on the floor are warped everywhere. Needless to say, the rental deposit will definitely not be returned.
Mu Zhiyang and others entered and skillfully turned on the inspection lights, footprint lights, fingerprint lights, etc.
The survey equipment was basically provided by Chiyong City, and their own survey was just waiting in front of them, which was regarded as giving the opportunity of the first round of survey to Jiang Yuan.
This is completely different from the initial treatment.
Jiang Yuan took a rough look at the scene inside, and then started to build a Banqiao while walking, the official name was Quick
Channel Pedal".
Chiyong City uses folding metal pedals, which completely fits the name Banqiao. The metal pedals are not as good as the acrylic pedals, but they are strong and durable, and can be regarded as very middle-class survey supplies.
In fact, by looking at the criminal police equipment in a place, you can easily see the degree of importance attached to the local economy and criminal police system.
For units like Shanghai 803, there is no need to discuss cost-effectiveness. Whatever equipment is good or new is used. If it is not used well, it is no problem to replace it or give it away.
Units like Chiyong City, just like middle-class families, must pay attention to cost-effectiveness in everything, and only purchase necessities as much as possible. Necessities are preferably durable goods that can be used for a longer period of time, saving replacement and maintenance costs.
As for units like Ningtai County, they are the poor people in the criminal police system. Basically, everything is lacking and poor. If you save a little money, you can buy some urgent and necessary things. Even if you know that something is cost-effective, you can still
After looking at the price, I finally chose the cheaper one.
It was only after Jiang Yuan was sold that the economic situation of the Ningtai County Bureau improved.
Therefore, even if Huang Qiangmin wanted to keep Jiang Yuan, he could only send him out to solve the case.
Several trace inspectors from Chiyong City followed Jiang Yuan's footsteps and paid attention to his operations.
Similar to forensic doctor Qiu Xing, in Chiyong City's trace examination, the two main characters can also have level 2.
This is also the result of practice. If a prefecture-level city's trace inspection does not have an LV2 trace inspection, the crime detection rate will be broken down in up to two years.
But if it really doesn’t happen, a few young trace investigators should be smarter and finish each case one after another.
After one or two years of hard work, it is possible to develop a V2.
Of course, it is only possible that someone like Lao Yan from Ningtai County, who has been practicing for a lifetime, is still a strong player in V.
Jiang Yuan walked slowly along the Banqiao, looking at it as he walked. When he saw traces on the side, he was not in a hurry to wipe it off, but first put a yellow sign on it.
Jiang Yuan walked all the way to the innermost part of the room, where the bed was, and then started to formally search for traces.
Most of the trace inspection and scanning traces are illuminated with various lights, and then the traces are scanned.
Only in rare cases will the trace inspectors scan traces inch by inch. For example, when Jiang Yuan did a secondary survey before, he used this method.
Of course, most criminals involved in small cases do not receive this level of treatment.
This time, Jiang Yuan was not prepared to scan so carefully.
The main reason is that the identities of the three criminals have been determined, and the value of their fingerprints and footprints is actually not high. The core now is to find some other clues to help with the subsequent pursuit.
The trace inspectors in Chiyong City also slowly spread out, picking up the traces behind Jiang Yuan and collecting them.
Jiang Yuan saw a lot but did little.
LV4's crime scene investigation, working in this indoor environment, already has excessive firepower.
To fully use the LV4 crime scene investigation, it must be at least the level of the previous door-to-door murder case, that is, an outdoor environment, where people are constantly coming and going, and the scene is destroyed more than once, and then there will be no traces.
Indistinguishable situation.
For example, the three criminals in the murder case were somewhat cautious at the crime scene, but after returning to this temporary settlement, their caution dropped drastically.
In fact, most criminals are like this. Many people will carefully analyze the situation before committing a crime and devise ways and methods to commit the crime. However, after they actually succeed, they suddenly relax and easily expose their flaws.
1937 Those who are able to maintain concentration, maintain high-intensity attention for a long time, have self-control, and emotional stability, and follow the established plan to complete the self-designed work perfectly. Even if they commit crimes, they are usually not so low-level.
Crimes of property infringement.
Without much decoration, Jiang Yuan could even reconstruct the scene without removing most of the traces.
He looked at it for a long time, at least 20 minutes. After finally entering the bathroom, Jiang Yuan slowly squatted down.
"How old are the three criminals?" Jiang Yuan suddenly asked.
"More than 20 years old, No. 1 is the oldest, 28 years old, then 26 and 24 years old."
Liu Jinghui stood watching and asked, "Is age related to traces?"
"The urine in front of the toilet was everywhere."
If it were three young people in their twenties, it would be more than that.
Jiang Yuan pointed around the toilet in the bathroom.
The urine stains were very light, but the distribution area was almost all over the three sides of the front of the toilet. It looked like the urine was scattered when peeing.
The middle-aged Liu Jinghui was very familiar with this scene, and he immediately nodded and said, "It's true, this man has kidney deficiency at the first sight.
The three criminals are young and strong and cannot urinate to such an extent."
Give me a cotton swab. "Jiang Yuan squatted down again, and then began to carefully extract the urine marks around the toilet."
