"Team Jiang."

"Expert Jiang is here."

At the den where the gang of three were hiding, the criminal policemen from Chiyong City who met 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 with "no way", but when encountering someone who can really solve the case, everyone's attitude will naturally soften.

The stronger the case-solving and the stronger the ability, the softer everyone is.

The detachment leader also quickly came out of the room, smiling like an ugly orange, and shook hands with Jiang Yuan from a distance, saying: "Expert Jiang, this should be the hiding place of the three criminals. Maybe protect the scene.”

"Then I'll watch the scene first?" Jiang Yuan said and began to put on gloves.

"Okay, okay." The detachment leader agreed repeatedly.

Liu Jinghui was also pretending to be wearing gloves, foot covers, headgear and a mask, the so-called three sets and one mask, and asked, "Has the identity of the perpetrator been confirmed?"

"It's confirmed. Thanks to the clues given by the two of you this time." 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 Ma in the room." The packing of some items at home, the leftover rope, and some bloody underwear.”

"We didn't find the murder weapon or the jacket?" These two things are naturally more powerful.

The detachment leader shook his head: "I haven't found it in the room yet, so it should be disposed of."

"What is the relationship between this Xu Yang and Ma Zhongli?"

"It's okay." The detachment leader replied decisively.

Now, 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 the clues to the safe. These three people, in terms of interpersonal relationship, have not had much contact with Ma Zhongli.

If you want to talk about number two, it is Fan Peng, the man with the knife. He is a local, and he can always contact Ma Zhongli if he turns around. "

"That should be him." Liu Jinghui directly guessed the answer.

The detachment leader who was introducing the case was taken aback for a moment, and asked, "Why?"

"Because he has the strongest tendency to silence. Among the four members of Ma Zhongli's family, two of them had their necks wiped, and the mistress was hacked several times. Of course, it can also be explained that these two people saw his face, or that What did you say, but now with this level of interpersonal relationship, the suspicion of Fan Peng 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 there are facts to solve the case, it is conceivable that behind Liu Jinghui's definite reasoning, there must be many unreliable reasoning that have been ruled out.

In general, Jiang Yuan and Liu Jinghui have already proved their strength, and whatever they do, they will have a halo.

Jiang Yuan walked into the den of the three of them first.

This is the second floor of an old residential building.The building has a history of more than 30 years, and the outside and inside are still plastered out of pure cement. It is gray and dotted with black stains. I don't know when and under what circumstances it was pasted.

The corridors are also wrapped in cement, and because of the various sundries piled up, it looks cramped and dark.

Jiang Yuan directly asked someone to hold the survey lamp, and first dealt with the traces on the door.

Entering the scene, there is only a small house with one bedroom and one living room. As far as the eye can see, including the bed, everything is dirty and messy.

Not only the kitchen at the entrance, but also the floor leather on the ground are warped everywhere. Needless to say, the deposit for renting the house will definitely not be recovered.

Mu Zhiyang and the others entered the room and skillfully turned on the survey lights, footprint lights, fingerprint lights, and so on.

The survey equipment was basically provided by Chiyong City, and their own surveys were just waiting in front of them, giving Jiang Yuan the opportunity for the first round of surveys.

This is completely different from the initial treatment.

Jiang Yuan took a rough look at the interior scene, and then started to build a board bridge while walking. The official name is Quick

Channel Pedal".

Chiyong City uses folded metal pedals, perfectly fitting the name Banqiao.Metal pedals are not as sharp as acrylic pedals, but they are durable and can be regarded as very middle-class exploration supplies.

In fact, looking at the criminal police equipment in a place, we can see the degree to which the local economy and the criminal police system are valued.

For units like Shanghai 803, there is no need to discuss cost-effectiveness. You can use whatever is good or new.If it doesn't work well, it's okay to replace or give it away.

A unit like Chiyong City is like a middle-class family. Everything must be cost-effective, and only buy necessities as much as possible. Necessities should preferably be durable goods, which can last longer and save replacement and maintenance costs.

As for units like Ningtai County, they are poor people in the criminal police system. Basically, everything is lacking and everything is poor. If you scrape together a little money, you can buy some urgent and necessary things. Look at the price, and finally chose the cheap one.

That is to say, after Jiang Yuan went out and sold it, the economic situation of 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 also paid attention to his operations.

Similar to forensic doctor Qiu Xing, in Chiyong City's trace inspection, the two main players can also have a level of 2.

This is also a result of practice. If the trace inspection of a prefecture-level city does not have a LV2 trace inspection, the detection rate will be broken down in a maximum of two years.

But if there are no more, a few young tracers should be smarter and solve cases one by one.

After one or two years of effort, it is also possible to develop a V2.

Of course, it is only possible, like Lao Yan from Ningtai County, who has practiced all his life and is still the strongest in V.

Jiang Yuan walked slowly along the Banqiao, watching as he walked, and when there were marks on the side, he didn't rush to wipe it off, but put a yellow sign on it first.

Jiang Yuan went all the way to the innermost part of the room, which is where the bed was, before he began to formally search for traces.

Most of the trace inspections use various lights to illuminate the traces, and then scan the traces when they are illuminated.

Only in rare cases, the trace inspectors will scan the traces inch by inch.For example, Jiang Yuan used this method when he did a second survey before.

Of course, criminals in most small cases are not entitled to this level of treatment.

This time, Jiang Yuan didn't plan to sweep so carefully.

The main reason is that the identities of the three criminals have been confirmed, and the value of their fingerprints and footprints is actually not high. The core now is to find some other clues to help the subsequent pursuit.

The trace investigators from Chiyong City also slowly spread out, picking up the traces behind Jiang Yuan and collecting them.

Jiang Yuan sees more and does less.

LV4 crime scene investigation, working in such an indoor environment, already belongs to the level of excess firepower.

To fully utilize LV4's crime scene investigation, at least it must be at the level of the previous stabbing case, that is, the outdoor environment, where people are constantly coming and going, and the scene has been destroyed more than once, and then there will be traces that cannot be collected. indistinguishable situation.

Like the three criminals in this murder case, they were a little cautious at the crime scene, but after returning to this temporary foothold, their cautiousness dropped greatly.

In fact, most criminals are like this.Many people will carefully analyze the situation before committing a crime, and will design the method and method of committing the crime, but after they really succeed, they relax all of a sudden, and it is easy to reveal their flaws.

The kind of people in 1937 who can maintain concentration, maintain high-intensity attention for a long time, self-control, emotional stability, follow the established plan, and perfectly complete the work of self-design, even if they commit crimes, they are usually not so low-level crimes against property.

Without much collision, Jiang Yuan didn't need to take most of the traces, and he could even reconstruct the scene.

He watched it for a long time, at least 20 minutes. After finally entering the bathroom, Jiang Yuan squatted down slowly

"How old are the three criminals?" Jiang Yuan asked suddenly.

"More than 20 years old, number one is the oldest, 28 years old, then 26 years old, 24 years old."

Liu Jinghui stood by and watched, and asked, "Is age related to traces?"

"Piss is everywhere in front of the toilet."

If it's three young men in their 20s, it's more than that.

Jiang Yuan pointed to the area around the toilet in the bathroom.

There are very shallow urine stains, but the distribution area is almost all over the three sides of the front of the toilet. It can be seen that the urine is scattered when urinating.

The middle-aged Liu Jinghui was very familiar with this scene, and immediately nodded and said, "Indeed, this person has kidney deficiency at first glance.

The three criminals were young and strong, and they couldn't urinate to such an extent. "

Give me a swab. "Jiang Yuan squatted again, and then began to carefully extract the urine marks around the toilet."
