Chapter 638

With Jiang Yuan's voice, Qian Tongyi almost squeaked past him, only to feel his heart pounding.

Qian Tongyi is the captain of the criminal police team in charge of the Shanggeyong case. He has a lot of psychological pressure and heavier responsibilities. He finally sees the dawn of victory. He spends less time during the day to catch up on sleep than Jiang Yuan. He focuses on hard work.

However, all of the above is based on the fact that Shang Geyong has been found, the murderer has been identified, and the case has shifted from the stage of detection to the stage of chasing and fleeing...

When Jiang Yuan said, "The deceased was not Shang Geyong", Qian Tongyi's eyes went dark.

In this year and month, there are still wrong people?

"Is it still there?" Qian Tongyi leaned on the wall, looking like a middle-aged man peeing to the end, and asked, "Is it confirmed? Do you know who the deceased is?"

"The age and bone traces don't match up. The DNA laboratory has not yet produced results, but it should not support Shang Geyong." Jiang Yuan paused, and then said: "It is not yet sure who the corpse belongs to. .”

"This Shang Geyong...he can decorate a house, but he can still decorate a corpse? We have to start all over again!" Qian Tongyi was bitter.

"It's not that new. Shang Geyong really disappeared, and the mobile phone number of the worker who built the wall was indeed lost, and he disappeared." Jiang Yuan told the existing facts, which can be regarded as a little comfort Let's talk about Qian Tongyi.

In terms of the number of homicides and serious cases he has done, Jiang Yuan may be doing more than Qian Tongyi now. Moreover, solving cases with technology will be more stable in the first place.

Qian Tongyi took a deep breath, thought again, and said: "Forget it. So, this wall builder is still very suspicious. If Shang Geyong... If he is not an accomplice, why didn't the murderer kill him together?" So, does Shang Geyong also have serious suspicions?"

"In this regard, I have a little other idea." Jiang Yuan said it directly when he had an opinion. At this time, he didn't need to pay attention to EQ or anything. He made a 1V1 phone call and immediately said: "The first point, the murderer may have thought , but couldn’t handle it in time. It was already early in the morning, and I don’t know how long Shang Geyong had been on the road, and it shouldn’t be long before the start of work in the morning. Someone will probably come to work next.”

"In addition, the murderer killed a person and got a lot of quicklime. Then he had to dig out the internal organs, paint the abdominal cavity, and then build the wall, carry it, etc. It is likely that there is no time and energy to repeat such a process."

Jiang Yuan continued: "Second point, the level of the murderer's wall-building is relatively high, and there is a level of LV2. To put it simply, the murderer has three to five years of experience in wall-building. If you are more experienced. Go back and find the wall that this person built, and make a comparison."

The more Qian Tongyi listened, the more he didn't understand: "Is it possible to make comparisons by building walls?"

"Of course, the marks left by the tools used to build the wall can be compared. The basic scratches on the wall can also be seen from the tools used. The inclination of the wall, the ratio of the wall to the cement, etc..." Jiang Yuan I didn't tell the Muggles too much, as long as it happened.

He had acquired the LV4 wall-laying skill before. Although he hadn't used it much, it was enough to see the state of the finished product and guess the skill level of the wall-builder.

Qian Tongyi said "hmm" twice, although he felt that what Jiang Yuan said was unbelievable, but thinking about the rumors about Jiang Yuan he had heard before, it seemed that something as far-fetched as forensic botany really existed, and building walls could be counted. what.

"That is to say, the wall builder is still the mastermind. He didn't have time to deal with Shang Geyong, did he take Shang Geyong away?" Qian Tongyi tried to reason.

"It's possible. Are the surveillance cameras in the community not available? Let's look for the nearby surveillance cameras." Jiang Yuan is not good at guessing out of thin air, just making some guesses from the state of the corpse and so on.

Qian Tongyi seemed to be recovering, and said: "I'll look for a map detective to grind it out. By the way, the identity of this corpse has not been confirmed yet, has it?"

"Not yet, we are waiting for the confirmation from the DNA laboratory."

Jiang Yuan can actually imagine that not long ago in the DNA laboratory, the experimenters must have been frantically comparing the DNA test results.

A layman sees a DNA test result as a conclusion, often verbally described as "supported."But in the DNA laboratory, the output of the instrument is actually a "wave".

Therefore, the original data of DNA identification is a bit like an electrocardiogram, more precisely, like the data of a mass spectrometer, the position and height of the peaks and valleys determine whether the same site matches, and multiple sites must match to be identified as the same.

Shang Geyong's samples could not be the same, and the technicians' first thought was that the samples were contaminated.

It wasn't until Jiang Yuan called that the director of the DNA laboratory breathed a sigh of relief.

……

In the evening, the DNA laboratory finally released the identification report.

At this time, Jiang Yuan and the others had already started eating hot pot in the forensic office.

A forensic laboratory is not an anatomy room, as the name suggests, is primarily an office component.Entering the door is a desk and other things, including normal office supplies, and computers.The forensic laboratory in Changyang City is in good condition, and there are several rows of cabinets. The appearance is similar to the financial cabinets, and they are all small and small. They are mainly used to store forensic evidence, that is, bone fragments and the like. .

In addition, there are several cabinets containing objects such as specimens, which are mainly used for related experiments and research, as well as decorations.

However, even though it looks like an ordinary office, ordinary colleagues will not come here for a walk. If there is anything, they will mainly call.

During the day, the forensic office is relatively busy. After all, apart from Shang Geyong's case, the laboratory also serves other criminal police teams and cases.But at night time, the office will be much more free.

Some forensic doctors will choose to use a microscope to look at human body slices in the dead of night, because this time period is relatively quiet, and they can read these things slowly and without a sense of urgency. Facts have proved that there is no accurate progress and no standard completion for this kind of time. As far as the content of the work is concerned, the effect is the most significant if it is carried out without pressure.

Jiang Yuan likes to eat hot pot at this time.

Therefore, today's Changyang City Forensic Medicine Office started eating hot pot.

"The intestines are cooked."

"Put the brain in a colander and cook it for a while."

"The belly can be eaten in a few seconds, it's very crispy."

The steaming hot steam drifted upwards, and the bright lights became distorted and hazy because of this.

This is what Yu Wenshu and Huang Qiangmin saw when they pushed the door in.

"The rest."

"Huang Ju." Jiang Yuan still called Huang Qiangmin that way.

Huang Qiangmin smiled as usual, and Yu Wenshu asked with a confused expression: "Is it the animal offal that I bought?"

"What do you want to ask is bought, or animal offal?" Wu Jun, who was evaluated as a deputy subject, had already let himself go, and dared to joke with Captain Yu, who was [-] levels higher than him.As the saying goes, when a person will retire, he will see a senior official.

Yu Wenshu smiled wryly and shook his head: "I'm here to express my condolences to you, it seems that I don't need it."

As he spoke, someone carried a snack box and put it on the table, and then asked Jiang Yuan: "The identification report from the DNA laboratory has come out, have you received the news?"

"Received. The deceased is the project manager of the construction company?" Jiang Yuan asked.

"Yes, that's it. This decoration company is really unlucky, and I don't know how to lose money in the future." Yu Wenshu has experienced many similar things, and he doesn't need to discuss the law. He knows what's going on with his eyes closed.

Jiang Yuan thought for a while, and said, "Is this wall builder hired by the project manager temporarily, or is there a long-standing grudge?"

"It's still Jiang Yuan, I immediately thought of an idea, and I came here for this." Yu Wenshu sat down while speaking, and said: "After our police's inquiry, some decoration managers or foremen of this decoration company , I have the habit of looking for temporary workers in the decoration market. In fact, I have encountered this kind of job when I was doing renovations. You don’t need to sign a contract, and you don’t need an ID card. The daily salary is about 400 a day. Five or six hundred, some with materials, all different..."

Jiang Yuan said "um", he was quite familiar with this part.

Yu Wenshu and Huang Qiangmin looked at each other, and said: "We figured this worker was not working for the first time, so we checked the situation of the project managers in several relatively large decoration companies in Changyang City. It turns out that at least three project managers are now missing."

Jiang Yuan blinked, recalled the TV wall built by the murderer again, and couldn't help saying: "There are still those in the wall."

"Someone brought a portable X-ray machine to take pictures, and the results should be available soon." Yu Wenshu said as he sat by the side of the hot pot, as if we were waiting for the results together, sharing the joys and sorrows together.

　During the day, all kinds of things are not going well, when I am sleepy, I write again, write and revise, revise and revise, and at night, my thoughts are flowing like a spring, alas, I want to adjust my schedule...
