Chapter 529: Rapid progress

In front of the dark red long conference table, Xu Ju Tian's brows were tightly wrinkled. Those who are familiar with him, every time they see this expression of Xu Tian, will raise their buttocks three inches when walking.

It was quiet all around, as if the dozen or so people in the room were holding their breath.

"Haha..."

Xu Ju suddenly laughed with his throat suppressed.

Then, there was low laughter in the conference room.

"What to do?" Xu Ju asked the director sitting in the middle while laughing.

In front of him were the two reports sent by Jiang Yuan.

Two murder cold cases, two clear investigation ideas, two clues, also mean double resource investment.

Not to mention the case handling funds, first of all, the pressure on manpower for the two murder cold cases is a bit high.

The leaders of the Luojin City Bureau felt this happy trouble for the first time. When have they ever been so happy?

The director felt that he could let everyone be happy.

Criminal investigation is too bitter. Occasionally, having such a good thing is really worth being happy.

Several people at the conference table were really laughing as if their faces were pulled.

"Although it cost money, this return is too fast and cool." The detachment leader sighed. He wanted to keep Jiang Yuan too much.

Xu Ju also nodded constantly. The cost of helping Ningtai County establish and enrich the laboratory is very high, but the solving of murder cold cases is only more difficult.

A very simple logic, some current murder cases cannot be solved on time. After more than a year, looking back, using a more difficult way to do these murder cases that have become cold cases, they can be solved. The gap here cannot be described in words.

After everyone was happy, the director asked: "How is the investigation going? Is there any hope?"

Speaking of specific cases, everyone's smiles were all collected.

Being a criminal police officer is actually not a very happy thing. Or rather, being a criminal police officer is a very masculine thing. Its happiest and coolest time is very short, basically only the last few seconds. Before this, the criminal police need to sweat and take risks, bearing huge emotional fluctuations.

Like what the director said, the investigation of the acquaintance relationship of the Haidilao cook, if there is a result, it is naturally happy, but before reaching the end, all efforts are fruitless. And no one tells you where the end is.

The detachment leader took a deep breath and said: "The investigation is still going on. Currently... there is no result for the time being."

"This investigation direction... since it was proposed by Jiang Yuan, then you should continue to work hard." The director could have asked the detachment leader for his opinion first, but turned directly to give the conclusion.

He didn't want his subordinates to follow the trend and cleverly change the investigation direction. Because now there is another drowning case, since it is also a murder cold case, if this case is solved, he will not be able to blame, not only cannot blame, but also must praise well.

It's just that in this way, the Haidilao cook case doesn't know when it will be solved. The director certainly feels unwilling to see two murder cold cases become one.

As for whether to believe Jiang Yuan or his subordinates who have been familiar with each other and worked hard together for ten or twenty years, the director naturally chooses to believe Jiang Yuan.

Even if the acquaintance relationship of that cook has been screened several times, he still believes in Jiang Yuan.

The current Jiang Yuan, the cold murder cases he has done, are more than the number of murder cases many people have participated in in their lives. Even more than the number of special task forces many people have joined in their lives. From the director's experience, if you don't believe such a Jiang Yuan, who do you believe?

Don't look at the age, don't look at the technology, just look at the experience of doing murder cold cases, Jiang Yuan is also the top in the country.

Change to a normal criminal police officer, work for five or six years, start to do odd jobs for the special task force when he is in his twenties, and it is considered good to solve one major case on average a year—more likely it is two major cases, and only one is barely solved—not to mention having to chase and escape.

Working hard like this until he is in his forties, if he can still do it, he can solve ten or twenty major cases. How many murder cold cases can be counted in it?

From this angle, the director sees Jiang Yuan and his subordinates, not at the same level at all.

The detachment leader had to confirm with the director: "Should the investigation configuration be adjusted? If the new case rises, our manpower will not be enough. So it may need to be strengthened."

"How many people do you want?" The detachment leader opened his mouth and asked for a big one.

The director said "En," and bargained: "Give you 10 people, from... borrow a few people from below, count as many as you can borrow, borrow for three months first."

Nowadays, the police stations of the municipal bureau live by borrowing manpower from lower levels. The county bureaus below are painfully borrowed, and they have gradually developed some coping strategies. For example, strictly borrowing time, saying that borrowing for three months is three months. Another is that everything must be written on paper, and there must be documents issued to count.

The detachment leader also knows that manpower in all aspects is tight, sighed and said: "In this case... okay."

Anyway, it is to take water samples upstream at the beginning. If the manpower is slightly less, it will be taken slower, which he can accept.

The director said "En," and said: "I think it is two legs walking. As long as one case is solved, the manpower will be sufficient."

"Yes." The detachment leader can only respond.

Returning to the office, the scene of people coming and going in the past can no longer be seen.

The organ police officers were all driven out by the detachment leader, including deputy detachment leaders, etc., who are now leading teams to other provinces.

There are always some people who go far away to work. Inquiries about these people are indispensable. Leaving after the case is considered a suspicion item.

"Detachment Leader Wang." The detachment leader of the Second Detachment came to report: "We found a situation."

"Say." The detachment leader immediately had spirit. It has been so many days, and he has to eat two more bowls of rice every day to endure it.

"When we inquired about a former colleague of the deceased, we found that the other party's emotions were abnormal. After careful questioning, this former colleague admitted that he had a love relationship with the deceased."

The detachment leader was stunned: "Female cook?"

"Male cook..."

"Then... oh..." The detachment leader nodded. He is also well-informed, and his mind immediately expanded: "Their relationship was not public?"

"Yes."

"This is a new situation. So, the victim is a homosexual, and one who hasn't come out of the closet. What about his boyfriend behind? Is he on our list?"

The detachment leader of the Second Detachment said: "Yes, but not focused on inquiry, marked as C."

"Change to A, send someone to ask." The detachment leader rubbed his hands, and there was light in his eyes again. If there is no news about the Haidilao cook case, he can't help but change the investigation direction.

Jiang Yuan pulled Pang Jidong's Fourth Detachment and went upstream along the river.

Yesterday, he mainly did two things.

First, he judged as many algae as possible as accurately as possible. And the living conditions of different algae are different. Professionally speaking, the distribution water area is different. These parts can be distinguished on satellite maps, and some need to be judged on the spot. What is more troublesome than pollen profiles is that many algae cannot be seen. Maybe the water area meets its survival standards, but the proportion does not meet, and these need to extract water samples to test.

Second, Jiang Yuan made a more accurate inference of post-mortem immersion time. That is, how long the body has been soaking in the water.

This is a special feature of drowning bodies. Because after the body soaks in the water, the reproduction of insects and other microorganisms is affected, so judging the time of death through corpse-eating insects becomes unfeasible. Instead, the total time of death becomes more difficult to judge. On the contrary, there are many means to judge the time of soaking in the water.

For example, in fresh water, bodies soaked for a week will show skin peeling like "gloves" and "socks," that is, the skin of hands and feet falls off as a whole...

And judging the post-mortem immersion time, combined with hydrological data, can roughly judge the approximate section where the body fell into the water. However, the accuracy of this is much lower, and it involves many assumptions, so when arriving at the corresponding section, it must be combined with the first item to check.

Car stop.

Jiang Yuan got out of the car and looked into the distance, stood by the river and observed for a while, then pointed to a position, and someone came forward to throw the bottle to sample, put it once every few meters, collected enough, and then transported it to the car.

Jiang Yuan walked all the way, pointing all the way.

This kind of small and medium-sized river, the living environment is basically the same, very similar, but the distribution of algae is still different.

Pang Jidong and his subordinates carried boxes of small brown bottles, throwing them all the way, collecting a few boxes, and then rushing to send them back.

The laboratory was already prepared, and even new centrifuges were purchased. The most time-consuming part of the nine-step method is centrifugation. In fact, a pure diatom has to go through three centrifugations before it appears under the microscope, which is quite difficult.

Walking along the left bank for about three or four kilometers, and then returning for three or four kilometers, even if Jiang Yuan doesn't need to sample himself, this work intensity is extremely exhausting.

Fortunately, the sampling of algae in the laboratory is a mature technology, and Jiang Yuan doesn't need to operate it specifically. After going back to sleep, the next day... continue to centrifuge and sample...

And from the second day, Jiang Yuan needed to participate in identifying algae samples.

This work can only be done by him. Others want to help but can't, and can only watch.

Thus, in the courtyard of the Luojin City Criminal Police Detachment, only the people of the Fourth Detachment were left, floating around like wandering souls.

The detachment leader looked out from the office, resisting the urge, and did not drag this group of people out to work.

Other detachments were almost busy to death, and the Fourth Detachment actually had people kicking grass. If it were before, it would be fine. Now that the Haidilao cook case has new discoveries and new clues, it is the time when people are needed.

The detachment leader thought while moving to the laboratory, without any other meaning, just to greet Jiang Yuan, see if he likes the current working environment, and when he is ready to use people...

Arriving at the laboratory, the detachment leader sat on the chair in the reception room and waited. The operation room inside is dust-free, and it is very troublesome to go in once. The detachment leader is also too lazy to go over.

He himself is also preparing to ponder the words to meet later.

Just thinking about it, he saw Jiang Yuan walk out of the door.

"Forensic Doctor Jiang." The detachment leader felt inexplicably guilty and stood up hurriedly.

Jiang Yuan was a little strange why the detachment leader was here, but when he met, he said: "I am preparing to report to you. The entry point of the body has been determined. I checked the missing persons nearby and determined the victim's identity. He is a local resident and lives in a self-built house with his parents and brothers. His family has some problems. The report was too late, and they at least know something."

The detachment leader nodded constantly.

This situation can be called a major suspicion.

"By the way, what is the matter with you coming over?" Jiang Yuan took off his white coat.

The detachment leader handed it over, helped him hang it up, and smiled: "Nothing, just see if there is anything that needs service."

Double monthly tickets at the last moment, remember to vote for monthly tickets~ ===== CHAPTER 530 =====

The detachment captain took it from him, helped him hang it up, and said with a smile, "It's nothing, just checking to see if there's anything you need help with."

It's the final moments for double monthly tickets, everyone remember to vote!
