Zhengguang District Branch.
Jiang Yuan followed Liu Cheng and received countless stares from the moment he entered the door.
He was tall and different from ordinary people, which was a very obvious feature. Then he followed Liu Cheng, and almost all the staff inside and outside the branch, inside and outside the establishment, recognized him.
Ningtai Jiang Yuan, fierce and fierce.
This sentence was spread by Liu Cheng, at least in the Zhengguang Bureau, and it was widely spread.
No one doubted anything. The land of China is full of outstanding people and geniuses. People in the capital are well-informed. Facing all kinds of young talents, they are simply overwhelmed and have no time to be shocked.
However, when geniuses come to my branch, they can't help but secretly test their purity, just like people tirelessly compare the quality of the rich people on the Forbes list-Tejun is comparable to Ciqing, but Cijun is richer.
Everyone looked at each other through the window, looking at Jiang Yuan, and they were also discussing:
"Solving a case can't be accumulated. Even if Sherlock Holmes came, he would probably have to wait and see if he encountered such a headless case."
"Insufficient evidence, Conan came, he could only bow his head and pretend to be a primary school student."
"There is no evidence or clues. Ningtai Jiang Yuan... probably just came to take a look. The population density and population flow in Beijing are more controlled by a neighborhood committee than in a county."
"That's not the case. Maybe they have something to say."
...
Conference room.
Liu Cheng's immediate superior, Criminal Police Detachment Captain Tao Lu, came early to see what Jiang Yuan could say.
The same murder case must be solved, but it is slightly different in the county and Beijing branches. In short, the murder rate in big cities is higher, and there will always be times when it cannot be solved, and the tolerance of superiors is higher. The murder rate in counties is low, and if it cannot be solved, the superiors will not tolerate your bad habits.
Of course, for business leaders, such as Criminal Police Captain Liu Cheng or Branch Captain Tao Lu, it is still very uncomfortable if a murder case cannot be solved. If criminal investigation is regarded as a project system, it is equivalent to the failure of the largest project to be completed.
Tao Lu looked up and down at Jiang Yuan, and felt that he was younger than the interns under him.
Many interns in the Beijing Branch came after graduating from a master's degree, and they are really older.
However, Tao Lu has plenty of patience, so he sat down and drank tea, ready to listen carefully to Jiang Yuan's ideas for solving the case.
At the conference table, several other criminal police captains who came with him also had similar ideas.
Then, Jiang Yuan spoke:
"Forensic botany..."
"Tool mark inspection..."
"Ulala la la la..."
"Forensic evidence..."
Tao Lu felt that his brain was hot, as if knowledge had knocked on the door, an old donkey had reclaimed the land, a technician had broken his rules, and a key had been inserted into the keyhole...
Jiang Yuan spoke for a quarter of an hour, and he had completed the case analysis.
When Jiang Yuan stopped, the meeting room, which was supposed to continue the discussion, was silent.
Everyone was busy thinking, and they couldn't use their mouths for the time being.
Jiang Yuan picked up the teacup and drank water. It was ordinary tea, but in the unit, it should be considered a good tea. It didn't taste astringent, and had a slight sweet aftertaste. Most importantly, it was not jasmine tea.
After a while, Tao Lu came to his senses and winked, letting his subordinates speak.
The captain of the third brigade next to him was a squinty-eyed man. He coughed twice and said, "Forensic doctor Jiang's plan is mainly based on technology. This... I don't know much about technology. Can forensic botany find the exact location?"
When Jiang Yuan goes out, he has at least one-third of his emotional intelligence. At this moment, he doesn't care about cause and effect at all. He said, "I do forensic botany, mainly in the laboratory. I have the staff with me. The equipment is very simple. It's okay to do it here or take it back. If you have other investigative ideas, don't delay. Just continue."
The pollen and spores on the clothes are those. Although Jiang Yuan hasn't seen them yet, as he said, the other actions of the criminal police detachment here do not affect the performance of the evidence. In this case, they are basically two parallel lines.
Jiang Yuan just provided a new investigative idea, and there is more chance and possibility of completion.
In the game, Jiang Yuan's approach is equivalent to adding an equipment, not replacing an equipment, at least it is an enchantment effect.
As a leader, there is no one who doesn't like Jiang Yuan's way of doing things.
It is not clear what the actual effect is, but the effect on paper has been greatly improved.
Tao Lu, the detachment leader, immediately said: "We fully support the technical conditions, equipment, etc. required by forensic doctor Jiang. The specific experimental plan and experimental conduct will be operated by forensic doctor Jiang... How can we cooperate?"
"Let's take a look at the conclusion of forensic botany first." Jiang Yuan introduced: "Through forensic botany, we can see the relationship between location and personnel."
"Well, it would be good to have a range." According to Tao Lu's idea, even if you are talking about the relationship between location and personnel, there are so many types of flowers and the capital is so big, it is still like looking for a needle in a haystack.
But he didn't understand the meaning of the pollen map.
Jiang Yuan couldn't give him a universal education, so he just smiled politely, like an old hen hatching eggs, looking at a preserved egg lovingly. Huang Qiangmin said that the Beijing Bureau is a wealthy government office. The Zhengguang District Branch alone has an annual budget of 2.2 billion, not to mention the fixed assets and intellectual property rights accumulated over the years.
It can be said that this kind of large government office with nearly 10,000 people is really enough for the Ningtai County Bureau to live a lifetime if there is a little leakage through the cracks. Moreover, the accumulated cases they have accumulated over the years will only be more, and they are indeed a good...cooperation partner.
Tao Lu didn't even understand Jiang Yuan's expression, and smiled reluctantly, saying: "Okay. I'm relieved about Forensic Doctor Jiang. Each team will report in turn, and let Forensic Doctor Jiang know the latest case."
In fact, there is nothing to understand. Although Tao Lu sent out a team of hundreds of people with just a little effort, which is more than the quota of the Ningtai County Criminal Police Brigade, it is too difficult to make a breakthrough in such a big city with only two blood-stained clothes.
Several teams of police explained their own search work. Theoretically speaking, although no clues or correct answers were found, some of them were ruled out.
Jiang Yuan made a brief note, and after the meeting, he followed Liu Cheng to the laboratory.
Along the way, Liu Cheng was still a little embarrassed and said, "In fact, it's almost time for dinner. You can eat first and then come here to slowly get familiar with the equipment here."
"Forensic botany does not require any special equipment, just a suitable microscope will do." Jiang Yuan paused and said, "You need to concentrate on collecting pollen. If the laboratory conditions are good, I won't go out for dinner."
Liu Cheng hurriedly said, "You don't have to work so hard."
Jiang Yuan waved his hand. Forensic botany is a hard job, but it's good to show it to colleagues in the Zhengguang District Branch. After all, it's a big picture of 2.2 billion yuan in funding, and it has to be respected.
Forensic laboratory.
Under the incandescent light, three rows of tables are arranged in parallel, and behind them are seven or eight groups of long cabinets.
Although the arrangement is different and the area is much larger, in general, the forensic laboratory of the Beijing Bureau is not much different from that of Ningtai County.
The laboratory set up in the bureau does not perform dissections. The main work is to look at samples with a microscope.
In fact, most cases require forensic doctors to participate multiple times during the investigation process, and they are mainly for examining specimens. The proportion of secondary or even tertiary dissections often requested by the victims' families is very low.
Because of the destructive nature of forensic dissection itself, the most valuable evidence should theoretically be taken out in the first dissection, such as internal organs, brains, etc., which can be cut into strips, immersed in paraffin, and sliced with a slide spreader for preservation.
Therefore, in the forensic laboratory at this time, most of the cabinets that are as large as 20 or 30 sets of hangers are filled with sliced specimens.
If the special case team wants to trace an old case, they will find the specimens from these cabinets and then examine them.
In terms of scientificity alone, this method is more effective and cheaper than preserving corpses.
However, in this case, there would be no biopsy without a corpse. All Jiang Yuan needed was a microscope, evidence and a lot of time.
