Chapter 429: Excluding Everything Impossible

Investigation is everywhere.

Investigating cold cases is the most labor-intensive. Especially for this kind of old case with unclear purposes, just making inquiry records takes longer than current cases. Things from 8 years ago require time to recall, confirmation requires corroboration, and writing a dozen pages of paper might not even grasp the key points.

Making inquiry records is still a relatively easy thing. Finding people might be more troublesome and difficult, and also more time-consuming.

Doing such a homicide case, it's possible to find several missing persons.

The criminal police of Qu'an County Bureau had no complaints, working in pairs, all busy, following the list, asking one by one, finding people, and re-verifying the information from back then.

The criminal police brigade captain was also sitting in the middle, not going home for three days, sitting in the conference room every day, constantly on the phone, constantly communicating up and down, constantly smoking, smoking, smoking.

Morning.

Liu Liu Jinghui, who slept in a sleeping bag in the office, crawled out and found the criminal police brigade captain with his eyes wide open, holding several A4 papers and looking at them fiercely, and couldn't help but feel a wave of sadness.

He had experience, and couldn't help but kindly remind: "Old Han, you can't do this. At least go home to sleep at night. It's not bad for your wife to wait for you for a day or two, but it won't do for you to not return home day after day."

"You didn't go back either." Captain Han's eyes were as bright as matrix headlights.

Liu Liu Jinghui said: "My home is in Changyang City. I am here on a business trip now."

"It takes more than an hour to get to Changyang quickly. It's not too much to go back once in three days!"

"Isn't there traffic in Changyang City? You have to run for an hour or two."

Captain Han sneered: "If you don't even have the qualification to choose a time when there is no traffic to come back when you work overtime all day, what is the point of you working this shift?"

Liu Liu Jinghui said "Heh," and people were three inches taller.

"I find that the way you speak is really like my wife!"

"Same style wife." Captain Han curled his lips: "Going back for a day is scolded, going back for three days is scolded, it's better to wait for a week or two, and go back as a person."

Liu Liu Jinghui looked at Captain Han sympathetically: "Your life is a bit difficult."

"What's difficult or not for a criminal police officer? It's not bad to be alive. If you can solve the case, if you can solve the case for us, I will Amitabha." Captain Han's eyes were red from staying up late, looking like a true emotional outpouring, but actually, there was no emotion at all, all skills.

Of course, his urgent desire to solve the case was true.

The impact of the station explosion case was still very large. Now that there was an opportunity to solve it, the entire Qu'an County Bureau cherished the opportunity very much.

Otherwise, they wouldn't have invited Jiang Yuan to do this case while risking being scolded as "industry traitors" by other county bureaus.

Jiang Yuan's fame was unquestionable. Even Liu Liu Jinghui had quite a bit of fame. It was difficult to invite one of them on weekdays, but now they invited both of them in one breath. Without pre-war mobilization, the criminal police of Qu'an knew that the opportunity should not be lost.

Furthermore, the cost of inviting Jiang Yuan, the civil police of Qu'an also knew roughly. Captain Han knew even better what he had paid.

Using the NBA as an analogy, they were equivalent to exchanging several first-round draft picks, second-round draft picks, and several role players for Jiang Yuan alone in the next few years.

And it was per time.

Thinking about it, it was quite a loss, but immediate combat power is like this. You either rely on yourself to win, or exchange the future to win today, or just think about farts.

From Captain Han's perspective, such an expensive guy, if you don't use him up now, where can you go to sea-buy in the future?

Actually, doing normal cases in normal years didn't have to be anxious, and didn't need so much funding, so many personnel, so many vehicles, so many instruments and equipment, so many equipment and police gear... If you give a little to people, just give a little!

Captain Han sighed heavily: "The list is shrinking fast. From a notebook at the beginning, to a few pages now, there has been no strong news."

Liu Liu Jinghui knew what he meant, "Uh" and said: "Sometimes it's like this."

"Can you still find it?"

"If you can't find it in this wave, then the next wave. You are also an old criminal police captain. Solving a case is like this."

Liu Liu Jinghui sighed helplessly.

Compared to other violent cases, the suspect of an explosion case is quite special. He must first master relevant knowledge. Even if he hasn't learned it, he must have basic learning ability and learning foundation. For example, in this case, the killer must at least know a little bit of electrician common sense, and be able to twist two wires together, right?

The actual requirements are definitely higher. The explosion in this case actually has a certain innovation. Without a few years of relatively professional training, it is unlikely to think of this method. Even if it is copied, this kind of information cannot be obtained by just looking at newspapers. At the very least, the killer must read some book reviews to know.

Comprehensive minimum standard, the killer must be literate, able to read, understand electrician knowledge, and understand the basic principles of explosion—don't underestimate such a requirement, it can screen out most of the people on the list. This is like using 985 to screen 857, easily screening out nine out of ten.

The reduction of the suspect list naturally makes the mood heavy. This kind of screening method, the most expected situation is to appear results in the middle, and the situation of appearing results at the end is extremely rare.

Everyone is not really doing random algorithms. At the beginning, perhaps they were walking according to the list. In actual operation, they were definitely looking at the most likely suspects and searching all the way. In the end, when only the bottom of the list remained, the probability of finding it was very low.

From Captain Han's perspective, it was equivalent to his own brigade of hundreds of people doing useless work for these three days.

Or rather, it became a trial-and-error cost.

Although Captain Han had nothing to complain about, he still couldn't help sighing: "Liu Chu, your judgment of the two blocks, saying that the killer might have committed crimes later, or committed crimes elsewhere, I was very agreeable, but now that it's done, could it be that we missed something?"

He looked at Liu Liu Jinghui, expecting Liu Liu Jinghui to give a definitive answer.

However, Liu Liu Jinghui, who had just woken up, was not a dusty lady who did psychological massage. A cold sentence was thrown out: "It is very possible to miss something, but there is no way if you miss it. You can only follow other plans and come again."

Captain Han looked at Liu Liu Jinghui with a resentful expression, as if his people, his sleeping bag, and the white frost outside the window were as cold as him.

A set of resentful eyes full of skills still played a little role.

Liu Liu Jinghui was slightly moved, sighed, and said: "Let's just say, actually, according to my experience, the multiple lists of multiple plans will actually have intersections. The killer cannot just appear on one list. That is too testing luck. The most likely situation is that the killer constantly appears in our field of vision, and there will always be an opportunity that will allow us to lock onto him."

"What's the use of talking about these theories now? Give me something solid." Captain Han said.

"Solid..." Liu Liu Jinghui was forced to have no way, simply said: "Look at how solid you want. If you want something solid, you should find Jiang Yuan."

As they spoke, Jiang Yuan and Mu Mu Zhiyang pushed the door and entered.

"Oh, Liu Chu and Han Da are here. Did you sleep here last night?" Mu Mu Zhiyang said something discordant with a pure face.

Captain Han's face sank. Do you dare to tease me?

Liu Liu Jinghui coughed twice and said: "Did Mu sleep with Jiang Yuan last night?"

Captain Han's expression immediately closed: If this is the case...

"No results on the list." Liu Liu Jinghui said another sentence, mobilizing Captain Han's mind.

Jiang Yuan was also immediately attracted.

"Are they all excluded?" Jiang Yuan asked.

"Basically." Liu Liu Jinghui said.

Jiang Yuan was also a little disappointed: "It seems that reasoning is also not working."

"Ah... who said reasoning is not working!" Liu Liu Jinghui couldn't stand this the most. His mouth hissed, and he put on a Sherlock Holmes-style smile:

"Let me think."

Jiang Yuan signaled Mu Mu Zhiyang, and the two sat at the conference table, took out the photos that hadn't been finished yesterday from the storage cabinet, and then read them one by one.

It had been several days since the start, and Jiang Yuan hadn't even finished reading the photos and case files. It can be imagined that the scale of the investigation during the current case was large. It just didn't play a role.

For a long time.

Liu Liu Jinghui pondered and opened his mouth: "According to reason, after investigating from the motive of the crime, if you can't investigate, you should investigate according to the method of the crime. But... the previous special case team checked this part very thoroughly."

Liu Liu Jinghui said and looked at Jiang Yuan, slowly saying: "After investigating to the current degree, I think it is possible to take out that sentence often used in reasoning."

"Which one?"

"Excluding everything impossible, the remaining, no matter how incredible, is the truth!" Liu Liu Jinghui said this sentence, his whole body glowing with gold.

Doing reasoning, just thinking about this sentence, can make the hair all over his body stand up excitedly.

Unfortunately, there were only a few pragmatic criminal police officers at the scene, as quiet as Muggles.

Captain Han was the oldest, controlled by the sophistication of adults, sighed, and said: "Liu Chu, can you speak specifically?"

Liu Liu Jinghui nodded with satisfaction and said: "After this case was determined to be an explosion case targeting unspecified people, it can be said to have been screened again and again. In the past few days, we have also taken the time factor into consideration and screened it again, but nothing was screened out."

Liu Liu Jinghui clenched his fist with one hand and tapped it lightly, saying:

"If so, I think, maybe we can exclude the explosion case targeting unspecified people!"

"What do you mean?" Captain Han was stunned.

"What if it is a case targeting a specific person?" Liu Liu Jinghui's voice sank, saying: "What if we do this case according to an ordinary murder case?" ===== CHAPTER 430 =====

"What do you mean?" Captain Han was taken aback.

"What if this is a case targeting a specific person?" Liu Liu Jinghui's voice dropped, and he said, "What if we treat this case as a regular murder case?"
