Chapter 429: Exclude Everything Impossible

Investigation in four directions.

Investigating accumulated cases is the most manpower-consuming. Especially this kind of old case with unclear purposes, just making inquiry records is longer than making current cases. Things from 8 years ago need time to recall, need evidence to confirm, and writing more than ten pages of paper may not be able to grasp the key points.

Making inquiry records is still a relatively easy thing, finding people may be more troublesome and difficult, and it also costs more time.

After doing such a homicide case, it is said that several missing persons can be found.

The criminal police in Qu'an County Bureau have no complaints at all, working in pairs, all busy, according to the list, asking one by one, finding people, and re-checking the information of the year.

The captain of the criminal police brigade also sat in the middle, didn't go home for three days, sat in the conference room every day, kept calling, kept smoking, kept communicating up and down, kept smoking, smoking, smoking.

Morning.

Liu Jinghui, who slept in the office, crawled out of the sleeping bag and found that the captain of the criminal police brigade had his eyes wide open, holding a few sheets of a4 paper and looking at them fiercely, and couldn't help but feel a sadness from his heart.

He has 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 okay for your wife to wait for you for a day or two, but it's not okay 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 Jinghui "ha" said: "My home is in Changyang City, I am here on a business trip now."

"Is there no traffic jam in Changyang City? You have to run for an hour or two."

"Is there no traffic jam in Changyang City? You have to run for an hour or two."

Captain Han curled his lips: "If you don't even have the qualification to choose a time when there is no traffic jam to come back when you work overtime all day, what is the meaning of your work?"

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

"I found that you speak really like my wife!"

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

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

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

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

The impact of the station explosion case is still very large. Now that there is a chance to solve it, the Qu'an County Bureau cherishes the opportunity very much.

Otherwise, they would not have invited Jiang Yuan to do this case despite the risk of being scolded as a "worker thief" by other county bureaus.

Jiang Yuan's fame is unquestionable, and Liu Jinghui also has quite a bit of fame. It is difficult to invite one of them on weekdays, but now two are invited in one breath. Without pre-war mobilization, the criminal police in Qu'an know that the opportunity must not be missed. qqxδnew

Furthermore, how high the cost of inviting Jiang Yuan is, the police officers in Qu'an also know a little bit, and Captain Han knows even more what he has paid.

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

And it is by time.

Thinking about it, it is 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 think about farting.

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

Actually, doing normal cases in normal years doesn't need to be anxious, and it doesn't need so much funding, so many personnel, so many vehicles, so many instruments and equipment, so many equipment and police weapons... Just give a little to people!

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

Liu Jinghui knew what he meant, "um" said: "Sometimes it is like this."

"Can you still find it?"

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

Liu Jinghui sighed helplessly.

Compared to other violent cases, the suspect of the explosion case is relatively 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 criminal must at least understand a little bit of electrician common sense, and be able to twist two wires together.

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 information is not something that can be obtained by reading newspapers casually. At the very least, the criminal must have read some book reviews.

Comprehensive minimum requirements, the criminal must be literate, able to read, understand a little bit of the basic principles of explosion—don't underestimate such requirements, it can screen out most people on the list. This is like using 985 to screen 857, and it screens out 90% of people casually.

The reduction of the suspect list naturally makes people feel heavy. This kind of screening method, the most expected situation is to screen to the middle and get results. The situation of getting results at the end is very rare.

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

From Captain Han's perspective, it is equivalent to these three days, his own brigade of more than 100 people, all doing white work.

Or rather, it has become a trial-and-error cost.

Although Captain Han has nothing to complain about, he still couldn't help sighing: "Director Liu, you judged the two pieces, saying that the killer committed crimes later, or committed crimes in other places. I was very agreeable, but now that I have done it, will we have missed something?"

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

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

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

A resentful look full of skills still played a little role.

Liu Jinghui was slightly moved, sighed, and said: "Let's say, actually, according to my experience, the multiple lists of multiple plans will actually have intersections. The killer cannot just appear in 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 is the use of talking about these theories now, give me something real." Captain Han said.

"Real..." Liu Jinghui was forced to have no way,

simply said: "Look at how real you want. If you want something real, you should find Jiang Yuan."

While talking, Jiang Yuan and Mu Zhiyang pushed the door in.

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

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

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 Jinghui was another sentence, mobilizing Captain Han's mind.

Jiang Yuan was also immediately attracted attention.

"Are they all excluded?" Jiang Yuan asked.

"Basically." Liu Jinghui said.

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

"Ah... who said reasoning is not working!" 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 to 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 has been a few days since the start, and Jiang Yuan hasn'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's just that it didn't play a role.

For a long time.

Liu Jinghui pondered and opened his mouth: "According to the truth, investigating from the motive of the crime, it can't be investigated anymore, so it should be investigated according to the method of the crime. However... the previous special case team checked this piece very thoroughly."

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

"Which one?"

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

For those who do reasoning, just thinking about this sentence can make their hair stand up with excitement.

Unfortunately, there are only a few pragmatic criminal police officers at the scene, like silent laymen.

Captain Han is the oldest, controlled by the sophistication of adults, sighed, and said: "Director Liu, can you tell me specifically?"

Liu Jinghui nodded with satisfaction and said: "After this case was determined to be an explosion case aimed at unspecified many people, it can be said that it was screened again and again. In the past few days, we have also included the time factor into consideration and screened it again, but we didn't screen anything."

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

"Since this is the case, I think, maybe we can exclude the explosion case aimed at unspecified many people!"

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

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

"What if it's a case targeting a specific person?" Liu Jinghui's voice deepened as he said, "What if we treat this case as an ordinary murder investigation?"
