Chapter 820: Anti-corrosion

Liu Jinghui brought his brain and went to the Map Investigation Detachment with Jiang Yuan.

In the command center of the Changyang City Map Investigation Detachment, it was filled with all kinds of screens. I don't know if they were useful, but it really felt like high-tech. Several criminal police officers of the Map Investigation Detachment also looked like they were educated, and there were those who could change angles by operating the keyboard with both hands.

Liu Jinghui stood behind, watching Jiang Yuan direct several criminal police officers to walk the video. His eyes were fixed on the screen in front, but he was actually distracted.

There are many cases handled, and sometimes it is a burden. For Liu Jinghui, he has done simple and exquisite small cases, cruel and bloody major cases, important cases cared about by leaders, and mysterious espionage cases. And these cases, applied to today's case, seem to be possible.

From the identity of the murderer, it could be ignorant passion killing, or it could be a well-planned murder. Similarly, professional means of professionals cannot be ruled out.

If this were an American blockbuster, what Liu Jinghui has to consider now is a former CIA agent, or a KGB spy, and terrorists must be the relatively advanced kind, to be able to research in the laboratory, a secret medicine that can disrupt the time of death.

Of course, if it were just a reasoning novel, what Liu Jinghui has to consider is some means that ordinary people can use. For example, the method that has appeared in movies, by lowering the temperature of the air conditioner, delaying the time of corpse decay, this method is similar to putting food in cold storage, relatively gentle, and it is very difficult to find if you don't pay attention.

Turning his thoughts, Liu Jinghui's brows furrowed deeper.

The murderer racked his brains to disrupt the time of death, there must be a purpose. Usually, this is a situation that only occurs when acquaintances commit crimes, and the purpose is to create an alibi for the murderer.

In Japanese TV dramas where reasoning dramas are very popular, there are often such scenes. First, the murderer is running, racing against time to create an alibi. Later, the protagonist starts running, thereby proving that the murderer has the time to commit the crime, excluding the murderer's alibi time. Then you see him running and running, towards the sunshine, towards the dream, that hard work, is exactly the... father of the Heisei man.

"The victim's father is dead. Are there any other close relatives?" Liu Jinghui pulled his train of thought back.

The criminal police officer next to him quickly flipped through the file and said: "There are no direct relatives."

"Make a table of the acquaintances he communicated with the most and arrange them." Liu Jinghui turned to Wang Chuanxing and said. This work is not as simple as it sounds, and he is not at ease letting an unknown small criminal police officer do it.

Wang Chuanxing responded and asked: "Do you think it is still an acquaintance committing the crime?"

"It's hard to judge." Liu Jinghui sighed, said the speculation he had just thought of, and said: "If the murderer's purpose is to create an alibi, this is what acquaintances need to commit crimes..."

Liu Jinghui paused, and then said: "It is impossible to determine how he did it at present, but judging from common sense, the probability of acquaintances is relatively large."

"Then I will give feedback to Captain Ma. Their original plan should also be to check the circle of acquaintances first." Wang Chuanxing took out his mobile phone.

Liu Jinghui nodded, and his brows did not loosen at all.

If this case could be solved so easily, it wouldn't deserve it! And if there is no result in checking the circle of acquaintances, where will this case go?

Liu Jinghui stood in the hall, turning his brain, thinking crazily.

Jiang Yuan also directed several people, constantly brushing the surveillance video from a few days ago.

Late at night.

The night was slightly thick, Jiang Yuan just released the mouse and said: "In this position, it is indeed difficult to determine suspicious vehicles."

Jiang Yuan's tone was somewhat disappointed. With his technology, as long as the surveillance screen captured it, even if it was a little blurry, he could restore it with image enhancement.

In addition, the LV3 technical defense surveillance system belongs to the skill of understanding the surveillance system from the bottom layer. He can build a whole set of surveillance systems, so using it is naturally not a problem.

However, all these skills are very easy to use, but there are no suspicious vehicles, and no matter how good the skills are, they cannot be used.

"Looking at it this way, the murderer may still be relatively familiar with the nearby environment, and at least be able to avoid the intersections with surveillance." Liu Jinghui said, and his brows furrowed again.

Mu Zhiyang whispered on the side: "This... didn't it just say before that it was an acquaintance committing the crime?"

"Acquaintance committing the crime is inferred from common sense, and there is no evidence to support it." Liu Jinghui shook his head.

Mu Zhiyang's brows also furrowed: "Doesn't reasoning require evidence?"

"Who said reasoning doesn't require evidence!" Liu Jinghui heard this, and his small violent temper was instantly ignited. He rolled up his sleeves and said: "You wait a moment, I will explain this problem to you properly..."

"Division Chief Liu..." Jiang Yuan interrupted quickly and said: "Let's go back to eat."

"If the case cannot be solved, there is no way to sit down and eat properly." Liu Jinghui sighed and said: "Let's go back and get some instant noodles to eat."

"Don't, there are plenty of opportunities to eat instant noodles. If you want to eat noodles... I will make a phone call." Jiang Yuan's mood was still stable, the frustration of not being able to break through the case flashed away, and he quickly made a phone call, and then said: "I will have people send a pot of noodles to the police station, let's eat something together. By the way, does Division Chief Liu want to go home to eat?"

Liu Jinghui twitched his mouth twice, looked at the sky outside, and said: "What can I eat if I go home at this time? Just pretend I'm on a business trip."

Jiang Yuan and the others were really on a business trip, and there was nowhere to go. A group of people gathered in the canteen of the Criminal Investigation Detachment, waiting for the chef to cook noodles.

What Jiang Yuan had people send over was cooked beef soup and beef. The chef directly took the noodles out of the noodle pressing machine, threw them into boiling water to cook, then poured the soup, put the beef, and then threw a handful of chopped green onions and coriander, which was considered to be this bowl of beef noodles that was not beef noodles.

This dinner actually only has one key point: the soup is a thick soup boiled with a large amount of beef and beef bones, and then, put more beef.

A bowl of noodles, half a bowl of soup, plus one-third of a bowl of beef, how the noodles taste, how the seasoning is, and how the side dishes are, it doesn't matter at all.

There are many young and strong police officers in the special task force. When eating noodles, they are one bowl after another. The three chefs in the canteen, one person pressing noodles, two people cooking noodles and scooping noodles, barely managed to supply them.

Jiang Yuan ate three bowls of noodles heartily before pushing the bowl away and resting for a while.

At this time, Wan Baoming clamped a file bag and hurried over.

"The new report from the physical and chemical laboratory, let you take a look." Wan Baoming didn't joke, meaning this was a serious matter.

"Change a table." Jiang Yuan stood up directly, changed to a clean table next to him, and then opened the file bag to read.

The physical and chemical laboratory is mainly a place for physical and chemical determination. This kind of laboratory sounds very high-end, but in fact, like the toxicology laboratory, it can only read or recognize familiar compounds. Therefore, if it is an ordinary case, the physical and chemical laboratory will do routine determination and then give a conclusion.

However, when encountering major cases, or encountering "senior police officers" like Jiang Yuan, the inspection items of the physical and chemical laboratory have to be expanded. Common compounds have been measured, and uncommon ones have to be measured continuously, so that the laboratory staff have been busy until the evening.

And the physical and chemical report brought by Wan Baoming is the result of being busy until now.

The first page of the file bag is the main achievement of the physical and chemical laboratory, a red line, which is the hard work of the physical and chemical laboratory.

"Cefoperazone sodium tazobactam sodium?" Jiang Yuan read it once and reacted quickly. This thing is for injection, the treatment effect is excellent, and the bacteria it can kill are not only useful on living people, but also useful on dead people. If the amount of injection is large enough, the residue after death can definitely reduce the decay after death and play the role of a preservative. ===== CHAPTER 821 =====
