Chapter 842 Anticorrosion

Liu Jinghui took his brains and went to the Scout Brigade with Jiang Yuan.

The command center of the Pictorial Reconnaissance Brigade in Changyang City is filled with all kinds of screens. I don’t know whether they are used or not, but they do look a bit high-tech. Several detectives from the Picture Detective Brigade also looked like they were educated, and some of them could change their angles by operating the keyboard with both hands.

Liu Jinghui stood behind, watching the video of Jiang Yuan directing several criminal police officers. His eyes were fixed on the screen in front of him, and he was actually distracted.

There are too many cases to investigate, which is sometimes a burden. For Liu Jinghui, he has done simple and exquisite small cases, cruel and bloody big cases, important cases that leaders are concerned about, and mysterious espionage cases. And these cases, when applied to today's case, seem to be all possible.

Judging from the identity of the murderer, it could be an ignorant murder of passion or a calculated murder, and the professional methods of professionals cannot be ruled out.

If this were an American blockbuster, what Liu Jinghui would have to consider now would be a former CIA agent, or a KGB spy, etc. The terrorists would have to be relatively advanced in order to be able to study them in the laboratory and disrupt the time of death. secret medicine.

Of course, if it were just a mystery novel, Liu Jinghui would have to consider some methods that ordinary people can use. For example, as shown in movies, lowering the temperature of the air conditioner delays the decomposition of corpses. This method is similar to refrigeration of food. It is relatively gentle and difficult to detect without paying attention.

On second thought, Liu Jinghui's frown deepened.

The murderer's efforts to mess up the time of death must have a purpose. Generally speaking, this is the case when an acquaintance commits a crime, and the purpose is to create alibi for the murderer.

In Japanese TV dramas, which are very popular mystery dramas, there is often a scene like this. First, the murderer is running, racing against time to create alibi evidence, and then the protagonist starts running, thus proving that the murderer had time to commit the crime and excluding the murderer's alibi time. , I saw him running and running, towards the sun, towards his dream, and that hard work was exactly Heisei-o's... father.

"The victim's father is probably dead. Are there any close relatives?" Liu Jinghui pulled his thoughts back.

The detective next to him quickly flipped through the file and said, "There are no immediate relatives."

"Make a list of the acquaintances he communicates with the most and arrange them in order." Liu Jinghui turned to Wang Chuanxing and said. This job is not as simple as it sounds, and he doesn't feel comfortable letting a young detective who doesn't know about it do it.

Wang Chuanxing responded and asked, "Do you think an acquaintance still committed the crime?"

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

Liu Jinghui paused, and then said: "At present, we are not sure how he did it, but based on common sense, the probability of being an acquaintance is relatively high."

"Then let me give feedback to the Ma Brigade. Their original plan should have been to check the circle of acquaintances first." Wang Chuanxing took out his mobile phone.

Liu Jinghui nodded without unbrowsing at all.

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

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

Jiang Yuan also directed several people to continuously review the surveillance videos from a few days ago.

evening.

The night was slightly dark, and Jiang Yuan just let go of the mouse and said, "It's really difficult to identify the suspicious vehicle at this location."

Jiang Yuan's tone was somewhat disappointing. With his skills, as long as the surveillance picture was captured, even if it was slightly blurry, he could use image enhancement to restore it.

In addition, LV3's technical defense monitoring system is a skill that understands the monitoring system from the bottom. He can build a complete monitoring system, so using it is naturally not a problem.

However, all these skills are extremely useful, but without suspicious vehicles, no matter how good the skills are, they cannot be used.

"Looking at it this way, the murderer may be relatively familiar with the nearby environment. He must be able to avoid surveillance intersections, at least to this extent." Liu Jinghui frowned again as he spoke.

Mu Zhiyang whispered from the side: "Well...didn't you say before that an acquaintance committed the crime?"

"The crime committed by an acquaintance is based on common sense and there is no evidence to support it." Liu Jinghui shook his head.

Mu Zhiyang also frowned: "Don't reasoning require evidence?"

"Who said reasoning doesn't require evidence!" When Liu Jinghui heard this, his temper was instantly ignited. He rolled up his sleeves and said, "Wait a minute, let me explain this issue to you..."

"Liu Chu..." Jiang Yuan quickly interrupted and said, "Go back and eat."

"If we can't solve the case, we can't sit down and have a good meal." Liu Jinghui sighed and said, "Let's go back and get some instant noodles or something."

"No, there are plenty of opportunities to eat instant noodles. If you want to eat noodles... I'll give you a call." Jiang Yuan's mood was relatively stable, and the frustration of not being able to make a breakthrough in the case passed quickly. He quickly made a phone call and came back. He said, "I'll have someone bring a pot of noodles to the police station. Let's eat some together. By the way, does Liu Chu want to go home for dinner?"

Liu Jinghui's mouth twitched twice, and then he looked at the sky outside and said, "What can I eat at this time? Just treat it as a business trip."

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

Jiang Yuan asked someone to send over the cooked beef soup and beef. The chef took the noodles directly from the noodle press, threw them into boiling water to cook, then poured the soup, put the beef, and then threw in chopped green onions and coriander, and that was considered to be the completion of this bowl of beef noodles that were not beef noodles.

There is actually only one key point in this dinner. The soup is a thick soup made from a large amount of beef and beef bones, and then more beef is added.

A bowl of noodles, half a bowl of soup, and one-third of a bowl of beef. It doesn't matter how the remaining noodles taste, how they are seasoned, and how the side dishes are.

Most of the police officers in the task force are young and strong. When eating noodles, they eat one bowl after another. The three chefs in the canteen, one pressed the noodles, and two cooked and scooped the noodles, and they barely served them.

Jiang Yuan ate three bowls of noodles heartily before pushing the bowl away and taking a break.

At this time, Wan Baoming hurried over with a file bag under his arm.

"Let me show you the new report from the physical and chemical laboratory." Wan Baoming was not joking, which meant that this was a serious matter.

"Change the table." Jiang Yuan stood up directly, moved 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 measurements. This kind of laboratory sounds very high-end, but in fact, it is the same as the toxicology laboratory, which can only read or recognize familiar compounds. Therefore, if it is an ordinary case, the physical and chemical laboratory will do routine measurements and then give a conclusion.

However, when encountering major cases or "senior police officers" like Jiang Yuan, the physical and chemical laboratory will be forced to expand its inspection items. After the common compounds are tested, the uncommon ones must be tested continuously, so that the experimenter has been busy until the evening.

And the physical and chemical report that Wan Baoming brought over is the result of his busy work so far.

The first page in the file bag is the most important achievement of the physical and chemical laboratory. A red line is the hard work of the physical and chemical laboratory.

"Cefoperazone sodium and tazobactam sodium?" Jiang Yuan read it and reacted quickly. This thing is for injection, and the treatment effect is very good. The bacteria it can kill are not only useful on living people, but also on dead people. If the amount injected is large enough, the post-mortem residue can definitely reduce the post-mortem corruption and act as a preservative.
