National Forensic Doctor

Liu Jinghui took his brains and went to the detective 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 criminal police officers from the Picture Detective Brigade looked like they were well-educated, and some of them could change the angle 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 monitored 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, I will 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 twitched the corner of his mouth twice, then looked at the sky outside and said, "When I go home at this time, I can eat whatever I want, just treat it as if I'm on a business trip."

Jiang Yuan and others were really on a business trip and had no place to go. A group of people gathered in the canteen of the Criminal Investigation Detachment, waiting for the chef.

Jiang Yuan had someone deliver cooked beef soup and beef. The chef comes out directly from the noodle press, throws it into boiling water and cooks it, then pours soup, adds beef, and then throws in some chopped green onion and coriander. This is a bowl of beef noodles that is not beef noodles.

There is actually only one key point to this dinner. The soup is a thick soup made with a lot of beef and beef bones, and then more beef.

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

Most of the police officers on the task force were young and strong, and they ate bowl after bowl of noodles. One of the three chefs in the canteen made the noodles, and two others cooked and scooped them out. .

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 document 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 serious business.

"Change a table." Jiang Yuan stood up directly, moved to a clean table next to him, then opened the document bag and started reading.

The physical and chemical laboratory is mainly a place where physical and chemical measurements are performed. This kind of laboratory sounds very high-end, but in fact, like the toxicology laboratory, it can only read out 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 a major case or a "senior police officer" like Jiang Yuan, the physical and chemical laboratory's inspection items are forced to expand. After the common compounds have been tested, the uncommon ones must continue to be tested, so as to As for the experimenters, they were busy until the evening.

The physical and chemical report that Wanbaoming brought over is the result of the busy work so far.

The first page in the folder is the main achievement of the physical and chemical laboratory. A red line is the self-described hard work of the physical and chemical laboratory.

"Cefoperazone sodium and tazobactam sodium?" Jiang Yuan read it once and reacted quickly. This thing is for injection, and the therapeutic effect is excellent. The bacteria it can kill are not only useful on living people, but also on dead people. If the amount of injection is large enough, the residue after death can definitely reduce the risk of death after death. Corruption, acting as a preservative.
