Chapter 654 The Second Case of Zhengguang

Jiang Yuan selected the case of corpses abandoned in the sewer of Bandung Garden after reviewing dozens of cases.

Jiang Yuan first paid attention to this case because he noticed a large number of photos and video materials, indicating that the surveillance in the area was very intensive.

For urban cases, backlogged cases will be much easier to detect if there is surveillance. Even if it is a murder case that was not solved back then, if surveillance is pulled out now, at least for this part, it will be fresh.

While continuing to browse the photos, Jiang Yuan discovered some clues, and finally decided to choose this case as the second case of the backlogged case team in the Zhengguang Bureau.

After all, he was working in the capital. There were so many great people around him, and he didn't know how many pairs of eyes were looking at him. Jiang Yuan felt that he needed a clean murder case.

The Bloody Suit Case is relatively complex, and the process of handling the case is also unsatisfactory. When placed in a Cantonese-style morning tea, it can only be regarded as excessive at best, not beautiful.

Solving a case is often like fighting a war. If you win, you don't need to emphasize how strong your opponent is. Your opponents are all defeated anyway. If you lose, you don't need to emphasize how strong your opponent is. You will lose anyway.

Whether you win well or not often depends on the battle loss ratio. No matter how elite the troops you lead, if you win against twice as many rabble, you will win with less. On the contrary, if you lose regardless of the reason, you will be a fool. Zhang Han in the late Qin Dynasty and Liu Xiu in the late Han Dynasty were both like this.

Solving a case also depends on the battle-loss ratio. The losses and expenses are on the one hand, and the time consumed is also very important.

Of course, normal white-shirted people would not have such thoughts. Most criminal police teams would be happy if they could solve the case. This is just Jiang Yuan's self-cultivation.

meeting room.

Wang Chuanxing and Mu Zhiyang placed the photos all over the table and arranged them neatly.

This is Jiang Yuan's traditional craft. He can see too many things from the photos. Even now, he can't describe what is needed to his subordinates. He just puts it on display.

Liu Stinky Sheng was lying in the corner with a resentful look. He was the main investigator of the case of corpses abandoned in the sewer of Bandung Garden, and he also knew the most about the case. However, at this moment, he was so pickled that he just wanted to be quiet. Stay for a while.

Because the person who wants to explore the sewers again may still be him, and even if every cell of Comrade Liu Sheng is familiar with the smell, the stench of the sewers and the stench of the garbage mountain are not the same stench.

"Liu Da." Jiang Yuan shouted, holding a photo in his hand.

"Just call me Lao Liu." Liu Sheng replied modestly. Not wanting to leave the scene was just a thought, but his body quickly moved to Jiang Yuan's side.

Jiang Yuan covered his nose, coughed twice in embarrassment, and said, "Let's talk about the case first."

"Okay. You say it." Liu Sheng took two steps back obediently.

Jiang Yuan directly handed the photo to Liu Sheng, and then said: "Look here, the photo of the deceased at the scene. When your task force analyzed the case, did you think it was possible to move the body or rob and kill? Here I There are different opinions.”

Liu Sheng panicked at first, then calmed down in an instant.

I feel flustered because something went wrong. Although it is normal to make mistakes at work, he made a mistake in detecting a murder case and was found out... However, it was Jiang Yuan who corrected the mistake, and Liu Sheng felt that everything was fine again.

With Jiang Yuan's current situation, maybe there are still people in the bureau who are gossiping, but when it comes to technology, when it comes to formal occasions, whether it is a meeting or an internal discussion, no one dares to turn a deaf ear to Jiang Yuan's judgment, or turn a blind eye to it. .

In other words, Jiang Yuan's correction is not important. At least, he will not be criticized for it.

Liu Sheng composed himself, looked at the photo again, frowned, and then asked angrily: "You need to give me more instructions."

"You see, the deceased's left hand was grasping the water plants on the side of the sewer. His left hand looked relatively loose, but this was actually due to the relaxation of muscles after death. In addition, the neck of the deceased was also injured at the scene. Tangled with garbage bags, this is more likely to be the first scene." Jiang Yuan looked at this photo for a long time, and now he can describe it without looking at it.

Liu Sheng became even more confused and said: "Shouldn't the grasping action after death be made tighter and tighter?"

"Not necessarily. It has something to do with the environment he was in and the posture he was in when he died." Jiang Yuan paused and then said: "When you found the body, the body had actually ended rigor mortis for a long time, so it just looked relaxed. That’s all, he most likely held onto this bunch of grass tightly before he died.”

Liu Sheng nodded as if he understood. He was not a forensic doctor and was incapable of arguing with Jiang Yuan. He didn't need to argue, he just listened.

Jiang Yuan picked up another photo at this time, handed it to Liu Sheng, and said: "This is also the second point I want to make, the determination of the time of death. The time of death you determined at that time was 2 to 5 days after death, which is too conservative. Dead. He has been dead for at least 7 days."

To this day, no matter how many ways there are to judge the time of death, it is still an empirical science. In this regard, Jiang Yuan has a lot of room to play.

Liu Sheng heard an "ah" sound and hurriedly said: "The body was found on February 18th. On February 12th, someone even said they saw him."

Their medical examiner will give a judgment of 2 to 5 days after death, which is also related to this. As for using elements other than autopsy to determine the time of death... this method is definitely correct. It is a very common criminal investigation practice to rely on things like broken watches to determine the time of death.

Jiang Yuan didn't dwell on this with Liu Sheng. He only looked down at the photo twice and said, "Then I suggest you bring this last witness over and ask questions."

Liu Sheng was stunned for a moment. He looked closely at Jiang Yuan's serious expression, and his face suddenly darkened: "This bitch lied to us?"

"Who is he?" Jiang Yuan motioned to Wang Chuanxing and others to look through the transcript.

Under normal circumstances, if ordinary people face the criminal police and are not asked to reveal their underwear, they are considered to have excellent psychological quality. If you really committed something, or if you feel guilty, it will be easily exposed by the criminal police.

In other words, those who can make false confessions are either under extraordinary circumstances or are not ordinary people.

Liu Sheng didn't need Wang Chuanxing to look for the transcript, so he said: "He is the owner of the mahjong parlor on the corner, and his home is in Bandung Garden. He said that on February 12, the deceased met him in the community and said hello. I remember that the deceased should be his old client, and the two of them did not have many disputes over their interests, at most they were over gambling debts."

"Then ask first. Let's check the surveillance videos before February 11th, especially until February 9th." Jiang Yuan chose Wanlong Garden because there were so many video recordings in the information.

Because the previous time of death was determined to be after February 12, no one took a serious look at the videos before February 11, which is what Jiang Yuan believed to be the real time of death.

This is also a drawback of too many videos. Just like the problem faced by big data, when there is too much information, screening becomes a problem.

Liu Sheng responded with a solemn expression, went out without stopping, and led the people straight to the mahjong parlor near Wanlong Garden.

It was one thing that the case could not be solved, but being fooled by the murderer in front of him was really hard for Liu Sheng to accept.

Tang Jia, who was next to him, watched Liu Sheng leave. He held his cell phone and hurried over, saying: "Captain Jiang, Political Commissar Huang has already boarded the plane."

"Coming to the capital?" Jiang Yuan was a little surprised: "Are you in such a hurry?"

"He didn't expect your second case to be completed so quickly." Tang Jia felt a little funny and a little excited. He turned to look at the conference room of the Zhengguang Bureau, and suddenly felt hungry, as if he had entered a cafeteria.
