Chapter 654 Zhengguang Case 2

Chapter 654 The second case of Zhengguang

Jiang Yuan selected the Wanlong Garden Sewer Abandoned Corpse Case after reviewing dozens of cases.

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

For urban cases, if there is monitoring, the backlog of cases will be much easier to solve.Even if it was a murder case that was not solved back then, now that the monitoring is pulled out, at least in terms of this part, it is at least fresh.

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

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

The complexity of the bloody coat case was high, and the process of handling the case was not satisfactory. Putting it in the Cantonese style morning tea, it can only be regarded as super, 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. Anyway, your opponent is defeated. If you lose, you don’t need to emphasize how strong your opponent is. You lose anyway.

Whether you win well or not depends on the ratio of battle losses in many cases. No matter how elite the troops you lead, if you win against a mob that is doubling in size, you will win more with less.Zhang Han in the late Qin Dynasty and Liu Xiu in the late Han Dynasty were all like this.

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

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

meeting room.

Wang Chuanxing and Mu Zhiyang placed 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. Now, he has no way to describe what is needed to his subordinates. Just put what is there.

Liu·Stink·Cheng was lying in the corner with resentful eyes. He was the main investigator of the Wanlong Garden Sewer Abandoned Corpse Case, and he knew the most about the case. stay for a while.

Because the person who will check the sewer later may be him, and even if every cell of Comrade Liu Sheng is familiar with the smell, the smell of the sewer and the smell of the garbage mountain are not the same smell.

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

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

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

"Okay. Tell me." 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 at that time. I saw that when your special case team analyzed the case, they thought there was a possibility of moving the corpse or robbing and murdering? Here I am There are differences of opinion."

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

Feeling flustered because something went wrong.Although it is normal to make mistakes at work, he was caught out when he made a mistake in the detection of a murder case... However, it was Jiang Yuan who corrected the mistake, and Liu Sheng felt that it was all right again.

As far as Jiang Yuan's current state is concerned, there may still be some people in the bureau who talk badly, but when it comes to technology, no one dares to turn a deaf ear to Jiang Yuan's judgment, or ignore it when it comes to formal occasions, whether it is a meeting or an internal discussion .

In other words, Jiang Yuan's error correction doesn't matter, at least, he won't be blamed for it.

Liu Sheng collected himself, looked at the photo again, frowned, and then asked kindly: "You need to give me some instructions."

"Look, the deceased's left hand was holding the water plants on the side of the sewer. His left hand looked loose, but it was actually loose because of the tense muscles after death. In addition, the neck of the deceased was also taken by the scene. The garbage bags are entangled, and this is more likely to be the first scene." Jiang Yuan looked at this photo for a while, and now he can describe it without looking at it.

Liu Sheng was even more puzzled, and said, "Shouldn't the grip after death be held tighter and tighter?"

"Not necessarily, it has something to do with his environment and his posture when he died." Jiang Yuan paused, and then said: "When you found the corpse, the corpse had actually been out of rigor for a long time, so it just seemed relaxed That's all, there is a high probability that he was holding on to this bunch of grass tightly before he died."

Liu Sheng nodded half-understood. He is not a forensic doctor either, so he is incapable of arguing with Jiang Yuan.He doesn't need to argue, just listen.

At this time, Jiang Yuan picked up another photo, handed it to Liu Sheng, and said, "This is also the second point I want to talk about, the determination of the time of death. You determined the time of death at 2 to 5 days after death, which is too conservative. Dead. Dead for at least 7 days.”

To this day, regardless of how many ways and methods 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.

Unconsciously, Liu Sheng let out an "ah" and hurriedly said, "The body was discovered on February 2, and on February 18, someone claimed to have seen him."

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

Jiang Yuan didn't bother with Liu Sheng, just looked down at the photo, and said: "Then I suggest you bring this last witness over here, and then ask carefully."

Liu Sheng was taken aback for a moment, looked at Jiang Yuan's serious expression, and then his face darkened in an instant: "This bastard lied to us?"

"Who is it?" Jiang Yuan signaled Wang Chuanxing and others to go through the transcript.

Under normal circumstances, ordinary people are considered to have excellent psychological quality if they are not asked to reveal their underwear when facing criminal police.If he really did something wrong, or if he had a guilty conscience, it would be easy for the criminal police to expose him.

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

Liu Sheng didn't need Wang Chuanxing to look for transcripts, and said by himself: "It's the owner of the mahjong parlor on the corner, and his home is in Wanlong Garden. It is said that on February 2, 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 didn't have too many conflicts of interest, at most it was about gambling debts."

"Then ask first. Let's check the surveillance video before February 2, especially until February 11." Jiang Yuan chose Wanlong Garden because there are so many videos in the data.

Because the previous death time was determined to be after February 2th, no one took a serious look at the video before February 12th, that is, before and after Jiang Yuan believed the real time of death.

This is also a disadvantage of too many videos, just like the problem faced by big data. When there is too much information, screening becomes a problem.

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

It's one thing not to be able to solve the case, but being fooled by the murderer face to face is really hard for Liu Sheng to accept.

Tang Jia, who was standing next to him, watched Liu Sheng leave, then squeezed his phone, hurried over, and said, "Captain Jiang, Political Commissar Huang has already boarded the plane."

"Come to the capital?" Jiang Yuan was slightly surprised: "In such a hurry?"

"He didn't expect your second case to be done so quickly." Tang Jia felt a little amused and a little excited, turned his head to look at the conference room of Zhengguang Bureau, and suddenly felt hungry and entered the cafeteria.
