Chapter 164
Rumble!
A bolt of lightning struck down from the sky, followed by the sound of thunder.

The sunny weather suddenly turned into hell.

Jiang Yuan ran all the way back to the building of the Criminal Police Brigade with the USB flash drive in his mouth, and Liu Jinghui followed closely.

"I actually have earphones." Jiang Yuan sighed, and led Liu Jinghui back to the office.

wow wow.

It was pouring rain, and it fell as soon as it was said, hitting the glass and making a crackling sound.

Jiang Yuan quickly closed the window and turned it on.

Liu Jinghui found a seat and sat down on his own, as if he was a guest, watching Jiang Yuan busy, feeling very safe in his heart.

"Tea or coffee?" Jiang Yuan closed the window and asked Liu Jinghui politely.

"Tea." Liu Jinghui thought about it.

Jiang Yuan fished out a bottle of "tea π" from under the desk and put it in front of Liu Jinghui.

Liu Jinghui, 40, could hardly hold back.

But when he raised his head and saw that Jiang Yuan had already looked at the case in the USB flash drive, he had to suppress his mood again.

"This is a case from last month. It was in a residential area of ​​Yunchang City. The deceased was a 45-year-old woman. She was an accountant for the "Yunchang Evening News". She usually had a hobby of buying gold and silver jewelry. It is suspected to be a burglary or an escalation of the robbery." Fatal." Liu Jinghui not only introduced the case, but also hinted at the complexity of the case in just two sentences.

Cases involving the media must be handled with extreme care.

The deceased was an accountant in the unit, so he had to be more careful.

"Multiple fingerprints were extracted at the crime scene, but there were no blood fingerprints, and none of them could be linked to the case itself. In addition, there were bloody footprints at the scene, which were seen by two experts from the provincial department, and the conclusions they gave were also unsuccessful. Lock down the murderer."

Liu Jinghui continued to introduce.

The case is obviously very difficult, but Liu Jinghui is not very anxious.

He has always done difficult cases.

However, any cases that can find suitable fingerprints, potential DNA, or footprints, murder weapons, etc., can be located through technology, will not fall into Liu Jinghui's hands.

Only Liu Jinghui in Shannan Province can solve cases purely by reasoning.

Of course, reasoning does not mean that technical support is not needed.

Liu Jinghui's idea was quite simple, and he said: "I think the level of personnel doing on-site investigation in Yunchang City is relatively limited. There are a lot of bloody footprints at the scene, but there is no blood fingerprint left, and no clothing fibers or traces were found. For other physical evidence, I want to ask you to look at it again."

The physical evidence found, including the unknown fingerprints, footprints, and the blood itself, have all been seen by experts from the provincial department.

However, these evidences were all extracted from the current survey in Yunchang City.

From Liu Jinghui's point of view, if the existing evidence cannot be proved, it is better to simply re-examine the crime scene.

He also hopes to reconstruct his own vision of the case by examining the crime scene.

Compared with fingerprints and other things, Liu Jinghui still had a fresh memory of Jiang Yuan's level of on-site investigation and trusted him quite a bit.

In fact, Jiang Yuan's crime scene investigation ability is really better than fingerprint identification - the criminal police in Ningtai County can't see it, and Liu Jinghui actually can't see it, but he has seen it before, vaguely If you are confused, you will have a more correct understanding.

Jiang Yuan was on the computer, flipping through the photos one by one, without saying a word.

Liu Jinghui looked slightly displeased, and even said a few words, before Jiang Yuan could say anything, Liu Jinghui claimed to be a master of reasoning, and when he turned his mind, he guessed something, and said:
"Yes, I came here by the way this time, but I didn't want to bother you. You know. Because you are on a business trip, you have been engaged in several cases in a row recently, so I just wanted to bring other investigations. Go and have a look."

"It just so happened that people from the ministry came over and said they were going to Ningtai County, so I followed here on purpose. I believe in your on-site investigation ability. If I didn't believe it, I wouldn't have rushed over."

"By the way, when I took this case two days ago, you were still working on a murder case. Who knows when you will solve the case. Yunchang City can't wait."

Jiang Yuan waved his hand, said "En" again, and said, "I know. You think too much."

Liu Jinghui's eyes lighted up, thinking too much, usually people who say that blame you for not thinking about it...

"Ahem." Liu Jinghui changed his angle and said, "Why don't you take a day off first, because it's raining today anyway, so you can't leave. We'll talk about it tomorrow."

"It's okay, I was resting yesterday." Jiang Yuan waved his hand again.

Liu Jinghui reasoned in his mind, and explained: "I understand, I may have come in a hurry, and I didn't call beforehand..."

"Is the scene well protected?" Jiang Yuan interrupted Liu Jinghui's thoughts.

Liu Jinghui paused for two seconds before continuing: "The crime scenes are all indoors, mainly the victim's master bedroom, so there won't be any wind and rain."

"If possible, it's best to seal up the crime scene first. Let people not enter or leave for the time being." Jiang Yuan said.

Liu Jinghui turned around and asked, "Do you have an idea? What idea?"

"I have to look at the pictures of the scene again, study and study, and then come to a conclusion." Jiang Yuan emphasized: "When I have an idea, I will reconsider the problem of the crime scene. I will ask people not to go there for the next two days. Protect the scene..."

"Don't engage in metaphysics." Liu Jinghui was unhappy, and deliberately said: "You watch TV dramas and movies, the technicians who play tricks often die before the results come out."

Jiang Yuan glanced at Liu Jinghui, and said slowly: "I think there is something wrong with the footprints, I'll think about it when I go back."

Liu Jinghui couldn't help but said, "I showed the footprints to Lao Zuo. What do you think is the problem?"

"The previous experts probably just looked at the pictures statically." Jiang Yuan asked Liu Jinghui back.

Liu Jinghui thought about it for a moment, then nodded lightly: "It's about the same. What do you think of the picture of the footprints?"

"You can think about it comprehensively. I don't have a definite conclusion right now." Jiang Yuan didn't want to be long-winded. He got up and said, "Liu Chu, why don't you rest first, and I'll give you the result tomorrow."

"This... alright." Liu Jinghui had no choice but to remain silent.

However, it was raining outside, and Liu Jinghui had nowhere to go.

Jiang Yuan also glanced out the window, sat back on the chair by himself, and silently looked at the pictures on the USB drive.

Liu Jinghui stuffed the photos taken by local surveys into the USB flash drive. In terms of the number of photos alone, there are a lot of them.

Jiang Yuan looked and saw that the rain outside had stopped.

The air after clearing is extraordinarily sweet.

Jiang Yuan got up and opened the window, took two breaths of fresh air, turned around, Liu Jinghui stood up as if he had been awakened.

When Liu Jinghui didn't want to talk, Jiang Yuan shook his head and said, "Liu Chu, I have a guess."

"Oh, tell me." Liu Jinghui replied hastily.

"I think some of the bloody footprints at the scene of the crime were man-made." Jiang Yuan replied.

Liu Jinghui frowned: "Man-made?"

"Looking at it as a whole, the footprints here are the most obvious. It looks like the footprints came in, but the suspect actually walked out backwards." Jiang Yuan clicked on the picture on the screen, and his tone gradually became affirmative.

The footprints of different centers of gravity are also different.But static footprints can be interpreted in many ways.It is necessary to combine the scene and gait to make a definite judgment.

The main idea is that the gait of walking backwards must be relatively small.

Liu Jinghui never cared about the technical details, but quickly pushed it down: "Falsifying the crime scene shows that the suspect really has anti-reconnaissance capabilities. And if he wants to get rid of the crime by forging the scene, it shows that he is easy to be suspected. The main suspect..."

Seeing that Liu Jinghui had entered a state of reasoning, Jiang Yuan simply watched in silence.

Liu Jinghui was getting more and more excited, getting more and more excited.

After a while, Liu Jinghui turned his head, looked at Jiang Yuan and sighed: "If the footprints are really fake, it is likely that an acquaintance committed the crime, and the biggest suspect is the husband of the deceased. If it is true, the case It broke."

Liu Jinghui looked at Jiang Yuan enthusiastically.
