Chapter 163: Destroyed in one picture
Boom!
A bolt of lightning struck down from the sky, followed by the sound of thunder. The sunny weather suddenly turned into the underworld.
Jiang Yuan carried the USB drive and ran all the way back to the criminal police brigade building, with Liu Jinghui following closely. "I actually have headphones." Jiang Yuan sighed and led Liu Jinghui back to the office. Wow.
The rain was pouring down at once, hitting the glass and making a crackling sound. Jiang Yuan quickly closed the window and turned on the phone.
Liu Jinghui took care of himself and found a seat to sit down, as if he were a guest. Seeing Jiang Yuan busy, he felt a sense of security in his heart.
"Tea or coffee?" Jiang Yuan closed the window and asked Liu Jinghui politely. "Tea." Liu Jinghui thought about it.
Jiang Yuan took out a bottle of "tea π" from under his desk and placed it in front of Liu Jinghui. Liu Jinghui, 40, almost couldn't hold it back.
But when he raised his head and saw that Jiang Yuan had already read the case in the USB flash drive, he had to suppress his mood.
"This was a case last month in a residential area in Yunchang City. The deceased woman was 45 years old. She was the accountant of "Yunchang Evening News" and she usually liked to buy gold and silver jewelry. It is suspected to be a burglary or robbery. Fatal." Liu Jinghui only introduced the facts of the case in two sentences, but also hinted at the complexity of the case.
Cases involving the media must be handled with extreme caution. The deceased was also the accountant of the company, so he had to be extra cautious.
"Multiple fingerprints were extracted from the crime scene, but there were no blood fingerprints, and they could not be linked to the case itself. In addition, there were blood footprints at the scene. They were shown to two experts from the provincial department, and the conclusions they gave were inconclusive. Find the murderer."
Liu Jinghui continued to introduce.
The case is obviously very difficult, but Liu Jinghui is not very anxious. He has always dealt with difficult cases.
Any case where suitable fingerprints, potential DNA, or footprints, murder weapons, etc. can be found and can be located through technology will not fall into Liu Jinghui's hands.
Liu Jinghui is the only one in Shannan Province who solves crimes 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 the on-site investigation personnel in Yunchang City is relatively limited. There were a large number of bloody footprints at the site, but not a single bloody fingerprint was left, and no clothing fibers or clothing fibers were found. I want to ask you to take a look at the other physical evidence."
The physical evidence found, including fingerprints and footprints from unknown sources, as well as the blood stains themselves, have been reviewed by experts from the provincial department.
However, these evidences were all extracted from on-site surveys in Yunchang City.
From Liu Jinghui's point of view, if the existing evidence cannot be used, it would be better to re-investigate the crime scene. He also hopes to reconstruct his vision of the case by investigating the crime scene.
Compared with fingerprints and other things, Liu Jinghui still has a clear memory of Jiang Yuan's on-site investigation level and quite trusts him.
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 can't actually see it, but he has seen it before, and it's vague. will have a more correct understanding.
Jiang Yuan was on the computer, looking through the photos one by one without saying a word.
Liu Jinghui looked a little unhappy and even said a few words. Before Jiang Yuan could say a word, Liu Jinghui claimed to be an expert in reasoning. With a quick thought, he guessed something and said:
"Yes, I came here by the way this time, but I didn't want to trouble you. You know. Because I have to go on a business trip, and you have been involved in several cases in a row recently, so I thought of bringing other investigators with me. Go over and take a look.”
"It just happened that someone from the ministry came and said they were coming to Ningtai County, so I came here specially. I believe in your ability to conduct on-site inspections. If I didn't believe it, I wouldn't have rushed here."
"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 any longer."
Jiang Yuan waved his hand and said "en" again, "I know. You are thinking too much."
Liu Jinghui's eyes lit up. What are you thinking about? People who say this usually blame you for not thinking of it earlier...
"Ahem." Liu Jinghui changed his angle and said, "If you don't take a day off first, it's going to rain anyway and we won't be able to walk. Let's wait until tomorrow."
"It's okay, I was already 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 didn't call in advance..."
"Is the scene protected well?" 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. They will not be affected by wind or rain."
"If possible, it's best to seal up the crime scene first. No one will be allowed in or out for the time being," Jiang Yuandao said. Liu Jinghui changed his mind and asked, "Do you have an idea? What idea?"
"I have to look at the pictures from the scene again and study them before I can draw a conclusion." Jiang Yuan emphasized: "When I have an idea, I will reconsider the crime scene issue and ask people not to go there for the next two days. Protect the scene well..."
"Don't engage in metaphysics." Liu Jinghui was unhappy and said deliberately: "You see in TV series and movies, technicians who engage in mystical tricks often die before the results are available."
Jiang Yuan glanced at Liu Jinghui and said slowly: "I think there is something wrong with the footprints. I will 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 wrong?"
"The experts before probably just looked at the pictures statically." Jiang Yuan asked Liu Jinghui in return. Liu Jinghui thought about it for a moment and nodded lightly: "Absolutely. How else do you want to see the pictures of the footprints?"
"We can think about it comprehensively. I don't have a definite conclusion now." After Jiang Yuan said this, he didn't want to be verbose. He stood up and said: "Liu Chu, if you don't rest first, I will give you the results tomorrow."
"This... okay." 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 his chair, and silently looked at the pictures on the USB flash drive.
Liu Jinghui stuffed all the photos taken during the local survey into the USB flash drive. In terms of the number of pictures alone, there are a lot of them.
As Jiang Yuan watched, the rain outside stopped. The air after it cleared up was especially sweet.
Jiang Yuan stood up and opened the window, taking a few breaths of fresh air. When he turned around, Liu Jinghui stood up as if he had been awakened.
On the rare occasion when Liu Jinghui didn't want to talk, Jiang Yuan shook his head and said proactively: "Liu Chu, I have a guess." "Oh, tell me." Liu Jinghui replied quickly.
"I think part of the bloody footprints at the crime scene were man-made." Jiang Yuan replied. Liu Jinghui frowned: "Man-made?"
"Look at this as a whole. The footprints here are the most obvious. They look like the footprints coming in, but they are actually the suspect walking out backwards." Jiang Yuan clicked on the picture on the screen and his tone gradually became more certain.
The footprints of different centers of gravity are also different. But static footprints can have many interpretations. It is necessary to combine the scene and gait to make a definite judgment.
The main idea is that when walking backwards, the stride length must be small.
Liu Jinghui always ignored the technical details and just pushed it quickly: "Forging the crime scene shows that the suspect really has anti-reconnaissance capabilities. And that he wants to use the method of forging the scene to get away with it shows that he is easy to be suspected, and he is probably The main object of suspicion..."
Jiang Yuan saw that Liu Jinghui had entered a reasoning state, so he simply watched without saying a word. But Liu Jinghui became more and more excited, more and more excited.
After a while, Liu Jinghui turned around, looked at Jiang Yuan and sighed: "If the footprints are really disguised, then it is likely that an acquaintance committed the crime, and the biggest suspect is the deceased's husband. If this is indeed the case, the case It’s broken.”
Liu Jinghui looked at Jiang Yuan with passionate eyes.
