God-level Crime-solving Group

What is the purpose of the murderer to leave this scene?

Su Yang couldn't help but have a lot of questions in his mind.

"Is this a technical difficulty?" After thinking for a while, Su Yang looked at Jiang Judo.

Jiang Rou lowered her head and thought about it carefully, then raised her head and said, "Actually, it's not difficult to do this, it's just a bit complicated and requires certain materials to do this."

Zhu Lan couldn't help but asked: "How can this be done? Can we use this to lock the murderer?".

Chapter 1172 Extra...!

The vision of the corpse somewhat puzzled Su Yang. A person who was burned to death had frostbite in his body. This strange scene rarely appeared in usual cases.

The last time such a strange phenomenon occurred was the snowy night case in Haicheng, but all the girls in a dormitory froze to death on a snowy day. Later investigations revealed that they were locked in a research room.

This case is different. The murderer was burned to death by a very common fire, but it is strange that the deceased has traces of frostbite on his body.

And Jiang Rou said that this is not a technical difficulty. If she wanted to do it, she could do it, but she couldn't do such a thing.

Jiang Rou explained: "Injecting liquid nitrogen into the deceased, or allowing the deceased to drink liquid nitrogen, will cause frostbite in the body of the deceased. These two things are difficult to implement, especially for the deceased to drink it. Liquid nitrogen, the possibility is very low, so I suspect that the murderer injected liquid nitrogen into the deceased."

Liquid nitrogen, as the name suggests, is liquefied nitrogen, colorless, odorless, non-flammable, non-corrosive, and the main component of the atmosphere is nitrogen.

However, liquid nitrogen will absorb a lot of heat when it is vaporized, and if people touch it, frostbite will occur.

However, things like liquid nitrogen are not common, and they all appear in industry.

380 "In addition to liquid nitrogen, dry ice is also an industrial product that absorbs heat when it evaporates, but relatively speaking, liquid nitrogen is more useful." Jiang Rou said again.

Su Yang thought for a while and said, "That is to say, the murderer was injecting some industrial product into the deceased, causing signs of frostbite in the deceased's body, and then burning the deceased to death?"

Jiang Rou nodded and said, "It should be like this now."

Su Yang turned his head and glanced at the corpse, and there was a look of thought in his eyes. Zhu Lan couldn't bear to look at the corpse, so he turned his eyes to Su Yang who was thinking.

After staying in the forensic identification center for a while, Su Yang walked towards the physical evidence department.

Zhu Lan naturally followed behind Su Yang.

In the Physical Evidence Section, Su Yang found a policeman and asked, "Where is the physical evidence at the scene of the burning of the little girl in the suburbs?"

The policeman turned around and took some things over and said, "Consultant Su, these were found at the scene, and we also took out all the things in the schoolbag."

On the table, a cartoon book is packaged in the evidence bag, and in other evidence bags, there are some books and stationery, all of which the little girl needs to go to school (bfcb).

"Is that all there is to it?"

"Yes, Consultant Su, no extra items were found at the scene. We inspected these items and found no valuable clues."

Su Yang took a look and left. These physical evidences were all used by the little girl to go to school, and had little investigative value.

After returning to the task force's office, Yan Rui also came to the city bureau and was looking at the file on Zhu Lan's desk carefully.

After seeing Su Yang and the two coming in, he put down the file in his hand, got up and said hello, "Team leader."

Su Yang waved his hand, indicating that there is no need to be more polite.

Seeing Su Yang turning around and walking into the independent office, Yan Rui asked, "Consultant Su, where did Team Zhang go? Why didn't you see him?"

"Team Zhang?" Su Yang stopped, thinking of some things that he had arranged before coming to Fengdu, Zhang Xing should be busy with that, after all, a tail fell behind, which is still very unpleasant.

Seeing that Su Yang ignored him, Yan Rui scratched his head in confusion.

Seeing that Su Yang ignored him, Yan Rui scratched his head in confusion.

I wanted to ask Zhu Lan again, but I didn't expect that Zhu Lan didn't even look at Yan Rui, and walked directly into Su Yang's office.

"Strange." Yan Rui stared suspiciously at the door of Su Yang's office, then turned to look at the file on the table, his expression became solemn again.

In the independent office, Zhu Lan sat opposite Su Yang and asked with a stiff face, "Team leader, what do you think of the vision of the corpse?"

Su Yang didn't answer her question, but stared at her face and said, "Did someone say that your face is very ugly?"

Zhu Lan was stunned, as if he understood something, and said a little annoyed: "What does the team leader mean?"

"It's not interesting." Su Yang waved his hand and didn't say much, but looked at Zhu Lan and said, "What do you think about the vision of the corpse?"

Zhu Lan was stunned again, didn't he ask the team leader himself?How come back.

But she still answered honestly: "When I was in the training class, a teacher said that you said that all the visions in the case have some meaning, unless the murderer is confused."

"Yeah." Su Yang nodded. It seemed that this sentence was mentioned in the notebook.

Zhu Lan added: "But there are a lot of mistakes. The murderer in any case is high on clean and neat means of killing, so the cloth maze is used to cover up something, but it is such a complicated method to inject industrial products into the deceased. , it must not be a mystery."

"So what?" Su Yang asked again.

Zhu Lan thought for a while and said, "So there must be some reason for the murderer to do this. This reason may be related to a certain idea in the murderer's mind, or even the motive of the murder."

"That's right." Su Yang nodded.

Zhu Lan's already stiff face became even more stiff. He was here to ask the team leader's views on the case, so why did he end up talking all by himself?

"Girls have to laugh more, so they will be more beautiful." Su Yang said without end.

Zhu Lan's face was stunned, or in other words, it was stunned from beginning to end.
