It's a process of being frozen first and then thawing, right?"

Song Dongxi nodded and said: "Actually, there are many points to prove this inference. For example, regarding rigor mortis, you said you felt that his body seemed hard but not hard. In fact, it was a state where rigor mortis had just begun to form, and freezing can delay the formation of rigor mortis.

The formation of stiffness and cadaveric plaques are the same. Furthermore, you said that his eyes were half-opened. This is also because the contraction of muscles due to low temperature caused the eyelids to be stretched open by the eyeballs. Therefore, the old beggar was removed from the morgue.

The hypothesis that the body was moved to a small dark room should be established."

Zhang Liang nodded, but did not express any further opinions. Instead, he motioned to Song Dongxi to continue: "The second point is that we will talk about the cause of his death. There is no doubt that the old beggar died of suffocation. The brown color you see on his gums

, is actually a bleeding phenomenon caused by suffocation, which is called "rose tooth" in forensic medicine. Moreover, if you look carefully at the old beggar's face, you will find that although it does not appear purple because it has just thawed, the entire face is swollen.

, this is also a sign of suffocation. In addition, if you see his blood, you will find that his blood must be dark red or even black purple. This is also one of the phenomena of death from suffocation..."

Just as he was talking, Song Dongxi was shocked to see Zhang Bao Li suddenly stood up and ran to the table where the water was boiling, picked up his coat and walked back. Then, he saw Zhang Bao Bao take out a bottle filled with dark red liquid from his coat pocket.

syringe and a small transparent bag.

Song Dongxi said in surprise: "What is this?"

Zhang Liang replied: "The old beggar's blood! Look, is it what you said?"

Song Dongxi's eyes widened and he said in disbelief: "Holy shit, you really got a tube of blood? You are... so professional!" Perhaps because he couldn't think of how to describe Zhang Lianyuan, Song Dongxi could only say this in the end.

He picked up the syringe, looked at it carefully, and nodded: "It should be about the same. Although I have never actually seen what the blood of a person who died of suffocation looks like, this blood is obviously darker than the blood of normal people, already showing a purple-red color.

It's probably caused by suffocation. I'll test it later to see what the blood oxygen concentration is inside." After saying that, he put the syringe aside, and then asked in a daze: "What were you talking about just now?"

Zhang Liang reminded silently: "Cause of death!"

Song Dongxi clapped his hands as if suddenly enlightened and said: "Yes, yes, the cause of death. What we can confirm now is that the old beggar did die of suffocation, but it should not be the ventilator problem you found before."

Zhang Liangliang asked in confusion: "What? From what you say, there are many other situations of suffocation?"

Song Dongxi nodded and said: "Of course, if you think about it, strangling someone to death is also suffocation, drowning in water is also suffocation, and even some nerve poisoning may also cause suffocation, but the death process in each case is different, so on the corpse

The final traces left behind are also different.”

Zhang Liang asked: "Then can you determine what kind of situation the old beggar belongs to?"

Song Dongxi shook his head this time and said: "This is a more professional clinical medicine. I'm still a little behind. Among the photos you took, the one with blood foam deep in the throat should be the most intuitive to show him.

Post-mortem symptoms, but I really don’t understand what it means. However, you don’t have to be disappointed. I just sent those relevant photos to the director of my clinical colleague and asked him to help us find out.

What is the situation?"

Song Dongxi had already helped him to this extent, so Zhang Baolian naturally had no objections. He said, "What's next, let's just wait for the result?"

Song Dongxi said: "Let's wait and see. However, I can do a test on the tube of blood you collected first. Although we can basically determine the cause of death, testing the blood oxygen content can be considered a relatively accurate value."

Zhang Baoan nodded, and Song Dongxi asked again: "By the way, what is this?" He pointed to the transparent pouch.

Zhang Liang briefly described the process of discovering the hair again. After hearing this, Song Dongxi's eyes lit up and he said excitedly: "Doesn't that mean that if we can find out the owner of these hairs, we can identify the suspect!

"

Zhang Liang did not agree immediately, but shook his head and thought deeply: "It's hard to say now. Don't forget, I did the same thing last time, and the result turned out to be like this." With that, Zhang Liang showed his face.

An expression that is unpredictable.

Song Dongxi didn't know how to answer the question, so he had to say: "Actually, you don't have to rush to a conclusion now. Maybe your previous thoughts were not wrong, but... you just need some other evidence."

Zhang Liang nodded calmly and said: "You are right, so now I understand that before the matter is clarified, anything is possible." He was silent for a moment, and then continued: "And, this matter

I have some ideas now. The whole thing seems messy, but in fact, someone has been doing something in a planned way. However, I still agree with one thing. If you can really detect the owner of the hair, maybe you can really detect it.

My speculations were of great help."

Song Dongxi didn't expect Zhang Liang would say these words in such a serious manner. He couldn't recover for a moment, but he quickly reacted and said: "I can detect the DNA in these hairs, but to be sure,

There needs to be a comparison of whose it is."

Zhang Liang thought for a while, then suddenly his eyes moved, he picked up his coat, stood up and walked out.

Song Dongxi was confused by his behavior and couldn't help shouting: "Hey, why are you going?"
