Cao Zhen and Jing SA, as criminal policemen, often deal with forensic doctors. They are also familiar with the forensic methods, and nod their heads to Hu Hu's judgment.

Jing SA squatted down and added: "the eyes are protruding, the face is narrow and long, but the lower part is slightly short. It should be Asian."

"Yes, according to the seam of the skull, it has not fully healed, which proves that the deceased is very young and should be 17-25 years old, but this is only a preliminary judgment. If we can see the molar, we should be able to make a more correct judgment."

Every tooth of human has its development law, and this process has a relatively stable time range, which can be used as the basis for judging the age. In addition, teeth will wear in the process of life, and this kind of wear can also be used to infer the age of the tooth owner.

However, judging gender and age by naked eye observation is really simple and fast for experienced people, but due to the subjectivity, it is inevitable to misjudge, so we have to wait for professional forensic expertise.

Because forensic medicine can make characteristic judgment from many different places, such as sternum, sacrum, pelvis, etc.

If the skull can be taken out, it can be further inferred from the crevices of teeth, posterior transverse and palatal.

Although it has not been officially confirmed by the forensic medicine, he has his own identification.

"If I guess correctly, this man should be Yang Xiao."

Cao Zhen looked at her in surprise, "you say this is Yang Xiao? But isn't he missing? " The same is true of the information Li Shangong found.

"Missing and dead are just literal meanings. In fact, we only know how to find them. Obviously, what we find is not a living person, but a person who has been dead for a long time."

According to the age of the remains, if he was really Yang Xiao, he would have been dead for nearly 40 years.

"How could Yang Xiao die in Du's family? He had a problem with Du Fu. Du Fu kicked him." Yang Xiao couldn't have been in Du's family just because of this resentment.

"Is it that he was angry, climbed over the wall and stole into Du's house for revenge, and then was found and killed by mistake?"

He shook his head. "It's impossible!"

"Why?"

"Because of this tree!"

Jing SA scratched his hair and said, "Ho Ho, could you make it clear? What does it have to do with trees? "

"Well, suppose Yang Xiao and Du Fu are lovers of each other?"

"Ha?"

This assumption is too unexpected.

"Don't be so surprised. Listen to me."

"Oh Jing SA obediently raised his ears, no longer cut in.

"Ah Jing, do you remember Huang Zhaodi said that Dufu asked her when to borrow money?"

"I remember, two months before Duff's parents died, that is, after the Spring Festival..."

He nodded and looked at Cao Zhen, "when did Yang Xiao disappear?"

"It's after the Spring Festival..." Cao Zhen suddenly felt a chill in his mind.

Yang Xiao disappeared at the same time as Dufu borrowed money, and Yang Xiao stole all the money from the students in the same dormitory before he disappeared.

"Wait, that's not right. You said that Dufu had an affair with the painting teacher. How did she become Yang Xiao again?"

"According to Huang Zhaodi's words, I did think so at first, but the fact is not so. Dufu and Yang Xiao should be a couple, but they just kept it from everyone. I think Dufu's kicking and hurting him should have another secret. If they don't have such a relationship, Yang Xiao's remains can't appear under the tree engraved with Dufu's name. In a sense, this tree represents Duff, or her dowry, which is of great significance. If it's not the person in my heart, how can he be buried here? "

This is enough to prove that Yang Xiao and Du Fu have a good friendship and are not enemies.

"What about the painting teacher?"

"As a cover up, I guess every time Dufu went to learn painting, he actually went to see Yang Xiao secretly, but in school, they never had any contact."

Huang Zhaodi doesn't know what Dufu did after she went to the painting classroom, so it's not surprising that she didn't know, which also led to the misunderstanding at the beginning.

It can only be said that these two people are hiding too deep.

"Duanmu, if it's really like what you said, isn't it contradictory for Dufu to kick Yang Xiao?"

"No, it's not contradictory. I suppose two people fall in love. Then what kind of things do you think will make Duff kick his beloved heartlessly? There's only one possibility. Duff is protecting him in order to keep him away from himself."

"You mean Yang Xiao may know about the Du family selling organs?"

"Nine times out of ten!"

Cao Zhen is silent, because after that, Yang Xiao did change school and left huangjiatang. His various obstinacy and truancy in school also have an explanation. He is trying to go back to Dufu by all means.

Finally, the two may meet successfully, and then meet to elope together.

In this way, borrowing and stealing money also have a good explanation.

But is that true?

Maybe it's too mysterious.

It must be incredible for them to know that all of a sudden, but this is the most logical possibility she thinks.

"Again, it's just my personal judgment. The final conclusion can only be determined after forensic identification of the remains and clues from the painting classroom."

Jing SA is not as calm as she is. She asks, "if this is Yang Xiao, as you said, he and Du Fu are a couple, who is the one who killed him? It can't be Duff himself

"It can't be Duff, of course."

"Who else is there?"

After asking, Jing SA was silent.

Yang Xiao died in Du's family. If it wasn't Du Fu who killed him, who else?

Who else?

Only Duff's father or mother.
