Ning Shuyi stared at the information he could collect, and question marks kept coming out of his head.

After a while, Huo Yan also returned, and he told Ning Shuyi that most of the corpses had been excavated from the cement blocks, and judging from the degree of decomposition of the corpses, the two men may have died a little longer than the neighbors noticed their disappearance.

It is precisely because of this, coupled with the fact that the cement used to seal the body is high-hardness cement, and in the process of separating the body from the cement block, the skin on the face and body surface of the deceased will inevitably be damaged to a certain extent.

The facial damage of the two deceased was particularly severe, and the relatively small peripheral positions of the fingers and toes could not be pulled out of the cement intact, which doomed the fingerprints of the deceased to be difficult to collect.

However, fortunately, after examining the situation, the forensic doctor determined that the current degree of damage had little impact on determining the real cause of death of the deceased, which can be regarded as a relatively optimistic news in the large number of bad things that this case has brought from the beginning.

In addition, bone age testing for the two deceased is already underway.

A few hours later, around midnight, the bone age and blood type of the two deceased have also been released, from the perspective of bone age, the detected age range does include the actual age of Deng Qingrong and Chang Junchao, and the blood type is also consistent with the foundation left on the relevant records on the intranet.

But after such a comparison, Ning Shuyi found another problem that she hadn't noticed before.

"This Chang Junchao, his blood type ...... Doesn't seem right! She pointed to the blood type on the test report and asked Huo Yan to see, "You see, my mother Deng Qingrong is blood type A and B, and my father Chang Rong, who has passed away, is blood type B, but Chang Junchao, he is blood type O." ”

"Parents with blood type AB and blood type B can't have children with blood type O?" Huo Yan didn't know much about this, but listening to Ning Shuyi's tone, he was able to deduce such a conclusion from it.

Ning Shuyi slowly shook his head: "It's true that you can't give birth to a child with type O blood!"

Then this is interesting, if we just test the blood type of the deceased and find this blood type mismatch, then we can also guess whether the identity of the deceased is not Deng Qingrong and Chang Junchao's mother and son.

The current situation is that even the personal information on the intranet, the blood group records of the three members of the Chang family are also exactly the same and clearly registered, which must not be wrong.

Then the relationship between this family of three is a bit interesting.

Didn't Deng Qingrong tell her old neighbors that she had given birth to two children before and was unable to survive, but then she finally recuperated and gave birth to Chang Junchao, this time it was finally smoothly pulled up?

As a result, it seems now that Chang Junchao either has no blood relationship with Deng Qingrong and Chang Rong at all, or Deng Qingrong is indeed Chang Junchao's biological mother, but his biological father is someone else.

There is such a relationship, we must consider it, after all, this kind of thing is likely to involve some shady secrets.

Generally speaking, unless it is an adopted child, that kind of secrecy is dangerous. ”

Huo Yan nodded, thoughtful.

After a moment of silence, he said to Ning Shuyi: "The investigation at the scene of the crime found that there were indeed traces of theft, but the specific amount of property lost is unknown at present, and it remains to be further confirmed.

What is certain is that the mobile phones used by the mother and son before their deaths should have been taken away, and there are no cash, precious metals, jewelry and other things in the home, except for large household appliances such as TVs and refrigerators.

The door lock can find traces of technical unlocking, and the person who enters the room still has certain means.

In addition, there are a large number of traces that have been roughly wiped at the scene, but they still collected a fingerprint that is not complete, the only problem is that the clarity of this fingerprint is very unsatisfactory, so there is no way to get a comparison result for the time being. ”

"The exact cause of death hasn't come out yet, has it?" Ning Shuyi asked.

Huo Yan nodded: "Forensic Doctor Zhang, they are preparing to conduct an autopsy on the two corpses to confirm the cause of death, and it is estimated that there will be results in the second half of the night or tomorrow morning." ”

Ning Shuyi sighed, poured a glass of water for Huo Yan, and motioned for him to rest a little.

At the beginning of this case, it gave people a not very optimistic premonition, and it is estimated that they have been busy in the past few days.

On the negative side, Deng Qingrong and Chang Junchao's mother and son are both foreigners, and they don't seem to have any close relatives locally.

The information provided by the neighbors today is already able to tell a certain problem, and they seem to have almost no friends who move around a lot.

Sometimes, in the investigation stage, we are not afraid that the victim's social relationship is too complicated, and no matter how complicated it is, at least we can distinguish the priority and pay attention to the exclusion, and there will always be a direction to surface.

But this kind of social relationship is too simple, but it is even more of a headache, and there is no way to start.

However, after all, people are social, social animals, it is impossible to live in complete isolation from the world, as long as they are still active in society, they will need to come into contact with others, and they will leave some action tracks.

Now there is too little at hand to know where to start, which can only mean that you have not dug deep enough, as long as you continue to dig deeper, there will always be gains.

Ning Shuyi comforted himself like this, and thought about it again, there is still a positive side to this matter, he is bound to work overtime frequently in the past few days, his brother-in-law Nie Guang went to the field, his parents are at his sister's house, and the "last madness" of the few people upstairs naturally does not affect anyone.

For the first time, she thought that she might have to live in the duty room in the next few days, and she even felt a little bit of anticipation.

Sleeping until she wakes up naturally or something, she no longer has the luxury of expecting, at least she can let herself be undisturbed from the pillow next to the pillow until she opens her eyes the next morning, this is her highest pursuit at this stage.

In this way, they tossed around in the unit for most of the night, and in the second half of the night, they each found a duty room to make do with it and took a break for more than three hours, and they received a notice when they got up early in the morning that the autopsy report came out.

After the autopsy, it was confirmed that the female deceased suspected of Deng Qingrong died of suffocation, and the male deceased who was sealed in cement with her, suspected to be Deng Qingrong's son Chang Junchao, was more complicated, first being hit in the back of the head with a blunt object, and then strangling the neck bone.

What surprised them even more was that although Deng Qingrong said that she died of mechanical asphyxiation, it was not entirely due to mechanical asphyxia, and it can be seen from the characteristics of her lungs that she had indeed suffered mechanical asphyxia before she was killed, but deep in her nasal cavity, the forensic doctor found that there was also a large amount of cement slurry.

Happy holidays to friends and children!

As long as there are dreams in our hearts, we will always be babies~!
