Lu Shaojia's little ancestor is a forensic doctor

Chapter 502 Strange Substance
Wang Dakui tapped the remote control twice, and several photos of the scene appeared on the big screen, all of which were recent photos of the deceased taken by the police officers who salvaged the body at that time.

"Everyone knows the outer river in Pinggang District. The two sides of the entire river are almost industrial areas, and the lower reaches of the river are connected to the sea. Usually the river looks calm, but the water underneath is still very fast, and the further downstream The wider the river, the deeper the water level."

"When the deceased was salvaged, a bag of stones weighing fifty catties was tied around his waist, and the body was already highly decomposed. According to the forensic autopsy, the deceased had been dead for four or five days, and the entire body had already appeared as a giant. From the outside, the identity of the deceased cannot be determined at all.”

"Although forensic doctor Zhang later extracted the DNA of the deceased and compared it with the database, but so far no clues have been found. What we can do now is to send people along the entire river to investigate the missing persons one by one."

When the words fell, Wang Dakui looked at Meng Yao with a look of embarrassment on his face, "Not only the living can't bear the weather, but even the dead can't bear it. The corpses have been soaked in the water for so long. If we wait for us to go door-to-door Let alone whether it can be found after the investigation, even if it is found, it will probably add a lot of difficulty to the investigation."

"So now it is necessary to find out the identity of the deceased before we can continue to investigate."

After listening to him, Meng Yao glanced at Zhang Ming who was next to him. The other party handed her the autopsy report in his hands in embarrassment. here."

The implication: Even if there is a fault, it is definitely not on me.

Ignoring him, Meng Yao just looked at the autopsy report in his hand. Even though Zhang Ming didn't really admire her, he still pricked up his ears and waited to hear what she had to say.

After quickly scanning the autopsy report, Meng Yao frowned and said in a calm voice, "Since the DNA cannot match, why didn't the fingerprints of the deceased be extracted for comparison."

Zhang Ming was taken aback for a moment, then blushed instantly, lowered his head and did not speak.

It was indeed his negligence, because in the case of such a move, the corpses fished out like this are all done for DNA to determine their identity, so he forgot to take double insurance for a while.

"The deceased was a woman. Forensic doctor Zhang's hand is probably a bit big. Remember to change it to a smaller hand later."

Because human hands and feet have a lot of stratum corneum, thin subcutaneous fat and less muscular fascia adhesion, after long-term immersion in water, the epidermis and dermis will separate and fall off from the underlying tissue, forming a A very complete human leather glove (footmuff) with fingernails (toenails).

In fact, this situation is the same after swimming and bathing, because after soaking for a long time, you will find that the skin on your hands is wrinkled, but the corpse soaks for a longer time.

Gloves that are taken off like this can be soaked in formalin for a short time (3-5 hours) to fix them, and then choose a person with small hands to wear the cut out human leather finger cots on their fingers, just like wearing a single finger Like a finger cot, you can press to extract a complete fingerprint to identify the deceased.

Seeing that no one spoke, Meng Yao explained, "Everyone knows that the entire river in Pinggang District is an industrial area, and there are many places like that, and the people are mixed, especially those migrant workers. Some of them Those who do not have a temporary residence permit, some have not entered complete identity information for one reason or another, so most factories will choose to let workers have their fingerprints when signing contracts or paying wages.”

After saying so much in one breath, Meng Yao stopped, and she believed that everyone would understand what she meant even if she didn't say anything.

Even if they still have to check one by one, they are much more likely to find the target if they have fingerprints, which is more detailed than just searching for missing persons.

And this case was followed by Zhang Ming, and Meng Yao only needed to provide him with technical support. She didn't plan to go to the battle to extract the fingerprints by herself, besides, there was Zhao Zimo.

Meng Yao quietly swept her hand over her still-flat lower abdomen. She reminded herself all the time that she was not alone. Although she didn't think seeing the dead in this situation was unlucky, she would still be able to reduce some of the pain. Minimize as much as possible, after all, she is responsible for the child in her stomach.

In fact, the key point is that she sneaked out when she came out just now, and she still doesn't know how to explain to Lu Zhixing after chasing her later.

The meeting continued, and Wang Dakui talked about the situation of the deceased again.

"Except for the bag of stones tied to the deceased, the gold chains around her neck and wrists are still there. From this point, it can be preliminarily ruled out that the murderer was killed for money."

"And from the autopsy report, the deceased not only suffered trauma before being killed. Judging from the sand in the mouth of the deceased, the deceased should have been breathing before being thrown into the river, and the person was drowned alive."

Meng Yao could see what he said from the autopsy report, but she hesitated for a while in one of the specially marked places.

"What does the pending confirmation marked on it mean?" Meng Yao pointed to a place on it to show Zhang Ming, waiting for him to clarify for herself.

Zhang Ming turned his head and looked, "During the autopsy, some sand was found in the mouth of the deceased, but it was white and looked like mud. I guess it was inhaled by the deceased when he was struggling in the water. .”

"But this kind of sand is different from what we have seen in the past. Anyway, it is still not sure what its composition is."

At this time, Wang Dakui said, "In fact, we all think that this kind of sand may allow us to find the scene of the murder of the deceased faster, or her sinking point, but we haven't figured out what kind of soil it is until now." .”

Seeing Meng Yao frowned, Zhang Ming thought for a while and took out a small bottle with the length of a little finger out of his pocket and put it on the table, and said, "This is that kind of soil. I was planning to go to a geological expert to have a look at it this afternoon. Forensic doctor Meng can take a look at what the ingredients are."

In fact, to be honest, even though he has never been convinced by Meng Yao, sometimes he has to admit that Meng Yao has seen more strange cases than him in the past few years in the local area, and knows more than him. A little bit.

To put it in words that he didn't want to admit, Meng Yao understood more complicated things.

In the small bottle as thick as a little finger, some white fine sand had just covered the bottom of the bottle, it was really hard to tell what it was just by looking at it, Meng Yao frowned.

"I found this from the tongue and lungs of the deceased, and under the light, there will be glittering components in the sand, anyway, I have never seen it before."
