Chapter 352: Drowning and Dumping (Part 2)

"Ancient method?" Li Le was stunned and looked at Han Xu in surprise, "You are not saying that you understand all these things?"

"I can't say I understand them, I just know a little bit." Han Xu was humble at this time.

What Chengzi admired most was Han Xu's knowledge of all things, so he couldn't help but ask, "What ancient method is it?"

Li Le got excited when he heard this, and came over and said, "I've heard of the steaming bone autopsy method before, Han Xu, is this what you are talking about?"

Han Xu shook his head and replied with certainty, "The steaming bone autopsy method you mentioned is mainly used to check whether the skeleton has suffered any serious injuries before death.

That method is very old. Have you heard of using this method now?"

Without waiting for Li Le to say anything else, Han Xu continued, "Although some ancient autopsy methods are outdated, they still make sense, such as the steaming bone autopsy you just mentioned!"

Chengzi may not have watched related film and television dramas, and looked at Han Xu blankly, "Steaming bones? Are you talking about steaming human bones?"

"What do you think?" Li Le said unhappily.

Han Xu shook his head and explained, "This method is actually quite useful. The specific operation method is to first choose a time period with good weather, then wash the bones several times with clean water, and then put them in the steamer to steam."

"Really steaming?" Orange was a little stunned.

"Of course not, this is the method recorded in "Xiyuanlu." Li Le is much better than Orange, at least he knows the origin of this bone steaming method.

Han Xu nodded, "Yes, it's the method in "Washing Away Wrongs". Next, we need to dig a big pit on the ground, 1.6 meters long, 1 meter wide, and about 60 centimeters deep. Then, we need to burn it with firewood and charcoal, and burn the whole pit red. Then, we need to pour two kilograms of good wine and about five kilograms of aged vinegar into the pit. When smoke is aroused, we need to cover the pit mouth and wait patiently for about two hours.

At this time, we can take out the bones and look at them. If there are scars, gaps, or obvious abnormalities on the bones, it proves that the deceased was injured before his death."

"Fuck, Han Xu, how do you know so many things? To be honest, are you cheating?" Orange was confused. Although he didn't understand the theory, he was enlightened.

Han Xu smiled indifferently and ignored it.

Li Le was getting excited. "Then how can we tell whether the deceased drowned or was dumped after death in this situation?"

"The ancient method I mentioned before is like the blood test for kinship, which still needs to be verified, but the current technology and technology are enough to solve this problem." Han Xu replied truthfully.

"How to solve it?" Li Le asked doubtfully.

Han Xu continued, "If the two previous identification methods still cannot determine whether the deceased drowned, then the last step must be used, which is to conduct diatom testing in the laboratory.

Diatoms, as you know, are a type of plankton widely found in water.

Of course, the dead water environment at the bottom of the well is more likely to breed diatoms.

Assuming that the deceased entered the water before his death, he must have some actions such as breathing and swallowing. In the process of inhaling water through the mouth and nose, plankton such as diatoms will follow the water flow into the human respiratory tract, lungs, and blood, and then flow throughout the body with the blood.

If the deceased drowned before his death, in various organs, especially the lungs , even a certain amount of diatoms can be detected in bones and teeth.

The next thing is easy to say. By comparing the diatoms detected in these places with the diatoms in the waters of the crime scene, it can basically be determined whether the person drowned in this area. "

Orange and Li Le understood the general idea and shook their heads, "Han Xu, you are not a technical detective, how come you seem to know more than Song Jiaer and Xiao Xiao?"

"I am just making a small fuss, it doesn't matter. If Song Jiaer and Xiao Xiao come, they can probably use a hundred methods to identify whether the deceased drowned."

Han Xu's words are a bit exaggerated, but it also indirectly illustrates the importance of modern technical detective to the case!

How does that sentence go? Usually, what can improve the rate of solving a case is not those mysterious psychology things, but a real technology!

To really solve a case, it depends on the perfect combination of criminal investigation and technical investigation!

For example, Dr. Li, who is known as a detective, relies more on solid technical support!

In fact, back to the case itself, in this case of dumping corpses in the well, whether the victim drowned is not so important.

What is more important is to find the source of the corpse, that is, the identity information of the victim.

The previous Lighthouse No. 3 case was temporarily shelved because the source of the corpse could not be found.

Han Xu thought that he needed to find out the identity information of the victim, and his eyes fell on the female skeleton again.

"It is estimated to be about 1.6 meters tall, Han Xu, do you think this remains could be Xiao Keba's?" Li Le seemed to be a roundworm in Han Xu's stomach, and he caught the key point at once.

Han Xu nodded, "This possibility cannot be ruled out!"

"But it's a pity that we don't know Xiao Keba's real name. Even if we can extract DNA samples from the bones, there is no way to match them."

Li Le grinned, and every word hit the point.

Qin Fen and Miao Xiaofeng over there were arguing about this issue before.

The two criminal investigation team leaders argued back and forth, but in the end there was still no result.

"Captain Qin, this is not your northern suburbs. You are stretching your hand too far!" Miao Xiaofeng saw that the argument was fruitless, so she started to argue directly.

Qin Fen was speechless, "Hey, Miao Xiaofeng, what you said is not right. If it weren't for my people, could you have discovered this case?"

Miao Xiaofeng curled her lips, as if there was nothing wrong with what she said, but she was not willing to suffer a loss, "Is it your people? Can your small temple accommodate Han Xu, a great god?"

Qin Fen seemed to be poked at a sore spot, but when he saw the environment at the scene, he knew that it was not a place for bickering, so he simply didn't argue with Miao Xiaofeng and didn't argue back.

Han Xu saw that the argument and bickering had stopped, and walked over a few steps, "Captain Qin, Captain Miao, I have a way, I don't know if it will work!"

"What do you have?" Qin Fen asked in astonishment. In fact, he knew that since Han Xu said it, he must be 80% sure.

Miao Xiaofeng stepped forward when she heard Han Xu had a solution, "Don't keep us in suspense, tell us now!"

The case that left the two criminal investigation captains helpless was extremely difficult.

At least the conventional methods of handling cases were no longer so effective.

Han Xu looked back at the two corpses, one large and one small, pursed his lips, and said calmly,

"I'll try to draw it!"
