When the museum's archaeologists were studying the cave, I put on my gloves and walked around the cave and found a discarded Coke bottle and a few cigarette butts.

As you can see from the style of the cigarette butts and the bite marks on the filter, these cigarette butts should have been left by different people. I handed over the cigarette butts and Coke bottles I found to the detective police and asked them to do a DNA analysis of the residues on the Coke bottles and cigarette butts.

I know that these things are more heavily contaminated, but I believe that with the current science and technology, it is possible to extract DNA from these residues. Moreover, the comrades of the investigation team also told me that they had also extracted DNA from more seriously contaminated evidence.

I also told them that they could investigate the origin of the Coke bottle and use the barcode on the bottle to find out where the bottle was sold. Finding a point of sale will certainly gather some information about the criminals as well.

Tang Zhenguo also walked around among the weeds, helping to find some suspicious clues. He also tried his best in every case I handled, although he didn't have much experience in solving the case, and he couldn't make reasonable inferences based on the environment and physical evidence at the scene, but he had a keen eye, and he could always find something I missed.

"Ouyang, look, these seem to be blood stains." Tang Zhenguo squatted on the ground and looked at the grass.

I strode across the ditch in front of me, climbed up a small low mound, walked to Tang Zhenguo's side, and followed Tang Zhenguo's line of sight, and saw a lump of napkins in the grass, some parts of which were already dark brown. Apparently, the tissue had been used to wipe the blood.

I unfolded the bloody napkin, and the quality of the paper was very good, and it was a relatively high-end sachet of napkins. Because of the high quality, this napkin did not appear to be damaged.

Judging from the amount of blood stains wiped on the paper, the injured person is not serious and should belong to the skin trauma, but it may also be left by the blood stains left on the murder weapon. However, no other blood stains were found at the scene, and it can be determined that it is more likely that this piece of paper was wiped against the injured person.

From this napkin, I noticed that there is a lotus-like mark on the four corners of the napkin, which seems to be the brand logo of the tissue.

I also handed over the bloody tissue to the investigating criminal police, and I also explained two things. First, the test of blood DNA on napkins; Second, the verification of the paper towel brand logo, check what factory produces this paper towel, and where is this paper towel factory?

When I explained this, I walked to the cave. I saw an old professor with reading glasses, white hair at the roots, and black hair at the tip, holding a wooden stick in his hand, shaking his head with a look of regret.

I could see that the wooden strip in his hand was obviously not this surrounding item, and I thought to myself: Could this be some clue left by the tomb robbers?

So I stepped forward and asked the old professor, "Old comrade, this piece of wood in your hand doesn't seem to be a product of the surrounding area, but a piece of wood dug out of the hole by criminals?" ”

The old professor helped his old glasses, sighed and said, "This is evidence of the grave robber's evil, hey, it's a pity, it's a pity." ”

I didn't quite understand, so I asked, "Is this broken wooden strip from the coffin?" ”

The old professor stared at the wooden strip in his hand and said, "This is a fragment of the yellow intestine inscription in the tomb. ”

At this time, Tang Zhenguo, Lao Lu and several criminal policemen also came around, but we all heard it in a fog, so I asked again: "What is this yellow intestine question you are talking about?" ”

The old professor glanced at us and said: "The yellow intestine inscription is mainly a tomb coffin chamber used by the emperor of the Zhou Dynasty and the Han Dynasty. The so-called "yellow intestine", that is, the yellow heart of the cypress, is the yellow cypress after peeling. Because the wood used for construction is a cypress with the bark stripped of the bark, the overall wood color is named because of the light yellow. The so-called "problematic" is a way of stacking wood. The basic characteristics of the structure are: first, layer by layer tiling, stacking, generally do not need to chisel out concave and convex for connection; The second is "the wood is introverted", that is, the wooden strips built by the four walls of the inscription are all perpendicular to the siding of the coffin chamber on the same side, if you look at it from the inside, the four walls are only seen at the end of the wooden strips, and the name of the inscription is derived from this specific way. ”

We all sighed, but I know there are still a lot of people who don't understand.

In my explanation of the old professor, I heard an interesting place, he said that this yellow intestine inscription is only worthy of the emperor-level tomb, is it that we are under the tomb of the emperor of a certain period?

After I asked the old professor about this question, the old professor shook his head and said: "According to the geographical location of our Wanzhou in history, it is unlikely that it is the tomb of the emperor, but the owner of the tomb must be a high-ranking official or a person who has made great military achievements. Therefore, after his death, with the permission of the Son of Heaven, he used a high-standard coffin chamber like the yellow intestine inscription. ”

I asked, "Since the specifications of the coffin have reached the imperial level, the cultural relics inside will definitely be priceless." ”

The old professor nodded and said, "Yes." ”

So I hurriedly said to Lao Lu: "Pay attention to the antique market, and check the cultural relics of the Zhou Dynasty and the Han Dynasty that have recently appeared with a lot of value, maybe it is the stolen goods of this tomb robbery." ”

Lao Lu nodded.

It was still hot, but in the autopsy room at the forensic center, it was still cool. I think this coolness is mainly due to the role of air conditioning. However, Tang Zhenguo doesn't think so, he thinks that the coolness here has an extra kind of coldness, which is creepy. So he rarely enters the autopsy room, and usually sits in the corridor outside to play with his mobile phone, and even the wifi here is already automatically connected to his mobile phone.

Liu Lili was helping me put on a protective suit, and he moved his mouth while moving his hands: "How about I help you wear a suit like this in the future?" ”

I rolled my eyes and said, "I barely wear a suit. ”

She hurriedly said, "Don't you wear it when you get married?" ”

I originally wanted to say that I could wear Tang clothes when I got married, but after thinking about it, I still didn't take the words of this post-90s weird girl, so I chose to keep silent.

"Okay, get dressed. Wear another hat. Liu Lili said as she put a protective hat on my head, and I felt her fingertips touch my scalp.

Maybe ordinary people would resist her hands, a pair of hands that touch corpses every day, but I won't. As for why, I can't say, maybe it's because of my profession.

When everything was done, we removed the three incinerated bodies from the chilly corpse cabinet.

Opening the body bag, I put the three cremated bodies on the coroner's table one by one, and from the outside, these three bodies have been dissected, and it is obvious that Liu Lili has done a detailed examination of the three corpses. That's why I'm here today, to understand the real cause of these three deaths.

Maybe the average person will just ask and know a result. But that's not my style of doing things, I'm going to personally conduct in-depth investigations and studies of the victim's body. It can be said that this is my serious and responsible attitude towards my work, and it can also be said that it is a habit of mine.

To be clear in advance, I'm not a pervert, and I don't have a necrophilia, and I do this just to confirm the saying: do one line, love one line.

I pointed to the corpse with half of the head missing and said, "This male corpse died from a shot in the head, so there shouldn't be much difference, right?" ”

Liu Lili said: "Yes, but I found in the autopsy that this person should be no more than 30 years old, but his lungs have been seriously damaged, and it is estimated that he has smoked for more than 20 years." ”

I frowned and said, "I didn't learn well from a young age. ”

Then I broke open the man's mouth, looked at the teeth, and said, "Did you take the pulp and send it for DNA testing?" ”

Liu Lili said yes.

I nodded, and turned to the male corpse with one missing front tooth. This male corpse is the male corpse with silver teeth, and his silver teeth have been taken away by the Technical Identification Department, trying to find a breakthrough in the identity of the deceased on that silver tooth, but to no avail. I guess this kind of silver tooth is the work of some old craftsmen, so it is difficult to find records.

I asked, "How did this man die?" ”

Liu Lili said: "This person was shot in the back, the bullet pierced the heart and died, and the bullet finally pierced the chest, leaving no bullet in his body. ”

After speaking, Liu Lili pointed out the wound to me, although it was burned, but after the body was cleaned, a closer look can still see the wounds on the chest and back.

I leaned over to take a closer look and said, "This wound should be caused by a small-caliber pistol, it seems that this group of tomb robbers is well-armed, not only *, but also pistols, not to be underestimated." ”

I straightened up, walked over to the third burned man's body, and said, "Let me guess, this man was also shot and killed?" ”

Liu Lili said: "Guess again." ”

I said, "Stabbed to death with a sharp weapon?" ”

Liu Lili shook her head and said, "It's not right either. ”

I squinted, looked at the ceiling light, and said, "Hit in the head with a blunt object?" ”

Liu Lili smiled and said, "It's close." ”

I said impatiently, "Don't sell it, just say it." ”

Liu Lili looked at me with an anxious look, and actually laughed, and said: "There are still things that Detective Ouyang can't guess, hehehe......"

I said solemnly: "I'm not an encyclopedia, and besides, don't smile in front of the dead." ”

Liu Lili pouted and said, "If you don't laugh, you won't laugh." Let me tell you, this man was hit in the head by a random punch to death, and his ribs were also broken, so he should have been caused by heavy punches. It took my colleagues and I a long time to determine the cause of death of this body. How's that, I'm a cow! ”

Punched to death! I really didn't expect it.
