Misfortune always catches people off guard, and always causes those already beautiful lives to wither away in an instant. It is painful, but if such a scourge is man-made, then I will find out the murderer and punish him with the severest punishment.

It was the spring and summer of 2013, and on an already quiet morning, I was interrupted by a hurried phone call from Lao Lu, and because I was concentrating on the use of sulfuric acid reagents, I was so disturbed by the ringing of the phone that I dropped a few drops of sulfuric acid onto my shirt.

It's a pity that I have this brand new top.

"Come to the Dong family slaughterhouse, there is a murder here."

Lao Lu always said concisely on the phone, because I could ask in detail about the specific situation after I went to the scene.

By the time I arrived at Dongjia Town, it was already 10:33 a.m.

The taxi driver didn't know the specific location of the Dong family slaughterhouse very well, so he simply pulled over and asked a white-haired uncle on the side of the road: "Old man, how to get to the Dong family slaughterhouse?" ”

The old man said, "Do you see the fork in the road ahead?" Turn in and walk straight and you can see a large factory building. But it's better not to go today, the dead man, the police blocked the road. ”

The taxi driver ignored the old man's words and drove straight to the slaughterhouse.

The taxi listened five or six meters from the blockade.

When I got out of the car, I found the area relatively desolate, about three kilometers from the town road to the slaughterhouse. It's not a long stretch, but it's a distinction between crowded and sparsely populated areas.

So my first thought was that the slaughterhouse should be near a dumping site.

The criminal police near the cordon knew me, so I easily came to the scene of the crime.

Old Lu was bending over to examine the corpse. I was still far away, but I could see the corpse's feet, which were a little rotten, but I could tell from the shape and size of the feet that it was a young woman.

The medical examiner is conducting an autopsy, but it has been raining heavily in recent days, and in this weather, if the deceased has been dead for too long, then the clues on the deceased must be more seriously damaged.

Since the medical examiner was performing an autopsy, I didn't bother first, so I looked around.

The location of the corpse was under a red brick wall, which was the outer wall of the slaughterhouse, and under the red brick wall was overgrown knee-high and dense weeds, and if the corpse had been abandoned in this position, it would have been difficult to find in a short time.

The site was very muddy, which was also due to the heavy rain. Although the clouds in the sky today are not very thick and the sun is looming, it is difficult for this muddy ground to dry up in a short period of time due to such sunlight.

About eight meters away from the body, I noticed a patch of weeds that had been artificially crushed, which made me suspicious.

The range of rolling is large and smooth, not like stepping on it with your feet. Of course, it doesn't make sense to say who used what equipment to crush this weed.

So I concluded that this should have been formed by the person lying down and crushing.

I checked the degree of weeds crushing, and the stems and leaves of some weeds were damaged, so I can be sure that the degree of crushing is relatively large.

Anyway, my jacket also had a hole, so I simply found a clearing of weeds, and lay down to crush the weeds. In order to achieve a greater degree of crushing, I also squeezed my back hard against the weeds a few times.

But the extent of this crushing is still far from the crushing ground I found.

Then I can judge that in that place, there must have been someone who struggled desperately, and I even judged that it was not the weight of one person who crushed that weedy field, but the weight of two people.

On closer inspection, there were traces of weeds being trampled on the straight line from the crushed ground to the corpse. Because there is a regular interval lodging in the weeds, it is exactly one step away from the person.

Then I made assumptions. The killer killed the deceased in the weedy crushing area, and then moved the deceased to a more secluded corner.

Now I can basically determine that this is the first scene, and the location of the body is only less than eight meters away from the first scene.

However, because of the recent heavy rain, the footprints left by the murderer on the ground are blurred, and it is difficult to use them as a basis for judgment.

The forensic doctor finished the autopsy, and Lao Lu and I listened to the forensic doctor's report together.

"The deceased was a female, aged between 16 and 18 years, 158 tall, weighed about 87 pounds, and died more than 48 hours. There were obvious strangulation marks on the neck, and blood oozing from the mouth and nose, and the preliminary judgment was that someone was choking the neck and covering the mouth and nose, resulting in suffocation and death. The woman's lower body was scattered next to the corpse in a denim skirt and underwear, and her lower body was bleeding with lacerations, and she had been sexually assaulted before her death. I estimate that the deceased should have sperm spots in the lower body of the murderer, and I will conduct further investigation after the body is brought back to the forensic center. ”

Lao Lu nodded and said, "Well, if there are sperm spots, extract the DNA data as soon as possible." ”

The medical examiner said yes.

I examined the woman's corpse again, and she was too decomposed to discern physical features from her face. But the characteristics of the deceased can be found in clothing and ornaments.

A white bow hairpin was found in the corpse's scattered hair, and her blouse was torn to the point that it was cut, and it seems that the murderer was extremely cruel when committing the crime. This top of hers is a white top with a Mickey Mouse pattern.

Then this poor girl has two notable physical features, one is the white bow hairpin, but the white Mickey Mouse pattern top.

At this time, a criminal policeman shouted in the distance: "Captain, there is a discovery." ”

Lao Lu and I walked up to the criminal policeman and found two white paper bags lying in the weeds, which are paper bags used by clothing stores to store clothes, but the brand is just a miscellaneous brand, which makes it difficult to determine what kind of store this paper bag comes from.

In the paper bags, we found a number of items. A men's sportswear, toothpaste, toothbrush, facial cleanser, shampoo and makeup, girls' clothes, sanitary napkins, and a ticket from Fengjie to Wanzhou.

In this pocket, there are two things that catch my eye.

One is this male sportswear, why does a girl have a men's sportswear in her bag? So will the girl's death have anything to do with the owner of this tracksuit?

The second is this ticket from Fengjie to Wanzhou, the ticket was four days ago, and the departure time is 8 o'clock in the morning. This information is crucial, so it can be determined that the deceased should have been killed after coming to Wanzhou four days ago. Because the two pockets left at the scene can be determined that the deceased was killed after getting out of the car and before returning to his foothold in Wanzhou.

Now there is another problem, which is that this crime scene is very strange.

This is not a road, and there are no country roads for pedestrians, so why did the deceased appear here? Could it be that he was brought here after being stunned?

However, there were no rut marks at the scene, so it was impossible for someone to bring them here.

Then I checked the two shoes that were about a meter away from the deceased.

I sniffed the dirt on the soles of the shoes and tasted the dirt, and walked two hundred meters away from the scene of the crime and checked the dirt as well. It was found that the dirt on the soles of the shoes was exactly the same as the dirt on the site.

Then I can be sure that the deceased came here on his own.

But this is very strange, there is no village in front of this place, there is no store in the back, how could she come here on her own? This is a big doubt.

Of course, there is another doubt, and that is the identity of the deceased.

There was nothing at the scene to prove the identity of the deceased, she had no wallet, no ID card, no mobile phone on her. But I am sure that these things must have been carried by the deceased during his lifetime. How can a young woman who goes out of the house not bring her ID card, wallet and mobile phone?

Then I can now make a characterization of this case, which is a vicious robbery, rape and murder case.

Lao Lu also agreed with my characterization.

Lao Lu said: "It seems that I have to check the station through this ticket, maybe from the surveillance video of the station, you can find the video information of this girl." ”

I said, "Well, that's the most straightforward way. But it is not enough to find the video material, because we have no way to determine the identity of the deceased. So the top priority now is to determine the identity of the deceased, and from her identity, see if the suspect can be found. Because the girl came to this remote place on her own, is it possible that an acquaintance committed the crime, and the girl was sexually assaulted and killed after being asked to this place. ”

Lao Lu said: "It seems that it is another big investigation." ”

I frowned and pondered for a while, because I knew that although a large investigation was possible, it was also the most time-consuming and labor-intensive.

Since I am a consultant invited by Lao Lu, I should solve problems for Lao Lu at this time and reduce the workload of Lao Lu.

So I said, "The girl is very young, what do you think her identity will be at such an age?" ”

Lao Lu said without thinking: "Of course, it is more likely to be a student. ”

I nodded and said, "Indeed, and in the vicinity, there is an information school, and maybe this girl is a student of this school." ”

Lao Lu's eyes lit up and said, "Indeed, if it is a student of this school, then this girl should be easy to find." ”

Since then, the investigation has continued to be carried out intensively.

But unexpectedly, there was a bottleneck in the investigation. Because the girl was not a student of the information school, and no sperm spots were found in the girl's lower body.

But one thing is fortunate that in the surveillance of the bus station, we found the video footage of the girl.
