My name is Gao Fei and I am studying at a well-known police academy in Province G, specializing in criminal psychology.

After graduating, I chose to become a private investigator and am still active in the field of criminal investigation.

Over the years, I have seen countless large and small cases, strange cases, unsolved cases, and even the top ten supernatural cases that have been circulated in the market, and I have participated in them. The hidden truths are absolutely beyond your imagination, and I don't want them to be buried, so I'm going to write about them.

Three years ago, my fiancée mysteriously disappeared from the world, and since then, her fate is unknown, and for so many years, I have been using my network to find her whereabouts.

A month ago, I finally got the news from a teacher at my university that someone had seen my fiancée in Heijin City, Province G.

The teacher's surname was Yan, and he took great care of me during the school period, and I kept calling him Yan.

Lao Yan has always helped the judiciary and has a wide network in the police community. He promised to find out his wife's whereabouts for me, and in exchange for me solving a small case for him.

At that time, what he said was very simple, and I agreed happily, but later I found out that this so-called "small case" may be the most dangerous and bizarre case I have ever encountered in my life.

A month ago, a horrific rape and murder case occurred in Heijin City, G Province, which caused a sensation.

At that time, when Zhao Bo was cleaning the public bathroom in the eastern suburbs of the city, he suddenly found that the door of one of the single rooms was closed, and the rare sound of water came out.

At this time, at four o'clock in the morning, it is not yet dawn, at this time, who will be bathing inside?

After waiting for half an hour, but still didn't see anyone inside, Zhao Bo was a little impatient, picked up a flashlight, and planned to come forward and knock on the door.

He had only taken a few steps before he froze.

In front of the floor of the single room, several women's clothes were scattered in a mess, some of which had been torn and tattered. However, there was a set of red underwear mixed with it, which made Zhao Bo, an old man, blush.

At the same time, he also felt that something was wrong, how could ordinary people take a bath and throw their clothes on the ground outside?

Zhao Bo plucked up his courage, walked to the door panel, and knocked a few times.

"Knock, knock, knock!" A knock on the door blew in the bathroom.

But except for the sound of water droplets, no one responded, and there was a deathly silence in the single room.

The wooden door can only be locked from the inside, which means that there must be someone in the single room, since there are people, how can there be no movement?

Uncle Zhao was anxious, and had a premonition that something had happened, maybe someone had fainted in the bathroom, and similar incidents had happened before.

With all his strength, he slammed into the wooden door.

Public baths have been built for many years, and many places are not very strong, and this wooden door is no exception. Therefore, Uncle Zhao didn't spend much effort to slam the wooden door open.

In an instant, the pungent smell of blood permeated from inside.

When the flashlight beam hit the private room, the old man, who had seen countless winds and waves, fell to his knees in fright, and his feces and urine were messy.

In the narrow single room, it had long been submerged into a pool of blood.

In the middle was a naked woman, in an extremely ambiguous posture, half-kneeling on the ground, staring straight ahead with wide eyes.

Her fair body was full of scars from being abused.

There was a narrow scar on the bottom of the woman's neck, which almost tore most of her neck apart, and blood was dripping downwards at this time. And her two torsos were frighteningly bare, and the arms that connected the torso were cut off and disappeared.

In the corner of the single room, a transparent paper cup was placed, which was filled with blood, and on the white wall, a string of numbers was left with blood: 219.

......

The matter did not end like this, and in the next half a month, there were two more cases of rape and murder of a bad nature in Heijin City, the murderer followed the victim into a remote place, controlled the victim with violence, and forcibly had a relationship, and then killed him by cruel methods.

The two crime scenes were equally horrific and filled with a lot of blood. Coincidentally, after committing the crime, the murderer took away part of the victim's body and left blood characters at the scene of the murder, which were 319 and 419 respectively.

In these three rape and murder cases, the modus operandi is similar, the murdered women are always wearing red clothes, and the crime scene is complicated, it is difficult to extract useful DNA, and the missing parts of the limbs of the three victims have not been found so far.

The murderer singled out the women in red, and the methods of the crime were cruel and hidden, causing huge social panic. After cross-comparison by the police, it was confirmed that the three cases were committed by the same person.

Three cases, three lives! That criminal demon is still at large!

Due to the bad impact of the case and the possibility of the murderer committing the crime again, the police quickly combined the three rape and murder cases and set up the project as the 3.19 Heijin City Extraordinarily Large Homicide Case for investigation and investigation.

Later, most of these series of cases circulated in people's mouths as "black gold cases", and filled the headlines of major post bar websites.

The above are all versions circulating on the Internet, and you can get them in Baidu at any time, but next, what I want to say is what you don't know.

On the day I agreed to go to Lao Yan, he appeared at my door with a briefcase.

Lao Yan has always been a calm person, but this time he seemed to be in a hurry, he had been hurrying over, and the newly bought suit was completely soaked with sweat.

When I entered the house, I threw the briefcase in front of me and hid to smoke a cigarette.

The briefcase was stuffed with documents detailing the three rape and murder cases, as well as the course of the cases.

Although I have seen many bloody cases in the past few years in the police academy, after reading the documents, the whole person is still soaked in cold sweat.

I've been in contact with a lot of gangsters, even what people call psychopathic murderers, but their actions are nothing compared to the murderers recorded in the papers.

After staying up all day, I finally read all the documents, and my eyes were as uncomfortable as fire. Looking at Lao Yan again, he didn't sleep all night, and the cigarette butts in front of him were almost a small mountain bag.

Later, Lao Yan saw that I was almost done, so he spat out the mist and said lightly: "Tell me, what do you think?" ”

"The murderer is a murderous, level-headed guy with a certain amount of anti-reconnaissance ability. After the killing, the scene should be handled in such an orderly manner, and if possible, it is recommended to start the investigation with people with criminal records. ”

"I took the high-speed train for five hours, and I didn't specifically listen to you." Lao Yan extinguished the cigarette butt and shook his head in disappointment.

"219, 319, 419, these numbers, there is a problem!"

"Tell me, what's the problem?"

Judging from the photo, the number one is slightly tilted to the right, and the murderer even repainted the number 319, emphasizing the tilt to the right, making the number one in this group of numbers look a little strange.

Most people write one, not so deliberately. I speculate that the information that the murderer really wants to leave should be 2/9, 3/9 and 4/9! ”

"Go on, don't stop." Lao Yan suddenly snuffed out the cigarette, and his dead eyes were bright again. Obviously, what I was talking about was something he had never expected before.

Generally speaking, the traces left by the serial murderer at the scene will have a special meaning, in order to increase the satisfaction of his crime.

The most notorious criminal in history, Ramirez, known as the Night Sniper, is sure to leave an inverted five-pointed star on the scene as a symbol after the killing.

In my opinion, the three sets of numbers left at the scene are actually three sets of scores, and every time the murderer kills someone, the element adds one. The denominator 9 under it indicates the total number of people he wants to kill, a total of nine people!
