"Officer Liu, please go to the bedroom, I want to know more about the situation at the scene."

A slightly hollow voice came from the notebook, a machine-like emotionless tone that felt unreal.

"Okay," Liu Wenyu endured his nausea, held the notebook in his hand, and walked into the bedroom, "That...... W, I kind of want to go out and breathe, or ...... I'm looking for Officer Xu to take you to have a look? ”

"Whatever you want." On the other side of the computer, Wen Yifan looked at the picture he sent with an expressionless face, and narrowed his eyes slightly.

- The second case, which happened so quickly, was it a demonstration, or was it something else?

His eyes fixed on the photo in front of him, and he fell into deep thought......

The background of the photograph is simple, with a polished tiled floor against the white lights of the roof, a few simple photographs hanging on the wall, and a few plates of unrecognizable dishes on the table, which have long since rotted and grown some kind of rotten black spots.

But that's not the point.

The center of the photograph is given to the center of the living room, where four adults kneel, just like the previous scene.

They still knelt in circles, kneeling on one leg, holding a cradle made of bamboo in their four hands, their expressions distorted, their expressions full of pain and despair.

Their fingers are in the shape of chicken claws, their five fingers are curled up, their fingers are full of minced meat, and their nails have long been damaged by some behavior before their death, and their eyes are blurred with flesh and blood.

The most frightening thing is the impressive number of fatal injuries.

A neat and hideous knife cut extended down from the chest, revealing the flesh of a white flower, which had no internal organs, but a variety of brightly colored flowers.

Not only that, but their mouths and eyes are full of flowers, and the whole scene looks weird and reveals a little beauty.

Their entrails were hollowed out, and then they were neatly placed in cradles and lifted up by four men, like devotees offering sacrifices to the gods.

The most bizarre thing about the whole scene is that there is not a trace of blood on the ground, including their bodies, and there is not a single drop of blood left, just like pork that has been cleaned inside and out, naked to the air for everyone to admire.

At the scene, there was not a trace of blood, nor the slightest smell of decomposing corpses. The whole living room is filled with a strong fragrance of flowers, but it is this fragrance of flowers, coupled with this highly visually impactful crime scene, that makes people feel a deep sense of discomfort, and even for the police officers at the scene, the excitement and impact brought by this crime scene are even better than the first murder case.

On October 23, 2008, the second case of door destruction occurred.

However, a certain peculiar feeling made Wen Yifan feel a little uneasy, which was the disobedience he felt after writing about the murderer's psychology.

- Why is this arrangement?

"Officer Xu, please gather all the police officers in charge of this case, I want to talk about my speculation." Holding this trace of uneasiness, Wen Yifan said slowly, "This case has exposed a lot of things, although there are some deviations from my original speculation, but it is this contradiction that makes me better able to grasp the mentality of the murderer." ”

Ten fingers nimbly roamed over the keyboard, and soon typed out a large number of characters, which were quickly turned into pictures and sent to the other person's mobile phone.

"Please pay attention to the flowers in their bodies first, I have already sent them to you about the varieties of flowers," after a slight pause, he continued, "The flowers inside, by comparing the various kinds of flowers, I have found their corresponding varieties." ”

"The flowers that are in their mouths are oleanders and gardenias; The flower that pierced into their eyes was the Great Rock Tree; The flowers in their bellies, yellow roses, yellow hyacinths, hydrangeas, and fragrant oaks, look so irregular, but next, I will analyze the psychology of the murderer according to what they have in common. ”

"Oleander is an evergreen erect large shrub, up to 5 meters high, the branches are gray-green, the young branches are ridged, slightly hairy, the leaf surface is dark green, the leaf back is light green, the midrib is trapped in the leaf surface, the petiole is flattened, the inflorescence is apical, the corolla is dark red or pink, the corolla is single-petaled and 5-lobed, its corolla is funnel-shaped, the seeds are oblong, the flowering period is almost all year round, and the summer and autumn are the most prosperous; It is a perennial herb with oblate spherical tubers, very short stems on the ground, and the whole plant is densely covered with white hairs. Leaves opposite, hypertrophied, serrate; The flower is apical or axillary, the corolla is bell-shaped, with pink, red, purple-blue, white, compound color and other colors, large and beautiful. ”

"Hydrangeas, whose scientific name is paraffin red, is an undefeated potted flower with a long flowering period. If it is kept at a certain room temperature, it will bloom all year round; Five-fingered mandarin is the fruit of bergamot, a small evergreen tree or shrub plant of the Rutaceae family, is a variant of citrus citron, the top of the fruit is cracked into a finger-shaped, flexion and extension are different, the length is uneven, it resembles the hand of the Buddha, so it is called 'Buddha's hand'. Bergamot is also called 'Mi Luo Mandarin', 'Fu Shou Mandarin', 'Bergamot Oak', etc.; and the rest of the hyacinths and roses are the daily flowers of the family, I may not need to introduce too much, but these are not the point, the point is - what do they all contain the meaning of the murderer? ”

"Thinking about it from this point of view, maybe the reason why the murderer chose these flowers was because of their flower language, and it just so happened that for some reason, I also knew a little bit about these, so I quickly understood the inner world of the murderer - I think you also almost understood, yes, it is the language of flowers."

"The flower language of the peach-colored oleander in the mouth is curse, and the flower language of the gardenia is generally considered to be eternal love and agreement, but it obviously doesn't make sense on this occasion, so I think it should be taken another meaning - deception, so that the reason why the two flowers are put in the mouth, everyone should understand."

Subsequently, the flower that pierced into the eyes was the Great Rock Tree, and its flower language was lust or beauty, and in combination with the place placed by the murderer, it should mean the former; Finally, among the four flowers that fill their entire bodies, the negative flower language of yellow rose is unchastity, the negative flower language of yellow hyacinth is jealousy, and the negative flower language of hydrangea and fragrant oak are betrayal, fickleness and poisonous beauty respectively, so that the murderer's intentions should be very clear. ”

Clearing his throat, he glanced at Wen Qingyu, who was taking notes carefully beside him, and continued: "That's right, the murderer is humiliating and belittling everything about them, so it seems that what the murderer wants to say is: 'They are sinners, they are the garbage of this world, and they are the people who deserve to be cleaned up, therefore, my actions are righteous, and it is because of me that their sins are exposed'?" ”

Tapping his fingers on the table, Wen Yifan thought for a while, and immediately changed his words: "No, if this is the case, then the murderer should also be counted as a person who should be executed for 'misconduct', but the whole scene did not give me any feeling of judging others from above - even if there were, it was not from arrogance towards myself, but like a kind of piety." ”

"So, I think that the reason why the murderers put their entrails in the cradle may also be connected with the first case: the Son of God has come, and those sinners who are hidden in the world should dig out their own human chests, expose all their sins, and sacrifice themselves as sacrifices to the Son of God with supreme piety."

"In this way, everything can be explained, including the wear and tear on the fingernails of the four people."

"I see, in this way, this case can indeed be handled in conjunction with the first case." Xu Wenxin nodded, and then said: "By the way, Mr. W, another small poem appeared at the scene, which was written on a note by the murderer and placed in the cradle, I'll help you shoot it!" ”

Staring at the image coming from the display, Wen Yifan fell into thought.

Challenge the gods through the Infinity Garden

That's the hell called Virginia

Flowers laugh at the ignorance of the blasphemers

The arrogant will burn in hell

- Sure enough, as I thought, this is indeed a challenge to someone or a group, "Hell in Virginia", is it implying that Layer 8 encryption is being used, using the Virginia cipher?

INTERVIEWER So, with this information, how much should it be shared with the police?

After a moment's thought, he spoke: "In this way, it is almost certain that the eighth layer of the murderer used the encryption method of the Virginia cipher. ”

"In a Caesar cipher, each letter of the alphabet is offset by a certain offset, for example, when the offset is 3, A is converted to D, and B is converted to E...... The Virginia cipher, on the other hand, consists of a number of Caesar ciphers with different offsets. In order to generate a password, the tabular method needs to be used. It contains 26 lines of the alphabet, each offset by one place from the previous line to the left. The exact line of the alphabet to use for compilation is key-based and constantly changes in the process. ”

"For example, if I want to encrypt the word 'flower' with the Virginia cipher, and my key is 'murder', then the encryption process is the following process: the letter of the plaintext is 'f', and the letter of the key is 'm', and because among the twenty-six letters, f=6, m=13, then the ciphertext is 6+13-1=18, and the letter 'r' is obtained, and so on, you can get the ciphertext 'rffzii', it's that simple."

"However, perhaps everyone has also discovered that this time, the murderer only hinted at the encryption method, but did not write the key, which means that the real key needs to be calculated by ourselves based on the information in the poem, in other words, the Virginia code cannot be deciphered if it lacks the key, so the primary goal now is to find the key."

"So, you mean, the key is hidden in this poem?" A policeman asked.

"Not only that, but the key may be hidden in any detail of the house, and although it is most likely that the poem contains the key, it would be bad if the murderer caught us, so please don't give up any unusual detail in the house, or you may miss the murderer." Wen Yifan replied affirmatively, "However, compared to the secret key, there is another detail on the scene that I care about very much." ”

"What's that?" Xu Wenxin asked.

"It's very simple, I don't know if you have noticed, compared to the first scene, this time the scene is a bit too neat?"

"In the first scene, blood was pouring and the house was extremely messy and full of the smell of decay, maggots and some beetles kept coming out of the corpses, and the scene made it impossible to get off the ground, and the bodies of five people had already begun to decompose. But I would like to ask you to take a look around you, why is the second scene so neat? ”

"I think it's an escalation of criminal modus operandi," Liu Wenyu said suddenly at this moment, "as we all know, almost all serial murderers have this characteristic, that is, the further escalation of criminal modus operandi, whether it is brutality or high intelligence, there is this law." ”

"It's quite an interesting idea, indeed, after committing the first case of a series of homicides, the perpetrator will have an obvious consequence assumption, that is, he has completed the denormalization, as long as he is not arrested, then every case carried out after that belongs to a satisfying "excessive gain", which is similar to the psychology of "can do more together to earn", which is extremely stimulating for the offender under the domination of the anti-social personality, and will produce a steady stream of criminal motivation, that is, "the punishment is limited, But my crime can be unlimited", which played an important role in the deterioration of his criminal psychological structure and criminal behavior. ”

In more cases, he will have a learned effect, gain criminal experience, and at the same time reminisce about the process of crime, thinking about "where can be done better", which is actually laying the groundwork for the next more serious crime; And his criminal psychological structure will continue to develop in a certain direction, and it will need to acquire more content than just committing a crime against the victim. ”

"But I think the murderer isn't just that, because he doesn't fit those views."

seems to feel everyone's doubts, Wen Yifan explained one by one: "First of all, please look at my first point of view, it should not be difficult for you to find that it is a feeling of self-abandonment, as if it is a mentality of 'kill one more and you will earn', but looking at our two cases, it should not be difficult to see that the murderer did not have this emotion, but from the beginning when he killed the first person, he had already planned the next action, which can be seen from the password and poetry." ”

"Then there is the second point, which is mainly about the aspect of high brightness, at first glance in these two cases, the murderer's methods have indeed improved, but if you dig deeper, you will know that no matter what the murderer made the scene look like, he did not leave any traces, nor did he make any noise, and even the surveillance video did not lock on to a certain suspect, so there is no high-brightness improvement, because he was very clever in the first case."

"And finally, the third point, obviously, I don't see any increase in his cruelty, and even compared to the first case, I even feel that his cruelty has decreased, which is why, I don't think it's a sign of an increase in criminal methods, because the way he showed it from the beginning, it doesn't need to be improved anymore."

"I'm more inclined to the above than the above point of view - the murderer seems to be trying to get someone's attention."

"Attention?" Xu Wenxin exclaimed, "You mean, the reason why he committed these cases was just to attract the attention of others?" That's too mad, isn't it? ”

- It's like the kind of monster you talked about, Mr. Wen......

"The criminal we are facing this time is likely to be this disgusting 'monster'," as if noticing the change in her tone, a sly smile appeared on the corner of Wen Yifan's mouth, "That's why he arranged the first case so panickingly, he just wanted to cause an uproar in the police world, so that someone or an organization could notice him...... So, did he still ask for the password to be published in the newspaper? ”

"Judging from the scene this time, no." Liu Wenyu replied.

"Then everything can be explained, in the second scene, he not only cleaned the blood to avoid decay, but also stuffed the flowers at the same time, put a lot of activated charcoal into the bodies of those people to absorb the odor, even in the cradle, which is not intended to add beauty to the whole scene, making it more like a work of art, rather than a 'hell' made by some madman, in a sense, this scene is closer to his inner world."

"And the reason why he changed the modus operandi can be related to the fact that he did not ask you to publish the password in the newspaper again; That's right, these reasons seem to point to the fact that the person he wanted to get attention to is now attracted. ”

"Can this person, or this organization, be locked in by what has happened recently?" A criminal policeman with a physical evidence bag in his hand immediately asked, "If that object can be found, there will undoubtedly be a great breakthrough in the detection of the case." ”

"It's too simple, please note that about the first case, the wording I used was 'causing an uproar in the police community' - because the scene was too brutal, although it could indeed attract the attention of most people, but nine times out of ten, the information would be blocked to avoid panic, and the criminal let the password be released instead of the whole case, which may mean that he did not intend to let ordinary people outside the police community get the news at all, so it can be inferred that the object of his desire to attract attention is the police community, Or someone inside the police community, or at least someone who can get through the blockade. ”

"And after that, he asked you to publish the password on the seventeenth, but apparently we didn't do that, and it's puzzling that he didn't ask for it again, and it was evident that either he had a change of heart, or after that, the person he wanted to draw attention noticed the password—and from this it seemed clear that he had access to inside the police."

"Therefore, the subject should have access to internal police information, possess sufficient ability to crack the code, and after 17 days, obtain the code and the corresponding specific details......"

The words came to an abrupt end, and at some point, a terrifying conjecture exploded in his mind, and a possibility inevitably came to his mind.

- ...... that meet these three characteristics Looks like me......
