"At the end of the day, if every victim were like me......"

Coco looked at the screen on his mobile phone, and the corners of his mouth unconsciously showed a smile, "That's good, the righteous fighter Xiao Xu." ”

"Ahhh On the sofa opposite her desk, Xu Wanli was trying to bury her face in the pillow and sofa cushions, making a muffled protest sound, "The ghost knows that it will be photographed, and it will be transmitted to the circle of friends and Weibo, how will I see people in the future?"

Coco pursed the corners of her mouth and held back a smile, "In the current era, being photographed is nothing," Coco paused deliberately, "Being uploaded to the Internet and reaching more than 40,000 retweets a day is called awesome, this is a bright road that is about to become an Internet celebrity, Xiao Xu." ”

"Ahhhhh I'm going to kill me! ”

"It's not enough to kill you, tens of thousands of words of review at most, and ah, the sofa cover hasn't been washed for a year, and your dear cousin Mr. Zhou Daxuan likes to sit under his ass the most, and he always farts......"

Before he finished speaking, Xiao Xu had already jumped up, angry and ashamed. Facing Coco with a wicked smile on her face, all kinds of emotions are strung together, making her pull her hair almost crazy. "You, you, why are you so bad! Join the whole world to bully me! ”

Coco walked to the table, and the freshly boiled water on the electric kettle was flushed into the cup, rising a sweet cocoa flavor, "How dare you, classmate Xu, please stay calm, I have no plans to change the table recently." ”

Xu Wanli pouted, puffing up the small universe of anger, but unfortunately this emotion didn't have time to last for a few seconds, and it was occupied by another unique and great emotion, which is called fear.

The screen of her mobile phone lit up with the director's text message: Come to my office, immediately.

Xiao Xu felt a hint of murderous intent from the tone of this very unfriendly text message, and wanted to hug Coco's thigh to beg for life and death together, but Xun Keran, who was holding the mug, immediately opened the door to see off the guest, and waved a small handkerchief to wish her a smooth journey.

With the mentality of seeing death as home, Xiao Xu pushed open the door of the director's office, bowed his head all the way, admitted his mistakes, and "leader...... I know it's wrong~"

On the opposite side, there was the director's hilarious voice, Xu Wanli looked up and saw that there was not only one director in the office, but also a middle-aged woman who looked kind.

"Xiao Xu, when did you also follow those bad boys to learn thieves, come up and admit your mistakes first no matter what happens, haha?" The director teased, and there was no sign of anger on his face.

The middle-aged woman stood up and stretched out her hand, "Hello, I'm Fan Yuzhen from the Sex Crime Section, ...... your video"

Hearing the words in the video, Wanli's hair was almost on end, and she couldn't help but look at the director's face, but she still saw the cunning old fox with a ridiculous face.

"Hehe, don't be nervous, we're not trying to criticize you," Fan Yuzhen couldn't help laughing, "Your video has caused a lot of impact on the Internet, we actually want to ask you to work part-time and make a promotional video." In fact, every month of the year, there are some cases on our side that end up being let the criminals escape justice because the victims can't stand the blame of public opinion and society. What you said in the video is exactly what our entire department wants to convey to the whole society. ”

The heart that had been hanging was put down, and Xu Wanli suddenly vividly understood the meaning of the word crying and laughing.

"You don't want to?" Fan Yuzhen asked with some apprehension, "Of course, this is a request of ours, and it is not mandatory to ......."

The old fox director's slightly smiling eyes narrowed, "Xiao Xu, it seems that you still like to write reviews?" ”

"Who said that! I'm always willing! Xu Wanli's eyes widened, causing Fan Yuzhen and the director to laugh.

The old fox chief smiled, "Willingly, the police academy still has to deduct the money from your salary if you ask for compensation for the table." ”

"Huh? Don't—" Xiao Xu pouted in protest.

"You smashed someone's yard and didn't pay compensation?"

If it weren't for the politeness, Fan Yuzhen would have laughed badly, "It's okay, it's okay, we'll compensate, count it as ours hahaha." ”

"It's good to lead you!" Xu Wanli's eyes lit up, and she held Fan Yuzhen's hand and shook it hard.

Hmph, the old fox director is blowing his beard and glaring in his chair, all of them are little traitors with no conscience.

――――――――――――――

Over there, when Xiao Xu was experiencing the ups and downs of life, Coco was alone in the office. In the quiet space, only the electric kettle makes a slight boiling sound of gurgling, and the warm aroma molecules of cocoa milk tea diffuse in the air, Xun Keran looks down at the documents coming out of the printer, in the small office, it is quiet as if time has suddenly slowed down, and the world full of noise and strife outside the window is another space and universe.

A very strange substance was extracted from the hems of two coats in Zeng Ying's wardrobe, and the report sent by the university laboratory had a series of professional chemical names that even cocoa was not familiar with, forcing her to search through various scientific databases on the Internet to learn that this was a trace particulate matter after cigar burning.

Does Zeng Ying smoke? Xun Keran does not recall seeing similar information in any of the records or on-site inspection reports. But even if she smokes, or the people around her smoke cigars, why does it only touch the hem of her coat? The hot water in the electric kettle was gurgling and boiling, and Coco had a conjecture boiling in her mind, and she knew that every time she had a meeting in the big rope or the criminal investigation team, she would come home with the smell of smoke on her clothes. On one occasion she noticed that a scarf in her home also smelled of smoke, but it was a scarf that had not been worn in a long time on a chair, and no one smoked in the house...... It wasn't until a few days later that she suddenly figured out that the scarf was covered by a coat that smelled of smoke, which meant that some of the gas particles would be contaminated with other fabrics through various indirect contacts.

There has long been a saying in the forensic profession that any form of contact will inevitably leave evidence, which may be so small that it must be detected with various magnifying glasses and microscopes, but contact is contact, as long as you have been to the scene, the hair that falls unconsciously, the mud that rubs against the trouser legs, the secretions that cough spray on the wall, and the wall that passes by will hook off a trace of the fiber of your clothing.........

You've been here, you've been here.

Although this is an idealized contact theory, Coco has always believed that there is never a case without evidence, and the difference is only whether there is missing or undiscovered evidence.

She guessed that the cigar-scented particles only stayed under the hem of the coat because the killer was hiding in the closet, just like she simulated that day, squatting at the bottom of the closet, only touching the hem of the coat, and for a long enough time. This thought went around her mind several times, and finally decided not to tell anyone, because this chain of evidence is not so closed and powerful, and the biggest difficulty at hand is to find the location of the murderer, or where Qian Zixuan is, not to verify this kind of thing......

In the sudden flow of thoughts, Xun Keran was stunned, and her unconscious gaze happened to see the bottom drawer of her sideboard revealing a side. This cabinet is very old, and each drawer itself will automatically close slowly with a slight force, but the bottom one is old and needs to be manually pushed again to close completely.

But the bottom drawer doesn't fit properly.

Xun Keran was silent for a few seconds, quietly got up and locked the office door, turned off the lights, put on gloves, took out the ultraviolet lamp, and walked to the cabinet to observe carefully.

Each drawer handle is clean and free of fingerprints, as if someone has wiped it all over again.

The hygiene of the physical evidence and forensic medicine department is cleaned by the department's personnel in shifts, and it cannot be caused by cleaning.

Thinking of this, Xun Keran remembered the keyboard at home that was once "spotless", and this cold feeling of being quietly watched touched her nerves and made her back spine feel faintly chilled. She couldn't figure out why someone was spying on or snooping on her computer and files, there were no particularly sensitive cases recently, and it didn't look like the behavior of Fang He's group, who was it......

Xun Keran walked slowly around the room, and the originally quiet office was cold and unusually cold because of the change in her mood, which also made the shocked brain cool down quickly. She re-examines the cabinet and finds that the drawer design features a small half of a fingerprint on the inside of the drawer handle groove, which is mostly a blind spot for those who have not noticed. Out of luck, Xun Keran found a tool, carefully lay down in front of the cabinet, held his breath, and extracted half of his fingerprints from the inside of the drawer groove little by little.

The transparent cellophane showed clear lines against the sky light outside the window, and Xun Keran squinted at this half of the fingerprint, and could almost tell that it was an index finger fingerprint. But at the moment, she was more concerned about another thing: after finding that the keyboard at home had been wiped clean of fingerprints, she also extracted half of the fingerprints from the corner of the armrest of the chair. Over the past few days, she had repeatedly observed the half of the fingerprint, and could only conclude that it belonged to the lines of the index finger. Thinking of this, Xun Keran rushed to the table quickly, took out the half of the fingerprint that was sandwiched behind the cover of the notebook, and tried to close it with the half of the fingerprint on his hand.

Under the magnifying glass, the upper and lower lines are harmoniously connected into one, becoming a complete index finger fingerprint.

This coincidence of not knowing whether it should be said to be predestined or something gave Coco a very strange feeling, on the one hand, she felt that the world was unexpected, and on the other hand, she felt as incredible as winning the jackpot for this unexpected discovery.

There is a saying that people are doing it, and the sky is watching, once she didn't believe it, but now she feels that everything may not be.

She sat silently on the sofa and called Su Xiaozhe on WeChat, asking him to send the two halves of the fingerprints to the physical evidence class for identification and comparison.

"You just go to Wang Tao directly, don't give anyone else, and don't tell anyone."

Xiaozhe's face was full of curiosity, "Then what if Teacher Wang also asks?" What kind of case is this? How do I register? ”

"Let's just say that I'm mysterious, secretive, sneaky, but very important."

Su Xiaozhe was even more stunned by Xun Keran's answer, but he explained it like this, and it was estimated that he couldn't ask anything else, so he had to empty his head and turn around to carry out the task.

"Wait!" Coco suddenly called Xiaozhe and muttered for a long time, "No, don't hide it from others, you go around, take the elevator, and try to mention this matter to people as much as possible." With a gloomy tone, Xun Keran narrowed his eyes slightly, and a bottomless smile appeared at the corner of his mouth, "The more, the better......"
