Criminal Psychology

Of course, a good store cannot be stolen for no reason.

It is even more impossible for such a good surveillance video to disappear from the computer for no reason.

The only possibility is that someone has cleaned up all possible clues before the crime happened.

"How many days ago?" Xing Conglian grabbed the poor employee and asked carefully.

"Three... three days ago, yes, three days."

"It's the day before the teacher's birthday party." Lin Chen's expression changed slightly.

If the previous investigation made him feel as if he was groping in the dark and couldn't see where they were, then of course the situation is still dark now, but he suddenly realized that they had actually been staying in a tight cage. In the pocket, someone has already tied the mouth of the pocket tightly, and their struggle is only within a very limited range.

"Before the children under the banyan tree committed suicide, the other party had already started to erase the evidence, so they were well prepared." Xing Conglian didn't show any dejection, he even thought it was a matter of course, "Oh, No, this cannot be said to be adequate preparation, it should be said that the fundamental purpose of all this is to destroy the corpse?"

An organization that has been hidden for several years, using students to carry out countless dark businesses and make huge profits, it operates so low-key, why did it suddenly make big news about those mass suicides?

They should know better than anyone else that once they surface, there is no turning back. No matter what their ultimate goal is, as long as it is a major social event, the police will always pursue it to the end. It is only a matter of time before they can be thoroughly investigated. ...

Well, what Xing Conglian said was not wrong. The six students who died, including his junior junior sister, were just discarded as burdens. It seems that when they deal with those videos, there is probably nothing more important than "deleting" them directly. It's a neat way.

So all of this is a means to clear the evidence that the entire organization once existed, but even so, they still don't even forget to use this last chance to make money, which probably cannot be summed up simply by being cold-blooded.

Lin Chen suddenly remembered the question about Dynasty.

Have you ever seen a very evil world?

Really, too sharp a question.

He rubbed his face vigorously, as if the brief darkness could make people wake up.

Then, he heard Xing Conglian's voice in his ears: "Let's go, let's go to the store."

The young man's voice was so calm and calm, without any frustration of being preempted.

"I have sent Dynasty over to see if the monitoring can be repaired, but three days have passed, the possibility that the hard disk has not been overwritten is very small, and they will not be so careless in doing things, and they must be prepared not to get it back. "

Lin Chen nodded, and took a last look at the starred shop on the floor plan.

It's not much different from what I imagined.

The empty coffee bar is not big, it is located in the corner of the entire underground shopping mall, it looks like a cold beauty isolated in a corner, in fact, the shop is indeed too cold now.

Its glass door is closed, and the shop is dark. The light from the aisle illuminates a piece of log-colored floor near the glass door and the wooden bar counter that cannot be disassembled. The bar counter is empty, not even a single leaflet, no matter how you look at it , as the management said, the store was "stolen" and there was nothing left.

Except the shop sign is still there.

It was a very small piece of wood, hung on the door lintel, with an English letter written in cursive script on it.

Lin Chen frowned, then subconsciously looked at Xing Conglian.

"French, meaning knowledge."

The captain of the criminal police has made another contribution with his outstanding language skills.

Lin Chen lowered his brows in thought, and unexpectedly felt a slight smile behind him, he turned his head, and saw Su Fengzi glanced at Xing Conglian and then at him, his amber eyes were full of teasing.

"Why are you still here?"

Lin Chen asked angrily.

"Hey, the police are handling the case, and the crowd is not allowed to watch?"

Lin Chen felt that he could not communicate with him at all.

At the entrance of the coffee bar named "Knowledge", Xing Conglian turned on a flashlight and looked into the shop. There were ridiculous iron nails on the wall where the photo frame used to hang, and only the chandelier hanging from the ceiling remained. A few chains, light bulbs and lamp shades are gone.

"I've never seen such a hungry thief in my life." Xing Conglian said with a sneer, "If I call someone from the forensics department, do you think I can't even find a single fingerprint on the wall?"

"Yeah, it's too clean." Lin Chen returned to him, looking at the glass door without even a single fingerprint.

"What the hell is in this store? You have to go to great lengths to clean up all possible clues, and leave us no chance?" Xing Conglian complained nonchalantly, then squatted down and put on gloves , simply checked the door lock.

The lock cylinder does look like it has been violently dismantled, which shows that even if the other party is acting, he is very meticulous and thoughtful.

"Actually, you can probably guess that it's nothing more than records of people entering and leaving, some leaflets, and even this store may be responsible for releasing tasks..." Lin Chen leaned on the wall of the opposite store, watching Xing Conglian Survey the site and say, "It would be great if there were monitoring records."

"Yes." Xing Conglian raised his head and pointed to a black drop-shaped camera on the southeast corner of the store, "It's just that we can't see it."

"How likely do you think it is that the camera is still working and they have discovered that we found this store?" Lin Chen asked.

"The possibility of operation is [-]%." ​​Xing Conglian looked at the red dot on the camera, "However, luck is better, we are monitoring the blind spot now, if we don't enter the door, they can't find us."

Although he said so, he became more careful when he stood up.

After checking the door lock, Xing Conglian began to check the outer wall of the store. His hands in rubber gloves stroked the wall, and then stopped on an iron hook.

He turned on the flashlight again to make the light white wall clearer.

Under the strong light, you can clearly see that there is an area on the white wall that is lighter in color than other places, as if there are traces left by hanging something for a long time.

"What did you just say?"

"Which one are you asking?"

"Is it possible to guess what?"

"This store?" Lin Chen looked at the light-colored area, thought for a while, and said, "First of all, its purpose is of course to attract those potential targets to take the bait. With regard to the function of releasing tasks, I mean if it has a wide range of businesses, there must be an internal and external window..."

"For example, a publicity board?" Xing Conglian's fingers brushed the outline of the light-colored area, which happened to be the size of a common children's blackboard. "What thief would even steal the publicity board at the door?"

"This is too..."

Lin Chen didn't know how to describe his feelings.

While he was in a daze, Xing Conglian turned around and pushed away the jewelry store opposite the coffee bar.

It was already closing time, and the female owner of the jewelry store was closing the window and preparing to close the stall.

Xing Conglian showed his police badge, and then began to ask about the details of the shop opposite.

"The store opposite seems to have closed three days ago, and no one has been there since then..." The female boss brushed her temple hair, then lowered her voice, and approached Xing Conglian and said, "I suspect it won't be able to continue. , escaped on purpose."

"Oh?"

"Who comes to drink coffee underground for nothing? The business is so bad that sometimes there is no one there for a day, and their shop assistants are all weird, so aloof!"

"Qing Gao?"

"Yeah, I think it's the right door. Do you know each other? It's the first time I've opened a business. I went to order coffee from them. Why don't you give me a discount and have a better attitude? Their waiter treats me I don't care about it, I sat for a while and left, and I will never go again..."

The female boss probably had a long-standing resentment towards the neighbor across the door, so she began to chatter.

The difference in attitude is completely understandable. After all, the female boss is definitely not the one that the organization wants to recruit. Lin Chen decisively interrupted the other party's complaints and asked: "The property management said that they still sell books in the store. Do you still remember? Roughly what kind of book is it?"

"How do I remember, I've only been there once."

"Since you left after sitting for a while, there must be something that made you feel uncomfortable. Maybe it's not just the attitude of the clerk, maybe there are other reasons?" Lin Chen followed the advice carefully.

"If you say that, it's those books..." The female boss narrowed her eyes, lost in memory, "Anyway, it's quite embarrassing to read, it's all chicken soup for the soul, not even a normal magazine!"

"Chicken soup for the soul?"

"Oh, it's the kind of 'change yourself in ten days', or something like 'beautiful inspirational life'."

Lin Chen nodded, pointed to the outer wall of the coffee bar and asked, "Is there anything hanging there?"

"There is a small blackboard hanging, and there is one at my door."

Hearing this, Lin Chen glanced at Xing Conglian.

The captain of the criminal police took out his notebook, wrote a few words, and asked, "Perhaps, you still remember what was written on that blackboard?"

"Mr. Police Officer, I really can't remember this, who cares what they wrote!"

Lin Chen felt that Xing Conglian looked at him inquiringly. Although Xing Conglian didn't speak, Lin Chen could roughly guess that he was asking, "Can this memory be awakened?"

Lin Chen shook his head.

Xing Conglian tapped on the notebook and asked again: "Then roughly, what will be written on it, you can say whatever you think of, don't need to be too specific."

"Probably, there aren't any today's specials, free for students, takeaway calls..."

"Can I understand that the above is a price list that will change?"

"Of course it will change, but it's kind of weird..."

"how?"

"It can't be said that it's strange, there are always people looking at the blackboard at the door... and don't go into the store, just look at the blackboard..."

"What kind of person is it?"

"What else can I do? Aren't all the people coming and going here are students."

Lin Chen looked back at the iron hook and the gray and white outline on the opposite wall.

A blackboard, students standing still, the erased monitoring of Area D...

The content written on the blackboard may be more serious than they guessed.

He can almost imagine that every morning, the clerk puts on his uniform, glances at his mobile phone casually, then slowly puts on his apron, opens the door, picks up the chalk on the blackboard, and writes "Today's Special Offer" or something else words.

In the eyes of ordinary people, those characters may be slogans that determine whether they go in for a cup of coffee, but in the eyes of others, it may just determine the life and death of some people.

Students don't even have to enter the door, just pass by the door occasionally to know exactly what they are going to do.

This approach is so leisurely and calm, but it is so cold-blooded that it makes people tremble all over.

Lin Chen took a deep breath, hoping that all this was caused by his too rich imagination.

Xing Conglian also seemed to think of something, put down his pen and said to him: "You won't be the same as I guessed, will you?"

"What did you think of?"

As soon as Lin Chen asked, he was dragged to a corner by Xing Conglian.

"It's a bit exaggerated, but we now have a codebook. If they are really bold enough to write the instructions on the blackboard, wouldn't we know what the organization asked the students to do?"

Lin Chen was amazed at Xing Conglian's thinking.

"Discrete Mathematics" is a codebook and speculation, and the organization that transmits various commands to students in an encrypted form is also speculation. The only way to prove these speculations is to find a definite instruction, which is what they are missing now. thing.

Maybe occasionally someone will take a photo of the entrance of this coffee shop?

Maybe someone remembers what was written on that blackboard?

But that was tantamount to finding a needle in a haystack, they were still one step too late after all.

"If there is a camera in this store, it will be fine to monitor the blackboard 24 hours a day." Lin Chen said almost helplessly.

"There are in this store." Xing Conglian is probably a man who has a deep understanding of the camera. He casually pointed to the very inconspicuous camera in the corner of the store: "How can we open a store without installing a camera?"

As he spoke, he walked directly under the camera, and then looked around. There are large and small glass mirrors hanging everywhere in the jewelry store, and even the back of the window is mirrored, so the room looks bright.

Suddenly, Lin Chen saw that Xing Conglian's gaze stopped. Lin Chen followed his gaze and found that Xing Conglian's gaze fell on a floor-to-ceiling mirror.

"Go and open the door."

Xing Conglian's voice suddenly became very calm, and Lin Chen opened the door as promised.

The captain of the criminal police raised the corner of his mouth and said, "Tell me, there are so many mirrors here, how likely is it that one of them will accidentally shine on the small blackboard opposite?"
