Criminal Investigation Notes - Chapter 122

Lu Jun never thought that Lan An’s confession would be so easy and smooth.

He repeated in disbelief: “You said, you are… fine sand?”

It is like a difficult problem that has been pursued for a long time and is about to be solved with great effort. Suddenly knowing that the answer is right in front of you, people can’t easily believe it.

Lan An seemed to have calmed down from the panic she was initially caught, she accepted the fact, lowered her head and said, “It’s me, I’m fine sand, since three years ago, I’ve been researching, making bombs, and having my accomplices make bombs. put it in the city.”

“Who is your accomplice?”

“Xie Qiu… Xie Qiu, who died in the explosion at the beginning.” Lan An said here and lowered his head, “Two years ago, I was cooperating with Xie Qiu. I was in charge of making bombs, and he was in charge of dropping them.”

Lu Junchi’s brows furrowed deeper: “Your main crime facts.”

“We drop bombs in the city every ten days.” Lan An said after a pause, “After he died, I didn’t do it again. Until recently, it happened that Yu Coco was harassed. Dong Anchen asked me for help and asked me what to do, and I gave him the bomb.”

She stared at a corner on the ground and swallowed: “I didn’t expect that the police would find us so quickly…”

Lu Jun thought about the sand lately. It seemed that she didn’t know that it was the sand that exposed her. He asked, “Why do you use the sand from the painting workshop.”

Lan An lowered his head and said softly, “I’m in the sand painting workshop. Instead of looking for other sands, I might as well use what I have at hand… Besides, these sands are my favorite…”

Lu Junchi and Qiao Ze didn’t speak for a while, they looked at the woman in front of them, thinking about the truth of her confession.

She said the name of understanding Qiu, even if she is not the murderer, she must be someone who has been paying attention to this case.

And a lot of what she said was accurate.

Lu Junchi stood up and handed Lan An a few pieces of paper and a pen.

He narrowed his eyes slightly and looked down at the woman in front of him: “Draw it, draw the structure of the bomb.”

This is the most direct, fastest and easiest way to verify the identity of fine sand.

As a bomber, if it was real fine sand, he would definitely be able to restore the structure of the bomb he made.

Lan An glanced at him, took the paper and pen, and drew with trembling fingers. Maybe because she was too nervous, the lines she drew were distorted, but even so, it could still be seen that she had a good foundation in art.

The prototype of the bomb was quickly drawn, and then she began to draw the details of the interior, and also made the logo on the outside.

Lu Junchi stood opposite her, looking down at the woman and the picture in front of her.

Qiao Ze sat in the seat, stretched his neck, and wanted to see what Lan An had drawn, but his position was a bit far, and it felt unethical to get closer, so he could only hold on and sit on the seat.

Time passed in seconds.

Su Hui rested his chin with his hand, sat in the observation room, and watched all this silently. His eyes were hazy, and he could vaguely see Lu Junchi standing beside Lan An, but he could hear the voice inside.

The interrogation room was extremely quiet, and only the sound of the pen tip touching the paper was transmitted to his headset through the radio microphone.

It was as if something was gently touching his eardrum, which was not deaf.

Su Hui knew that Lan An must not have been doodling. If she made a mistake, it would not have taken so long. Lu Jun would have stopped her sooner or later.

Lu Junchi is standing next to her now, quietly watching her drawing, there is only one situation, Lan An’s drawing is correct.

His inference was correct.

The images drawn by Lan An took shape for the first time, and then she began to make signs.

She pursed her lips, controlled the pen in her hand, and wrote graceful words beside her.

Lu Junchi had just listened to Zhu Baiyi’s lecture and knew the general structure of the bomb. What Lan An drew in front of him was the bomb that appeared in the accident.

Finally, she drew two lines and marked it next to it – “sand”.

That is the key position of the whole bomb, and it is the isolation sand layer of the reagent. Once the time is up, the sand layer leaks out, the two materials fuse, and the reaction proceeds, which will generate huge energy and explode.

The picture drawn by Lan An gradually took shape, and it was no longer necessary to ask an expert to confirm it. Lu Junchi could see that it was exactly the same as the bomb structure in the fine sand case.

The woman in front of her is really related to everything.

Lu Jun put away his pen and asked Lan An, “Where did you learn how to make it?”

Lan An said: “It’s my father… He used to be a blaster in the mining area, and he knew Qiu because of this. He has always been interested in making these things. When I was a child, he taught me how to make bombs.”

Lu Junchi looked at the woman in front of him: “Why do you want to kill those innocent people?”

Two years ago, so many people have died. Among them, there may be scum like Duan Siyuan, but more innocent people, and even a number of police officers.

Thinking of those people, Lu Junchi felt that his eyes were sore.

Lan An lowered his head and said: “Every time the location is randomly chosen by Xie Qiu, I just provide him with bombs.”

“You should know that what you provided him is dangerous and will hurt people’s lives, right? Without your help, Xie Qiu wouldn’t be able to cause such heavy casualties. These things are all related to you.” Lu Junchi increased his tone. ,”why?”

These three words, he is not only as a policeman to find out the truth and question the prisoners, he is also asking for the dead souls.

Lan An’s voice trembled: “There is no special reason. It’s just because… I hate them, they are all human, why do they live so easily and we live so hard. What I see every day is the helplessness of life. … Xie Qiu is sick, and the hospital can’t cure him … He naturally wants some people to accompany him to death.”

“There’s no one at all, it’s easy to live…” Lu Junchi said and sat back in his seat to calm himself down.

He opened his mouth and said: “Okay, you said that you are fine sand, then we will start the verification now. I hope you can retell your crimes clearly. When did you start, what did you do the first time, and the second one? The first time, the third time… How do you feel every time you see those news.”

Lan An raised his head when he heard this, with tears in his eyes: “I’ve confessed, isn’t it enough? I admit all the crimes. Is it okay? I admit it, I admit it, I did all those things. , your case is solved, just give me the list and I will sign it. The next step is the judgment of the law, isn’t it?”

As soon as Qiao Ze’s pen stopped, he didn’t know why, but Lan An’s obedience and cooperation from the beginning suddenly changed.

She obviously didn’t want to recall those details.

Su Hui was sitting in the observation room, looking at the situation inside, he suddenly stood up and pushed open the door of the interrogation room.

Lu Junchi was a little surprised by his entry.

Most of the time, Su Hui would not try prisoners in person. One was because of his status as a consultant, and the other was that he was better at sitting in the observation room, listening to their stories, and profiled the prisoners’ psychology. Also, Su Hui couldn’t see or hear clearly. The headphones in the observation room could help him capture more information.

But now, he appeared in the interrogation room, facing Lan An.

Su Hui didn’t sit down, but stood by against the wall. He said, “You don’t match my profile.”

Lan An was stunned for a moment, obviously not understanding: “What doesn’t match…”

“Profile.” Su Hui said, “Every criminal has his own psychological trajectory, just like those sand bottle paintings you drew. The paintings in each person’s heart are unique.”

Lan An lowered his head, his face becoming more and more haggard.

Su Hui asked her, “How many bombs did you give Dong Anchen?”

Lan An lowered her head and seemed to be thinking, and then she said in a trembling voice, “Two.”

“What color sand did you use to make the bomb for the first time.” Su Hui asked again.

“First time…” Lan An hesitated, her eyes were a little flustered, and then her lips moved, “It’s blue sand.”

Lu Junchi’s brows stretched out. Just now, he always felt that something was wrong, but he couldn’t find a breakthrough. But Su Hui asked two questions quickly.

The answer she said was wrong, the first time the sand was ordinary sand, and what they caught was not the real murderer at all.

The room was suddenly quiet, Lan An’s face changed, sweat dripped from her forehead, and she realized that she had answered wrong. She hurriedly tried to make amends: “I…I may have misremembered…”

The three police officers looked at her. It was impossible to remember wrongly. The first time a bomb was made and dropped, it was like the first murder. It was enough to make a bomber unforgettable for a lifetime.

When asked here, Su Hui stopped going around in circles. He looked directly into Lan An’s eyes and said, “Lan An, you set up a special painting workshop, and the work you do is only done by a person who has sympathy for others. Yes. You have been avoiding the topic of casualties from the beginning. Your indifference is fake, you can feel the pain of others, and you are not a person who will hurt innocent lives. “

This is the heart of the problem.

Lan An was not indifferent enough, not cruel enough. He didn’t know where she knew the internal structure of the bomb, but she couldn’t create the motive for murder out of thin air.

Now, Lan An is even more nervous than before. She bit her lip and digs the handrail of the interrogation room with her fingernails.

Su Hui said: “I asked you two questions. The first question, your answer is guessed. You know that there was an explosion, and then I ask you a few more questions, the answer can’t be one, you I feel that three is too much, so I try to answer two. I hope you answer the first question correctly, because it will give you a kind of inducement, you will think that my question is simple, and you can answer my question by inference You know we tracked you down through the sand, so when I asked about the color of the sand, you answered that person’s favorite color.”

Blue, for them, is not only a surname, but also has other meanings.

Lan An was struck by what he said, her lips trembling.

Su Hui continued: “He also used blue, but not as a beginning, but as an ending.”

“He used ordinary sand at first. As long as he kept using ordinary sand, it would be very difficult for us to catch him, but later, he switched to the colored sand from your painting workshop.”

“Maybe from a long time ago, this person has prepared a way for himself. Once he is discovered, he can throw the blame on you…or he has already made it, and you are willing to take the blame for him.”

“There’s a reason why he didn’t show up in those two years, and there’s a reason why he’s doing this again now.”

“Perhaps, he used the most unique peacock blue this time, so that we can easily find Shafang and find out about Dong Anchen and Yu Keke. The purpose is to catch you…” Su Hui’s voice was low and hoarse, he was useless Stern words, but every word he said was like a sword, poking into Lan An’s heart.

He is telling the truth…

There was fear in Lan An’s eyes, her teeth were touching and rattling unconsciously.

At the beginning of this inquiry, she was already mentally prepared to face her fate.

But now, she was shaken.

After talking about this, Su Hui lowered his head to look at her, his voice was slightly serious: “Lan An, don’t lie, tell me, who is that person, the person you want to protect?!”

Su Hui could feel that the person who made the bomb was ruthless and indifferent, and regarded life as grass, and it was absolutely impossible for the shivering woman in front of him.

He had been listening in the observation room just now, and at the end, he finally knew why something was wrong, it went well, everything went so well…

This kind of smoothness means that they have fallen into the trap of the murderer.

He must hurry up and get the truth from this woman.

Because maybe at this very moment, a new disaster is brewing in this city.

On the first floor of a building in Jiayu Community, two streets adjacent to Shahuafang, a figure stood by the window, raised the corner of the curtain, and looked at the street below.

It was a very small window, less than half a square meter in size, and it was separated by an iron fence. Even if the window was opened, there could only be a small gap.

That’s the only part of the room that can be illuminated by light.

He suddenly heard the sound of the door opening, and the smile on his face gradually became bigger…
