"Boom"!

A loud bang came from the front of a bank.

Of course, this boom was just what I imagined at the scene of the explosion.

However, this is not a simple imagination, this loud noise has been 100% seen. Because just an hour ago, there was a big explosion in front of this bank.

Due to the fact that the area is in a high-traffic area, the explosion killed 2 people and injured 12 others.

At this point, I was already standing at the point of the explosion. It can be seen that a pit with a diameter of about one meter and a depth of about 40 centimeters has been blown out of the concrete floor. The glass doors and windows of the bank were also blown up, which shows that the power of this explosion is really not small.

I checked the scene and found that the explosives were detonators or something, but not just detonators, but also some mixtures, such as C4 and other explosives.

Then it is certain that this explosion was absolutely man-made.

When Lao Lu and the others went to retrieve the bank and surrounding surveillance, I continued to observe the scene.

I found a cement bag left at the scene, and at the point of the explosion, there were also some scattered cement blocks.

This is a sidewalk, and the sidewalk is paved with bricks, but why are there cement blocks that are so different from the bricks?

I speculate that the cement was brought by the murderer, and its purpose was to bury the bomb and seal it off on the ground outside the bank.

In the dead of night, the killer dug up the ground in front of the bank, planted the bomb, and sealed it with cement.

Once the bomber's modus operandi was understood, he had to investigate his motive for dropping the bomb.

I spoke to a bank clerk at the scene, who told me that the bomb exploded at the same time as the cash truck was transporting cash to the bank. When the bomb exploded, one cash carrier was indeed killed, but the cash box was in the hands of another injured cash carrier, and the cash was not taken.

If, as the bank clerk said, then the purpose of the explosion was to rob the cash from the bank's cash truck.

It can be seen that the nature of this case is extremely bad.

From this bombing, I deduced several characteristics of the murderer.

First, there is such a large bag of cement on site, and to transport this bag of cement, it is obvious that there is a means of transportation, such as a motorcycle or a car.

Second, the murderer must have blasting technology and radio remote control technology. Because this bomb is obviously a man-made remote-controlled bomb.

Third, the murderer must have appeared at the bank in the middle of the night, and the location where the bomb was planted could have been filmed by the bank's surveillance. The murderer's audacity in planting a bomb under the surveillance probe shows that he was bold, and of course, I believe he must have done some camouflage.

Based on these three points, I launched an investigation.

In the criminal investigation team, Lao Lu collected surveillance footage near the bank. Of course, the most important thing is the bank's own surveillance footage.

Since it was night, the surveillance video was very blurry, but we still checked the surveillance video very patiently.

At 3:05 a.m. before the bombing, a white motorcycle stopped on the road in front of the bank. A man got off the motorcycle, and although the surveillance was vague, it could be seen that the man was wearing a white motorcycle helmet. He looked at the surveillance camera, but we couldn't see his face because he was wearing a black mask.

It's December, and it's very cold. So the person in the surveillance is wearing a lot of clothes and looks a little bloated, so it is impossible to tell whether his body is thin or fat.

After the man got off the motorcycle, he first brought down a box tied to the back of the motorcycle, and then took down a large bag from the motorcycle.

The big bag, I'm sure, was the cement bag. The box, I guess it's a bomb in it.

The suspect then began to dig into the ground with tools such as shovels. Soon, he pried open the bricks in the ground and dug a small hole.

When the pit was about the size of the pit he had dug, he opened the box and took out the contents of the box and put it in the pit, then covered it with soil and sealed it with a layer of cement. I think the purpose of his sealing of the cement was to prevent other people from digging the place. But that's obviously a bit of a stretch. Of course, everyone's mindset is different, and it makes sense that the murderer thinks it's safer to do so.

After the bomb was cleared, the killer set aside the bag of cement and placed a barrier next to the cement. It seems that the murderer was trying to create the illusion that construction is going on here.

It can be seen that the murderer's criminal thinking is very meticulous. An entire pavement is suddenly dug up and cemented the next day, which is easy to arouse suspicion. But if this place is set up as a municipal construction site, then the suspicion will be greatly reduced, and no one will come to destroy the place where he set up the bomb.

So since this is a remote-controlled bomb, the murderer must have been in the vicinity of the bomb before the bomb exploded.

So we looked at the remaining surveillance videos.

In the surveillance footage of a clothing store, the murderer was indeed found.

However, the murderer's vigilance is very high, he still covers his whole body tightly, but his white motorcycle helmet is very eye-catching, so we quickly judged that this is the murderer.

The killer had been hovering near the bank, and the time was shown to be 9:10 a.m. Twenty minutes before the explosion, the killer walked into the supermarket, bought a pack of cigarettes, and has been standing on the side of the road ever since.

However, the murderer was very cautious, he bought cigarettes, but he did not smoke because he was wearing a mask, and if he smoked, he would inevitably take off the mask. In order not to be seen by passers-by, he has not taken off his mask.

At 9:30, when the cash truck came to the bank, we could see that the murderer's hands were in his jacket pockets, and it could be seen that there must be a remote control device in his pockets.

Then there was an explosion, the surveillance footage shaking, the crowd scattered, and the smoke filled.

But we found that the killer was running towards the center of the explosion. But soon he turned and ran back. And fled the scene on the white motorcycle.

Obviously, the murderer wanted to take advantage of the chaos to snatch the cash box, but he found that the scene was not so easy to start, and the explosion was too powerful, causing great harm, and the murderer also panicked for a while, and finally had to flee in panic.

After that, Lao Lu retrieved a lot of surveillance and wanted to find the murderer's escape route, but the murderer was very cunning and deliberately avoided the monitoring, so that the police did not obtain the specific route of the murderer's escape.

However, in a large number of surveillance videos, we still identified some characteristics of the suspect.

First of all, the white scooter, a white scooter to be exact. This car does not have a license plate, but white battery cars are rare in urban areas, which can be used as a detection direction.

Then there is the height of the murderer, and I speculate that this person is about 165 centimeters tall and belongs to the short male stature. Although he was dressed very bloated, he still walked very lightly. So I judged that this person would not be more than 25 years old and had a thin body.

Finally, this person's walking posture is very distinctive, and he has the habit of stepping on tiptoes when walking, which may be related to his short stature, hoping to make himself appear less short by stepping on his toes. This idea is bizarre, but perhaps it is not too bizarre for a murderer who can plant and detonate a bomb.

The bombing case has attracted great attention from the whole city, and the public security department even issued a wanted warrant to the whole city through the public security WeChat platform, and posted screenshots of the murderer's video on the Internet, hoping that the general public can provide clues to find the bomber.

Brainstorming always has a great effect.

Sure enough, a citizen surnamed Liu reported to the police that the person on the video screenshot he knew and had repaired the air conditioner for his store.

I asked Mr. Liu, "Why are you so sure that the person on the screenshot of the video is someone you know?"

Mr. Liu said: "Because of the battery car and the white helmet. The master who came to repair the air conditioner also had the same battery car and helmet. ”

I asked again, "What is the age, height, and body shape of that air conditioner master?" ”

Mr. Liu said: "This air-conditioning master is about 1.65 meters, very young, only 23 or 4 years old, and his body is on the thin side. ”

I glanced at Lao Lu and said, "It's very close to the characteristics of the suspect I judged." ”

I continued: "Do you still have an impression of what this man looked like? ”

Mr. Liu said: "I have the impression that I have looked for him three times, and I still have his phone number. ”

Lao Lu hurriedly said, "How many phone calls?" ”

Mr. Liu took out his mobile phone and told us the number.

I said, "Mr. Liu, please call this number to give it a try, if it does, it will be said that the heating system of the air conditioner is broken, and let him repair it." ”

Mr. Liu hesitated for a moment and said, "Will I be retaliated against by this gangster?" ”

I frowned and thought for a moment, and said, "I'll dial." ”

So I took out my phone and dialed the number, and luckily, the call was dialed quickly.

'Toot ...... Honk...... Toot ......'

After a few clicks, the phone suddenly hung up.

The other party did not answer my call, but hung up on his own initiative. I called again, and the other party took the initiative to hang up again. When I called again, the other party had already turned off the phone.

Obviously, because of the explosion, the murderer is now very frightened, like a frightened bird, and he doesn't even dare to answer the phone call of strangers.

I asked Mr. Liu, "Do you know where this air conditioner master's shop is?" ”

Mr. Liu said, "Yes. ”

I said, "You describe the appearance of this air-conditioning master first, and then we will take us to this shop after making a portrait of the suspect." ”

Soon, according to Mr. Liu's description, the portrait of the suspect was drawn by the criminal portraitist of the criminal investigation team, and Mr. Liu said that the portrait was exactly the same as the air-conditioning master he had seen.
