Jiang Tingbai found newspaper debris at the scene of the crime, and all of us agreed that these newspapers should have appeared as man-made bomb fillers, and under the impact of a huge explosion, the newspapers were shattered and formed into debris.

In today's era, newspapers are definitely a "rarity", so the murderer of the bomb must be a person who has access to newspapers.

There are now very few retail outlets selling newspapers, and even the kiosks that used to exist at every intersection in Ningzhou have long since been demolished.

Nowadays, the only way to buy a newspaper is through a subscription.

The murderer used newspaper as the bomb filler, but the bomb was not necessarily filled with newspaper, other papers, and even toilet paper were fine.

Because of this, newspapers must be the most common item around the murderer.

It is highly likely that the murderer worked in the place where the newspaper was printed and where it was sold.

This has been of great help to us in locking down the identity and direction of the murderer.

The technical team did not collect valuable fingerprints and footprints at the site, because everything was covered in ashes.

After all, this is an explosion, and the collection of explosives fragments is the most important thing.

The technical team collected a large number of pieces similar to motherboards at the scene, these pieces have no outer packaging, and the green motherboard and the lines on it remind me of the Nintendo game console I played when I was a child.

I don't know the specific use of these things, but in the Technical Investigation Department of the Ningzhou Public Security Bureau, there is an expert.

But then again, it's a game production company full of electronics, and it's not surprising that this kind of motherboard fragmentation appears after the Big Bang.

With pieces of motherboard pieces packed into the evidence bag, the preliminary on-site investigation was over.

Unfortunately, apart from newspaper debris, we found no other fragments of what could be a man-made bomb.

Next, the technical team needs to conduct a second survey of the site, focusing on the collection of fingerprints and footprints that may be found at the scene, as well as biological samples, as well as the inspection of the ventilation ducts where the man-made bombs are stored.

These are very time-consuming, and there is no way to get results in a short period of time.

Therefore, the serious crime team and the criminal police team returned to the Ningzhou City Public Security Bureau with the physical evidence collected so far to investigate the explosion case.

Lin Zifan and Xue Hang went to investigate the printing and sales of the newspaper to see if they could find any clues. Jiang Tingbai continued to go to the trace examination department to be busy, and Li Meng needed to find out which newspaper issued this newspaper through the fragments and texts on the newspaper, and even what day it was issued.

I reported the details of this explosion case to Shen Ruoshan, the head of the serious crime team, and Shen Ruoshan expressed great satisfaction with our behavior that as adult criminal policemen, we can take over the case and solve it by ourselves, and also praised us for accurately judging the direction of the investigation of the case through the situation at the scene of the crime, and there are no shortcomings of young criminal policemen.

In the end, Shen Ruoshan gave me the contact information of Mr. Zhang Fengtian, a "bomb disposal expert", and said that I could consult him if I had any difficulties.

After hanging up the phone, I trotted into the office of the Technical Investigation Bureau with more than 50 bags of evidence on both ends.

"Holy! Who is it! ”

I didn't knock on the door and pushed the door directly in, which scared Xiao Xuan suddenly.

Sure enough, he was fishing and fighting the landlord at work again.

"I can understand what kind of e-sports game you play, what's so fun about fighting landlords?" I threw more than fifty bags of evidence on his desk and said helplessly.

"Brother Qin, you don't understand this, fighting the landlord is a game that requires a lot of brains, although there are only seventeen cards per person, but, what are the remaining cards, who are in whose hands, how many probabilities there are, and what is the probability of each probability, all need to be calculated." Xiao Xuan sat on the chair and said to me while operating the mobile phone to play cards.

I looked at his serious appearance and couldn't help laughing: "Alas, a good hacker, addicted to fighting landlords, there is really no one." ”

"Who said hackers can't fight landlords?" Xiao Xuan suddenly asked me.

I walked up to him, glanced at his game interface, and said in a weird way: "Hackers can fight landlords, but why do hackers keep losing when fighting landlords?" You're so good at calculating, why don't you keep winning? ”

It is said that scolding does not expose shortcomings, but I prefer to expose Xiaoxuan's shortcomings, because he can come here because he stole happy beans through the implantation of Trojan horses through network vulnerabilities, hahaha.

Every time I think about it, I can't help but laugh.

"Brother Qin, do you understand? In any game, there is an element of luck! You've played Minesweeper, right? No matter how you calculate, at the end of the calculation, when there are two blank spaces left, you can only rely on luck. For there are two left, and one must be thunder and one space. Xiao Xuan explained to me seriously.

As soon as his voice fell, there was a unique sound effect on his mobile phone that the landlord had lost.

"Hahaha, it seems that our great hacker Xiao Xuan is not very lucky today!"

I don't know why, but when I heard the sound on his phone, I couldn't help but want to laugh at him.

Xiao Xuan gave me a fierce look, threw the phone on the table, and said angrily: "Brother Qin, you are really my nemesis, I kept winning before you came, you know?" Are you really unlucky!! ”

I smiled and didn't continue, after all, I had come to ask him for help this time.

I walked up to him, leaned back against the desk and looked at him, and said seriously, "Jokes are jokes, I'm here to ask you for help this time." ”

With that, I pushed the more than fifty bags of evidence on the table in front of him.

Xiao Xuan frowned suddenly, looked at me with some surprise, and said with panic in his eyes: "Brother Qin, you won't let me repair these motherboards, right?!" ”

Seeing that he was a little scared, I quickly explained: "It's not for you to repair, it's for you to carefully identify, where these motherboards came from and what they do." These are all from the scene of the crime, and a lot of them are fragments, and it would be better if you could put them back together. ”

After Xiao Xuan heard that there was no need to repair it, his mood eased significantly, but after he saw such a large number of motherboards on the table, he still swallowed hard and said, "This ...... That's a big project. ”

"Oops, it's a big project for others, but isn't it a piece of cake for our great hacker Xiao Xuan?" I patted him on the shoulder and began to sugarcoat the cannonball.

Although Xiao Xuan is about the same age as me, only a few years younger than me, I have always treated him as a child.

Moreover, his personality is also like that of a child.

Seeing that there was still some resistance in his heart, I immediately added: "These are all physical evidence, very important clues, you must identify them as soon as possible, the serious crime team is still waiting to rely on these to solve the case!" ”

I took things up to the next level, and after Xiao Xuan listened, he immediately settled down and began to identify these motherboard fragments.

For us, these motherboards all look the same, but for Xiao Xuan, he can judge the purpose of this motherboard from the direction of the lines on each motherboard.

He opened the evidence bags one by one and began to make them carefully......
