Although Mr. Zhang is nearly seventy years old, he has his own unique observation angle and his own thoughts on the case and some news events.

The case was urgent, and I didn't stay at Mr. Zhang's house to accompany him to eat crabs and drink liquor, which made him a little unhappy and played a child's temper.

I had to promise that when the case was over, I would come back to visit him and have a drink with him.

He used to be a police officer, so he naturally knew the importance of the case, so he didn't force me to stay, and told me that if I didn't understand anything, I could come to him at any time.

When I left Mr. Zhang's house, it was already evening, and the sun was setting, exuding a warm light.

We currently have a lot of clues, and there are a lot of things that need to be done, and the case suddenly has so many directions for investigation, which makes me feel a little unaccustomed for a while.

After communicating with Mr. Zhang, I decided to talk to Meng Bochao, the bombmaker of the March 18 explosion, who was sentenced to life imprisonment seven years ago and should now be serving his sentence in a prison.

I returned to the office of the serious crime team, and everyone was still investigating according to the direction of the case investigation that had been formulated in advance, but the autopsy report of the forensic department had come out, and the two deceased killed in this case did die from the explosion, and Ren Qiushi found no other fatal injuries on their bodies.

At the same time, in the interrogation room of the criminal police team, Officer Wang is investigating and questioning the two survivors of the case.

More than an hour into the interview, the two survivors were still nervous, frightened, and even delirious to answer the police's questions accurately.

Officer Wang was not in a hurry, and tried his best to appease the emotions of the two, because this bombing case was very targeted, and it was aimed at their game production company. Therefore, the key to the investigation of this case should be from this game company.

The gaming company has just been around for three years and has only six employees. They simply rented a small studio in an office building in the central business district as the company's registered address.

Although the company has only been established for three years, and the game has only been released for more than two years, the games they produce and publish are particularly popular, and there are a considerable number of registered users of the game, which has also brought them a lot of benefits.

Therefore, it is not uncommon for this game production company to have enemies, and with their current achievements, they will definitely make other companies in the same industry blush.

I walked to the door of the interrogation room, and Officer Wang also saw me. After making eye contact with me, he immediately got up and left the interrogation room, handing over the investigation to his colleagues in the criminal police team.

"How? Any clues? Seeing him come out, I asked directly.

Officer Wang crossed his waist helplessly and made a somewhat hoarse voice: "Nothing." ”

After more than an hour of questioning, Officer Wang's mouth was already a little dry, but he did not ask any valuable clues.

Judging from the data, the six members of this game production company are not very old, they are all around 30 years old, and they are all a group of young people. Now there has been an explosion in the studio, and the company's colleagues have been killed, which has taken a big toll on their spirits.

"Nothing?" I frowned, very surprised by the result.

Officer Wang cleared his throat, nodded and said seriously: "At the time of the explosion, these two people went downstairs to get food, and as soon as they arrived downstairs, they heard a loud noise coming from upstairs. When they returned, they saw that their studio was in ruins, and in the studio, four colleagues were lying on the ground, so they hurriedly called the police and dialed 120. ”

I nodded, because it did match the situation at the time, and we did find a takeaway outside the door of the crime scene.

But as criminal policemen, the two of them are survivors, and there is still a theoretical possibility that after they planted the bomb, they left and detonated it by picking up takeaways.

"What about the company? And what about their social relationships? I made up my mind and asked.

Because this is a highly targeted bombing case, it is not only possible to be jealous of peers because of the company's achievements, but also because of their personal social relationships outside the country and being attacked by the murderer indiscriminately.

Sergeant Wang let out a long sigh and said very helplessly: "I didn't ask any useful clues, both of them said that there are no enemies outside the company, although there are competitors, but the categories of games we make are different and the audiences are different, so it is unlikely that we will have a feud." The social relationship between them did not ask any valuable clues, and they all said that a group of young people were programmers, and there were no enemies. ”

Programmer, in today's society, is no longer just a profession.

Behind this term, there is already a stereotype of this type of person.

When you think of programmers, you immediately think of a man, who is not very old, but has already lost his head, wears glasses, and looks very weak. They have an old-fashioned personality, but they are also well-behaved and honest, not good at socializing with people, and they will not make enemies outside.

"Has anyone in the company repaired the central air conditioner recently?" I made up my mind, and suddenly asked again.

The purpose of the criminals was to attack this studio, and the bomb was installed in the vent of their studio, very close. If the convict wants to plant a bomb, he will definitely go into this studio, open the vent from the studio, and install it.

If the bomb is installed for a long time, it is also necessary to connect to a power supply to ensure the power supply of the detonating mobile phone.

After hearing what I said, Officer Wang slapped his head and said with some remorse: "Oh, I was so confused by the two of them that I even forgot to ask such a crucial question." ”

After saying that, Officer Wang hurriedly turned around and walked into the interrogation room, and I followed him into the interrogation room.

"I don't know any enemies ......"

In the interrogation room, there were two pale, somewhat thin men. They were still carefully reminiscing, and gave the answer with certainty that there was no enemy.

"Have you repaired your air conditioner recently?" Officer Wang suddenly asked.

The two men were stunned, looked at each other, and shook their heads at the same frequency.

"Are you sure?" Officer Wang frowned and asked again.

"Officer, you're joking, we're just a small studio, how can we be qualified to repair air conditioners." A man replied weakly.

I was puzzled by his answer, and I took over and asked, "What do you mean by not being qualified to repair air conditioners?" ”

Another man smiled a little awkwardly and explained, "We needed to register a company because we needed to publish a game, so we rented a studio as the company's registered address. The studio was formerly the office of a large company, and half of the building was occupied by this company. Later, the big company moved away, and a few small companies came, the central control of the central air conditioning was in other rooms, and our studio only had a vent, which belonged to the rubbing air conditioner, so even if the air conditioner was broken, it was not our turn to find someone to repair. ”
