Bomberman Meng Bochao gave us a very positive answer, he made a total of 18 bombs in the serial bombing case seven years ago, and all 18 bombs were recorded by the police.

Meng Bochao did use a Motorola phone during the bomb he made seven years ago, and he did fill newspapers.

But he said the bombs were made eight years ago, in December.

If what he says is true, then the bomb in this case, which filled the February 16 of the following year, may not have been made by him.

I have already looked through the file of the bombing case seven years ago, and the so-called 18 March is only the date of the conclusion of the serial bombing case, and according to Mr. Zhang Fengtian's description, it took them more than a month to solve the case.

This shows that the entire series of bombings took more than a month from 18 March to the time they were solved. And the files clearly record the dates of the bombs and their dismantling.

It seems that all the clues indicate that the bomb has nothing to do with the bombing seven years ago.

But the file records that Meng Bochao was arrested on 19 February, three days from the date of the newspaper inside the bomb, and Meng Bochao had every time to make the bomb before he was arrested.

Was this bomb made by Meng Bochao?

If he made it, then who placed it?

Could it be that someone planted a bomb after he was imprisoned?

But by then, the police had confiscated and destroyed all the bombs......

All of a sudden, countless questions poured into my brain, and the case became confusing......

At the moment, the only thing that is certain is that the bomb was produced seven years ago, and as for other aspects, a big question mark will be drawn for the time being.

"Is it possible for a bomb from seven years ago to suddenly explode seven years later?" I froze and suddenly asked.

Meng Bochao thought for a while, cleared his throat, and said to me seriously: "It is very possible, as long as it is detonated. The device was not damaged and could be detonated at any time. ”

He was very sincere and very serious in his answers, and he seemed to be seriously discussing academic issues with me about bombs.

"Then if it detonates. Is it an old Motorola phone? I nodded and added.

After hearing this, Meng Bochao sat up straight, swallowed a mouthful of saliva vigorously, and explained to me very seriously: "Use your mobile phone as a detonation. The bomb of the device needs to make a call or send a text message to the mobile phone before it can be detonated. But if you want to leave it for seven years before detonating, you must ensure the quality of the phone, especially the power, so be sure to choose a place with a stable power supply as the place to put it. And the chip of the mobile phone must be modified so that the mobile phone only receives calls from fixed numbers, otherwise once someone makes the wrong call or receives a harassing call, it will immediately detonate the bomb. ”

After listening to Meng Bochao's narration, I once again fell into deep thought.

The killer planted the bomb seven years ago, but it didn't detonate it immediately at the time, and chose to detonate it seven years later, attacking a three-year-old studio.

Logically, it seems a little strange, how did the killer know in advance that the studio would be here four years later?

Thinking about it this way, there is only one conclusion, that is, the purpose of the murderer who planted the bomb seven years ago was the occupant of this studio seven years ago.

Then the question arises again, why didn't the murderer detonate the bomb immediately after planting it seven years ago? Now that the studio has changed people after seven years, why did the murderer detonate the bomb?

Could it be that this explosion was really an accident?

This bomb was not detonated by the murderer, but accidentally detonated because of an unexpected incident?

With a question, I asked again: "This kind of mobile phone as a detonation. Is there a possibility of accidental explosion of the bomb of the device? That is, on the premise of making a call from a fixed number, detonating by other methods? ”

Meng Bochao didn't care about the estrangement caused by the difference between himself being a criminal and I being a police officer, he was just seriously discussing one thing with me now, and the picture was like a junior asking a question from his senior.

Meng Bochao is a bomb maniac, and his knowledge of bombs is even more profound than that of Mr. Zhang Fengtian.

At the same time, he is especially willing to discuss bomb-related matters with others. After all, in prison, no one could talk to him about this topic, which made him feel a kind of kingly loneliness in his heart, which was a kind of loneliness of being alone and seeking defeat.

Meng Bochao said slowly: "If the bomb is unstable, it can also be detonated by external factors, such as heavy pressure and high temperature. ”

"What if it's a remote override detonation?" I added one more sentence.

Meng Bochao shook his head and said: "If it is detonated remotely, it is almost impossible, since the bomb has been made and the internal chip code has been written, it must be detonated by the designated number." ”

Hearing this, the case seems to have entered a dead end.

In seven years, will the murderer still detonate the bomb on the premise that he knows that detonating the bomb will not achieve his goal?

If it wasn't the bomb detonated by the murderer, then who was it?

The specified mobile phone number can be detonated......

At this time, I suddenly thought of an extremely fortuitous situation.

This kind of contingency may only exist in literary works, because it is really too accidental.

That is, after the card was cancelled and re-sold, seven years later it was in the hands of a completely unwitting person.

And this completely uninformed person, by mistake, dialed this phone number that can detonate the bomb......

Perhaps the occurrence of this bombing was a case that occurred by countless coincidences.

However, regardless of the nature of the case, this bombing case has already had serious consequences, and we, as policemen, must find out the matter when people's lives and property are damaged.

It is necessary to find out who made the bomb, who planted it, and who detonated it.

Through the conversation with Meng Bochao, we can temporarily rule out that this bomb is related to Meng Bochao, and then we will investigate from the company of this studio seven years ago.

Because the company seven years ago was the target of this bomb.

And it's a directional bomb, and the people who worked in this studio seven years ago are the core targets of this bomb.

"Hey, don't go, let's talk for a while!"

When Li Meng and I walked out of this room that made people feel a little depressed, Meng Bochao's somewhat lost cry came from behind him.

In seven years in prison, he hadn't talked to anyone about the bomb for a long time.

He had been looking forward to the day when someone who really knew and was interested in bombs would sit across from him, and the two would have a good conversation.

Because he's a bomb maniac, an absolute professional in the field of explosives.

If he can apply these skills to the right path, he will definitely be a person with extraordinary achievements.

"Hey! If there's anything you want to know, remember to come to me! ”

We had already walked some distance, and once again there was a cry of desperation from behind.

I didn't say goodbye to him.

Because I'm a police officer, he's a criminal.
