Conan Super Detective

· Under Watson's suspicious gaze, Dong Ma knelt down and picked up a piece of browned paper that looked like a news newspaper and a fragment like a test tube.-V

"This should be the wrapping paper used to fill the fuel and the gaps in the ancient wind cover on the earthen-made iron pipe bombs. The reason why it can still be seen now is because it will be accompanied by the storm from the pipe before the explosion burns it out. Spray out..."

Dongma shook the broken pipe in his hand.

"Of course, the current military bombs use pulp instead of old newspapers."

Dongma added.

"Yes, Master Dongma, the bomb disposal team also said the same."

Miwako, who doesn't know when he will come back, echoes the Tao.

"We are now investigating the recent commercial theft to see if there is any loss of flammable chemicals and gunpowder..."

"Ok……"

Dongma nodded again, and then looked at a motherboard on the ground.

"Master Dongma, this is an Internet company. It's no surprise to find a computer motherboard, right?"

Bella couldn't help but reminded.

"But this is not the computer motherboard, but the pager's motherboard."

Dongma picked up the motherboard about half the size of a palm and showed it to everyone.

"There is a receiver on the motherboard but no transmitter, so the question arises. Why does such a modern Internet company have a pager that has long been obsolete by the times?"

"You mean, it might have something to do with the bomb?!"

Bella reacted immediately.

"To be precise, this should be the detonating device. Depending on the degree of damage to the motherboard, I think I will be able to use this device to track down the owner soon."

Sure enough, after two hours, Dongma got the test result given by Xiuzi.

"This pager is indeed the detonating device of the bomb. Because it is prepaid, there is no user information. Fortunately, I retrieved the pager number, and there happened to be a number that I called this number three times this morning and it exploded. A few seconds before it happened."

Xiuzi said confidently.

"Have you tracked down the owner of that number?"

Dongma asked with a smile.

"Yes, Fushiji Haneda, the repairman in Chiyoda Ward, was sentenced to four years in prison for burning his home and defrauding insurance money. He was not released until a week ago."

Miwako added.

"The motive for committing the crime?"

Dongma continued to ask.

"It's not clear yet. I think if you interrogate him yourself, you should get the result soon."

Miwako is very confident in Dongma's psychological knowledge.

...

Later, Dong Ma saw this man in the interrogation room of the Metropolitan Police Department.

Obviously freshly dyed white hair, a half-zipped jacket, and a watch with a crack in the glass.

Dongma looked at the clock on the wall subconsciously and found that his watch was seven minutes slow.

"I told you! I just wanted to hand in a takeaway this morning! But I dialed the wrong number!"

Haneda emphasized loudly.

"Indeed, the delivery phone number of the pizza restaurant next door to you is indeed very similar to this number, with only one number missing, but it is not enough to let us leave you."

At this time when Haneda might be a terrorist, Bella naturally couldn't let him leave because of this.

"What do you think?"

Through the one-way glass, Watson asked in a low voice.

"Bomb monsters are usually people who pay attention to details, but look at his dress and the obviously slower watch. It's really not like someone who risked his life to make bombs and blow up buildings."

Dongma shook his head.

"However, a bomber in the U.S. who was active in the 1970s to the 1990s, dressed like a tramp."

Watson retorted.

"It makes sense... then let's see what's going on at the bomb disposal team."

Dongma nodded, then got up and left the interrogation room.

The 2830th chapter echoes the explosion on the timeline (two)

"How is the analysis?"

The person in charge of the bomb disposal team briefing was a forty-year-old bald head, who was facing a pile of seemingly unconnected fragments, preparing for the next explanation.

"It's basically over, you can start the briefing."

Bald head nodded and replied.

"Before that, can I ask a few questions?"

Dongma glanced at the bomb parts arranged on the long table.

"Excuse me, answering your questions is also part of our work."

Bald said respectfully and confidently.

It seems to him that even well-known police detectives across the country should ask him for advice on the bomb.

"I think this is the power source for the bomb?"

Dongma asked, pointing to a battery marked with mountains and sun.

"Yes, Fuji Electric, established at the beginning of the last century, is the final version of their last generation of commercial batteries."

Bald head replied affirmatively.

"But if I remember correctly, this brand's trademark has a pine and cypress tree added two years ago to celebrate the company's centennial birthday."
