Jinpei Matsuda and Miwako Sato returned to the Search Division.
Miwako Sato is analyzing the confession of the flower shop owner:
"Miss Yun Gu said that she heard some strange noises from her neighbor's house around seven o'clock in the evening. However, the victim, Shikaya Kinko, had a habit of drinking and would always make some noise when she was drunk. Therefore, Miss Yun Gu did not care."
"The victim Kabutani Kinko said that her room was turned into a mess and she hid a large amount of money in the middle of her coat. Now the money is missing."
Matsuda Jinpei looked at Shikaya Kinko's information.
Shikaya Kinko used to be a nurse at Rice Flower Hospital. After her parents died in a car accident, she was devastated. She was fired from the hospital due to work mistakes. After that, she began to drink and drink.
Fortunately, her deceased parents left her a modest inheritance, which could support her for a period of time. But now, that inheritance has almost been spent, so Shikaya Kinko's life is now stretched.
He is also a poor person, Matsuda Jinpei thought.
But pity doesn't mean harmless.
"Matsuda, Matsuda!"
Miwako Sato's call interrupted Matsuda Jinpei's contemplation. The short-haired policewoman was looking at him with some dissatisfaction, as if scolding him for being distracted.
In order to prove that he was not distracted, Matsuda Jinpei expressed his speculation: "I think there is a problem with this case, but the problem is not the testimony of Mina Kumotani, but the testimony of Kinko Shikaya."
"First of all, when a thief enters a house, will he really dig through all the places?" Matsuda pointed to the photos of a messy scene. "Similarly, when a thief is looking for money, will he focus on the wardrobe?"
Miwako also understood what Matsuda Jinpei meant, and she had actually thought about this issue.
Because according to Shikaya Kinko's explanation, this was very much like a false alarm.
"Matsuda." Sato suddenly stared at his juniors very seriously, "No matter what, we must not think like this."
"Is there clear evidence now that the victim was making a false alarm? No. So we must investigate carefully to the best of our ability. If not, it will set a very bad precedent.
"We are not detectives, but police. Jumping to conclusions without clear evidence will distort our style. It is very likely that in the end, the police will try to save trouble and hastily close the case when the evidence is insufficient or even wrong."
"That's what Officer Sato said."
This time, Matsuda Jinpei answered very seriously. He thought of some past events.
As a thorn who joins the police academy with the goal of beating up the police chief; Matsuda Jinpei has been unruly since he entered the police academy until now.
Therefore, Miwako, who had just met Matsuda Jinpei, didn't know how rare this seriousness was, just like a wolf that had always shown its fangs and suddenly lowered its eyebrows like a dog.
"According to this situation, we still need to go and see the scene." Officer Sato said.
Matsuda was about to nod. The office door was pushed open by another person.
It's Mu Mu Thirteen.
"Matsuda, Search Section 4 needs your help." Officer Megure wiped the sweat from his forehead. It could be seen that he was quite busy.
Search over there in Section 4? As far as Matsuda Jinpei knows, he is specifically responsible for group violence cases. No explosive ordnance disposal squad was dispatched, so there should be no bombs. It might be a case involving explosives.
"Search Section 4? Matsuda, you go first." Sato Miwako said, "I will go to the scene myself."
"good."
----------------------------------------
Only one person came to search Section 4.
He is a young man, very tall, with slightly long hair and bangs covering his eyes. He stood leaning against the wall, scrolling through his phone.
The fluorescent light from his cell phone made his face look a bit eerie.
"Let me introduce myself, I am Qian Mu Liangchen from the Fourth Investigation Department." The man put away his mobile phone and said.
"Officer Qian Muliang." Matsuda Jinpei nodded.
Although he needed his help, this colleague's attitude was very cold and somewhat probing: "The Yantian Police Department recommended you to me - are you familiar with all kinds of bombs?"
"That's right."
Matsuda Jinpei raised his eyebrows. No one had ever questioned his bomb disposal ability.
"OK."
The two went upstairs and walked to the office area where Section 4 was searched. Qian Muliang led Matsuda Jinpei through the bright and spacious office area and stopped at the end of the corridor.
"This is the utility room."
"You have good eyesight, Officer Matsuda." Qian Muliang said.
This utility room has been converted into his office by Qian Muliang. As soon as Matsuda Jinpei entered the door, he was shocked by the full wall:
A large notice board is attached to the wall. The notice board is filled with photos and reports on nails of different colors, with dates marked next to it. Handwriting of different colors connects the photos together, and occasionally a question mark or triangle symbol is drawn.
The earliest dates for those reports were twelve years ago.
"Those are……"
"You don't have to worry about it."
Matsuda Jinpei: "Although you need my help, I always feel that Officer Senki Ryo doesn't welcome me."
Qian Muliang bent down, took out a small bottle and a stack of photos from the office cabinet, and placed them on his desk.
"Then..." The tall police officer glanced at him, "You don't have to worry about it?"
Matsuda Jinpei was at a rare loss for words. He couldn't tell whether the other party was unsociable or simply in need of a beating.
When he was in the police academy, he might have had a discussion with the other party about this issue, and he would have started fighting with someone like Jiang Guling.
But after working, Matsuda Jinpei became much calmer. Moreover, since Hagiwara left, he has lost the desire to care about many things.
"Based on these photos, can you analyze what kind of bomb it was?"
"Let me take a look." Matsuda Jinpei picked up the photos and looked through two of them. "Based on the intensity and range of the explosion, it might be PENT or TNT. I see that you also collected soil from the site?"
"That's right."
Matsuda turned the small glass bottle on the table: "It's sealed well. I need to measure the pH of the soil."
"PH?" Qian Muliang frowned, "Sorry, officer, I may not have special equipment here."
"It's okay. I have it here. You can get it now."
Matsuda Jinpei returned to the search class. He took out a small white box from the drawer of his desk and brought a bottle of pure water.
"Just use a pH meter."
Back in Qian Muliang's office, Matsuda opened the small box and took out a small measuring cup and an instruction manual.
"Dilute according to the ratio on the instruction manual." Matsuda Jinpei instructed the police officer who searched Section 4, "Use purified water, and you control the dosage."
Qian Muliang took the purified water from Matsuda Jinpei. He was a little curious as to why Matsuda Jinpei had left the explosive ordnance disposal class and was still carrying these professional equipment.
The instructions are slightly yellowed and appear to have been aged.
Qian Muliang turned his attention to the small box that packaged the pH tester. On that box, a surname was marked with a gel pen:
Hagiwara.
