Chapter 481 The Reason Why I Can’t Tell You (Please Vote and Subscribe!!!)

"Mr. Koizumi, what was the reason for your quarrel with Ota Kunimatsu?"

After the fire, in the ruined gymnasium, Megure Thirteen changed the subject and questioned Koizumi Ryuji.

Koizumi Ryuji previously said that he had nothing to do with Ota Kunimatsu, but

If there is nothing wrong with you, why would you have a dispute with the other party?

It is conceivable that a person suffering from social phobia can be extremely conflicted.

Even the old principal was a little surprised:

"Ryuji, you actually had a quarrel with Mr. Ota?"

"Teacher Uematsu, I, I."

The palms of his hands began to tremble, and Koizumi Ryuji was speechless for a while.

He seemed to be hiding something.

"Mr. Koizumi, if you don't tell the truth, we will have to take you back to the police station for investigation."

Mumu Shisan said seriously:

"If you are not a criminal, it is better to explain the reason as soon as possible."

"I, I, am really not a criminal."

While hemming and hawing, Koizumi Ryuji still refused to tell the reason for the quarrel.

This made Sakaki a little curious.

The reason why he would rather be taken to the police station as a criminal than to speak out, what exactly is involved?

What's more

"Mu Mu Police Department, the investigation is not over yet and there are insufficient evidence and clues."

He stopped Takagi Wataru from moving forward to escort Koizumi Ryuji and said:

"Even if Ryuji Koizumi is brought back to the police station now, it will only be harmful to the case."

The motive and means of committing the crime are unclear, and no evidence has been found.

Just because Koizumi Ryuji refused to tell the reason for the dispute with the deceased, he regarded the other party as a prisoner, no matter from which perspective

None of them are suitable.

"Right!"

The secretary added:

"Samejima-sensei, the gardener, also had a quarrel with Ohta-sensei!"

Everyone: "."

Why didn't you say something so important earlier? !

With a wave of his hand, Megure Thirteen asked Takagi Wataru to let go of Koizumi Ryuuji, and then asked:

"Mr. Samejima, what was the reason for your dispute with the deceased?"

"It's not like you can't say it, right?"

"Oh"

Samejima Toshio smiled coldly, looked around, and his eyes rested on Somohei's body for a breath:

"There was an infestation in the flowerbed almost a month ago."

"For medicine, I asked Ota Kunimatsu to buy imidacloprid, and the result"

"He promised verbally, but then forgot about it. He delayed it again and again, causing heavy losses to the flowers and plants!"

Sakaki has heard of imidacloprid, which is a neonicotinoid compound and a systemic insecticide that can interfere with the transmission of stimuli in the nervous system of insects, causing paralysis and death of insects.

It is very versatile and famous.

Such a thing as insect infestation

It doesn’t matter if it’s big or small, it doesn’t mean it’s small.

If they cannot be stopped in time, when they multiply, like locusts, the disaster they cause will be devastating.

It is understandable that Samejima Toshio would hold a grudge against Ota Kunimatsu.

"Teacher Samejima, such a thing has happened. Alas!"

The old principal sighed:

"Why don't you tell me?"

"snort!"

Staring at him unceremoniously, Samejima Toshio said angrily:

"It was only a few days ago that I found out that he didn't buy the medicine. It was too late to report!"

"Get out of the way!"

"I want to spray the flowerbed!"

He pushed away the police around him and walked forcefully out of the stadium.

Mumu Shisan winked, and Gao Mushe understood it and immediately followed to prevent the other party from destroying evidence or escaping.

"Sorry, Mr. Police Department"

The old principal bowed slightly:

"Samejima-sensei has a withdrawn personality and values ​​the garden more than his life."

"If anyone touches his precious flower garden, he will definitely not let it go."

Mu Mu Thirteen: "."

broken

he thought.

Whether it’s Toshio Samejima, the gardener, or Ryuji Koizumi, the cleaner.

They all have motives for committing crimes!

The only one who seems to be relatively innocent is Risa Goto.

"Principal Uematsu, how many years has Ota Kunimatsu been a health teacher at the school?"

"It must have been almost 12 years."

The old principal raised his head slightly, showing a thoughtful look:

"I remember"

"When Ohta-sensei joined the company, it happened to be the year Sakaki Makoto-kun graduated."

The year you graduated?

Hattori Heiji was stunned for a moment, looked at the back in front of him, and discovered.

Like him, Sakaki narrowed his eyes, seeming to notice something was wrong.

Sakaki is 23 years old and graduated from Tedan Elementary School.

There are six grades in Didan Primary School. The year he graduated, he should have just entered the sixth grade.

Ryuji Koizumi is 22 years old, exactly one year younger than him, and was in fifth grade at the time.

5th grade

Isn't this the exact time when Ryuji Koizumi was bullied at school?

school bullying

Is it related to Ota Kunimatsu?

No no no.

Shaking his head, Sakaki gave up the idea.

Since Principal Uematsu knows about the campus bullying incident, it means that he knows the inside story.

If Ota Kunimatsu was involved in school bullying, would he still be a health teacher at Tedan Elementary School?

He believes that the principal of a school will not condone bullying incidents.

"Report!"

A firm voice interrupted Sakaki's thoughts.

A firefighter from the Fire Investigation Department came over with the record and said loudly:

"After careful investigation, we have just determined that the location of the fire was the warehouse under the podium!"

"At the same time, we also found traces of burning gasoline on the ground!"

Fire Investigation Division, a mysterious profession.

To ordinary people, the fire scene is pitch black, but to the Fire Investigation Bureau personnel, it is filled with countless clues.

They study fire day in and day out, with tools in hand and a wealth of experience.

For example, there is a depth measuring instrument that can measure the thickness of the charcoal layer after burning wooden furniture to determine the approximate duration of the accident and the location of the fire.

Where gasoline has burned, it will also leave different marks.

When it comes to fire scenes, even forensics classes can't compete with them.

This is also the reason why Mumu Thirteen did not send out a forensics class.

At this point, the duties of the fire brigade ended and the case was completely transferred to the Metropolitan Police Department.

The fire occurred in a warehouse and the cause of the fire was gasoline.

All signs indicate that Sakaki's reasoning is correct.

this.

Undoubtedly a murder!

But Mu Mu Thirteen now has two heads on one head.

Even if the fire brigade provides them with information, the case still cannot be solved!

There is no evidence, and there are not enough clues.

Is it really going to be an unsolved case?

Sakaki also had a headache.

The prisoner obviously planned carefully. He eliminated most of the traces with a fire. The fragments he obtained were very limited and were not enough to use profiling.

Crack!

Lighting a cigarette, Sakaki gradually calmed down.

What's the use of being anxious?

It won't help the case in any way.

Smoke curled up and drifted upward.

He stared at the smoke, slowly raised his head, and his pupils suddenly shrank!

"Principal Uematsu!"

In full view of everyone, Sakaki shouted:

“Where is the distribution box for the stadium located?”
