Hearing that Lin Xinyi didn't find any clues, Officer Sakata didn't show any disappointment.

He just naturally helped analyze the case: "If there are no clues here, it seems that we can only wait for the results of the investigation of the driver's license by the government police headquarters to find out the true face of the murderer." ”

"Yes, the focus is still on investigating the social connections of the three victims."

Lin Xinyi casually agreed, and then turned his head to look at the corpse again.

He didn't explain much, just buried his head and continued to carefully examine the body of the deceased.

Officer Sakata's expression quietly became subtle:

"Steward Lin, is the autopsy going to continue?"

"Well, it's not done yet."

Lin Xinyi replied calmly:

"Every corner of the deceased's body must be examined according to the procedure, otherwise there may be omissions."

"Sometimes some seemingly insignificant traces can become the key clues to solve the case."

"That's right..."

"Officer Lin's work attitude is really rigorous."

Seeing that Lin Xinyi was not tired of being disgusting and tedious, and carefully examined the corpse's attentive appearance, Yusuke Sakata couldn't help but sigh politely.

Subsequently, he, like Hattori Heiji and others, waited earnestly for Lin Xinyi's further autopsy results on the side.

After a long time...

Lin Xinyi examined the deceased's ankle.

He seemed to have found some important clue, and his gaze quietly became solemn.

"Supervisor Lin, what's wrong?"

Yusuke Sakata asked actively.

"......" Lin Xin was silent for a while.

He pondered for a while, and then he did not shy away from saying what he had discovered:

"The ankle of the deceased's right leg, which is on the heel, has a small area of epidermal peeling."

"The fact that there is this level of exfoliation of the epidermis without accompanying life reactions such as bleeding suggests that the injury was formed after the victim's death."

And, you can also imagine:"

"Places like the heels don't have much chance to rub against hard objects under normal circumstances, so such skin damage rarely occurs."

"So..."

Lin Xinyi guided the way and talked about the injury to the deceased's ankle.

Miss Maolilan, who had been serving as his assistant, quickly reacted and completed the answer:

"So this is the injury caused by the murderer's heels dragging on the ground and rubbing against the ground when the murderer carried the body after killing the deceased?"

She gave a conjecture and then explained:

"Because the deceased was extremely strong, even if the murderer was strong, he might not be able to carry him."

"So the murderer will choose to use the 'drag' position, so that the body is facing away from him, holding the deceased's armpits with both hands, and dragging the body backwards."

"And if you use this position, the heel of the deceased will always rub against the ground."

Saying that, Mao Lilan also deliberately put down the figure of the Kanto karate champion, and imitated the appearance of those "weak" ordinary people, simulating an action of dragging the corpse with great effort.

"It's very likely."

"But the injury to the deceased's ankle should not have been rubbed on the ground."

"It's hard to wear through the skin on a smooth floor, and if it's rubbed against the rough concrete floor outside, a lot of dust will get involved in the wound."

"But the deceased's ankle wounds and socks on his ankles looked relatively clean and free of dust."

"And..."

Lin Xinyi leaned over and squatted down, signaling everyone to follow closely and observe:

"If you look closely, you can see that the wound on the deceased's ankle and the socks at the wound have a little black paint spot and reddish-brown rust."

"This indicates that the heel of the deceased had rubbed against some kind of metal part that was painted black and slightly rusted."

"What do you think this metal part would be?"

"This..."Everyone looked at each other:

Metal parts painted with black paint are quite common in life.

But if you want to find a metal part that is most likely to be touched by the heel of the corpse in the process of carrying the body after the death of the deceased... That's a test of the imagination.

"What is it that scrapes against the heel of a corpse?"

"Could it be..."

Hattori's pupils shrank, as if he had thought of something.

He used his imagination as a detective to join the discussion:

"It's the lock in the trunk of a car, right?"

"The trunk locks of old-fashioned cars are made of metal, and the anti-rust treatment is not done well, so it is easy to peel off paint and rust."

"And the edge of the metal lock is relatively sharp, and it is indeed easy to scratch the skin when rubbed."

"What's more..."

Hattori Heiji said with sharp eyes:

"The deceased was most likely killed by the murderer elsewhere and then transported to this building to dump his body."

"And this is a downtown area, even in the middle of the night when no one is around, the murderer can't be bold enough to drag a corpse on the road."

"So, he must have put the body in the trunk first, and then drove it to the alley where the back door of this building was heading."

"And as the killer opened the lid and dragged the body out of the trunk..."

He paused slightly, and almost definitively came to the conclusion:

"The heel of the corpse is easily scratched by the metal lock of the trunk!"

"In this way, the strange phenomenon of paint spots and rust on the wound on the deceased's ankle can be reasonably explained."

"I see—" Maolilan nodded in realization.

She has unconsciously invested in the reasoning and eyes of the case.

Therefore, ignoring the resentful gaze of a certain imp and a certain girl beside him, Mao Lilan unconsciously became Hattori Heiji's reasoning partner:

"This is a very important clue!"

"It's hard to notice a place like a car trunk lock."

"No matter how strong the murderer's anti-reconnaissance consciousness is, it is estimated that he will not notice that in the process of carrying the corpse, the heel of the corpse will be scratched on the metal lock."

"So...", Maolilan's eyes lit up with excitement:

"It's likely that the killer didn't take care of the marks on the car's metal lock at all."

"In the trunk lock of that car, you should be able to find the dander left by the deceased—"

"And this is conclusive evidence that is enough to convict the murderer!"

As soon as these words came out, the facts of the case suddenly became clearer.

"That's right." Lin Xinyi nodded appreciatively:

"As I said before, the more scheming people are, the easier it is to get into unexpected situations."

"It's hard for him to notice something as inconspicuous as a trunk lock."

Hearing this, Officer Sakata's expression on the side couldn't help but become a little complicated:

"yes, yes, if that's the case..."

"Then we only need to confirm the identity of the murderer and find the car in which he transported the body, and then we can arrest him!"

He echoed and said a few words, and his expression quickly regained his composure.

Not only that, Officer Sakata also praised with emotion:

"Worthy of being the forest management officer of the Metropolitan Police Department..."

"So quickly identified the key direction for us to find evidence!"

"Haha."

Lin Xinyi smiled naturally:

"I've only done very limited work."

"Next, we have to rely on the strength of the Osaka Prefectural Police."

"Only by finding clues from the victim's driver's license as soon as possible and finding a way to confirm the identity of the murderer, can these discoveries of mine come in handy!"

As he spoke, he made a businesslike appearance and said to Officer Sakata:

"Officer Sakata, now that this is happening, I can't eat."

"I won't bother you to entertain us again."

"When the police arrive at the scene, we will follow them back to the Osaka Prefectural Police Headquarters ourselves."

"So, if you have any other work, go ahead and get busy!"

"Hmm...," Officer Sakata thought for a moment.

He quickly agreed to Lin Xinyi's proposal:

"Yes, the next thing is the work of you and the prefectural police headquarters, and I can't help much."

"Administrator Nabayashi, I'll go back to the Tojiri Police Station first."

"The police car I was driving was smashed like this by a corpse, and I really have to go back and report it to the department."

"Okay, goodbye."

Lin Xinyi smiled and said goodbye to Officer Sakata.

Officer Sakata also nodded slightly, and then said goodbye to everyone and left the scene alone.

And as soon as he left...

Lin Xinyi suddenly turned around and said to Hattori Heiji:

"Mr. Hattori."

"You can call your dad."

"Huh?" Hattori Heiji was slightly stunned: "What, what do you mean?" ”

"I have a suspicious target."

Lin Xinyi replied unhurriedly:

"Next, it's time to verify the answer."

..............................

Half an hour later, the Higashiri branch office, underground garage.

Parking here are all private cars used by police officers to commute to and from work.

It was the police station's working hours, and no one would use their personal vehicles, so the underground garage was empty and extremely quiet.

A figure quietly stepped out of the elevator and into the garage.

It was Officer Yusuke Sakata, who had said goodbye to Lin Shinichi and others and returned to work alone at the Tojiri Branch.

With a small plastic bag in his hand, he hurried out of the elevator and found the place where he parked.

It was an old Toyota, and it looked like it was some years old.

Yusuke Sakata took out the key and opened the trunk.

The latch of the trunk opened, and there was a metallic crunch with a click.

Yusuke Sakata lifted the lid of the trunk, and then opened the plastic bag he was carrying, and took out a stack of paper towels and a bottle from it.

There is packaging on the bottle.

The package reads: "Bleach".

Yusuke Sakata hurriedly wants to unscrew the cap, and at this moment...

The originally quiet underground garage was uninhabited, but suddenly there was a wave of footsteps.

Dozens of police officers appeared from all directions like divine soldiers, all with guns in their hands.

Using the cars and pillars in the garage as cover, they quickly approached the center and surrounded Yusuke Sakata.

And standing in front of those police officers is Lin Xinyi.

He was accompanied by the head of the Osaka Prefectural Police Headquarters, Hattori Heiji's father, who rarely goes out in person, and the police inspector Hattori Heizou.

"This, this..."

Yusuke Sakata was stunned.

He stood there dumbfounded, the bottle of bleach in his hand, his face as pale as paper.

"Yusuke Sakata..."

Hattori Heizou always has an aura of a superior who is not angry and arrogant.

And at this time, in the face of Yusuke Sakata, there was an unconcealed anger in that majesty:

"Are you worthy of the police badge you carry?!"

"I..."Yusuke Sakata was speechless for a moment.

He hadn't reacted to the shocking scene at all.

And Lin Xinyi looked at the bleach in his hand, as well as the trunk that was opened in front of him, and couldn't help but say in a relaxed tone:

"Officer Sakata..."

"Thank you for helping us find all the evidence."
