"The side of the glass facing the inside of the house has less dust."

"The side facing the outside has more dust."

"Through this, we can simply judge which side of the broken glass on the ground is facing inward and which is facing outward."

Mao Lilan perfectly applied the knowledge taught by Lin Xinyi to practice:

"Then, we spliced ​​the glass fragments together and conducted an overall inspection, and determined the point where the glass was first subjected to force and the radiation cracks formed."

"Then change the irradiation angle of the light and observe the radiation crack section."

"We found 'single-knife-like' arcuate lines on the fracture surface."

"And the converging directions are all towards the side with less dust, that is, the side towards the inside of the house."

According to the principle of breaking glass under the action of mechanical load, after being broken by force, the broken section of glass will form bow-shaped lines visible to the naked eye.

These bow-shaped lines actually reflect the mechanical waveform of the force spreading on the glass.

Therefore, extend the converging direction of the bow-shaped lines, and the point where they converge is the specific force-bearing point.

Now, this specific point of force is on the side of the glass facing the inside of the room.

"So, we can determine that:"

"When the glass is broken by an external force for the first time, the force should be on the inner side of the glass."

"With the doors and windows of the villa closed, this glass door..."

"It should be that the murderer acted on the glass from the inside to the outside of the house to make it shatter."

"This proves that this 'robbery and murder scene that broke into the house from outside' was forged by the murderer!"

"This is an acquaintance committing the crime, forging the scene of murder and robbery."

Mao Lilan's eyes shone with confidence, and she spoke her own conclusion.

"Very well, Miss Maury, you are doing well."

Lin Xinyi was very pleased to express his praise:

The strange footprints on the lawn, the damage form of the deceased who suffered excessive violence, and the real evidence that Mao Lilan found from the glass door using scientific analysis methods.

The combination of these clues and evidence can already characterize the case as an acquaintance.

"Not only that..." Mao Lilan continued:

"During the investigation, our on-site inspection team did not find any photos left by the head of the household in the villa, but found two bedrooms with obvious traces of life—"

"There are obviously two people living in this villa, and judging from the clothes in the bedroom, they are all grown men."

"A business card was found in one of the rooms. The owner of the business card is an executive of a securities company, Mr. Tomoshi Tanaka."

"As for the manuscript found in another room, the signature on it is 'Tanaka Kazuyuki'."

"The two of them should be related."

"And the deceased may be one of them."

The deceased was one of the two residents of the villa, and this case was committed by an acquaintance.

The other man who lived with him was very suspicious.

"We just called Mr. Tomoshi Tanaka based on the number on the business card."

"He said he was still out for a walk and didn't know what was going on at home."

"After we explained the situation to him, he was shocked and said he would be back soon."

Saying that, Mao Lilan's tone became a little subtle:

"But I think..."

"Mr. Tomoshi Tanaka seems very suspicious."

He happened to be out for a walk when the homicide happened at home.

Combined with the previous inferences, Mao Lilan naturally regarded Mr. Tomoshi Tanaka as a suspect.

"indeed so."

Lin Xinyi nodded in agreement.

However, seeing the slightly excited look on his apprentice's face, he still couldn't help pouring cold water:

"The suspect has been identified, which is a major breakthrough."

"But... we still have to find evidence to prove that he is the murderer."

"evidence?"

Mao Lilan was slightly taken aback:

"Hasn't the murder weapon been found?"

"The fingerprints of that Mr. Tomoshi Tanaka should be found on it, right?"

"Fingerprints can't explain anything." Lin Xinyi shook his head: "This is his home, and there are his fingerprints on that golf club, which is normal."

"Moreover, it's the same reason - this is where he lives, even if you find the dander and hair left by him at the scene, there is no way to prove that he killed someone."

"This...but..."

Mao Lilan said with some hesitation:

"We have proved that this is an acquaintance who committed the crime and forged the scene."

"He is the biggest suspect. If his fingerprints were found on the murder weapon, wouldn't that explain the problem?"

"No." Lin Xinyi shook his head:

"If he killed him with one bite, it was done by other acquaintances of the deceased. How should we refute it?"

"The so-called acquaintance may not have left any traces, and no one can prove his existence."

"However, we also cannot prove that he does not exist."

"If this acquaintance really exists, then if we directly designate Tanaka Zhishi as the murderer, wouldn't it be an unjust, false and wrong case?"

Mao Lilan couldn't help but choked slightly.

She suddenly discovered that the murderer, just like Lin Xinyi's girlfriend, was another Carl Sagan's dragon.

"And..." Lin Xinyi suddenly sighed slightly:

"If the murderer is really Mr. Tomoshi Tanaka, then he has another powerful weapon."

"What weapon?"

"Money." Lin Xinyi pointed to this luxuriously decorated villa:

"He has a lot of money and can hire a good enough lawyer."

"With those lawyers around, even if he uses interrogation psychology to induce him to confess his guilt honestly, when he thinks about it later, he can retract his confession in court."

"So, want to sue him...our evidence is not enough!"

Hearing this, Miss Maori couldn't help feeling a little dizzy:

The evidence has been collected to this point, but it is not enough.

After fighting the prisoner, he has to continue fighting the lawyer.

Alas... Mao Lilan sighed softly in her heart.

She suddenly missed those honest children she met with Xinyi before, who knelt down and cried bitterly as soon as the music played.

Chapter 180 Please help Xiao Ai

It's like a leek player who was forced to open a new version by Gou's plan...

Mao Lilan felt a little helpless that the "monster" seemed to be upgrading faster than her "player".

Now even if her childhood sweetheart who used to be a "strong version hero" is shot, I'm afraid she will have to be hanged and beaten like her father's "sewer character".

No way, times have changed.

He doesn't play tricks with you at all, he just asks you for evidence.

The most powerful and valuable evidence that can be found at a crime scene is DNA first, followed by footprints, and then fingerprints.

But now, because the number one suspect is the head of the house, the DNA and fingerprints left by him at the scene cannot be used as evidence to prove that he is the murderer to a large extent.

The footprints at the scene of the crime were flooded with flood water, and they were so damaged that they could not be extracted at all.

"No wonder the murderer wanted to wash the floor with a flood of water."

At this time, Mao Lilan came back to her senses belatedly:

"Perhaps he wasn't trying to cover his tracks at all."

"He was just trying to cover up the fact that there is no 'outsider' footprint in this villa!"

The floor that has been washed by water is like a warehouse that has been burned by fire.

Facing the ruins, even if someone suspected that the goods stored in the warehouse had been short-lived, no one could produce evidence.

Facing this messy scene at this moment, as investigators, Lin Xinyi, Mao Lilan and others could not determine whether there were any so-called "outsiders" at the scene.

"How to do…"

Ms. Mao Lilan, who was in charge of trace inspection, felt tremendous pressure.

She thought about it in a tangled state, and tentatively asked:

"Did you find any skin flakes from the murderer in the dead man's nails?"

"No." Shigemi Asai, who was in charge of the autopsy, gave a disappointing answer: "When I checked the autopsy form, I didn't find any skin flakes under the nails of the deceased."

Mao Lilan, who hit a dead end, fell into deep thought again.

After thinking about it for a while, her eyes brightened again, and she boldly guessed:

"Will the murderer's hands be stained with the blood of the dead?"
