Chapter 179: Falsifying Evidence at the Scene

Confidently, Maolilan came over to report on the findings of the trace team she led.

At this moment, she is the real protagonist of the audience's attention.

Looking at the student's radiant and shining appearance, Lin Xinyi, who has been playing soy sauce until now, does not feel lost, but just feels gratified:

As the leader of the forensic class, he hopes that his subordinates will be as capable as possible.

When the level of Mao Lilan, Asai Narumi and others can reach the point of being in charge, he will be able to be a fish guy who gets off work on time and go home early to accompany the children.

"So, Miss Maori..."

Lin Xinyi looked at Mao Lilan expectantly and approvingly:

"Tell us about your findings!"

"Well, Mr. Hayashi, Dr. Asai, come with me."

Mao Lilan suppressed the small excitement in his heart, and turned around competently to lead the way for Lin Shinichi and Asai Narumi.

The group soon walked out of the villa and came to the broken glass door, by the lawn laid in the courtyard.

"Our on-site investigation team has confirmed that all the doors and windows of the villa are locked from the inside, and there are no signs of violent damage."

"The only thing that shows signs of violent destruction is this smashed glass door."

"Judging from the situation on the spot, our first guess will only be:"

"The murderer entered through the courtyard gate, then stepped on the lawn to detour to the side of the villa, smashed the glass door on the side, and forcibly broke in."

"But Mr. Lin, look at the footprints on this lawn—"

As he spoke, Maolilan reached out to the lawn, the clump of grass that had been marked by the evidence plaque, and the fallen blades of grass.

It is difficult to extract complete footprints from the lawn, and there is no way to analyze important information such as the height, weight, and shoe type of the murderer like the footprints printed on the mud and the pattern is clearly recognizable.

But at the very least, the investigators were able to tell if anyone had walked past the grass by the blades of grass that had been trampled down on the lawn, and where they had passed as they walked by.

By judging the direction of the blades of grass and the rough outline of the footprints, it is also possible to analyze the direction in which the murderer is traveling.

"There are a series of footprints on the lawn, yes."

"But the strange thing is that after this series of footprints extends from the glass door on the side of the villa, it is time to turn to the main entrance of the villa and walk out of the courtyard gate... It's gone. ”

Indeed, the truth is as Maoliland says...

The trail of footprints on the lawn, before it reached the edge of the lawn near the main entrance of the villa, broke in the last section.

"Why are there such strange footprints?"

Mao Lilan paused slightly, and told Lin Xinyi his guess:

"I think the truth may be this:"

"When Conan found the body, the murderer was probably still in this villa."

"And when he came out of the glass door on the side of the villa, he originally wanted to fake the traces of outsiders entering and exiting by stepping on the lawn."

"But when the murderer walked around the corner of the villa, near the gate of the villa—"

He suddenly saw that by the phone booth across the road from the villa, Conan and the others did not leave, but stayed there to observe the villa.

"So, the murderer knew that if he went any further, he would be discovered by Conan and the others across the road."

"Moreover, there are people watching outside, and it is very unsafe for him to stand in the yard again."

So, he simply gave up continuing to forge footprints and turned around and returned to the villa.

The situation is as Maoliland said.

At the corner of the villa where the footprints disappeared, because of the change of perspective, you can just see the phone booth where Conan and others are hiding across the road through the courtyard gate.

Based on this, it is inferred that the murderer gave up and continued to forge footprints because he saw Conan squatting there, and there is indeed a trace of truth.

"But..."

Lin Xinyi couldn't bear to dampen the enthusiasm of the students, but he still couldn't help but say:

"It's just reasoning, not evidence."

The part of the lawn in front of the villa does not have footprints.

But this distance is not long enough, even, very short.

It's so short that it's just a little bit larger than the normal step size.

In extreme cases, maybe the murderer suddenly got interested in coming here, took a big step, and jumped this short distance.

It's certainly counterintuitive, but anyway...

It's a bit reluctant to infer that this is a murderer's forged footprint based on this strange footprint.

Mao Lilan's tirade, in the final analysis, is just detective reasoning.

"This kind of finding can be used as a reference for criminal profiling and help us clarify the direction of the investigation."

"But if it is used as evidence to prove that this is a fake scene, it is still somewhat insufficient."

Lin Xin corrected Mao Lilan's mistake with a serious word.

He didn't want his good student to be influenced by her childhood sweetheart's style and go astray.

But Mao Lilan showed a confident smile at him as if he had been prepared:

"I know, Mr. Lin."

"The few footprints that are missing alone don't prove my suspicions."

"But when you combine that with the marks on that broken glass door, it's a different story."

"Oh? Cullet? ”

Lin Xinyi looked at Mao Lilan's gaze and suddenly had confidence.

When he heard her mention the broken glass door, he knew that his students should have found the right direction of investigation.

Because he had taught Maorilan how to inspect and analyze the marks on broken glass.

"First of all, we can see through the part of the glass that remains on this broken glass door that has not fallen to the ground:"

"The side of the glass facing the inside of the room is less dusty."

"On the outside side, there's a lot of dust."

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

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

"Then, we spliced the glass fragments and carried out a holistic inspection to determine the point where the glass was first subjected to force and the radiation cracks that formed."

"Then change the angle of the light to observe the radial crack section."

"We found that there was a 'single-blade-like' bow pattern on the cross-section."

"And the convergence direction is towards the less dusty side, the side towards the inside of the room."

According to the principle of glass crushing by mechanical load, after being crushed by force, the broken section of the glass will form a visible arch pattern.

These bow patterns actually reflect the mechanical waveform of the force spreading across the glass.

Therefore, the convergence direction of the arcus pattern is extended in the direction, and the point where it converges is the specific force action point.

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

"So, we can be sure:"

"When the glass breaks for the first time due to an external force, the force should be on the inside side of the glass."

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

"It should have been the murderer who applied action to the glass from the inside of the house to the outside of the house and shattered it."

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

"This is an acquaintance who committed a crime, faking the scene of a murder and robbery."

Maolilan's eyes gleamed with confidence, and he spoke his own assertions.

"Very well, Miss Maori, you are doing a good job."

Lin Xinyi was very pleased to praise:

The strange footprints on the lawn, the form of the injuries suffered by the deceased with excessive violence, and the solid evidence that Maolilan found from the glass door using scientific analysis.

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

"Not only that," Morilan continued:

"During the investigation, our on-site investigation 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 by the clothes in the bedroom, they are all adult men."

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

"And the manuscript found in the other room was signed 'Kazuyu Tanaka'."

"The two of them should be related."

"And the deceased, perhaps, is one of them."

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

The other man who lived with him was very suspicious.

"We just called Mr. Tomosaki 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."

"When we explained the situation to him, he was shocked and said he would be back right away."

As he spoke, Maolilan's tone became a little subtle:

"But I think..."

"This Mr. Tanaka seems to be very suspicious."

When the murder occurred at home, he happened to be out for a walk.

Combined with the previous inference, it is natural for Mao Lilan to regard this Mr. Tanaka Tomosaki as a suspect.

"That's true."

Lin Xinyi nodded in agreement.

However, seeing the slightly excited look on his apprentice's face, he couldn't help but pour a basin of cold water:

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

"But... We have to find another proof that he is the murderer. ”

"Evidence?"

Mao Lilan was slightly stunned:

"Isn't the murder weapon already found?"

"I think you can find the fingerprints of Mr. Tomoshi Tanaka on it, right?"

"Fingerprints don't say much." Lin Xinyi shook his head: "This is his home, and there are his fingerprints on that golf club, which is normal." ”

"And, by the same token—this is where he lives, and even if the dander and hair left behind by him are found at the scene, there is no way to prove that he killed him."

"It's... But..."

Mao Lilan said with some hesitation:

"We have proven that this is an acquaintance who committed the crime and faked the scene."

"He's the biggest suspect, and finding his fingerprints on the murder weapon doesn't it tell the story?"

"I can't." Lin Xinyi shook his head:

"If he bites to death, this is the work of other acquaintances of the deceased, how can we refute it?"

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

"But, we can't prove it either, he doesn't exist."

"If this acquaintance really exists, then we will directly identify Tanaka Zhishi as the murderer, wouldn't we have made an unjust, false and wrongful case?"

Maolilan couldn't help but choke slightly.

She suddenly discovered that the murderer was just like Lin Xinyi's girlfriend, and he was a dragon of Carl Sagan.

"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."

"There are those lawyers here, even if the psychology of interrogation is used to induce him to admit his guilt honestly, he can later retract his confession in court."

"So, I want to sue him... Our evidence is not enough! ”

Hearing this, Miss Maori couldn't help but have a little big head:

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

After fighting the prisoners, you have to continue to fight the lawyers.

Alas... Maolilan sighed softly in his heart.

She suddenly missed a little nostalgic for the honest children she had met with Shinichi before, those honest children who knelt on the ground and cried as soon as the BGM sounded.
