About 20 minutes later, a team from the Metropolitan Police Department arrived at the scene.

Naturally, it also included the forensic team headed by Lin Shinichi, Mao Lilan and Asai Narumi.

When you come to the scene, the first thing you need to do is naturally to understand the basic situation with the informant.

And after seeing those little informants...

"Conan, you're the informant?"

Mao Lilan, who had just received a call from the police and hurried from home, did not expect to meet Conan here.

Lin Xinyi was not shocked by Conan's appearance at all.

At most, I sighed that the school's sealing effect on the Grim Reaper was not as good as I imagined, and I couldn't manage it for a day, and it would fail when I walked out of the school gate.

What surprised him was: "Xiao Wai? ”

Seeing that his little girlfriend was also at the scene, Lin Xinyi was a little surprised.

But he quickly figured out that Xiao Ai must have been affected by Conan's aura of bad luck and was involved in this case.

Alas... Why don't you listen to me, or do you fool around with Conan's little pervert?

Lin Xinyi was a little depressed.

But now that the murder is now, it is not the time to teach children to pay attention to making friends carefully.

What's more, Gray Yuanai's identity is sensitive, Lin Xinyi is not good in front of people for the time being, and he is too familiar with her.

"Forget it, let's investigate the case first."

So, pretending not to know his girlfriend, Lin Xinyi learned about the case from Conan, who was the informant, in a serious manner.

"You saw a body in the bathroom of that villa twenty minutes ago?"

"That's right." Conan nodded, and deliberately added:

"For more than 20 minutes, we have been hiding across the road and secretly observing."

"The main entrance to that villa was never opened, and no one was seen coming in or out from this side."

"As for the sound..."

"Because it's across the road, there are all kinds of noise disturbances on the road."

"We can't hear if there's any sound coming from the villa."

As an eyewitness, Conan can still play a big role.

Under his methodical narration, Lin Xinyi quickly grasped the facts of the case.

And the more timely the on-site investigation, the better, and the later it is, there is a possibility of missing any important clues.

Therefore, Lin Xinyi didn't bother to say hello to Miss Gray Yuan, who had been silently watching him beside him, so he turned around and said to Mao Lilan, who was serving as an assistant beside him:

"Let's go, let's go into the villa now."

"Hmm." Maolilan nodded.

She didn't care why Conan was here, so she turned around and followed Lin Xinyi towards the villa.

Conan was left behind by the two of them, blocked outside the courtyard gate of the villa, and felt a little uncomfortable:

He suddenly found that he didn't know when he started, and he was even a little accustomed to this kind of soy sauce life that was left behind by Xiaolan and Lin Xinyi, and he was not even qualified to enter the crime scene.

As a former detective, this is undoubtedly a sadness.

Conan couldn't help but sigh for his life's chances.

At this time, Gray Yuan Wai quietly leaned into his ear and said in a cold tone:

"Hey, Kudo, can you tell your girlfriend:"

"Tell her to keep her distance and stay away from my boyfriend."

Conan: "......"

I still want to say that!

But Xiaolan has become Lin Xinyi's personal assistant, and no matter how much she keeps it, she can't keep it far.

It's okay to watch his girlfriend investigate the case with other men, but now he still has to listen to that man's girlfriend speak coldly to him, asking his girlfriend to stay away from that man.

Alas... What is this called?

Conan was very aggrieved.

I saw Lin Xinyi, who had just walked into the courtyard door of the villa, suddenly retreated with a gloomy face.

"Why, do you have anything else to ask me?" Conan was puzzled.

But Lin Xinyi came to him and squatted down, and said with a serious expression:

"Who told you to talk to my girlfriend like this?"

"I warn you, you must maintain a social distance of more than one meter when talking to her, and you can't get too close!"

Conan: "......"

Obviously, it's because you and my girlfriend are too close, and your girlfriend came over to talk to me in order to keep my girlfriend away from you!

Thinking of this complicated relationship like a tongue twister, the great detective suddenly felt even more aggrieved.

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

After teaching Conan a lesson, Lin Xinyi quickly returned his attention to the case itself.

He led the team to the door of the villa first and tried to ring the doorbell.

There was no answer from inside the door.

Take a closer look at the lock of that door:

"The door is closed, there is no sign of a lock-picking."

"Go to the window over there and see if the body is still in the bathroom, as the informant said."

Lin Xinyi carefully checked the door lock, turned his head and commanded his subordinates.

Several police officers walked to the courtyard on the side of the villa, and under Conan's instructions, leaned their heads in front of the window of the bathroom:

"The corpse... The corpse is still inside! ”

"Steward Lin, that's right, there's a corpse in that bathroom!"

The killer does not seem to have disposed of the body at all.

The scene in the bathroom was almost exactly the same as what Conan had seen more than twenty minutes ago.

The shower head on the bathtub was still draining, washing the corpses below, as well as the bathroom floor.

"There is no difference between the scene and the sightings described by Conan."

"Could it be that the murderer left this villa twenty minutes ago, when Conan found the body?"

Lin Xinyi secretly speculated in his heart.

At this time, several police officers who circled around the villa soon brought a new discovery:

"Administrator Lin, the floor-to-ceiling glass door on the other side of the villa is broken!"

"The killer probably broke the glass door and broke into the villa through the yard."

"Oh? Take me to see it. ”

Lin Xinyi followed around to the other side of the villa, only to see that the situation was indeed as those police officers said:

The floor-to-ceiling glass door was violently shattered, and large pieces of glass were scattered all over the ground.

Through the glass door, you can see the living room inside:

The living room was a mess.

The drawers of the coffee table and TV cabinet were rudely opened.

The contents stored inside were indiscriminately picked up and scattered all over the ground.

At first glance, this scene makes people involuntarily give birth to a guess:

"Thieves here?"

And in addition, what is even more strange is:

"How can there be so much water on the living room floor?"

"No, it's not just the living room... Why is there water everywhere on the floor of this villa? ”

Seeing the strange scene in front of him, which seemed to be like a flood, the shallow well who accompanied Lin Xinyi couldn't help but be a little stunned and confused.

And it was only when he cautiously walked through the broken glass door into the villa that he realized:

It turned out that the faucet in the villa was always on.

And it's not one faucet that's on, it's all the faucets in the kitchen, bathroom, laundry, etc.

The faucets were turned on to the maximum, and the pools below were plugged up.

The excess tap water overflowed the pool and flowed to the ground, covering almost every floor on the first floor of the villa.

"This was done by the murderer?"

"Why did he turn on the faucet and soak the floor?"

Asai has never seen such a scene before, so I can't help but be a little curious.

And Mao Lilan, who is mainly responsible for trace work, has already sensed the smell of trouble from the strange scene in front of him:

"The murderer let the floor accumulate water, probably to hide the traces."

"That's right."

Lin Xinyi echoed with a serious expression:

"This guy has a strong sense of anti-reconnaissance."

"He washed the floor with a lot of tap water, destroying the blood stains and dust footprints that might be on the floor."

"It's a huge hassle for our site survey work."

"And, you see..."

He paused slightly, and pointed to the broken glass door:

"Outside the glass door is the lawn, and outside the lawn is the rough road surface."

"You know, it's hard to extract footprints with complete shapes on relatively rough and uneven objects such as lawns and cement roads."

"If the killer was entering and exiting the scene via the road and the lawn, it would be almost impossible for us to extract the killer's footprints outside the house."

"The floor inside the villa was washed away by the water, and it was extremely difficult to extract the dust footprints."

"That is to say..."

"The footprints, the extremely important traces at the scene, have been almost cleaned up by the murderer."

"This..."Hearing this, everyone's eyes became a little solemn.

Especially Mao Lilan, who is in charge of the trace inspection work, she said with some worry:

"The murderer's mind is so meticulous, I'm afraid it's not just footprints..."

"I guess fingerprints, dander, these samples will also be difficult to collect, right?"

Since the other party knows how to clean up the footprints with a large amount of water, he will definitely not forget the other two key traces.

And what's even more troublesome...

"There are obvious traces of turning at the scene, and the items are scattered, which is very similar to an outsider's burglary, robbery, and murder after accidentally clashing with the owner of the house."

"If this is the case, then the murderer and the deceased may not have any social relations at all."

"If you can't find the key clues of footprints and fingerprints... Isn't there nothing we can do to lock down the identity of the murderer? ”

Maoliran frowned tightly, and Asai Narumi was also meditating.

The atmosphere quietly became solemn.

But Lin Xinyi shook his head gently:

"No, maybe, it will give us a clear direction for the investigation."

"What do you mean?" Mao Liran and Asai Narumi were both a little puzzled: "The scene has been destroyed like this, is it still good for the investigation?" ”

"It's because the site was cleaned up so thoroughly that it makes people suspicious."

Lin Xinyi explained in an orderly manner:

"Burglary and murder, burglary and murder, the murderer's original purpose is to make money."

"They often kill people on impulse, and they are unfamiliar with the location of the crime, and they often dare not stay long after the killing."

"It is very rare in actual cases that people can calmly stay at the scene after the murder and patiently clean up the traces as if they were premeditating murder."

"Generally speaking, when there are signs of burglary in the house where the contents of the house have been turned over, and when the murderer patiently cleans up the traces, both appear at the same time..."

"The truth is often that acquaintances commit crimes, falsify the scene, and want to throw the murderous black pot onto the non-existent burglars."

"They are afraid that the traces left on the scene will expose themselves, so they will spend so much effort to clean up the place without three hundred taels of silver."

Based on his own experience in handling cases, Lin Xinyi told his own speculation.

But just talking about experience, it is obviously impossible to convince Mao Lilan and Asai Narumi, who have been "brainwashed" by him, and have become more evidence-heavy and lighter reasoning.

"You can't make a conclusion just by speculating!"

"Is there any evidence that can prove your statement, Mr. Lin?"

"It's up to everyone."

Lin Xinyi did not give a conclusion by reasoning alone, but commanded in a calm tone:

"Guys, let's start scouting."

"The murderer is already giving us a war letter."

"Let's see how clean he can clean up the scene!"
