"Hey, hey... What do you think of me like that? ”

Seeing everyone's stunned expressions of "seeing the strongest king play bronze operation", Lin Xinyi knew...

These people must have some misunderstanding of the profession of forensics:

"The forensic doctor is not a psychic, how can he solve the case directly every time he sees a corpse?"

"Don't make this work too easy!"

Autopsy is the most basic part of forensic work, and what can be found is very limited.

If it is really as others think, all cases can be solved by autopsy alone....

He used to be less tired when he used to work.

Not to mention the fact that you still have to read so many books and take so many classes, such as...

Physiology, biochemistry, pathology, and pathology of basic medicine.

Clinical medicine in surgery, internal medicine, obstetrics and gynecology, pediatrics, etc.

"Traditional Chinese Medicine" and "Acupuncture" of Chinese Medicine.

In addition, forensic medicine itself has more than a dozen professional courses such as "Field Studies", "Physical Evidence", and "Forensic Science and Technology"...

His college textbooks stacked up half a cut higher than his own.

After reading so many books, the results of the autopsy can solve all the problems?

If this can really work, is it worth the hair that fell out in his five years of college?!

Lin Xinyi felt a scorn in his heart, and finally explained in a calm tone:

"In this case, the murderer fired at a distance, killed with one shot, and left with one blow, leaving no evidence on the deceased at all."

"It's simply unrealistic to find out the truth just from the autopsy."

"That said..."

Sewa Zunde immediately misinterpreted Lin Shinichi's words with malicious intent:

"You can't find anything, can you?"

"So what are you wasting everyone's time for? Hurry up and get out with those useless cops! ”

The police officers who were named and humiliated again by "......" all had ugly faces.

But they didn't have the confidence to refute, so they could only project that aggrieved and resentful gaze onto Lin Xinyi:

Lin Management Officer... Aren't you amazing...

Use your invincible forensic knowledge to figure it out!

But Lin Xinyi didn't seem to see it at all.

He didn't explain much, he didn't look at the corpse, but like a detective, he began to carefully observe the environment at the scene.

"Alas... Looks like I'm going to have to do this time. ”

Kudo Shinichi sighed softly:

He stood in this room for a few minutes, and he had already seen through the murderer's modus operandi:

This room has a locked door, no windows and only a balcony.

So the murderer could only have come in from the balcony.

And the way he ascended to the balcony was very simple, it was nothing more than to climb out of the window of another room, and then step on the narrow eaves that protruded outwards on the outside of the wall, and move closer and closer to this room little by little.

In the end, the murderer jumped directly from the narrow eaves of the exterior wall 2 meters away to the balcony of this room with a rope tied to the rope used to return after the crime.

It's not elaborate at all, it's very easy to see.

And its only effect is to make people have a mindset that "the murderer must be a physically sound person who can climb the wall and jump long".

In this way, the police will only look for suspects who are young, strong, and in good health, and will ignore the older Seba Sontoku who has "injured his legs and feet".

"That's a good idea..."

"It's a pity that your luck isn't good."

Kudo Shinichi smiled slightly, and was ready to stand up directly to reveal the mystery.

Anyway, Lin Xinyi's performance this time was extremely bad, although he knew the answer in advance and was a little invincible, he must have won.

But at this moment... Lin Xinyi suddenly made a new move:

"What about the person in charge of the on-site investigation from the forensic section?"

"This, this!"

Immediately, several young police officers surrounded him.

Although Lin Xinyi's performance this time was disappointing, he is still very likely to become the future leader of the forensic class.

Therefore, the officers of these forensic sections spoke very politely:

"We are all forensic classes, field investigation departments."

"Mr. Lin Xinyi, do you have any instructions?"

Although Lin Xinyi's performance was not good this time, he could become a future leader, so the officers of these forensic classes were still extremely polite to him.

"Did you find any handprints and footprints at the site?"

"There is a lot of shooting and killing, and the killer must leave before the others follow the news."

"He must not have had time to clean up the scene, so he should have left some handprints and footprints on the scene."

Lin Xinyi calmly said his way to crack the case.

And when he said this, Mr. Seba, who was in a wheelchair, immediately laughed in his heart:

Hahahaha... Donkey skills are exhausted, right?

He wore gloves when committing the crime, and he did not leave fingerprints and palm prints at all, not even handprints.

The floor of the room is also a flat hard floor, so you won't leave a footprint when you step on it.

Want to use this stupid method that the police will use to catch him Sewa Sontoku? How naïve!

And the truth is just as Sentoku Sewa expected:

"Neither the handprints nor the footprints were found."

"A few fingerprints were found, but they couldn't be determined to be the murderer's."

"By the way, speaking of which..."

The officers from the forensic section thought for a moment, then questioned and asked:

"Mr. Lin Xinyi, it's useless to look for these things, right?"

"We asked, this is a room, although it has been a long time since guests have come to stay, but a maid comes here every day to clean it."

"Even if you can find handprints and footprints, there's no way to know if they belong to the murderer or the servants, right?"

"......." Lin Xinyi frowned slightly.

Hearing this, he knew that the level of these officers in the forensic bureau was indeed limited.

I only know how to bury my head inch by inch to find traces, but I don't know how to start from the facts of the case and restore the crime scene.

"Actually, you can tell."

"First of all, you can ask, do the servants here wear gloves when they clean up?"

Lin Xinyi asked.

The servant who was waiting next to him immediately replied very cooperatively:

"No, we only wear gloves when we clean the bathroom."

"That'll do."

Lin Xinyi said with a relaxed expression:

"Suppose the killer is among those suspects who are under control:"

"Since he was not detected with gunsmoke, it means that he must have been wearing gloves when committing the crime."

"And the maids here don't wear gloves when they clean the rooms."

"In this way, we only need to find the handprint without the palm print, and we can basically confirm that it is the mark left by the murderer."

"As for the footprints..."

Lin Xinyi paused slightly, and pointed to the balcony outside:

"This is a 'secret room', and the murderer can only climb in from the balcony and leave from the balcony."

"When he leaves, he will most likely step on the wall of the balcony to borrow strength, or step on the handrail of the balcony and return the same way over the balcony."

"And the maids who clean don't step on the walls and handrails."

"If we can pick up footprints on the walls of balconies and railings, it's probably the murderer's."

Forensic doctors must not only study corpses, but also understand trace investigation, analyze the scene, restore the case, and understand the profile of the perpetrator.

An old forensic doctor with enough practical experience can almost be said to be the king of the criminal investigation world.

So even if nothing was found on the corpse, Lin Xinyi could still reason the process of the crime.

"I see..."

The officers of the forensic section all showed a look of sudden realization.

However, in the next second, they poured a basin of cold water on Lin Xinyi again:

"But, we've seen it on the balcony too..."

"There are really no handprints or footprints there!"

Lin Xinyi: "......"

He could already smell something bad.

This feeling is as if the assistant I met during the autopsy was Komatsu patrolling ...

"That..."Lin Xinyi asked tentatively, "How did you find the handprints and footprints?" ”

"How? Several young officers looked at each other suspiciously: "There's no way... Just look with your eyes. ”

"Just with the naked eye?"

"You've always seen with your eyes?"

Lin Xinyi's expression suddenly became extremely exciting.

"yes, or else?" The officers replied rightly.

"What about blue lights, violet lights, multi-band light sources?"

The blue light is used to find sweat handprints, the purple light is used to find mineral oil handprints, and the multi-band light source is more versatile, which can find grease and sweat handprints that are difficult to distinguish with the naked eye on various smooth objects such as paper, wall skin, and imitations.

Although these devices should not be used in this case, Lin Xinyi still asked first.

Because these are the most widely used and most basic equipment in site investigation.

And the response of the officers of the scene investigation department of these forensic divisions was: "None of these..."

"....." Lin Xinyi was silent for a while, and then asked:

"Is there thiocyanic acid and potassium thiocyanate?"

"What about alizarin ethanol?"

These three are common chemicals used to visualize potentially dusty handprints.

"Ninhydrin solution, silver nitrate solution, is there any?"

These are common chemicals used to visualize latent sweat handprints.

And this time, the reaction of these young officers was:

“？？？？”

They had never heard of these awkward chemical terms.

"Forget it...."

"502 glue, there should always be this, right?"

The 502 glue visualization method is suitable for the visualization of latent sweat handprints on almost all non-permeable bodies.

Lin Xinyi didn't want to investigate the case now, he just wanted to see how lacking the basic investigation equipment of this forensic class was.

"502 glue?"

Sure enough, these young police officers looked confused:

"Does this also have to do with the site investigation?"

"You..."

Lin Xinyi choked violently:

"Why don't you have anything in the on-site investigation department?"

"So what the hell have you investigated?"

Even the most basic investigation equipment is not complete, no wonder they have successfully controlled the suspects, but they still have to ask for foreign help.

Otherwise, if the police can find the traces scientifically and effectively, how can detectives be needed in this case?

Thinking about it this way, pulling the crotch with the Metropolitan Police Department is not a search lesson at all, but being held back by your identification class!

"Wait..."

Lin Xin reacted in an instant.

He turned his head and looked at the Twilight Police Department with a grim expression:

"The Metropolitan Police Department gave me the care, is this the kind of forensic class?"
