Coroner Ke Xue

"Hey, why are you looking at me like this?"

Seeing everyone's stunned expressions of "seeing the strongest king perform bronze operations", Lin Xinyi knew

These people must have some misunderstanding about the profession of forensic medicine:

"Forensic doctors are not psychics, how can they directly solve the case every time they see a corpse?"

"Don't think this job is too simple!"

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

If it is as others imagine, all cases can be solved by just relying on corpse examination

He wouldn't be so tired when he worked before.

Not to mention having to read so many books and take so many classes, for example

Basic medical physiology, biochemistry, pathology, pathology, etc.

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

Traditional Chinese Medicine and Acupuncture.

In addition, more than a dozen professional courses such as "Field Science", "Physical Evidence Science", and "Criminal Science and Technology" are provided by forensic medicine.

The stack of his university textbooks is half as high as his own.

After reading so many books, it turns out that cadaver examination can solve all problems?

If this is really possible, is it worth the hair he lost during the five years of college? !

Lin Xinyi felt a burst of curse in his heart, and finally explained in a calm tone:

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

"It is simply unrealistic to find out the truth just from the body examination."

"That means"

Seba Tundoku immediately misinterpreted Lin Xinyi's words with malicious intent:

"You can't find anything at all?"

"Then why are you wasting everyone's time? Get out of here with those useless police officers!"

""The police officers who were named and shamed again looked ugly.

But they didn't have the confidence to refute, so they could only cast their aggrieved and resentful eyes on Lin Xinyi:

Manager Lin, aren’t you awesome?

Use your invincible forensic knowledge to think of a solution!

But Lin Xinyi seemed not to see it at all.

He no longer explained or observed the corpse. Instead, like a detective, he began to carefully observe the environment at the scene.

"Well, it seems that I really have to come this time."

Kudo Shinichi sighed softly:

He stood in this room for a few minutes and already saw 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.

The way he climbed onto the balcony was also very simple. He just climbed out of the window of another room, stepped on the narrow eaves protruding outwards on the outside of the wall, and moved closer to this room little by little.

Finally, the murderer tied a rope for returning after committing the crime and jumped directly from the narrow eaves of the outer wall 2 meters away to the balcony of this house.

This technique is not subtle at all and is very easy to see through.

Its only function is to create a mindset that "the murderer must be an able-bodied person who can climb walls and jump long distances."

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

“It’s a good idea”

"It's a pity that you are not very lucky."

Kudo Shinichi smiled slightly and was ready to stand up and reveal the answer.

Anyway, Lin Xinyi's performance this time was extremely poor. Although he knew the answer in advance and was somewhat defeated, he must have won.

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

"What about the person in the forensics department who is responsible for the on-site investigation?"

"Here, here it is!"

Immediately several young police officers gathered around him.

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

Therefore, the police officers from the forensics section all spoke very politely:

"We are all from the forensics class and the field investigation department."

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

Although Lin Xinyi performed poorly this time, he could eventually become a future leader, so the police officers in the forensics department still spoke to him extremely politely.

"Did you find any handprints or footprints at the scene?"

"The noise of shooting and killing people is not small. The murderer must leave before others follow the sound and arrive."

"He must not have had time to clean up the scene. He should have left some fingerprints and footprints on the scene."

Lin Xinyi calmly explained his method of solving the case.

And after hearing what he said, Mr. Seba, who was sitting in a wheelchair, immediately laughed in his heart:

Hahahaha, is Guizhou Donkey exhausted?

He wore gloves when he committed the crime, leaving no fingerprints or palm prints at all, not even handprints.

The floor of the room is also flat and hard, and will not leave any footprints when you step on it.

Do you want to use this stupid method that the police will use to catch him Seba Tundoku? too naive!

And the fact is just as Seba Tundoku expected:

"No handprints or footprints were found."

"A few fingerprints were found, but they cannot be confirmed to be those of the murderer."

"Right, let's talk about it"

The police officers from the forensics department thought for a moment and then questioned:

"Mr. Lin Xinyi, is it useless to look for these things?"

"We asked, this is a guest room. Although no guests have stayed here for a long time, maids come here to clean it every day."

"Even if we can find handprints, footprints, etc., there's no way to confirm whether they belong to the murderer or the servants, right?"

"" Lin Xinyi frowned slightly.

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

I only know how to look for traces inch by inch, but I don’t know how to reconstruct the crime scene based on the facts of the case.

"You can actually tell the difference."

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

Lin Xinyi asked.

The servant waiting next to him immediately responded cooperatively:

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

"That's fine."

Lin Xinyi said with a relaxed expression:

"Assuming the murderer is among the suspects who have been controlled:"

"Since he was not tested for gun smoke reaction, it means that he must have been wearing gloves when committing the crime."

"And the maids here don't wear gloves when cleaning the guest rooms."

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

"As for the footprints"

Lin Xinyi paused slightly and pointed to the balcony outside:

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

"When he left, he would probably step on the wall of the balcony to gain strength, or step on the handrail of the balcony, and climb over the balcony to return the same way."

"And the cleaning servants don't step on the walls and handrails."

"If we can extract footprints on the balcony wall and guardrail handrails, they are probably those of the murderer."

In actual technical investigation work, forensic scientists not only need to study corpses, but also know how to detect traces, analyze scenes, restore the facts of the case, and profile criminals.

Only by integrating this knowledge can we know how to find the key clues that can really promote the case from the corpses and various traces at the scene.

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

Therefore, even if nothing was found on the body, Lin Xinyi could still reason about the incident in a coherent manner.

"I see"

The police officers in the forensics department all looked as if they were suddenly enlightened.

However, the next second, they poured cold water on Lin Xinyi:

"But we've also seen it from the balcony."

"There are indeed no fingerprints or footprints there!"

Lin Xinyi: ""

He already smelled something bad.

It felt like the assistant I met during the autopsy was Inspector Komatsu.

"Um," Lin Xinyi asked tentatively, "how did you find fingerprints and footprints?"

"Method? Several young police officers looked at each other in confusion: "If there is no method, just use your eyes. "

"Just see it with the naked eye?"

"Have you always seen only with your eyes?"

Lin Xinyi's expression suddenly became extremely exciting.

"Yes, what else?" the police officers replied matter-of-factly.

"What about blue light, purple light, and multi-band light sources?"

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

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

Because these are the most commonly used and basic equipment in on-site surveys.

However, the reaction of the police officers from the Forensic Division's On-site Investigation Department was: "None of these."

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

"Are there any thiocyanic acid and potassium thiocyanate?"

"Where's the alizarin ethanol solution?"

These three are common chemicals used to reveal potential dust fingerprints.

"Ninhydrin solution, silver nitrate solution, do you have any?"

These two are common chemicals used to reveal latent sweat fingerprints.

But this time, the reaction of these young police officers was:

"????"

They have simply never heard of these awkward chemical terms.

"never mind"

"502 glue, you should have this, right?"

The 502 glue display method is suitable for displaying potential sweat fingerprints 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 was in this forensic class.

"502 glue?"

Sure enough, these young police officers looked confused:

"Is this also related to the on-site investigation work?"

"you"

Lin Xinyi choked hard:

"How come your on-site investigation department doesn't have anything?"

"Then what exactly did you investigate?"

Even the most basic investigation equipment is not equipped. No wonder they have successfully controlled the suspect, but they still have to call in foreign aid.

Otherwise, if the police can find traces scientifically and effectively, why would there be a need for detectives in this case?

Thinking about it this way, the person who was cooperating with the Metropolitan Police Department was not the search class at all, but was held back by your forensics class!

"etc"

Lin Xin reacted instantly.

He turned his head and looked at the Memu Police Department with a look of resentment:

"Is this the forensic course that the Metropolitan Police Department is responsible for?"
