Chapter 77 An easy case to solve, a difficult teammate to lead

Lin Xinyi didn't notice that the leader was inspecting his work with satisfaction.

He was now completely attracted by this special corpse in front of him:

“The wound surface is smooth, the wound edges are neat, and there are no sharp skin flaps caused by repeated cutting.”

"The head was severed obliquely from the third cervical vertebra."

"The broken ends of the bones are smooth and there are no repeated saw marks, chop marks, or cutting marks."

In short, the deceased's neck wound was very smooth.

And there are no traces of repeated cutting, and the trauma is a one-time formation.

It was as if his head had been chopped off with a single blow of a hundred-pound guillotine on the guillotine, and even the bones were instantly cut off.

But the thing is, this guy was on a high-speed roller coaster.

Who could pick up a machete in a place like this and strike the deceased's neck with the same force as the guillotine?

"How did the murderer do it?"

Lin Xinyi has never encountered such a bizarre case.

You know, beheading is a technical job.

There are bones, ligaments, and blood vessels in the neck. If you break the bones and connect the tendons, most people really can't cut them in two.

The few beheading cases he had encountered before were basically caused by the murderer repeatedly cutting the deceased with a sharp instrument in order to discard it into pieces after death.

This situation of the deceased being decapitated with a knife had never happened before in his career.

"Hand me your head."

He thought for a moment and gave instructions to Inspector Komatsu, who was serving as his assistant next to him.

The deceased's head was fortunately dropped into the carriage and was completely preserved.

"Ah?" Inspector Xiaosong's expression was very stiff.

"Hand over the deceased's head." Lin Xinyi added casually.

He was so focused on observing that he forgot that his assistant was actually a novice.

"Yes." Inspector Xiaosong hesitated for a moment, and finally picked up the head with a stiff face and slowly handed it over.

Lin Xinyi took the head without saying a word and tried to install the deceased's neck section.

This installation was able to be installed perfectly.

This shows that the murder weapon is not only some kind of "sharp weapon", but also has an extremely thin blade and is extremely fast to draw.

There is only a thin blood line at the interface between the neck and the head. Once connected like this, it seems as if the head and body are still connected together.

When the head and neck were connected together, Lin Xinyi discovered intuitively that the edge of the wound still had some slight curvature.

"I'm afraid the murder weapon was not a knife."

"The edge of the cut made by the knife should be straight, it cannot be curved like this."

"This kind of wound line is a line!"

Looking at the faint curved blood line on the neck of the deceased, Lin Xinyi finally found a familiar feeling.

He had actually seen similar wounds, but not on corpses.

That was what he saw from the on-site wound photos provided by a victim whose throat was cut by a kite string while riding a bicycle while doing human injury assessment.

Since the wound is similar to someone whose throat was cut by a kite string while riding a bicycle, the murderer’s method this time should be

"Beheading with a string on a speeding roller coaster?"

"When the roller coaster entered the downhill tunnel, he put a coil around the deceased's neck, and then found a way to fix the coil on the track or wall along the way, and used the speed of the roller coaster to chop off the deceased's head?"

Lin Xinyi speculated on a murder method.

But then he began to doubt himself:

"Is this really possible?"

The difficulty of operating this method is a bit too great.

It's a downhill roller coaster. It's good if it's a speed that doesn't make you cry. And you have to put coils around other people's necks?

Is this murder or acrobatics?

Lin Xinyi was still trapped by common sense in the real world. Even if he had guessed that the murder weapon was a thread, he did not dare to make a conclusion lightly.

"But if the murderer's killing methods are really that exaggerated."

"Then after he kills someone, he probably won't be able to clean up the murder props left at the scene."

Thinking of this, Lin Xinyi immediately turned his head and said to the forensics department police officer who was busy taking photos beside him:

"Contact the person responsible for investigating the crime scene and ask them if they found any suspicious items at the scene."

"No." The police officer replied directly.

"No?" Lin Xinyi was slightly startled: "You didn't even contact them, how do you know that they weren't found at the scene?"

"Forehead"

The police officer scratched his head innocently, pointed to his colleagues who were searching on the roller coaster and said:

"Aren't they here to investigate the scene?"

"There's no need to contact you. You can tell at a glance that they haven't discovered anything yet!"

"I"

Lin Xinyi opened his mouth in surprise:

"I'll let you go investigate the scene."

"You, you all gathered around this roller coaster to investigate when it reaches the end?"

"Where's the tunnel? Didn't anyone send someone over there?!!"

"No, no." A group of Teletubbies looked over with innocent eyes.

Lin Xinyi: ""

People died in tunnels, and the tunnels were the scene of the crime.

Instead of investigating the tunnel, these guys gathered around the roller coaster that had reached the end to look for clues.

"Are you here playing carving a boat and asking for a sword with me?!"

"Because the sword fell into the river from the stern of the boat, you just wait for the boat to arrive at the dock and then go to the stern to find the sword?!"

"Yeah, sorry!"

The police officers bowed and apologized with great sincerity.

But this kind of "craftsman spirit" of doing things in a clumsy way and apologizing professionally can no longer fool Lin Xinyi.

As a manager, he is about to be furious at the performance of his subordinates:

The murderer has been determined to be an acquaintance of the deceased in the car, and the scope is very limited.

And the loopholes in this murder method are so big that just by finding the murder weapon at the scene, the case can be solved directly with a high probability.

There is no need to use any scientific survey technology, just use a flashlight and use your eyes to find it inch by inch.

Just such a simple case

Are you going to trick me into carving a boat to find a sword?

No wonder the detective always gets the limelight and fails to use opportunities given to you!

"Now, immediately, immediately, go to the tunnel to investigate!"

Lin Xinyi had never yelled at his juniors before, even though those newcomers might have made many mistakes.

But this time, these investigation police officers who only took photos and showed off their cuteness completely exhausted his patience.

It’s so tiring to lead these pig teammates.

It was like playing a 1V9 fair competition game. Lin Xinyi was so angry that he wanted to vomit blood.

Gin looked on silently, expressing that he understood very well.

"By the way, remember to bring Caesar with you!"

"The murder weapon must be stained with the blood of the deceased. Let the dog find it. Just follow the dog!"

Lin Xinyi specifically added.

Fortunately, he brought Caesar with him this time.

Without this ace police officer, I wonder if those full-time photographers would have missed any clues.

"well"

Lin Xinyi sighed helplessly as he watched Caesar leading the Forensic Division police officers away in a hurry.

What he didn't expect was that

His teammates were able to come up with new tricks for him.

Not long after the police officers who went to the tunnel investigation site left, the police officers responsible for searching several key suspects suddenly made a discovery:

"Manager Lin, Mu Mu Police Department!"

"We found a bloody fruit knife in the bag of the deceased's girlfriend!"

"What?!" Everyone looked sideways: "Is there a murder weapon in that woman's bag?"

Suddenly, the deceased's girlfriend, the lady named Aiko, became the focus of everyone's attention.

“It’s not impossible”

"Why is there such a thing in my bag?"

"This knife isn't mine, it's not mine! It's not mine!"

That Miss Aiko was obviously frightened by this scene.

Her incoherent explanation only made everyone more suspicious:

"What? The murderer was found so easily."

"I thought that woman was suspicious."

"It's probably a couple quarreling. Women are terrible."

Such comments soon erupted among the onlookers.

And Vodka also took the opportunity to come out and make noise:

"Hey, haven't you caught the murderer?!"

"Get us out quickly!"

"Uh" Officer Memu hesitated for a while.

Finally, in the midst of this excitement, Officer Megure pointed at Ms. Aiko and said:

"Okay! Bring the female suspect back to the station for interrogation!"

Lin Xinyi: "????"

Mumu Police Department

It's okay for those people to just follow along and make noise, why are you following along and making nonsense? !

Can such a low-level frame-up trick really deceive you, an old detective?

It's just pretending, right? It must be pretending to make the real murderer take it lightly.

Lin Xinyi took the initiative to think of the police department shown on the first level and moved it to the third level.

After all, you don’t need to understand autopsy knowledge, just think about it with normal people’s thinking

How do you chop off a person's head with a small fruit knife? !

Beheading is really difficult to do.

Not to mention a delicate woman, even an untrained man cannot do it.

To give the most intuitive example:

When the famous writer Yukio Mishima committed suicide by caesarean section, he asked his friend to hold the famous sword "Seki Magoroku" to explain his fault.

As a result, the friend took a famous knife and chopped three times on Mr. Mishima's neck. Not only did he not succeed in decapitating his head, he even failed to kill him.

In the end, he temporarily replaced a person who had practiced Iai Kendo, and he finally succeeded in cutting off the head with one sword and successfully completed the task.

Beheading requires skill, strength, a good knife, and a strong and stable mentality.

A man holding a famous sword could not successfully correct his friend's fault.

Now the people, and even the police, actually suspect that a woman can chop off her boyfriend's head with a fruit knife.

Could it be that she is a hidden great swordsman?

Hey, wait a minute

If it were in this world, it would not be impossible for a great swordsman or something like that.

Thinking of the performances of Kyogoku Makoto, Mao Lilan and others, Lin Xinyi's mood suddenly became complicated.

It seems that the Mumu Police Department is indeed watertight.

He even considered that "the murderer might be a great swordsman".

Thinking of this, Lin Xinyi finally realized the foresight of his colleagues.
