"What, do you know the murderer?"

"Yes, yes, that big brother said he found the murderer and asked me to inform everyone to gather at the puppet warehouse on the second floor."

"There is no murderer. My eldest brother must have committed suicide." Takeda Yuzo, the third eldest son of the Takeda family, said.

"Let's go, Yong San. I think that top student from Dongda University should have some troubles. The murders that happened one after another are too terrifying. It would be good to hear an explanation."

"Then what other explanation can there be?" Old Mrs. Takeda walked out of the door and muttered, "It's obviously a curse from Master Spider. What kind of murder is there? It's a sin."

Conan smiled and said, "Big brother said that the police have been notified. If you don't go, you will be suspected of a major crime."

After saying that, Conan went to inform Kogoro Mori and Xiaolan without looking back. On the way, he kept thinking about what the sentence, "I underestimated Yukiho." exactly meant.

It's mysterious, what is hidden behind the two of them.

Notifying Xiaolan, Mouri Kogoro went to the puppet room on the second floor and swept away. Standing outside the door were members of the Takeda family, including the maid, and the foreigner Robert.

Only Karasawa Yukiho was missing at the scene, and Conan suppressed his doubts for the time being.

Standing next to the corpse was a tall, bright-eyed young forensic doctor. He had already put on milky-white professional gloves on his hands, and he was scanning the crowd with a calm expression.

"Hmph~"

The oldest wife of the Takeda family snorted coldly, tapped the ground heavily with a cane, and said dissatisfiedly, "Young man, this is Lord Spider's punishment for Shinichi. If you insist on making trouble over nothing, you will definitely suffer revenge from Lord Spider.

of."

Chen Jun ignored it and looked at everyone, "Does anyone have any objections to our investigation?"

Takeda Yuzo stood up, "This puppet house can only accommodate children. If it is not a punishment from Lord Spider, it would be suicide. How could it be killed?"

"Very good, you have asked two questions, and I will answer you accurately."

Takeda Shinichi's body had already been removed from the rope. Chen Jun slowly walked to the body, "First of all, it must be clear that the deceased Takeda Shinichi did die of homicide. It was neither a punishment from Master Spider nor a suicide.

I will give you a scientific explanation on this point."

"You all saw it when you entered the door before coming. The victim Shinichi Takeda was strangled by a rope around his neck and his body was entangled in a puppet net. But in fact, the wounds on his body were far more than this. This was not the real cause of his death. Accurately

In other words, he died while hanging."

"What?"

"impossible!"

Everyone in the Takeda family shouted. Even Conan was a little surprised. This involved a blind spot in his knowledge.

"The real cause of death of the victim Shinichi Takeda was craniocerebral injury and neurological death." Chen Jun did not care about the disgusting smell of blood emitting from the body, opened the body and said calmly:

"In the posterior part of the skull, there is a bowl-shaped depression and hematoma, which was formed by a strong impact with a heavy object, causing the victim's hard brain bones to be completely crushed, with a degree of crushing of more than 85%, accompanied by the rupture of the bridging veins in the subdural space.

It can lead to massive bleeding, acute swelling and blood clots forming in the brain, causing severe damage to the hypothalamus, brainstem, and cervical spinal nerves, leading to rapid death in a very short period of time."

"It's like you feel a sudden pain in the back of your head, and then your vision goes dark, and you lose all consciousness because you are already dead."

Takeda Yuzo, who had made the most noise just now, was stunned and speechless.

The rest of the people didn't say anything. They were all silent, looking at one person.

"If it is suicide by hanging or mechanical asphyxiation, the lack of oxygen and carbon dioxide storage in the body will stimulate the medullary respiratory system, resulting in deepened breathing, accelerated frequency, spasm of skeletal muscles throughout the body, dilated pupils, drooling, defecation or men*

*Phenomenon.

At the same time, due to mechanical violent suffocation and compression of the trachea, the base of the tongue will stick backward against the back wall of the throat and soft palate, causing the throat cavity to be blocked.

However, the above phenomena that were supposed to be suicide by hanging did not occur in the case of the victim Shinichi Takeda."

"This only proves that the victim died of homicide.

If it was suicide, do you think he would pick up the rope and put it around his neck? As for Lady Spider, I suggest she use spider silk for better results."

No one at the scene could laugh out loud, there was only silence.

In the face of scientific explanation, all speculations and ancient legends are vulnerable.

Takeda Ryuji asked, "There were no wooden sticks, iron rods or other things in the puppet room. How did the murderer kill my eldest brother?"

"No need for any wooden or iron rods."

"Such a powerful impact is difficult to achieve with just human mechanical strength."

Chen Jun picked up the flashlight on the ground, and a beam of light illuminated the dim warehouse beams, and a dark red reflection appeared. "Did you see the blood stains there? The victim was not knocked there, but hit there."

"The strong force pulled the victim's head and slammed it against the roof beam, causing a craniocerebral injury and instant death. Moreover, there was a fracture of the spine at the back of his neck. This can prove that he hit the roof beam with force."

“This, this, how is this done?

And the door here was locked tightly, how did he escape? Is this a secret room?" Takeda Ryuuji said in surprise.

"Of course this is a secret room, and the murderer's modus operandi is also very clever."

"But as long as you read more than 1,000 mystery novels, you will find that there is no perfect method of committing crimes in this world." Chen Jun looked at everyone and said softly, "There are only a few prerequisites for secret room murder methods."

"Concierge key type: To create a secret room, the key is to manipulate the key. Usually, only one concierge key can open the "secret room", but this key is either placed in the secret room, or it seems that the criminal has no chance

Get it, thus creating a secret room effect.

1. Swap the key.

2. Replace the special door lock.

3. Return outside the secret room: use a slingshot to shoot the key back to the room, train the kitten to carry the key, etc.

Psychological type: This type does not have special keys or door locks, but only uses human psychology and the killer's superb acting skills to create a secret room effect.

1. Substituting false information to create a fake death, disperse the crowd, and move the real body into the secret room.

2. Throw the key on the spot. This is the simplest and boldest method. That is, when everyone breaks into the secret room and makes a mess, throw the key on the spot.

3. Lurking in a secret room. This is also a bold approach, that is, hiding in the secret room after committing the crime until many people enter the scene, and then taking advantage of the chaos, they come out quietly. But one thing is that the murderer must appear in this place alone.

And those who will not be suspected, in other words, are insiders.

4. Acting in front of the door. It's obviously not a secret room, it's not locked, but you hold the key and pretend to unlock it, maybe twist it a few times, break out into a sweat or something, the effect will be better."

Takeda Ryuuji asked, "The key to the warehouse is only in the hands of my elder brother Takeda Shinichi. No one else has it, and the door lock has not been changed. It is even more impossible to lurk in the secret room. There are almost no blind spots here, even if you use a slingshot to shoot the key

When I came in, I didn’t find the key on the ground.”

Mouri Kogoro touched his chin and added, "Boy, you summarized it very well. This secret room killing method has aroused my interest. Please tell me."

Chen Jundao: "The above secret room murders are conventional techniques, and the murderer used two superimposed secret room methods in this secret room: reverse thinking + special skills."

"Reverse thinking? Special skill mechanism?" Mouri Kogoro chewed on these two words.

"That's right!"

A slight smile appeared on Chen Jun's lips, "Secret room murder does not necessarily require the murderer to be in the secret room, but may also be outside the secret room. Depending on specific mechanisms, the secret room effect can also be created. It is like a movie montage technique. At the same time,

What you see is not the whole picture."

"To complete this trick, a very clever mechanism is needed.

The murderer's method is to use fishing line, thumbtacks, puppet string, and rope to carry out secret room murders. The method is very simple.

First use the rope to make a loop for hanging on the beam, then pull one end of the rope around the window to fix it, then use a fishing line with small loops at both ends to pull out the four corners and fix it with thumbtacks. Then

Thread a long fishing line through the knot at the base of the rope loop and pass the fishing line through the central beam."

"That's all it takes."

When Chen Jun shined his flashlight, a delicate mechanism with a circle appeared beside the window just for the child's body to pass through. "Just like the simple mechanism I just built, in this dim environment, as long as the murderer takes the victim Nobu Takeda,

Once he is attracted to the window, and then he pulls the thread outside the window, he will be trapped and hanged."

"However, the murderer did not expect that the deceased could not bear the strong force, and he died after his head hit the beam."

"There are no flaws in your statement, but why did my eldest brother lock the door of the date place?" Takeda Ryuji was puzzled, "And if the person he was dating asked him to look out the window, then my eldest brother would definitely do it.

You must be suspicious."

"It's a good question, but the incident happened in a hurry. I will let the murderer explain these two points on his own initiative."

A detective should satisfy the audience's curiosity and desire for knowledge, but Chen Jun is now a temporary forensic doctor. The first thing he does is to identify the murderer with conclusive evidence. Other details are not relevant to the overall situation.

"etc."

A crisp and sweet voice sounded outside the door, accompanied by a familiar wisp of fragrance, sweeping away the gloomy and weird atmosphere in the puppet warehouse.

"Sister Xuesui!"

Xiaolan turned back, rushed over and hugged Xuesui, and immediately said in surprise, "You're not missing?"

"Of course she's not missing."

The two of them hugged each other tightly, and Xuesui looked at the tall young man with white gloves inside the door, "Of course, someone is still calm and composed, and he doesn't look anxious at all."

"Brother Ito, I'm actually very anxious, but I just seem to have guessed Sister Yukiho's intention."

"Yeah?"

Xuesui's bright red lips flashed into a proud smile, she raised her head, her snow-white swan neck was slender, and her lips and teeth were lightly parted:

"I can just answer these two seemingly insignificant questions from Mr. Long Er."
