All Worlds Madhouse

"Criminal Psychology" Department at the University of Rochester.

In order to better see the picture on the projection screen, the lights were not turned on in the entire classroom. With only weak light, a man in his 30s was seen standing on the podium.

“The human brain can be subdivided into different areas such as frontal lobe, parietal lobe, and temporal lobe, and each part has its own function. For example, the frontal lobe controls our ability to analyze things or control emotions. The parietal lobe is responsible for people's touch, logic, attention and spatial recognition."

Following his words, a corpse appeared on the projection screen.

People who study criminal psychology always have to deal with corpses, but when they saw the picture on the screen, there were still a few unnatural and disgusting murmurs coming from below the podium.

It's not because this corpse is so disgusting. For these students, they have seen many corpses no matter how disgusting they are. These mutterings are because this corpse has an extremely inconsistent sense of mutilation.

This is the corpse of a slightly fat middle-aged man. The skin is bright and there are no spots or wounds on the body. It can be said to be intact. With just one glance, you can roughly deduce that this corpse must not have been dead for more than 12 years. Hours.

However, this man's skull was missing a piece. It was not the kind that was crushed by a blunt instrument, but it was extremely neat, and the entire ring was cut off one centimeter above the eyebrow.

"Name: Andrew Naber, a brain surgeon. His body was found on the south bank of the Dowe River this morning." The person on the podium continued: "No, more accurately, he was in a He was in a coma state with weak signs of life remaining. At that time, he collapsed on the shore wearing a suit and ties, and his cause of death was due to infection during the transportation and rescue process."

There was another commotion in the audience.

The lecturer Will did not ask everyone to be quiet, but just switched the photo on the screen, which was a close-up of the head incision: "The incision in the skull surgery is very smooth, there is almost no bleeding, the main blood vessels are tied, and other The blood vessels were local anesthetized or sealed, but there was no damage to the blood vessels inside the brain. Judging from the dryness of the small amount of blood at the edge of the incision, it is estimated that the deceased had exposed his brain to the air for at least 6 hours. The most important thing is that the deceased's brain had a large Loss of square footage.”

"Lost?" A student sitting in the front row was confused.

"Yes, lost. Small parts of the deceased's prefrontal lobe, temporal lobe, and parietal lobe were lost. This kind of damage is very subtle. The simple extraction of brain tissue avoided all blood vessels. The damage was even greater than that of some brains. Patients with infarcts have milder infarcts. In short, this allows the deceased to continue to live despite the loss of brain tissue."

"The murderer must have extremely superb surgical skills, which can eliminate many search directions." A student said again.

Will nodded: "That's true, but the deceased worked in a hospital, and there were too many people with this ability in the social circle. Besides, just being limited to the circle of "doctors" would have a big blind spot, so the police There’s no way to lock down a target.”

At this time, another student raised his hand: "Then why did the murderer do this?"

Will was silent for a moment: "This is the topic we need to discuss in this class. Why did the murderer do this?!"

This time, there were no longer whispers in the audience, but exclamations.

"I know this sounds ridiculous, but it's not a random guess. The murderer was very particular about the order of brain cutting. He cut the prefrontal lobe first, which would bias the deceased's cognitive ability. He would not feel danger, nor would he feel any danger. Without the sense of self-preservation, the parietal lobe comes later, which is very important for the murderer.

And last is a small part of the temporal lobe. This part of the brain tissue manages some language abilities. The murderer retained it until the end. Does anyone know why? "

"Does he want to listen to this person?" one student said.

"Yes, talking to the dead all the time, and getting a sense of satisfaction that we can't understand.

The clothes on the deceased were very formal. They were worn when attending important occasions. On his body, the autopsy staff extracted a small amount of rosin powder. There was a little residual chestnut shavings in the gaps between the teeth, but the inside of the mouth was very clean, so I I am convinced that the murderer attached great importance to etiquette. He sat across from the deceased and even asked the deceased to rinse his mouth with lemon water after the meal.

After that, the murderer released the deceased and asked him to leave. However, at that time, the deceased was already in a state of cerebral palsy, so he just opened his brain and kept walking in one direction, and kept walking. After walking for a long time, he finally tripped over a pebble and lay down on the river bank. Mud splashed on his brain tissue, causing widespread infection."

As Will spoke, he seemed to gradually fall into some kind of sleepwalking state. He seemed to see himself walking aimlessly along the river bank.

"Then let me ask." A student suddenly interrupted Will's fantasy: "Why didn't the murderer just kill the deceased?"

"Why did he kill the deceased?" Will actually asked: "The murderer in this case was not a crime of passion, or a madman seeking some kind of material gain. He knew exactly what he was doing, and he cut open the deceased's body. Maybe it's because he feels that the doctor's brain is fuller than other people's brains due to long-term operation.

He regarded these as the necessities of a sparse and ordinary life. Instead of massacre, he even felt that for the deceased, it was a kind of spiritual sublimation, so he made the deceased dress so formally.

He believed that what he did was a gift and salvation to the victim.

Yes, if it weren't for him, how many people in this world could? "

Will said, lost in some thought.

(Stop arguing, Uncle Jigsaw will come out next. Are you all perverts arguing over a villain? Humph! ~Tsundere Face~)
