Schiller returned to the room, he didn't touch the windowsill with his hands, but just gestured to Gordon with his eyes, Gordon stepped forward, glanced at the windowsill and said, "The sanitary conditions in Wayne's Hospital are good, but this is just an ordinary ward, and the windowsill is a little too clean, right?" ”

Schiller nodded, and Gordon came closer, and he also stuck his head out to look down, and saw that the awning downstairs had a skeleton, and although the skeleton was wood, the wood was nailed to the wall.

Obviously, the awning was built during the construction of the building, and any build quality of Wayne Group is very good, so even if it is just an awning, it can also bear the weight of an adult male.

Gordon recalled the process he had just seen, and then, suddenly realized, "I know why there is no wound on the arm, Dr. Richard's arm, which was clutching the handle of the window, has not yet been withdrawn, and when the dagger is plunged into his heart, it is not that he does not want to resist, but he does not have time at all." ”

Schiller nodded and said, "Detective, you can look at his wounds again, especially the edges of the wounds, and you should find something different." ”

Hearing this, Gordon immediately walked to the corpse, half-knelt down, put on gloves, carefully examined the wound, frowned, and said: "The edge of the upper part of the wound seems to be a little different, but I am not very proficient in forensic science......"

"You don't have to be proficient in forensic science, have you noticed that the edge of the upper half is cut deeper than the bottom half, and guess why?"

While Gordon was still thinking, Bruce spoke.

"In order not to let too much blood drip on the windowsill, when the deceased faced the window, the murderer did not pull out the murder weapon, but only pulled out the murder weapon after turning the deceased around."

"But at that time, the murderer was standing outside the window, and the body had already slipped under the windowsill, and the murderer had to poke his upper body into the room, put his hand over the corpse's shoulder, and then pull out the murder weapon."

"When the murder weapon is pulled out, the force is applied above and behind the body, not directly in front of it, so it will cause the upper edge of the wound to be more severe."

Gordon shook his head and said, "How the hell did you deduce so much in such a short period of time?" ”

Schiller did not come in, but stood outside the window, looked down at the windowsill, and said, "Next, we can talk about the personality of the murderer." ”

"You also deduced the personality of the murderer?!!" Gordon asked, raising his voice.

"After his series of actions, I think you should see that this is a deliberate murder, and the murderer has been prepared for it, maybe he has rehearsed it countless times."

"In this case, he didn't pull out the murder weapon at the first time, and the movement of turning the body was fast enough, the blood may not have dripped on the windowsill, but he still wiped the windowsill inside and out."

Schiller gently touched the window frame outside the staircase, looked at Bruce and said, "If the patient hadn't come back soon, you would have had a free window cleaner." ”

Gordon touched the side of his cheek and said, "What does that mean?" Does he have a habit of cleanliness? ”

"It shows that he is not confident enough." Schiller shook his head and said, "It also shows that he is actually a novice, and it is even very likely that he is committing a crime for the first time." ”

"Why?" Gordon asked. His thinking is actually fast enough, so he can figure out this case with some skills in such a short period of time.

But now Gordon is not very good at figuring out the psychology of criminals, because most of the cases in Gotham are gangsters or vendettas, and there is nothing to understand.

"Detective Gordon, do the theoretical knowledge you learned at the police academy be applicable in reality?" Schiller asked. ”

Gordon thought about it for a while, and then said: "Regarding criminal investigation, there are still many that are applicable, but in terms of civil mediation, it is almost completely inapplicable, and can only be adapted to local conditions. ”

"So, when you left the police academy, did you realize the difference between theory and reality?" Schiller asked again.

"At that time, I was still relatively simple, and I felt that since my grades were good, my practice should also be good." Gordon thought for a moment and said, "I did doubt it, though, but it's actually common sense, right?" Ordinary people know that theory cannot be 100% the same as practice. ”

"This is precisely the contradiction of this murderer." Schiller tapped the window frame lightly with the side of his finger and said: "Murder is a violation of morality and law in itself, and creating such a deliberate murder case with a deceptive nature, from investigation, to making a plan, to starting to practice, will definitely go through a longer process than killing with passion." ”

Gordon nodded, feeling that what Schiller said made sense, that killing people with passion is nothing more than a momentary rush, and when driven by anger, it is difficult to think of law and morality.

But this kind of deliberate crime will take several months to step on the point, but if the murderer has the slightest struggle, he will not be able to hold on for so long and put this plan into practice.

In ordinary premeditated murder cases, the murderer will try to cover up the truth in order to escape responsibility, but to do so interlocking without any mistakes, obviously, it takes practice.

"It's not a practice of memorization or a practice of dancing, every time the corrective action is corrected, the murderer will think that this is killing someone, and it is impossible for any normal person to endure such a great moral pressure." Schiller concluded.

Gordon's face became more and more serious, and he had to admit that what Schiller said was right.

In fact, he could see that the movement that Schiller had flipped just now was not very skillful, and besides, one hand was too strong, and if a knife was really stuck in Bruce's chest, blood might have splashed on the window frame.

And in the gap of the window frame on the side, there is no trace of blood, which means that the murderer did this action perfectly, and this undoubtedly needs to be practiced, and every time he practices, wouldn't he think that what he is holding in his arms will be a corpse?

Not to mention morality, but anyone who has a little bit of human nature will feel rejection, disgust and fear of it, this is human instinct, but the murderer is still resolute and practiced this action to perfection.

"A terrible man so cold, heartless." Gordon lamented, and Schiller immediately picked him up and said, "Or, let's call them 'born murderers.'" ”

As Schiller spat out the last few words, Bruce glanced at him, but said nothing, and Schiller continued.

"The most characteristic of this group of people is that they are cold-blooded, they do not grieve the loss of life, they take pleasure in hurting and controlling others, and indulge in the pleasure of wantonly depriving their fellow human beings."

"Not only do they not feel guilty and scared in the process of practicing a certain part of the murder in preparation for the murder, but on the contrary, the assumption of taking the life of others will provide them with a great deal of pleasure."

Gordon gave a cold war, as if he couldn't accept that there were still such human beings in this world.

Suddenly, Schiller changed his tone and said: "And I said that he was not confident, and it was exactly that, he had practiced so many times, but he still did not believe that his perfect movements would not leave any trace on the windowsill." ”

"Generally speaking, the biggest basis for judging the degree of perversion of a natural homicidal maniac is his arrogance, and the more arrogant and narcissistic he is, the more arrogant and confident he is in his own evil behavior, and the more arrogant and confident he is that no one can understand, the more difficult it is for him to deal with."

"I see." Gordon thought for a moment and said: "Therefore, some serial murderers like to return to the scene and watch the police being deceived by them, just because they are confident that they will not be discovered." ”

Schiller shook his head and said, "All the murderers who returned to the scene were not confident. ”

Gordon's eyes widened, Schiller's view is contrary to the current mainstream view, and the criminal investigation community still believes that the murderer of the serial murder case returned to the scene to tease the police.

"They will come back to the scene, in fact, they are not confident enough in their modus operandi, as long as they make sure that they have not left any additional clues, like a student who answers a test because he is worried about his score."

"In other words, as long as they do this, it proves that their methods are flawed, just like knowing that they are right, all the top students will not answer correctly, and those who don't know right or wrong are bottomless in their hearts."

Gordon squinted at Schiller, and he seemed to wonder why the professor described such a murderous murder as a daily exam, and although the metaphor was apt, the tone of understatement was creepy.

Schiller smiled a little, a little cold and neurotic, and whenever he showed this smile, even Bruce wouldn't meet his eyes.

Schiller lightly touched the windowsill with the tip of his index finger and said: "This murderer seems to be a bad student who is not confident in his answer, and has made up dozens of more processes, and wants to make up for it with quantity." ”

Schiller's face showed a hint of disgust, and then he said: "Only mediocre people would want to use exhaustive methods to commit crimes." ”

Then, Schiller restrained his expression, looked at Gordon, and said: "Fortunately, he is the kind of murderer who is not confident, so as long as you squat here, you should still be able to see him." ”

Gordon was about to go out, but Bruce stopped him, saying, "You can't be outside the door of the ward, otherwise, everyone knows that the police are here, you first take someone to pretend to survey the environment in the hospital, and I will be responsible for keeping an eye on here." ”

"You don't want to install a monitor, do you?" Schiller confronted Bruce for the first time today, and Bruce shook his head, saying, "No matter how bold the murderer is, he will never step into this room again, and I am going to set up a defense on this entire floor." ”

"He's probably a little bolder than you think." Schiller suddenly sneered, and then said: "I forgot to say, there is another kind of student, although he is not confident in his answers, but he is very confident in his ranking, and he doubts that he is not good in the exam, but he is even more suspicious that the questions in this exam are difficult, and everyone is not good in the exam." ”

"So......" Bruce narrowed his eyes slowly.

Just then, there was a cacophony outside the window, Bruce rushed to the window, Schiller turned sideways, Bruce heard, and a riot broke out downstairs.

As both Gordon and Bruce rushed out the door, they heard Schiller whisper:

"Perhaps, he didn't want to come back, but didn't leave at all?"

Just as Schiller was returning to the ward, he heard the screams of the head nurse coming from the ward downstairs.

"Hallie! Little Hallie!! What happened to you?! Why do you have so much blood on you?!!! ”

Look at the details, look at the details, friends!

Don't give me a chance to call you little fools!
