"Uh......"

Suddenly, hearing Gao Yuan's direct use of an adjective like "completely", which meant that he completely denied his conjecture, Officer Twilight couldn't help but be stunned for a while, a little at a loss.

But soon, when Officer Twilight came back to his senses, he sighed helplessly, and had to ask:

"So what do you think is going on? Wise brother? ”

"If the murderer escaped through the window, then the top of that window must be too clean, right?"

Indifferent, Takato explained:

"Judging from the situation at the scene, the deceased's blood stains were sprayed into the toilet from the position of the door. In this case, the murderer, who was also in the toilet at the time, wanted to pull out the dagger that was stabbed on the deceased's body, and his body would inevitably be stained with the blood splattered on his body. In this way, if the murderer with blood stains on his body were to escape through the window, it would be impossible to leave no traces on the way. ”

As he spoke, Gao Yuan walked to the door of the toilet and looked inside-

"And more importantly, the blood splattered wasn't right."

Seriously, looking at the traces of bloodstains, Gao Yuan said very firmly.

"What's wrong?"

With a blank expression, Officer Twilight was a little unable to understand what Gao Yuan meant.

"The splattery of blood was supposed to be the moment when the dagger that was stabbed in the heart of the deceased was pulled out, and as the knife that blocked the wound was pulled out, the blood in the body splattered radially from the wound due to the pressure. And based on the traces of this splattered bloodstain, it is possible to determine the location of the deceased at that time. ”

Gao Yuan explained, and then pointed to the division of the blood stains on the floor and the walls in the toilet room, and continued:

"Judging from the bloodstains at the scene, the location of the deceased's wounds at that time should be here ......"

Walking to the door of the toilet, he pointed to the outline of the deceased who had been circled with white wire on the ground at this moment, and explained:

"Whether it's height or location, the center of the splash point is exactly where the deceased's heart was when it was found. In other words, the deceased was pulled out of the dagger inserted in her heart while lying on her side on the ground with her back against the toilet door. ”

As he spoke, Gao Yuan looked at the police officer of the forensic department on the side and confirmed the police's judgment on this matter.

In this regard, the police officer of the Forensic Identification Division couldn't help but nod his head, affirmed Takato's statement, and reported to Officer Twilight, explaining the preliminary investigation results of the Forensic Identification Section's investigation of the scene, which was consistent with Takato's judgment in this regard.

"This ...... What's the problem? ”

As for the current situation, Officer Twilight asked even more puzzled.

"Then what posture do you think the murderer should have to pull out the dagger from the dead lying on the ground?"

Gao Yuan asked Officer Twilight about this.

Hearing this, Officer Twilight looked helpless, and didn't seem to think that this was a problem, so he walked to the location where the corpse was now, and squatted down and said:

"What's the problem...... Just ......"

As he spoke, Officer Twilight made a demonstration, making a process that simulated a murderer reaching out and drawing a knife.

However, at this moment, Officer Twilight, who had just stretched out his hand, was stunned-

"That's right...... If the murderer had crouched down and pulled out the dagger, the murderer's body would have been blocked in the path of the blood splatter, so that the blood splatters at the scene should have left traces of being blocked. But apparently, the bloodstains at the scene showed no signs of being blocked. ”

Officer Gao Yuanjian seemed to realize the problem and opened his mouth to explain.

"That'...... Wise brother, what the hell is going on! ”

Seeing that Gao Yuan had thought about it so much, Officer Twilight, who originally thought that this was just a robbery and murder, only felt that he couldn't understand what was going on at all.

In this regard, Gao Yuan did not say anything, but asked the police officers of the forensic department to bring the murder weapon at the scene.

So, with the nod of Officer Twilight, the officers of the forensic department handed over the dagger that had been loaded into the façade of the evidence bag to Gao Yuan's hand along with the evidence bag.

After getting the evidence bag, Gao Yuan looked at the bottom of the dagger blade, and near the end of the gauntlet, there was a small circle of places that were obviously not stained with blood, but further back, there were still traces of blood staining on the gauntlet and the part of the grip.

Seeing this, Gao Yuan sighed in his heart-

"Now, the clues are all together."

So, Gao Yuan continued:

"Look, Officer Twilight. The dagger used as a murder weapon has a circle of unblemished parts at the bottom of the blade. ”

"Huh? Let me see! ”

Hearing Gao Yuan say this, Officer Twilight was suddenly startled, stepped forward and looked carefully at the dagger as the murder weapon, and then sure enough, as Gao Yuan said, there was a small circle of unstained parts on it.

"Huh? What the hell is the part that doesn't get bloody......"

Even more puzzling, Officer Twilight's mind was full of doubts.

"Don't you understand, Officer Twilight?"

At this point, Gao Yuan couldn't help but say:

"It's a rope. The killer tied a rope to that part of the murder weapon before stabbing the deceased to death with it. And afterwards, as long as you pull the rope from a distance, you can avoid blood stains on the murderer. ”

"Ahh That's right! ”

Hearing this, Officer Twilight suddenly realized:

"In this way, it can explain why the blood stains at the scene were like that, and it can also explain that there were no blood stains on the murderer......"

As he spoke, Officer Twilight was suddenly stunned, and said with a puzzled face:

"But in this way, wouldn't the murderer be able to escape through the window perfectly without leaving a trace?"

"However, there is blood on the spot just above the toilet door."

Gao Yuan further explained.

"Ah, this. I also noticed it when I was taking photos of the scene. ”

In this way, hearing Gao Yuan mention this, the police officer of the forensic department at the shooting scene couldn't help but explain.

"Huh? Then why didn't you report it to me right away? ”

Officer Twilight saw the clues mentioned by Gao Yuan, but he didn't know about it, so he couldn't help but say to the police officer of the forensic department a little angrily.

And in this regard, all the clues and it, Gao Yuan is sure that the current incident is the method in the original work-

"Obviously, there shouldn't be blood on it. But since there are blood stains, it can only mean that something with blood stains has passed through it. ”

Gao Yuan explained.

"Is it ......?"

Hearing this, Officer Twilight was suddenly shocked.

"The murderer didn't come in from the outside at all! If the murderer was an outsider and left through the window, there was absolutely no chance that the blood would have gotten on the top of the toilet door. Therefore, the murderer can only be the person in the store. ”

Gao Yuan explained:

And if the murderer had tied a rope to the murder weapon in advance to prevent blood stains from contaminating himself, then even if the murderer killed the deceased in the toilet, he would not have blood stains in that place if he tried to climb over the top. Therefore, there is only one possibility that this situation will be caused -

"The killer stabbed the deceased to death outside the toilet and then threw the body into the toilet, allowing the body to block the toilet door, giving the impression that the incident had taken place inside the toilet.

"And I, I already have a rough idea of who the murderer is!"

It's completely a copy of the reasoning of the original answers, and the details of all parties have been verified correctly, but the only problem is -

The deviation of this incident is not in the event itself, but in the timing of the event......
