Yun Yeyao said: "Gu Wu's body leaned against the screen in an abnormal posture, and Xiao Zuo proposed at that time that according to the location of Gu Wu's wound, the prisoner could only attack him from behind, but from behind, it was absolutely impossible for the victim to die by sitting in front of the screen." ”

"So there must be something strange here, Xiao Meng, come and see." Yun Yeyao pulled Xie Yunmeng around the back of the screen, pointed to the place where Gu Wu's body fell, and said: "After the victim's blood flowed to the partition line between the oil painting and the base of the screen, it was cut off, indicating that the screen was open at that time, just like we did just now." ”

At the same time, it proves that when the murderer killed, he was not standing behind Gu Wu, but on the front of the screen. Gu Wu's position at the time of his death was behind the screen, and it is possible that the murderer had been hiding somewhere in the room, watching Gu Wu walk behind the screen, and then secretly open the screen and kill him. ”

"This must be a murderer with a lot of strength, I think it may be the same person who attacked the airport guard, Xiao Meng, you checked the wound on the head of the airport guard, and the skull was shattered with one blow, you also thought at the time that the suspect had a lot of strength, right?"

"Hmm." Xie Yunmeng responded simply, listening intently to Yun Yeyao's analysis.

"The opening direction of the screen is to turn up from the bottom to the top, maybe the thing that hit Gu Wu's head is not a stick at all, it is precisely this screen, the murderer lifted it, if Gu Wu looks down at the ground, won't the back of the drawing board hit him diagonally above the back of his head?"

"The murderer only needs to take advantage of Gu Wu's inattention, use enough strength, and quickly lift the upper part of the screen, and when the goal is achieved, he will let go of the screen again, let the drawing board return to its original position, and catch the fallen Gu Wu."

Xie Yunmeng questioned: "Xiao Yao, in this case, the blood stains on the back of the screen that coincide with Gu Wu's head should be at a higher place, and besides, after the murderer puts down the screen, how can he stab the knife into Gu Wu's back?" What does this have to do with the villa underground passage you mentioned? ”

It was another series of questions, Yun Yeyao seemed to be confident this time, and immediately answered them one by one to Xie Yunmeng.

He said: "Because before being hit by the screen, Gu Wu had already been assassinated. Xiao Meng, let's analyze it little by little, you see, the blood stains on the back of this screen, the one left by the impact of the head is very large, there are blood spots splashed out all around, and there are broken bones, and if you touch it carefully, there are still cracks on the screen plate that is soaked in blood, which proves that the possibility of hitting directly with the screen is very high. ”

"Gu Wu was beaten and collapsed backwards, the murderer can have several options, first, he can use his body to resist the screen, and with the inertia of Gu Wu's fall, he will kill him with a knife, and then put down the screen."

"The disadvantage of this is that the blood spilled after pulling out the cleaver will be spilled everywhere, including the murderer himself and the surface of the base of the screen, but the blood stains on the back of the screen are obviously flowing straight down after the head is hit, and there are no traces of large-scale splashing at all, so the above guess is incorrect."

"Secondly, the screen is not very thick, as long as the murderer has enough strength, or with the help of some tools, he can put down the screen, find the right position, pierce the knife from the front of the screen, pierce Gu Wu's heart, and then pull it out, it takes a certain amount of time to do this, we temporarily think that the murderer did have enough time to kill at that time, and the surface of the screen is covered with drawing paper, we can also think that the confetti in Gu Wu's wound comes from the broken drawing paper."

But this speculation is not true, Xiao Zuo has examined the confetti left in the wound, all of which come from some white paper, the thickness is about the same as that of printing paper, not drawing paper, and there are no traces of painting on it. Then there is the screen, there is no trace of damage, Xiaomeng thinks, even if the murderer has enough time to commit the crime, it is impossible to have time to repair the screen. ”

"Gu Wu's death time is only a few hours longer than Shen Muyan's, if it is the same murderer, then he almost killed Gu Wu, and immediately went to Wang Haicheng's house to kill Shen Muyan, so the possibility of staying to clean up the scene is very small."

"So it's not the same murderer?" Xie Yunmeng asked.

"That's too late! Fixing a sketchboard to make it exactly the way it was before is difficult, and it's not a task that can be done in a few hours. ”

"But the murderer just replaced it with a new piece of drawing paper and covered up the broken place?"

"Xiaomeng, don't interrupt, listen to me!" Yun Yeyao was a little annoyed, slapped Xie Yunmeng, and said, "Can the light cover the hole, can it escape the eyes of the police?" ”

"I'm not interrupting, I'm just questioning the possibilities." Xie Yunmeng reached out and touched the surface of the screen with a somewhat mocking tone, as if he still couldn't fully believe Yun Yeyao's reasoning.

He usually doesn't do this, so after being annoyed, Yun Yeyao immediately began to pay attention to his movements, and also reached out and touched the same position, and then looked at Xie Yunmeng.

There were no questions or answers, the two tacitly knew that Yun Yeyao already knew what Xie Yunmeng wanted to hint at.

In that picture, a small bird is pecking grass seeds with its head down, and under the bird's beak, Gu Wu's manuscript paper is being placed.

Xie Yunmeng pretended not to pay attention to Yun Yeyao, and turned his head to carefully look at the blood stains behind the screen.

The manuscript paper was obviously deliberately moved, looking at Xie Yunmeng's appearance, Yun Yeyao must have done it, and he must have studied the imprints on the manuscript paper.

Yun Yeyao picked up the above sheets and found that these marks had been re-deepened with a pen that could not write words, and the bending degree of the upper manuscript paper was not the same as that below, and it was obvious that they had been taken away and then put back.

He rolled up the manuscript paper and put it in his pocket, and said to Xie Yunmeng, "Thank you." ”

"Huh, what are you thankful for? I don't know anything, even if my father-in-law asks in the future, you are not allowed to rely on me, I am a person who keeps promises. ”

"Thank you for taking my right to know."

Xie Yunmeng suddenly turned around and put his forehead against Yun Yeyao's forehead, and said: "Don't talk to me in such an official language, I don't know the truth, and I don't want you to be sad, no matter what the result is, as long as I can help, I will definitely do it, and you and Xiao Zuo can't just think about the problem according to their own ideas, you know?" ”

"Hmm." Of course, Yun Yeyao understood what his lover meant, he nodded obediently, then looked up with a smile and kissed Mr. Criminal Police, and said, "Although you gave Xiao Zuo a hint and gave me a hint, but, you are helping your father in your heart, right?" I won't ask my father what he told you, but I don't think my father would have opened his mouth until he had to. Xiao Meng, you know that only I can keep up with Xiao Zuo's pace, so you want me to help my father at a critical moment and reduce Xiao Zuo's hatred for him, right? ”

"You'll be in touch, okay, now let's move on to the homicide reasoning." Xie Yunmeng scratched the tip of Mr. Actor's nose, let go of him, and signaled that it was time to get down to business.

Yun Yeyao said: "In addition to the above speculation, the last one is that the murderer assassinated Gu Wu first, and then hit him on the head with a screen. Suppose that the murderer killed Gu Wu somewhere else, moved him to sit behind the screen, then broke the wine barrel, spilled the wine and debris everywhere, and then went around the front of the screen and hit the victim on the head. ”

As soon as Yun Yeyao's analysis came out, Xie Yunmeng shook his head, he said: "Impossible, even if a dead person sits on the ground, his body is soft, and he will collapse at any time, and the screen hitting his head will not cause very serious injuries, and Forensic Medicine Mo said that the two acts of hitting the head and stabbing in the back should be completed in the same time period." So your guess doesn't hold up. ”

"Yes, Xiao Meng, there are many fragments of the wine barrel on the ground that are pressed under Gu Wu's body, if the murderer moves his body to the place of death and then breaks the wine barrel, there will not be so many fragments under the corpse, and it is impossible not to leave the murderer's footprints on the wine."

"Therefore, the only possibility is that Gu Wu was drinking behind the screen, and the murderer suddenly came out of somewhere, directly assassinated him, and before Gu Wu's body could react, he quickly raised the screen and hit him on the head, and then let him lean against the back of the screen, and he disappeared from where he came from."

"Why is the screen placed in the center of the room? Ordinary families don't design it this way, and besides, this screen wall is connected to the floor, and it is still on the second floor of the villa, how can there be an underground passage? Xiaomeng, can you figure out the key to this? Yun Yeyao asked, her eyes flickering as she looked at Xie Yunmeng.

Xie Yunmeng squatted down, reached out and knocked on the floor next to the base of the screen, making a dull sound, he imagined the relative furnishings downstairs in his mind, and after a while, he said: "It's the stairwell, Xiao Yao, you wait, I'll go to the stairwell below to check." ”

After speaking, Xie Yunmeng went straight to the bottom of the stairs, and when he disappeared at the bend of the stairs, Yun Yeyao looked under the screen, showed a wicked smile, and said softly: "You can't hide, do you know why Xiao Zuo found out where you were hiding, but didn't say it?" Because what he said at the time was tantamount to falling into your trap. ”

"What's going on with those papers? Do you want to use my father's past to attract the attention of the police and play the emotional card? Or do you want to use the story of Xiao Zuo and me to hint at your own fate? I've read these manuscripts a long time ago, before Xiao Meng, until now, I've been pretending to be stupid, just for your broken plan, I'm so sorry if you don't show up, Xiao Meng and Xiao Zuo will also be angry, come out, let me and Xiao Meng take a good look at your true face. ”

While Mr. Actor was speaking, his footsteps went around the screen and stood still, looking at the floor where Gu Wu's body was sitting, slowly, the floor began to lift upward, and a black head gradually emerged from below, and vaguely, he could see that there was a handful of things shining with cold light in his hand.
