Yang Qiuchi smiled, but he didn't have the bottom in his heart, judging from the current situation, he didn't find any valuable traces, and the only hope was to see if he could find a little clue from this window in and out.

Yang Qiuchi asked Lei Zhutou and the others to go out, asked Nangong Xiong to bring in the physical evidence investigation box, closed the door, put on gloves, and first checked the remaining male and female swords, and no blood stains were found on the sword.

He took out the fingerprint brush from the physical evidence investigation box, carefully brushed it on the window inside and outside where there might be fingerprints, and found several fingerprints, which made him very excited and extracted them one by one.

Then, he brushed the male and female swords all over the place, extracted several fingerprints, and then measured the width and thickness of the sword.

Immediately, he took out a miniature digital camera to take pictures of the scene and traces, and then extracted blood stains from various places for examination.

Upon closer inspection, no other valuable evidence or traces were found.

Yang Qiuchi pushed open the door and came out, Wu Ciren greeted him, and asked nervously, "Lord Yang, have you found anything?" ”

Yang Qiuchi shook his head and said to Wu Ciren, the political envoy of Youbu: "Lord Wu, the junior brother wants to re-examine Ling Yan's body, I don't know if it's possible?" ”

"Okay, okay! That's as it should be. Wu Ciren said repeatedly, "The body of the little girl is now parked in the mourning hall, let's go." ”

Yang Qiuchi was slightly stunned and said, "It's not good to open the coffin in the mourning hall. ”

"That'...... So what to do? ”

"You find an excuse to pull up a tent, block the coffin, and carry the coffin to a separate room."

"Okay, how about reciting the scriptures?"

"Well, you can do anything, just don't let anyone else know about it as much as possible."

After a while, Wu Ciren hurriedly came back and said, "Sir, it's done, Sir, please." ”

Yang Qiuchi and the others followed Wu Ciren to a side room next to the mourning hall, where Miss Qiaozhen had not yet been buried, lying on a funeral board, covered with a white cloth.

Yang Qiuchi gently lifted the white cloth, revealing the white face of a young girl, lying there quietly, with her long black hair scattered and her eyes slightly closed, as if she had fallen asleep.

Yang Qiuchi sighed very emotionally in his heart, what a young life, the flower-like years, withered like this. Every time he performs an autopsy and meets a young girl, Yang Qiuchi always involuntarily rises with a feeling of emotion for life.

Wu Ciren and the others had already retreated, and only Yang Qiuchi and Song Yun'er were left in the wing.

Yang Qiuchi lightly asked Song Yun'er to help untie Miss Qiaozhen's dress. On the surface of the body, in the throat area, there was a narrow wound that was flat horizontally, which was the fatal wound mentioned by the previous post-mortem officer.

In other parts, there were no obvious scars, and according to the routine of forensic examination, the hymen was examined, and it was determined that Wu Qiaozhen was still a virgin.

Yang Qiuchi took out the probe and carefully inserted it into the wound in his throat, and involuntarily sighed.

Song Yun'er asked, "What's wrong?" Is there something wrong? ”

This wound punctured the trachea, pierced the spinal cord, and pierced the cerebellum, so Wu Qiaozhen died instantly, and there was no time to call for help, and the tracheal vocal cords were punctured, and there was no way to call for help. The murderer is ruthless, his shot is extremely vicious, and the stabbing part is accurate, and the blow is fatal. ”

Song Yun'er also frowned: "This murderer is not powerful." ”

"Yes, Wu Qiaozhen knows martial arts, but she was killed by the other party's move, which shows that the murderer is likely to be a professional killer." Yang Qiuchi said, pulling out the probe, "Yun'er, you judge the murder weapon." ”

Song Yun'er carefully observed the wound in the throat of the deceased, and said: "This wound has a double acute angle, the wound wall is smooth, and there is no bridge between tissues in the wound cavity, so it should be a double-edged sharp weapon." ”

"Very well, what do you think this sharp weapon will be? Dagger? Or a sword? ”

"It's hard to say, judging by the length of the wound you inserted with the probe just now, both are possible."

Yang Qiuchi nodded, inserted the probe into the wound cavity again, let go of his hand, pointed to the section of the probe that exposed the wound, and asked, "Yun'er, have you found any characteristics of this wound?" ”

Song Yun'er looked left and right, and sighed: "Strange, how did it stab into the throat obliquely from the bottom to the top?" It's a strange move. ”

"You know martial arts, tell me, why is this trick strange?"

Song Yun'er waved her hand and made a forward stabbing action: "Whenever the two of them make a move, they usually stab straight into the throat of the other party, judging from this wound, this move should be stabbed diagonally from the bottom of Wu Qiaozhen's front to the back and above - could it be that when the sword pierced, Wu Qiaozhen was leaning back to dodge, but failed to dodge?" ”

Yang Qiuchi's eyes lit up and nodded: "It makes sense, you continue to analyze." ”

After receiving Yang Qiuchi's approval, Song Yun'er was very proud, learned Yang Qiuchi's movements, touched her chin and groaned for a while, and said: "There is another possibility, this murderer is a child, or although he is Chengren but very short. ”

Yang Qiuchi nodded again: "Very good." Anything else? ”

Song Yun'er thought for a while: "Could it be that she committed suicide?" ”

Yang Qiuchi was slightly stunned, and said with a smile: "Tell me your reason." ”

"Look." Song Yun'er made a gesture of holding the dagger and stabbing it diagonally into her throat, and then made a gesture of sticking the sword diagonally upside down on the ground and hitting the tip of the sword with her head, "This is all right." ”

"Then why must it be suicide? Could it be that there was a sword stuck diagonally upside down on the ground like this, and she didn't pay attention to it and swooped forward, accidentally stabbing it into her throat? ”

Song Yun'er was stunned for a moment, and said to herself: "Yes, this is also possible." ”

Yang Qiuchi shook his head and smiled: "These possible surnames are very small, first, Wu Qiaozhen did not have any signs of suicide in advance, and there was no suicide note at the scene, and after understanding, there was no reason for her to commit suicide; Second, if you want to commit suicide, girls generally do not choose bloody self-killing, and often choose to hang beams; Third, even if you choose to kill yourself, if you use a sword, you will often wipe your neck and cut off the carotid artery, if you use a dagger, you will stab your heart, almost no one will stab your throat, and you will use this strange angle. ”

Song Yun'er nodded, and asked again, "What if she chose this weird posture to commit suicide?" ”

Yang Qiuchi said: "As I said just now, this wound pierces the spinal cord and pierces the cerebellum, and such an injury will cause instant death, so if it is a suicide or an accident that inadvertently bumps into the tip of a sword that is stuck obliquely on the ground, the murder weapon will generally remain in the wound, or at least in the palm of the suicide or on the ground, but no suicide weapon was found at the scene." This is sufficient to rule out that the deceased died by suicide or accident. ”

Song Yun'er had a look in her eyes that was almost admired, and she looked at Yang Qiuchi, making him a little embarrassed.

Yang Qiuchi continued: "Comprehensive analysis, the deceased Wu Qiaozhen should have been stabbed to death, the possible surname of the child or dwarf is too special, let's not consider it first, first analyze it according to the most likely situation, if it is Chengren, we analyzed it just now, he may have stabbed Wu Qiaozhen in the throat in the posture of Wu Qiaozhen's neck leaning back, and the other possibility is to stab Wu Qiaozhen from the bottom to the top with a sword in an upright state." ”

Song Yun'er thought for a while: "I think the first possibility is that the surname is relatively big, it should be a two-person move, the murderer made a move too fast, Wu Qiaozhen didn't have time to dodge, her head was tilted back, and she was stabbed in the throat." ”

Yang Qiuchi thought for a while, didn't speak, and repeatedly inserted the probe into the wound cavity of the deceased's throat, carefully observed it from front to back, left and right, and then shook his head: "No, the angle of the wound does not match the situation of being pierced when he tilted his head back to dodge." Yang Qiuchi took the probe and placed it next to his neck, then leaned back his neck, put one end of the probe in his throat and the other end in the cerebellum, and said, "Have you noticed?" Even if it is leaned back to the maximum angle, it will not be able to form the wound of the deceased. ”

Song Yun'er's eyes widened and she glared at Yang Qiuchi, still not quite understanding what he meant.

Yang Qiuchi simply flipped the body over and lay on its side, then inserted the probe, and began to slowly tilt the deceased's head back, tilting it at a slight angle, the probe in the front section was blocked by the end of the wound and began to stretch, Song Yun'er immediately understood, from the perspective of the blind tube channel formed by the piercing, the deceased was not pierced backwards, but the head and neck were almost pierced in an upright state.

In other words, the moment the deceased Wu Qiaozhen was killed, he should have stood face to face with the murderer, and the murderer suddenly stabbed Wu Qiaozhen to death.

Yang Qiuchi said: "There are no obvious traces of the fight at the scene, it is likely that the deceased was killed by surprise, and the murder scene was in the center of her bedroom, so the murderer should know the deceased, and it is likely that he is still very familiar, so he will be defenseless." ”

Song Yun'er was very happy: "So, the murderer is circled among the acquaintances of the deceased?" ”

"Yes, and it should be someone who can enter the deceased's room at will."

"And this person can also do martial arts, and his martial arts are very good!" Song Yun'er also made up a sentence.

Yang Qiuchi nodded: "Yes, this move used by this person is contrary to common sense, but I don't know what martial arts will make such a move?" ”

At this time, Song Yun'er's expression became solemn, she frowned and thought for a long time, and shook her head: "Brother, I don't know what sect of martial arts has this kind of trick that can pierce people's throats from such a strange angle. ”

The two thought about it, and suddenly their eyes lit up at the same time, they glanced at each other, and they both thought of someone at the same time - Liu Ruobing!

Yang Qiuchi said: "Yun'er, you go and invite your master to come and help you visit Xiang." ”

Song Yun'er nodded: "Hmm!" I'm afraid that only the master knows the origin of this trick. ”
