Chapter 049
The meeting room was very dark as a whole, because only one of the three light tubes was turned on, and the policeman in charge of taking minutes of the meeting was sitting directly below it.
Most of the rest of the light is shrouded around the projection screen, illuminating that piece of blue.
This kind of environment is very similar to a drowsy movie theater when playing literary films.However, as soon as Fang Yuan turned her head and saw the picture on the curtain, the drowsiness in her mind was immediately scared away.
Liu Xu's parents are locals, so they came quickly.Although devastated, they still happily signed the informed consent form for autopsy.
Now above the curtain, it is a diagram about this dissection.
Ning Yuan stood on one side, turning the laser pointer in his hand, and the red dot on it also turned around. The circled position was the chest of the deceased, and the blood stains were exposed after the clothes were removed and the surrounding area was cleaned. After coming out, it looked even more ferocious.
However, everyone present was already used to this, no one showed any discomfort, and everyone's gazes were all looking at the red dot.
"According to the results of the autopsy, this is the cause of catkin's death. The width of the entire wound is 1.5 centimeters, and the depth is 10 centimeters. After comparison, it can be confirmed that it is consistent with the fruit knife found at the scene."
Today is a formal meeting, so Ning Yuan also changed into his uniform.Inside is a light blue shirt, and outside is a white coat.
The white color is already clear and clear. When he spoke, his upper body also leaned forward. The blue light of the projector hit the white coat, and there was a faint blue part, making him appear a little mysterious.
Fang Yuan followed, unable to move her eyes away, it was hard to tell whether she was looking at the picture or Ning Yuan.
However, in this gap, Ning Yuan had already switched the laser pointer to the picture of a fruit knife, and marked it next to it, which clearly stated that it was 10 cm long, 1.5 cm wide, and single-edged.
The first room from the left on the fourth floor of the detachment building is dedicated to displaying tool samples. It lists some common crime tools, which can be roughly divided into two categories: sharp weapons and blunt weapons.
In every case, the forensic doctor will compare them one by one according to the state of the wounds. What's more, the tools were found from the scene of the crime this time, and they will be compared again during the autopsy, just to be safer.
Everyone knew this and nodded their heads in agreement.
This was especially true for Fang Yuan herself. She followed into the pathology laboratory in the afternoon, and had already seen the wound intuitively.Seeing the crime tool now, I have a concrete impression.She stared at the fruit knife and began to imagine the whole process of injuring someone when it was held by the suspect.Ning Yuan continued to talk, which happened to be connected with her train of thought.
"The fruit knife pierced his chest wall, pierced his heart, and caused a lot of blood loss. Before he fell to the ground, he subconsciously grabbed the murder weapon, so he left resist wounds on the fingers of his right hand, but the wound It is very shallow, from which it can be inferred that he has no strength to resist at this time. More importantly, because the blade of the murder weapon has sunk into most of it, and only a tiny part remains outside."
While talking, Ning Yuan used 3D software to demonstrate.
The distance from the chest wall to the heart is usually only 4-5 centimeters, but the length of the fruit knife is ten centimeters, which is more than enough to stab the heart directly.Fang Yuan closely followed his train of thought, and sure enough, she found that the same was shown on the video.
Even though she knew it was just a simulation, Fang Yuan still subconsciously touched the position of her heart.After a few seconds, he realized how stupid he was, and immediately put his hands away.
"Trauma of this degree is already serious, usually causing shock and even death within three to five minutes. But the murderer immediately pulled out the murder weapon, which undoubtedly accelerated the death process."
"The weapon had wounded the artery, and the blood would come out quickly and continuously."
As Ning Yuan said, he switched the PPT to the next page.What appeared in front of everyone at this time was the scene of the crime center—the three-dimensional panorama of the balcony.
The three-dimensional panorama is better than being intuitive and concrete. For a while, everyone was attracted and simulated images in their minds to restore the scene of the crime. Naturally, this is what Ning Yuan wanted to say.
"From this picture, the background board is right in front of the wall, on the right hand side of the chair. Since the distance between the three is very close, after the blood splatters, it will naturally splash on the background board and the wall. According to this , we can deduce the direction of movement of the two at that time."
"Obviously, the murderer stood up from the chair, turned around, and then stabbed Liu Xu. Liu Xu stood for a short time, and then fell to the ground quickly. On the chest of his clothes was the blood spurted out when he was injured, and then The back and even the shoulders were stained with pools of blood after falling to the ground."
The figure next to it is a strong support for these inferences.On the wall and the background board, there are curves composed of densely packed small dots, very similar to a parabola in mathematics.This shows the murderer waving the murder weapon.
As before, every time Ning Yuan explained, there were 3D images and pictures of the crime scene as evidence, but in the spirit of rigor, he still asked his brother to cooperate and do a scene reenactment.
This is Ning Yuan's habit, so it was not surprising that Ning Zhi was suddenly named, he walked towards the curtain, Ning Yuan stepped aside, and stood there calmly waiting for his brother to stab him.
Ning Zhi took off his coat and put it on for him, and walked straight towards Fang Yuan, "Come here."
The conference room was full, except for the three of them, there were also Xu Yang, Fang Ye, the forensic doctor of the DNA laboratory, and Lin Zang.Almost more than half of them knew about Ning Yuan's injuries before, and they understood Ning Zhi's avoidance now.
Fang Yuan naturally knew about it, but seeing Ning Zhi walking towards her, she still felt a little nervous.
Although Ning Zhi was really angry only once in the underground parking lot of the hospital, but he has always kept a cold face, and it can be said that he has a strong prestige...
"The only thing that needs to be met here is your height."
"?"
As soon as Ning Zhi opened his mouth, Fang Yuan was a little dazed subconsciously. After she reacted, she realized that Ning Zhi was revealing specific information, and hurriedly asked, "Is the murderer roughly 1.6 meters tall?"
"En." Ning Zhi nodded as a tacit consent, signaling her to follow the previous analysis.Fang Yuan blankly took the pen as the murder weapon, glanced at the curtain again, and then stabbed stiffly.
Since Ning Zhi is so sure, he should have some information.
So... was the murderer really a woman?
Although Fang Yuan followed suit, her head had already been let go. When she realized it, she saw Ning Zhi fall backwards, and Ning Yuan ran over to help him, thus avoiding the tragedy of falling.
Assuming that Wen Qing is really the murderer, how determined is she, a weak and weak girl, to leave such a clean wound, and then pull out the murder weapon quickly.
Anyone with common sense would know that pulling out the murder weapon at such a time would speed up death.The wound on Liu Xu's finger, and her behavior of throwing the murder weapon in the bathroom, proved that she intended to kill someone intentionally.
"Thank you, thank you for your hard work." Fang Yuan was still in a daze, but Ning Zhi helped her pull up the chair again. Although the other party was just out of politeness, Fang Yuan still felt a little flattered by his behavior.
Lin Zang was standing next to her, lowering his head and giggling when he saw her so busy.At this time, Ning Zhi had already walked away a few steps, and he didn't bother to come back to fix people.
Lin Zang is very active on weekdays, loves to make troubles and jokes.Fang Yuan knew how bad the other party was, so she had to lower her head to let her ears cool down naturally.
Fortunately, it's very dark here, so maybe others won't see it too clearly, so she can only think so.
Fang Yuan raised her head again, and found that Ning Yuan had returned to her original position, and the PPT page had switched to several close-ups.
"This is the rose tooth, and it is also a testimony to death due to massive blood loss. Except for those two wounds, the deceased did not have any trauma, and there was no fatal disease."
Ning Yuan's voice was full of exhaustion, but it could be heard that he was trying his best to refresh himself. Fang Yuan knew that he could no longer fly, so she hurriedly followed to watch the close-up.
The pink color is obvious, and it's nothing to look at the teeth on weekdays, but this kind of partial close-up is really too impactful.
Next to the teeth is a close-up of the contents of the stomach, also packed with impact.Fang Yuan just watched and felt that she was back at the scene of the autopsy.
The one on the far right on their side is the policeman from the police station, probably because he suddenly couldn't take it anymore, he hastily lowered his head in a concealed manner.Fang Yuan saw it, and couldn't help but think of how cowardly she was during the autopsy.
Ning Zhi stood up and handed water to the police officer, Fang Yuan met his eyes, and turned back quickly and obediently.
It is not known exactly what Liu Xu ate for his last meal before he died.
But during the autopsy, she saw lettuce and millet in the other's stomach.
The appearance of these two things is still relatively intact, most of them remain in the stomach, and only a small amount enters the duodenum.It can be inferred from this that he had only 1 to 2 hours to eat before he died.
Fang Yuan thought about it, and Ning Yuan also happened to say this, "His death time was around nine o'clock in the evening on April 4th, and his eating time was around seven to eight o'clock, which was about the same as the usual dinner time."
Afterwards, Ning Yuan cut the PPT again, on which was a close-up of the blood at the scene of the crime.
Regarding this point, Fang Yuan followed her to the simulated community on the third floor, and now she just glanced at it before recalling it.
At this time, Ning Yuan was also looking in this direction. Fang Yuan silently glanced around, feeling uneasy about being called up by the teacher to answer questions during class. She shook her head quickly, but Ning Yuan quickly turned her head away. , Picked up the laser pointer again.
The little red dot stopped on the side of the blood drop, but it was brighter and more vibrant.
Fang Yuan sighed a little, but looked at Ning Yuan over there with no expression on her face.He tapped on the blood drop one by one, followed by his own explanation.
"Here is the drop-shaped blood stain under the chair. The blood drop is round and there are obvious jagged edges around it. It can be inferred that the blood dripping object is only about 0.5 meters above the ground. The position under the chair cannot be the place where the deceased fell. It can only be inferred that the blood was stained on the fruit knife after the murderer drew the knife. She stood in place for a while, which caused the blood to drip. This is related to the death of the deceased The oval-shaped bloodstains caused by the movement are obviously different."
"But the murderer may have panicked and didn't notice the few drops of blood. Instead, he threw the murder weapon in the bathroom, and then took a rag to wipe the pool of blood next to the dead. This left wipe-like blood on the floor. Including In the sink, although the murderer washed his hands and arms with water, marks were inevitably left behind."
Ning Yuan clicked the next page while talking, this time it was a close-up of the balcony floor and the sink.
These two photos are all dark, but the middle position is highlighted with blue fluorescence.This is the phenomenon when the luminol reagent glows, which means that there is blood here.
The ground of the balcony was wiped and formed a large area, while the sink was dotted, which was caused by the murderer's blood splashing from his hands when washing his hands.
The luminol reagent is very bright when it reacts, and the light was deliberately turned off when shooting, so although the background is dark, at this moment, the entire curtain is full of blue.
Fang Yuan stared at it a few times, feeling a little uncomfortable.
According to Ning Yuan's remarks, it is almost possible to make a reasonable deduction of the time when the crime happened.
Although the murderer was flustered when he committed the crime for the first time, so that he left a lot of mistakes, but he did it neatly, which is not like what ordinary girls can do.
She herself has been watching Wen Qing's videos long ago, and often buys cosmetics, and she also chooses based on the other party's sharing of good things.After the incident, I used the Internet to do my best to understand it.
Therefore, at this moment, she really couldn't combine a lively and cheerful girl with this murderer.
In her imagination, there was only a black image of this murderer.
Some of her wanted it to become clearer, but she was also a little afraid.
Especially now...Wen Qing has not been traced until now.Running away?or something else?
What is the motive for the murder?
Or... In this rental house, there is another woman with a similar height to her?
Fang Yuan couldn't help thinking wildly, she could tell from her eyes that she had already been released to other places.
When Ning Yuan passed by the senior sister from the DNA laboratory and returned to his seat, he happened to see her like this and hurriedly poked her shoulder lightly.
"I'm going to talk about the results of the biological tests soon, so listen carefully."
The author has something to say: That's it, I really can't finish writing today, and I will make up for the bad day tomorrow.
