At the end of the sentence, Aqiang still seemed to be frightened, with a look of panic on his face.
Gu Chen previously thought that the evidence in this case was conclusive, but now it seems that He Liqiang and Huang Zhiqiang's statements are based on their own opinions.
Moreover, even if He Liqiang was the murderer, would the murderer be stupid enough to come to the hospital for treatment after committing the crime?
At the very least, you have to hide and find a small clinic for treatment.
But this is a truth that ordinary people understand, so how could He Liqiang not understand it?
Moreover, He Liqiang was also covered in scars at this moment. Compared with the scars on Huang Zhiqiang's body, He Liqiang's wounds were mostly stab wounds, and there were cuts in many parts.
It is conceivable that if Huang Zhiqiang had been more ruthless, He Liqiang could have almost received the box lunch.
"He Liqiang." Gu Chen pointed at He Liqiang in front of him and said involuntarily: "You said Huang Zhiqiang killed his wife. What do you think the motive is?"
"What else could it be?" He Liqiang took a deep breath and said with fear:
"It's not because he found out about my affair with his wife."
"As for how you found out? I'm not sure. Originally, I went there today just to make it clear to his wife, Zhang Xia, so that she wouldn't look for me again in the future. It's as simple as that."
"But I don't know why? Why did he know it in advance? And he killed his wife."
"We will investigate this clearly. Now, you have to go back to the police station with us." Lu Weiwei said.
"Yes, of course. As long as you don't run into that lunatic, you can go anywhere." After He Liqiang finished speaking, he took a deep breath.
It seems that he has not recovered from the previous cruel state.
After taking He Liqiang back to the police station, Huang Zhiqiang was also brought back by Ding Liang and Huang Zunlong.
He Liqiang was in interrogation room No. 1, writing his story, while Huang Zhiqiang was in interrogation room No. 2.
Since the two people's confessions have completely opposite versions, it is difficult for Gu Chen to judge now, which of the two is lying?
Just in the corridor outside the interrogation room, Gu Chen's cell phone suddenly rang.
When he saw that it was Gao Chuanfeng from the Technical Section of the Municipal Bureau, Gu Chen immediately opened the answer button: "Gao Chuanfeng."
"Gu Chen, after our preliminary inspection of the body you sent over, it was found that it was hit on the head with a wooden stick and died."
"Especially the skull of the deceased was smashed by wooden sticks. We found fragments of wooden sticks on the head of the deceased."
"Moreover, we also found the bloody stick at the scene, which was confirmed to be the murder weapon."
"Knocked to death with a wooden stick?" Hearing such an answer, this was also in line with Gu Chen's previous judgment.
Gu Chen nodded slightly and asked Gao Chuanfeng: "Besides that, have you noticed any other abnormalities?"
"Not yet. I'm only responsible for the body examination. Besides, haven't you already gone to track down the murderer? How about it? Has the murderer been found?"
On the other end of the phone, Gao Chuanfeng also asked curiously.
Gu Chen echoed: "The murderer has been captured and taken to the interrogation room of our Furong branch."
"But now there is a thorny issue. The murderer and the deceased's husband both accuse the other of killing the deceased Zhang Xia."
"Moreover, the two people's statements are completely opposite. We now need to re-investigate the cause of death and the specific murderer."
After a pause, Gu Chen said again: "So, Gao Chuanfeng, if you find anything over there, remember to inform me as soon as possible."
"No problem, leave this to me."
The two also communicated briefly for a while, and then they both hung up the phone.
"How's it going?" Seeing Gu Chen put down his phone, Lu Weiwei also came over and asked.
Gu Chen shook his head: "Gao Chuanfeng only restored the time of death of the deceased Zhang Xia. It was the skull that was smashed with a wooden stick. But, was the murderer her husband Huang Zhiqiang? Or was it that He Liqiang? Now, we still have to
It’s hard to judge.”
After thinking about it, Gu Chen asked Lu Weiwei again: "By the way, what did those two people say?"
"What else can I say?" Lu Weiwei took a heavy breath and said in a bad mood:
"The two of them still insisted on their own opinions. They both said that the other party killed Zhang Xia."
"If it is said that these two people have the motive to kill Zhang Xia, then the circumstances that these two people have spoken before may be false."
With her back against the guardrail, Lu Weiwei also gestured and said: "Junior Brother Gu, look, there is an improper relationship between He Liqiang and Zhang Xia."
"And He Liqiang himself said that he wanted to go to Zhang Xia's house today to speak clearly to her, but he happened to bump into Huang Zhiqiang at home, and the two started fighting. This was a bit strange."
"First of all, is it really such a coincidence? It happened to be today. He Liqiang felt his conscience and wanted to go over and explain it clearly to Zhang Xia."
"If something happened, wouldn't He Liqiang explain it clearly to Zhang Xia on the phone? But he had to go to Zhang Xia's house? This is very confusing."
"Also, even if Huang Zhiqiang discovers that his wife Zhang Xia is having an affair with He Liqiang, will he kill someone?"
"Isn't it impossible?" Officer Wang on the side came over and said:
"Some people, once stimulated, can do anything."
"What's more, this He Liqiang is still a very good friend of mine. I can't stand it when my friend cheats on me."
"I think Huang Zhiqiang must have completely lost his mind at this time, and it is entirely possible to kill Zhang Xia and He Liqiang."
"Yes, I also think what Senior Brother Wang said makes sense. After all, impulse is the devil. In fact, many cases occur because the parties involved lost their minds and acted impulsively, which led to the occurrence of the case."
"So, after Huang Zhiqiang learned that his wife and friends were together behind his back, he must have been furious."
"If anyone has more motive for killing, I think it should be Huang Zhiqiang."
"After all, if you think about it, He Liqiang himself is in the wrong. Why would he kill Zhang Xia, who had an affair with him? What good would it do to him? The motive for killing is not strong." Yuan Shasha also shared her thoughts with everyone.
come out.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Gu Chen shook his head: "Although what Xiao Yuan said makes sense, it is also in line with normal logic."
"However, some things cannot be explained by this normal logic."
After a pause, Gu Chen looked around and said, "This He Liqiang doesn't seem to have much motive for murder, but who knows if there are any other secrets between him and Zhang Xia?"
"As for He Liqiang, is it possible that He Liqiang wants to kill Zhang Xia because Zhang Xia has some information about him? If we don't investigate these things in depth, they may no longer exist."
"So, Huang Zhiqiang is more likely to have a motive for the murder, but that doesn't mean He Liqiang has no motive."
"Yes." Listening to Gu Chen's words, Lu Weiwei nodded silently and couldn't help but say:
"Now these two people are arguing that the father-in-law is right and the wife is right. Huang Zhiqiang insists that it was He Liqiang who killed his wife Zhang Xia."
"And He Liqiang insisted that it was Huang Zhiqiang who killed his wife Zhang Xia."
"But in Huang Zhiqiang's words, he was a victim from beginning to end. He said that after entering the house, he found He Liqiang staying at home, and then attacked him."
"And He Liqiang's statement was also very similar. As soon as he entered the door, he discovered that Huang Zhiqiang was going to kill him."
"Furthermore, He Liqiang also said that he and Zhang Xia actually had an improper male-female relationship, but are there any nepotistic interests between the two? We have not investigated this."
"If He Liqiang went to Zhang Xia's house this time, it was not to draw a clear line between him and Zhang Xia, but because of some conflicts, he wanted to make it clear to Zhang Xia."
"As a result, he accidentally killed Zhang Xia, or he took the initiative to kill Zhang Xia. At this time, he happened to meet Huang Zhiqiang who was returning home. The two of them started to fight again. After he escaped, he pretended to be a victim. This is entirely possible."
"Uh." After listening to Lu Weiwei's explanation, Yuan Shasha was stunned for a few seconds, and then analyzed and said:
"If you follow Senior Sister Lu's analysis, it is correct. If He Liqiang is really the murderer, then this guy is too scary."
"If you think about it, he killed Zhang Xia and then got into a fight with Huang Zhiqiang. Both sides suffered losses."
"But after He Liqiang escaped from the room, he did not choose to hide, but openly ran to the hospital for treatment."
With a faint sigh and trying to calm down, Yuan Shasha couldn't help but say: "This kind of courage is probably not something ordinary murderers can achieve. It requires a strong heart."
"Yes, everything you said is right." Officer Wang walked to the middle of the crowd, frowning and expressed his opinion:
"If this He Liqiang is really such a person, it would be quite scary. He can turn lies into truth."
"The key is, which of the two went into the house first and killed Zhang Xia? We still don't know."
"But we can be sure that everything that happened next is true. One of the two people must have had murderous intentions and wanted to kill people and silence them."
"But since both of them are grown men and have similar body shapes in all aspects, if they beat each other, both sides will be hurt, and no one will take advantage."
"But just like this, we need to conduct an in-depth and comprehensive investigation of the scene again."
"After all, Gao Chuanfeng can only determine how the deceased died, but whoever takes action first has to rely on ourselves."
"Senior Brother Wang is right." As soon as Officer Wang finished speaking, Gu Chen snapped his fingers and said involuntarily:
"The current situation is that we have to re-judge whether the murderer is He Liqiang or Huang Zhiqiang?"
"Although the scene was a bit messy, our attention at the time was focused on arresting the suspect He Liqiang, so we did not check the scene too much."
After a pause, Gu Chen also thought about it and said, "In this case, leave it to Senior Brother Ding, Wu Xiaofeng, Ji Zhe and the others, and we will go to the crime scene again."
"Check the house again to see if there are any flaws?"
"OK."
"Listen to you."
"Then let's set off quickly."
After Gu Chen finished speaking, everyone also echoed in turn.
Since time was tight, everyone could not tolerate any delay, so they hurriedly drove back to the village in the city.
When we returned to the scene of the crime, it was already 7pm.
Everyone bought some pastries and milk on the roadside, and simply prepared for their own dinners.
At this moment, the guardrail outside the crime scene was also surrounded by a cordon, and two auxiliary police officers were on duty in turns.
When Gu Chen and others arrived, one of the auxiliary police officers was on duty while the other went out to eat.
Seeing Gu Chen's arrival, the auxiliary police officer sitting at the top of the stairs immediately stood up and saluted Gu Chen:
"Gu Bureau."
"Have you eaten?" Gu Chen asked.
"I just finished eating," the auxiliary police officer said.
"How is the situation inside?" Lu Weiwei also asked.
The auxiliary police officer followed the crowd and explained: "After you left the scene, the forensic experts from the Technical Section of the Municipal Bureau also came over to inspect the body."
"No one has been here since."
"Very good." Gu Chen nodded slightly, stood at the door, and along with everyone else, put on goggles, gloves, headgear and masks.
After completing all kinds of protective wear, he walked into the room and began to re-inspect the scene.
The living room was still full of messy and broken furniture.
The four of them stood in a row, looking up and down at their surroundings.
Afterwards, several people dispersed to investigate.
Gu Chen, on the other hand, stood in the center and input the images he just saw into his brain one by one.
Soon, Gu Chen used his master's imagination to quickly restore the fighting scene based on the damaged items at the scene.
A rainbow flashed across Gu Chen's mind, and two men fighting appeared in front of Gu Chen's eyes, namely Huang Zhiqiang and He Liqiang.
Since He Liqiang's body was covered with stab wounds, Gu Chen judged that the one holding the knife should be Huang Zhiqiang.
Huang Zhiqiang's body was covered with bruises and wounds, and his arms were slightly fractured. Therefore, Gu Chen judged that the person holding the wooden stick should be He Liqiang.
Based on the damage to the items, Gu Chen reconstructed various ways the two fought.
"But Zhang Xia died after being hit on the head with a wooden stick, and the man holding the wooden stick happened to be He Liqiang. So can I judge that there is a high probability that the murderer is He Liqiang?"
Gu Chen was thinking about these in his mind and returned to the real world.
In front of them, Lu Weiwei, Officer Wang and Yuan Shasha were still checking for abnormalities around the living room.
Gu Chen turned his head and looked at the room where Zhang Xia died.
Gu Chen couldn't think too much and walked quickly towards the room.
Soon, Gu Chen discovered that the place where Zhang Xia died had been drawn with chalk by forensic doctor Gao Chuanfeng.
There were blood stains everywhere on the surrounding walls and on the ground.
"Who smashed Zhang Xia's head? How could he be so vicious?" Gu Chen knelt down and looked at the outline of Zhang Xia lying on the ground in front of him and the various blood stains on the wall, and he couldn't help but have doubts in his heart.
Especially the blood stains on the walls were almost in a splattered state, with many blood spots.
It can be seen that when Zhang Xia was attacked, the opponent's attack was brutal.
"Junior Brother Gu, Zhang Xia must have been suddenly attacked at that time and had almost no time to react."
"Judging from the autopsy report sent by Gao Chuanfeng from the Technical Section of the Municipal Bureau, there were no fibers or any human tissue between the fingers of the deceased Zhang Xia."
"Therefore, Gao Chuanfeng judged that the deceased should not have had a fierce fight before his death."
"That's for sure, because whether it's Huang Zhiqiang or He Liqiang, they are familiar enough with Zhang Xia, so Zhang Xia is undefended to them." Gu Chen also based on Gao Chuanfeng's autopsy.
The report analyzed.
At this moment, Yuan Shasha, who was also reading the autopsy report sent by Gao Chuanfeng on her mobile phone, couldn't help but said:
"The murderer suddenly attacked Zhang Xia when she was unprepared. Moreover, it can be seen from the injuries on the head of the deceased Zhang Xia that it should be a frontal attack."
"It can be seen that Zhang Xia was talking to the murderer at that time, or maybe in the middle of an argument."
"So the murderer picked up the wooden stick in his hand and smashed it directly into Zhang Xia's head, and Zhang Xia died on the spot."
"Could it be He Liqiang? After all, the murder weapon he used was a wooden stick." Officer Wang raised his eyebrows and said.
But Lu Weiwei shook her head: "Not necessarily, but it's very likely."
"Because, according to Huang Zhiqiang, as soon as he entered the door, he found He Liqiang staying at his home, and when he saw him, he wanted to kill him without saying a word."
"And He Liqiang was holding the wooden stick in his hand at that time, and Huang Zhiqiang also suffered multiple injuries and even fractures to his arm after being beaten."
"In order to save his life, Huang Zhiqiang relied on his familiarity with the items in the house to find a fruit knife, then struggled with He Liqiang, and finally stabbed He Liqiang, and He Liqiang fled."
"But in this way, Huang Zhiqiang's statement seems to be more reliable."
Looking at Gu Chen, Lu Weiwei added: "Of course, according to Junior Brother Gu, this is not absolute."
"Yes, it's hard to judge from this point alone." As Gu Chen spoke, he repeatedly compared the shape of the blood on the wall at the scene, and then explained to everyone:
"Have you noticed? There may be hundreds or thousands of drops of blood splattered on the wall here."
"Moreover, among the thousands of drops of blood, I found a kind of forward-swinging blood stain."
"Spreading blood with a forward swing?" Everyone heard this and all said in unison, and then quickly gathered around and rechecked the shape of the blood drops on the wall according to Gu Chen's prompts.
While Lu Weiwei was inspecting, she couldn't help but say: "Yes, after the blood flows out of the body, it will come into contact with different objects at the scene to form blood stains."
"Different bloodstain forms are caused by different formation mechanisms, environments, processes, etc."
"As for blood spatters, they are blood stains caused by rupture of human arteries and blood spurting out at a certain angle with the ground or wall. The power comes from the blood pressure of the arteries."
"On a flat object, the typical shape of spattered bloodstains is a straight line or a larger oblong bloodstain spread in a curve."
After a pause, Lu Weiwei continued: "As for the flying direction of the blood droplets, the angle with the plane carrier is small, usually less than 60 degrees."
"Because the heart contracts and relaxes rhythmically, blood spatters are often intermittent and distributed in groups, but the blood stains formed later are generally lower in height and closer than those formed before."
"Yes." Officer Wang squinted and carefully observed the blood on the wall, and couldn't help but say:
"Actually, a typical blood spatter is in the shape of a long strip, with one end enlarged and the other end thin and narrow."
"The edge of the enlarged end is smooth, and the other end usually has a tailing phenomenon. The tip indicates the direction of the blood spatter, and some are shaped like an exclamation mark."
"The larger the angle between the blood spatter and the object when it is formed, the closer its shape is to an oval or circle, and vice versa, it is close to an exclamation mark."
"When the angle with the ground is about 15 degrees, the shape of the blood spatter is the most slender. Another characteristic of the blood spatter is that the blood stains are often arranged radially, in a straight line or arc."
"Yeah." After hearing Officer Wang's words, Gu Chen nodded slightly and continued:
"We have seen many blood drop shapes before, like dripping blood stains. The blood is in a state of free fall and forms blood stains on the carrying object."
"The blood volume is generally in the range of 0.025 to 0.05ml, and its shape is directly related to the angle when the blood droplets come into contact with the carrier."
"When the blood drops are in vertical contact, the blood stains will be round or nearly round. When the blood drops are in contact at a certain angle, the blood drops will be oval."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "And the dripping blood in the moving state often has a splash shape on one side in the direction of movement. Its size and range are related to the speed of movement.
The height of fall is directly proportional to the amount of blood.
"Among them, the edge changes and splash changes of blood droplets actually have certain regularity."
"If it is a smooth object, then the lower the height of the blood, the smaller the impact force. The blood droplets will be round, with smooth edges and no splashing around."
"If it is an impact-type bloodstain, the bloodstain is formed when an external force hits the human body, or the bloodstain is spattered after the original bloodstain, and its diameter is usually not larger than 2mm."
"But occasionally, blood stains with a diameter of about 5mm can be seen, but when the external force exerted is very large, such as gunshots and explosions, the diameter of the blood stain is often less than 1mm."
"Special collision blood stains like this are also called blood mist, but they are not found here."
"And because the collision blood stains are mostly radially distributed and have obvious directionality, they are often formed all at once, and there is only one bleeding point."
"Isn't there still blood stains from hemoptysis?" Yuan Shasha said casually after listening to Gu Chen's story.
Gu Chen nodded slightly, looked at the blood stains on the wall and analyzed: "Yes, the blood stains from hemoptysis refer to the respiratory organs below the throat."
"Usually it is a process in which the trachea, bronchi, or lung tissue bleeds and is expelled from the mouth through coughing."
"But because the intensity of hemoptysis is different, the shape of the blood stains also changes quite a lot."
"But their common feature is that there are often bridge-like blood stains connecting multiple dot-like blood stains."
"And the reason for the formation of this special shape of blood stains is that the blood coughed up in the trachea is often mixed with mucus and even sputum secreted by the tracheal wall cells, and the blood viscosity will be greatly increased."
After looking at the walls and the ground, Gu Chen added: "But, there is none here."
"I even thought about whether there would be transferred blood stains here? After all, an object contaminated with blood will leave special traces on another object through direct contact."
"It's like bloody handprints, bloody palm prints, bloody footprints, etc., but there are none here either."
"What about the blood stains on Liuzhu?" Yuan Shasha also looked around and said casually.
Gu Chen analyzed calmly and continued: "Blood stains? So far, no blood stains have been found. After all, blood stains are affected by gravity and will move downward along the surface of the object to form blood stains."
"In fact, the typical shape of blood stains from a stream is usually in the shape of a column, thick at the top and thin at the bottom, light at the top and thick at the bottom. Its length and thickness are directly proportional to the blood volume and the slope of the object."
"And I have also checked that there is no obvious pool of blood here. After all, there is no certain volume of blood."
"If it is a pool of blood, it needs to be gathered by gravity to form a blood stain."
"And the formation of blood pools is directly related to factors such as bleeding time, bleeding volume, blood aggregation method, and the adsorption of the carrier."
"When the blood volume is large and not completely dry, due to gravity and sedimentation, serum and formed components can be separated in the blood pool, resulting in a change of dark red in the middle and light yellow at the edge."
"And I just checked the scene, and I thought it was stained with blood."
"After all, if it is stained with blood, then the blood will form blood stains on adsorbent objects, which is usually called bleeding."
"Moreover, the blood stains are evenly spread and have a certain area. They are affected by factors such as the amount of bleeding, body position, and the texture of the stained material, and have no fixed shape."
"Yes, but there are some spewing blood stains." Lu Weiwei also discovered a problem during the inspection, and then said:
"There is a lot of blood here. Overall, it should be blood stains formed from damaged and ruptured blood vessels."
"Compared with splattered bloodstains, the bleeding volume of spewing bloodstains is larger, but the kinetic energy when forming is smaller, so the shape is not as regular as splattered bloodstains."
"But there is no blood stains wiped here, because the blood stains caused by the blood-stained objects directly contacting the carrier through rubbing and other movements do not appear."
"If it is affected by many factors such as the shape of the blood-stained object, the amount of blood, the shape of the carrier, and the method of contact, the shape of the wiped blood stain will be very different."
"And I took a look just now. Maybe this situation does not exist. As for what Junior Brother Gu said, blood stains are scattered with the forward swing, but it is true."
"Yeah." After listening to Lu Weiwei's words, Gu Chen nodded silently, then pointed out the specific location and said:
"As you can see, the shape of the blood is very obvious. It was thrown by the murderer when he swung the stick to kill."
"Also, there is a question. I wonder if you have discovered it?"
Seeing that Gu Chen was trying to pass things off, everyone looked at each other and continued to look at the wall, trying to figure it out carefully.
It was Lu Weiwei who discovered the trick first and quickly explained to everyone:
"The murderer may be a left-handed man, because we have found this kind of blood stains before when we were investigating the case."
"However, usually, the shape distribution is in the opposite direction to the current blood shape."
"Based on the injured area of the deceased Zhang Xia, it seems that the murderer should have used his left hand to hold a wooden stick and hit Zhang Xia's head hard."
"That's right." As soon as Lu Weiwei finished speaking, Gu Chen agreed with Lu Weiwei's words and couldn't help but say:
"Based on the analysis of the blood shape, the murderer is indeed holding the stick in his left hand. From this point of view, the murderer is probably left-handed."
"Left-handed?" After listening to Gu Chen's words, Officer Wang also began to figure it out, and muttered:
"Then is it Huang Zhiqiang who is left-handed? Or is it He Liqiang? If the murderer is left-handed, it would be easier. This is easy to find out."
"One more thing." As soon as Officer Wang finished speaking, Gu Chen said again:
"I noticed the clothes of Huang Zhiqiang and He Liqiang. They both had blood stains on their bodies."
"If it is the murderer of Zhang Xia, then the murderer must have some blood stains of Zhang Xia during the crime."
This chapter is not over yet, please click on the next page to continue reading the exciting content! "But have you noticed?"
"I know." As soon as Gu Chen finished speaking, Yuan Shasha said immediately: "Both of them said that after they entered the house, they found the other person standing there and started fighting with them."
"In other words, neither of the two people at that time saw the specific location of the deceased Zhang Xia."
"Then if Zhang Xia's body was not seen, there would be no traces of Zhang Xia's blood."
"As long as you find one of them without Zhang Xia's blood, you can determine who is innocent."
"This is only relatively speaking." Yuan Shasha finished speaking, and Gu Chen added:
"Though through this, we can indeed judge who was wrongly accused."
"But have you ever thought about it? If, I mean if, if the stick in He Liqiang's hand was the murder weapon."
"Then, during his fight with Huang Zhiqiang, Zhang Xia's blood was originally stained on the wooden stick, so it is very likely that Huang Zhiqiang's body was stained with Zhang Xia's blood."
"On the contrary, if Huang Zhiqiang deliberately gave the stick to He Liqiang, and then He Liqiang counterattacked Huang Zhiqiang, what would be the result?"
After the words fell, the scene suddenly became quiet.
Officer Wang also frowned and asked Gu Chen: "Gu Chen, what do you think we should do?"
"First of all, we need to quickly find out who is left-handed. This is more certain."
"And I noticed that the pants of these two people were stained with blood from their fight."
"However, if it is the murderer, then there must be Zhang Xia's bloodstains. The shape of the bloodstains on the pants of the two people can actually be compared with the bloodstains on the wall."
"And the problem is that the shape of the blood stains at the scene is very special, it is a medium-speed splatter type blood stain."
"This kind of blood can only splatter out when a person is hit when he is alive."
"And these blood stains can be used as important evidence. I have even observed here to see if there are any bouncing, splattering or transfer blood stains?"
"After all, the shape of blood spatter is an important part of on-site reconstruction. When blood hits the surface of an object, it will produce different shapes due to different surface structures and adsorption properties."
"From the blood spatter pattern, we can infer the crime process, the victim, or the suspect's relevant information, etc., and can all be restored."
After looking at everyone, Gu Chen added: "For example, from the shape of the blood stain, we can actually infer the location, height and angle of the moment the blood spattered."
"If the blood stain is round, it means the blood dripped from a short distance away, at least less than twelve inches."
"But if it's jagged, it means the dripping distance is greater than twelve inches. If it's like an exclamation mark, the blood hits and falls along the small dot at the end of the exclamation mark."
"But from the shape of the blood stain and the size of the blood droplets, we can also distinguish the speed and power of the blood splash."
"If the blood is ejected and migrated at a low speed, its force is very small. This common blood stain is caused by blood dripping on the ground after an injury."
"If it is medium speed, it means the power is medium, the edges of the blood drops are uneven, and in addition to the main blood drops, there will be some scattered tiny blood spots."
"Generally speaking, this kind of blood stains come from blows, knife wounds, sticks, hammers, etc."
"If it is blood droplets splashing at high speed, it means that the impact force is very strong, the blood droplets are widely spread, and there will be tiny spray-like blood spots scattered in the center and around the impact area."
"Yes." After listening to Gu Chen's words, Lu Weiwei couldn't help but said:
"Actually, I originally thought it was the blood stains from the stab wound, but in addition to the shape, speed and strength, it also depends on the location of the wound."
"If you cut it in the muscle, there won't be much blood, but if you cut it in the vein, the blood will flow out."
"But if you cut an artery, the blood will spurt out faster."
"In addition, I also checked the ceiling outside the blood stains on the wall. I feel that Zhang Xia's forehead was smashed by the murderer without any precautions."
"If both Huang Zhiqiang and He Liqiang have this kind of medium-speed splatter blood stains on their bodies, then it will be easy to determine who the murderer is?"
"In addition, as long as we find out who is left-handed, we can basically identify the murderer."
"Yeah." Listening to Lu Weiwei's analysis, everyone can basically judge the specific characteristics of the murderer.
Fortunately, neither Huang Zhiqiang nor He Liqiang had time to change their clothes, so the blood stains remained.
Even if both people insist on their own opinions, the evidence often lies in the details.
No matter how much the two lie, as long as these clues match, the murderer can basically be identified.
"Then what are you waiting for? Let Lao Ding, Wu Xiaofeng and Ji Zhe help us confirm whether there are any such blood stains on these two guys?"
"Also, if you look at who is left-handed, he basically has no chance of running away."
"Wait a minute." After Officer Wang finished speaking, Gu Chen seemed to have made a new discovery.
The whole person walked to the wall, and his eyes began to look surprised.
Seeing this, Lu Weiwei asked curiously: "What's wrong, Junior Brother Gu? Haven't the clues been found?"
"Although the clues have been found, but..." Gu Chen frowned, and there was a hint of fear in his eyes.
