Chapter 2158

In the end, Ah Qiang seemed to have more time to spare, with panic on his expression.

Gu Chen thought that the evidence for this case was conclusive, but now it seems that the arguments between He Liqiang and Huang Zhiqiang are both sticking to each other.

Moreover, even if He Liqiang was the murderer, would the murderer be so stupid that he would come to the hospital for treatment after committing a crime?

At the very least, you have to hide, and it is safer to find a small clinic for treatment.

But it is this kind of truth that ordinary people understand, how could He Liqiang not understand it?

Moreover, He Liqiang is also full of scars at this moment. Compared with the scars on Huang Zhiqiang's body, He Liqiang's wounds are mostly knife wounds, and there are crossings in many parts.

It is conceivable that if Huang Zhiqiang had been more ruthless, He Liqiang could almost have received a lunch box.

"He Liqiang." Gu Chen pointed to He Liqiang in front of him, and said involuntarily, "You said Huang Zhiqiang killed her wife, what do you think was the motive?"

"What else could it be?" He Liqiang took a deep breath and said after a moment of fear:

"I don't think he knew about my relationship with his wife."

"As for how I found out? I don't know very well. Originally, I went there today to make it clear to his wife, Zhang Xia, and tell her not to look for me again. It's as simple as that."

"But I don't know, why? Why did he know in advance? And he killed his wife."

"Let's go back and investigate this. Now, you have to go back to the police station with us." Lu Weiwei said.

"Yes, of course, as long as you don't meet that lunatic, you can go anywhere." After He Liqiang finished speaking, he also took a deep breath.

It seems that he has not recovered from the previous cruel state.

After He Liqiang was brought back to the police station, Huang Zhiqiang was also brought back by Ding Liang and Huang Zunlong.

He Liqiang was in the No. 1 interrogation room, writing his story, while Huang Zhiqiang was in the No. 2 interrogation room.

Since the confessions of the two have two completely opposite statements, it is difficult for Gu Chen to judge now. Are the two lying in bed?

In the corridor outside the interrogation room, Gu Chen's cell phone rang suddenly.

Seeing that it was Gao Chuanfeng from the Technical Section of the Municipal Bureau, Gu Chen immediately pressed the answer button: "Gao Chuanfeng."

"Gu Chen, the corpse you sent over, we did a preliminary inspection and found that he was hit on the head with a wooden stick and died."

"In particular, the skull of the deceased was also broken by wood, and we found fragments of wooden sticks at the head of the deceased."

"Also, we found the bloody wooden stick at the scene and confirmed it was the murder weapon."

"Knocked to death by a wooden stick?" Hearing such an answer, it was also in line with Gu Chen's previous judgment.

Gu Chen nodded slightly, and then asked Gao Chuanfeng: "Apart from this, have you found any other abnormalities?"

"Not yet. I'm only in charge of body testing. Besides, haven't you already gone to track down the murderer? How is 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 blame the other for killing the deceased Zhang Xia."

"And the statements of the two are diametrically opposed. We now need to re-investigate the cause of death of the deceased, as well as the specific murderer."

After a pause, Gu Chen said again: "So, Gao Chuanfeng, if you find anything over there, remember to notify 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 is it?" 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 a skull smashed by a wooden stick. However, is the murderer her husband Huang Zhiqiang? Or that He Liqiang? For 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 say?"

"What else can I say?" Lu Weiwei took a deep breath, and said in a bad mood:

"Both of them are still insisting on their own views, saying 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 dictated before may all be false."

Leaning 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 today he wanted to go to Zhang Xia's house and talk to her clearly, but happened to run into Huang Zhiqiang who was at home, so the two started fighting, which is a bit strange."

"First of all, is it really such a coincidence? It happened today that He Liqiang found out with conscience and wanted to go over and explain clearly to Zhang Xia."

"What's the matter, wouldn't he, He Liqiang, talk to Zhang Xia clearly on the phone? But he insisted on going to Zhang Xia's house? This is very confusing."

"Also, even if Huang Zhiqiang found out that his wife, Zhang Xia, had an affair with He Liqiang, how about murder?"

"It's not impossible, right?" Police officer Wang walked over and said:

"Some people, once stimulated, can do anything."

"What's more, this He Liqiang is still a very good friend with me. I can't bear my friend's greening of me."

"I think that Huang Zhiqiang at this time should have completely lost his mind. It is entirely possible to kill Zhang Xia and He Liqiang if he takes action."

"Yeah, I also think what Senior Brother Wang said makes sense. After all, impulsiveness is the devil. Many incidents are actually caused by the parties losing their minds and impulsiveness."

"So, after Huang Zhiqiang learned that his wife and friends were together behind his back, he must have been furious."

"If you say, who has the more motive to kill, I think it should be Huang Zhiqiang."

"After all, if you think about it, He Liqiang himself is at a loss. Why did he kill Zhang Xia, who had an affair with him? What good does it do him? The motive for killing is not strong." Yuan Shasha also shared her thoughts with everyone. come out.

Gu Chen shook his head: "Although what Xiao Yuan said is reasonable, it also conforms to normal logic."

"However, some things cannot be explained by this normal logic."

After a pause, Gu Chen looked around, and then said, "This He Liqiang doesn't seem to have much motive for killing, but who knows, did he have any other secrets before he and Zhang Xia?"

"As for He Liqiang, could it be because Zhang Xia has some clues about him? Could he be thinking of killing Zhang Xia? If we don't investigate these things in depth, they may cease to exist."

"So Huang Zhiqiang is more likely to have the motive for the murder, but that doesn't mean He Liqiang doesn't have it."

"Yes." Listening to Gu Chen's remarks, Lu Weiwei also nodded silently, and said involuntarily:

"Now these two people are saying that the father is right and the wife is saying that the woman is right. Huang Zhiqiang insists that He Liqiang killed his wife Zhang Xia."

"And He Liqiang insisted that it was Huang Zhiqiang who killed his wife Zhang Xia."

"But according to Huang Zhiqiang, he was a victim from the beginning to the end. He said that after he entered the house, he found He Liqiang staying at home, and then attacked himself."

"He Liqiang's statement is also very similar. He also found out that Huang Zhiqiang wanted to kill him as soon as he entered the door."

"And He Liqiang also said that he and Zhang Xia actually had an improper relationship between men and women, but did they have some nepotism interests? We haven't investigated this."

"If you say that He Liqiang's visit to Zhang Xia's house this time is not to draw a line with Zhang Xia, but because of some conflicts, he needs to clarify with Zhang Xia."

"Thus he missed, or killed Zhang Xia on his own initiative, so at this time, he happened to meet Huang Zhiqiang who was returning home, and the two wrestled again. After they escaped by themselves, they pretended to be a victim. This is also entirely possible."

"Uh." Listening to Lu Weiwei's explanation, Yuan Shasha was stunned for a few seconds, and said analytically:

"If you follow Senior Sister Lu's analysis, you are right. If He Liqiang is really the murderer, then this guy is too scary."

"Think about it, he killed Zhang Xia, and then wrestled with Huang Zhiqiang. Both sides can be regarded as losers."

"But after He Liqiang escaped from the room, he didn't choose to hide, but ran to the hospital for treatment in a grand manner."

With a faint sigh, trying to calm down, Yuan Shasha couldn't help but say, "This kind of courage is probably beyond the reach of ordinary murderers. It requires a strong heart."

"Yes, what you said is correct." Officer Wang walked among the crowd, frowned, and expressed his opinion:

"If this He Liqiang is really such a person, it would be quite scary. He can tell lies to be true."

"The point is, which of the two entered the house and killed Zhang Xia? We still don't know."

"However, I can be sure that everything that happened later was correct. Among the two, one of them must have murderous intentions and wanted to kill people to silence them."

"However, due to the fact that both of them are grown men, their body types are similar in all aspects. When they beat each other, both sides will suffer, and no one will take advantage of it."

"But in this way, we need to conduct an in-depth and comprehensive investigation of the scene again."

"After all, on Gao Chuanfeng's side, we can only judge how the deceased died, but whoever makes the first move depends on us."

"Senior Brother Wang is right." As soon as Police 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 was focused on arresting the suspect He Liqiang, so we didn't check the scene too much."

After a pause, Gu Chen also thought about it and said, "Well, let's leave this to Senior Brother Ding, Wu Xiaofeng and Ji Zhe, and the rest of us, let's go to the discovery site again."

"Re-examine the house at that time to see if there are any other flaws?"

"OK."

"Listen to you."

"Then let's go quickly."

It was also after Gu Chen's voice fell that everyone echoed in turn.

Due to time constraints, 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 eucalyptus discovery, it was already 7 o'clock in the evening.

Everyone bought some pastries and milk on the side of the road, and it was also a simple way to deal with their own dinners.

At this moment, the position of the guardrail outside the scene was surrounded by a cordon, and two auxiliary policemen took turns guarding it.

When Gu Chen and the others arrived, one of the auxiliary policemen was on duty while the other went out to eat.

Seeing Gu Chen's arrival, the auxiliary policeman sitting at the top of the stairs immediately stood up and saluted Gu Chen:

"Gu Bureau."

"Did you eat?" Gu Chen asked.

"Just finished eating," said the auxiliary policeman.

"How's the situation inside?" Lu Weiwei also asked.

The auxiliary policemen followed behind everyone, and explained, "After you left the scene, the senior forensic doctor from the technical department of the Municipal Bureau also came to inspect the corpse."

"After that, no one came here again."

"Very good." Gu Chen nodded slightly, stood at the door, and joined the crowd, wearing foot gloves, gloves, headgear and masks.

After completing all kinds of protective wear, he walked into the room and began to re-examine the scene.

In the living room, there are still messy and damaged furniture.

The four of them stood in a row, looking up and down at the surrounding situation.

Afterwards, several people dispersed to investigate one by one.

Gu Chen, on the other hand, stood in the center, inputting the images he saw just now into his brain one by one.

Soon, Gu Chen used his master-level imagination to quickly restore the fighting scene at that time based on the damaged items on the scene.

A rainbow flashed across his brain, and Gu Chen saw two fighting men, Huang Zhiqiang and He Liqiang.

Since He Liqiang had knife wounds all over his body, Gu Chen judged that Huang Zhiqiang should be holding the knife.

But Huang Zhiqiang's body was covered with bruises and wounds everywhere, and his arm was slightly broken, so Gu Chen judged that the person holding the wooden stick should be He Liqiang.

According to the damage of the item, Gu Chen restored multiple fighting methods between the two.

"But Zhang Xia died from 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 was He Liqiang?"

Gu Chen thought about this in his heart, and returned to the real world.

In front of him, Lu Weiwei, Police Officer Wang and Yuan Shasha were still checking for abnormalities around the living room.

Gu Chen turned his head to look at the room where Zhang Xia died.

Gu Chen couldn't bear to think too much, and walked quickly towards the room.

Soon, Gu Chen discovered that the place of Zhang Xia's death had already been drawn by forensic doctor Gao Chuanfeng with chalk.

On the surrounding walls and on the ground, there were bloodstains everywhere.

"Who fell to the ground and smashed Zhang Xia's head? The strike was so vicious?" Gu Chen squatted down, looking at Zhang Xia's fallen silhouette and various blood stains on the wall in front of him, he couldn't help feeling suspicious.

Especially the bloodstains on the wall, almost in a state of spattering, with many spots of bloodstains.

It can be seen that when Zhang Xia was attacked at that time, the opponent's attack was fierce.

"Junior Brother Gu, at that time Zhang Xia must have found the sudden attack, and there was almost no time to react."

"According to the autopsy report sent by Gao Chuanfeng, the Technical Section of the Municipal Bureau, the deceased Zhang Xia's fingers did not have any fibers or any human body to prevent them."

"Therefore, Gao Chuanfeng judged that the deceased should not have fought fiercely during his lifetime."

"That's for sure, because whether it is Huang Zhiqiang or He Liqiang, the relationship between the two of them and Zhang Xia is familiar enough, so Zhang Xia is defenseless to them." Gu Chen also based on Gao Chuanfeng's autopsy The report analyzed.

At the moment, Yuan Shasha, who was also reading the autopsy report sent by Gao Chuanfeng on her mobile phone, couldn't help but say:

"The murderer made a surprise attack when Zhang Xia was unprepared. Moreover, it can be seen from the injured part of Zhang Xia's head that it should be a frontal attack."

"It can be seen from this that Zhang Xia was talking with the murderer at that time, and may also be arguing."

"So the murderer picked up the wooden stick in his hand and threw it directly at Zhang Xia's head, and Zhang Xia died on the spot."

"Could it be He Liqiang? After all, the murderer he used was a wooden stick." Officer Wang said with raised eyebrows.

But Lu Weiwei shook her head: "Not necessarily, but the possibility is very high."

"Because, according to Huang Zhiqiang, as soon as he entered the house, he found that He Liqiang was staying at his house, and upon seeing him, he would have killed him without saying a word."

"Besides, He Liqiang was holding that wooden stick in his hand at that time, and Huang Zhiqiang was also injured in many places and even fractured 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 wrestled with He Liqiang, and finally stabbed He Liqiang, and He Liqiang escaped."

"But in this way, Huang Zhiqiang's statement seems to be more reliable."

Glancing at Gu Chen, Lu Weiwei said again: "Of course, according to Junior Brother Gu, this is not absolute."

"Yes, it's hard to judge from this alone." Gu Chen repeatedly compared the shape of blood on the wall of the scene, and then explained to everyone:

"Have you noticed? There may be hundreds or even thousands of drops of blood splashed on the wall here."

"Moreover, among the thousands of drops of blood, I found a forward-swinging bloodstain."

"Front swing to scatter blood?" Everyone heard the words,

They also spoke in unison, and then hurriedly gathered around, according to Gu Chen's prompt, to check the shape of the blood drop on the wall again.

While Lu Weiwei checked, she couldn't help but say, "That's right, after the blood flows out of the body, it will contact with different objects in the scene to form blood stains."

"And different bloodstain shapes are caused by different formation mechanisms, environments, processes, etc."

"As for the blood splatter, it is the blood splatter formed by the rupture of the human artery and the blood spraying out at a certain angle with the ground or wall. The power comes from the blood pressure of the artery."

"Uh, on a flat object, the typical shape of the blood splatter is a straight line, or a large oblong blood splattered in a curved shape."

After a pause, Lu Weiwei continued: "As for the flying direction of the blood splattered blood droplets, the angle with the plane carrier is relatively small, usually less than 60 degrees."

"Because the heart contracts and relaxes rhythmically, blood splatters are often intermittent and distributed in groups, but the blood splatters formed later are generally lower in height and closer in distance than the blood splatters formed earlier."

[In view of the general environment,

"Yes." Police Officer Wang squinted his eyes and carefully observed the blood on the wall, and said involuntarily:

"Actually, typical blood splatters are long strips, one end is enlarged, and the other end is thin and narrow."

"The edge of the enlarged end is smooth, and the other end usually has a trailing phenomenon. The tip indicates the direction of the blood spatter, and some are shaped like an exclamation point."

"The greater the angle between the blood splatter and the object, the closer its shape is to an ellipse or circle, and vice versa, it is closer to an exclamation mark."

"When the angle with the ground is about 15 degrees, the shape of the splattered bloodstains is the most slender, and another characteristic of the splattered bloodstains is that the bloodstains are often arranged radially, on a straight line or an arc."

"En." Hearing Officer Wang's remarks, Gu Chen also nodded slightly, and continued:

"We have also seen many blood drop shapes before, like dripping blood, which is a blood stain formed on the carrying object in a free-falling state of blood."

"Its blood volume is generally in the range of 0.025 to 0.05, and its shape is directly related to the angle at which the blood drop contacts the carrier."

"When the blood drop touches vertically, the blood stain is round or almost round; when the blood drop touches at a certain angle, the blood drop is oval."

"The dripping blood in the state of motion, in the direction of motion, often has a splash shape on one side, and its size and range are proportional to the speed of motion, the height of the drop and the size of the blood volume.

"Among them, the edge changes and splash changes of blood droplets actually have certain regularity."

"If it is a smooth object, the lower the height of the blood, the smaller the impact force, the blood drop is round, with smooth edges, and there is no splash around."

"If it is an impact-type bloodstain, the diameter of the bloodstain formed by the impact of an external force on the human body, or the bloodstain formed by sputtering after the original bloodstain is usually not greater than 2."

"However, it can occasionally be seen that the diameter is about 5, but when the external force is very large, such as gunshots or explosions, the diameter of blood stains is often less than 1."

"This kind of special collision bloodstain is also called blood mist, but it has not been found here."

"Because the bloodstains from the collision are mostly radially distributed and have obvious directionality, they are often formed at one time, and there is only one bleeding point."

"Isn't there still hemoptysis?" Yuan Shasha also said casually after listening to Gu Chen's narration.

Gu Chen nodded slightly, looked at the blood on the wall and analyzed: "That's right, the hemoptysis refers to the respiratory organs below the throat."

"Usually bleeding from the trachea, bronchi, or lung tissue, which is expelled from the mouth through a coughing action."

"However, due to the different intensity of hemoptysis, the shape of the blood stains also changes considerably."

"But their common feature is that there are often bridge-shaped bloodstains connecting each other between multiple point-shaped bloodstains."

"And the reason for the formation of this special form of blood is that the blood spit out from the trachea is often mixed with mucus and even sputum secreted by the cells of the trachea wall, and the blood viscosity will be greatly increased."

Looking at the wall and the ground, Gu Chen said again: "But, there is no such thing here."

"I even wondered if there would be traces of transferred blood here. After all, an object contaminated with blood will leave traces with a special shape on another object through direct contact."

"It's like bloody handprints, bloody palmprints, bloody footprints, etc., but there are none here either."

"What about the bloodstains?" Yuan Shasha also looked around and said casually.

Gu Chen analyzed calmly, and continued: "Bloodstains? So far, no one has found them. After all, bloodstains are affected by gravity. The blood will move down the surface of the object to form bloodstains."

"Actually, the typical shape of a bloodstain 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. The length and thickness are proportional to the blood volume and the slope of the object."

"And I also checked, there is no obvious pool of blood here, after all, there is no blood of a certain volume."

"If it's a pool of blood, it needs to gather to form a blood stain under the action of gravity."

"And the blood pool formation is directly related to factors such as bleeding time, bleeding volume, blood aggregation method, and carrier adsorption."

"When the blood volume is large and not completely dry, due to gravity and sedimentation, the serum and formed components can be separated in the blood pool, resulting in dark red in the middle and light yellow at the edge."

"And I checked the scene just now, I thought about soaking in blood."

"After all, if it is soaked with blood, then the blood will form a blood stain on the absorbent object, which is usually called bleeding."

"Moreover, the blood stains are evenly diffused and have a certain area. They are affected by factors such as the amount of bleeding, the texture of the stain, and the texture of the stained matter, and have no fixed shape."

"Yes, but there are some, spurting blood." During the inspection, Lu Weiwei also found a problem, and then said:

"There's a lot of blood here. Looking at it as a whole, it should be bloodstains gushing out from damaged and ruptured blood vessels."

"Compared to blood splatters, blood splatters bleed more heavily, but they form with less kinetic energy, so their shape is less regular than blood splatters."

"However, the bloodstains were not wiped here, because the bloodstains formed by the direct contact of the blood-stained object with the carrier through movements such as rubbing did not appear."

"If it is affected by various factors such as the shape of the blood-stained object, the size of the blood volume, the shape of the carrier, and the way of contact. There will be a big difference in the shape of wiping the blood."

"And I just looked at it, maybe this kind of situation does not exist. As for what Junior Brother Gu said, the forward swing splatters blood, but it does exist."

"En." Hearing Lu Weiwei's remarks, Gu Chen also nodded silently, and then said with empathy:

"As you can see, the shape of the blood is actually very obvious. It was thrown by the murderer when he swung his stick to kill people."

"Also, there is a problem, I wonder if you have noticed it?"

Seeing Gu Chen's trickery, everyone looked at each other in blank dismay, and continued to look at the wall, trying to figure it out carefully.

It was Lu Weiwei who was the first to discover the trickiness, and quickly explained to everyone:

"The murderer may be left-handed, because we have also found this kind of blood when we were investigating the case before."

"However, under normal circumstances, the shape distribution is in the opposite direction to the current blood shape."

"According to the injured part of the deceased Zhang Xia, I feel that the murderer should have held a wooden stick in his left hand and slammed it towards Zhang Xia's head."

"That's right." As soon as Lu Weiwei finished speaking, Gu Chen also agreed with Lu Weiwei's words, and said involuntarily:

"According to the analysis of the blood shape, the murderer is indeed holding a stick in his left hand. From this point of view, the murderer is likely to be left-handed."

"Left-handed?" Hearing Gu Chen's remarks, Police Officer Wang also began to ponder, and said in his mouth:

"Then is it Huang Zhiqiang who is left-handed? Or He Liqiang? If the murderer is left-handed, it will be easier to find out."

"One more thing." Just as Police Officer Wang finished speaking, Gu Chen said again:

"I have noticed the clothes of Huang Zhiqiang and He Liqiang. Both of them have blood stains on their bodies."

"If it was the murderer who killed Zhang Xia, then the murderer must have possessed some of Zhang Xia's blood during the murder."

"But have you noticed?"

"I know." As soon as Gu Chen finished speaking, Yuan Shasha immediately said, "Both said that after entering the room, they found the other party standing there and started fighting with themselves."

"That is to say, neither of the two people at that time saw the physical location of the deceased Zhang Xia."

"Then if you didn't see Zhang Xia's body, there wouldn't be Zhang Xia's blood on it."

"As long as one of them is found without Zhang Xia's blood, we can determine who is innocent."

"This is only relative." Yuan Shasha's voice fell here, and Gu Chen added:

"Although through this point, it is indeed possible to judge who was wronged."

"But have you ever thought about it? If, I mean if, if the wooden stick in He Liqiang's hand is the murder weapon."

"Then, during the fight with Huang Zhiqiang, Zhang Xia's blood was already on the wooden stick, so it is very likely that Huang Zhiqiang's body was also stained with Zhang Xia's blood."

"On the contrary, if Huang Zhiqiang deliberately gave up the wooden stick to He Liqiang, and then He Liqiang was in the process of counterattacking Huang Zhiqiang, what would the result be?"

After the voice fell, the scene suddenly became quiet.

Officer Wang also frowned, and asked Gu Chen, "Then Gu Chen, what do you think should be done?"

"First of all, we still need to quickly find out who is left-handed. This point is more certain."

"And I have noticed that the pants of these two people are covered 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 two people's pants can actually be compared with the bloodstains on the wall."

"And the problem is that the shape of the bloodstains at the scene is very special, it is a medium-speed splatter type of bloodstain."

"This kind of blood can only be sprayed out when a person is alive and when he is hit."

"And these bloodstains can be used as important evidence. I even observed here, are there any bounce-type, splash-type, transfer-type bloodstains?"

"After all, the form of blood splatter is an important part of on-site reconstruction. When blood hits the surface of an object, it will produce different forms due to the difference in surface structure and adsorption."

"From the shape of the blood splatter, we can infer the crime process, the victim, or the relevant situation of the suspect, etc., can all be restored."

After looking at everyone, Gu Chen said again: "For example, from the shape of the blood stain, we can already deduce the location, height and angle of the blood splash at the moment."

"If the bloodstain is round, it means that the blood dripped from not far 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 in the shape of 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 bloodstain and the size of the blood droplet, we can also distinguish the speed and force of the blood splash."

"If the blood is ejected at a low velocity, it has very little force. This common blood stain is caused by blood dripping on the ground after an injury."

"If it is at a medium speed, it means that the strength is medium, and the edge of the blood drop is irregular. In addition to the main blood drop, there will be some scattered tiny blood spots."

"In general, this kind of blood is 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, and the blood droplets are widely scattered. There will be spray-like tiny blood spots scattered in the center and around the impact area."

"Yes." Hearing Gu Chen's words, Lu Weiwei couldn't help but say:

"Actually, I thought it was blood from a knife wound, but in addition to looking at the shape, speed and strength, it also depends on the location of the wound."

"If it's cut in a muscle, there won't be much blood, but if it's cut in a vein, the blood will gush out.

But if the artery is cut, 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 should have been knocked out of the head by the murderer without any precautions."

"If Huang Zhiqiang and He Liqiang have this kind of medium-speed splatter blood on their bodies, then it is easy to determine who the murderer is?"

"Plus, as long as you find out who is left-handed, you can basically pinpoint the murderer."

"Hmm." Listening to Lu Weiwei's analysis here, 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 bloodstains were still there.

Even if the two hold their own, the evidence often lies in the details.

No matter how much the two lie, as long as these clues match, the murderer can be identified.

"Then what are you waiting for? Let Lao Ding, Wu Xiaofeng and Ji Zhe help us make sure whether there is such blood on these two guys?"

"Also, looking at who is left-handed, there is basically no way to run."

"Wait a minute." Officer Wang's voice fell, but 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 the matter, Junior Brother Gu? Haven't the clues been found?"

"Although we found a clue, but..." Gu Chen frowned, and there was a hint of fear in his eyes.

...
