In the interrogation room of the Chengnan Branch, Yu Min's emotions were broken, which made the on-site interrogation suddenly interrupted.

But Gu Chen was used to this......

In Gu Chen's opinion, her husband Gao Tian defrauded the old man of money, maybe Yu Min didn't know about it, so he showed extreme shame after the police revealed it.

But there is another situation, that is, Gao Tian's fraud, in fact, Yu Min is aware, she is just pretending to act.

But even if Yu Min is acting in front of the police, Gu Chen has to give her 80 points, at least she can get an S card.

But today Gu Chen called Yu Min to the interrogation room, not to inform Gao Tian about the fraud, but to investigate the fact that Yu Min accidentally killed Gao Tian in the rainy night last night.

Two different things, one yard to one yard.

Gu Chen interrupted, "Can you tell me what happened yesterday again?"

Although Yu Min was crying, she still cooperated and said, "What happened yesterday also started with a call from my husband Gao Tian......"

is the same as Zhao Qiang told him before, Yu Min will tell how she picked up her husband last night, how she quarreled, and how Gao Tian threw out the car door.

In the end, Yu Min was afraid that something would happen to her husband, so she turned around to find her husband, and accidentally bumped into Gao Tian because of her poor vision on a rainy day, and finally explained the process of crushing Gao Tian one by one.

But this was not what Gu Chen wanted to hear, because what Yu Min said was a bit different from what he had investigated in the van.

From this point of view, Yu Min seems to have deliberately concealed part of the truth.

Seeing Gu Chen bowing his head and pondering, Yu Min said weakly, "Comrade policeman, this is what happened. ”

Gu Chen nodded silently, raised his head and stared at Yu Mindao, "I heard Officer Zhao say, you found out that you hit Gao Tian, so you immediately carried him to the back seat of the vehicle to hide from the rain, right?"

"Yes, comrade policeman, there was a thunderstorm at that time, and I hit Takada and seriously injured him, so I could only carry him to the back seat of the vehicle first, and then call the police for help. Yu Min said.

"Not necessarily, right?" Gu Chen stared at Yu Min with sharp eyes, leaned forward and said, "I also found a lot of blood stains in the passenger seat, if you carry your husband directly to the back seat of the vehicle, then you can explain to me?

"Huh?!"

Being suddenly asked by Gu Chen, Yu Min was a little caught off guard.

But soon, she calmed down again, and then she said, "Yes...... Well, when my husband wasn't dead, he put him in the passenger seat, and then he was going to drive him to the hospital. ”

"I thought that I would be able to get to the hospital in only a few dozen minutes by car, but my husband Takada kept shaking, so in order not to get worse, I had to carry my husband Takada to the back seat of the car. ”

"But then I can't drive, so I have no choice but to call the police. ”

"Then why didn't you say it before?"

Feel like this Yu Min is cheating on himself?

Zhao Qiang was suddenly a little displeased.

Considering that the perpetrator Yu Min and the victim Gao Tian are husband and wife, so they are in a human sense, Zhao Qiang still believes Yu Min's confession.

But just like that, Yu Min hasn't confessed this paragraph yet, which made Gu Chen see the joke.

Yu Min saw that Zhao Qiang was a little displeased, so he quickly lowered his head and admitted his mistake, "I thought it would be good to explain the general situation?" But I didn't expect this police officer to ask in such detail. ”

"Then if he doesn't say that a large amount of blood was found on the co-pilot, aren't you going to explain these situations clearly?" Zhao Qiang also didn't have a good airway.

Yu Min suddenly cried, "What's the difference?"

"It's a big difference. Zhao Qiang suddenly murdered her, but looking at Yu Min's delicate appearance, he couldn't bear to scold her loudly.

So Zhao Qiang lowered his tone and explained to her in a soft tone: "I said Yu Min? This is a matter of human life, and our police have the responsibility to investigate the situation." ”

"Just like you told us last night, you said that you picked up your husband Takada and went straight to the back seat of the car. ”

"But now, Officer Gu detected a large amount of blood stains in the passenger seat, and you turned to say that you first put your husband Gao Tian in the passenger seat, and said that you were going to take her husband to the hospital, and then you had no choice but to move to the back seat of the vehicle. ”

After a pause, Zhao Qiang also clasped the back of his right hand on his left palm, and the whole person said angrily, "Isn't it inconsistent when you come like this?"

"If you are not Gao Tian's wife, we will directly investigate you as a murder, and we will also give you a special case in consideration of your special relationship with the deceased Gao Tian, but you must at least explain it clearly. ”

I feel that saying this not only threw the responsibility on Yu Min's dishonesty, but also freed myself from the embarrassment of my colleagues in the Furong Branch, and also considered the difficulties for Yu Min, killing three birds with one stone.

Zhao Qiang took a deep breath and pretended to be embarrassed.

But Gu Chen didn't care about this, lying, dishonesty, and the many flaws he found in the van before, in fact, it can be seen that there is a big problem with this Yu Min.

In the face of many doubts, Yu Min may be able to argue with himself and let the evidence lean in his favor.

But the evidence doesn't lie.

What is fake is fake, and the truth cannot be concealed.

So Gu Chen said again, "I have tested your vehicle inside and out, and I have carefully checked all the blood stains in the car. ”

"But when I did that, I realized that it wasn't as simple as I had imagined. ”

"Officer Gu, what do you mean?" Yu Min didn't seem to understand.

Gu Chen didn't talk nonsense with her, on the one hand, the extracted evidence was ready to be sent to the technical department of the city bureau at any time.

On the other hand, Gu Chen also had to express his suspicions and confront Yu Min.

So Gu Chen directly raised the materials recorded by Zhao Qiang yesterday in his hand, and said, "Judging from the materials recorded by Officer Zhao yesterday, plus my internal and external inspections of the vehicle that caused the accident, there are at least a lot of doubts. ”

"Captain Gu, it's okay for you to say. Zhao Qiang looked at Gu Chen, but he was actually panicked in his heart.

After all, it is a very shameless thing for a peer to overturn his own records.

When he learned that the test results were not so simple, Zhao Qiang was also very entangled.

If it weren't for the torrential rain last night, I was too late to be tested.

If it weren't for the fact that the perpetrator and the victim were husband and wife, they would have been too careless.

It will not make the detection situation slip.

But this is not over, the most critical thing is that the deceased Gao Tian turned out to be the suspect that the criminal investigation team of the Seremban Branch has been tracking.

In this way, two things that have not intersected are entangled together, and the lax problem of his investigation of the case is exposed to his peers.

Zhao Qiang is like ending quickly at the moment, at least he feels like he is sitting on pins and needles here.

Gu Chen turned his pen in his right hand, and his eyes were like torches, "This suspicion is one, we found a large number of splattered blood droplets at the dashboard of the car, according to my preliminary investigation, there are at least more than 100 drops. ”

"100 drops?" Zhao Qiang just wanted to drink a glass of water slowly, but when Gu Chen said this, he almost choked in fright.

Gu Chen even counted how many drops of blood there were?

This damn obsessive-compulsive maniac.

Zhao Qiang's face darkened......

I feel that the colleagues of the Furong Branch are inevitably too careful in their work, right?

Gu Chen continued, "These bloodstains are all caused by medium-speed bloodstain sprays, and there is only one possibility of causing this kind of bloodstains, that is, the victim has been hit violently, or it is a knock. ”

Hearing Gu Chen's words, Yu Min's face became more and more ugly.

Gu Chen stared at Yu Min's eyes and continued, "And you told us that you just carried your husband Gao Tian to the co-pilot, so the bloodstains left behind should only be some contact bloodstains, or transfer bloodstains, and definitely not this kind of medium-speed bloodstain spray. ”

"And these blood stains will only stay on the seat, but they shouldn't stay on the dashboard, how do you explain this?"

"I ......" Yu Min just wanted to speak, but he stopped talking.

She didn't know how to answer Gu Chen's questions, at least the key to Gu Chen's questions was well-founded.

The more than 100 splatters of blood are proof of this.

Gu Chen saw that Yu Min didn't answer, so he said, "If you can't answer this, then I have a second question, that is, I am at the top of the driver's seat of the vehicle, which is the place above." ”

In order to let Yu Min understand more clearly, Gu Chen pointed to a general aspect and said, "I also found a large number of blood stains in this position above the driver's seat, and they were from left to right. ”

"I think to be able to leave this bloodstain is probably the result of the deceased's head being put on top of it and shaking and struggling violently. ”

Seeing Yu Min's face turn blue, Gu Chen said again, "But...... If you just put her husband Takada in the passenger seat, as you said, it is obviously impossible to cause this kind of bloodstain. ”

"Even if you hold it too high at the time, there will only be contact blood on the top, not the blood caused by rubbing left and right. ”

Hearing Gu Chen's words, Zhao Qiang looked shocked, "I didn't pay attention to this." ”

"There's a lot of stuff you haven't noticed. Lu Weiwei glanced at him and said with a light smile.

Judging from her own peeping into Gu Chen's large number of records on sticky notes, Lu Weiwei knew that Gu Chen had found a large number of suspicious clues on the vehicle that caused the accident.

Gu Chen saw that Yu Min still couldn't answer, and he probably knew it in his heart, so he said again, "If you still can't explain this question, then it doesn't matter, I still have a third doubt." ”

"And?" Zhao Qiang was stunned for a moment, feeling that Gu Chen's investigation was inevitably too careful, right?

It can be seen that the toolbox with some bottles and cans in the police car can indeed do some on-site detection and processing at critical moments.

Probably realizing that he was talking too loudly, Zhao Qiang quickly covered his mouth and stared at Gu Chen, expecting Gu Chen's explanation.

Gu Chen said unhurriedly, "This third suspicion is that I can see from the photo of the head of the deceased Gao Tian that he has an obvious scar near his left temple. ”

At that time, Officer Zhao thought that this was caused by a car accident, but I carefully examined the protruding screw cap of the car door, and the shape happened to be this hexagon. ”

"So it is very likely that the head of the deceased Takada was caused by a heavy impact on this screw cap. ”

"And this impact location is obviously not something that can be done by a car accident. ”

After a pause, Gu Chen said again, "If this is the case, then someone slammed the head of the deceased Gao Tian here, forming a scar. ”

When Yu Min heard Gu Chen's story, the whole person was already stunned.

She didn't know how to explain that her vehicle was an old van, and Yu Min didn't even notice the details herself.

However, Gu Chen linked the wound to the location of the vehicle and found the source of the shape of the wound.

How should I take this?

Yu Min was entangled, and she didn't know how to explain it.

Of course, this was also expected by Gu Chen.

If Yu Min thought that this was the end, then Gu Chen thought she was still too naïve.

After taking a sip of water, Gu Chen said again, "Of course, in terms of testing, we have found far more suspicious points than these. ”

"Take suspicion number four as an example, there are too many blood stains in the rear compartment, and if an injured person is normally housed and wrapped in a blanket, there should not be so many blood stains. ”

"And there were blood stains not only on the floor panel, but also on the ceiling of the car, on the sides and on the doors. ”

Looking at the people around him, Gu Chen said again, "You can imagine how a person who fainted after being injured could get blood stains on the roof of the car?"

"Yes, can this injured person bounce onto the roof of the car by himself?" Lu Weiwei also had a whim.

In everyone's opinion, this kind of thing is completely unreliable.

Gu Chen continued, "Unless the deceased was injured and rolled back and forth in the car, but he tried to sit, then tried to stand, and tried to open the car door to go out, it was possible to leave these blood stains." ”

"So if this is the case, it is also inconsistent with what you Yu Min said, are you?"

Being asked by Gu Chen, Yu Min bowed her head silently, she seemed to be looking for a hole to get into now, but at least she didn't know how to answer.

Gu Chen threw the pen on the table, lay on the seat with his hands on his chest, and continued, "There is a fifth suspicion, it was raining heavily when the crime occurred, and you said that you carried your injured husband into the car. ”

"If that were the case, there would have been a lot of rain in the car, but I didn't detect any diluted traces of rain in the blood stains found on the sunshade and roof of the car. ”

"In this way, it is to show that these blood stains were there before the deceased Takada got out of the car, and not after the so-called accident, you were afraid that Takada would get wet in the rain and carried him into the car, which is inconsistent with the situation you explained. ”

Seeing Gu Chen clasping the transcript materials with his fingers, Yu Min's body trembled.

At this moment, Yu Min's eyes were blank, like an empty corpse.

Every time Gu Chen asked a question, he was tired to deal with, or he was powerless to resist at all.

In the face of a police officer who knows how to conduct forensic examinations, once these things are put on the table as evidence, it basically announces the end of the lie.

originally thought that this was the end, but Gu Chen continued, "If you still can't explain this, then I still have a doubt here. ”

"And?"

Hearing Gu Chen's words, everyone almost spoke in unison.

The doubts about these questions are enough to make Yu Min speechless and unable to explain.

But Gu Chen still has doubts here?

Lu Weiwei, Officer Wang and Yuan Shasha were already surprised, but they felt that Gu Chen had investigated too carefully.

It can be seen that it seems to be worth spending so much time inside and outside the vehicle to do inspections before.

But Zhao Qiang was a little uneasy.

This Gu Chen was able to find out so many problems in a very short period of time, but he was negligent about the situation, and even almost neglected to detect it because the other party was husband and wife.

Thinking about it now, Zhao Qiang has the heart to die, and I feel that I want to get the transcript report back now, I don't know if it's too late?

Gu Chen smiled slightly and continued, "This sixth suspicion is that I analyzed the blood stains sprayed by using the wire drawing method and the triangle plate, and found the source of these blood stains that were not diluted by the rain. ”

"Normally, the location of the blood spray is exactly where the head of the deceased Takada was sitting on. ”

"And it took at least four blows to the head to cause so many jet points. ”

"Gu Chen. Zhao Qiang interrupted Gu Chen's words and asked him, "What do you mean...... At that time, Takada was sitting normally in the passenger seat and was hit in the head?"

"Yes. Gu Chen nodded slightly, explained, "This can be judged by using the wire pulling method and the triangle plate, which is the most basic detection method of forensics. ”

"Oooh. Feeling that what Gu Chen said was too professional, Zhao Qiang could only nod silently.

After all, he is Forensic Liu's apprentice.

It felt like it should be the end, Zhao Qiang just wanted to speak, but Gu Chen said, "There is a seventh point." ”

"And?" Zhao Qiang's eyes widened.

Gu Chen turned his head to glance at him and asked, "Senior Brother Zhao, do you have any questions?"

"I didn't ...... No. "I feel that I am suddenly out of place with Gu Chen, at least in terms of investigating the case, I am completely unable to interject.

Gu Chen didn't care about this, but continued, "This seventh suspicion is that I analyzed that there were also blood stains on the side wall of the rear compartment of the car with the help of white paper and reagents, and it was also a hand-like bloody handprint. ”

The white paper and reagents mentioned by Gu Chen are also a conventional technique in forensic testing, using white paper to stick on the side wall of the vehicle and then spray with special reagents.

After the chemical reaction occurred, the blood stains at that time were directly presented on the white paper, which was clear at a glance.

Seeing that Yu Min was dumbfounded, Gu Chen said again, "If there are also blood stains on the side wall of the back of the car, and it is also a hand-like bloody handprint, then it is even more unlikely that it was caused by Gao Tian being in a coma, and it is more like it was left by fighting and struggling with others." ”

"It's amazing. After hearing Gu Chen's story, Zhao Qiang felt that he had benefited a lot.

It turned out to be a simple vehicle that caused the accident, and Gu Chen could still find this multi-doorway.

But when Zhao Qiang finally breathed a sigh of relief, he felt that he could ask Yu Min about the specific situation according to the suspicions of these investigations.

But at this moment, Gu Chen spoke again.

"There is an eighth doubt......"

......
