The little catcher in the police station

"Scientific demarcation is then made from the scope of the suspect's appearance, from the suspect's familiarity with the environment, including how fast he comes and goes, and the motive of the criminal suspect's crime. An Qibing and An Guosheng both The family has always had grudges."

"Therefore, judging from the means and targets of the crime, it is logical that this case was originally determined to be a retaliatory crime. At this point, it seems that the truth has surfaced. However, the murder weapon of this case, Where is it?"

In fact, this case is not complicated. As long as the murder weapon is found, it seems that the truth of the case will be revealed!

"I think the police provided the court with a kitchen knife as a weapon, but because the victim's blood was not collected on it, it was not recognized as a murder weapon by the court. Maybe he washed the knife clean, and the technology at that time was not Check out the blood on the knife!"

At this time, Yu Anmin remembered that he happened to see the piece about physical evidence. At that time, he felt that the previous technology was still too backward in blood stain detection. Perhaps with the current technology, blood stains washed with water could be detected!

As long as the luminol reaction proves that there is blood on the kitchen knife found from An Qibing's house, it will also play a vital role in this case.

Chapter 728 Confessions are lenient, and you will be imprisoned.

"You mean luminol solvent?"

Hearing what Yu Anmin said, Hou Fan's first reaction was to think of luminol solution.

This solution has now been widely used in criminal investigation methods, and its verification effect is very sensitive, and it can detect only one part in a million of blood.

Even if it is old blood, you can see the fluorescence after spraying it.

"I'm afraid not? Luminol also fluoresces in the presence of iron, iron-containing alloys, horseradish, or certain bleaches, and can detect animal blood. It may also be pig blood or chicken blood on the kitchen knife! "

Li Yan immediately denied this method, and then said: "In my opinion, it is better to extract the DNA from the kitchen knife for testing. After all, the current DNA technology is much better than that of the past 20 years. Maybe things that could not be extracted before can be extracted with the current technology. Accuracy, can be extracted!"

Listening to everyone's analysis, Jiang Hao nodded and shook his head.

Seeing Jiang Hao like this, Xu Danying thought he had thought of something, so she asked, "Did you also find something?"

"There is a problem with this evidence."

"something wrong?"

Everyone was instantly attracted by Jiang Hao's words, and they all cast their gazes, obviously wanting to know what's wrong.

"The police found this knife in An Qibing's kitchen. As a normal person, after killing someone, he would still wash the kitchen knife and continue to use it?"

"Um~"

"Uh~"

"This~"

They also fell into the inertia of thinking before, thinking that since the knife was found by the previous police, it might really be the murder weapon, but they were unable to lock the evidence due to the technical means at the time.

Listening to Jiang Hao now, it is really possible!

"That is to say, An Qibing thought that the knife the police found was not the real murder weapon, so he confidently accused himself of being wronged? But the real murder weapon has been hidden by him."

Hou Fan suddenly realized that this possibility is very high. Many criminal suspects now understand the law and know that they will be lenient when they confess, but they will be jailed and punished when they resist. They will go home for the New Year.

Interrogation by the police is very difficult, and the law must be enforced in a civilized manner, and torture cannot be used to extract confessions. Therefore, many criminal suspects will not cry until they see the coffin, and will not give up until they reach the Yellow River.

As long as the police do not have sufficient evidence, they will never admit that they have done it.

How familiar is this case?

In addition, 21 years have passed, and he is even more unscrupulous.

"So, you all think that this case was handled by An Qibing?"

Looking at the case files, all the evidence points to An Qibing, who is the real murderer, but the murder weapon has not been found, so Li Yan also felt strange when he heard Jiang Hao ask:

"Isn't it? No matter how you look at this case, it was done by An Qibing. It should not be fake. He just wanted to reverse the case by relying on the key evidence that the police did not have objective evidence. But in the testimony, An Guosheng's little His son, An Geng, claimed to have seen the murderer's true face, and his neighbor An Haicheng had also seen the murderer's back, and thought it was An Qibing. They were all from the same village, and they could basically recognize it at a glance who!"

In fact, at this time, Jiang Hao didn't know whether An Qibing was responsible for this case. He was just analyzing the possible loopholes in this case from an objective standpoint, not thinking that An Qibing was not responsible for this case. of.

As long as this clue is not an iron-clad fact, then everything is possible!

Therefore, Jiang Hao will not easily draw conclusions to determine whether An Qibing is the murderer.

At this time, Jiang Hao and everyone had differences in thinking about this case.

Li Yan, Hou Fan and others believed that the murderer was An Qibing, but he was cunning and hid the murder weapon and refused to explain it. Now they just need to follow the results and deduce the process.

Jiang Hao believes that although a large amount of evidence now points to An Qibing, there is no objective evidence, and subjective determination alone cannot really confirm that it is An Qibing. He needs evidence to deduce the result.

These two methods have their own advantages and disadvantages.

First of all, if the murderer is really An Qibing, it is obviously easier to deduce the result from the result, and the possibility of finding evidence is higher.

It's like doing a math problem. After all, the answer is told to you and you are asked to solve it, and you just need to solve it according to the answer. You can always use some equations to solve this difficult problem.

The downside is that once the answer is wrong, then obviously, all the solution equations are wrong, and everything will be lost!

Jiang Hao naturally knew that although their method was relatively simple, they could not ignore other possibilities, so he said:

"The testimony of the neighbor An Haicheng, at the beginning of the first testimony, he only used ambiguous words such as "look like" and "unsure", and later saw that the police locked the suspect, so in the subsequent testimony, he made up his mind to hypnotize himself. With such inconsistency in his testimony, I don't think his testimony can be regarded as a qualified testimony, and An Geng's testimony..."

That night, An Geng, An Guosheng's son, also fell into a coma after being stabbed with a knife. After more than a month of treatment, he regained consciousness, but hesitantly injured his brain, so he did not testify to the police immediately. It wasn't until half a year later that his condition improved slightly, and he revealed that the murderer he saw that night was An Qibing.

"Do you think that a 9-year-old child's words are true and effective?"

In this testimony, An Geng was the first witness at the scene, and his witness testimony, to a certain extent, basically identified the murderer as An Qibing.

"What about the motive for committing the crime?"

Li Yan seemed to want to struggle again. After all, through a lot of investigations by the police, it was found that An Qibing and An Guosheng had a long-standing grievance. After a fight, it is not ruled out that An Qibing is still angry and has thoughts of revenge in his heart.

Hearing Li Yan's question, Jiang Hao didn't know what to say for a while!

After all, based on the existing clues, it is indisputable that all the evidence points to An Qibing, otherwise the sentence would not be so severe.

In the investigation by the police, An Guosheng had never had such a big conflict with anyone, it was so big that it would kill people all over the house.

Therefore, An Qibing, who had a feud with his family, came into the police's field of vision.

"Well, let's take stock of all the physical evidence from that year, and use the latest technology if it needs to be equipped with the latest technology. If you want to use machines that we don't have in the bureau, send them to the southern province. I will call there at that time. , hurry up and make it."

Chapter 729 Look down on him, he doesn't even bother acting!

"Okay, it seems that we will enjoy the blessings of the Jiang team in the future. The evidence we sent to the southern province needs to be inspected by them. They say that they are busy now and they want us to wait. It will not be able to do it in half a month. From now on, as long as we report the name of our Team Jiang, it will be a green light all the way!"

"That's right, Captain Jiang is now a celebrity in the Southern Province, so no one can afford to lose some face!"

Seeing that the building was a bit crooked, Jiang Hao quickly stopped it: "Okay, okay, it's not as exaggerated as you say, let's do things first!"

Jiang Hao sent them to sort out the physical evidence, and he was a little confused at this time.

Is An Qibing the murderer?

This is easy to confirm, just go to him to confirm it.

If he is the murderer, then everything is easy to say, there is no controversy, even if the murder weapon cannot be found, it doesn't matter, he has already been severely punished by the law.

But what if?

As long as the case remains in doubt, anything is possible.

What if the murderer is someone else?

This is what Jiang Hao is most afraid of!

The good guy spent 21 years in prison for no reason, but the bad guy got away with it for 21 years!

What's even more frightening is that after going through the entire file, Jiang Hao didn't have any clues!

"Help me get the physical evidence photos from that year!"

Jiang Hao said to Xu Danying, who handed over a thick photo album, which contained all the photos taken about this case.

It contains all the photos that can be used as evidence at the first crime scene.

Because the photo was too bloody, Xu Danying glanced at it and turned her head away.

Just the first photo made her heart twitch!

This photo is the photo of An Lili when she died. The murderer was extremely decisive, and the wound was fatal, directly on the neck.

The entire bed sheet was covered in blood.

Most of the wounds on An Guosheng's body were concentrated on the arms, and the fatal wound was on the chest, which was almost opened. The murderer's method of committing the crime was extremely cruel.From the photo, it can be clearly seen that An Guosheng used his arm to block the knife and fought with the murderer, but...

Wife Sang Sufeng's injury was mainly on the head, open craniocerebral injury, scalp laceration, and also very serious, but fortunately, her skull was relatively hard, and after timely rescue, she was finally rescued.

From the photos one after another in the album at the back, Jiang Hao discovered that the murderer must have premeditated the crime, but he obviously did not expect to meet An Geng who woke up in the middle of the night, so he was obviously a little nervous behind.

This is how to run away in a panic!

Soon, Jiang Hao looked through all these photos, but still had no clues.

"It seems that the first task is to go to An Qibing first to confirm whether the person was killed by him!"

Thinking of this, Jiang Hao asked Xu Danying to take the police car keys and prepare to go!

"Where are you going?"

"Let's find this An Qibing and have a chat!"

According to the address, Jiang Hao and the others quickly came to Anning Village.

The village hadn't had a police car for a long time. When some old people saw the police car, they came out one after another. Obviously, they wanted to know who was so unlucky at the beginning of the new year, and the police came to the door.

Jiang Hao drove and looked out the window again and again.

I found that there is basically no popularity in the village. Most of the young people went to the city to work. Some conditions bought a house in the city, and those who did not have the conditions can also rent a house, or live in a factory, and rarely return to their hometown. , There are basically only some old people in the village.

Jiang Hao didn't know where An Qibing's home was, so he had no choice but to find the old man in the village, ready to ask.

At this time, there happened to be an old man on the side of the road. Jiang Hao slowed down the car, lowered the window, and asked, "Master, how can I get to Anqi Bingjia?"

When the uncle heard the words, he pointed his hand, and Jiang Hao knew which one it was!

"Thank you uncle!"

Arriving at the gate of An Qibing's house, Jiang Hao stopped the police car. At this time, the old people in the village suddenly realized that it was not surprising that they were looking for An Qibing.

So, the old women in twos and threes got together again and started pointing at the police car and making irresponsible remarks!

A police car came to the door, An Qibing hurried out, thinking, the Public Security Bureau still takes his case very seriously, come here, after waiting for a few days, the police will come to investigate.

It's just that when he came out and saw Jiang Hao and Xu Danying, An Qibing's face suddenly changed, and it was so dark that it was ugly in an instant!

[Sure enough, you can't trust them and arrange for two young people to come over to investigate the case?Isn't it a joke?Is there really no justice and justice in this world? 】

Jiang Hao's 'Knowing People' is very clear, and he already has the answer in his heart!

But the process still has to go, so he said:

"Hello, is this An Qibing? We are criminal police from the Serious Case Team 3 of the Mazhou Public Security Bureau. My name is Jiang Hao, and her name is Xu Danying."

An Qibing, who has been in prison for 21 years, has seen through everything a long time ago, and his face has lost his sophistication. He sneered:

"Hehe, your Public Security Bureau is really perfunctory and sent you two brats over here. Sure enough, you shouldn't have believed your nonsense back then!"

After finishing speaking, An Qibing looked at Jiang Hao and the others with a sneer on his face, obviously very disdainful in his heart, he was already broken, no matter how miserable it was, could it be worse than now?

It's just that he is completely cold-hearted about the behavior of the Public Security Bureau. Isn't it obvious that he was perfunctory by sending two such young people over to investigate the case?

Even if you don't file a case, it's better than arranging them if you arrange two people with more senior qualifications to come over to act, right?

This is obviously looking down on him, and he doesn't even bother acting!

"Why are you so rude?"

Hearing An Qibing's insulting words, Xu Danying immediately became angry. She has never seen such low-quality people. They wear uniforms anyway, and they represent the image of the country. You don't need to respect them, but you can't point your nose and say they are Little kid, huh?

"I'm a murderer, what kind of manners do I need? You don't have the skills to arrange a young man to perfuse me, why don't you tell me?"

When An Qibing saw that the little girl dared to talk back, he immediately turned back. He was also angry at this time, so naturally he would not be used to Xu Danying.

"You don't know Taishan with your eyes! Although he is young, he won the honorary title of the top ten outstanding policemen in the country last year. No matter how many people want to invite him, he can't invite him!"

"Hehe, this honorary title is too worthless!"

Seeing An Qibing's expression that the whole world owes him, Xu Danying suddenly felt that there is an old saying:

poor person must have something mean.

At this moment, Xu Danying really wanted to just throw her hands away and leave this place. She felt uncomfortable even if she stayed here for a second. The most unbearable thing for her was that the other party said brazenly: the honorary title of the top ten outstanding police officers in the country is worthless.

Jiang Hao, who has been silent on the sidelines, has been observing An Qibing through the "knowledge of people" technique. Seeing that Xu Danying's chest was bigger than usual, he motioned her to stop talking and let him handle it!
