When Hou Fan heard Yu Anmin say this, his first reaction was that Lumino solution was thought of.
This solution has now been widely used in criminal investigation methods. Its verification effect is very sensitive and can detect blood content of only one-millionthousandth.
Even if it is an old blood stain, you can see fluorescence when sprayed on it.
"I'm afraid it won't work? Lumino will fluoresce in the presence of iron, ferroalloy, horseradish or some bleach, and can also detect animal blood. There may also be pig blood or chicken blood on the kitchen knife!
”
Li Yan immediately denied this method and then said: "I think it's better to extract DNA tests from the kitchen knife. After all, the current DNA technology is much better than in the past twenty years. Perhaps things that could not be extracted before are now.
Technical accuracy, can be extracted!"
Listening to everyone's analysis, Jiang Hao seemed to nod and shake his head.
When Xu Danying saw Jiang Hao like this, she thought he had thought of something, so she asked: "Have you discovered something too?"
“There is a problem with this evidence.”
“Are there any problems?”
Everyone was instantly attracted by Jiang Hao's words and looked at them, obviously wanting to know what was wrong.
"This knife was found by the police in An Qibing's kitchen. As a normal person, after killing someone, will he wash the kitchen knife and continue to use it?"
"Uh~"
"Uh~"
"This~"
They had also fallen into the inertia of thinking before, believing that since the knife was found by the previous police, it was probably really a weapon of murder, but due to the technical means at that time, they could not lock in evidence.
Now that Jiang Hao said, it is really possible!
"In other words, An Qibing believed that the knife found by the police was not a real weapon of crime, so he was terrified of his wrongdoing? And the real weapon of crime had been hidden by him."
Hou Fan suddenly said with a sudden enlightenment that this possibility is very high. Many criminal suspects now also understand the law, know that they are frank and lenient, sit in prison, resist and be strict, and go home for the New Year.
The police's interrogation is very difficult, and they also need to enforce the law in a civilized manner and cannot torture confessions. Therefore, many criminal suspects do not shed tears without seeing the coffin, and do not give up until the Yellow River.
As long as the police do not obtain sufficient evidence, they will never admit that they have done it.
How familiar is this case?
In addition, twenty-one years have passed, and he has become even more unscrupulous.
"So, you all think that this case was done by An Qibing?"
Looking at the case file, all the evidence points to An Qibing, who is the real murderer, but he has never found the weapon of the crime. Therefore, when Li Yan heard Jiang Hao's question, he felt strange:
"Isn't it? No matter how you look at this case, it was done by An Qibing, and it shouldn't be fake. He just wanted to revert the case because the police did not have the key evidence of objective evidence. But in terms of personal evidence, An Guosheng's little
The son An Geng claimed that he had seen the true face of the murderer. In addition, his neighbor An Jianguo had also seen the murderer's back, thinking that it was An Qibing. They were all from the same village. They could basically recognize him at a glance when they saw the back.
who!"
In fact, at this time, Jiang Hao didn't know whether An Qibing was doing this case. He just stood on an objective standpoint and analyzed the possible loopholes in this case. He didn't think that An Qibing was doing this case.
of.
As long as this clue is not an ironic fact, everything is possible!
Therefore, Jiang Hao would not easily draw conclusions to determine whether An Qibing was the murderer.
At this time, Jiang Hao and everyone had differences in their 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. Now they just need to follow the results and derivation process.
Jiang Hao believes that although a large amount of evidence now points to An Qijian, there is no objective evidence. It is impossible to truly determine that An Qijian alone depends on subjective determination. He needs evidence to deduce the results.
Both methods have their own advantages and disadvantages.
First of all, if the murderer is really An Qijun, then it will obviously be easier to deduce the result and the possibility of finding evidence is higher.
Just like doing math problems, after all, I tell you the answer and let you solve it. You just need to solve it according to the answer. You can always use some equations to solve this difficult problem.
The disadvantage is that once the answer is wrong, then obviously, all the solutions are wrong and everything will lose!
Jiang Hao naturally knew that although their method was relatively simple, he could not ignore other possibilities, so he said:
"The testimony of neighbor An Jianguo. At the beginning, the first testimony was just ambiguous words such as looking, uncertainty, etc. Later, I saw the police locking up the suspect. Then, in the subsequent testimony, I decided to hypnotize myself and think that it was just that
He, inconsistent with the testimony before and after, I think that his testimony cannot be used as a qualified testimony, and An Geng's testimony..."
That night, An Guosheng's son An Geng fell into a coma after being cut. After more than a month of treatment, he woke up. However, hesitation hurt his brain and did not testify to the police immediately.
It was not until half a year later that his condition improved a little, and he said that the murderer he saw that night was An Qibing.
"Do you think that a 9-year-old child's words are sure that they are true or valid?"
In this witness, An Geng, as the first witness at the scene, basically determined that the murderer was An Qibian.
"What about the motive for the crime?"
Li Yan seemed to want to struggle a little longer. After all, through a large number of police investigations, it was found that An Qibing and An Guosheng had always had grudges. During that time, An Guosheng happened to report An Qibing to over-birth, and the two families fought for this.
After one fight, it was not ruled out that An Qiqi had not yet disappeared and he had the idea of revenge in his heart.
When Jiang Hao heard Li Yan’s question, he didn’t know what to say for a moment!
After all, with the existing clues, all the evidence points to An Qijun, which is indisputable, otherwise it would not have been sentenced so heavily.
During the police investigation, An Guosheng had never had such a big conflict with anyone, which was so big that he wanted to destroy the whole family.
Therefore, An Qibing, who had a holiday with his family, entered the police's vision.
"Let's do this, take a look at all the physical evidence from that year. If you need to use the latest technology, you will use the latest technology. If you want to use the machine that is not available in our bureau, you will send it to Nanzhou. I'll call there at that time.
