This was the first battle between the prosecution and Cao Yun. Is Yezi dead? Cao Yun raised his own question, and then the prosecution needs to answer this question. Officer Sun has nothing to do, the evidence he gave is ironclad, and Cao Yun will not find a breakthrough from this evidence itself.

The prosecution was a man in his 40s, who was very experienced, and he invited the first witness to the court, and the first witness was a forensic doctor, a woman in her thirties, who was not beautiful. It can be seen that the prosecution is ready to raise this question and fire at this position, and has prepared witnesses in advance. This shows the difference between the competence of prosecutors and prosecutors.

The prosecutor walked over to the witness stand and said, "Witness Mingzi, please explain your identity." ”

Akiko replied, "I am Akiko, a staff member of the forensic science classroom at Dongtang University, and I am also the forensic doctor in charge of the murder of Noko. ”

Forensic medicine has a very low traditional status in the Eastern Tang Dynasty, and it is also known as 7K, dangerous, dirty, tired, harsh, no vacation, no makeup, and no marriage. All of these words begin with K in Japanese pronunciation. The forensic medicine of the Eastern Tang Dynasty was a neutral academic or commercial institution, the forensic dissection was handled by the forensic science classroom of the university, and the administrative autopsy was carried out by specialized hospital physicians. Whether or not he killed is a matter for the medical examiner, the police or the prosecutor in charge to make a decision.

Although the country to which Dongtang belongs is a developed country, it lags far behind other developed countries in terms of forensic level. Less than 10 per cent of the bodies of people who died of unnatural causes in the Eastern Tang Dynasty will be autopsied, a figure of 90 per cent in Sweden and 50 per cent in the UK. There have also been many cases in Dongtang where the deceased's family suspected the police's conclusion that the normal death was normal, and after autopsies at their own expense, it was found that external forces caused the death.

The traditional concept restricts the development of the profession to a certain extent, and it is not something that can be solved in ten or eight years, especially when forensic medicine is not a rigid demand, and it is by no means the first choice for people to choose a career. However, for many reasons, the salary of forensic doctors in Dongtang is at the middle and upper level.

Akiko began to explain: "First of all, judging from the bloodstains in the living room, please look at the bloodstains. The living room was cleaned up. Yezi had applied for accident insurance ten days ago, went to the hospital for a physical examination, and according to his blood concentration, we calculated and analyzed that there was about 800 to 1,200 milliliters of Noko's blood in the living room, which accounted for 22% of his total blood volume according to Noko's weight. The magnitude of the blood loss is indicative of the severity of the injury. However, there is no record of any medical treatment for Noko. It can be responsibly said that the loss of so much blood in a person is not fatal, but the wound that leads to the loss of so much blood is fatal, and in the absence of medical records, the wild child will definitely die. ”

Cao Yun raised his hand, and it was still time for the prosecution to ask questions, but in order to clarify the context of the matter, considering that the jury may not all be smart people, Cao Yun could insert questions after the judge allowed it, and did not need to ask questions after the other party's prosecution finished asking. At the same time, Cao Yun was also asked not to ask additional questions, but only to ask questions about the question explained by the witness.

The judge agreed, and Cao Yun stood up and asked, "Hello witness, since it has been cleaned up, why do you know the scope of the blood?"

"We use luminol reagents...... (omitted). ”

"You mean, blood is such a wide range. ”

"That's right. ”

Cao Yun asked, "Can you guarantee that it is 100% pure blood? I mean, if there is a liquid such as water in the blood, you still have such a large range of blood, right?"

Akiko replied: "Yes, it cannot be guaranteed to be pure blood, and external forces are not excluded." For example, when a corpse is moved, blood drips and is washed with clean water, which can cause a luminol reaction in the area. ”

Cao Yun said: "That is to say, in the case of pure blood, there are eight hundred to one thousand two hundred milliliters of wild blood in the living room. But forensic medicine cannot guarantee that it is pure blood. ”

Akiko replied, "The site has been cleaned, yes, there is no guarantee." ”

Cao Yun said: "Suppose I cut my hand and bleed ten milliliters of blood, I wash the wound with the basin, and accidentally hit the basin on the ground, the range of water in the basin can detect my blood residue, right?"

Akiko nodded: "Strictly speaking, there won't be all of them, but a large area of blood residue can definitely be detected." ”

Cao Yun faced the jury: "So, this evidence can't prove that Yezi is dead." ”

When Cao Yun finished questioning, the prosecutor was not in a hurry, stood up, and said, "Witness Mingzi, have you considered the possibility of what the defense lawyer said before?"

Akiko replied, "Yes, but based on the full search, as well as the finger situation, we tend to think that the living room is pure blood. ”

Cao Yun: "Objection, the witness has just explained that there is no guarantee that it is pure blood. ”

Judge: "The objection is valid, the witness you are a professional, you must clearly express the issues you want to explain." ”

Akiko nodded: "I'm sorry, it's the first time I've been to such a court, and I'm a little nervous...... First of all, we will explain the lower finger, which is the finger of Noko found in the sewer. ”

Severed fingers appear on the slide.

Mingzi said: "According to our comprehensive examination and analysis of the severed finger, it is determined that the severed finger was in a state of severe ischemia to death before leaving the body. Before the finger is cut off, it is at least in a state of extreme ischemia. However, because the finger has been soaked in water for a long time, it is not possible to say exactly in what state the finger was removed. According to the comprehensive search of the third section of the search, only three places with blood stains were found in the whole house, so we believe that the blood in the living room is pure blood. ”

"The objections, the witnesses are speculative. ”

"The objection is valid, and the jury can use the testimony as a reference, but not on the basis of the testimony. ”

The prosecutor nodded and continued to ask: "Witness, judging from your professional knowledge, the finger was in a state of minimum ischemia at that time, is it possible that such a person still has the strength to cut off his finger at one time?"

Mingzi said: "Impossible, there is a bone in the place of the severed finger, to be precise, it is not cut off, it is cut off." ”

The prosecutor slashed: "So?"

"Yes. ”

Prosecutor: "Since it is unlikely that the finger was cut off by Noko herself, it can only be that when the murderer dismembered the body, he accidentally cut his finger and the finger jumped into the sewer." If it's cut......"

Cao Yun: "Against the prosecution's speculation, there is no evidence for its speculation. ”

"The opposition is valid. ”

Cao Yun sat down, knowing that this prosecutor was not easy to handle. The fact that the objection is valid does not mean that the jury did not hear the prosecutor's explanation.

The prosecutor continued to ask: "Witness, with your professional knowledge, assuming that this finger was accidentally cut off by Noko himself, does an ordinary person have the ability to stop bleeding and give first aid, or will he die?"

Akiko replied, "Judging by the scars of the severed finger, it will cause a lot of bleeding after the severed finger, but it will not lead to death. If not bandaged and treated in a timely manner, hemorrhagic shock is likely to occur and various complications of infection. With current medical technology, the severed finger is well preserved and can be retrieved within twelve hours. ”

Cao Yun: "The witness first explained that Yezi's severed finger was cut off in a state of ischemia, and then said that there would be a lot of bleeding after the severed finger, so was there a lot of bleeding after the severed finger?"

Akiko replied, "In this case, there will be no heavy bleeding after the severed finger. ”

Cao Yun nodded with satisfaction and sat back. In this case, there will not be a lot of bleeding, which means that Yezi does not need medical attention.
