The ambulance took Ding Nu to the airport, the private jet was ready, fortunately, she didn't die on the plane, and when she arrived at the airport in Bangkok, there was already an ambulance waiting. The rescue process is also a twist and turn, two kinds of pit viper serum in Thailand have a bad effect on Ding Nu, Thai snake experts judged it to be a South American viper, Bangkok has a stock of South American viper serum, and the effect is very good after use. Five and a half hours later, a phone call came from Bangkok to inform Ding Nu that her life was not in danger.

There are two flowers, one is Xu Xuan, Xu Xuan is very crazy, the death of Ding's wife has not yet been seen, and he intervened in the poisoning case of Ding's daughter. The other one is the seventh group, Fang Ling found Ding Zi, Ding Zi refused to sign, and the reason for refusing to sign was that I couldn't do this thing.

Fang Ling learned about it at Ding's house, and then learned about the specific situation through Ding's girlfriend.

Back to the seventh group, there is no need for everyone to have a meeting, Fang Ling reported: "Ding Zi and Ding Nu have almost no contact, the reason why Ding Zi's mother and Ding Hai divorced is that there are people outside Ding Hai, and she is pregnant, and the pregnant person is Ding Nu's mother, and she is pregnant with Ding Nu." Ding Zi has always felt that Ding's mother is a vixen, on the night of Ding's mother's suicide, he feasted his friends, spent all night drinking, and then went to the funeral under the pressure of his father, and asked his friends to call his mobile phone at the funeral, and the mobile phone ringtone was the largest, and the ringtone was that today was a good day. Ding Hai did not attend the funeral because he was stabbed by Ding's uncle, and the funeral was made by Ding Zi, and there was even a fight, and finally the police came to calm down. Ding Nu was naturally very angry about this, and the two could be said to be incompatible. ”

Fang Ling said: "By the way, Ding Zi heard that Ding Nu was poisoned and was being rescued, so I called a friend to ask for a black skin at night." ”

Su Cheng said: "This tells us that Ding Zi may not be the murderer." We have to unify our thinking, I think there are two possibilities, one is that Keiko is a murderer and an attempt to kill Ding Nu. One possibility is that Ding Nu is a murderer and plays a bitter trick. ”

Song Kai looked at his mobile phone and reported: "There is news from the physical evidence team that the snake venom has deteriorated a little, and the toxicity is lower than that of the poisonous snake when it was injected. The physical evidence team judged that the snake venom was all injected into Ding Nu's body, and in the absence of serum, the probability of Ding Nu's death was more than 80%. They are testing the A large serum to see the effect and make a conclusion tomorrow. I contacted University A, and they said that this viper serum is a standing serum, because their biological laboratory is studying poisonous snakes and snake venom, and the purpose is to treat cancer, and this research topic is commissioned by a domestic pharmaceutical company, and the deadline is from last year to the next year, during this period, the laboratory will not lack serum. ”

Su Cheng gave a thumbs up, Song Kai became more and more capable, while Fang Ling, on the other hand, did not make much progress.

Zoro asked: "Anyway, if it's a bitter meat trick, it's also a very risky bitter meat trick." ”

Su Cheng said: "When the conclusion is reached, we will know whether to take risks or not." ”

......

On the sixth day of the protection period, the physical evidence team produced a detailed report on the poisoning of Ding Nu, and after toxicological testing, it was assumed that all the snake venom in Ding Nu's house was injected into Ding Nu's body, and the mortality rate of Ding Nu was 100%, which was based on the fact that the doctor diagnosed snake venom at that time, and it took time for viper venom.

This time, the doctor was able to quickly conclude that it was viper venom, which had a lot to do with the fact that one of the doctors was sent to South America to volunteer, and there was a lot of chance in this part.

The physical evidence team believes that if the snake venom is 100% injected and no serum is used, Ding Nu will die of kidney failure after eight hours, and if the snake venom provided by A Da is added and injected within eight hours, Ding Nu's death may be 0%. Although this snake venom is not a local snake venom, but it has been somewhat deteriorated, although the serum provided by A University cannot effectively resist snake venom, but it can alleviate and alleviate the symptoms of poisoning, plus Ding Nu's good physical fitness and the medical conditions in the hospital, it can be carried in the past.

The conclusion given by the physical evidence team is: theoretically speaking, although this poisoning seems to be very dangerous, in fact, Ding Nu's life is not in danger. This conclusion is not presented in the report, and if it is presented in the report, then it will be sent to court, and the opposing lawyer will inevitably chase after it, and the conclusion given by the physical evidence team is only a theoretical conclusion, and no actual test has been conducted. It can only be a statement of the views of the evidence team at the meeting, not a report.

At the same time, the physical evidence team believes that the reason for the deterioration of snake venom is a relatively long period of harsh storage environment, at least more than a week in the harsh environment. Keeping snake venom is actually very simple, just have a refrigerator.

From the point of view of the physical evidence team, it is easy to conclude that this is a bitter conclusion.

After a few days of research, Su Cheng didn't see it that way: "Is the bitter meat plan necessary? We have already come to the conclusion that if Ding Nu is the employer, Ding Nu's level will not be the employer who contacts the gannet, and it should be Ding Nu's uncle who dominates everything." Is it necessary for the Ding Nu Bitter Meat Scheme? Okay, even if it is necessary, let's analyze another one, how to kill the Ding Nu. ”

Su Cheng: "After the witness protection team intervened, after the murderer used cyanide, the witness protection team has prepared first-aid medicine for cyanide poisoning, even if Ding Nu swallows cyanide, the witness protection team can rescue her." Let's analyze the characteristics of the murderer's crime, Ding Zi's mother, Ding's wife and his parents, plus Ding Nu's poisoning, all three cases used infiltration to steal and replace the originally safe drugs or items, so as to launch the assassination. Suppose that everyone here is a murderer and knows that Ding Nu will take violin lessons, and that he has the ability to set up mechanisms in the tutor, what do you think they will do?"

Zuo Luo said: "It cannot be denied that the poison needle hidden in the female slippers is a very suitable means of assassinating Dingzi. The witness protection team has already inspected the home of the personal trainer, and other assassination methods are unlikely to be effective. The witness protection team carried first-aid medicines, and cyanide poisoning was ineffective. I understand these things, but I would like to ask rhetorically, is it possible for the murderer to know the details of the witness protection team? Not only did he know that the witness protection team was all men, but he also knew that the witness protection team was carrying cyanide first aid medicine. The gannet's inner line has been eliminated by us, and even if it is not eliminated, the witness protection team is an independent unit, and even if it is the director, Deputy Director Zhang will not know the details. ”

Su Cheng asked, "What is the meaning of the bitter meat scheme?"

Zuo Luo said: "Anti-investigation, at present, we have basically ruled out the suspicion of Ding Zi, only Ding Nu and Keiko remain, if we believe in the bitter meat plan, it will increase the secret protection and investigation of Ding Nu and Ding Zi, and will no longer protect Keiko, or reduce the police force to protect Keiko." ”

Su Cheng shook his head: "This reason is a bit far-fetched. ”

Deputy Zhang said: "Su Cheng, if you have an idea in your heart, speak up boldly." ”

Su Cheng said: "I personally believe that this series of assassinations began after Ding Hai's death, and the purpose was Ding Hai's property. I think we've fallen into the trap of thinking that there will be four or three successors, and in the end there will only be one successor left with the murderer. But we overlook the fact that for each heir killed, the legacy of the killer and survivor increases considerably. According to the statistics of the Ministry of Technology, Ding Zi currently owns 45% of the assets, Ding Nu owns 25% of the assets, and Keiko owns 30% of the assets. ”

Su Cheng said: "If I am an employer, I will never let the heir be left alone, because it is too obvious, the police are likely to follow this line to investigate, one year and two years, eight years and ten years, I am still a suspect in the eyes of the police, even if I go abroad, the Interpol file will still list me as a suspect in my case." The money of the two heirs is already spent. Looking back at this case theoretically, I previously thought that the most unlikely assassination was Ding Nu, because she had the least assets, but Ding Nu was assassinated. The most likely assassin was Ding Zi, who owned 45% of his assets, but he was unharmed. ”

Su Cheng: "I asked myself, is my inference wrong? Later, I figured it out, maybe we were wrong at the beginning, and our biggest mistake was to exclude Ding Zi from the list of suspects. Assuming that Ding Zi is a suspect, it doesn't matter if he kills Keiko or Ding Nu, the money inherited is about the same, and at the same time, Ding Zi and Ding Nu, Ding Zi and the Diamond King have a deep hatred, Ding Zi and Ding's wife are also enemies, revenge plus money. Furthermore, why is the target not Keiko but Ding Nu? The reason is that Keiko's place of life has changed from Japan to City A, and the murderer's murder methods in several cases are based on being very familiar with the target. Keiko's life has changed dramatically, they need to spend a lot of energy to step on the point, and Keiko is protected by the police, and the act of stepping on the point is likely to expose their identity. ”

Su Cheng: "Only when Ding Zi is the murderer does it conform to the logic I proposed." But this assumption faces many contradictions. The first contradiction is why Ding Zi was in a hurry to kill his mother. The second contradiction is that Ding Zi and his wife have not been in contact for a long time, very little contact, and very little contact before Ding Hai's death, if there is no help from Ding Zi's wife, does Ding Zi have the ability to directly connect with the gannets without being discovered by us? After all, in this case, there is a certain connection between the employer and the murderer. We have seen that the murderer is very familiar with the victim in several actions, and it is very rare to step on the point so finely, I think someone must have betrayed the victim's information. ”

Su Cheng said: "Based on the above theory, Ding Nu's uncle does not know Ding Zi's mother, Ding wife and his parents, although Ding Nu understands, but Ding Nu's uncle is the mastermind, and Ding Nu does not know. What about Keiko? It is even more impossible to know the details of the Ding family's heir. So I decided that Ding Zi was the murderer, and of course, we had to find two contradictory answers. Before that, I suggested that I first verify the correctness of my theory and arrest Ding Zi for interrogation. I talked to the bald head about assuming that Ding Zi is the murderer, and Ding Zi will be very nervous and fragile in the case of Ding Zi's sudden transformation into a prisoner under the protection of the object, and we can easily read the information. The problem is that the evidence we have now is completely insufficient to qualify Ding Zi for arrest. ”

Deputy Zhang nodded slowly: "What you mean is to find someone to take the blame, arrest Dingzi, and interrogate to determine whether your theory is correct." If the assumption is correct, then we will dig deep into Ding Zi and solve the two contradictions that Ding Zi is the employer, and it will be possible to solve the case. If the assumption is wrong, then the suspicion of Ding Zi can be basically ruled out, and at the same time, Su Cheng's logical theory can be overturned, so as to support the validity of Zoro's theory. ”

That's what it means. ”

Deputy Zhang said: "Su Cheng, you specially invited me to participate in the meeting of your seven groups alone, and I knew that something was wrong. This method is quite quick and effective, but after playing a side game, according to the regulations, we can only ask Ding Zi to make a record or cooperate with the investigation...... Okay, since Su Cheng has this idea, I will sign the criminal detention notice. "A criminal detention notice is a way that the police can issue to forcibly control a suspect. Generally speaking, once an arrest warrant is issued, it means that the evidence is basically complete, the investigation and investigation of the case is over, and the personnel are transferred to the procuratorate for prosecution. The detention is generally three days, but if necessary, it is possible to apply for an extension to seven days, up to a maximum of 37 days.

Deputy Zhang said: "As far as what you have at the moment, it is impossible to extend it for three days at most, otherwise the lawyer team will kill us." Three days is a marginal ball, and more than three days is a crime. I don't think it's my business, right?"

Su Cheng smiled: "Go slowly." ”

Deputy Zhang got up and left.

Su Cheng watched him leave, closed the door, and said, "It is said that Deputy Zhang was scolded by the director when he first took office. ”

Song Kai understands the gossip: "Yes, according to the regulations, the deputy director must have a formal suit and face the media at any time." There is a standard dress code during work. It is also said that the director of the bureau said to Deputy Zhang: In his position, he must be subject to his contract, is it appropriate for you to take the salary of the head chef, but you are wearing the clothes of a waiter?"

Su Cheng: "Hehe, Deputy Zhang is still very talented, and he is a bit condescending to be a leader." ”

Song Kai replied: "He is tired, he has been so fortunate for more than ten years, and his wife and children have a lot of opinions about him, so he thought about changing to administrative work." ”

Zuo Luo said: "Okay, don't gossip, Bai Xue went to Deputy Zhang's office to get the criminal detention notice." ”

Bai Xue asked, "People just left, are they in too much of a hurry?"

"Just urge him, what's wrong? To be an administrator is to serve the front line. Zuo Luo waved his hand to let Bai Xue go, and said, "At present, I reserve Su Cheng's view of this logic, let's not discuss it first, and see the result." In addition, Bloody Jack says that there are two killers, the Silverwing Mage and the Rattlesnake, but in the three cases, it seems that there is only one killer. ”

Su Cheng said: "At present, we basically believe in Keiko, the reason is that these three cases must be familiar with the victims, Keiko obviously does not have this condition, even if the murderer steps on the point, it is very difficult to step on it so carefully." In the eighties, Bloody Jack killed a gang boss and his entire family, even the eldest daughter who was pregnant at the age of nineteen. After being released on medical parole, according to his confession, he trained a killer as a stand-in and collaborated on five or six cases. I didn't believe him, I didn't believe that a cold-blooded killer suddenly completely changed his professional ethics and moral code because Keiko had a few similarities with his wife. ”

Su Cheng added: "However, I know that emotions and human nature are not something that can be understood by logic. How about the bodyguards hired by Ding Shan?"
