After a long period of sorting, the first-instance verdict in front of Mori Kogoro and them looked like this. Offender: Hakamata Yan, former professional boxer (29 years old at the time of the crime)

Victims: The family of the executive director (42 years old), who were killed in the order of being the special manager of blood type A, the wife of blood type B, the son of blood type AB and the daughter of blood type O

Motive for killing: greedy for the money of the special minister

Killing: In order to steal property, he wears five pieces of clothing and a rainproof jacket, and carries a carpentry knife into the miso factory. He then climbed up the tree at the back door of the shogun's house, jumped over the Tokaido railroad fence that blocked him and jumped into the shogun's house. After assassinating a family of four and slashing more than 40 times, he stole three wallets, returned to the factory through the backyard door, took off five pieces of clothing and changed into pajamas, and waited for the opportunity to throw five pieces of clothing into the brewing barrels of the miso factory to destroy the evidence. Subsequently, he took the mixed oil from the oil tank at the factory, set fire to the bodies of the four people and returned to the factory.

"Although it is said that confession investigation letters are generally things for the murderer to confess his crimes, ......" Kogoro Mori shook his head with a wry smile. I've never seen anything like that. ”

"There are a total of 45 confession letters from the prisoner, and 44 of them are found unusable?" Mao Lilan looked at his father's sketched notes and exclaimed. "How so?"

"Of the 45 confession investigations, 17 were confession investigations produced by prosecutors, and all but the oldest one were made after the lawsuit was filed on September 10," Mori Kogoro is obviously familiar with these things, probably due to the influence of Fei Yingli's previous training. "Article 31 of the Constitution and Article 197 of the Code of Criminal Procedure strictly prohibit an investigation after an indictment, and a confessional inquiry made after the indictment is naturally considered invalid."

"As for the 28 police confession investigations...... You also know that under the influence of public opinion, the pressure on the police is very high," Kogoro Mori said with a wry smile. "In the process, they apparently subjected Hakamata to a high-intensity interrogation, or rather...... exerts a coercive and deterrent influence on the defendant's discretionary decision, and therefore does not possess the 'arbitrariness' required to be admissible as evidence"

"That is, 44 out of 45 confessions are problematic, and the judges still have trust in the remaining confessions?" Mao Lilan was surprised. "If there's a problem with a confession, the rest should be seriously considered whether it's trustworthy, right?"

"There can only be one bed bug in the noodles. (The concept of American evidence law, if there is a problem of falsification of key evidence in the evidence chain, then all evidence will be invalidated, in order to avoid the situation of falsification of evidence by the police)" Conan expressed Maoliland's point of view in the classic American narrative. "But Sister Xiaolan, the prosecutor and the police are not together, no matter what the police's confession is, the prosecutor's confession is invalid only because the procedure is unconstitutional, not because the prosecutor has unfriendly behavior, so the confession investigation before the indictment is considered valid."

At this moment, Maori Kogoro suddenly frowned. "This ...... What's going on? ”

In his hand, he was holding the first confession investigation produced by the police on September 6 - as a criminal police officer, Mori Kogoro knew that if even the court expressed dissatisfaction with the production of the confession investigation, I am afraid that the situation would be quite serious.

In fact, Kogoro Mori is not unable to understand the purpose of high-intensity interrogation: compared to the problem of unjust, false and wrongful convictions that most people fear, high-intensity interrogation can pry open the mouth of a prisoner who refuses to confess, effectively completing the entire closed loop of the evidence chain, and the facts have proved that this solution can directly solve all problems in most cases and ensure that there are no unjust, false and wrongful convictions.

However, if Yingli is dissatisfied with this, I am afraid that it is not a problem of procedural justice, but a problematic confession extorted by torture. That's why he goes to see the first confession trial, and after reading this, he goes to the last confession investigation.

But on the first confession inquiry, he saw the problem, because the content of this confession trial was too weird.

First of all, in the first confession investigation, Hakamata Yan confessed that he was wearing pajamas when he killed the people, and his motive for killing was "having an illicit relationship with the wife of the special manager, and the wife hoped that Hakamata Yan could help him burn down their room so that he could build a new house." ”

Secondly, in the first confession investigation, Hakamata claimed that he was wearing pajamas at the time of the crime, and that he put on a rainproof jacket outside (it was a sunny day) in order not to be conspicuous, and finally claimed that his pajamas were stained with blood when he killed someone, and he was finally forced to wash the clothes.

However, in the first-instance verdict, the court found that Hakamata Yan was wearing a set of "five clothes" that was discovered later when he killed him, and only changed into a set of pajamas for unknown reasons after the murder and returned to the factory, and then set fire to the special manager's family - this is really a bit strange, and it also completely refuted Hakamata Yan's first confession.

In this way, Mori Kogoro can indeed understand his wife - such a strange confession investigation content, and the equally strange first-instance verdict, does make people feel quite strange.

Of course, it is not advisable to conclude that such a move is strange and that it is not true, but again, it is even more absurd to assume that such a move is a fact. Considering that Fei Yingli's position is that of the defense and not the prosecution, this statement in the first-instance verdict is quite fragile.

"By the way, what does a carpentry knife look like?" At this moment, Conan suddenly asked such a question to Mori Kogoro.

"Carpentry knives?" Mori Kogoro was stunned for a moment before replying. "That...... It's the kind of knife with a round handle, which is similar to a fruit knife. ”

"The first-instance verdict said that Hakamata Yan used such a knife to carry out his murder plan, and used such a knife to slash four people more than 40 times," Conan said, holding his chest. "Even if Hakamata is a boxer, is it unreasonable that he chose to use such a knife to carry out premeditated murder?"

"Professional boxers shouldn't need this kind of thing at all," Kogoro Mori also frowned. "More than forty dollars...... If you use your fists, maybe seven or eight punches can make two big, two small and four normal people lose the ability to resist, why waste more than forty knives of time on them? ”
