There is also the question of why the prisoner did not replace the first knife with a second knife if it was to frame someone else. That is, wouldn't it be safer to replace your own knife with the knife of the person who wants to plant it, so that you can take it out directly? The reason is actually very simple, it is difficult to encounter the same thing as a knife, even if it is a very common kitchen knife, and the wound caused by the same knife in different strength, posture and use is also different, not to mention, the knife will also destroy the wound when it is pulled out, and when it is inserted again, if the original knife is pulled out and replaced with another knife, it will immediately be noticed by the forensic personnel that the abnormality will be discovered, which will lead to the failure of the plan to plant the stolen goods, and it is also possible to trap yourself in. Compared with this plan that will fail almost 100% and must have a high probability of bad luck, another plan with a success rate of at least 50% and a danger of definitely not more than 50% is the first choice, that is, to insert two knives in the deceased, the first knife is his own, the second knife is the person who wants to frame the blame, although he will be suspected, and he is the primary suspect object, but the target will also be unlucky, as long as there is preparation in advance, he will successfully take it out, And if you take advantage of the ignorance of the target and create a situation that is unfavorable to the target, the 50% success rate is the lowest, and the 50% danger is the most.

Thinking of this, Mori immediately became suspicious of Yuko Ikezawa, and the idea that she was unlikely to be a prisoner began to waver. What Yoko Okino thinks about Yuko Ikezawa, Mori doesn't know, but Yuko Ikezawa hates Yoko Okino. Maori is clear. This can be seen from Yuko Ikezawa's attempt to steal Yoko Okino's privacy. Yuko Ikezawa hates Yoko Okino very much. Then she has the motive to do this, Yuko Ikezawa was able to think of an almost perfect way to steal Yoko Okino's privacy, which shows that she is very smart and has the ability to do so, plus she stole the key to Sakae Yamagishi, making Yoko Okino the only person who is likely to commit the crime, thus creating a situation that is extremely unfavorable to Yoko Okino, the above three factors add up. So that Ikezawa Yuko perfectly fits all the characteristics of the prisoner in Mori's analysis above, which makes Mori really have no way not to suspect Ikezawa Yuko. In Maori's view, there is only one difficulty in Ikezawa Yuko's plan, that is, how to explain that Ikezawa Yuko has her own fingerprints on the first knife, you must know that the first knife is a murder weapon, one explanation is not good, Ikezawa Yuko can't be planted, but she traps herself, but this is too easy to explain, planting. This is Yoko Okino framing her Yuko Ikezawa. The key to Yoko Okino's house is only owned by Yoko Okino herself, so Yoko Okino has the biggest suspicion. And in order to reduce his suspicion and at the same time hit his biggest competitor, Yoko Okino killed Fujie with a kitchen knife with Yuko Ikezawa's fingerprints, and after Fujie died, he also inserted his kitchen knife into Fujie's body, so that not only can he frame Yuko Ikezawa, but also put himself in a framed position, so as to win the sympathy of everyone, after all, no murderer will take the initiative to expose himself, the second knife is Yoko Okino, which is obviously framed by Yuko Ikezawa. As for how Yoko Okino got the kitchen knife containing her fingerprints of Yuko Ikezawa, this is easier to solve, when Yuko Ikezawa chooses a kitchen knife, she will definitely touch several kitchen knives, and finally choose one, in this way, these kitchen knives are all left with fingerprints, Yoko Okino only needs to buy one, it's too simple!

If the second kitchen knife is stabbed by another person later, the possibility of simply blaming the blame is not high, and it is very likely that it is to pick yourself out. A person will stick a knife in a corpse again unless he is full of food, and it takes a lot of motivation to get a person to do such an outrageous thing, and the only explanation is that the person has discovered something extremely unfavorable to himself. The situation that is extremely unfavorable to this person, and then related to the person's behavior of inserting a knife in the deceased's body, the two factors add up, and the only reasonable explanation is that this person knew the first knife inserted in the deceased's body, or rather, the knife was owned by this person at all, but he did not know who inserted it into the deceased's body. When the police investigate the knife on the deceased's body, they will definitely be the first to suspect the owner of the knife, in order to avoid being inexplicably accused of being a murderer, and at the same time, in order to teach a lesson to the person who dares to frame himself, this person inserted a knife in the deceased again, and this knife has the fingerprints of the object of this person's suspicion, so that although this person is still the first suspect of the police, the guy who wants to frame this person will also be unlucky. As for the case of mistake, the object of this person's suspicion is actually wronged, don't worry, because if it is really wronged, the police are not eating white rice, so they can naturally investigate the truth and return it to their innocence, besides, even if they are wrong, what if they are wrong? Since this person will be suspicious of other people, it means that this person does not have the slightest good impression of the object of suspicion, and since he has no good impression of you, he deserves to be unlucky.

After Maori analyzed this, he looked at Ikezawa Yuko with more than just suspicion, it was clearly looking at the eyes of a vicious criminal. Yuko Ikezawa has the key to Yoko Okino's house, but Yoko Okino does not have the key to Yuko Ikezawa's house, which means that Yuko Ikezawa can easily obtain the kitchen knife of Yoko Okino's house, and then use this kitchen knife to kill Fujie, thus planting the blame on Yoko Okino. There is actually a question here, that is, how did Yoko Okino obtain a kitchen knife containing the fingerprints of Yuko Ikezawa, so as to clear her suspicion in turn? Does this mean that in fact, Yoko Okino has long had the idea of framing Yuko Ikezawa? It's not even just an idea, she even got the key to Yuko Ikezawa's house. For this problem, Maori has not considered it at all, in his opinion, how could the innocent and lovely Yoko Okino have the intention of framing others? So the fingerprints of Yuko Ikezawa on the second kitchen knife are just a coincidence, a coincidence......

"Mr. Maori is right, the two kitchen knives on the deceased's body, the upper one is fatal, because this kitchen knife accurately pierced the deceased's heart and killed with one blow, as for the second kitchen knife, it was stabbed after the deceased's death, and when this knife pierced, it did not stab deeply, nor did it hurt the internal organs, which was definitely not enough to cause death." The middle-aged connoisseur withdrew the strange look that looked at Yuko Ikezawa and said to Mori with admiration. (To be continued......)
