Chapter 678: Masao's incident

　　 On April 4, Sunday, morning, Katsuo Masao, Hachioji City, Tama New Town District.
Masao Katsura’s house is a three-story one-family house. He opened the door and led Officer Sato and Officer Takagi into the room. He pointed to the stairs and said, "Officer, please go upstairs. I’ll look for it in the lobby. ." He ran towards the hall as he said.
　　 "Okay," Officer Sato said, "Let's go, Takagi." As he ran upstairs, Takagi immediately followed.
Conan also walked into the room. When he was about to follow Katsuo Masuo, he suddenly felt windy. He followed the direction and found a circular hole in the window glass. Upon closer inspection, it happened to be on the edge of the window. , Is it an outsider?
At this time, Katsuo Masuo screamed from the lobby. Officer Takagi, Officer Sato, and Conan ran to the scene together and found Katsuo Masuo sitting on the floor in front of the door, pointing forward with trembling fingers and following him. Looking in the direction she pointed, a woman was lying motionless on the ground on the right side of a bicycle-style exercise machine, with a knife stuck in her back, and her back was dyed red.
There is not much furniture in this room. Except for the Japanese-style table in the middle of the room and the cabinet by the table, it is only on the left side of the door. From the wall, there is a small one, one large and two bookshelves. The big bookshelf is less than one meter away from the bicycle type. On the left side of the exercise machine is a long platform.
　　 Officer Sato immediately ran forward to check, and Officer Takagi was going to call an ambulance.
　　 "No," Officer Sato said, "The photographer should be called."
　　 "Photographer, photographer!" The three police officers of Takagi were taken aback.
　　 Police Officer Sato scanned the hall, then said to the floor-to-ceiling curtain, "Come out, the person behind the curtain."
　　 "P..." With the applause, Oda Shine, Oda Sakurako, and Oda Haruko came out. Oda Haruko was also holding a portable video recorder.
　　 "Officer Sato, what a wonderful performance." Oda Shine smiled.
　　 "Miss Shine, why are you here?" Officer Sato asked.
"We took the order to investigate the bank robber incident on Friday." Haruko Oda said, "Your police are really untrustworthy. Under the full view of the public, just let the two gunmen run away with the money. Did not catch it."
　　 Seeing that Officer Sato's face changed, Oda Sakurako quickly stopped and said, "Haruko!"
　　 "I'm telling the truth," Haruko Oda said.
　　 took a breath and angered under the air pressure. Officer Sato asked, "I'm asking about things here. What's the matter with this dummy?"
　　 "Dummies!" The three of Officer Takagi were taken aback, and Katsuo Masao turned pale.
　　 "This is a trap set by some guy. I didn't catch the prey, so I accidentally fell into it." Oda Shine looked at Masao Katsura with a smile.
　　 "What are you talking about," Katsuo Masuo exclaimed, "Why did you show up at my house, my wife?"
　　 "Don't you understand? We were hired by the consortium behind your bank to investigate you." Haruko Oda said.
　　 "Suzuki, Suzuki Foundation!" Katsuo Masuo's sweat came down.
　　 "As for your wife, he is now being treated at Hachioji City Hospital," Oda Sakurako said.
　　 "What the is going on?" Officer Sato wanted to get the portable video recorder in Oda Haruko's hand, "Let me see what you guys are shooting."
　　 Oda Sakurako stood in front of Officer Sato, "Sorry, Officer Sato, I can't show you this."
　　 "In this way, if you have time, how about reasoning, Officer Sato, Officer Takagi?" Oda Shine smiled, "Just as Mrs. Masuo fell on the ground."
　　 "Reference?" Officer Sato said, "Okay."
　　 "Then, don't mind if I join too." The Shiratori Police Department added in.
　　 "Of course I don't mind, Shiratori police department supplemented it, no, it's the police officer," Oda Shine said with a smile, "I heard that you have been promoted to the police department, congratulations."
　　 "You're welcome." The Shiratori Police Department smiled triumphantly.
　　 "Sakurako, the one in Kyoto is already the police department, right?" Oda Haruko asked with a smile.
　　 "Cough, cough!" The Shiratori Police Department was choked with saliva.
　　At this time, Mori came in with Hattori and Yamazaki, looked at the situation in the house and asked, "Who is dead?"
　　 glanced at the camera, Yamazaki walked a few steps aside.
　　 "It should be Madam Masuo," the Shiratori police department said.
　　 "This is a dummy, Shiratori Police Department." Officer Takagi reminded.
　　 "Dummy?" The Shiratori Police Department and Maori were surprised.
　　 Officer Takagi talked about the matter, and then talked about the reasoning game.
　　 Oda Sakurako smiled and said, "Police officers, remind me that you'd better participate, especially Officer Sato and Officer Takagi."
　　 "The reasoning game?" Maori said grimly, "Then I'll go."
　　 "There will be a bonus, Mr. Mori." Haruko Oda smiled.
　　 "Ah!" Maori immediately changed his words, "This game sounds interesting, I'll join it." Then he asked, "Well, Miss Haruko, how much bonus will I get?"
　　 "It depends on how much lost gold can be recovered in the end." Oda Sakurako smiled, "The Suzuki Foundation will use the percentage as the base."
　　 "Hundred, percentage!" The gross saliva flowed down, and then quickly sucked it back, and then said, "Then let's get started. First of all, the three of you who have been wandering near Masao's house recently are the three of you."
　　 "Wrong, Mr. Mori, how could we be discovered." Haruko Oda smiled.
　　 Oda Sakurako smiled and said, "We live in three households next to him, and there is a lot of rent."
　　 "That's it." Maori said embarrassedly.
"The victim was Madam Masuo, and the murder weapon was the knife behind her. This part happened to be the back of the heart and was killed by a single blow." Officer Sato said, "I think the time of the murder was probably when Madam Masuo screamed. Said that Mrs. Masuo was attacked from behind by someone while talking on the phone."
"It should be when talking on the phone while using this exercise machine. There is no telephone landline here. She must be afraid of a sudden call during exercise, so she took the extension phone." The Shiratori police department stepped forward and looked at the exercise machine. "The record switch on the exercise machine has been turned on." Then he said, "Ms. Masao called Takagi today and said that she would go to the Metropolitan Police Department to tell about the bank robber incident, and she said to Takagi on the phone,'Yes The previous policeman', so this is a purposeful murder against Mrs. Masao, in order to prevent her from telling the police about the bank robbery, that is, the murderer should be a bank robber."
Officer Sato said: "Ms. Masuo once caught a prisoner's mask in the bank robbery incident. Although it is not clear in the video whether Mrs. Masuo saw the prisoner's face, she may know some features. For example, the mole on the mouth, so the prisoner thought that she had seen it through, so she came to kill."
　　 "No? Didn't the prisoner kill her at that time?" Maori asked.
"Because the wife of the police department Meguro who happened to be there, Madam Meguro watched Mrs. Masao's resistance and was afraid that the gangsters would attack her, so she took the initiative to replace her." The police department Shiratori said, "The gangster may be afraid of killing the hostages. The nature of the incident changed, so I didn't start it, but started it afterwards."
"But, isn't this very strange?" Officer Takagi asked, "Since it was aimed at Mrs. Masuo, when did the gangster come? If they came before the call, then they should do it before. If After that, how do you know that she is on the phone with the police?"
"It's very simple. The murderer went to other rooms to confirm that only Madam Masuo was in this room, and then came back to attack Madam Masuo," Maori said, "At that time, Madam Masuo was on the phone. As for the content of the conversation. , I think if the lobby is open, it can be heard in other rooms nearby." Then he said to Oda Shine, "Is that so? When Mrs. Masao was cycling on the phone, the murderer came in and sneaked over to her. Killed her behind him."
　　 "Good guess," Oda Shine said with a smile, "but in fact, please read the large bookshelf behind the exercise machine."
"Bookshelves?" The Shiratori Police Department opened the curtains of the bookshelves and found that the inside was empty with only a few brackets, and then found red, blood-like traces on the top frame, so he asked uncertainly, " this is?"
　　 Oda Nobue said, "Don't doubt, it is really Madam Masuo's blood, and it was definitely not painted by us."
　　 "Let me see, please." Hattori took a look, then opened the small bookshelf next to it, and found that it was full of books.
　　 "Hold me and look at it." Conan said to Hattori.
　　 "Okay." Hattori picked up Conan, showed him the top of the large bookshelf, and asked, "How about it, is there that thing?"
　　 Looking at the blood-stained piece of adhesive tape and the few thumbtacks on it, Conan laughed, "Yes, it's there."
　　 "What are you doing?" Maori asked, "What's on it?"
"I have always been surprised that Mr. Masao should have seen this dummy when he came in. No, this remains." Hattori laughed, "but why didn't he make a sound? Because he wanted to change the scene." Then he opened it. The cabinet under the long platform revealed a mess of books.
"Could it be that these books were originally on the bookshelf?" The Shiratori police department picked up a book and found some blood stains on it. "It turns out that, if I'm not mistaken, the bookshelf turned out to be on the ground and pressed against this. Dummy, no, from the corpse. These books were too late to be placed on the shelf, so they were stuffed into the cabinet."
　　 Mori said, "In other words, Mr. Masuo, you helped him up, so you are the murderer."
　　 "Ah! Mr. Mori, the murderer might also lift this bookshelf up and walk away, in order to confuse the police." Haruko Oda smiled, "Mr. Masuo was just frightened and lost."
　　 "Okay, Haruko." Oda Sakurako stopped.
　　 Police Officer Sato asked, "Miss Nobue, stop going around, what is going on?"
　　 "I'm sorry," Oda Nobue said, "This reasoning game, other people do not need to play, but you and Officer Takagi must play it. The reason, when you go back, Manager Matsumoto will tell you."
　　 "Manager Matsumoto!" Officer Sato and Officer Takagi were taken aback.
　　 "Well, two people, please continue reasoning." Oda Nobue said. "One more reminder, please treat this as a real scene."
　　 Seeing that Officer Sato and Officer Takagi had no breakthrough for a while, Conan reminded: "Hey, why is this knife horizontal?"
　　 "It goes without saying that there are bones on the back. This kind of knife can only be pierced in this part, and it can kill people." The Shiratori police department said.
"Wait," said Officer Takagi, "if the knife is sideways, and if the bookshelf is lying on the body, is that possible?" He put the books in the cabinet on the top layer of the bookshelf, and then I took out a few thin ones and exchanged some thick ones, so that the books in the bookshelf were stretched, and then pulled out the knife from the dummy and stuffed it in the gap between the top of the book and the frame of the bookshelf.
"Are you kidding? How do you kill people like this? Huh? Wait," the Shiratori Police Department said, touching his chin. "If the bookshelf falls down and gets stuck on someone, it might be possible to kill someone." Then he asked, "What? Let the bookshelf fall down?"
"The answer should be above." Officer Sato moved a chair over and stood up and looked at the top of the bookshelf. "This is tape and thumbtacks." Then he jumped down, "Then the line should be here." Next to the exercise machine, he pulled out a knotted fishing line from the shaft and pulled it onto the bookshelf. "In this case, as long as Mrs. Masao steps on the exercise machine, he can pull the bookshelf down and insert the knife into her own. Body."
"But this is not right," said the Shiratori Police Department. "Although there is a bookcase full of books next to that bookcase, it won't fall in other directions, but the more you step on the car, the harder you will find the victim. ."
"This kind of sports car has a lot of resistance, and when the thread is rolled in, the resistance is even greater, and this kind of movement generally maintains a constant speed, so when Mrs. Masao is distracted to call, she will still subconsciously force to maintain a constant speed. , So that he finally pulled down the bookshelf behind him." Officer Sato said, "In other words, the person who called to distract Mrs. Masuo is Mr. Masuo. You are the creator of the incident."
　　 "Hey, hello, Madam Masao is not blind, how can you not see such a long fishing line?" Maori asked, "And the knife can be seen there, right?"
　　 "What about adding this?" Conan took out a sign in the cabinet, which said "Target 2 kg".
　　 "By the way, if you put this on top of the knife," the Shiratori Police Department put the sign above the knife, "If you don't pay attention, you won't see the knife at all."
　　 Police Officer Takagi smiled and said, "And Mrs. Masuo is probably highly myopic."
　　 "And I don't like to wear glasses to do sports, so as not to drip sweat." Officer Sato laughed.
　　 "That's the case," said Mori, "then the culprit in this incident must be Mr. Masuo. He understands Mrs. Masuo."
"So, the whole incident should be like this." The Shiratori police department said, "After Mr. Masao set up the trap, he went to the Metropolitan Police Department to call and make an alibi, and then he came back to change the scene. Even though other policemen arrived first. At the scene, if you see the bookshelves and books falling on the ground, it can be easily explained as a dispute between the prisoner and the victim. The tape and thumbtacks can also be understood as being prepared for weight loss brands, but the fishing line must be recycled, so you Sato and Takagi were distracted when they came."
"After you pry out the thumbtack and take out the fishing line, put the thumbtack back in place. During this process, the tool for prying the thumbtack must be stained with blood." The Shiratori Police Department looked in the cabinet under the long platform and found it in the corner. A small screwdriver was found inside, "it seems to be this."
　　 "You, how do you prove that I have used it." Masao Katsuo exclaimed.
　　 Maori smiled and said, "Although we can't prove that you have used it, someone can."
　　 Looking at the camcorder in Haruko Oda's hand, Katsuo Masuo was instantly discouraged.
　　 Shiratori Police Department asked, "Then, Mr. Masao, why are you killing your wife?"
　　 Katsuo Masao said, "For and for the insurance money, I bought a high amount of insurance money for her, so I used the bank robbery to give my wife to..."
"Please, you lie too badly." Hattori smiled. "Your wife must have found out who the bank robber is and has something to do with you, so I blackmailed you. The reason why I changed the hostage back then Not because of fierce resistance, but because she is the mastermind’s wife."
"That's it," Maori smiled. "The bank manager and his friend joined forces to rob their bank shop. Of course, the plan will go smoothly, but unfortunately, your friend will happen to go to the bank while the plan is on. Taken hostage, it’s even more unfortunate that your wife recognized your friend~EbookFREE.me~ so she dared to resist fiercely."
　　 "It seems that this is correct." The Shiratori police department said, and then asked, "Mr. Masao, why did you rob the bank shop you manage?"
"Sigh." Katsuo Masuo sighed, "It's not because of the need for money, it's all forced by Kadai, I'm just the store manager, I'm just managing the bank shop, but she thought I opened a bank and splurge. But to satisfy her. I used to use my power to do some private work. After she knew it, she became even more presumptuous. This time she blackmailed me again, so I planned to kill her."
　　 "That's it," the Shiratori Police Department said.
　　 Katsuo Masao said to Oda Shine, "Can you tell me what happened? Why didn't Kayo die? You know, I did a lot of experiments, and I was sure that it could be killed in one shot."
　　 Police Officer Sato said: "Miss Nobue, the matter is resolved now, can you tell me why I want to participate in this reasoning game."
　　 "The incident is resolved, but please wait a moment." Oda Shine smiled wryly.
　　 "What the are you doing?" Officer Sato asked.
　　 "Testing a new technology," Oda Sakurako said, "transmit the image here wirelessly to a distance."
　　 "Uh, the distance you are talking about is not the Matsumoto Superintendent of the Metropolitan Police Department, right?" Officer Takagi asked.
　　 "It would be nice if it could be that far." Haruko Oda sighed.
　　 "It's nearby." Oda Nobue said, "but I will give it to the Matsumoto manager later."...
