"Yes, that's right, Rice Flower Town." Kawakamiji repeated, "Cases can be drawn by analogy, and there is nothing new in the world."
"Have you encountered similar cases?" Kudo Shinichi asked, "No, no - if so, you wouldn't ask me this question."
"The first element of committing a crime is to achieve the goal, and the second element is convenience and feasibility." explained Kawakami.
"Therefore, fancy tricks like this should be eliminated. Of course, it may also be because I am out of touch with practice and my judgment is inaccurate - so I want to ask what the case in Yoneka Town is like."
Kudo Shinichi was speechless for a moment, Kawakami Tsumugi's questions were full of flaws from beginning to end.
Even the elements of the crime have been revealed, so why is it divorced from practice... This guy's ideas are a bit dangerous.
However, the little detective still caught the key word: "Like this method - do you already know the murderer's method?"
Kudo Shinichi's voice was loud, and Officer Duran turned his head when he heard the sound. It was obvious that he understood Japanese.
"I don't know, I just have some unreliable guesses." Kawakami replied, "Did you completely ignore my question? Forget it, let me come over. Where are you now?"
"monitoring room."
It is clear to Kawakami that large hotels like this basically have a complete monitoring system. The monitoring of the lobby on the first floor can be viewed at the hotel front desk, but a more detailed and comprehensive perspective requires going to a dedicated monitoring room.
Google does not provide a particularly specific structural diagram of this hotel. According to Kawakami's reasoning, the control room may be on the second floor, or in the room in the corridor on the left.
"Turn left on the second floor, the door marked No Entry for Non-Staff." Kudo Shinichi added, remembering that Kawakami Tsumugi didn't know the specific location.
The control room on the second floor is not difficult to find.
Kawakami opened the door, and the three huge screens on the console were divided into small squares with different pictures.
Kudo Shinichi and the others gathered around the desk on the left side of the control room, where a desktop computer was supported. The computer was playing the surveillance of the elevator entrance and stairwell on the seventh floor of the hotel.
Because there was only an empty rough wall in the field of vision without any dynamic objects, and the distance was far away, Kawakami couldn't tell how fast they were driving.
Officer Duran crossed his arms across his chest, stared at the surveillance camera attentively, and asked:
"Mr. Kawakami, you said that you already know the murderer's method of committing the crime. Can you describe it here?"
Kawakami Tsumugi did not introduce himself to the police officer. It seems that Kudo Shinichi had communicated with him to a certain extent.
"It's just some illogical guesses." The gray-haired young man said modestly, "Officer Dulan has received the basic information from the forensic team on the first floor."
"Judging from the flow of people in that corridor and the condition of the corpse, the murderer can actually commit the crime for up to five minutes, and within five minutes, it is obviously very tight to complete a series of actions such as killing and hiding the body. Therefore, we have a New ideas.”
"The murder weapon was left at the crime scene. Why? The most likely reason is that the murderer did not take away the murder weapon." Kawakami continued, "I think the sewage pipe repair room on the first floor was the first crime scene. "
"That's right!" Kudo Shinichi on the side quickly reacted, "The sewage repair room extends upward from the first floor! The sewage on each floor will be collected into this main pipe, and a repair door is opened on each floor. .
"The murderer probably first used some method to make Miss Motoshima stand in the repair room on the first floor, and then through the effect of gravity, dropped concrete blocks from the window of the repair room on a certain floor, killing Miss Motoshima."
The little detective told me the answer first.
Tsuyoshi Kawakami added:
"If this is the case, the murderer is not subject to the time limit for committing the crime. But one thing is very bizarre: how the murderer made Michiko Motoshima stay in the repair room."
"Sleeping pills and the like..." After Kudo Shinichi finished speaking, he also realized that it was unreliable.
"The blood test results haven't come out yet," Officer Duran added.
"If the murderer knocked out Michiko Motoshima first and then stuffed her into the repair room, then there's a problem." Kawakami made a gesture.
"Do you still remember the gesture of the corpse? One hand is stuffed in the pocket on the side. It does not rule out that the murderer is a person who pays attention to details, but - it is still a common problem, time, it is difficult to achieve perfection in such a short time .”
"But if the victim was conscious, it would be even more unlikely. There were no signs of struggle at the scene." Officer Duran said.
"That's why it's outrageous." Tsumugi Kawakami spread his hands very calmly, with an inexplicable air of showing off, "I even suspected it was suicide."
"If this is the level of Japanese detectives - here we go."
Officer Duran's taunting stopped abruptly. The capable police officer leaned forward slightly, narrowed his gray eyes, and paused the surveillance with the mouse.
"Someone came out of the elevator." Kudo Shinichi approached.
The hotel manager on standby jumps to the elevator's internal monitoring.
The perspective is condescending: a thin waiter stands quietly in the elevator, motionless, more like a statue.
The elevator stopped at the seventh floor and the door slowly opened. The waiter raised his head when he walked out of the door, revealing a petite and delicate face.
It’s Michiko Motoshima.
--------------------------------------------------
"This is simply—"
"Open the door for outrageous motherfuckers." Tsumugi Kawakami ate another lemon candy, "This is outrageous."
Kawakami and the others watched Michiko Motoshima walk out of the elevator door. She picked at the half-renovated wall, picked up something, and held it in her hand.
Not surprisingly, it was the murder weapon in this case.
"I didn't expect that the person who came out would be a victim." Noticing Officer Duran's gaze, Kawakami's face was full of sincerity, "I was just getting high."
"Actually, suicide is theoretically possible." Kawakami continued.
"I noticed a small detail: there is a small arc at the valve of the sewage pipe interface on the first floor, which can just fit a small concrete block."
"If the design of each layer is the same as the first layer, then when enough sewage passes through the pipe, it will cause a slight vibration in the pipe, causing the rocks above to fall. If the time is arranged properly, you can make yourself Smashed to death."
"You seem to be very confident in the victim's 'suicide' technique."
Officer Duran looked directly at Tsumugi Kawakami with sharp eyes, but the latter still looked lazy:
“Actually, I can also think of other possible situations: For example, Miss Motojima asked others to help throw the stone down;
"Maybe it wasn't suicide, she just wanted to keep the stone, and ended up providing convenience to the murderer; or maybe none of this is right, the sewage treatment room on the first floor was not the first crime scene at all..."
"Of course, there are no clues to support these inferences, Officer Duran." The gray-haired young man bit into the lemon candy and smiled habitually.
"So, I was just blowing it off."
