Conan Mobile Toilet Murder Case

The mobile toilet murder case in Detective Conan appears in Episode 798 of the overseas split version of the TV series. The suspects are not just Kyogoku Makoto, and Kyogoku Makoto is not the perpetrator of this case. Here is a detailed introduction to the case:

Case Background and Scene

This case occurs in a specific situation, with the scene set in a mobile toilet. The mobile toilet itself has the characteristics of being relatively enclosed and having limited space, which provides certain conditions for the perpetrator to carry out the criminal plan. Under specific weather conditions, that is, when it is raining, the perpetrator takes advantage of the environmental factors around the mobile toilet and the structural features of the toilet itself to plan the crime.

Perpetrator's Modus Operandi

• Blocking the Drain: The perpetrator first blocks the drain outside the toilet. When it rains, the accumulated water cannot drain normally and gradually rises, creating conditions for the subsequent criminal steps. This seemingly simple act is the crucial starting point of the entire criminal plan. It changes the water flow around the toilet, putting the interior of the toilet at risk of being flooded.
• Stunning the Victim: The perpetrator uses a stun gun to stun the victim and then places the victim inside the toilet. At this time, the victim is in an unconscious state and unable to react to the impending danger, providing convenience for the perpetrator to further commit the crime.
• Arranging Burning Kerosene: The perpetrator places a large amount of burning kerosene on the shelf above the toilet, then closes the toilet door and seals the door缝隙 (door cracks) with tape, leaving only a small gap at the bottom. This arrangement uses a principle similar to the "candle water-sucking" experiment. The burning kerosene consumes oxygen, reducing the air pressure inside the toilet. As a result, the external water is forced into the toilet through the gap at the bottom due to atmospheric pressure.
• Causing the Victim to Drown: As water continuously pours into the toilet, the water level gradually rises, eventually causing the unconscious victim to drown. The entire criminal process is interlinked, and the perpetrator cleverly uses physical principles and the on-site environment to achieve the goal of murder.
