Seeing Tang Ze's signal, everyone who had been surrounding the sink approached the top of the water glass.
"Eh!? The coin that cannot be seen from the side can actually be seen from the top?" Officer Megure looked at this scene and couldn't help but be surprised.
"Yes, if you look at the junction of air and water from a position with a relatively small incident angle, it will not appear as a mirror."
Saying this, Sera Masumi smiled and stretched out her hand to indicate: "But this is a swimming pool, there is no angle to see it from directly above."
"That's true." Officer Megure nodded.
"The criminal's method is actually obvious at this point."
Tangze said: "The murderer first drowned and killed Miss Yongmei, who was alone here looking for the necklace.
Then use the sink prepared in advance to cover the body that sank to the bottom of the swimming pool.
After that, use fishing lines tied to the drainage holes on both sides of the swimming pool to fix the sink to prevent the sink from breaking away from the body in the water.
After that, the murderer only needs to tilt the tank slightly, then reach into the tank, and use the oxygen cylinder carried by the deceased to release air to fill the tank with air, and the trick is completed."
"The fishing line is stretchable, so it's not difficult to tilt the water tank slightly to open it."
"I already know the method, but there is still one problem that remains unresolved."
After hearing this, Officer Megure first agreed with the murderer's method, then paused and said, "Then how did the prisoner let Miss Yumi drown?"
"it's actually really easy."
Tang Ze smiled when he heard this and said, "As long as Miss Yongmei, who was still in the swimming pool looking for the necklace at that time, was not wary, and then grabbed her neck from behind.
At that time, Ms. Yongmei was always looking for things with her head down, so she would not be defenseless if her neck was grabbed.
Just wait until her respirator is unplugged and hold her down to prevent Ms. Yongmei from struggling to surface.
After all, Miss Youyou was carrying a heavy object like an oxygen tank, so she could easily sink.
The whole person stayed in the water and had no way to ask for help. He could only drown to death while struggling feebly.
am I right?"
Speaking of this, Karasawa looked at Toshima Ensaku and said: "Mr. manager of this hotel, the way you drown Miss Nagamei to make her relax is to stand in the swimming pool and point in front of him and say that the necklace is there.
, we can easily kill her with a sneak attack."
""
Faced with Karasawa's correction, Toshima Enzai turned pale and remained silent, with an unnatural guilty conscience on his face.
"But is it really possible to secure a water tank with fishing line alone?"
Officer Megure on the side glanced at Toshima Ensaku, who had a gloomy and ugly face, and realized that the other party was most likely the culprit, but what was more important now was to understand the other party's criminal methods.
He didn't want to take the person back and then put him back because there were obvious loopholes in his reasoning.
So he asked Karasawa what he was concerned about: "If the water tank is filled with air from an oxygen tank, it should have a lot of buoyancy, right?
If you just use fishing line to press down from both sides, the water tank should turn over quickly, right?"
"This is actually very simple. Just cut four grooves on the bottom of the tank and thread the fishing line into them to fix the tank."
Karasawa said: "You only need to let one end of the fishing line pass through the drain outlet and hang it on the hook above. Even if it does not enter the water, it can float the tank and expose the body."
"In other words, Mr. Toshima took advantage of Miss Nagami's visit to drown her to death, and then used the same trick to deceive others."
Sera Masumi looked at Toshima Ensaku, whose expression gradually turned ferocious, and said coldly: "After everyone has searched all the places, they will cut the fishing line and let the body appear in the swimming pool to get away with it."
"But when the water tank floats to the surface, it will make a loud sound due to the air, right?" Sonoko asked another question.
"This is actually very simple. As long as you cooperate with the driver's shouting when cutting off the fishing line, wouldn't it be possible to cover up the strange sounds?"
Conan smiled and said: "After all, at that time everyone was shouting "Miss Nagami, where are you?" Even if you heard Toshima Ensaku's voice, you would not doubt it."
"But isn't the sink broken?" Oiso Hamaka questioned.
"Yes, and the place where the sink sleeps is not in the center where Yongmei was found, but at the stairs near the corner of the entrance and exit." Raito Sanomaki also followed closely.
"Yes, when did he move the sink?" Yuanzi was suddenly startled.
"If I have to talk about the timing, it would only be when Manager Toshima and Secretary Zuomaki jump out of the swimming pool and fish out Miss Nagami's body, right?"
Xiaolan hesitated and said: "But at that time, we were all watching at the scene, and the other party only held an oxygen tank in his hand, and there was no sink at all?"
"If you don't use your hands, just use your feet."
Conan said: "Just put your feet in the sink and drag the sink in the water to the corner.
After dragging the tank to the corner of the swimming pool, just use the oxygen tank to smash the entire tank.
After all, everyone's attention at that time was on Miss Yongmei's expression, and they didn't pay attention to his movements at all.
And if you smash the glass in the water, the sound will not be heard."
"However, I remember that the manager stepped on those glass shards and injured his foot." Yuanzi looked down at Yuanzi with his hands on his hips and said, "How can ordinary people do this?"
"Perhaps not under normal circumstances, but if it's a small trick to escape sin, it's nothing."
Karasawa smiled and said: "Since the sink can only be left in the swimming pool and discovered by the police, it is better to smash the sink so that it cannot restore its original shape and injure it again to reduce his suspicion."
"If it were me, I would make the same choice!"
Conan smiled and echoed: "After all, most people have inertial thinking and think that injured people will not let themselves get hurt.
If you can get away with it by doing this, then the price of getting hurt is nothing~"
"The idea you have, little devil, is really dangerous!"
When Yuanzi heard Conan's words, she couldn't help but complain: "Be careful and go astray when you grow up!"
"I'm just considering the interests from the perspective of the prisoner based on the profiling taught by my master."
When Conan heard what Sonoko said, he decisively broke his bones and pulled Tangze out to take the blame.
"Brother-in-law really taught you some dangerous knowledge." Yuanzi couldn't help but complain when he heard this, and immediately warned: "You kid, don't go astray yourself!"
"How is that possible!" Conan waved his hands in shame after hearing this: "It's definitely not possible."
"After all, the master is Tang Zejing." Xiaolan looked at Yuanzi with a smile: ""
"Brother Karasawa, this can only be considered indirect evidence at best. Do you have evidence that he committed the crime?" Officer Megure asked.
