Conan carefully examined Bai Yu's words and found that it was indeed what he said. Even Miss Xia Zhu, who was most likely to poison, did not match the time of poisoning. And Manager Matsumoto, who was most suitable for the time of poisoning, happened to be
The person least likely to take action.
Then you have to start thinking about everything again.
The current situation must be what the murderer really wants to see. All the suspects cannot be the murderer, so they all may be the murderer.
The real way to hide yourself is not to erase your traces, but to blur the police's line of sight as much as possible and expand the scope of the investigation. As long as the police cannot clearly identify the murderer, despite suspicion, there is only insufficient evidence, and the prosecutor will not
It is impossible to prosecute him.
The melting time of the capsule is not absolute. If the murderer manipulates the capsule, the time can also be confused.
If time is not taken into account and only from the perspective of criminal motive, and Manager Matsumoto is excluded, then the possible suspects are: Miss Natsuki, who is a college classmate of the bride and the groom's ex-girlfriend. Umenomiya is suspected to be the bride's suitor.
Yuichi, and the heir to the Takasugi family, the groom Toshihiko Takasugi, who is said to have a very good relationship with the bride.
Conan raised his eyes and observed the three of them.
Looking at the motive for the crime, Xia Zhu was the most likely person to carry out the poisoning. But he still felt that something was wrong.
If the poisoning was carefully planned by Xia Zhu, and she planned to put the capsule into the tea can with the help of a straw, when she saw more than one outsider in the lounge, out of the mentality of a person who was about to commit a crime, she
She should subconsciously avoid committing the crime and choose a more suitable time when no one else is present or when only she and the victim are present.
Xia Zhu entered the lounge room with a white opaque bag. She was not afraid that her strange behavior of preparing a straw but not taking it out would attract their attention and increase the police force.
The reason for her suspicion is that she will not blindly take the risk and poison her.
There were still too few clues. Conan scratched his hair a little irritably.
At this time, a forensics officer pushed in the door with a report sheet and said to Officer Memu, "We compared the fingerprints extracted from the lemon tea can with the people present and found that the people who had touched Xia
Miss Take, Manager Matsumoto and Mr. Takasugi."
"In addition, based on the abnormal corrosion phenomenon on the tank mouth and the analysis of the residual liquid, the poison was sodium hydroxide. In a trash can in the front hall, residual powder in an empty glass bottle containing desiccant was found
This can also be confirmed.”
"Are there fingerprints on the surface of the bottle?"
"not found."
"Okay, I understand." Although this was an expected situation, Officer Megure was still a little disappointed and waved his hand to let the forensic officers go out.
"Put in sodium hydroxide?! Are you just using whatever you find?" Bai Yu's voice was almost sarcastic and ridiculing. Even though his voice was very low, Conan, who was nearest to him, heard him clearly.
"How do you say that?" Conan asked.
"If you use sodium hydroxide to poison people, you need to compete with its corrosiveness for time. After all, it will have been consumed along the way before it reaches the organs that can absorb it." Bai Yu smiled, "And the reaction effect is too great.
Obviously, it's easy to expose. If it were me, I'd rather switch to something more effective."
"Hey hey..."
"Oh, by the way." Bai Yu opened the phone interface and showed it to Conan, "Let me tell you one thing, the Takasugi family is in the paper business. Sodium hydroxide is also one of the raw materials for papermaking! If it were him, because
