"Definitely! It was indeed Chizo Ogura, and everyone stayed away from the washstand, waiting for the gas masks to arrive at the initial point where they were investigating the chlorine production. ”

Miwako Sato beckoned for an evidence bag, put the human skin mask inside, and then took a picture of Chizo Ogura's face with her mobile phone, and sent it to Officer Twilight.

"Takagi, you go check the surveillance and see who has been to the toilet." Miwako Sato instructed Wataru Takagi, then turned to see the crowd of people around, frowning to drive them out.

"Officer Sato, I've been here to wash my hands before, and I found that the hand sanitizer seems to be disinfectant." Conan hurriedly raised his little hand and said, drawing Miwako Sato's attention back.

"Sanitizer?" Miwako Sato repeated it again, looking at the two bottles of hand sanitizer placed together at the sink, feeling a little strange in her heart.

"Yes, it's disinfectant, and it has a pungent smell that I washed several times before I washed it off." Conan nodded affirmatively, his eyes staring straight at the two bottles of hand sanitizer on the sink.

If the guess is correct, it is these two bottles of hand sanitizer that killed Chizo Ogura.

"Officer Sato, we checked the surveillance and found that the surveillance in the toilet corridor has been damaged, but the surveillance that entered the toilet at the corner is still functioning." Wataru Takagi ran to Miwako Sato's side and quickly said the point.

"Since the venue, there have been more than a dozen guests who have entered the bathroom, but only three people have gone to the bathroom after the death of Qiaomun Gangdo. One is Conan, the other is Chizo Ogura himself, and the other is a cleaner with tight packaging. ”

"And from the surveillance, it can be seen that the cleaner's right hand has been in his pocket at the time, and it seems to be carrying something." Wataru Takagi handed the surveillance footage taken by his mobile phone to Miwako Sato, and at the same time used it to zoom in so that she could see the somewhat bulging right pocket.

Miwako Sato carefully looked through the dozen or so pictures taken by Wataru Takagi, and the pockets of the other guests were normal, only the right pocket of the cleaner was bulging, which looked very suspicious.

And among the dozen or so people who have been to the toilet, there is no new Yuan Ming.

Miwako Sato glanced vaguely at Akira Shinhara, who was probing the corpse, and breathed a sigh of relief, it seems that Officer Twilight's guess is not right.

Regarding the collusion between Akira Shinhara and drug dealers, even if it is very unlikely, as long as it is not 100%, they will go to explore the truth of Akira Shinhara.

Now it seems that Akira Shinhara is indeed innocent.

"It was indeed chlorine poisoning that caused death." Akira Shinhara took out a handkerchief to cover his mouth and nose again, bent down and looked down carefully, and came to a conclusion.

Akira Shinhara put the handkerchief on his hand, frowned and probed Chizo Ogura's pupils and nose, then looked at the condition of his neck, straightened up, and took a few steps back.

Just as he was about to put the handkerchief back in his trouser pocket, an unfamiliar police officer dressed as a waiter stepped forward to stop him, took out the evidence bag, and handed it to Akira Shinhara.

"Mr. Shinhara, after all, this touched the corpse, maybe it was contaminated with some poisonous gas, so let's leave it to us to deal with."

Shinhara took a moment, handed the handkerchief to the policeman, then spread out his palms, smelled the smell of his hands, came to the sink with some disgust, opened the faucet and rinsed the handle several times.

casually pressed the hand sanitizer next to him a few times, but found that the colorless liquid that flowed out instantly misted in the air, and there was a faint sour smell, and at the same time, there was some stinging pain on the back of his hand, almost no thought, Xin Yuan Ming quickly put his hand under the faucet to rinse.

"What's going on?" Akira Shinhara's face was stunned, with some doubts, and he was about to change the hand sanitizer again, but when he was about to press it, he was stopped by Conan shouting.

"Wait! Uncle Shinhara, don't press it! Conan hurriedly ran over, grabbed Akira Shinhara's sleeve, and dragged him into the crowd with all his might.

"What's wrong?" Akira Shinhara looked at his hands that were still dripping with water, frowned and lowered his eyes to look at Conan, and moved his hands a little uncomfortably, looking puzzled.

"Uncle Shinhara, the other hand sanitizer is filled with disinfectant!" Conan took out his small handkerchief and handed it to Akira Shinhara to wipe his hands, while eagerly explaining.

"Sanitizer?" Akira Shinhara wiped his hands for a moment, looked at his hands, lowered his head and smelled the smell, revealing a sudden expression, "So that's the case." ”

"What I used just now was hydrochloric acid, and the concentration was heavier. Luckily, I only managed to squeeze a little. Shinhara looked at the back of his hand, there was a small piece of red on it, with some stinging, shook his hand, returned the handkerchief to Conan, and thanked him.

"Is it a hand sanitizer problem?" Miwako Sato noticed the situation on Akira Shinhara's side, and hurriedly stepped forward to ask.

"Yes. Two bottles of hand sanitizer, one containing hydrochloric acid and the other with disinfectant. The main ingredient of the disinfectant solution is sodium hypochlorite, which reacts with hydrochloric acid to form chlorine gas. I think Mr. Ogura died because of this. ”

Akira Shinhara handed his hand to Miwako Sato and looked at it, and sighed, "Fortunately, the range is small, but I don't know who did this to cause panic, and Mr. Ogura became this unlucky guy." ”

Miwako Sato shook her head in confusion, and asked the forensic officer to carefully pack the two bottles of hand sanitizer separately, take them back to the police station to check fingerprints, and at the same time Takagi Wabu went to find the cleaner who was in charge of cleaning the toilet today, and soon got a bad news.

"Officer Sato, we found out that the cleaner who was on duty today was at home on leave and did not come, and the one who came today is said to have come to take his place."

"But we checked her details, she received a large transfer from the secretary of the Tianfu Hotel a few days ago, and now it has disappeared, and the police are tracking it."

"It's very likely that this was an indiscriminate murder in order to affect the reputation of the Rice Flower Hotel, after all, they have always been at home."

Based on the existing clues, Wataru Takagi made inferences and guesses, with some sighs, as if he felt that it was a trick of fate.

"The time she was waiting for may be when the guests relax and go to the toilet after the case is over, so as to ruin the reputation of the Rice Flower Hotel, but she didn't expect Chizo Ogura to go to the toilet early."

Conan frowned and listened to Wataru Takagi's inference, touching his chin with one hand, and always felt a little strange in his heart.

Is that really the case?

Was it really a malicious and purposeless murder case, or was it just a murder case against Chizo Ogura personally?

Just a simple business battle between two restaurants? However, the Rice Flower Hotel has already committed a murder today, and it is no longer meaningful to do it again.

Officer Takagi was right, if the evidence collection was over and everyone present was free, anyone could go to the bathroom and become the first unlucky person to die.

But why did Chizo Ogura go to the bathroom at that time?

Conan was shocked in his heart, and the words that Shinhara Akira had said before sounded in his mind, and he looked at Shinhara Akira, who was looking down and smelling the palm of his hand, with disgust in his eyes, and seemed to be in a little unhappy, and his heart was even more suspicious.

Did he do it on purpose or by mistake?
