"Let me first talk about the means of poisoning Mr. Hashimon, in fact, the murderer committed the murder in front of all of us." Shinhara's firm words caused everyone to exclaim, with disbelief.

Miwako Sato's mind turned, and she thought of something crucial, and asked, "Is it so?" ”

"That's right, it was when Mr. Ishikawa claimed to have rescued Mr. Hashimon, that he pushed the poison into Mr. Hashimon's body openly." Akira Shinhara pointed to the syringe in the medicine box.

It was when Mr. Ishikawa was injected. Conan replied at the same time.

"But we didn't find any poison in the medicine box." Wataru Takagi flipped through the medicine box and looked up at Akira Shinhara in confusion.

"Who said only poison kills?" Shinhara Akira glanced at Wataru Takagi and retorted, and was about to speak, when he heard Conan's innocent mouth.

"Could it be that Uncle Shinhara is referring to blood pressure medication? I watched on TV and said that blood pressure medication with alcohol can also be fatal! ”

"Is that so?" Takagi patted his head and suddenly realized.

"That's not right! Mr. Hashimon's body was found to be poisoned, and if he had been injected with antihypertensive drugs, he would not have been highly toxic in his body. Miwako Sato instantly overturned the assumptions of Conan and Wataru Takagi.

"The officer was right, and I think it was indeed Ishikawa Takei's idea, but after seeing Watanabe Kiyama, he decided to change his approach." Akira Shinhara nodded and affirmed Miwako Sato's conjecture, and put the blood pressure medicine and lipid lowering drugs on the table a little farther away.

Conan frowned and watched Akira Shinhara's movements, waiting for Akira Shinhara's continued explanation.

"Mr. Ishikawa accidentally learns that Mr. Watanabe also has a grudge against Mr. Hashimon and plans to poison him at a drinking party, so he replaces the plan he prepared earlier, chooses poison injection, and then blames Mr. Watanabe."

"But Uncle Shinhara, no poison was found in the medicine box." Conan stood next to Akira Shinhara, looking up at him, waiting for an explanation.

"High concentration of potassium chloride. It is also an essential medicine for lethal injection of condemned prisoners. Moreover, potassium chloride itself is not a poison, only when high concentrations of potassium chloride and potassium ions in blood and tissues are high, it will be highly toxic, and cardiac hyperdiastolic and sudden arrest will occur. ”

"What's more, Mr. Hashimon's own heart is not good." Akira Shinhara explained to everyone, glanced at Tanaka, who was struggling to write, and then glanced at Mori Kogoro, who didn't know whether he was really drunk or fake.

"However, no potassium chloride was found in the medical kit, and Mr. Ishikawa only stepped forward to treat Mr. Hashimon after he drank alcohol and fell, could it be that Mr. Ishikawa is so sure that Mr. Hashimon will fall?"

Conan continued to ask, and looked at the glass that had been detected for poison.

"That's right, of course Mr. Ishikawa knew that Mr. Hashimon would fall, and that was exactly what the two of them had planned." Akira Shinhara nodded affirmatively, looked at the top of Conan's furry head, and thought that this kid had a talent for praise.

"Mr. Ishikawa told Mr. Hashimon about what he saw Watanabe Kiyama preparing poison, and Mr. Hashimon himself was dissatisfied with Watanabe Kiyama's blackmail, so he decided to put on a show with Mr. Ishikawa and then arrest Watanabe Kiyama."

It's just that he didn't expect that the family doctor he trusted was the one who wanted his life the most. That's how naturally Mr. Ishikawa killed Mr. Hashimon. ”

Akira Shinhara walked up to Miwako Sato and asked her if she wanted the cardiac medical examination report in the evidence bag.

"Blackmail?" Conan once again asked his question very cooperatively, and although he roughly understood what was going on, he was still staring at Akira Shinhara's movements.

"Here's my guess." Akira Shinhara held up the heart test report in his hand and showed it to everyone.

"That's where my initial suspicions began. It is impossible for a heart patient to have his heart checked once every six months, but you, as a family doctor, have a heart test report from six months ago, and I was suspicious, so I went to search for what happened around the time of this report. ”

Akira Shinhara put down the report, then took out his mobile phone, which was displaying the news of the day when the report was made, and then handed the phone to Conan, who had been very active recently, to look at it, and then put it back.

Conan pursed his lips secretly, so he had to take out his mobile phone to search, and then read the title, "Chairman Xingrui has heart failure, and the nurse has been sentenced to be shot because of malicious revenge." It was January 9th, the day of the cardiac test report. ”

"That nurse is your sister, Mr. Ishikawa." Akira Shinhara looked at Ishikawa Tianjing, and saw that his eyes were already red, his lips trembled, and he was staring at himself fiercely, as if he was about to pounce and bite at any moment.

"I don't think Mr. Hashimon's heart failure was caused by the nurse's revenge, but by drinking alcohol despite the doctor's instructions during the treatment, but your sister suffered." Akira Shinhara sighed, with sincere grief on his face.

"I guess Mr. Watanabe knows the truth about this, so he's been blackmailing Mr. Hashimon with it." Akira Shinhara glanced at Watanabe Kiyama, and then turned to Ishikawa Takei.

"Less than three months after Mr. Hashimen was discharged from the hospital, he suffered a heart attack while drinking at a banquet, and it was you who rescued him by his side at that time. He trusts you very much, and takes you with him to any banquet, but he didn't expect that the nurse he casually planted was your sister. ”

Ishikawa Tianjing's facial muscles continued to tremble, and he looked at Akira Shinhara with bloodshot eyes, and his voice was hoarse and he didn't speak.

"Actually, at that time, you wanted to kill him, but you didn't expect his luck to be extremely good, and he was not selected by the death needle, but saved him by mistake."

"So, when the first two syringes were used, you knew that the third syringe contained the medicine that killed him, and at the same time, you accidentally learned about Watanabe Kiyama's plan, so you changed to a high concentration of potassium chloride, planned this scene with Mr. Hashimon, and then killed him."

Akira Shinhara put the phone back in his trouser pocket, returned the evidence bag to Miwako Sato, and looked at Ishikawa Kakei with a calm look in his eyes.

"What about the evidence?" Ishikawa asked, his lips shaking, as if in a final struggle.

"Why does Mr. Ishikawa still stand and not sit now? Aren't the legs sore? Akira Shinhara's eyes swept over Ishikawa Takei's ankles, meaningful.

"Put a vial with a high concentration of potassium chloride in your trouser leg. You don't dare to sit down because you are afraid that the hem of your trousers will rise and reveal the medicine bottle inside. ”

Wataru Takagi immediately stepped forward and lifted the hem of Ishikawa Takei's trousers, and sure enough, he found a third of the test tube vial there.
