Just as the two said hello and were about to leave, Conan suddenly stopped them.
"Hey, uncle, your button is about to fall off!"
The tall and lanky man looked a little flustered when he heard Conan's reminder, "Oh, no, it's okay."
As he spoke, he reached out and wiped the button.
This scene also attracted Conan's attention, and the eyes of Shirakawa Yuki on the side also flickered slightly.
At this moment, several people ran past.
The leader asked: "Where was the body found?"
The person behind him hurriedly replied: "In the Hanazuki Street train that arrived five minutes ago, the person who died seemed to be a doctor."
Sato and the other two people on the side heard that the person who died was a doctor. They guessed whether it was someone from their medical team and prepared to follow him to take a look.
When Mouri Kogoro heard that there was a body, he got up and went over to take a look. After all, he was the "famous detective" Moori Kogoro!
When they arrived at the scene, everyone saw the corpse's fingers had been broken, the wallet had fallen to the ground, and the body was leaning against the window.
Seeing this scene, Sato was the first to exclaim, "Ah, it's the Utsumi!"
The tall and thin man on the side showed a fierce look, but quickly retracted it, but this scene was seen by Conan and Shirakawa Yuki on the side.
Shirakawa Yuki didn't remember the case this time, but he was basically certain that the murderer was the tall and thin man. After all, whoever showed such a look first in the Conan case was most likely to be the murderer.
She was not prepared to intervene in the case, so she should leave it to the sleeping Kogoro.
Seeing that Sato knew the deceased, Mouri Kogoro on the side quickly asked: "So he is from the same doctors' union!"
Sato confirmed what he said. According to him, the deceased was a doctor named Utsumi, and they were still together last night.
…
"Ah, I have heard of the famous detective Mouri Kogoro for a long time. I am very happy to meet you. My name is Kobayashi Yosuke, and I am the director of the Railway Police Team!"
The man who just took the lead here was very happy after hearing the name of Mouri Kogoro, and quickly introduced himself.
When Mouri Kogoro heard these words, he showed his trademark laugh again, "It's nothing, please give me some advice, hahahahahaha..."
Returning to the scene, Mouri Kogoro asked: "Has the cause of death been found out?"
Kobayashi Yosuke replied: "We are not sure yet. The initial diagnosis is heart failure."
Mouri Kogoro put his hands in his pockets, "Oh, that's right, that's not my specialty."
At this time, Conan discovered the blind spot, "Hey, isn't that the trace of injection?"
Although Mouri Kogoro was very angry when he heard Conan talking nonsense at the crime scene again, he still followed Conan's reminder and looked over.
Sure enough, traces of injection were found in the veins of the deceased.
Seeing that Kobayashi Yosuke confirmed that there was indeed a pinhole at close range, Conan continued: "As long as high-concentration potassium chloride is injected intravenously, symptoms will be exactly the same as heart failure and death will occur."
Seeing everyone become surprised as Conan explained, Shirakawa Yuki couldn't help but put his hand on his forehead. This Conan is really always on the verge of committing suicide.
She didn't want Conan to be exposed so soon, so she explained: "In the human body, there is a potential difference between the inside and outside of the cell membrane, and this potential difference has a very important relationship with potassium ions.
In the human body, especially nerve cells, there is a positive and negative electrical difference between the inside and outside of potassium and sodium ion membranes, and electrical signals are given to control other organs to respond accordingly.
If the concentration of potassium ions in the human body is too high, it will cause nerve cells to send signals that drive muscles to relax, and the heart will slow down or stop beating, which is heart failure.
usually,. Intravenous injection of potassium chloride is strictly prohibited in medicine and can only be administered by slow intravenous infusion or pumping. "
Sure enough, after hearing Shirakawa Yuki's explanation, everyone was attracted and stopped paying attention to Conan's questions.
Dr. Sato on the side looked surprised when he heard Shirakawa Yuki's explanation, "Is this lady a medical student? You know it very well!"
Shirakawa Yuki shook his head, "I just learned some medical knowledge on my own."
Seeing that everyone's attention was on Shirakawa Yuki, Conan secretly breathed a sigh of relief. He had only paid attention to the case just now and forgot that this was not something a child should know.
Because Shirakawa Yuki had shown medical knowledge at Sayuri Matsumoto's wedding before, she did not arouse the suspicion of Xiaolan and the others.
However, because the most critical syringe could not be found at the scene, the case still made no progress.
Conan suggested that this was a homicide case, but was given a hard lesson by Kogoro Mori and then driven outside.
Mouri Kogoro said: "As far as I'm concerned, this is just a case of robbery and murder. You can see that his wallet has been emptied."
Kobayashi Yosuke was a little strange, looking at the fingers of the deceased, "But is it necessary to break all his fingers?"
Mouri Kogoro explained: "What's the matter? The murderer must be too big and he directly suppressed the deceased with force, making him unable to resist."
Conan rolled his eyes while listening outside the window, then walked aside and looked at the train route map and began to think.
Occasionally, he also overheard the conversation between a police officer and the clerk, and learned that the deceased had bought drinks at about 10:50.
But since she couldn't find any thousand dollar bills, she gave the deceased a lot of coins.
At the same time, Conan also learned that a man wearing a dark blue coat, sunglasses and a beard appeared next door to the deceased not long after.
Because of previous police inquiries, Conan also knew which tall and thin man was a doctor named Ida.
At this moment, he suddenly discovered that Dr. Ida's coat was double-sided, and the inside was dark blue.
Recalling the action of wiping the button before and the button that was about to fall off, he had basically determined that the prisoner was Dr. Ida.
But he still doesn't know the method used by the murderer. How did he kill the people on another train?
Returning to Mouri Kogoro, "Uncle, do you really think this is a robbery and murder case?"
Xiaolan felt a little strange when she heard his question, "What's wrong, Conan?"
Conan explained: "Didn't you notice that the witness obviously looked richer? Why didn't the murderer rob her, but chose a victim who didn't look very rich?"
Xiaolan and Mouri Kogoro looked at the witness. It was indeed as Conan said, he looked like a rich man.
Immediately afterwards, Conan looked at Dr. Sato again, "Why does Dr. Sato keep wiping off his sweat?"
Mouri Kogoro looked and saw that this was indeed the case. He felt that Sato might know something, so he walked over.
Conan followed and tugged on Shirakawa Yuki's clothes, "Sister Haruna, do you have any opinion on this case?"
Shirakawa Yuki shook her head, "No, I don't know the identity of the murderer yet."
"Okay." Conan nodded with some disappointment, and then followed Mouri Kogoro.
Shirakawa Yuki looked at the somewhat disappointed cub, chuckled, shook his head, and then followed with his two cubs.
