"Brother Youyi! The location! I understand! Just like Officer Takagi just said, the S-shaped mark next to Chihiro Itami was not written by herself, but was written by the murderer with her blood behind the murderer, which was used to match the shotgun to point the spearhead at Izumi Sano, who was linked to the S in his name. However, as she crouched here to forge the death message, she didn't notice that Chihiro Itami's blood had already flowed onto the ice blades under her feet. ”

"That's right! The four of them, who were Chihiro Itami's companions just now, were all stopped by me, which means that none of them could touch this bloodstain and leave this ice blade blood mark! And if we find blood stains belonging to Chihiro Itami on the skate blades of any of them, then this person is undoubtedly the murderer of Chihiro Itami! If I'm not mistaken, when one of them left just now, there was something interesting left behind where she was standing! ”

After calling a few personnel from the forensic department on the side to check whether the blood stains of the ice blade marks that were marked out belonged to Itami Chihiro, Yuichi squatted and moved a few steps to the door of the toilet, and pointed out two more subtle blood marks to Conan, and Conan, who saw this blood mark, recalled the position of the four people at the scene just now with his perverted memory, although it had been determined that the person was the murderer according to the information left by the mobile phone, but when the real evidence also pointed to her, Conan couldn't help but be shocked.

"It's really her! It is indeed a good means to think backwards, leave things that are not good for yourself, and then create a clumsy way to clear your suspicions! But there is evidence that she killed, so what about the time when she killed? When Xiaolan and I watched the first fireworks, Izumi Sano did rush to our side, if the murderer was her, then how did she perform this trick in front of Sonoko and Yuuichi? ”

Just after Conan determined that the murderer was Izumi Sano, a new question appeared in his mind, because when Izumi Sano arrived, it was not only Xiaolan who could testify to her, but Conan was also present at the time. Izumi Sano's modus operandi is there, but she really can't squeeze out the time to commit the crime.

Conan, who couldn't figure out what the problem was, couldn't help but get up and wander around the bathroom hallway, and just as he was wandering around and didn't know what to do, the two policemen who were sent out to find the bloody clothes by Yuichi hurriedly ran in.

"Report to the Kudo Police Department! We found the bloodstained raincoat and mask you were looking for in the roadside trash can from the bathroom to the rink. And I found this thing in the pocket of my raincoat! Maybe it was left by the murderer, not necessarily! ”

"Oh? Is it? Check the blood stains on your raincoat to see if it's Chihiro Itami, and give me this thing you found! Let me see! ”

"Huh? Is this a five-dollar coin? Since it was left in the raincoat, then it must have a reason for its appearance here, so what is this five-yen coin used for? ”

Just as Youichi was pinching the five-yen coin and thinking, Conan, who returned to the toilet from the bathroom aisle, saw the five-yuan coin, but his eyes lit up, and then he ran to Youichi with excitement and snatched the coin from Yuichi's hand.

While grabbing his mouth, he still seemed to be childish and explained.

"Huh? It's actually a five-dollar coin! Don't you know how to play this? How about I teach you? I just saw Mrs. Yuan a few days ago, and they played like this! ”

Entering a state of reasoning, Conan, who didn't care where the coin was picked up from, gave Yuichi a cute smile, and then put his mouth on the round hole in the middle of the five-round coin and took a deep breath and blew it.

"Whoa—"

"This voice!"

Hearing this familiar voice, Yuyi glanced at the shotgun that had been put away by the forensic department personnel, and finally understood what he and the garden had heard at that time

"Whew!" sound

It was not the first fireworks that rose into the sky, but the sound of the murderer in the toilet using this five-yuan coin and the sound of the shotgun pulling the trigger, and then the fireworks that he and others saw by the window were actually not the second but the first, so that the murderer who left quickly from the bathroom had time to rush back to Xiaolan and them to see the first fireworks.

In that case, the evidence is conclusive! can finally have a showdown with the murderer who has been acting for a long time.

Just as the criminal police officers under Yu and the others set off towards the locker room, in the locker room on the other side, Izumi Sano, who had changed their shoes, also discussed the cause of Chihiro Itami's death.

"Hey! Komatsu! The police officer named Yuichi Kudo just said that the murderer was among the four of us, right? But at the time of the crime, the three of us were obviously watching fireworks in the skating rink! His companions can all testify to us, what does he want to say with such a sufficient alibi? ”

"What else could it be? Of course, it is implied that someone who does not have an alibi is the murderer! Fortunately, I suddenly got excited to watch fireworks today, otherwise I don't like to watch fireworks as usual, and I guess I wouldn't be able to get rid of the suspicion of killing Chihiro, right? After all, my relationship with her in the association is the most tense, and I have to say that the person who arranged the scene is really amazing! You can even think of blaming me! ”

Before Komatsu, who was a little lost, could say anything, Izumi Sano, who had replaced his skates on his feet on the other side, chatted in a weird way.

Hearing her say this, Koji Mizawa's face immediately changed, and Komatsu, who was reacting on the side, glanced at Oda Kuniyu on the side and spoke to persuade him.

"Sano! Don't say that! I believe in Oda's character, he is not such a person! ”

"Huh? Character? Never mind! Anyway, I'm going to return my skates! Kangji! For the sake of so many years of association, I kindly remind you that some people are not as simple as you seem! ”

"Well said! Ms. Izumi Sano's words are really empirical! By the way, you don't have to return that skate for the time being, after all, it's important evidence! ”

"Officer Yuichi! What do you mean? ”

Izumi Sano, who heard Yuichi suddenly interject, turned his gaze to Yuichi Kudo, who was already standing at the door, and after listening to Yuichi's speculation about the death message on his mobile phone just now, she couldn't help but ask nervously.

The smile on the corner of Yuichi's mouth, who saw her like this, became even more open, and after reaching out and pointing to the skates in Izumi Sano's hand, he explained with a smile on his face.

"I won't talk to Miss Sanno about the death message left on that phone, anyway, you won't admit that the above is you! But maybe Miss Sano didn't pay attention to it herself, and when you squatted on the toilet floor and wrote the S-shaped blood stain that pointed to you in Chihiro Itami's blood, the blood that flowed from her body happened to stain the skate blades of the skates on the soles of your feet, so at the crime scene, we found an ice blade mark made of blood marks, so I don't need to continue to explain the rest of the matter, right? ”

All the members of the Flying Clay Shooting Association who heard Yuichi's words couldn't help but look at Izumi Sano, who was not far from them, in amazement.
