Conan glanced at the bloodstains that Kamikawa was pointing at, he had been thinking about the problem just now, and he hadn't carefully examined his surroundings.

There was a lot of blood in the bathroom, and a piece of blood was accidentally stepped on on the ground near the feet of the deceased. Look at the shape of the mark caused by the skate blade of the skate.

Kamikawa Instant and Sonoko didn't enter it before the police came, so it would only be the murderer who caused the mark. And the gun belongs to these people, and the way to open it is only known to these people, and it is only necessary to check the blades of the skates of several people, so it is self-evident who the murderer is.

It's just that......

Conan's eyes looked at the few people outside, why did the murderer do this?

Seeing that Conan understood, Kamikawa instantly stood at the door of the compartment with his hands in his pockets and watched, bowing his head slightly, and the lenses reflected the white light.

Although the evidence is there, there are still some doubts that cannot be explained, Conan held his chin and pondered, "But if that's the case, then how can the timing of their appearance be explained?" ”

"The garden said that she heard the sound of 'boom-' rising into the air at the door, and then exploding, thinking that the fireworks had started, and hurriedly ran to the window, but she didn't know whether it was a problem with the direction or the angle, and she didn't see the fireworks exploding in the air."

Kamikawa reached out and lifted his slippery glasses, and continued, "I think when she heard the sound, it wasn't the sound of fireworks, but the sound of gunshots. ”

"It makes a sound that makes it easy to carry and access......

"Copper coins!" Needless to say, Conan already understood what he was trying to say.

The uncle of the forensic department next to him looked at these two people and asked and answered, and was a little skeptical about life. How do you feel that these two people already know who the murderer is.

It's okay to be older, but isn't this kid too demonic?

I didn't realize this before, but when I reacted, I realized that this little kid was not only not afraid, but even reasoning, which was a bit weird.

"Kid, aren't you afraid?"

"Huh?" Only then did Conan realize that there was a superfluous person here, and he was careless.

He immediately scratched his head and pretended to be a child, and said, "Because I often follow Mr. Maori to investigate cases, I am used to it!" ”

"Mr. Maori...... "If it's the famous detective, it wouldn't be surprising.

"Uncle, could you please go and check their shoes?" Seeing that this person's suspicions were dispelled, Conan took advantage of the situation to trouble others to work.

"Okay." Listening to their discussion here, he naturally understood what they meant. Just check their shoes, and then it becomes clear who the murderer is.

"Tsk, you need to pay attention next time." Watching the other party walk out of the cubicle, Kamikawa looked at Conan playfully, if it weren't for the protagonist's aura, plus the people in the Metropolitan Police Department were not very careful, with Conan's strange appearance, I don't know how many times it would be exposed.

"It's not you yet!" Conan was a little upset with half-moon eyes. In the past, he reasoned in his heart, this guy was talking to him here, and he couldn't help but say the reasoning.

"It's obvious that you got carried away as soon as you investigated the case yourself, what does it matter to me." He doesn't pay attention to his surroundings and wants him to take the blame, no way!

The veteran policeman of the forensic department whispered to Yokozo again, and after getting the other party's consent, he inspected the skates on the spot.

Hearing that they were going to check their shoes, several people looked surprised and looked at each other. Only one of them seemed to realize something, his face turned white and his body stiffened.

"Sano-san, why do you have blood on your skate blades?" Listening to the questioning of the forensic staff, Izumi Sano only felt like he was falling into an ice cellar.

I planned so much, but in the end I failed in such a small detail!

"I ......" she opened her mouth palely, but finally she could only tilt her head away and clench her fists tightly.

"Sano?"

"This...?"

A few of his companions around him didn't react yet, but Oda among them realized something, he gritted his teeth, his cold face turned pale, and his lips trembled a little.

"I think the reason why Miss Sano got blood on her shoes was because she stepped on it when she killed Miss Itami and left in a hurry."

Kamikawa's sudden voice attracted the attention of everyone present, and under the eyes of everyone, he continued unhurriedly: "As long as the police test the bloodstains, it is easy to know where the bloodstains come from. ”

"I think Miss Sano also knows this, so I can't explain it."

Seeing that Shangchuan instantly began to reason, Yuan Zi and Xiaolan walked over, "But... Didn't Miss Sano rush back when the first fireworks started? ”

The bathroom was some distance from where they were, and it took half a minute to get there, at least a minute to process things like laundry, and a few seconds from the time the fireworks rose into the air to when they exploded.

"Yuanzi, that's what you heard at the time!" Kamikawa looked at Conan instantly, and Conan understood that he would take out a copper coin and put it to his mouth.

The sound of 'huh-' came out, like the sound of fireworks rising into the sky.

"That's right! That's right! Yuan Zi nodded, "I wondered why I couldn't see the exploded fireworks, and I thought it was the fireworks behind the window, but I didn't expect it to be the sound of fireworks." ”

Yuanzi's mind was also working at this moment, "If you say that, the sound of the explosion is very similar to the sound of gunfire." ”

"That's right. This is how Miss Sano uses this technique to hide the sound of the shot, so as to confuse the time for the purpose of alibi. ”

With such a good brain, it's a pity that this girl is not a killer.

"Sano... Why? Komatsu Yoriko couldn't cry.

"Because of Narita! Narita committed suicide because of her, and I did this just to avenge him. It was pointed out that she calmed down. After all, the result has been decided, and what he says later will not affect his ending, it is better to say it quickly and reveal the past things buried in his heart.

"However, Narita's suicide was a complete accident!" Yasuo Misawa didn't understand why things had come to this point. Of the six friends who shot together, one of them died last year, and Chihiro died today, but it was Sanno who killed her.

It was all good at first, and everyone had a lot of fun together......

Chihiro told Narita that day that she was going to break up with Narita, so Narita pulled the trigger on her gun. Later, when the police checked the guns, the case was decided by accident......"

These things are buried in the bottom of my heart, and every time I think of them, my anger deepens, until the anger begins to burn and things become irreparable.
