Conan glanced at the blood stains that Xiang Guaikawa was pointing to. He had been thinking about the problem just now and did not carefully check the surroundings.

There was a lot of blood in the bathroom. On the ground near the feet of the deceased, a piece of blood was accidentally stepped on. Look at the marks formed by the ice skates that were shaped like ice skates.

Shun Kamikawa and Yuanzi had never entered before the police came, so the only one who caused this mark would be the murderer. The gun belonged to these people, and only these people knew how to open it. You only need to check the blades of the ice skates of several people. Then it goes without saying who the murderer is.

only……

Conan looked at the people outside, why did the murderer do this?

Seeing Conan understand, Gunkawa stood at the door of the compartment with his hands in his pockets and looked at him, lowering his head slightly, and the lenses reflected a white light.

Although there was evidence, there were some doubts that were not explained. Conan held his chin and pondered, "But if that was the case, how would the time they appeared explain?"

"Sanzi said she heard the sound of "swish" at the door and then exploded. She thought the fireworks had begun and hurried to the window, but she didn't know whether it was a matter of direction or angle, and she didn't see the fireworks exploded in the air."

Hanagawa Shin reached out to support the falling glasses and continued: "I think when she heard the sound, it was not the sound of fireworks, but the sound of gunfire."

"It can make such a sound, and it is easy to carry and use..."

"Copper coins!" Without going to Kawashima, Conan already understood what he wanted to say.

The uncle from the forensic department next to him looked at the two people asking questions and answers, and was a little doubtful about life. Why do you feel that these two people already know who the murderer looks like?

It would be fine if that older person is, but is this kid too evil?

I didn't realize this before, but when I realized that the child was at the crime scene, not only was he not afraid, but he was even reasoning. This was a bit strange.

"Kid, aren't you afraid?"

"Ah?" Conan realized that there was a redundant person here and was careless.

He immediately scratched his head and pretended to be a child, saying, "Because he often follows Mr. Maori to investigate cases, I'm used to it!"

"Mr. Maori..." If it were that famous detective, it would not be surprising.

"Uncle, please check their shoes, okay?" Seeing that this person was dismissed, Conan took the opportunity to trouble others to work.

"Okay." Listening to their discussion here, he naturally understood what they meant. As long as he checked their shoes, the murderer would be revealed.

"Tsk tsk, you have to pay attention next time." Watching the other party walk out of the compartment, Guekawa Shin looked at Conan jokingly. If it weren't for the protagonist's halo and 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!" Conan felt a little unhappy with his half-moon eyes. In the past, he thought to himself that this guy was talking to him here, and he couldn't help but tell the reasoning.

"It was obvious that you were so proud that you would be so proud that you would be so important when you investigate the case. What does it have to do with me?" He didn't pay attention to the surrounding environment and asked him to take the blame, and there was no way!

The old policeman from the forensic department whispered to Henggou Shigewu, and after obtaining the other party's consent, he checked the skates on the spot.

When they heard that they wanted to check their shoes, the few people looked surprised and looked at each other. Only one of them seemed to realize something, his face turned pale and his body was stiff.

"Miss Sano, why are there blood stains on your ice skates?" Listening to the question from the forensic department staff, Sano Izumi felt like she was falling into an ice cellar.

After planning so many plans, I ended up losing in such a small detail!

"I..." She opened her mouth pale, but in the end she could only turn her head and clench her fists tightly.

"Sano?"

"this...?"

The few companions around him were still unresponsive, but Oda among them realized something. He gritted his teeth tightly, his cold face turned pale and his lips trembled a little.

"I think the reason why Miss Sano's shoes were covered with blood should be because she stepped on it when she killed Miss Itan and left in a hurry."

Guestawa Shun suddenly made a sound, attracting everyone's eyes. Under the eyes of everyone, he continued calmly: "As long as the police test the blood stained, it is easy to know where the blood stains came from."

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

Seeing Mikawa Shun began to reason, Yuanzi and Xiaolan walked over, "But... Didn't Miss Sano come back when the first fireworks began?"

This bathroom is a distance from where they were at that time, and it will take half a minute to arrive at the fastest time, and it will take at least one minute to deal with clothes and other things. The time from the launch of fireworks to the explosion is only a few seconds.

"Yuanzi, what you heard was this sound at that time!" Mitsukawa looked at Conan, who understood and took out a copper coin and put it next to his mouth.

The sound of ‘swish--’ came out, like the sound of fireworks rising into the sky.

"That's right! That's right!" Yuanzi nodded, "I wondered why I couldn't see the exploded fireworks. I thought it was the fireworks on the back of the window, but I didn't expect it wasn't the sound of fireworks."

Yuanzi's mind was also working at this moment, "If you say so, the sound of explosion is very much the sound of shooting."

"That's right. Miss Sano uses this technique to hide the sound of shooting, thus confusing time to achieve the purpose of absent-present proof."

With such a good brain, it would be a pity for this girl not to be a killer.

"Sano...Why?" Komatsu Raiko burst into tears.

"Because of Narita! Narita committed suicide, I did this just to avenge him." She calmed down after being pointed out. In the end, the result was settled, and nothing he said later would not affect his ending. It would be better to say it out loud and reveal the past that was buried in her heart.

"But, Narita's suicide was a complete accident!" Yasuo Mizawa didn't understand why things had developed to this point. The six friends who shot together, one of whom died last year, and Chihiro died today, was Sano who killed her.

It was obviously all the time at the beginning, and everyone had a lot of fun together...

"That day Chihiro told Narita that she planned to break up with Narita, so Narita pulled the trigger at herself with a gun. Later, when the police checked the gun, the case was decided by accident..."
