After gently lowering the shotgun in his hand, Yuichi once again carefully observed the scene of Chihiro Itami's death. In addition to observing the cause of her death, it is also important to find some evidence left by the killer from her.

Especially after the suspected oral saliva of her was found on the shotgun, Yuichi boldly speculated that the murderer had put a gun in her mouth for a period of time, so the murderer did not shoot her as soon as they met, but confronted her for a long time before making a move.

If that's the case, how could Chihiro Itami, who probably knew the murderer, not leave a clue for such a long time, and aside from the suspicious S-shaped mark, maybe there are other hints.

Sure enough, after looking Chihiro Itami up and down, Yuichi finally noticed the weirdness of her corpse's appearance.

"The murderer has put a gun in her mouth, if it is an ordinary person, isn't it subconsciously reaching out to take out this kind of thing that can kill you from your mouth? No matter how bad it is, it will reach out and interfere, right? But why was her hand tightly in her jacket pocket, was there something hidden in it that she was afraid the murderer would find? ”

Thinking of this, Yuichi reached out and followed Chihiro Itami's hand into her pocket, and then a somewhat small mobile phone appeared in his hand.

"Mobile phone? Could it be that she called someone before she died? ”

Skillfully clicking on the phone, Yuichi pressed the redial button and saw a strange set of numbers on Chihiro Itami's phone.

“KIX？ And then there are eight pound keys in the phone bar? Is this a phone call? No one's phone number is going to be eight pound keys, right? If you look at it this way, this is the secret message left by Chihiro Itami? So who does this KIX refer to? ”

Just as Youyi was pondering the phone in his hand, a mournful cry suddenly came from behind him.

"How so? Why does Chihiro ...... Why is this happening? ”

"Yes! How did a big living person who was fine before become like this in a blink of an eye? Mr. Yuichi, can you tell who did it? ”

Turning around and glancing at Komatsu Raiko and Izumi Sano who had already crowded to the door and looked at Chihiro Itami's corpse and wept silently, Yuichi put his mobile phone into the evidence bag, picked up the shotgun on the ground again, and said slowly.

"I've just arrived at the scene, so I can't give you the name of the murderer you want! But if you can cooperate with me and tell me who owns this gun, maybe I'll be able to answer your questions in a moment! ”

"This shotgun? This...... Isn't this the shotgun I use to practice target shooting? It should be kept in an automated locker with an electronic lock along with someone else's gun...... How could it be here? ”

Hearing Yuichi's question, Komatsu Yoriko and the others also stopped crying, and looked at the shotgun in his hand according to Yuichi's prompt, and then Izumi Sano, who was standing behind Komatsu Yoriko, covered his mouth and pointed at the shotgun in Yuichi's hand and screamed loudly.

"Oh? The owner of this shotgun is Miss Sano? And what about that automatic locker? Who locks the electronic lock? It can't be Miss Sano, right? ”

"Nope! Of course not! I am the one who locks the locker, but the password of the electronic lock on the locker is known to everyone in our association, because everyone used to come here often, so for convenience! The password of the electronic lock is set to be the homonym 9017 of the flying target shooting companion, Mr. Yuichi can't doubt me based on this! ”

Hearing Yuichi's inquiry, Komatsu Yoriko on the side immediately responded, but Komatsu Yoriko, who was afraid that Yuichi suspected her, immediately gave a new clue, after all, Judy had already told them Yuichi's identity when she found them before, and for the police who had not been in contact with much, Komatsu Yoriko instinctively distrusted, after all, some policemen often handle confused cases in order to close the case.

Yuichi, who understood Komatsu Yoriko's mood a little, immediately gave her a gentle smile, and after calming the somewhat nervous Komatsu Yoriko, he continued to ask them.

Koji Mizawa, who felt that Yuichi had taken these companions of the Flying Target Shooting Association as murderers, suddenly felt a little uncomfortable when he looked at Yuichi, who had been chasing and beating them fiercely.

"Officer Yuichi! It's true that Sano's shotgun at the scene is our most suspicious, but you can't just look for the murderer among us, right? What if Komatsu didn't lock the electronic lock at that time? In this way, it is possible for others to take out their guns and commit crimes! ”

"Impossible! Kangji! What the hell are you talking about? Have you forgotten that we are obliged to make it impossible for a box with a shotgun to tell what is inside? Koizumi's box is an ordinary suitcase, and the guns are all disassembled and stored, so ordinary people can't easily assemble them. So...... I don't think Officer Yuichi has a problem asking a few of you all the time! ”

"Oh? Mr. Oda, are you here too? ”

Looking at Oda Kunitomo who refuted his companion's remarks for himself, Yuichi greeted him very politely, and then asked Oda Kunitomo about it.

"Since Mr. Oda understands this, then I won't go around in circles, where have you been during the time of the crime?"

"Me? I've been smoking alone in a chair next to the rink since I left you! I didn't go to see the fireworks or go to the crowd because I wasn't really interested in these things! If you have enough manpower, Mr. Yuichi, you might be able to find me some witnesses in the rink! Otherwise, I wouldn't be able to provide an alibi! ”

"Oda! What are you talking nonsense? I can't believe that Chihiro could have been killed by someone in us! There must be some misunderstanding here! Officer Youyi, please don't make judgments lightly! ”

Seeing Oda Kuniyu calmly inquiring with Yuichi, Koji Misawa, who finally came back to his senses from the terrible speculation that Oda Kuniyu said, still roared in disbelief, but after Oda Kuniyu just said that, Komatsu Yoriko and Izumi Sano who were standing at the door both looked a little unsightly, obviously compared to Misawa Koji's unbelief, the two of them had already acquiesced to Oda Kuniyu's speculation. The murderer is likely to be one of the four of them, and the reason is up to the wise. After all, Chihiro Itami's mouth has offended many people.

Seeing that Oda Kunitomo began to cooperate, Izumi Sano, who was standing at the door, followed Oda Kunitomo's words and defended himself.

"Officer Yuichi, can you roughly deduce the time of Chihiro's death? After all, it was too long between the time she left us and the time she found her body. Let's provide an alibi, I'm afraid it's hard! If you can confirm an approximate time, let's also think about whether we can provide an alibi! ”

"Hmmm! What Ms. Sano said is not unreasonable! Then I'll tell you about the time of Chihiro's death! ”

After glancing at the four members of the Shooting Association who had already arrived, Yuichi, who didn't know what he was thinking, agreed with Izumi Sano without hesitation.
