"What!?"
After hearing what Karasawa said, Ayanokouji Fumimaro quickly logged into the website of the Juvenile Division of the Kyoto Police Department and found this information with the help of Karasawa.
"Only the murderer and us detectives know that there's Ima Murakami's hair on the button." The middle-aged detective who hadn't left yet said solemnly, "This guy might be the murderer!"
"Let's go to the online class and ask them to lock the IP of this computer as soon as possible and determine its exact location." Ayanokouji Fumimaro immediately stood up and walked towards the online class.
The online textbook is responsible for network aspects, and since it is its own website, it didn’t take long to easily lock the location of this account.
Kyoto International University.
This is the university where the second deceased, Yuta Matsuoka, studied.
After noting down the locked IP address, Ayanokouji Fumimaro drove Karasawa to school.
After stating their identities and purpose, with the cooperation of the school's network personnel, they determined that the IP address of the account that posted the message was in the school's computer room.
The computer room here can only be used by students of this school, and everyone needs to swipe a card at the entrance to enter.
After Tang Ze and the other man asked for the list of students entering and leaving the computer room this morning, they compared the names and found Yuta Matsuoka's name.
"It seems that the account was sent by the criminal."
Ayanokouji Fumimaro saw this and said, "The murderer must have killed Matsuoka Yuta, taken his ID card, entered the public computer room, and left us a message."
As he spoke, Ayanokouji Fumimaro walked to the corridor at the entrance of the computer room and looked around. He then frowned and said, "There's no surveillance at the entrance. We can't even do a comparison and investigation."
"It's probably because of this environment that the criminal used the deceased's student ID to leave us a message."
Tang Ze said without surprise: "This criminal has been very calm since the first case. It is impossible for him to leave such an obvious flaw."
"That's true, but it's still a bit of a pity..." Ayanokouji Fumimaro walked while checking the corridor farther away to see if there were any cameras.
But unfortunately, there is indeed one further away, but in addition to the camera, there are also other entrances and exits.
Looking at the students coming and going up and down the stairs, Ayanokouji Fumimaro could only sigh and give up on following this path.
After all, this is almost like looking for a needle in a haystack.
