Why are there so many suspects this time... Scanning the list, Ye Gengyi quickly calculated the number of people on it:
"Fifty-eight."
Eh?
Here he was counting his fingers, and Mu Mu Shisan, who had just counted to 3, his expression froze, and he was a little confused. For a moment, he didn't know whether to believe it or to pretend not to hear and continue counting...
Seeing this, Ye Gengyi said:
"Standard A4 paper, size 3 font, visual inspection of the top margin is about 3.7 cm, the bottom margin is about 3.4 cm, 1x line spacing, each column has a maximum of 20 lines, and the third column is missing two names, so there are 58 people."
Mu Mu Thirteen: "..."
Ah, this... Teacher Judy taught me English before, and later a brother taught me arithmetic...
(╯‵□′)╯︵┻━┻
What's wrong with not studying hard? Are you eating your rice? !
"Ahem... It's true that there are fifty-eight, but it's really not easy to filter out these people one by one." On the side, Takagi Wataru coughed twice, trying to smooth things over for his police department and change the subject.
"Leave it to Officer Sato to screen the suspect. Takagi, go to the forensic officer and ask if the fingerprints of the deceased have been identified."
Mumu Shisan folded the list and handed it over, and stood up and walked out of the coffee shop as if nothing was wrong.
Officer Sato?
Chiba and Nobu on the side silently took the list.
She was interrogating prisoners at the Metropolitan Police Department, but she didn't come...
The Memu Police Department must be embarrassed right now... The others looked at each other and reached a consensus.
...
Everyone came to the escalator again.
A moment.
Takagi Wataru jogged back and whispered: "The forensic officer has confirmed that the fingerprints of the deceased were indeed found in the blood symbols on the file bag, and I also found an eyewitness, but he was worried about being harmed." The murderer refused to come to seek revenge, so he only provided his testimony.”
"Didn't you see the murderer's face clearly?" Ye Gengyi predicted in advance.
"Uh, yes." Takagi Wataru nodded: "The witness only saw a man in a coat stabbing the deceased in the abdomen..."
As he spoke, he walked to the escalator, pointed at the blood stains on the ground and said:
"It was here that when the murderer and the deceased were fighting each other for the file bag, the power suddenly went out... When the lights came on, witnesses saw the murderer taking out a stack of documents-like things from the file bag and then running away. Went up there.”
Was it before the power outage... Ye Gengyi walked to the escalator, looked down from a high position, and found that except for the area where the deceased's body was, there was no blood anywhere else.
It should be on another rung.
Just as he was thinking about it, a big head suddenly appeared in his sight.
Conan said with a smile on his face: "Brother Gengyi, you really noticed it too, right?"
Launch the escalator and look for hidden clues?
Ye Geng said: "No."
Ah, this... Conan, who was planning to take advantage of his identity as a brother, asked for the file bag from the police and confirmed his suspicion, paused in his smile.
"It seems that we still have to unravel the meaning of the '○╳△' message left by the deceased in blood first." Mumu Shisan's eyes were deep.
To be so free... From the corner of his eye, he caught sight of Ye Gengyi chatting with Conan.
I was about to ask.
On the side, Suzuki Sonoko guessed: "Could the cross represent '×' for multiplication, and the circled triangle refers to a certain mathematical formula?"
"But why is it written as a circle, a cross, and a triangle?" Mao Lilan wondered.
"Because I'm worried that the murderer will discover it," Suzuki Sonoko explained confidently: "If it is not replaced with this symbol, the criminal will probably destroy the evidence if he sees it."
If he had that kind of opportunity, why didn't he snatch the entire portfolio... Judy Stelling secretly complained and quietly returned the topic to Ye Gengyi:
"So, the murderer must be very proficient in mathematics?"
Proficient in math?
For example, the guy who can count 58 people on the list in less than 2 seconds...
Mu Mu Shisan first turned to look at Ye Gengyi. Seeing that the other party had not finished talking, he had to turn to Fan Jiu in the next life and asked:
"Is there any employee in your company who is particularly good at mathematics?"
"No," the next life Fan Jiu shook his head, "Because of our business, our company recruits mainly liberal arts students..."
"That's right!" Mao Lilan had an idea: "Teacher Judy, Yuanzi... Do you think this cross refers to 'x', which is the cute mark that the teacher mentioned in English class... .”
"Eh? Pfft...hahaha..."
Hearing Xiaolan say this, Suzuki Sonoko and Judy Starling looked at each other and suddenly laughed narrowly.
"Impossible, absolutely impossible..."
"No! No! Mori-san, you are definitely overthinking..."
The two waved their hands repeatedly, denying her guess.
However, because the movement was too loud, it attracted Takagi Wataru on the side:
"The 'x' you are talking about is something that girls often write at the end of letters..."
"Eh? Officer Takagi, do you know what 'x' means?" Mao Lilan turned around in surprise.
"Oh? Does this mean you often receive letters like that?" Suzuki Sonoko leaned over, bumped him with her elbow, and teased: "Who sent it to you? Officer Sato or someone else... .”
"No, no," Takagi Sheba said with shame, "It's all someone else's prank..."
"Takagi, what does that 'x' mean?" Megure Thirteen asked.
"It's nothing. The 'x' we just mentioned has nothing to do with this '○╳△' code..."
"Maybe it's not just a 'circle and triangle'..." Before Takagi Wataru could finish speaking, he was interrupted by Conan who couldn't ask for it and grabbed it instead.
Everyone turned their heads and saw a certain detective pointing at the file bag that had just been taken from the police officer and said, "Look at the left side of the circle, which is the edge of the file bag. There is blood on it. Is this right?" It means that apart from these three symbols, what else did the deceased write?"
"You are talking about this," Takagi Wataru explained: "We have noticed it before, but we have searched other places in the elevator and escalator and found no similar traces..."
"Have you checked all the steps of the escalator?"
Conan continued:
"Don't forget, although the escalator is stopped now, it should have been running when the body was found. If the "death message" on the file bag is not complete, then the missing part must be in On this ladder!"
"So that's it!" Takagi Wataru suddenly realized, "I'll go find the forensics personnel right away to confirm!"
"But Conan, thank you for noticing this detail, but it's better than some... Huh?"
Mumu Shisan planned to take the opportunity to hit a certain technical association expert, and was about to get angry, but when he turned around, he found that the target was missing: "Where's Brother Gengyi?"
"Strange, he just..."
Wait, this familiar feeling of déjà vu... Conan's eyes widened. Could it be that Brother Geng had discovered some clues that he didn't know about? !
