"Yes...... But ......"

Faced with Takayama Ayase's excited reaction, Wataru Takagi couldn't help but feel a little overwhelmed, and he didn't know what to say for a while.

"That...... Mr. Takayama. ”

At this time, Gao Yuan suddenly asked out loud, "Who is the 'person' you are talking about?" ”

"That's right!"

Hearing Takato's inquiry, Takaki Wataru suddenly had a flash of inspiration, and also asked, "Mr. Takayama, you have never mentioned to us before that Professor Sawaguchi has such a past. Perhaps, the person who killed Professor Sawaguchi is the 'man' you mentioned! So, can you tell me, who is 'that person'? ”

"It's impossible."

After listening to Wataru Takagi's inquiry, Takayama Ayase shook his head a little vainly, "Because that person, more than ten years ago, was already dead!"

"Hey...... Is that so? ”

Hearing this, Wataru Takagi couldn't help but be a little surprised, "In other words, Professor Sawaguchi, for the sake of a dead person, has he been celibate for so many years?" ”

"Yes."

Takayama Ayase nodded a little sadly:

"When I heard about that person's death from Mayu, I was also shocked, I didn't expect that such a genius pharmacist would die like this. For this reason, I also advised Zhenyu to let go of the past and try to meet a new future. ”

"Then her ex-boyfriend dated after this?"

Hearing this, Wataru Takagi seemed to understand something, so he asked.

And after hearing Takayama Ayase's narration, Takato couldn't help but be a little surprised, lowered his head and pondered - that person?

Takayama Ayase in front of you...... There is also Mayu Sawaguchi, who was a former student of Toto Medical College...... Twenty-three years ago...... Is it possible? No way!

"That's right."

Takayama Ayase said, "When I saw Mayu start dating other people, I thought she had come out. However, when it came time for them to talk about marriage, Zhenyu suddenly repented - because she never forgot that person. ”

"So, that's why Mr. Anda has a conflict with Professor Sawaguchi, right?"

Wataru Takagi asked, and the so-called Mr. Adachi is Shinyu Sawaguchi's ex-boyfriend, whose full name is Kazuo Adachi.

"Yes!"

Speaking of this, Takayama Ayase couldn't help but be a little excited, "Because of this incident, Kazuo Anda has never been able to forgive Mayu, and even stalked and harassed Mayu for a time. Those rumors of Zhenyu are almost all rumors made by Kazuo Anda...... Mr. Officer! The murderer must be Kazuo Adachi, can't be wrong! After all, on the day of the crime, Kazuo Anda also came to school to have a big fight with Zhenyu! ”

In this regard, Wataru Takagi could only wave his hand helplessly:

"Calm down, Mr. Takayama. As we said before, although Mr. Anda did have an argument with Professor Sawaguchi on the day of the crime, after all, he had a perfect alibi, so he ......"

"He must have used some kind of trick!"

Takayama Ayase said unwillingly.

"However, the current situation really does not find any loopholes in Mr. Anda's alibi, so ......"

Takagi Wataru said, looking at Takato who was silent on the side with some embarrassment, before continuing:

"Mr. Wise thinks so too, right?"

"Huh?"

Hearing Takagi wade calling his name, Gao Yuan came back to his senses, responded, and then thought for a moment and asked:

"Officer Takagi, I actually have a question that I haven't figured out. The deceased was only found in the afternoon of the next day, right? A corpse like this found the next day can generally only delineate the time of death within a certain period of time. But why did you say that the time of death of the deceased was around seven o'clock in the evening, which is a very precise time? ”

Wataru Takagi explained:

"Ah, that's what you say. Indeed, if we infer from the changes in the corpse, such as ultrasonic reaction, corpse cold, corpse spots, and corpse mortis, we can indeed only delineate an approximate time of death, and then further infer the degree of digestion of the gastrointestinal contents, and then further narrow the scope. ”

As he spoke, Wataru Takagi took out the police manual, looked through the contents on it, and continued:

"In this case, because we can accurately know what Professor Sawaguchi ate and when he ate on the day of the crime through the restoration of Professor Sawaguchi's trajectory that day, we can more accurately know the estimated time of death."

Hearing this, Gao Yuan seemed to have discovered something, and asked:

"Can you tell me about the deceased's movements and food that day?"

"Okay."

Looking at the police handbook, Wataru Takagi explained:

Professor Sawaguchi came to the school's office at half past eight in the morning on the day of the crime. At about nine o'clock, Mr. Anda also came to the school and had a fight with Professor Sawaguchi in the office, which lasted about ten minutes, and then Mr. Anda left angrily. Then, during the lunch break at 12 o'clock, Professor Sawaguchi ate his own lunch box in his office. After that, it's three o'clock in the afternoon......"

As he spoke, Takagi pointed to the cake shop he was in now, and continued:

"At three o'clock in the afternoon, Professor Sawaguchi was also at this cake shop, ate a cake set, and then went home around half past three. Finally, at around 7 p.m., Professor Sawaguchi made dinner at home, and before he could eat it, he was killed. ”

"The timing is so precise?"

After listening to the timeline combed by Takagi, Takato couldn't help but ask.

"Yes, because before every meal, Zhenyu is used to taking photos of the food she wants to eat and posting them on her 'Twitter' account page."

Takayama Ayase explained.

"That's right, we checked Professor Sawaguchi's Twitter page and found out that this is indeed the case. And the food photos and release time she sent on the day of the crime are consistent with the clues we have. At the same time, it was precisely because Professor Sawaguchi's account did not post the photo on time the next day that Professor Sawaguchi's sister felt strange, and after going to the apartment to check, she found out that Professor Sawaguchi had been killed. ”

Hearing this, Gao Yuan couldn't help but sit upright, clasping his hands on his chest, as if he had thought of something, revealing a sudden look.

In this regard, Takagi Shibu, who saw Gao Yuan's expression, couldn't help but be pleasantly surprised:

"Mr. Wise! What are you...... Do you already know what's going on? ”

"Probably."

Gao Yuan said lightly, and then asked Takagi Wataru a question:

"Officer Takagi, if you only look at the changes in the body, when did the medical examiner infer the time of death of the deceased?"

"This? Let me ask! ”

Faced with this question, Wataru Takagi was obviously unprepared, but he immediately took out his mobile phone and called to ask.

"If you only look at the changes in the body, the time of death of the deceased should be between four o'clock in the evening and eight o'clock in the evening."

Hanging up the phone, Wataru Takagi informed Takato of the result.

In this regard, Gao Yuan couldn't help but smile clearly-

"Officer Takagi, the murderer's alibi, I can see through it!"
