"Zhenyu is the most popular young female professor in our school, she is beautiful, and she is still single, so she is very bad and jealous. Therefore, she is often rumored to be bad by some well-intentioned people. ”

In the cake shop outside the Toto Medical University, Takayama Ayase ordered a cake set, sat on a chair in the store, looked at Takato opposite, and explained.

Recently, there have been a lot of people who have come to ask about the details of her murder, but most of them are also news reporters who have come to talk about Zhenyu. However, it is the first time that a detective will come to investigate. ”

Sincerely, Takayama Ayase said as she looked at Takato.

"By the way, Mr. Detective, I haven't asked your name yet."

"Be wise and lofty."

Takato replied.

In this regard, Takayama Ayase nodded, pondered, and after confirming that he had not heard of the name, he continued with some suspicion:

"It's been almost a week since Zhenyu was killed, and the police haven't investigated yet. Are you sure you can solve this case, Mr. Wise? ”

It seems to be a distrust of Takato's identity, Takayama Ayase said.

In this regard, Gao Yuan just smiled helplessly, "Teacher Gao Shan, you can tell me the details of the case that you know, maybe I can find something." As for Professor Sawaguchi's rumors, you can keep your mouth shut, after all, I'm a detective, and all I care about is the case. ”

Hearing Takato say this, although Takayama Ayase did not dispel his suspicions, since he had chosen to meet and talk with the other party here, with the mentality of trying it out, Takayama Ayase told Takato what he knew about the case, and after listening to Takayama Ayase's narration, Takato roughly understood the case:

The cause of death of Professor Mayu Sawaguchi was excessive blood loss caused by a sharp blade inserted into the heart from the back, and the murder weapon was not found at the scene, and the scene of the crime was her own apartment.

According to the time of death, it is speculated that the time of the crime should have been between the evening and the night of last Thursday.

The police investigated the situation at the scene and determined that it was not a theft or robbery, and that the murderer should have been someone who knew the deceased, and after being invited to the deceased's home, he attacked the deceased from behind when the deceased was completely unsuspecting.

"That's it...... These? ”

After listening to Takayama Ayase's narration, Takato was slightly stunned, not quite understanding why such a case could become an unsolved case.

"Judging from the fact that Professor Sawaguchi is a single woman who lives alone, she can be invited into the room at night without guard, and the murderer is obviously a person who has a very good relationship with her, as long as you investigate her interpersonal relationships, you should be able to find the murderer, right?"

"Indeed, the police are investigating in this direction, and they also came to the school to question us at that time."

Takayama Ayase confirmed, "But in the end, no one was found. ”

Hearing this, Takato frowned slightly, feeling that Takayama Ayase seemed to be hiding something, so after thinking for a while, Takato took out his mobile phone and dialed Takagi Watabu's number, asking him about the details of Sawaguchi's death and not being able to find the suspect.

"Huh? Mr. Wise, are you looking into this? ”

On the phone, Takagi Shi heard Gao Yuan's request and couldn't help but say with some surprise.

"I happened to be at Dongdu Medical University, and I heard about this case, so I was a little interested."

Gao Yuan said sincerely.

"That's right!"

Feeling a little surprised, Takagi couldn't help but say: "It just so happens that I am about to go to Dongdu Medical University, and I want to make some more inquiries about this case, why don't I explain it to you in person!" ”

In this regard, Takato naturally readily agreed, so it didn't take long for Takaki Shibu to come to the cake shop, say hello to Takato and sit down next to Takato, and then greeted Takayama Ayase:

"Mr. Takayama, it just so happens that you are also here, I am Takagi of the Metropolitan Police Department, and I want to confirm some things with you."

Takayama Ayase did not refuse, after all, this was not the first time she had seen Officer Takagi, and the fact that Takato was familiar with the criminal police made her let go of her doubts about Takato's identity.

"Officer Takagi, what's the matter with not finding a suspect in this case? The murderer should be someone familiar to the deceased, right? ”

After Gao Yuan sat down with Takagi Wataru, he directly raised his own questions, to which Takagi Wataru also answered very simply:

"Because, based on the inference of the time of death of the deceased, during the time period of the crime, there may be people who may be suspected, and there are sufficient alibis."

"Suspicious people?"

Hearing this word, Takato emphasized it, and Wataru Takagi also replied:

"That's right. We investigated the deceased's interpersonal relationships and found that there were two people who had a motive for committing the crime, one was the first discoverer of the case and the deceased's sister, and the other was the deceased's ex-boyfriend who had lived with the deceased. ”

"Well...... My sister and ex-boyfriend, what is their alibi? ”

Gao Yuan couldn't help asking.

"According to the forensic inference, the time of death of the deceased was around 7 o'clock on Thursday night, and during that time, the deceased's sister was working overtime in the unit until 10 o'clock in the evening, and did not leave halfway, which a company colleague can testify. The deceased's ex-boyfriend attended a class reunion that night and left for about five minutes to go to the toilet halfway, but the place where he met was more than 30 minutes' drive from the scene of the crime, so his alibi was also established. ”

Wataru Takagi replied.

After hearing this, Gao Yuan thought for a moment, and then said lightly:

"The ex-boyfriend can call the deceased to the vicinity of his class reunion at seven o'clock, and then use those five minutes to kill her, hide the body, and wait until the class reunion is over, and then get the body back into the apartment, pretending that the deceased's apartment is the first crime scene."

In this regard, Takagi Wataru said helplessly:

"Mr. Wise, about this idea, our police also thought of it, so we did a special investigation, but it turned out that this was not true at all, there was no trace of the body moving, and the apartment was indeed the first crime scene."

"That's right."

Gao Yuan said--It's really not that easy.

"So, we, the police, are now looking for other suspects on the point of whether the deceased had relationships that we don't know about...... After all, there are so many bad rumors about the dead......"

"Zhenyu is definitely not that kind of person!"

Hearing Wataru Takagi say this, Takayama Ayase on the side immediately retorted angrily, "I have known her for twenty-three years, and she was a student of this school when I first came to work at the school. For those rumors of Zhenyou, I can guarantee that they are all false! ”

"But...... Mr. Takayama, although you are said to be a good friend of the deceased, there are things you don't know after all! ”

Seeing Takayama Ayase's reaction, Wataru Takagi couldn't help but say helplessly.

"When I say impossible, it's impossible!"

Hearing Wataru Takagi say this, Takayama Ayase became even more angry, this female teacher who looked kind and well-behaved, was saying angrily at the moment:

"Since then, Zhenyou has always liked that person in her heart, and it has never changed! How could she do such an inappropriate thing! ”
