Zhao Yu didn't bother to answer Li Beini's question. After hanging up the phone, he rushed into the crowd and quickly looked for Shanshan's mother who was playing the piano.

"Hey? It's you!" Soon, Shanshan's mother was found by Zhao Yu. He hurriedly asked, "Sister! Tell me quickly, did you recognize Gao Tian when you participated in that piano competition? Yuan Lili and Luo Meina?"

Shanshan's mother's expression had long been frozen, and she retreated and shook her head as if she was hiding from the plague god.

"No, after so many years, how can you deny it in one go?" Zhao Yu asked hurriedly, "Think about it carefully, do you know these three people? Did they participate in the piano competition with you?"

"I... I really can't remember!" Shanshan's mother was frightened by Zhao Yu's aggressive aura, and turned around and wanted to avoid it.

Zhao Yu grabbed her arm and shouted, "Sister, sister, why are you afraid of? I'm investigating the case!"

"Hey! Parent, I have tolerated you for a long time!" Finally, the white-haired head teacher could no longer watch, slammed the table, stood up and shouted, "Stop it quickly, or I will call the security guard! Your quality is so devastating!"

"That's it!" The male parents next to them had already started rolling up their sleeves, "You don't even look at where this is, see who you are?"

Zhao Yu was reminded by one sentence. He hurriedly took out the police officer's certificate and shouted: "I am a policeman! The serious crime team is investigating the case! There is a major murder case now that may be related to this lady, so..." He faced Shanshan's mother and said, "You must answer my question truthfully, otherwise, you will go back to the police station with me...hey..."

Unexpectedly, when she heard that she was involved in a major murder case, Shanshan's mother rolled her eyes and fainted! The parents next to her pinched the person and patted her chest again, and it took her a long time to recover.

"Police officer! Where are you investigating the case like this?" The head teacher ran over and complained, "Look... what did you make our parents look like? This is a school!"

"That's it!" The parents next to them all blamed, "I haven't heard of arresting people from the parent-teacher meeting? Looks like I'm scared?"

"Hey, are you really a policeman?" Someone said suspiciously, "You open your mouth and keep silent. How can the police be like you? Teacher Wang!" He said to the head teacher, "I think you should confirm his identity first!"

"Fart!" Before these parents shared the same hatred, Zhao Yu shattered them with a loud shout, "To tell you the truth, the murderer may commit another crime today. If your obstruction hinders me from investigating the case and let the murderer commit the crime again, you will be obstructing official duties and will not be able to take care of me!"

After all, the parents here have never seen any big scenes. They were really frightened by Zhao Yu's words, and they all shut up and dared not say anything.

"Police officer! It's been 20 years!" Shanshan's mother said with a pale face and trembling all over, "How can I remember who should be against whom? I was nervous enough to play on stage, so I still have the heart to care about others? I really have never heard of these three names you said!"

oh……

Zhao Yu thought about it and soon realized that no wonder the three victims had participated in piano competitions together, but they had no impression of each other! First, the age is long, and second, the piano competitions are compared with personal skills, and there is basically no communication between them.

"Wait a minute," Zhao Yu suddenly remembered something again and asked Shanshan's mother, "Which piano competition was you participated in at that time? Do you always know this?"

"I know, I know... well..." Shanshan's mother nodded repeatedly, and then tried hard to recall, "It's either the second or the third, at most the fourth! Anyway, it should have been held for a short time at that time!"

call……

Zhao Yu shook his head repeatedly. Gao Tian and others participated in the 10th Piano Competition. The ages are a bit different, so Shanshan's mother naturally couldn't know them!

Since that's the case, we can only start with the original information of the competition! Zhao Yu believes that as long as the list of people who can find that piano competition, the murderer may surface!

"That... what teacher is here?" Zhao Yu asked the white-haired class teacher in a rough voice, "Tell me, if I wanted to find information about holding a piano competition from here, who should I find?"

"Well... you have to ask the vice principal who specializes in music..." The head teacher frowned, "But after so many years, I don't know if I can find those information!"

"Where is the vice principal's office? How to get there?" Zhao Yu asked as an orderly.

The head teacher did not dare to disobey, so he quickly told him what Zhao Yu wanted to know. Zhao Yu turned around and left the auditorium.

It was not until Zhao Yu completely disappeared that these parents breathed a sigh of relief. After a moment of sank, someone asked again:

"Who is this person...? Is it a student's parent?"

"No, right?" The head teacher was also puzzled, "I have never seen such a person before? What kind of criminal police officer in the serious crime team? Why are they like a hooligan? If the students in our class have such parents, they will be in trouble!"

"I know, I know!" At this time, a female parent raised her hand and replied, "I saw that he came with Jiang Xiaoqing! It should be Jiang Xiaoqing's parents!"

Dong!

The head teacher didn't stand firmly and fell to the ground!

...

After coming out of the auditorium of the music building, Zhao Yu directly found the vice principal. As soon as the police officer's certificate was revealed, the vice principal cooperated very much to find the archivist.

However, when Zhao Yu followed the administrators to rummage boxes and cabinets in the archives room for a whole morning, he did not find any information about the piano competition. Not to mention the participants, they even saw the charter, details, etc.

One of the administrators said that the time has been separated by too long! This kind of competition information is not as important as other files, and the significance of storage is not very great. After several changes in the school, the possibility of survival is very slim!

After receiving such news, Zhao Yu was greatly disappointed. He immediately asked several administrators to say that it was related to human life and asked them to look for it again no matter what.

The administrators naturally knew that it was a big deal and immediately assured Zhao Yu that they would continue to search and see if there was any possibility of missing a corner of the school. Once there was news, they would call him as soon as possible.

That being the case, Zhao Yu had to leave here temporarily and find other solutions. Unexpectedly, as soon as he came out of the gate of No. 2 Middle School, the phone number from Li Beini rang:
Chapter completed!
