The next day, Mo Xiaoqing got up early and started waiting at the gate of No. 2 Middle School at 8:30.

She deliberately did not wear a police uniform today, but a black down jacket. She always felt that when investigating clues privately, wearing plain clothes would be easier to get closer to.

"Good morning, Officer Mo." Mo Xiaoqing was patted on the shoulder, and a hearty male voice sounded.

Mo Xiaoqing looked back and saw a sunny and handsome young man smiling at her, revealing a row of white teeth.

"Officer Liu, it's you." Mo Xiaoqing was confused. Didn't Captain Xu agree to wait here?

"Why call me Officer Liu? That's too formal. Just call me Xiaobo.

Let's go in together."

Mo Xiaoqing was still looking behind her. Liu Xiaobo turned and said, "Oh, by the way, Captain Xu has other arrangements today, so they called me over to go with you.

Mo Xiaoqing, you won't be unhappy, will you?"

Mo Xiaoqing waved her hands repeatedly, denied it vigorously, and followed Liu Xiaobo into the school.

The high school was on vacation and seemed much quieter. Some students still had to make up lessons at school. A basketball game was going on in the open-air basketball court. Outside the railings, there were girls with red faces, shouting and cheering desperately.

It is understood that the head teacher of the twins, Chen Xiaoshi, taught chemistry. His class was rated as "Excellent Class" every year, and he was also rated as "Provincial Excellent Teacher" and "Excellent Head Teacher" several times.

When they arrived at the classroom door, they found that Teacher Chen needed to give extra lessons to the students, so they were arranged to go to the teacher's office and sit in front of the desk of the head teacher Chen Xiaoshi.

Teacher Chen's desk was very tidy. In addition to some textbooks and students' homework books, there were also some beautifully packaged gift boxes.

Looking at the packaging, it should be candies, chocolates, etc.

Mo Xiaoqing couldn't help but sigh. This head teacher is still very popular with the students in his class.

Liu Xiaobo opened a pink wrapping paper, took out a chocolate from it, raised his eyebrows and said, "Yes, it is especially popular with female students."

Liu Xiaobo handed over a fresh envelope with beautiful handwriting from a girl.

"To Teacher Chen Xiaoshi." What's more interesting is that the teacher also drew a big red heart behind it.

Mo Xiaoqing couldn't help but smile in her heart. Girls nowadays are really getting bolder and bolder. They are so blatant in pursuing their teachers.

"Sorry to have kept you waiting for so long. The class was over but I was stopped by students and asked to answer their questions." A middle-aged man came over with a textbook under his arm.

He was tall, a little thin, with puffy eyes and pale skin. He looked about 35 years old, and seemed to be knowledgeable and well-mannered.

"How about the two police officers go to the meeting room inside to talk?"

There were four or five other teachers working in the teacher's office. Mo Xiaoqing thought it made sense, so she stood up and followed Teacher Chen.

When she was throwing away the garbage in her hand, she looked down and saw some scraps of paper next to the trash basket on Teacher Chen's desk. She couldn't help but get excited and threw those scraps of paper into the basket one by one.

Looking closely, these scraps of paper were all torn pieces of letter paper. After a quick glance, she saw a piece of blue letter paper with the word "Fang" written on it.

Mo Xiaoqing couldn't help but think: How many love letters from girls has this head teacher received? But it's not surprising, high school girls are just beginning to fall in love.

After entering the office and sitting down, Mo Xiaoqing got straight to the point.

"Teacher Chen, I think you should know why we came to see you today!"

"I know, it should be for the twin students in our class." Teacher Chen said with a trace of sadness on his face.

"Oh, what a good pair of girls! The two sisters have excellent academic performance and are usually obedient and sensible. One is the study committee member and the other is the entertainment committee member. They both do their jobs conscientiously.

I had high hopes for them to be admitted to key universities, but I never thought it would be like this. What a pity.

Officer, you can ask whatever you want. I will tell you everything I know."

Mo Xiaoqing said directly, "Well, I remember that at 5:40 pm on January 11, the two sisters Xiang Xinyi and Xiang Xinfang came out of the school gate. From the surveillance video, I saw them I received a phone call, and Teacher Chen, you just happened to pass by them at that time.

Can you recall if you heard what they said on the phone when you passed by?"

Teacher Chen wiped her face with both hands and said, "I really feel guilty now. I was in a hurry to go home to mark homework for my students. When I saw them greet me, I just stayed for a while and then walked away.

What did they say at that time?"

Teacher Chen paused, "Oh, I remember now. I stopped for too short a time and heard some words like "come to pick me up". "

Liu Xiaobo interrupted and asked, "Teacher Chen, are you sure you heard it correctly?"

"I shouldn't have? But I was in a hurry and didn't pay much attention.

Now I think about it, I really regret it. If I had sent them home at that time, it would have been so good. Alas, it's too late to regret it!"

Mo Xiaoqing interrupted, "Teacher Chen, do you live in the same direction as them?"

"Yes, I went to their house for a family visit recently. It's only two stops away from my house."

Mo Xiaoqing then followed the procedure and asked Teacher Chen about the performance of the twins in school and whether they had any abnormal behavior before they disappeared or whether strangers came to the school to look for them?

Teacher Chen answered one by one: The twins are usually well-behaved and obedient, and they are also simple in making friends at school. However, because they both look outstanding, they receive love letters from boys in all classes.

Suddenly, Teacher Chen's eyes lit up, "I remember, there is a student who left a deep impression on me. I have seen him peeking in from the door of my classroom many times, and once I saw him and Xiang Xinyi arguing on the edge of the school playground. But Xiang Xinyi slapped him, and I wanted to stop them, but the boy walked away angrily."

This piece of information given by Teacher Chen was very useful, and Liu Xiaobo asked excitedly, "Does Teacher Chen know this boy?"

"I don't know him. There are many students in the school, but he has been on the same floor as our class, so he should be the same age. It shouldn't be difficult to find him

. Just go to the school's student registration department to check the student information, and then check the surveillance cameras installed in the school corridors, and you should be able to find him."

After hearing what Teacher Chen said, there was no time to lose. Mo Xiaoqing suggested checking immediately, but Teacher Chen said that the school was on winter vacation and many staff members were on vacation.

Teacher Chen called the staff of the student registration department, but unfortunately the person in charge went back to his hometown and would be back in two days.

It seems that we can't confirm the identity of the boy who is entangled with the twin sisters today, but confirming the identity is only a matter of time, which is also a major breakthrough today.

After talking for half an hour, Mo Xiaoqing and the others stood up and prepared to leave.

"Teacher Chen, thank you for your cooperation today. We will send other police officers to investigate the identity of the male student later. Please cooperate with us."

Teacher Chen also stood up and nodded with a smile, "Of course, I also hope that the police can solve the case as soon as possible and give my students justice.

Recently, several parents of students have said that they want to transfer their children to other schools. It is rumored that there is a perverted killer hiding in this school.

Police comrades, please make sure to catch the murderer as soon as possible."

When Mo Xiaoqing was about to leave the office, she suddenly turned back, "By the way, Teacher Chen, I have another question for you. What were you doing from 10 pm to 1 am on January 11? Did you have time to see witnesses?

Please don't mind, Teacher Chen. This is also our routine. We will question all eyewitnesses about this sentence."

"It's okay, it's okay, I understand that. That night..." Teacher Chen thought for a while and said,

"I was marking homework, probably until two or three in the evening. When I came home from school, Grandma Chen in the yard was still awake, and I greeted her at the time. Grandma Chen lives next door to me, she doesn't sleep much, so she should be more aware of my movements."

Teacher Chen answered calmly.

After leaving school, Mo Xiaoqing reported today's progress to Team Xu, and decided to go to the home of Yang Xue, the student who pointed fingers at the twins...
