Zhang Yichi returned to the bureau and immediately began to retrieve relevant videos and investigate them one by one.

When he asked the head teacher in the morning, he asked the head teacher about his travel record in the morning, and asked him to recall the specific time as much as possible. He now focuses on checking what the head teacher said, and if the video results are different from what the head teacher said, then there is likely to be a ghost.

Just querying these videos is relatively labor-saving.

It took Zhang Yichi an hour to basically finish the check, and after watching the videos one by one according to the travel route said by the head teacher, he did find the head teacher.

After the time comparison of each monitoring point, the time is also tightly matched and there is no omission, which excludes the possibility of the class teacher falsifying travel records.

In this case, the doubts are even greater.

If the head teacher was the murderer, how did he manage to let Zhong Mingya die after only one face-to-face fight? How did Chen Chen jump to his death without going to school in the morning?

Could it be the same as the last reincarnation world?

Zhang Yichi remembered the method of killing his younger brother with multiple personalities in the last reincarnation world, the murderer also had an alibi, and his method of committing the crime was to induce the killing of his younger brother with autism.

Did the murderer in this case also kill Zhong Mingya and Chen Chen through inducement?

Analyzed in this way, the head teacher can indeed commit murder by inducing. Because Chen Chen is his student, it is not difficult to induce Chen Chen, and Chen Chen's personality is relatively introverted, so he may not be induced to commit suicide subtly.

But how did the head teacher induce Zhong Mingya? He and this female star should not know each other, and there is no connection between them at present, and theoretically, the head teacher cannot induce Zhong Mingya.

And what was his motivation for doing so?

The motive is also unclear.

There are still some doubts about this speculation, but it can be used as a reference for ideas. Zhang Yichi wrote down this idea, took a sip of water and emptied his brain.

After a short break, he pulled out the note again.

"Die, hee-hee. 】

Is this a prank by the students or a provocation by a murderer hiding in a dark place?

Zhang Yichi currently has a handwriting sample of the head teacher, so he doesn't need to find any more materials, and he can directly take them for comparison.

If it is the words of the head teacher, it will be excellent news, and it will become strong evidence that the head teacher is the murderer. If not, it will be very puzzling to Zhang Yichi.

Why did Chen Chen's classmates write such a note to Chen Chen after he committed suicide by jumping off a building?

Zhang Yichi couldn't figure it out.

He shook his head slightly, put aside these miscellaneous thoughts, cheered up, and took the note and the sample of the head teacher's handwriting to compare.

Mo Ji drove to Chen Chen's house.

At present, Chen Chen's body has not been transported back, and an autopsy is still being conducted.

Many relatives and friends are now at home to comfort Chen Chen's parents who lost their son in middle age.

It wasn't a good time to ask, but Mo Tu chose to come to the door a little presumptuously to find two heartbroken white-haired people.

"I'm sorry to come to you again, I want to ask some more things about Chen Chen, and find out why he jumped off the building as soon as possible." Mo Ji said sincerely in the living room crowded with a bunch of people.

At present, Chen Chen's parents still don't know why their good son jumped off the building.

Chen's mother was depressed and seemed unable to communicate. Seeing this, Chen's father asked other relatives to take care of his wife, and then took Mo Zhi into Chen Chen's room.

Chen's father closed the door: "This is Chen Chen's bedroom. ”

Unpredictable saccades.

Chen Chen's bedroom is very clean, and the placement is relatively simple, from the unpredictable way into Chen Chen's house, it is easy to see that Chen Chen's family is not wealthy, and belongs to an ordinary family.

"Sit down." Seeing that Chen's father was pale, he hurriedly asked him to sit down.

After sitting down, Mo Tu asked straight to the point: "Can you tell me more about Chen Chen's situation?" ”

Chen's father sighed slowly: "My son is very well-behaved, he was a very lively child before he went to high school, and he liked everyone who saw him." At that time, my studies were not bad, so I was able to get into this school. The summer vacation after graduating from junior high school, he was found to have purpura, and he kept drinking Chinese medicine, and he was basically cured in his first semester of high school. ”

Unpredictable listened carefully.

Before the big right and wrong, he will not continue to maintain the state of being a leisurely and leisurely hanger, which is disrespectful to the deceased and disrespectful to Father Chen.

"When he went to high school, he lived in a dormitory for the first time, and he went home once a week. We can't urge him to study every night like before, and it is estimated that because of this, his academic performance has been declining and getting worse and worse. Later, his mother and I enrolled him in cram school, but to no avail, he didn't seem to be able to learn anything. As soon as he came home from vacation, he locked himself in his room, and rarely had the same communication as he did when he was a child, and he didn't understand what he was thinking about every day......"

Father Chen's voice was hoarse, and judging from his face, he seemed to be very remorseful.

"Listening to what you say, Chen Chen's junior high school was quite different from his high school days, right?" "There are two things at this point of change? One is that Chen Chen is sick, and the other is that he has started to stay? ”

"Yes." Father Chen nodded, "Maybe the pressure of studying is too much, and he has become a little introverted...... In addition, Chen Chen's weekly expenses are a bit large, and I don't know where he spends it. ”

"Expensive?"

"Hmm. I asked other parents about their children's expenses at the parent-teacher conference before, and they had less than 100 or 200 a week, and the food money was completely sufficient. But Chen Chen is different, he has to get at least 300 yuan a week, and 400 yuan when he has more. When asked why he spends so much in a week, he just said to eat. ”

"If he wants so much, you will give so much?"

Father Chen sighed again: "After he got purpura, there were a lot of things that he couldn't eat, and he became a little taboo. I went to high school, and it was my first time to stay, so I don't have a problem with giving more money, as long as the child eats better and supplements more nutrients to be healthier. If you have money to spare, you can use it as pocket money. Although the family conditions are not good, my mother and I will still try our best to satisfy the child and don't want him to suffer......"

The couple loved their children a lot.

Mo Ji was slightly disappointed.

Because everyone currently believes that Chen Chen died by suicide, when asking uncertainly, Chen's father will subconsciously think about why Chen Chen committed suicide, so the things associated with it are all the motives for Chen Chen's possible suicide.

For example, if you don't study well and have too much pressure.

But Mo Chao knew that Chen Chen was killed by him.

He chatted with Chen's father for a while, and he had a comprehensive understanding of Chen Chen. Because Chen's father's state was actually not much better than Chen's mother, and he needed to rest now, he didn't continue to ask and said goodbye early.

Back in the car, Mo Yu lit a cigarette and used the information given by Chen's father to try to find the murderer while smoking.

But there was no result.

After he finished smoking, seeing that the time was close to noon, he drove past a restaurant to pack some meals and returned to the bureau.
