"What accident?" Xiao Yi asked.

"Once when I sent my homework to the chemistry teacher's office, I accidentally saw that there were four people on the escort list, but my name was erased, why is it me, compared to my family and grades, I am no worse than Liu An, who was born in the countryside......" Zhang Liang said and became excited.

After a few minutes, he gradually calmed down, and then said: "That day, the chemistry teacher asked me to call Liu An, who was still resting in the dormitory, because at 7 o'clock he would conduct a small test on the four of us, and I just arrived downstairs in the dormitory to find that there was a power outage. Then as soon as he walked into the dormitory, he found Liu An sitting on a chair with his head tilted up, went up to try his breath, and found that he was dead.

At that time, I wanted to call the police as soon as possible, but when I thought that he actually replaced me to get a place on escort, I was very angry. I looked around, remembered the criminal investigation film I had watched, and dealt with the scene to create the illusion of suicide. Then I followed the fire emergency escape and left the dormitory building.

Because of the power outage, I wasn't worried that the surveillance would capture me, and when I returned to the classroom, I found that the other two people and the chemistry teacher were waiting for me, I looked at the time and saw that it was already 6:58, so I told them that I was there, and Liu An was not found in the dormitory, and you know what happened later. Zhang Liang closed his eyes with relief.

"When will the bell ring?" Xiao Yi asked.

"Ring 5 minutes early, 6:55." Zhang Liang said.

"Did you hear the bell on the way back?" Xiao Yi seemed to have thought of something and asked.

"I didn't hear it, but it rang at 7 o'clock, and the chemistry teacher said that there was a five-minute delay because of the power outage, and I didn't pay attention at that time." Zhang Liang thought for a while.

After Xiao Yi listened, he had a certain number in his heart, the murderer was Ouyang Tian, and the bell was not delayed at all, but he turned the time backwards.

Xiao Yi still had a question now, that is, why Ouyang Tian only made a move now, how could he kill the murderer in just a few minutes and then leave the scene.

Now that the time had reached 5:25 p.m., as soon as Zhao Wen came back, he received a notice from Xiao Yi asking him to go to school to monitor Ouyang Tian with Wang Jun.

Xiao Yi is going to a place now, and he wants to confirm a problem, because he feels that the truth will not be so simple.

casually coped with dinner on the side of the road, took a taxi to the place where Ouyang Tuohai, who committed suicide three years ago, lived, and by asking people nearby, he learned that the key to the room was in the hands of the janitor.

"Uncle, do you hear me?" Xiao Yi raised his voice and said.

The janitor turned his head and looked at Xiao Yidao: "Is there something wrong?" Offspring. ”

"I'm from the police station, and I came here today to see the room where the student who committed suicide three years ago lived, and I heard that the key is in your hand." Xiao Yidao.

"Oh, that room hasn't been rented anymore since it was rumored to have been inhabited by a suicide person, and it's been empty." As he spoke, the uncle took out a handful of keys from a bunch of keys and handed it to Xiao Yi.

"That kid is also a poor man, who comes to high school in the city alone, goes to school during the day, and goes to odd jobs at night, alas...... How could you not think of suicide. The uncle sighed, shook his head, and said.

"Uncle, take the liberty of asking, do you know what that kid's name is?" Xiao Yi faintly sensed something in his heart, and said with a puzzled tone.

"I think about it...... When I first came here, I remember it was called Altohai...... That's right, it's called Outuohai. The uncle thought for a while.

"Uncle, are you sure it's called Ou Tuohai and not Ouyang Tuohai?" Xiao Yi asked.

"I'm sure his name was Ou Tuohai when he first came, but there was a time when a man in a suit took him out every day, and I thought it was his father at the time, until one day he happily told me that he had changed his name now, and he would be called Ouyang Tuohai in the future: Ouyang Tuohai, and I told him at the time, aren't these two names the same? He smiled and didn't answer me. After the old man finished speaking, he was still a little puzzled.

Xiao Yi smiled and said, "Uncle, you rest and I'll go up and have a look." As soon as he walked up the stairs, the uncle behind him suddenly said, "Recently, a middle-aged man came over every night and went to that room."

Xiao Yi paused for a moment and asked, "Do you remember his face?"

The uncle smiled and took out his mobile phone and clicked on a photo. Xiao Yi saw that it was Ouyang Tian.

"Awesome, my uncle." Xiao Yidao.

Opening the door, Xiao Yi walked into the room, turned on the light, and saw that there was not even a little dust on the ground, and the surrounding furniture seemed to have been used recently.

Xiao Yi carefully looked at everything around him and found that there were a lot of friction marks on the doorknob of the door, just like someone opened and closed the door every day.

Walking into the room, turning on the light, I saw a huge whiteboard, which had the information of Liu An and all the people in their dormitory, as well as their plans.

Xiao Yi took out his mobile phone and called Wang Jun: "Arrest people directly, arrest them now."

"Team Xiao, you've found crucial evidence...... Wang Jun was pleasantly surprised.

"Well," Xiao Yi hung up the phone, took a few photos, and rushed to school.

At this moment, Wang Jun was in a stalemate with Ouyang Tian in the principal's room, because he had no evidence, everything was speculation, and he had no way to arrest people, so he could only wait for Xiao Yi to arrive.

Outside the school gate, police lights lit up the street next to it, and it was 7:10 p.m.

It was already past 8 o'clock when Xiao Yi rushed over, and after thinking all the way, he finally found the key evidence.

"You can't arrest me without evidence, or I can go to court to sue you." Ouyang Tian said lightly.

"Who said there was no evidence......"

Xiao Yi walked into the principal's office with a black plastic bag and said.

"Captain Xiao, what about your evidence?" Ouyang Tian said with a smile.

opened the plastic bag, there was a white towel in it, and an alarm clock, and casually opened the phone to show him a few pictures.

Ouyang Tian looked at these things, his momentum disappeared in an instant, as if he was dozens of years old, he raised his head and looked at Xiao Yi and said: "Sure enough, the rumors from the outside world are true, you are still the same Officer Xiao, I have done it seamlessly, but I didn't expect ......"

"Go to the police station and say, Wang Jun, take it away." After Xiao Yi finished speaking, he turned around and left, throwing the things in his hand to Zhao Wen on the side.

A mobile phone rang, Xiao Yi picked up the phone and saw that it was Liu Ruoyun.

"Team Xiao, the identification results are out, I compared the DNA from three years ago with the hair you brought, and there is no blood relationship, but ......" Before the words were finished, Xiao Yi continued,

"Liu An's DNA is as similar as 90% to the DNA of the hair owner, it can be determined that it is a father-son relationship, the hair is Ouyang Tian, and Liu An is his son."

"Team Xiao, did you already know, just asked me to collect evidence so that Ouyang Tian could confess, but he shouldn't know that he killed his own child." Liu Ruoyun said in a somewhat frivolous tone.

As soon as he returned to the police station, the technical department handed Xiao Yi a video material, and after reading the information, the corners of Xiao Yi's mouth were slightly hooked and said: "It's a little late......"

Zhang Jing said on the side: "What's late?"

Xiao Yi directly threw the information to Zhang Jing and said, "See for yourself."

Zhang Jing found that the information showed that every time the school had a power outage, it was Ouyang Tian who took the electrician to repair it, and every time he could find the place where the fault occurred in the shortest possible time. There is no doubt that the murderer who caused the power outage was Ouyang Tian, who finally found a suitable opportunity after a month of testing......

At this time, Wang Ju heard that the murderer had been caught, and rushed back directly from the city, he was under a lot of pressure in the past few days, if he couldn't catch the murderer again, he should go down from this position. So he directly released Xiao Yi from the archives, even if Xiao Yi has a split personality, he can accept it.

Forensic doctor Liu Ruoyun applied to be interrogated with Xiao Yi because he had always had a question about how Ouyang Tian killed the murderer in such a short time and returned to the classroom, and how did he do it.

"Ouyang Tian, I won't leave the process, you can say it yourself...... Take the initiative to admit that I still recognize you as a man. Xiao Yi said lightly.

"Hmph, you go to that place, otherwise you wouldn't have found that towel." Ouyang Tiandao.

"Let me tell you the unfortunate news, the Liu An you killed is the Ouyang Tuohai you have been looking for, and it was not Ouyang Tuohai who committed suicide three years ago but Ou Tuohai, you have been deceived." Xiao Yi didn't want to waste time with him and said directly.

"Impossible, you lied to me, is it Tuohai I don't know, want to use this method to let me recruit, impossible." Ouyang Tian's tone suddenly became a little excited.

Forensic doctor Liu Ruoyun walked in front of him. took out three pieces of DNA for identification and said lightly: "The evidence is here, you can see for yourself, I just compared."

Ouyang Tian looked at the report carefully, and muttered unlistened: "Impossible, you lied to me, how could I kill my own child, impossible...... It couldn't be ......."

"Don't lie to yourself, this is the truth, Ouyang Tian, you are a poor worm, you have been played with by others." Xiao Yi's tone suddenly became serious.

After about 3 minutes, Ouyang Tian, who had calmed down, suddenly laughed, and he laughed and cried.

"A year ago, I had just returned from studying abroad and received a message from a stranger. He told me that my child was forced to die, and he didn't believe that I could go to Yucai High School to investigate. Then I went to Yucai High School through a relationship, and after a year of investigation, I locked down the main 4 murderers.

It took me nearly 6 months to find the clues, and finally found where Ou Tuohai lived, and found a diary in his room that recorded everything in detail, and then I began to plan to kill Liu An and the four of them.

Finally, a few days ago, I found an opportunity, I adjusted the time of the school's evening bell back for 5 minutes in advance, and then notified the three of them to take the test, and I have been hiding in the utility room behind Liu An's dormitory on that floor.

I calculated the timing of the power outage, called Liu An to the utility room, suffocated him with a towel, and then dragged him to his own room, along the window, and I jumped straight down.

When he returned to the office, he informed Zhang Liang, one of the three of them, to call Liu An over. Because the power went out 10 minutes early, I had plenty of time.

I took advantage of their inattention, and shifted the time of the alarm clock used for the test reminder, and then the preparatory bell rang on time, so that they would not notice that it was 5 minutes missing.

And Zhang Liang was deliberately let him pass, because he has always looked down on Liu An, and if he sees Liu An's death, he will definitely cover up the traces for me. The rest of the matter is known to Team Xiao. ”
