But it's a pity that in the video, the police only saw Zhang Yue alone, she walked to the main entrance of the building one by one, because of the blind spot of monitoring, the police couldn't see how she opened the door. Pen % fun % Pavilion www.biquge.info

The building's administrator watched the video and said with certainty, "Someone opened the door for her!"

Indeed, this is not difficult to see from the video, because Zhang Yue's movements are very smooth, without any pause in between, so the only explanation is that someone in the building opened the door for her at that time.

The police see this. Immediately ask the building administrator, "Who else has the key to the door besides you?"

The building administrator thought for a moment and said, "There are many people who have the keys to this building, me, the principal, the dean of students, and the director of logistics, ......."

The police saw that so many people had the keys to the building, but through subsequent investigation, it was found that these people had alibi.

First of all, the building administrator, because the laboratory building was not open that day, he was helping out in the student dormitory that day. The logistics director had been busy in the school cafeteria that morning, because the school would cook another meal for the senior high school students at noon that day. As for the principal and the dean of students, they were in a meeting with a few teachers at that time.

This immediately ruled out everyone's suspicions, but there was still no clue why Zhang Yue came to this building alone. At this time, the words of the building administrator attracted the attention of the police, and he said that in addition to the keys to the building in the hands of these people, the squad leaders of each class would also borrow them temporarily.

Because their school stipulates that if each class wants to use the laboratory, it must be cleaned in advance, so it is usually borrowed by the class leader of each class from the administrator of the building, and then returned after it is used up.

When the police noticed this clue, squad leader Yuan Tengfei jumped into the sight of a policeman. When he called Zhang Yue before, he asked her about her college entrance examination results, could it be because he was jealous, so he killed her?

However, when the police investigated Yuan Tengfei's background, they found that he was a very good student, not to mention his good grades, and he won many awards during his time in school, such as three good students, outstanding student cadres, and outstanding league members...... He has also won the title of the top ten middle school students in the city.

With such an excellent student in all aspects, it is really difficult to get him involved with the suspect. But...... When the police investigated the squad leader Yuan Tengfei more deeply, they found a lot of other sides that he didn't know.

The police investigated some of the websites that Yuan Tengfei had followed through the Internet supervision department, and found that they were all websites that exaggerated bloody violence. He even logged on to a website called "Murder" several times to watch some real videos of brutal violence and even rape.

The police were particularly shocked at that time, they really didn't know what happened to the children now? Under the glamorous and gorgeous appearance, there was a real personality that was so perverse, perverted, and violent.

At first, the police did not directly find Yuan Tengfei, and continued to investigate among their classmates, and Yuan Tengfei's traces on the day he returned to school...... As a result, several classmates said that after 11, they had not seen the class leader, and the head teacher still wanted to find him at that time, but the phone call was never available.

And another clue has also greatly increased the suspicion of Yuan Tengfei, that is, the college entrance examination results of the two people!

In normal times, the results of the two can be said to be equal, and every time you take the exam, you chase me, one after the other. However, this time, Yuan Tengfei's score in the college entrance examination was nearly 30 points behind Zhang Yue! If Yuan Tengfei's heart did not fluctuate at all, it would be impossible!

In order not to startle the snake, the police did not contact Yuan Tengfei directly, but let a psychologist contact him first. The psychiatrist said that Yuan Tengfei was a child with strong thinking ability, and his logical and cognitive abilities were stronger than ordinary people, and no matter how the test results were obtained, he should be a good teenager with mental health and optimism.

At this time, the case had been transferred to Bai Jian's hands, he knew that this time should be the time to contact Yuan Tengfei head-on, he thought that a student who was less than 20 years old, the psychological defense line should not be too strong, with his years of experience in handling cases, it should be very easy to break through.

Unfortunately, he was wrong......

When Yuan Tengfei saw Bai Jian's first face, he was not nervous at all, and calmly responded to Bai Jian's question, and his answer could be said to have no loopholes.

Regarding his whereabouts after 11 o'clock that day, Yuan Tengfei explained that he had a stomachache at that time, so he went to the toilet, but he still felt uncomfortable afterwards, so he went back to the dormitory and sat for a while.

Seeing that Yuan Tengfei was so difficult, when Bai Jian put the accounts of some of the websites he browsed and registered in front of him, Yuan Tengfei was immediately silent after reading it, but Bai Jian still couldn't see any nervousness on his face.

After a short silence, Yuan Tengfei actually asked for a lawyer. At that time, Bai Jian wanted to laugh when he heard this, wondering if this kid had watched too many movies? He was still looking for a lawyer! But Yuan Tengfei's attitude was very resolute, and he offered to let him meet his parents if he didn't find a lawyer.

In the end, the police considered that there was no substantial evidence pointing to Yuan Tengfei as a suspect, so they had to agree to his request to let his parents meet him, of course, under the premise that the police were present.

Yuan Tengfei's parents were very emotional when they came to the police station, and they couldn't understand why the police had brought their son here, although Bai Jian repeatedly explained that it was only to cooperate with the investigation, not a summons. However, Yuan Tengfei's parents said that their son had been admitted to a key university, and they did not want to have any bad impact on Yuan Tengfei because of the mistakes of the police......

Bai Jian also understands his parents' feelings, but judging from the current clues, this Yuan Tengfei's suspicion is really big, and before Zhang Yue is found, the police must stare at him.

At this time, the colleagues of the Internet Supervisor found a blog by Yuan Tengfei under the pseudonym "Tyrannical Monarch", and all the words he expressed on it were filled with a large number of videos about how to torture, detain, rape, and even eat corpses......

Although these texts and videos have been banned by the website, there were also many likes and reprints when he uploaded them that day, and the blog was quickly banned.
