Mystery

Shen Ke was really surprised this time, to be honest, Li Yuan has always played the role of a gun with her.

It works, but someone has to use it.

Li Yuan took a look at her expression, and immediately understood, "Old Shen, have you underestimated me? I used to be the team leader, but now I've retired and decided to cultivate myself and become a sweeping monk."

Shen Ke gave Li Yuan a white look, "This is not the top floor, don't worry about blowing the ceiling, you can blow it hard. What's the result of the investigation?"

Li Yuan fumbled in his pocket, and found out a folded piece of paper.

Shen Ke leaned over and took a look, it was a simple combat map drawn by Li Yuan.

Although it is a simple version, it is surprising that Li Yuan's map is drawn very well, like someone who has professionally studied surveying and mapping.

"Although I very much hope that Liu Yuanming is a good person, his alibi is indeed flawed."

Li Yuan said, pointing to a small red dot in the newspaper group, "Liu Yuanming's office is on the northeast corner of the 7th floor. It hasn't been moved for several years. Like Team Chen, he is the editor-in-chief and has his own separate office."

"According to the confession, Liu Yuanming worked overtime that night until 11 o'clock in the evening. But because he was not in an office, no one was watching him at all. He only needs to show up in the big office at 11 o'clock, or meet other people who are off work. With that alibi."

"If Liu Yuanming used his intern card to get in and out, or followed others in and out, there would be no record of swiping his card. His alibi looks very powerful, but it's actually a show, vulnerable to a single blow."

"Also, I've inquired. The editor-in-chief has a temporary access card, which is for that kind of interns. Because the interns are rotated very quickly, there is no real-name system."

So in that case, Liu Yuanming just needs to show that he never met Bao Hui at all.

Li Yuan pointed to the little red dot's hand and paused, then came to his senses belatedly, "I'll go! It's true!"

"But here comes the problem. Between 10:15 and 10:30, the camera in the coffee shop took pictures of the road from the alley to the intersection in front. After the intersection, go back a little and you will report Industry Group Building."

Shen Ke looked at Li Yuan's gestures, and instantly understood what he meant, "So Liu Yuanming can take the elevator, or go down the fire escape. As long as no one comes to look for him, he will think he is in the office all the time."

Why did he go to such lengths to provide the card swiping records in the building, as well as the confession of his colleagues, as his alibi?
Shen Ke's cell phone dinged at this time, she looked down and said to Li Yuan, "I asked Zhang Yang, and he said that Liu Yuanming offered it."

"There are two doors in the building. One is the main entrance, which can be entered by swiping a card, and there are security guards. The other is a small side door, which can be entered and exited by swiping a card, but there is no security guard."

Officer Shen, can you give me a way out at night?

As he spoke, he continued to look at his map, speaking more solemnly.

Li Yuan said, pointing to himself, "Your building also has a separate entrance, but I followed others in without ringing your doorbell. Liu Yuanming is also fine."

Hearing this, Shen Ke looked Li Yuan up and down, "You are quite predictable about your own future life."

If Zhang Sijia hadn't said there was something wrong with Liu Yuanming, and if Grandma Wang hadn't remembered that Bao Hui had called the teacher, they wouldn't have listed Liu Yuanming as the main suspect.

"The elevator is in the middle, Liu Yuanming's office is on the right side of the elevator, and the big offices of other editors and reporters are on the left. There are fire-fighting ladders on both sides of the building."

"Before 10:30, enter the alley. Then at 10:45, after finishing the work in the alley, return the same way. Bao Hui is a big living person, how can he disappear?"

"The teacher didn't want to be caught by the camera as he entered the alley. He just needed to enter before 10:15 to 10:30. There was no mention in the file that someone had entered the alley, so it was not photographed."

"That will also be caught by the camera at the entrance of the cafe."

"Today we met that police officer Zhang Yang. He is quite rough in handling the case. At that time, the monitoring of the coffee shop showed that Bao Hui did not go to the newspaper group, and Liu Yuanming was not a criminal suspect."

As Shen Ke said, she put her car keys on the blueprint drawn by Li Yuan, "So, walking is not allowed, and you will be photographed. But you can drive. Go out from the side door of the newspaper group, get into a car, and then Pass the cafe door, take a detour, turn around and come back."

Li Yuan is a joke.

"The alibi Liu Yuanming gave at the time included no record of him checking in and out, and the security guards did not see him."

"Obviously the restaurant with the side door is even more suspicious. There is no alibi for them in the file. Why does Liu Yuanming have one?"

"Carrying it? It's impossible to carry it on your back. If you have a car, it will be convenient."

"That is to say, Zhang Yang and the others didn't really regard him as a suspect back then, so they didn't investigate further."

"That is to say, from 10:30 to 10:45, the camera was shooting at the alley."

Shen Ke nodded, "So he can get down unimpeded. The camera in the coffee shop changes direction every 15 minutes. Bao Hui got off from No. 10 at about 40:778, walked for a few minutes and entered the alley, about 10:45 , the camera switches, and the alley is no longer photographed."

Li Yuan was a little speechless, he smiled wryly, "Why does it have a taste of trying to cover up?"

Shen Ke listened and interrupted Li Yuan, "First of all, it's strange that he has an alibi."

"If the teacher wants to enter the alley from the newspaper building at this time, then he will take pictures of the whole section of the road after the intersection. If he doesn't take that section, walk along the side of the cafe, and then cross the road .”

Seeing that Shen Ke had finished his meal, Li Yuan said confidently and boldly, "Even if someone came to him and found that he was not there, it would be easy to make up his mind automatically. For example, a middle-aged man with constipation squatted in the pit for half an hour, and sighed in the fire escape." Depressed life."

"After returning to the newspaper group, I clocked out at 11 o'clock, but after going out for about 10 minutes, no one would have thought that someone would do such a big event."

Li Yuan opened his eyes wide, and he shook his head, "I didn't think about how to transport Bao Hui away, so I didn't think about the car. I tried it myself today, and I can walk."

"The small side door of the newspaper group is actually similar to the back door. There is no camera there. You can go around the building, then cross the road, and go in when the camera is not shooting the alley. After the camera moves away, Back on foot again."

Shen Ke heard the words, and thoughtfully took the car keys away.

"Whether there is a car or not, there are at least two things that are certain. First, Liu Yuanming's alibi was overturned; second, the teachers of the newspaper group had the time and ability to commit crimes."
