Shen Ke was really surprised this time. To be honest, Li Yuan had always been a one-man weapon with her.

It's easy to use, but someone has to use it.

Li Yuan took a look at her expression and suddenly understood, "Old Shen, you're looking down on me, aren't you! I used to be the captain, but now I've retired and decided to cultivate myself and become a sweeper."

Shen Ke rolled his eyes at Li Yuan and said, "This is not the top floor. Don't worry about blowing the ceiling. You can blow hard. Where are the results of the investigation?"

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

Shen Ke came over and took a look. It was a simple combat map drawn by Li Yuan.

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

"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 in the northeast corner of the seventh floor. It has not been moved in several years. Like Captain Chen, he is the editor-in-chief and has his own separate office."

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

Shen Ke listened and interrupted Li Yuan, "First of all, it's very strange that he has no alibi to prove this."

Li Yuan pointed at the hand with the little red dot and then realized after a while, "I'll go! It's true!"

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

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

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

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

Why go to such trouble to provide the credit card records in the building and the confessions of his colleagues as his alibi?

Shen Ke's cell phone dinged at this time. She lowered her head and said to Li Yuan, "I asked Zhang Yang and he said it was Liu Yuanming who provided it on his own initiative."

Li Yuan was a little stunned. He smiled bitterly and said, "Why does it have such an overpowering taste?"

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

"The elevator is in the middle, Liu Yuanming's office is on the right side of the elevator, and the large offices of other editors and reporters are on the left. There are fire escalators on both sides of the 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 see him, they will think that he is always in the office."

Seeing that Shen Ke had finished eating, Li Yuan said calmly and boldly, "Even if someone comes to see him and finds that he is not there, it is easy to automatically make up his mind. For example, a middle-aged man with constipation squats in a pit for half an hour and smokes in the fire escape to sigh. A miserable life.”

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

A piece of Li Yuan.

Officer Shen, can you give me a way to survive this late at night?

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

"The alibi Liu Yuanming gave at the time included that there was no record of him clocking in and out, and the security guard did not see him."

Li Yuan said, pointing to himself, "Your building also has a separate access control, but I followed others in without ringing your doorbell. Liu Yuanming can do it too."

"Besides, I asked around and found that the editor-in-chief has a temporary access card for interns. Because the interns rotate very quickly, there is no real-name system."

"If Liu Yuanming uses an intern card to enter or exit, or follows others in and out, there will be no card swiping record. His alibi looks very powerful, but in fact it is just a showmanship and vulnerable to attack."

"That is to say, Zhang Yang and the others did not really regard him as a suspect, so they did not investigate further."

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

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

"The teacher didn't want to be caught by the camera entering the alley. He just had to enter before 10:15 to 10:30. The file did not mention that anyone entered the alley, so it was not captured."

"But then a problem arises. Between 10:15 and 10:30, the coffee shop camera captured the section from the alley entrance to the intersection in front. After passing the intersection, walk back a little, which is where the police station is located. Industrial Group Building.”

"If the teacher wants to enter the alley from the newspaper building during this time, then the entire section of the road where he passes the intersection will be photographed. If he does not take that section of the road, he will walk along the side of the cafe and then cross the road. .”

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

Shen Ke said, putting his car key on the drawing drawn by Li Yuan, "So, if you can't walk, you will be photographed. But you can drive. Come out of the side door of the newspaper group, get in a car, and then Pass the entrance of the cafe, take a detour, and turn around and come back."

"Enter the alley before 10:30. Then at 10:45, after finishing things in the alley, return the same way. How can Bao Hui, a living person, disappear?"

"Carrying it on your back? It's impossible to carry it on your back. It would be more convenient if you have a car."

"After returning to the newspaper group, I clocked out at 11 o'clock, but I was out for about 10 minutes. No one would have thought that someone had done such a big thing."

Li Yuan's eyes widened and he shook his head, "I didn't think about how to transport Bao Hui away, so I didn't consider a car. I tried it myself today and it's OK to walk."

"The small side entrance of the newspaper group is actually almost the same as the back entrance. There are no cameras there. You can go around the building in a circle, then cross the street, and go in when the cameras are not filming the alley. Then after the cameras move away, We walked back the same way."

Hearing this, Shen Ke took away the car keys thoughtfully.
