Yu Ping'an felt that Liu Shan's case still had many doubts.

"When was the last time the eldest brother went to Liu Shan?"

Yu Ping'an asked.

"The eldest brother spent the night at Liu Shan's place on Friday, and the eldest brother should not have been here on Saturday and Sunday, at least I didn't find out that he came."

Chen Shiling thought back to the situation in the past few days.

"The current situation is that the wine bottle has the fingerprints of the eldest brother, which means that the eldest brother must have touched the wine bottle, but it does not mean that the sleeping pill is the eldest brother put in the wine."

Yu Ping'an said his thoughts.

"Yes, yes! Maybe she put it herself? ”

"After the eldest brother left, has anyone been to Liu Shan's house on Saturday and Sunday?"

"I didn't pay much attention to this, I usually pay attention to the movements of my eldest brother."

"It's okay, let's go to the property to check the elevator monitoring and see who has been to the 9th floor."

"Brother Ping An means that someone else put sleeping pills in the wine?"

"It's very likely!" Yu Ping'an continued, "There is another thing, that is, Liu Shan contacted the eldest brother before he died, in order to force him to death. It is estimated that she thinks that after the eldest brother receives the information, he will go to her. Unexpectedly, the eldest brother only went to look for her in the morning, so that she was already dead at that time. But why did the eldest brother go to see Liu Shan only in the morning, instead of seeing her immediately after receiving the message? ”

"Maybe you didn't see it, right?"

Chen Shiling guessed.

"Now that everyone is in the habit of using mobile phones, will they not look at their mobile phones all night?"

Yu Ping'an felt that this situation was unlikely.

"That's right! At least play with your phone for a while before you go to bed! ”

"Of course, it can't be ruled out that I was too busy and really didn't see the information, but there is also a possibility that someone deliberately didn't let the eldest brother see the phone."

"Why would this person do this?" Chen Shiling showed a look of surprise, "Could it be that this person wants Liu Shan to die?" ”

"Yes! This person may be the initiator of Liu Shan's mistaken sleeping pills! ”

Yu Ping'an said his inference.

"That means who Big Brother is with on Sunday night, and who is the suspect?"

Chen Shiling suddenly realized.

"The premise is that the eldest brother really doesn't know about Liu Shan's taking sleeping pills."

Yu Ping'an added.

"It won't be really a big brother ......"

At this time, Chen Shiling was very worried in her heart, and she was not sure that Chen Zhiren must be innocent.

"Although the suspicion of the eldest brother cannot be completely ruled out now, I think it should not be the eldest brother's doing."

"Why?!"

Chen Shiling asked eagerly as if she had grasped a life-saving straw.

"If it were me, with all the previous arrangements already realized, there was no need to venture back to the site to confirm! Because if Liu Shan hadn't died, she would just think that she had fallen asleep because of the sleeping pills she was taking. If he dies, his goal has been achieved, and there is no need to return to the scene to increase his suspicion. ”

Yu Ping'an did not deliberately comfort Chen Shiling, but just objectively said his thoughts.

Chen Shiling's expression was a little relaxed, and she nodded.

"Let's go check the monitoring first!"

Yu Ping'an proposed.

……

Since Liu Shan's house did not install surveillance, it could only be checked through the surveillance video of the elevator.

So the two went to the property of the community to check the surveillance in the name of losing something.

"Look! This guy went to the 9th floor! ”

Yu Ping'an was the first to discover the situation.

Chen Shiling hurriedly came to the computer screen and looked at the person on the screen intently.

"Schelle!"

"Do you know this person?"

Yu Ping'an asked.

"I've seen it! It's Liu Shan's friend, or a little star. ”

Chen Shiling said.

Yu Ping'an then looked at the surveillance video and fell into thought at the same time.

After watching the entire video, Yu Ping'an and Chen Shiling found that from the time Chen Zhiren left Liu Shan's residence to the time Liu Shan was found dead. A total of 3 people have been to the 9th floor, and 2 of them are couriers and takeaways.

It took about 3 minutes from leaving the elevator to returning to the elevator.

After the courier left the elevator, he didn't come back.

Liu Shan's best friend Xie Lin took about 2 and a half hours from getting off the elevator to leaving.

"Why didn't the courier go back to the elevator? Could it be him! ”

Chen Shiling was a little puzzled.

"Wouldn't it be that Shailene?"

"We've met Xie Lin a few times, she's a little star, and she has a very good relationship with Liu Shan, why did she kill Liu Shan?"

Chen Shiling didn't think it would be Xie Lin.

"However, judging from the situation at the scene, it should be an acquaintance who committed the crime!"

Yu Ping'an felt that the possibility of a courier was not very likely.

"Could the courier be delivering wine with sleeping pills?"

Chen Shiling guessed.

"Didn't the big brother bring that wine?"

"That's right!"

"But what Shiling said is not impossible, we have to find a way to find the courier to confirm."

Both of them were stuck in their train of thought.

"It seems that we still have to wait for the results of Officer Liu's investigation!"

Chen Shiling, who was helpless, said.

Yu Ping'an nodded approvingly.

……

After the lawyer met with Chen Zhiren, Chen Shiling's words were conveyed.

In fact, Chen Zhiren had already realized that the situation might be a bit serious, otherwise he would not have been left in the police station for two days.

After meeting with the lawyer, Chen Zhiren completely stopped reporting any illusions, it doesn't matter what lovers or scandals there are, the most important thing now is to prove his innocence.

Chen Zhiren said that he would cooperate with the police investigation, and also explained the whole incident to his lawyer.

After the meeting, the lawyer immediately found Chen Shiling.

"Lawyer Wang, how is my brother?"

Chen Shiling asked anxiously.

"Mr. Chen is doing well at the moment, but he is a little anxious."

The lawyer put on a professional serious face.

"What did my brother say!"

"Mr. Chen said that he would cooperate with the police investigation."

Then the lawyer relayed what Chen Zhiren said to Chen Shiling.

It turned out that Chen Zhiren spent Sunday at another woman's place, and since the woman had been pestering Chen Zhiren, Chen Zhiren had been with the woman all night and did not pay attention to the situation on his phone.

It wasn't until Monday morning that Chen Zhiren found that his phone had been turned off, and when he turned on his phone, he saw the message from Liu Shan.

The message probably said that Chen Zhiren would die if he couldn't give her a name, and he also sent photos of sleeping pills.

At that time, Chen Zhiren was very panicked and worried, so he immediately drove to Liu Shan's residence.

But when Chen Zhiren came to Liu Shan's residence, he found that Liu Shan was dead.

Chen Zhiren was frightened, and after some ideological struggle, he finally chose to flee.

"Mr. Chen said that he didn't dare to move anything at that time, just to confirm Liu Shan's situation, he touched Liu Shan."

"Does the eldest brother know about Liu Shan's pregnancy?"

"Mr. Chen said he didn't know about it!"

"In this way, the motive of the eldest brother to kill is not sufficient!"

"I just don't know if the police will believe Mr. Chen's words."

The lawyer is not worried, after all, these are Chen Zhiren's words, Liu Shan is dead, and there is no evidence of death.

"Where's the door? Did the eldest brother forget to lock it when he left? ”

Chen Shiling asked.

"Mr. Chen didn't say anything about this, I'll confirm with Mr. Chen next time."

"Okay, who's that woman? Did the eldest brother say it? ”

"That's it! It's a little star named Shailene! ”
