With the continuous change of the surveillance screen, it can be seen that Liu Chen, the victim of the '8.09 case', took Xun He's hand and walked into the elevator first.

After that, the man named Weng Tao also walked in with the people around him.

Xiao Ran found the surveillance screen in the elevator at that time, adjusted it to the time point recorded, and could see that in the elevator, because Liu Chen and Xun walked into the elevator first, the two of them were standing behind.

Weng Tao walked in later, standing in front of the two, and Weng Tao didn't pay attention to them at first.

With the improvement of the elevator, the people in the elevator kept coming out, and the number of people became smaller and smaller, and finally only Weng Tao and Liu Chen, Xun or three people were left in the elevator, and at this time, Liu Chen leaned on Xun or and grinded his ears and temples, as if he was talking about something coquettishly.

Weng Tao finally noticed the pair of abnormal men and women with a huge age difference behind him, he turned his head and glanced at Liu Chen and Xun Or a few times, but Liu Chen was in love with Xun He and completely ignored Weng Tao.

It can be seen from the surveillance footage in the elevator that Weng Tao pursed his lips, showing a thick disdain and disgust on his face.

The elevator arrived at the floor where the restaurant was located, and after the door opened, Weng Tao stood in front of him, and he should have been the first to walk out, but he paused for a while, and only after Liu Chen and Xun He went out, Weng Tao followed the two out.

Noting down the time, Xiao Ran switched to the monitoring of Weng Tao and the others walking into the western restaurant.

Then you can see that the waiter took the lead in guiding Liu Chen's Xun or sat down in a position, and Weng Tao seemed to walk in the back casually, choosing a position very close to Liu Chen and them.

Although Weng Tao seemed to have been looking at the menu, from his absent-minded expression, Xiao Ran judged that Weng Tao had been eavesdropping on Liu Chen's conversation with Xun He.

Time passed little by little, Liu Chen and Xun or the two of them were even more spicy when they were eating, and the two of them just fed each other, and the key was to kiss from time to time, completely ignoring the strange eyes of the surrounding diners.

Weng Tao was sitting precariously, eating the food in front of him very solemnly, his eyes looked at Liu Chen from time to time, and the disgust on his face became more and more intense.

During this period, Weng Tao ordered another cup of coffee, but he seemed to be very unaccustomed to drinking, took a sip, forcibly drank it, and then added several packets of sugar to it.

It was only then that the situation finally changed.

Xiao Ran saw Liu Chen answer a phone call, it should have been Liu Chen's best friend calling.

Sure enough, just after Liu Chen spoke to the phone for a while, Weng Tao opened the notebook without a trace, took out a pen from his pocket, and wrote down a paragraph.

- That should be the rental address that Liu Chen told his girlfriend on the phone.

After Liu Chen and Xun Or checked out, Weng Tao also paid immediately, followed Liu Chen and them downstairs before and after, Xiao Ran kept switching the surveillance screen, only to see Weng Tao holding an umbrella, following Liu Chen and Xun Or to the entrance of a hotel.

Seeing Liu Chen and Xun Or enter the hotel, Weng Tao stood on the side of the road with his head down for half a minute, and then he raised his hand to stop a taxi and left.

Xiao Ran wrote down the license plate number of the taxi.

Although Xiao Ran vaguely remembered that this person's name was Weng Tao, and when he saw him before, he seemed to be dressed as a migrant worker, but Xiao Ran didn't know anything about where this person lived and what the specific situation was.

And yesterday Weng Tao watched Liu Chen walk into the hotel holding Xun He's hand, he should have been murderous at that time, but Weng Tao did not have the tools to commit the crime at that time.

Therefore, Xiao Ran judged that when Weng Tao took a taxi to leave, he should have gone back to his residence to prepare tools.

The taxi driver probably remembered where Weng Tao lived, or settled in a certain area.

Seeing this, the matter of Liu Chen and Xun Or came to an end for the time being, but the victims of the '7.28 case', Li Lu and her husband Cheng Yuguo, and Weng Tao behind them, appeared in the surveillance screen at an exit of the park.

It was the evening of July 27th, and it hadn't rained yet, Cheng Yuguo walked out of the park with his daughter and his wife Li Lu.

Weng Tao followed behind them.

However, Weng Tao was not so solemn at that time, just wearing a half-worn T-shirt, wearing a pair of shorts, stepping on double flip-flops, a little uneasy, and a little excited hanging behind Cheng Yuguo and Li Lu.

The picture then turned to the road surveillance, Weng Tao was still following Cheng Yuguo and his wife without a trace, but when the road was halfway through, it suddenly rained, Cheng Yuguo and Li Lu quickly walked down the road and walked into the path without surveillance.

Weng Tao stood at the intersection and looked left and right, his expression became more and more happy and excited, and then he also walked into the path.

Xiao Ran looked coldly at Weng Tao, who disappeared from the surveillance, he was now sure that his previous judgment was not wrong, Weng Tao was looking for the target of the crime immediately, and he did it in the shortest possible time.

Weng Tao followed Cheng Yuguo and his wife, and it should be to determine the location of their home.

After Weng Tao got the address of the rental house and heard that Liu Chen would go over to clean up in the evening, he did not return by car until Liu Chen and Xun He came out of the hotel.

Thinking about it, he should have gone back and brought the tools of the crime, so he went directly to the location of the rental house that Liu Chen said, and laid an ambush in advance.

After Xiao Ran marked the important time points on the monitor, he moved his stiff neck and looked at the time, it was already more than 12 o'clock in the night, and unconsciously such a long time had passed.

With the bottom in his heart, Xiao Ran was about to call Captain Zhang Hui, but Yu Yu's phone call came first.

"Did you get the DNA extraction?"

Xiao Ran asked directly, after all, Yu Yu called at this point in time, and it must have been the results of the residues sent for testing in the morning.

Yu Yu's voice was mixed with a hint of tiredness, but his tone was still very cheerful: "A good news, a bad news, which one do you want to listen to first?"

"Bad news, I like bitter before sweet. Xiao Ran said.

Yu Yu snorted and said, "The bad news is that I haven't slept for two days and one night, and I feel like my whole person is about to float to the sky." - I seriously doubt that I am a little fairy who has gone down to the mortal world, and now I am going to return, and you will never see me again, is it a bolt from the blue?"

"It's a cloudy day. In addition, my heart did not fluctuate, and I was even very happy. Xiao Ran said calmly.

“...... You go!"

Yu Yu gritted his teeth for a while, calmed down for a while before saying: "The good news is that we, the technologists, have successfully extracted DNA from the food residues you sent, and we are now comparing it in the database, but it has been determined that this DNA data does not belong to Cheng Yuguo or the deceased Li Lu." ”

"Thank you, thank you, thank you for your hard work, I'll send you ice cream back. Xiao Ran thanked.

"Okay, then I won't tell you, I'm going to catch up on sleep!"

After talking to Yu Yu, Xiao Ran looked at the phone screen and took a deep breath, it's time to find the one named Weng Tao!
