It was rainy and dark early, Xiao Ran put down the thick pile of interview records in his hand, stood up and moved his body.

stared at the light outside the window for a while, and suddenly, Zhang Lei pushed open the door and walked in, asking, "How did you look, did you find anything?"

"I'll just take a look. If there's something really wrong, you should have noticed it when you visited. Xiao Ran turned around and replied.

Zhang Lei grinned and said, "Come on, I still don't know you for so many years? ”

Xiao Ran smiled at the same time, he just wanted to quickly go through the neighbors around Cheng Yuguo's house when he read these records, after all, the possibility of acquaintances committing crimes still exists.

But after reading it again, I didn't find anything, so naturally I didn't bother to say it.

"By the way, Shen Quliang and they have already turned the monitoring back, do you want to go and see it?" Zhang Lei said again.

"Of course. ”

Xiao Ran picked up the pile of transcripts on the table, walked out of the conference room with Zhang Lei, and after handing over the transcripts, he came to the audio-visual data inspection room of the Chengdong Branch.

The audio-visual room of the Chengdong Branch is not as large as the technical center of the Municipal Bureau, but it is enough, at this time, several visual police officers are checking the copied surveillance video, Zhang Hui, Shen Quliang and others are standing behind them and watching quietly.

"Brother Zhang, Leizi and I will also come to help, I am familiar with all of this. Xiao Ran walked over and said.

Zhang Hui looked at Xiao Ran, and said with a smile to Shen Quliang beside him: "I didn't expect that our Xiao Ran is still an all-rounder, and the criminal investigation technique is seamless!"

Zhang Lei smiled and continued: "Brother Zhang, you don't know, Xiao Ran can do a lot, on-site investigation, audio-visual inspection, note identification, and even help with an autopsy, I don't know when he will do this, he must have secretly gone out to make up for classes when he was in school." ”

"You sleep in my bunk, don't you know if I make up for the class?"

Xiao Ran smiled slightly, turned on the computer and said to the technician next to him: "Hey brother, give me a copy of all the surveillance." ”

"Okay. ”

Seeing that Xiao Ran and the others had already entered the state, Zhang Hui patted Xiao Ran on the shoulder and said, "Then you watch first, let's go do other things first, call me at any time if there is anything, anyway, no one wants to sleep tonight." ”

"Okay. ”

Xiao Ran nodded, watched Zhang Hui, Shen Quliang and others leave the audio-visual room, and then took over the copy of the relevant monitoring, and looked at it with full attention on the two split screens according to his own unique rhythm.

On the two screens, one is the monitoring of Li Lu and Cheng Yuguo when they were in the park with their children before the '7.28' case, and they didn't watch the monitoring on the way back for the time being.

The other split screen is yesterday, Liu Chen and Xun or from the close to the building where the café is located, and the monitoring when they enter the building to leave after dinner, as for the relevant picture when the two go to the hotel to open a room, for the time being, they will be in the back row.

Because when Cheng Yuguo and Li Lu were playing in the park, their whereabouts were not fixed, and the area of the park was large enough that the monitoring could not be completely covered, so the probability of finding the suspect in various key monitoring areas inside and outside the park was relatively small.

So what Xiao Ran focuses on is the surrounding crowd of Liu Chen and Xun or the two, after all, they are on the commercial street, there are almost no dead ends in the monitoring, and the picture quality is high, so it is naturally the object of Xiao Ran's key viewing.

In fact, this choice did not disappoint Xiao Ran.

The surveillance had just been watched for about ten minutes, and when the deceased Liu Chen in the '8.09' case was holding the old man and waiting for the elevator and was about to go upstairs to eat, a figure suddenly walked into the monitoring range in the corridor in front of the elevator.

At the same time, the Eye of Justice throbbed violently.

Xiao Ran immediately paused all the surveillance footage, staring at this tall and thin figure with his eyes.

Because the surveillance video has not been sharpened, and this figure has just walked into the monitoring range with several people, so this person's face is not very clear.

Xiao Ran continued to play the monitoring here.

As the man got closer, he could see that he was wearing a suit, combing his middle, and holding a few books between his arms, slowly approaching the elevator, with his chin tilted up, and his expression was arrogant, like a nobleman walking into a slum.

As this person approached, Xiao Ran also saw his appearance clearly: long face and white face, very light eyebrows, slanted eyes, drooping corners of the mouth, height was very in line with the judgment of technicians, about one meter eight, standing in front of the elevator with a wandering gaze.

As soon as he saw this person's face, Xiao Ran had a sense of déjà vu.

But he stared at this man's face for a while, and still didn't remember where he had seen it, after all, there were too many people to contact in his business, and generally unimportant people didn't pay much attention.

Until Xiao Ran noticed the two books and a notebook between the man's arms.

Although the video is not high-definition, Xiao Ran guessed the corresponding titles from the covers of the two books, "Supreme People's Procuratorate Bulletin" and "Perfume: A Murderer's Story".

"It's him!"

Xiao Ran frowned slightly, muttering surprise and pity.

He had already remembered that this person was the wild expert he met who wanted to help them solve the case when he and his colleague named Mei Peng from the Chengdong Police Station visited Yongqiao Village when he was investigating Zheng Huanju's case a year later.

The content of Xiao Ran's memories gradually became clear.

He remembered that when the man introduced himself at that time, he seemed to have said that his name was Weng Tao, and this person had also shown off to them the four perfect methods of committing crimes.

This man named Weng Tao told them at the time that the same modus operandi could not be used for serial crimes, and that it was necessary to ensure that it was not witnessed when committing crimes, and that it was necessary to wear gloves and shoe covers, and it was best to choose to commit crimes on rainy nights, avoid surveillance, and set the target of the crime as strangers.

Weng Tao summed up the methods they said at that time, how consistent with the modus operandi of the '7.28' and '8.09' cases!

Xiao Ran had basically determined in his heart at this time that this person named Weng Tao should be the murderer of these two cases.

It's just a pity that a person who was innocent at the time has now become a suspect in a serial murder case.

- Maybe I should have talked to him at that time, but the case was urgent at that time, Guo Yilei's life and death were unknown, where did I get the time to talk to him?

"Is it him?

Hearing Xiao Ran's whisper, Zhang Lei immediately poked his head out, and several other colleagues also stood up reflexively, thinking that Xiao Ran had created another miracle.

"Oh, I just saw someone I'd met before, nothing. ”

Xiao Ran said with a smile, after all, the monitoring has not been watched, and the process of identifying the suspect in just a few seconds is too hasty.

Hearing Xiao Ran's words, Zhang Lei and the others all sat back slightly saddened, and continued to stare at the screen to watch the monitoring.

Xiao Ran continued to broadcast the monitoring and looked back......
