Is it fast? How fast does it have to be so that the surveillance does not capture the slightest trace? Is this speculation scientific? Many police officers couldn't help but think in their hearts.

The man from the task force obviously guessed the inner thoughts of these policemen, and patiently explained: "If any of you have ever handled an unsolved case or a strange case, you must have felt this way, maybe at first you felt incredible about your speculation, but when the secret was revealed, you all took it for granted. ”

The police officers present were experienced criminal investigation masters, and naturally they had all experienced this situation, and they nodded one after another, but they were a little timid because they had not been able to solve the case of the night wolf for a long time.

"Now this is the case, and the murderer can no longer be found by common sense, so we can only start with a non-common sense perspective to see if more discoveries can be made. ”

At this time, a police officer said loudly: "But even if we know that it was a person who took the victim away at a very fast speed, we still can't find the target." ”

"Bring up the nearby surveillance, and compare all the people who appeared around during that time one by one to see if there are any duplicates. The task force man immediately spoke, "He's sure to follow his target before he makes a move." ”

"We've looked for this, but there isn't a single duplicate in all the surrounding videos, the victim died in a different area, and the crowd around him is completely different. At this time, the other officer shook his head with a wry smile.

The man's pupils shrank sharply when he heard this, and his voice became heavier and heavier: "Then call everyone here and interrogate them one by one!"

The previous police were not qualified to conduct such a large-scale screening, but the task force sent from above had a high level of authority, and they had the power to call everyone to the police station for questioning.

So a large-scale comparison operation began, comparing the faces captured in the surveillance, each one was taken to the identity information database for comparison, and then found out their addresses and contact information, and began to contact one by one.

This is a huge undertaking that requires the cooperation of the Directorate General and the Sub-Bureaus to accomplish it.

"Hey, why is this stinky boy here?"

At this moment, the police officer who had explained before suddenly whispered something in confusion while looking through a surveillance video.

This sentence happened to be heard by the men and women of the task force not far away, and the woman looked at the officer and asked, "Officer Lin, do you have any special findings?"

"Oh, it's nothing Commissioner Xu, I just didn't expect to see someone I knew in the surveillance, and I was a little surprised for a while. Officer Lin immediately reacted and replied.

"Acquaintance?", the male commissioner also walked over with some curiosity and asked.

Officer Lin saw that he couldn't get away, so he paused the video playback, and then pointed to one of the young men and said: "It's him, this young man's name is Jiang Sheng, he caused trouble everywhere in society when he was a minor, so he was detained several times, so I still have a little impression of him." ”

"Oh?" Commissioner Xu suddenly seemed to think of something when he heard this, and immediately said to the surrounding police officers, "Screen out those who have criminal records among these people and focus on interrogation!"

"Understood!"

After seeing everyone's answers, the male commissioner continued: "Does this Jiang Sheng have a criminal record?"

"Well, when I was a child, I was ignorant and mixed with society, and I was detained several times. His parents died in a car accident and he had a vegetative sister lying in the hospital, so he came out early to make money. Officer Lin said without forgetting to add, "A very good child." ”

"What has he been doing lately, do you know?" Commissioner Xu continued.

Officer Lin was asked, and after a long while, he said, "Jiang Sheng later found a job as a delivery boy with my help, and then until now, we haven't been in touch for a long time." ”

"That means, you don't know what he means, do you?" asked the male commissioner again.

Officer Lin suddenly nodded with an ugly face and said, "Commissioner Shen, that's right, but Jiang Sheng is a very good-natured child, he has silently supported his sister's medical expenses for more than ten years, and there may be him in a fight, but he will never do this kind of rape and murder of women!"

"Oh, it's a good boy, but people are the most difficult to see, and as a veteran of criminal investigation, you should know it very well. Commissioner Shen nodded lightly and said, "Maybe it's because of the pressure that he has to choose to release in this way." ”

"But ......," Officer Lin wanted to say something.

Commissioner Xu on the side said softly: "Officer Lin, you should stay sober in front of the case, if this kid really doesn't have any problems, we will ask a few words and let him go back, you don't have to be so nervous." ”

"That kid hates the police department, hey, okay, I'll contact him. Officer Lin also knew that Jiang Sheng would not be able to escape a summons no matter what, so he could only sigh helplessly, and then took out his mobile phone and began to look through the address book.

"Ding~Jingle Bell~"

Jiang Sheng, who was driving, casually clicked on the answer button of the Bluetooth headset, and then said loudly: "Hey, which one?"

"Oh, Uncle Quan. ”

Officer Lin's full name is Lin Zhengquan, and Jiang Sheng is used to calling him Uncle Quan.

"I haven't been in touch for a long time, what's the matter? Oh, what? I've been haunted at a crime scene? Okay, I'm driving an online ride-hailing, and I'll go to your side when I pick up this guest." ”

Hung up the phone, Jiang Sheng breathed a sigh of relief, just now he was thinking about when the night wolf would be caught, but he didn't expect the police station to call him.

When he was a child, he really didn't like the police station, after all, he had been detained so many times, but now he is also an adult, and he is not afraid of crooked shadows, and it is not a big deal to go to the police station for questioning.

What's more, he is not the only one who goes, Uncle Lin has already told him that all the people who have appeared at the scene of the crime have to be questioned, and as a good citizen, he must cooperate with the police.

After completing the order as fast as possible, Jiang Sheng ended taking the order, and then drove to the General Bureau.

To be honest, Jiang Sheng has not yet been to the General Bureau, he has only been hanging around in the sub-bureau before, how can he have the qualifications to be caught in the General Bureau? Even if he has this qualification, he has been well hidden by Jiang Sheng.

As soon as he arrived at the gate of the General Bureau, Jiang Sheng was led by Lin Zhengquan into a normal inquiry room, and in the inquiry room, he saw the pair of men and women in the task force.

After Lin Zhengquan brought Jiang Sheng here, he made a brief gesture and left.

For a moment the door was closed, and only three people remained.

"Hello, you are Mr. Jiang Shengjiang, right?" At this time, the female Commissioner Xu stood up and said, "I am Xu Li, the special commissioner of the National Security Bureau, and this is Shen Qinlin, the two of us just have a few questions to ask you, don't be too nervous." ”

Jiang Sheng did it very naturally, and said lightly in his seat: "You ask." ”

Seeing Jiang Sheng's appearance, a trace of surprise flashed in Xu Li's eyes, generally speaking, when a normal person is involved in a murder case and invited for questioning, he will be more or less nervous, but Jiang Sheng's performance is very normal, his body is naturally relaxed, and he can't see any tension at all.

But soon Xu Li adjusted her state and asked aloud: "What were you doing on Jianchuan Road at noon yesterday?"

"Jianchuan Road?" Jiang Sheng was stunned for a moment when he heard this, and then reacted, didn't yesterday noon happen to be the day when he met with Liu Xin's woman on the battlefield of time? And Jianchuan Road is where the two of them fight!
