At this moment, the Night Apostle once again left this suspense for the crime team, they knew very well that if the Night Apostle was not caught as soon as possible, then I really don't know how many innocent people would be killed.

It can even be said that judging from the current situation, it is more difficult to catch the murderer of the innocent, precisely because of the words of the Apostle of the Night: Do you really think that Sun Hua is the so-called murderer?

That's right, judging from the current situation, there are indeed a lot of clues pointing to Sun Hua, but if you use this to conclude that Sun Hua is the murderer, it is indeed a bit too hasty, which is unreasonable.

What the other party said is not impossible, the person who can guide Wang Sihua to move in the dark, in addition to Wang Sihua's ex-girlfriend Sun Hua, there should be someone else, but the police have not yet investigated clearly.

I believe that Wang Sihua also contains a certain amount of private space in his own life, and everything that happens in this space is absolutely indelible, and Wang Sihua will never tell these things casually.

Then, Wang Sihua's friends or colleagues have never learned about these related cases, so it is understandable, but now if Ziwu and others want to find the real clues, it will take a lot of effort.

Therefore, now Ziwu has issued an order that some people continue to investigate the matter related to Wang Sihua, while Ziwu himself leads another group of people to start carrying out the case of the so-called blade indicated in the envelope.

This time, the two case colleagues launched an investigation, and Ziwu really doubted whether they would be able to carry it down, but no matter what, they must find the traces of the Night Apostle as soon as possible, and no more innocent people can be killed.

As a technician, Wang Jin is mainly responsible for everything about Wang Sihua, including the information in the computer used by Wang Sihua and the chat list and content of the account used by Wang Sihua on the dating tool.

At the moment, Lin Rou stayed at the police station to conduct a second inquest on Wang Sihua's body, Lin Rou always felt that there seemed to be other secrets hidden in Wang Sihua's body, and it was definitely not just as simple as a nail piercing his head.

As for Ziwu and Xiaoli, they now drove to the supermarket with a few policemen, because they found that in the lower right corner of this blade was a name named Lifeng, which is a brand of blades.

According to the police's market research, there is only one place in the city where the Lifeng blade is sold, that is, in the supermarket in the west of the city, and this blade is the latest model, which has just been on the market for a short time, so someone must have bought it there.

Now, they only need to follow this clue to extend the investigation, I believe that it will not be long before the case will be clear, at least who bought the blade, the police can find out, and finally the case should be solved.

After an hour's journey, they managed to come to the so-called supermarket in the west of the city, and made detailed inquiries to the cashier in it, and learned from the cashier's mouth that this blade had just been put on the market recently, and the sales were not very hot.

It is estimated that there are less than ten people who buy it, after all, many people will give preference to the blades they have used, and the reason why these people buy this blade may be because of the advertising slogan used in this blade.

"With a knife in hand, I have it in the world." If you say such a domineering word, anyone who listens to it will have an inexplicable impulse, and those people seem to be touched by this advertising slogan, so they will start to try the new blade.

Ziwu and others don't pay attention to what advertising slogans, they focus on those who buy blades, after all, the murderer or the victim is likely to hide in the blade, and they must speed up themselves.

The cashier was quite cooperative with the police's investigation, and after hearing that the police were going to retrieve the surveillance video, he immediately led the police to the monitoring room and helped the police open the surveillance video of all buyers.

"A few police officers, you just watch here first, if there is anything to call me, I am alone on duty in the supermarket today, and the guy in the monitoring room has also asked for leave, and I have to go to the front to take care of business." With that, the cashier turned and left.

"Boss, the guy in the monitoring room has taken a leave of absence, is this in order? According to my understanding, doesn't the monitoring room usually have two people alternately? Xiao Li had a strong question about the words in the cashier's mouth at this moment.

"I look at you, don't be suspicious here, they, I guess it's because the scope of business is not particularly large, so a monitor can be busy, but at this time it doesn't look very reasonable, but it's harmless." Ziwu continued to watch the surveillance.

In the surveillance, Ziwu can clearly see that two people who have made an appointment to appear in front of the cashier counter of the supermarket, and the checkout information that appeared on the cashier at that time is the blade of this Lifeng brand, and these two people are temporarily included in the name of the investigation.

In addition, Ziwu also saw a young woman about twenty-four or five years old and a child estimated to be thirteen years old, both of whom were also checking out a box of Lifeng brand blades at the checkout counter of the supermarket.

This is all the people who can find the blade at present, there are four of them, they are not the same age, the gender is not the same, the height and body shape are also different, but the only thing that can connect them together is the blade of the Lifeng brand.

At present, Ziwu of the crime team collected the face information of these people, and then brought it back to the police station for Wang Jin to deal with.

Ziwu firmly believes that there must be a goal to be guided by the Apostle of the Night among these people, and this goal needs to be discovered by Ziwu little by little.

Driving to the home of the two men who had gone to buy blades together, Ziwu knocked lightly on the door in front of him, and about a minute later, there was a rush of footsteps inside the door, as if he was running fast.

And after the footsteps gradually approached, the door in front of Ziwu was slowly opened: "Hello, is there anything I can help you with?" ”

Looking at the two plainclothes policemen in front of him who were not wearing police uniforms, this person really couldn't figure out what they had to do with him, but in his mind, the face of the salesman selling insurance had already appeared in his mind.
