"What about the trap?" Huo Yan listened to Ning Shuyi's explanation and thought thoughtfully.

"According to the geographical portrait of criminals in criminal psychology, one of the theories divides criminals into four types according to the pattern of criminals looking for victims - hunting, poaching, baiting, and trapping.

What we've encountered this time is very similar to the previous situation, and I think it's very likely that it's a trap type here." Ning Shuyi explained.

"I don't know the specific classification criteria you're talking about, but it sounds like this 'baiting' is quite similar to the two murders we encountered." Huo Yan felt that in front of Ning Shuyi, what he lacked in theory was really not a little bit, so he was particularly pious in his discussion.

"It does sound like it at first glance, but I was actually a little hesitant just now." Ning Shuyi nodded, "Compared with the bait type of crime and the trap type, the biggest difference is that there is no specific standard for the type of victim selection, and the location is relatively random, as long as someone takes the bait, then the crime will be committed anytime and anywhere."

On the other hand, the trap-setting offender chooses the location of the crime in advance, uses a certain method to lure or abduct a specific type of victim to the scene, and then kills him.

Whether it is the location of Yan Dayuan's accident in the past, or the location of the female victim's accident whose identity is not yet clear this time, they all have valuable traces such as the surrounding area is relatively quiet and not easy to be disturbed, there is no monitoring equipment, and it is not easy to leave footprints at the scene.

This commonality makes me think that although the two murders did not occur in the same place, the scene of the crime was definitely not random, but was carefully selected by the suspects."

"But Yan Dayuan and the real female deceased, whether it is in terms of age, gender, or even the family background and living environment that we guess, I am afraid that they will not find any intersection." Huo Yan felt that what Ning Shuyi said was very reasonable, but there were some doubts that had not yet been solved.

"yes, at first glance, it really seems that they are two people who are completely unrelated, so I can only subjectively prefer to set a trap type, and I can't really be sure of my own speculation.

Now it depends on who the deceased woman is, and once her identity is confirmed, maybe we will be able to find out what kind of intersection exists between them." Ning Shuyi sighed, "Regardless of whether these two people intersect or not, being bitten alive by a fierce beast is quite a cruel way to die!"

I think this method of death is probably more or less related to the lives of these two people, and maybe although there is a big age gap between these two people, there is some kind of commonality, which has become the cause of the tragic death of the two of them."

Huo Yan frowned and thought for a while, and asked Ning Shuyi, "Then if your previous speculations can be established, this is an organized series of murders carried out by a trap-type criminal.

Now that there are two victims, will there be a third?"

"It's entirely possible, there's no way to generalize.

After all, we still don't know why the other party wants to target the two of them, and if the revenge is avenged, maybe there won't be another target.

But if the killer's target is not against these two people themselves, but at some underlying resentment, then as long as they can find something in common with these two people, there is still a risk of becoming a target."

"Then you mentioned the cooling-off period earlier, how long is the cooling-off period?"

"It's hard to say." Ning Shuyi shook his head, "It can be long or short, a few days, a month, a few months, or even a few years of incubation.

There was a gap of more than a month between these two times, and if there was a third victim, the cooling-off period between the two times would not necessarily be more than a month.

Because it is the first time to commit a crime, unless the other party is a habitual veteran, he will inevitably tremble.

Maybe in the intervening more than a month, the suspect has been secretly observing his own achievements through various channels to determine that the limelight has been

In the past, there was no risk, so I was down-to-earth and more bold, and this is the second crime now.

If there is still no movement this time, so that the suspect feels encouraged again, it is very likely that the cooling-off period between the next crime and the next crime will be greatly shortened."

Huo Yan thought about it carefully, "Then according to your statement, should we be more high-profile or low-key when we investigate the case of this female deceased this time?

I kept a low profile for fear that the other party would think that we had not done anything and were in a hurry to commit the next crime.

It's high-profile, and I'm afraid of startling the snake."

"If you're afraid of startling the snake, you know that there are snakes hidden in the grass." Ning Shuyi didn't bother too much about this, "Our current situation is that we are not sure where the snake is, let alone who the snake is going to bite.

Rather than being low-key without meaning, in my opinion, it's better to be high-profile.

Usually, the perpetrators of a series of crimes will lurk in the shadows after committing a crime, and learn about the outside information through TV media or the Internet to determine whether they are at risk of exposure.

We can let this suspect hiding in the shadows know that this case is not unsolved, but we will not let the other party feel that he has been exposed to the light and must go away.

To be honest, this scale and proportion are really not particularly easy to grasp, and I have to talk to Dong Brigade to see what he thinks about this matter when I go back."

Huo Yan nodded: "Okay, I'll talk to Team Dong tomorrow morning."

This night, the two of them each found a duty room to make do with the night, because they saved time on the road, and the next morning Huo Yan also called Shangning Shuyi to go out for a morning run, had breakfast, and knocked on the door as soon as the Dong brigade arrived at the office.

After listening to them talk about the case at hand, Dong Weifeng also felt that Ning Shuyi's judgment was very reliable.

"I think it's doable." After considering the pros and cons, he finally nodded, "The two victims both happened at the boundary of the city, and they were both selected in the kind of surrounding areas that are relatively desolate and not covered by surveillance, which shows that the suspect is still familiar with the environment of the city."

Generally speaking, suspects in this series of cases will not easily choose to act recklessly in an environment that they are not familiar with, so as long as the other party does not feel that he is locked up, but the police have noticed the extent of this case, I think the other party will not easily leave their familiar environment and flee in panic."
