"What about the trap?" Huo Yan was thoughtful as he listened to Ning Shuyi's explanation.
"Based on the geographical profiling of criminals in criminal psychology, one theory divides criminals into four types based on their patterns of finding victims - hunting type, poaching type, baiting type, and trap setting type. .
What we encountered this time is very similar to the previous situation. I think it is very likely that it is a trap type. " Ning Shuyi explained.
"I don't know the specific classification criteria you mentioned, but it sounds like this 'baiting type' is quite similar to the two murder cases we encountered." Huo Yan felt that he was in front of Ning Shuyi , the lack of theory is really not even a little bit, so it seems particularly pious to discuss it.
"It does sound similar at first glance. I was actually a little hesitant just now." Ning Shuyi nodded, "Compared with bait criminals and trap-setting criminals, the biggest difference lies in the choice of victim type. There is no specific standard, and the location is relatively random. As long as someone takes the bait, they can commit crimes anytime and anywhere.
Trap-setting criminals, on the other hand, have chosen their preferred crime location in advance, used a certain method to lure or abduct specific types of victims to the scene, and then killed them.
Whether it is the place where Yan Dayuan's accident happened before or the place where the unknown female victim's accident happened this time, the surroundings are relatively quiet and not easily disturbed. There are no surveillance equipment, and it is not easy to leave valuable traces such as footprints at the scene. clue.
This commonality makes me think that although the two murders did not occur in the same place, the crime scenes were definitely not randomly generated, but were carefully selected and finally determined by the suspects. "
"But Yan Dayuan and Zhen were the dead women. No matter in terms of age, gender, or even our guessed family background and living environment, I'm afraid we can't find any intersection." Huo Yan thinks Ning Shuyi's words make sense. , but there are still some doubts that have not yet been solved.
"Yes, at first glance, they are really two completely unrelated people, so I can only subjectively prefer to set up traps, and I can't really confirm my speculation.
Now we have to see who the deceased female is. After confirming her identity, maybe we will be able to find out what kind of intersection there is between them. Ning Shuyi sighed, "No matter whether these two people have crossed paths or not, being bitten alive by a beast is a very cruel way to die!"
I feel that this way of death may be more or less involved in the lives of these two people. Maybe even though there is a big age gap between these two people, there is something in common that leads to their tragic deaths. s reason. "
Huo Yan frowned and thought for a while, then asked Ning Shuyi: "Then if your previous speculations are true, this is an organized series of murders carried out by a trap criminal.
Now that there are two victims, will there be a third one? "
"This is entirely possible, and there is no way to generalize.
After all, we still don’t know why the other party targeted the two of them. If the big revenge is avenged, maybe there will be no next target.
But if the murderer's target is not the two people themselves, but some underlying resentment, then as long as they can find someone who has something in common with the 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 usually?"
"It's hard to say." Ning Shuyi shook his head, "It could be long or short, it could be a few days, a month, a few months, or even a few years.
There was more than a month between the two times. If there was a third victim, the cooling-off period between the two times might not be more than a month.
Because it is the first time to commit a crime, unless the other party is a veteran criminal, he will definitely be trembling with fear.
Perhaps in the intervening period of more than a month, the criminal suspect has been secretly observing his results through various channels, and is sure that the limelight has been
After that, there was no risk, so I became more at ease and became bolder, which is why I committed the second crime now.
So if there is still no movement this time and the suspect feels inspired again, the cooling-off period between committing the next crime is likely to be significantly shortened. "
Huo Yan thought about it carefully: "According to what you said, when we investigate the case of the deceased woman this time, should we be more high-profile or low-key?
We keep a low profile because we are afraid that the other party will think that we have not done anything and are in a hurry to commit the next crime.
Being high-profile and afraid of alerting others. "
"The premise of fearing to scare a snake is that you know there is a snake hidden in this piece of grass." Ning Shuyi is not too entangled in this, "Our current situation is that we are not sure where the snake is at all, let alone what the snake is preparing to do. Who is going to bite.
Rather than being meaninglessly low-key, in my opinion it is better to be high-profile.
Usually, perpetrators of serial crimes will lurk in the dark after committing a crime, and use television media or the Internet to learn about outside information and determine whether they are at risk of exposure.
We can let the suspect hiding in the dark know that the case is not settled, but we will not make the other party feel that he has been exposed and must fly away.
To be honest, the scale and propriety are not particularly easy to grasp. I will have to talk to Team Dong later to see what he thinks about this matter. "
Huo Yan nodded: "Okay, let's talk to Captain Dong tomorrow morning."
That night, the two of them found a duty room and stayed the night together. Because it saved travel time, Huo Yan asked Shang Ning Shuyi to go out for a morning jog the next morning, had breakfast, and went to the office in Dong Brigade. I immediately went over and knocked on the door.
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 feasible." After considering the pros and cons, he finally nodded, "Both of the two victims occurred in the city limits, and they were both chosen in areas that were relatively desolate and not covered by surveillance. This shows that the suspect is relatively familiar with the city's environment.
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 they are being targeted, and it is only to the extent that the police have noticed the case, I think the other party Nor will he leave his familiar environment easily and flee in panic. "
