crime profiler in the dark

TMX City Baihu Police Station

Early in the morning, Bai Haolin couldn't wait to come to the police station - the support department has established a more detailed crime database, which archives all cases in the past 20 years, and can search for the type of case and the information of the victim through simple words and sentences , crime characteristics, etc., is a very convenient system.

Now that it has been confirmed that the other party is a serial killer and Hong Si is not the only victim, it is very likely that some of his criminal patterns have been recorded in the police station's files, but they have not been discovered yet.

Bai Haolin entered the characteristics of the criminal in the special search terms of the police station: male, 40 to [-] years old, murdered more than five people, had the habit of throwing corpses, and the search period was within five years.

The search results showed that there were not many cases, only seven cases, and all of them had been solved. Two of them belonged to murders by gang members, three were murders by robbery, and the other two were revenge murders, which did not match Bai Haolin's analysis.

According to the usual practice of the police, the media must pay close attention to such a big case, so they will definitely try their best to close the case, so the result may be distorted.

Bai Haolin called up the detailed information of these cases, trying to find evidence related to the "mysterious person", but unfortunately, the facts of these cases were simple, and the crimes of murder by gang members and robbery and murder were exactly the same. He stabbed someone with a knife and ran away until he was caught; the two revenge homicides injured the target of revenge and his family together, which did not match the characteristics of the "mysterious person" and they all passed.

Bai Haolin rubbed his temples, thinking again.

Could it be that the body of his victim has never been found?Since he has set the rules for himself, it means that he has explored a set of strict methods in many practices, maybe what he did was not noticed by the police at all, and his victim should not be in the death file, but Is it in the missing archive? !

Bai Haolin re-selected to search for missing persons within five years.

In just three seconds, a series of lists appeared on the screen, with a total of 475 people in this list.

Of course, not all of these people were the work of "mysterious people", and he had to exclude some of them.

First of all, according to his analysis of the "mysterious person" appearing in the parking lot, he should be preparing to attack his target, then from the usual psychological analysis of serial killers, his murder target should be specific from the beginning, then first Women and children should be excluded.

Now only 126 people remain on the roster.

The second is the motive. When the police solve a case, they first start with the motive of committing the crime, and disappearance is no exception.For disappearances, the police will first assume that they are lost. If there are no signs related to kidnapping, most of them will just let it go. disappeared, so such cases of disappearance should be excluded.

Another 47 people were removed from the list, leaving 79 people.

Looking at the long list, Bai Haolin wanted to exclude some more, but he didn't know much about "mysterious people", so he had no way to reduce the number of people on the list.

Just when his thoughts were bogged down, a mark with ※ at the back of the list caught his attention.

There is a note on ※ at the bottom: there is a criminal record.

Criminal record?

After screening, Bai Haolin found that 79 of the 23 people were of this type. Of course, he didn't think it was just a coincidence that so many inmates disappeared. Looking at the time of their disappearance, 90% of them were at night. Obvious common features, but combined with the fact that the time of the "mysterious person" was also at night, this is not just a coincidence!
