CH 16

Su Hui stood up, and he leisurely introduced: "This is just a simple schematic diagram, time is limited, I didn't draw it in a standard way, it's merely a pretext meant to introduce the theory to everyone. The method I used today is actually not one that everyone understands. It is a branch of the criminal psychological profile, which is called Geographic Profiling, that is, the criminal geography profile. Its principle is to link the perpetrator and the victim with data such as the encounter location, attack location, murder location, and body disposal location to create the criminal psychological profile, and deduce the criminal's residence, the location of the dismemberment, the place of work, or the possible stopover."

Su Hui continued to say: "Actually, this theory just sounds advanced, and there were some sayings among many old detectives in the past, for example 'abandon it far, bury it close', 'head far, body close', 'a little near but far away',  'not close, not far, not repeating'. In fact, these are the basic principles of criminal geographic profiling, but what I deduce now is more systematic."

Then Su Hui turned around to face the crowd and explained in detail: "If there is no crime location, there will be no crime. The choice of location by criminals is not *random, we need to look for the rules, and there are some basic theories, which everyone may also understand. For example, the Circle Hypothesis Theory, that is, the circle of crime: the distance of a straight line connecting the two most geographically distant cases in a series of homicide cases is the diameter, and the focus of the line is the center of the circle, forming a circle at a time.”

Su Hui's voice was a little low, and he talked eloquently, looking like a teacher who was teaching students, but now, all the criminal policemen who had worked in the Major Crimes Unit for several years were in front of him.

TN:

Anyone else thinks this Geographical Profiling is insane? I checked on some of the concepts and let me say, it made me want to drop everything and start studying criminology. Coz how do you find out a person's entire life using basic things like locations one has visited? It's scary and intriguing. This is taking doxxing to a whole other level.
