Artificial intelligence will allow the Public Ministry to identify criminal networks, looking for links between potential suspects. In the early days it was used in crimes against property, but work has already been done to adapt the system to cases of murder and drug trafficking.
The Chilean Prosecutor’s Office has already begun implementing an artificial intelligence system designed to suggest criminal networks and thereby facilitate the identification of potential suspects in their investigations.
As announced by the Public Minister, this system has been disseminated over two years by the Fondef project by experts from the University of Chile, Los Andes and Bío Bío, with the aim of optimizing research processes. Thus, he will begin to use the offices of the regional prosecutor of Maule, Coquimbo and Metropolitana Centro Norte.
A mathematical model has been created for crimes against property that is fed by various databases, such as the Support System for Prosecutors (SAF), to project in seconds the identities of gang members potentially associated with the crime. He will soon be tried, suited to murders and drug cases.
The mechanism, they say, consists of identifying a person as the initial node, from which connections emerge with third parties with whom they have shared at least one previous crime. In this way a map of the criminal network is generated.
In the event that there is no such initial person, the system compares the facts, jurisdiction and regulations applied, among other variables.
Developed by Fondef, the system will begin to be used for cases of crimes against property in the Criminal Analysis units of the Maule, Coquimbo and Metropolitan North Central regional prosecutors, to progress to other more complex crimes in the coming months.
“The goal is to help prosecutors quickly determine, in the second case, what people might do in a criminal act to be ascribed to a group. Whether we have a suspect or not, we hope that it will be a great help to reduce the crimes of unknown criminals”, explained the National Prosecutor Angelo Valencia, during the official presentation of the system.
The idea that developed this artificial intelligence, by the Criminal Analysis and Focal Coordination Unit of the National Prosecutor’s Office (SACFI) and Researcher In the Institute of Complex Systems Engineering of the University of Chile, Richard Weber, together with Carla Vairetti from the University of Los Andes and Fredy Troncoso from the University of Bío Bío.
Now, the same team is making progress on specific mathematical models for homicides and drugs, integrating new elements of behavior and knowledge of specific skills needed to complete a crime, among other elements.
According to Weber, “with this system, each prosecutor and his team will no longer have to analyze many folders to find potential links, while the machine filters and proposes a few. The benefit is to reduce the volume and complexity of the search, making it smarter. With this algorithm also to hypotheses will contribute to confirm the research.
The team has already conducted several trials in burglary cases with success rates. As an example, one of them worked on a recent event in which 12 known people were involved. The account of the identity of only two was given, so that they could trace and propose the identities of seven new men, all of whom were ultimately convicted.
