KeyCrime’s holistic approach to extracting investigative value from crime data follows a process that is the fruit of decades of investigative experience on the part of its founder, Mario Venturi and his staff. We start with guided data collection with specific data elements for each type of crime. This guarantees a solid (and complete) base for investigators so that delia®’s advanced search and data visualization methods can best support them while they perform crime data analysis. The complete and accurate data also allows the adaptive algorithms in delia®’s crime-linking engine to identify best matches between new criminal events and existing events, providing useful insights to investigators about how events might be linked. By analyzing locations and criminal habits, KeyCrime helps investigators predict likely future locations and potential times for the next crimes in the series. This allows police departments to better plan their activities to maximize the effect of their efforts in crime prevention and repression.
