3. How can investigators determine the existence of crime?
Investigators start by investigating the crime site and interviewing witness. They focus on physical leads and try to set up events chronologically, aiming to realize if there was enough evidence regarding the occurrence of a crime. Finally, they break down the case based on motivation, opportunity, and means used by the possible perpetrator.
4. What is the difference between a detective and a criminal investigator?
In many jurisdictions, the terms “detective” and “criminal investigator” are used interchangeably. Both roles involve solving crimes, but detectives may specifically focus on investigating major crimes like homicides, robberies, and sexual assaults. Criminal investigators, on the other hand, can be involved in any type of criminal case, from minor offenses to complex organized crime operations.
5. How long does a criminal investigation usually take?
This can vary, but it will depend on the complexity of the case. In some instances, the results can be ready in days or weeks, such as when the evidence is overwhelming or when there is a suspect. Other cases might take months or even years to complete, especially when it deals with organized crime, complex financial crimes, or cold cases. The availability of the evidence, the cooperation of the witnesses and the availability of the resources of the law enforcement agency generally influence the timeline.
