What is the purpose of a criminal investigation?

The purpose of a criminal investigation is to find out if someone has committed a crime. In Virginia, criminal investigations are conducted by law enforcement officials, such as police officers, detectives, and prosecutors. The investigation process is used to determine the facts of a case, identify any potential suspects, and gather evidence to support the legal charges. During an investigation, law enforcement officials may interview witnesses, review physical evidence, take photographs and collect other evidence. This evidence is analyzed to determine if a crime was committed and if a suspect can be identified. In addition, investigators may use technological methods, such as DNA analysis, to build a case. Investigators use the evidence collected during an investigation to build a case against a suspect for arrest and prosecution. Once a suspect is charged with a crime, the criminal justice system takes over and the suspect is provided an opportunity for a fair trial. The purpose of a criminal investigation is to ensure that all suspects are held accountable and justice is served. A thorough and professional investigation helps ensure that the innocent are not wrongfully accused and that the guilty are held responsible for their actions.
