What does a successful investigation involve?

A successful investigation typically culminates in closing the case, which often involves making an arrest when there is sufficient evidence to support charges against a suspect. The primary goal of an investigation is to resolve a criminal case by establishing the facts surrounding the incident, which generally includes not only gathering evidence but also identifying and apprehending suspects based on that evidence.

While discovering evidence, gathering witness testimonies, and conducting field surveys are all crucial elements of the investigation process, they serve as steps toward the ultimate goal of closing the case. An investigation that leads to an arrest signifies that law enforcement has effectively used the gathered information to address the crime, ensuring accountability for the actions that have taken place. Therefore, the essence of a successful investigation can be viewed through its end result, which is to ensure justice is served, often marked by an arrest when warranted.
