Which of the following is NOT part of the investigative process?

The choice of a press conference as not being part of the investigative process is correct because a press conference typically serves to communicate findings or statements to the public and the media, rather than to gather information or evidence. Investigative processes focus on collecting data and information through interpersonal interviews, document examination, and site visits.

Interviews with witnesses allow investigators to gather firsthand accounts and insights about a particular situation, thereby enriching the evidence pool. Gathering relevant documents is critical in establishing a factual basis for the investigation, as these documents often provide key information or context. Site visits typically involve going to the location in question to observe conditions or gather evidence in a practical, real-world setting.

In contrast, a press conference is more about dissemination rather than investigation. It can lead to publicly sharing conclusions or soliciting further information from the public, but it is not an investigative action by nature. Thus, it stands apart from the essential functions that drive the investigative process itself.
