What should investigators do if they have already been to the neighborhood?

When investigators have already been to the neighborhood, conducting the investigation again can be a prudent choice under certain circumstances. Re-evaluating the area can lead to the discovery of new evidence or insights that may have been overlooked during the initial visit. Factors such as changes in the environment, new residents, or the passing of time can yield different perspectives or additional information that could aid the investigation.

The nature of investigations often requires a thorough understanding of the surroundings, and revisiting can facilitate deeper inquiries. As more people become aware of the investigation, informal conversations with new neighbors or those who were initially unwilling to talk may reveal valuable information.

This approach emphasizes the importance of diligence and the possibility that further visits can enhance the integrity and efficacy of the investigative process.
