In which stage of crime scene investigation is a detailed search conducted?

A detailed search is conducted during the stage known as the detailed examination. At this point in the investigation, investigators systematically comb through the crime scene to uncover and collect evidence. This phase allows for meticulous observation and documentation of the scene, ensuring that no evidence is overlooked. Investigators often employ various methods such as grid, spiral, or zone searches to cover the area thoroughly.

In contrast, the preliminary survey involves an initial assessment of the scene, where law enforcement officers establish the context and safety of the area, but not a comprehensive examination. While the final survey is designed to ensure that everything has been documented and collected properly before leaving the scene, it does not focus on the in-depth search aspect. The initiating scene approach is more about how to enter and assess the scene safely rather than performing the detailed examination needed to gather evidence.
