Physical evidence can help answer which of the following questions?

Physical evidence plays a crucial role in the criminal investigation process as it provides tangible and objective information that can support or refute aspects of a case. When considering the specific question of "What occurred during the crime," physical evidence can offer insights into the actions that took place, the sequence of events, and the dynamics of the incident.

For instance, items such as fingerprints, blood spatter, weapons, and other trace evidence can reconstruct the scenario of the crime, indicating how the crime was committed, who was involved, and potentially the motive behind it. By analyzing this evidence, investigators can piece together a clearer picture of the events that unfolded, aiding in understanding not only what happened but also the context of the crime.

In contrast, the other questions focus more on procedural or contextual aspects of the investigation, which do not directly pertain to the physical evidence itself. For example, identifying a witness or determining the reporting time involves different facets of the case that are not necessarily gleaned from physical evidence. These aspects are more about procedural documentation and witness accounts rather than the physical manifestations of the crime scene. The duration of the investigation is also related to operational aspects rather than the specifics of what transpired at the crime scene. Thus, physical evidence is most relevant
