What must an investigator be able to recognize when dealing with evidence?

Recognizing objects that are out of place is a critical skill for an investigator because such discrepancies can provide significant clues about the events that took place at a scene. Items that are not typically found in a setting can indicate that something unusual has occurred, possibly related to the fire or incident being investigated. Identifying these objects helps in constructing a timeline and understanding the actions of individuals involved before, during, and after the incident.

In a fire investigation context, out-of-place items could include items that are either in locations they should not be, such as personal belongings in a restricted area, or they may be items that do not belong to the resident or establishment. This recognition can prompt further inquiry into their significance and origin, which is essential for gathering evidence and supporting investigative conclusions.

While understanding tampering, removed items, and familiar locations can also play a role in an investigation, the immediate recognition of what appears to be out of place often serves as the first step in uncovering critical leads and evidence related to the case.
