In a crime scene investigation, what does the term 'transient evidence' refer to?

The term 'transient evidence' refers specifically to evidence that is temporary in nature and can be easily altered, lost, or destroyed if not collected promptly. In the context of a crime scene investigation, transient evidence can include things like odors, temperatures, impressions, or physical markings that may change or disappear over time due to environmental factors or disturbances at the scene. This is why it is critical for investigators to identify and collect such evidence as quickly as possible to preserve its integrity and ensure it can be accurately analyzed later.

Choosing evidence that is easily recoverable without any time constraints or evidence that requires minimal effort to collect misses the crucial aspect of the temporal nature of transient evidence. Similarly, neglecting this type of evidence or claiming it can be disregarded would undermine its potential value in a criminal investigation. Collecting this evidence promptly is essential for maintaining the integrity of the investigation and supporting legal processes that may follow.
