What is transient evidence?

Transient evidence refers to types of evidence that are temporary in nature and can change or vanish over time. This can include things like odors, marks, and temperatures that may not be present after a short period due to environmental factors or the passage of time. For instance, a freshly made footprint in the mud could disappear if it rains, and a scent might dissipate within a few hours. The significance of transient evidence lies in its fleeting nature, which requires immediate recognition and collection by investigators to preserve it for analysis and use in a case.

The other options do not accurately define transient evidence. Easily collected visible evidence implies permanence and accessibility, which is not the case for transient evidence. Static evidence, which remains unchanged and can be documented, does not capture the essence of transient evidence's impermanence. Finally, the need for a warrant pertains to legal considerations for collecting certain types of evidence, which is distinct from the properties that define transient evidence.
