What best defines transitory evidence?

• A. Evidence stored in a filing cabinet.
• B. Evidence that can blow or wash away.
• C. Digital data permanently recorded.
• D. Evidence secured with a chain of custody.

Answer: (B)

Transitory evidence is information or physical traces that are temporary and can disappear or change quickly if not captured right away. The key idea is that this type of evidence is not meant to be permanently preserved and can be lost with time or a simple event like wind or water. The option that fits this best describes something that can blow or wash away, highlighting how easily it can be destroyed or altered and thus needs prompt collection. In contrast, evidence kept in a filing cabinet is durable and intended to be preserved, digital data that’s permanently recorded remains, and chain of custody relates to the handling and tracking of evidence rather than its temporary nature. Understanding transitory evidence helps investigators act quickly to document and collect it before it’s gone.
