Which description defines a mobile witness?

• A. A witness who moves through space and time
• B. A witness who remains stationary
• C. A witness who travels through space and time
• D. A witness who is an expert observer

Answer: (C)

Mobility in a witness means they are not tied to a single location or moment. A mobile witness is someone who travels through space and time, meaning they may be encountered at different places and at different times as events unfold. This mobility affects how investigators locate and interview them, often requiring flexible interview methods such as remote testimony or multiple sessions. In contrast, a witness who remains stationary is not mobile, and an expert observer speaks to the witness’s expertise rather than their location or timing. So the description that best captures the idea is someone who travels through space and time, reflecting movement across locations and moments.
