Missing Persons; Walking searches are most effective. If not found in 6-12 hours, shift search to secluded/natural areas in __ mile(s) radius.

• A. 0.5 mile
• B. 1 mile
• C. 2 miles
• D. 5 miles

Answer: (B)

When searching for a missing person by walking, you focus on the area around the last known point, because most individuals remain nearby in the early hours. If the person isn’t found after about 6–12 hours, expand the search to secluded natural areas within a walkable radius so teams can systematically cover likely paths and shelters still close to the last point. A radius of about 1 mile strikes a practical balance: it’s large enough to include areas a person could reasonably reach on foot, but small enough to allow thorough, methodical coverage by search teams in a timely window. A smaller radius like 0.5 mile risks missing someone who moved a bit farther, while a larger radius such as 2 or 5 miles becomes harder to cover effectively with walking teams, reducing the chance of a rapid find. Terrain can affect speed, but the principle remains to limit the next phase to a manageable, high-probability zone around the last known location.
