Observation & ReportsQuestion 141 of 200

Arriving first at the scene of a likely crime, the guard's primary preservation duty is to:

a.Begin a full forensic search of the area

b.Render any needed first aid and call 911/employer, then secure the perimeter, prevent unauthorized entry, avoid touching or moving evidence except where necessary for safety or first aid, identify and detain available witnesses, and brief responding officers — minimizing contamination is paramount

c.Clean up the scene to restore appearance

d.Interview the suspect at length before police arrive

Explanation

First-responder duties at a likely crime scene, in order: (1) ensure safety — your own, then others, rendering first aid if trained; (2) call 911 and notify supervisor/dispatch; (3) secure the perimeter with whatever materials are available; (4) prevent entry by anyone unauthorized — including coworkers and curious bystanders; (5) avoid touching or moving anything unless required for life safety; (6) note witnesses and ask them to remain; (7) brief arriving officers on what you saw, did, and where. Forensic search (a) is the detectives' role. Cleaning (c) destroys evidence. Suspect interviews (d) are best left to police given Miranda and §841 considerations.
