Open Dock Door and Fresh Footprints at a Distribution Center
At 2:10 a.m. on a cold, rainy night, you are on foot patrol at a 400,000-square-foot distribution center. At dock door 7 you find the overhead door open about 18 inches. The latch is bent outward, the concrete floor is wet, and fresh muddy boot prints lead inside toward the pallet racking. No inbound trucks are on the manifest until 5:00 a.m. You hear metal scraping and a muffled bang from inside near aisle 14. Your radio has a dead zone near the docks, but your cell phone shows two bars. You are alone, unarmed except for a flashlight and radio. The nearest police station is seven minutes away; your supervisor is offsite.
1. What immediate actions should you take, and what should you avoid?
Read the worked answer
Treat the open door and fresh prints as a possible burglary in progress. Do not enter alone through the breached door. Move away from the opening, stay behind cover, and call 911 from a position where you can watch the door. Give the dispatcher the address, dock number, description of the door, sounds, and your location. Then call your supervisor and the site operations contact. If the site has an interior camera or alarm system, ask someone remote to check aisle 14 while you remain outside.
Avoid touching the bent latch, the door handle, or the boot prints. Do not shout into the building in a way that gives away your exact position or provokes a confrontation. Do not attempt a solo search of a 400,000-square-foot warehouse. If a person exits, observe from a safe distance and report direction of travel and clothing; do not chase into the dark. If the person approaches you, withdraw to a secure area and keep police updated. Your role is to observe, contain, and report-not to clear the building alone.
2. What observations should go into your report, and what should be left out?
Read the worked answer
Record objective, time-stamped facts: your patrol route, weather, time you saw the door, exact door number, how far it was open, the direction of the bent latch, the print pattern and direction, the sounds you heard and when, the aisle number, and every notification you made. Note whether lights were on, whether alarms sounded, camera coverage, and the names of people you called. Include what you personally saw and heard, and clearly label secondhand information as secondhand.
Leave out conclusions you cannot prove-'the building was burglarized,' 'the suspect was a former employee,' or 'nothing was taken.' Those belong in a separate investigative summary, if at all. Do not write that you 'secured the building' if you only watched one door. Do not include speculation about who is responsible or irrelevant personal opinions. Use neutral language and exact times. If you did not see a person, say so; do not describe a 'suspect' as if you did.
3. How should you preserve evidence and maintain chain of custody until investigators arrive?
Read the worked answer
Protect the area without disturbing it. Cordon off the dock and the interior path if it can be done safely, and post yourself where you can keep people out. Do not walk through the muddy prints; use a different route or stay outside. If something must be moved for safety, photograph it first, note who moved it and why, and keep it secured. Do not pick up tools, gloves, or paperwork unless there is an immediate hazard.
Start a chain-of-custody log if you take possession of anything: item description, location found, date and time, who collected it, and every transfer. In most cases, the guard should not collect evidence; police or a trained investigator should. Give investigators a clean timeline, camera locations, and access-control records. Preserve your notes and do not rewrite them later. If you review video, record the time range and export method, and do not edit the original.
