The Backpack in the Bushes
At 0720 hours a homeowner flags you down on a walking trail. In the bushes beside the path she found a towel wrapped around a loaded pistol and, next to it, a smartphone inside a plastic bag. Her doorbell camera shows a male on a bicycle ride up at 0630, throw the bundle into the bushes, and ride away. The pistol is a Glock 19 with a magazine inserted and a round in the chamber; the serial number is intact. You are the first officer on scene. Your shift ends at 0800, the evidence technician does not start until 0900, and the phone rings twice while you are standing there. The homeowner wants to go to work.
1. Set out the order of operations at the scene, including what you do before you touch the pistol.

Safety, then documentation, then collection.
- Secure the scene: tape or cones on the path, homeowner's contact information, and confirm nobody has handled the items beyond what she describes.
- Photograph before moving anything: overall, mid-range, and close-up with a scale; capture the towel's folds, the pistol's orientation and exact position relative to the path, and the phone's position in the bag.
- Preserve the doorbell video now - it is the only evidence tying a person to the items. Ask the homeowner to save and share the clip immediately, get her written consent to copy it, and note the camera's clock setting so timestamps can be corrected.
- Render the pistol safe: muzzle in a safe direction, finger off the trigger, magazine out, chambered round ejected and recovered as its own item - that round may carry the only identifiable marks. Do not function-test beyond what is needed, and do not test-fire.
- Record the serial number and description before packaging, and note the magazine capacity and round count.
2. You must transfer everything to the 0900 evidence technician. Describe your packaging and chain-of-custody handling.

Packaging:
- Pistol: unloaded, action open if it can be done safely, in a rigid cardboard box or heavy paper - not a sealed plastic bag, which traps moisture and rusts the weapon. Never scratch or engrave the frame; tag it with a zip tie through the trigger guard.
- Magazine and loose rounds: separate containers, described on the tag.
- Towel and plastic bag: paper bags or boxes individually, so trace evidence and touch DNA are not cross-contaminated.
- Phone: do not power it on or off casually; place it in a Faraday bag or, if unavailable, document its state carefully and keep it off the network. Record whether it was ringing, the screen state, and the times.
Chain of custody: one case number, sequential item numbers, description, where found, from whom, date and time, and a signature at every handoff. If the items sit in a temporary locker for 40 minutes, that is fine - write down who had the key and when you transferred. The gap between your shift end and the technician's start is only a problem when it is undocumented.
3. Can you look through the phone to identify the owner? What are the limits, and how would you write this up?

No warrantless search of the phone.
- The phone was abandoned in a public place, which may affect standing, but it is in your custody and the contents are not a search incident to anything. A ringing phone does not create an exigency by itself; answering it could destroy evidence and mislead the investigation.
- Do this instead: record the number displayed on the screen if visible, photograph the screen, preserve the device, and apply for a warrant describing the phone and what you expect to find (ownership, communications about the firearm, location data if relevant).
- The firearm has its own investigative path: an e-trace request, a check for stolen status, and a request for any nearby camera coverage along the bicycle route.
Report structure:
- Chronological narrative in the first person: call, contact, observations, photographs taken, items recovered, who handled what.
- A separate evidence/property sheet with matching item numbers.
- A short paragraph on the video: who has it, how it was preserved, and any clock discrepancy.
- Facts and observations only. Write 'the pistol contained one round in the chamber' - not 'the suspect discarded a weapon,' because you do not yet know who the suspect is.
