From first attending officer, to investigative officer then SOCO (Q12) Flashcards
Initial action
Preserve life, scan for immediate risks (e.g. fire), call in additional back up if needed
Initial assessment
Preserve the scene and avoid contaminating it:
Using cordons or scene guards. Establish a common approach path where we pave a pathway towards the crime scene that doesn’t compromise the evidence (e.g. separate way from the suspect breaking into the crime scene). Establish cold (outside cordon), warm (place to transition, e.g. where you put on the PPE, where exhibits are, access to tools, etc.) and hot (where you collect evidence from).
Reconnaissance
Walk through the scene and gather information (e.g. witnesses, CTV)
Preliminary reconstruction
Initial hypothesis and also discuss with other experts present
Forensic strategy
Formal or informal plan - of the evidence, what should be cleared, what should be left, etc.
Have resources using people or equipment and plan how to use accordingly.
Review options and order of examination
Scene examination
- Photograph and document scene
- carry out forensic examination
- visual searching
- carry out presumptive tests (e.g. COMBUR) on the scene
- collect evidence
- document the collected evidence properly (establish chain of custody)
As more information is shed, update reconstruction
