criminal investigator

What the work can involve

The work starts at the scene: keeping the area protected, observing details, photographing evidence, collecting or preserving material and writing reports that investigators can use. Careful handling matters because later decisions may depend on the condition and documentation of evidence.

Skills and specializations

Useful depth includes crime-scene methods, evidence packaging, photography, chain-of-custody records, forensic awareness, report writing and personal discipline around contamination. Some roles lean toward fingerprints, scene photography, laboratory handover or broader investigative support.

Salary context

Pay comparisons should consider irregular call-outs, exposure to distressing scenes, evidence responsibility, required technical methods, report complexity and independent judgment at a scene. A support role with limited collection duties differs from a lead scene investigator.

Career paths

Experience may develop from police, forensic support or laboratory-adjacent work toward senior scene investigation, fingerprint work, evidence coordination, forensic case support or training others in scene procedures.

Good to know

Check whether a vacancy names crime-scene attendance, evidence collection, photography, contamination control, reports and custody records. Clear wording separates this work from general detective duties or laboratory-only forensic analysis.
