Digital Evidence Models

Investigation Event Record

Digital investigation events can be represented as actor, device, account, source, and review records. Honesty note: simplified US federal classroom model; Fourth Amendment doctrine and state rules vary; the pinned first step states the as-of date; not legal advice.

Start with an event record

The stated process stores a digital investigation event as actor label, device or account label, event date, source, and review-status fields.

Example event packet

The toy event date is May 12, 2026. The classroom log includes a device-event row and an account-event row.

event date=May12,2026\text{event date}=May 12, 2026

The table recomputes support

The retrieval table recomputes 2 records and 2 token-supported rows from the authored event text.

Summary

Digital evidence workflows should expose actor, device, account, date, source, and review fields before any gate trace.
