Executive Summary

Digital evidence can disappear through routine deletion, account changes, automatic overwriting, or provider retention limits.

Social-media content, cloud files, telecommunications records, application messages, location information, and third-party business records may become unavailable long before the defense is prepared to collect them.

This Authority Publication explains how defense teams can identify potential digital evidence, map its custodians, document retention risks, and preserve relevant records without confusing preservation with legal production.

It emphasizes original sources, traceable collection methods, accurate attribution, and clearly documented limitations.
