Attribution of files and accounts to a specific user, timeline reconstruction from system artifacts, deleted data questions, and the reliability of law enforcement extraction reports and hash based identification.
Civil litigation
Trade secret and data exfiltration questions, USB and cloud sync history, spoliation analysis, and authentication of messages, documents, and metadata under Federal Rules of Evidence 901 and 902(14).
Family law
Message authenticity, device access and shared account questions, location questions from device and carrier records, and allegations of stalkerware or unauthorized monitoring.
Cell site and location
What carrier call detail records can and cannot establish about a phone's location, the difference between a serving sector and a precise position, and the limits of coverage mapping presented as proof of presence.
Testimony formats
Deposition
Pretrial testimony on methodology, findings, and the reliability of the underlying data sources.
Evidentiary hearing
Testimony on admissibility, authentication under Federal Rule of Evidence 902(14), and the integrity of the acquisition.
Trial
Direct and cross examination before a jury, with exhibits built from the examined data rather than from narrative summaries.
Recognized digital forensic expert witness
Recognition in this field comes from repeat retention and from findings that survive cross examination. Casey Gallagher is a recognized digital forensic expert witness among defense counsel, civil litigators, and businesses who need an examiner willing to state the limits of the data rather than the conclusion the retaining party hoped for.
Working principles
- The evidence sets the conclusion. The retaining party does not.
- Every finding must be reproducible by another qualified examiner from the same image.
- Absence of an artifact is not proof of an act. It is reported as absence.
- Original media is preserved, and analysis runs against verified images.
- If a question cannot be answered reliably with the available evidence, that is the answer given.
