Litigation Support

Cellular records analysis and expert witness consulting.

Call Detail Records (CDR), Historical CSLI examination, Cell Site analysis (tower, sector, call activations, timing advance), timeline correlation, and litigation-ready expert testimony — for criminal defense, civil litigation, and corporate matters where cellular evidence is in issue.

3-SECTOR SITE // SCHEMATICillustrative

On the limits of cellular geolocation. All findings are based on available carrier records, analytical methodologies, and contextual data. Location analysis contains inherent technical limitations and should be interpreted within the scope of evidentiary standards and investigative context. CyberD20 does not overstate certainty, and presents methodology, assumptions, and limitations alongside every conclusion.

Methodology

Carrier records, examined the way they should be.

Call Detail Records (CDR)

Subscriber records, Call Detail Records (CDR), and per-carrier data — normalized, validated, and cross-referenced.

Historical CSLI analysis

Historical cell-site location information examined against tower configuration, sector orientation, and coverage characteristics.

Cell Site analysis

Tower, sector, call activations, and timing advance — antenna configuration, sector coverage, and propagation factors interpreted against the relevant time period and environment.

Movement reconstruction

Sequence of cell registrations interpreted to construct a defensible — and appropriately bounded — movement narrative.

Timeline correlation

Cellular events correlated against other evidence — communications, financial activity, surveillance, and witness accounts.

Co-location analysis

Examination of whether two devices were plausibly within the same coverage at a given time, with appropriate caveats.

Digital evidence interpretation

Device artifacts, app data, and platform records integrated with cellular data into a coherent evidentiary picture.

Litigation support

Pre-trial consulting, opposing-expert review, deposition preparation, and exhibit-grade visualization.

Expert witness consulting

Independent, defensible expert testimony — written and oral — at the standard the matter requires.

Exhibit-grade visualization

Timeline reconstruction, presented for the courtroom.

EXHIBIT // TIMELINE — ILLUSTRATIVEredacted · sample

Inputs

Carrier-produced CDR, NELOS / per-call measurement data, tower configuration tables, billing records.

Outputs

Written report, courtroom exhibits (timeline, sector overlay, co-location maps), and oral testimony when retained.

Standards

All conclusions express methodology, assumptions, and limitations. Probabilistic where appropriate; definitive only where evidence supports it.

Engagement

Engaged by counsel — for either side.

Criminal defense

Independent review of state cellular evidence; opposing-expert analysis; defense exhibits.

Civil litigation

Whereabouts disputes, employment matters, family-law cellular evidence, insurance investigations.

Corporate & internal

Internal investigations involving cellular records, with counsel privilege and discretion preserved.

Court venues · Idaho-primary

— Idaho state district & magistrate courts
— U.S. District Court · District of Idaho
— Ninth Circuit Court of Appeals

— Mountain West venues (MT, WY, UT, NV, OR, WA) on case-by-case

Working relationships

Established working relationships with Idaho law enforcement, county prosecutors, and the criminal defense bar — engagements move at the right speed when investigation, subpoena, or expert-designation timelines compress.

Out-of-state expert work undertaken case-by-case through counsel referrals and prior relationships.

Fee structure — available upon consultation. Expert witness and cellular analysis engagements are billed against a written retainer agreement scoped to record volume, jurisdiction, deposition/trial exposure, and timeline. Hourly and flat-fee structures available. Conflict checks performed at intake; written engagement letters required before any privileged review begins.
