Serving Legal Teams Across the United States
4D Forensics is rooted in Minneapolis, Minnesota and provides services across the country and internationally. Our work is designed for cases in which recorded media, scene geometry, timing, file integrity, or technical interpretation may affect a legal decision.
Many forensic examinations can begin through secure transfer of the best available evidence and a focused consultation with counsel. Matters involving physical recording systems, 3D scene capture, laser scanning, drone mapping, equipment inspection, deposition, or courtroom testimony may require coordinated shipping or travel.
Location does not change the standard of the analysis. Every engagement begins with the evidence, the question counsel needs answered, and the limits of what the source can reliably support.

How a Nationwide Forensic Engagement Works
1. Initial Case Review
Counsel provides the party names for a conflict check, the jurisdiction, the evidence type, known deadlines, and the technical question that needs to be evaluated. The initial review helps determine whether the issue involves enhancement, authentication, recovery, timing, comparison, reconstruction, visualization, or expert testimony.
2. Evidence Preservation and Transfer
We identify the best available source and any supporting material needed for the examination. Depending on the evidence, this may include original files, native exports, proprietary player software, devices, recording systems, reference images, scene measurements, photographs, reports, or discovery records.
3. Forensic Examination and Reporting
The evidence is examined using methods appropriate to the source and question. The resulting work product may include a written report, technical findings, clarified media, metadata tables, annotated exhibits, synchronized timelines, comparison panels, measurable 3D models, or courtroom demonstratives.
4. Consultation, Deposition, and Trial Support
When included in the engagement, 4D Forensics can assist counsel with technical conferences, discovery questions, deposition preparation, declarations, hearing exhibits, mediation presentations, expert rebuttal, deposition testimony, and trial testimony.

Remote Analysis and Onsite Forensic Services
Many digital media matters can begin remotely because the examiner is analyzing files, metadata, timing, codecs, image content, audio signals, or synchronized sources. A secure transfer and focused case conference can often establish whether the available evidence supports further work.
Some matters require physical or location-based work. Examples include:
-
Inspection or acquisition of a DVR or NVR system -
Forensic imaging of storage media -
Laser scanning or photogrammetry of a scene -
Vehicle or object documentation -
Drone mapping and aerial scene capture -
Camera-position or field-of-view documentation -
Equipment inspection -
In-person deposition, hearing, or trial testimony
The appropriate approach depends on preservation risk, source condition, legal authority, travel requirements, and the questions at issue. Contact 4D Forensics before shipping equipment or making changes to an active recording system.
Frequently Asked Questions About Nationwide Forensic Services
Is 4D Forensics limited to cases in Minnesota?
No. 4D Forensics is based in the Minneapolis, Minnesota area and accepts qualified forensic matters throughout the United States. The work may begin remotely, with travel or physical evidence transfer arranged when the engagement requires it.
Can evidence be reviewed without shipping the original device?
Often, yes. Many examinations can begin with original digital files, native system exports, forensic images, supporting records, and a case consultation. A physical device or recording system may still be required when the file alone does not preserve the necessary data, when recovery is needed, or when the source device is part of the disputed issue.
Can your experts travel for scene work, depositions, or trial?
Travel may be coordinated for laser scanning, scene documentation, equipment inspection, evidence acquisition, deposition, hearing, or trial. Availability depends on scope, timing, location, and the assigned expert.
Do you work in state and federal matters?
4D Forensics can evaluate potential engagements involving state and federal civil or criminal matters when the requested work falls within the laboratory's expertise and there is no conflict. The retaining attorney should provide the jurisdiction, case posture, disclosure requirements, and known deadlines during intake.
How should a law firm begin a case review?
Provide the names of the parties for a conflict check, the court or jurisdiction, the evidence type, the best available source, the relevant date and time range, current deadlines, and the exact question counsel needs addressed. Do not send confidential evidence through an unsecured channel. Request approved transfer instructions before uploading large or sensitive files.
Discuss Your Evidence With a Forensic Expert
A useful forensic engagement begins with a defined question and the best available source. Tell us what the evidence is, where it came from, what has already been done to it, the jurisdiction, and the deadline. We can help identify the appropriate scope for review.
