Accident Reconstruction & Forensic Mapping Services
Expert Analysis for Complex Cases
Gerald McDevitt provides forensic reconstruction, mapping, and expert witness services for attorneys, insurers, and agencies. Each case is analyzed using accepted scientific methods and documented for litigation and courtroom presentation. Services are provided from the Charleston, South Carolina area to attorneys, insurers, and agencies nationwide.

Additional Capabilities
In addition to core services, Gerald McDevitt provides specialized support across a range of complex investigative scenarios.
Emergency Vehicle Operations Analysis
Emergency vehicle operations analysis evaluates response driving, pursuit conditions, and incident dynamics within agency policies and accepted practices. Gerald McDevitt applies accepted scientific methods to assess vehicle dynamics, driver actions, warning device usage, and roadway conditions.
The analysis addresses whether the response was consistent with established standards and operational guidelines, and is documented so each step can be examined and explained in testimony.
Occupant Kinematics & Injury Pattern Analysis
Gerald McDevitt performs occupant kinematics analysis — determining occupant position, movement, and seating during the collision sequence, including driver identification — as part of the standard reconstruction methodology. Injury patterns documented in medical records and photographs are compared with occupant position and vehicle interior contact damage to test seating and driver-identification conclusions. Human factors analysis, including perception-reaction time and driver behavior evaluation, is also within his scope of practice. For cases requiring injury causation analysis or biomechanical body modeling, McDevitt and Associates, Inc. coordinates with a qualified biomechanical specialist identified and approved by retaining counsel.
Cold Case Reconstruction
Older cases often rely on limited and outdated materials — typically photographs, witness statements, police reports, and other historical records. Gerald McDevitt accepts cold cases where the available material is sufficient to support a reconstruction, applying current methods to legacy evidence. Where the record will not support a reliable conclusion, he says so.
Critical Incident Response
Rapid deployment is available for time-sensitive incidents where immediate documentation is needed to preserve perishable evidence. This includes on-scene measurements, photographic documentation, and preliminary analysis before conditions change. Early involvement captures evidence that would otherwise be lost, and supports a more complete reconstruction from the earliest stages of an investigation.
Data Integration & Analysis
All available data sources — scene measurements, vehicle damage, EDR data, and digital mapping — are analyzed together rather than in isolation, so conclusions rest on the totality of the evidence. Where independent data sources agree, that agreement is documented; where they conflict, the conflict is identified and addressed rather than set aside.
Nationwide & Remote Case Support
Services are available nationwide and overseas, in person and remotely. Remote consultation, data review, and analysis allow a case to move forward regardless of location, and on-site deployment can be arranged for scene documentation when a case requires it. Gerald McDevitt has testified overseas, including in Germany and Panama.
Technology-Driven Analysis
Gerald McDevitt uses Recon3D handheld LiDAR scanning, a Sokkia reflectorless total station, Emlid Reach RS3 GNSS, an Autel EVO II Pro RTK V3 drone for aerial photogrammetry, a Racelogic VBOX GPS data logger for speed and motion data, and FARO Zone 3D Expert Plus for diagramming and analysis. Each measurement is documented so it can be examined and reproduced.
