Case Experience
Extensive Forensic Reconstruction Experience
Gerald McDevitt provides forensic reconstruction services across a wide range of collision investigations — including passenger vehicles, commercial trucks, fleets, motorcycles, pedestrians, and multi-vehicle incidents. Each case is analyzed using scientifically accepted methodologies and advanced forensic technology to deliver accurate, defensible findings for attorneys, insurers, and investigators.
Types of Cases Handled
Passenger Vehicle Collision
The majority of serious and fatal collisions involve passenger vehicles. Gerald McDevitt reconstructs the full sequence of events — pre-impact speed, braking, evasive action, point of impact, and post-impact movement — using physical evidence, roadway data, and vehicle EDR information to produce findings that withstand courtroom scrutiny.
Pedestrian / Bicyclist Accident
Pedestrian and bicyclist collisions require specialized analysis of impact dynamics, throw distance, point of impact, pre-impact visibility, and lighting conditions. Gerald McDevitt has extensive experience with pedestrian fatality cases involving complex impact kinematics, conspicuity analysis, and driver perception-response evaluation.
Motorcycle Collisions
Motorcycle collisions present unique reconstruction challenges including pre-impact positioning, rider behavior, roadway surface conditions, and vehicle-to-vehicle contact geometry. Gerald McDevitt applies validated methodology to determine speed, point of impact, and causation — findings that are defensible under Daubert and Frye admissibility standards.
Commercial Vehicle Accident
Commercial vehicle collisions — involving tractor-trailers, delivery vehicles, buses, and fleet vehicles — frequently involve federal regulatory compliance issues, electronic logging devices (ELD), and complex vehicle dynamics. Gerald McDevitt reconstructs these incidents with the same scientific rigor applied to all casework, including EDR and ECM data extraction.
Military Court-Martial (UCMJ)
Gerald McDevitt provides forensic reconstruction analysis for UCMJ court-martial proceedings involving vehicular manslaughter (Article 119), negligent homicide (Article 134), Vehicular Homicide & Felony DUI, and related offenses. Gerald McDevitt is a U.S. Air Force veteran who has been qualified as an expert in U.S. military courts. Retainer waived for UCMJ cases.
Hit-and-Run
Hit-and-run reconstruction requires identifying a suspect vehicle through trace evidence, damage patterns, paint transfer, and scene geometry. Gerald McDevitt documents and analyzes all available physical evidence to establish vehicle contact signatures, direction of travel, and post-impact departure path — providing investigators and attorneys with scientifically supported conclusions.
DUI / Vehicular Homicide
Cases involving alcohol or drug impairment and a resulting fatality require reconstruction that accurately establishes pre-impact speed, braking behavior, reaction time, and causation. Gerald McDevitt’s analysis is structured to meet the evidentiary demands of criminal prosecution and defense, with findings expressed to a reasonable degree of scientific and engineering certainty.
Low Delta-V / Disputed Injury
Gerald McDevitt reconstructs low delta-V collisions using scientifically accepted analysis methods to evaluate the forces involved and occupant kinematics — including occupant position and movement during the collision sequence. For cases that specifically require injury causation opinions or biomechanical body modeling, McDevitt and Associates, Inc. coordinates with qualified biomechanical specialists identified and approved by retaining counsel.
Courtroom & Expert Witness Experience
Gerald McDevitt has been qualified and accepted as an expert witness in multiple jurisdictions, including state, federal, and U.S. military courts.
His testimony is supported by scientifically accepted methodologies and structured to meet Daubert and Frye admissibility standards.
Federal & Military Investigations
Gerald McDevitt was assigned to the ATF National Response Team for the forensic mapping of the Charleston Sofa Super Store Fire, a multi-fatality line-of-duty incident in which nine firefighters were killed. He has also provided forensic reconstruction support to federal agencies and U.S. military investigations on cases requiring precise scene documentation and reconstruction analysis.
Service Area & Jurisdiction
Based in Mount Pleasant, South Carolina (Charleston metro area), Gerald McDevitt provides services nationwide. Gerald McDevitt has conducted casework across multiple jurisdictions, supporting attorneys and agencies at both local and national levels.
Approach to Investigation
Gerald McDevitt approaches each case with a focus on objective analysis, measurable data, and scientifically validated methodologies. Multiple data sources are evaluated, including physical evidence, digital data, and scene measurements, to develop a complete and accurate reconstruction.
