The ability of an expert to proffer opinions is governed by rulings such as the Dauberrt and Frye standards. It is your responsibility to both question and research my qualifications to your personal satisfaction.
Services and conclusions will conform to the existing generally accepted procedures recommended by the Association of Firearms and Toolmark Examiners (AFTE) or other scientific organizations and the AFTE Code of Ethics.
SHOOTING RECONSTRUCTION
Review and evaluation of police reports, depositions, autopsy photos and medical examiner reports, crime scene reports and photos, lab reports, interview reports, diagrams, notes, evidence collection procedure, grand jury testimony, ballistics reports.
Results and conclusions may conflict with what the evidence reveals. Crime scenes are the foundation of evidence collection. When it is improperly processed, or evidence is not collected, conclusions can be skewed. I have processed or been a supervisory officer at more than 750 crime scenes and realize the importance of thorough work.
The lack of evidence can be as important in proving or disproving facts of the case.
Accidental discharges, although uncommon, do occur. Accidental discharges can be the result of human error, defective firearm mechanisms, design flaws, neglect, negligence, improper training, malfunction. Accidental discharges can be both voluntary and involuntary.
FIREARMS AND AMMUNITION EXAMINATIONS
Function, operation, trigger pull, design defects, accidental discharge and shootings, ammunition.
 
TOOLMARKS AND FORENSIC MICROSCOPY
Microscopic comparison of cartridge cases and projectiles in compliance with the AFTE Theory of Identification and Procedures Manuals.
 
Microscopy on tools, burglarious instruments to evidence objects, crimping tools and seals.
 
GUNSHOT DISTANCE DETERMINATION
The goal is to conduct tests which will approximate the distance from the object or victim that was shot to the muzzle end of the suspect firearm. Certain facts of the case can be proven or disproven when these tests are performed using the methods generally accepted within the discipline.
TRAJECTORY AND TERMINAL BALLISTICS
Complex issues may be involved in computing trajectory and terminal ballistics unless certain facts can be determined to ensure reliability and validity of conclusions. Factors include distance, angle, topography, velocity, weather and environmental conditions and the unique elements of the specific ammunition. The ballistic curve is different for each combination of caliber, bullet weight and shape.
