More About Us

Forensic Ballistic is built on 35 years’ experience of long time forensic ballistic expert (firearm & toolmark examiner) Cobus Steyl. Using objective independent experts with experience brings a check and balance system to technical and scientific evidence already submitted to the court. Attorneys & advocates should have a good working knowledge of the technical information available in order to properly prepare for a case and ensure technical evidence presented by the opposing party is correct in all aspects. Having started in the South African Police Service and most recently running his own private practice for the past 28 years he has accumulated vast professional experience interpreting crime scenes, the related physical evidence and regularly gives advice in court as an expert witness.

Mr. Steyl is actively involved in most aspects of crime scene investigation with a primary focus on firearm & toolmark examinations and analysis, detection and recovery of footwear impressions, examination of crime scenes and/or exhibits for bloodstain evidence according to the established methodology of bloodstain pattern analysis, on request. Other
examinations include but not limited to:
