Frequently asked Questions

Forensic Firearm Analysis is the process of reconstructing the shooting scene and the examination of the characteristics of firearms, fired projectiles and cartridges left behind at a crime scene. 

Tool mark comparisons are defined as the impression left by the contact of a tool (or a similar object) onto a surface. When the tool or object contacts the surface with sufficient force to create an indentation, the pattern of the tool is permanently reproduced onto that surface.

Examples of Physical matches are pieces of broken glass, torn paper tape or clothing, or any other object that can be broken forcibly into parts.

It records and analyzes impressions of vehicle Tyre treads for use in legal proceedings to help prove the identities of specific vehicles at a crime scene.

Identification include but are not limited to: ear tags, ear notches, back tags, neck chains, tail tags, freeze brands, hot-iron brands, tattoos, paint marks, leg bands and electronic identification (e.g., electronic ear tags, microchips and electronic collars).

DNA profiling involves obtaining a specific DNA pattern, or profile, from body tissues.  Forensic Scientist compare DNA found at a crime scene to DNA samples taken from suspects to assess their likelikhood of involvement in the crime.

Bloodstain pattern analysis is crucial in Forensic Science as it reconstructs bloodshed events by examing the size, shape and distribution patterns of bloodstains at crime scenes, providing important Forensic information about the crime under investigation.

Fingerprint Investigation is an evaluative method of finger, palm, or foot friction ridge identification based on scientific principles and procedures that have been established and verified through years of research.

Shoe prints are the impressions or image left behind by a person walking or running.   Impressions are evidence that are made by a suspect’s shoe at a scene of crime (It may be two or three dimensional). Footwear may also contain other material (trace evidence such as blood, soil ext.) that may also link a suspect to a scene of crime. A suspects DNA links him to the footwear.

Polygraph examinations, commonly known as lie detector tests, are used to verify a person’s truthfulness by recording physiological responses to questions.  These responses, such as changes in blood pressure and breathing help determine whether someone is telling the truth or lying.


A Question Document investigation is an in-debth look into a document that is being questioned in the case of fraud, forgery, etc.

Digital Forensics involves investigating electronically stored data for legal purposes.  It is vital because electronic evidence plays a critical role in criminal investigations, civil litigation, and cybersecurity, helping uncover digital evidence and providing insights for legal proceedings.
