Forensic Expert's Role

Forensic Analysis

Examination of physical evidence to determine its relevance to a crime
Includes:
- Chemical analysis of substances (e.g. drugs, toxins)
- Biological analysis of bodily fluids (e.g. DNA, bloodstains)
- Physical analysis of materials (e.g. fibers, paints)
Goals:
- Identify the source of the evidence
- Determine the relevance of the evidence to the crime
- Establish a link between the evidence and the suspect or victim

Scene Reconstruction

Reconstruction of the crime scene to understand the sequence of events
Based on:
- Physical evidence found at the scene
- Witness statements
- Other available information
Goals:
- Establish the timing and sequence of events
- Identify the actions of the perpetrator(s)
- Reconstruct the crime scene to aid in the investigation

Crime Scene Investigation

Systematic and thorough examination of the crime scene
Includes:
- Documentation of the scene (e.g. photographs, notes)
- Collection of physical evidence (e.g. fingerprints, footprints)
- Observation of the scene for potential clues
Goals:
- Preserve and document the crime scene
- Collect and preserve physical evidence
- Identify potential leads and areas for further investigation

Evidence Collection

Systematic and careful collection of physical evidence
Includes:
- Collection of biological fluids (e.g. blood, saliva)
- Collection of physical materials (e.g. fibers, hairs)
- Collection of digital evidence (e.g. computer files, emails)
Goals:
- Preserve the integrity of the evidence
- Ensure the chain of custody is maintained
- Ensure the evidence is suitable for analysis and comparison
