Forensic Investigation Course

Lesson 1 • History and Scope of Forensic Science

Traces forensic science from early identification methods to modern multidisciplinary practice. Establishes context for understanding how each forensic discipline contributes to criminal investigation.

Lesson 2 • Scientific Method in Forensic Practice

Applies hypothesis-driven reasoning to evidence analysis and interpretation. Ensures students approach every examination with structured, reproducible methodology.

Lesson 3 • Legal and Ethical Obligations

Defines the legal duties and ethical standards governing forensic professionals. Grounds students in impartiality, confidentiality, and testimony obligations before technical training begins.

Lesson 1 • Scene Recognition and Initial Response

Covers first-responder priorities: scene safety, perimeter establishment, and preliminary assessment. Connects proper initial actions to downstream evidence integrity.

Lesson 2 • Evidence Search Patterns and Methods

Introduces systematic search patterns to ensure complete scene coverage. Methodical searching prevents evidence loss and supports chain-of-custody integrity.

Lesson 3 • Scene Documentation Techniques

Teaches photography, videography, sketching, and note-taking as complementary documentation tools. Accurate documentation forms the permanent record used throughout prosecution.

Lesson 4 • Chain of Custody Fundamentals

Establishes procedures for collecting, packaging, labelling, and transferring evidence. Unbroken chain of custody is essential for evidence admissibility in court.

Lesson 1 • Paint, Adhesives, and Polymer Evidence

Analyses paint layer sequences, adhesive chemistry, and polymer composition. Findings link vehicles, tools, and surfaces to criminal events.

Lesson 2 • Locard's Exchange Principle in Practice

Applies the transfer-and-persistence concept to real evidence scenarios. Understanding transfer dynamics guides collection priorities and interpretation of trace findings.

Lesson 3 • Glass, Soil, and Mineral Evidence

Examines fracture patterns, refractive index, and elemental composition of glass and soil. These materials provide geographic and contact associations in criminal cases.

Lesson 4 • Fibre, Hair, and Textile Evidence

Covers microscopic and chemical examination of fibres, hair, and fabric. Findings establish contact associations between suspects, victims, and scenes.

Lesson 1 • STR Profiling and Interpretation

Details short tandem repeat amplification, capillary electrophoresis, and profile reading. STR profiling is the primary method for human identification in criminal cases.

Lesson 2 • Statistical Interpretation of DNA Evidence

Applies random match probability, likelihood ratios, and population genetics to DNA findings. Statistical communication determines how juries and courts weigh DNA evidence.

Lesson 3 • DNA Extraction and Quantification

Explains laboratory procedures for extracting and measuring DNA from forensic samples. Quality and quantity of DNA directly affect downstream profiling success.

Lesson 4 • Biological Evidence Identification

Covers presumptive and confirmatory tests for blood, semen, saliva, and other biological fluids. Correct identification determines which samples proceed to DNA analysis.

Lesson 1 • Automated Fingerprint Identification Systems

Explains how AFIS encodes, searches, and ranks candidate prints. Examiners must verify all AFIS candidates using ACE-V before reporting identifications.

Lesson 2 • ACE-V Comparison Methodology

Applies the Analysis, Comparison, Evaluation, and Verification framework to latent print examination. ACE-V is the accepted standard for reaching and documenting identification conclusions.

Lesson 3 • Latent Print Development Techniques

Teaches physical, chemical, and optical methods for visualising latent prints on varied surfaces. Technique selection depends on surface type, age, and environmental conditions.

Lesson 4 • Courtroom Presentation of Print Evidence

Prepares examiners to explain friction ridge evidence clearly to judges and juries. Effective testimony translates technical findings into legally meaningful conclusions.

Lesson 1 • Wound Interpretation and Trauma Analysis

Analyses blunt, sharp, and gunshot wound characteristics to determine weapon type and directionality. Wound patterns corroborate or contradict witness accounts and scene reconstructions.

Lesson 2 • Medicolegal Death Investigation System

Describes the roles of medical examiners, coroners, and forensic pathologists in death investigation. Understanding jurisdictional authority clarifies how forensic examiners collaborate with pathologists.

Lesson 3 • Postmortem Changes and Time of Death

Covers livor mortis, rigor mortis, decomposition stages, and entomological indicators. Accurate time-of-death estimation narrows investigative timelines and suspect windows.

Lesson 4 • Manner and Cause of Death Determination

Distinguishes natural, accidental, homicidal, suicidal, and undetermined manners of death. Correct classification drives the entire investigative and prosecutorial response.

Lesson 1 • Digital Evidence Fundamentals

Introduces data storage concepts, file systems, and the volatile nature of digital evidence. Foundational knowledge prevents inadvertent alteration of evidence during collection.

Lesson 2 • Computer and Storage Media Analysis

Applies forensic tools to recover deleted files, artifacts, and user activity from storage media. Recovered artifacts reconstruct user behaviour and establish timelines.

Lesson 3 • Forensic Acquisition and Imaging

Covers write-blocking, bit-stream imaging, and hash verification to ensure evidence integrity. Verified forensic images allow repeated examination without altering original media.

Lesson 4 • Network and Internet Evidence

Examines IP logs, network traffic captures, and online account records as evidence. Network evidence establishes identity, communication, and criminal activity in cyberspace.

Lesson 1 • Direct Examination and Cross-Examination

Prepares examiners to present findings clearly on direct and withstand rigorous cross-examination. Effective testimony requires both technical accuracy and clear communication under pressure.

Lesson 2 • Documenting Findings and Conclusions

Guides examiners in translating laboratory and scene data into supported conclusions. Conclusions must be traceable to documented observations and validated methods.

Lesson 3 • Principles of Forensic Report Writing

Establishes standards for objectivity, completeness, and clarity in forensic documentation. Well-written reports directly support admissibility and prosecutorial effectiveness.

Lesson 4 • Qualifying as an Expert Witness

Explains the legal standards courts apply when qualifying forensic experts. Meeting qualification criteria is prerequisite to offering opinion testimony in criminal proceedings.
