Forensic Science Course

Lesson 1 • Legal Framework and Admissibility Standards

Examines how courts evaluate scientific evidence and expert testimony. Connects laboratory practice to evidentiary admissibility requirements.

Lesson 2 • Scientific Method in Forensic Contexts

Applies hypothesis-driven inquiry to evidence analysis and interpretation. Reinforces objective reasoning as the foundation of all forensic conclusions.

Lesson 3 • History and Scope of Forensic Science

Traces forensic science from early medico-legal practices to modern multidisciplinary applications. Contextualizes the field's evolution within criminal justice systems.

Lesson 1 • Scene Reconstruction Basics

Introduces logical reconstruction of events using spatial and physical evidence relationships. Builds analytical thinking applied in later advanced reconstruction chapters.

Lesson 2 • Scene Recognition and Safety Protocols

Identifies hazards and establishes safe perimeters before evidence collection begins. Ensures investigator safety and scene preservation from first response.

Lesson 3 • Scene Documentation Techniques

Covers photography, sketching, and note-taking methods for accurate scene recording. Produces legally defensible documentation supporting later laboratory analysis.

Lesson 4 • Collection, Packaging, and Chain of Custody

Demonstrates proper collection tools and packaging materials for each evidence type. Establishes unbroken chain of custody from scene to laboratory.

Lesson 1 • Bloodstain Pattern Analysis

Analyzes bloodstain morphology to reconstruct events and determine directionality. Integrates physics of fluid dynamics with scene reconstruction principles.

Lesson 2 • Biological Evidence Identification

Covers detection of blood, saliva, semen, and other biological materials at scenes. Establishes the basis for subsequent serological and DNA analysis.

Lesson 3 • Biological Evidence Preservation

Addresses degradation factors and optimal storage conditions for biological samples. Ensures sample viability for downstream DNA and serological testing.

Lesson 1 • Forensic DNA Databases and Cold Cases

Explains database architecture, search protocols, and hit confirmation procedures. Demonstrates how database matches reopen unsolved investigations.

Lesson 2 • DNA Extraction and Quantification

Demonstrates extraction methods suited to different sample types and degradation levels. Quantification ensures sufficient template for reliable profiling.

Lesson 3 • Mixture Interpretation and Statistics

Addresses deconvolution of multi-contributor DNA profiles and probabilistic genotyping. Applies likelihood ratios and random match probability to case reporting.

Lesson 4 • STR Profiling and Capillary Electrophoresis

Covers short tandem repeat amplification and fragment separation for profile generation. Produces the numerical profiles used in database searches and comparisons.

Lesson 1 • Pharmacokinetics and Interpretation

Applies absorption, distribution, metabolism, and excretion principles to interpret drug concentrations. Connects measured levels to impairment and cause-of-death determinations.

Lesson 2 • Controlled Substance Analysis

Covers color tests, immunoassay screening, and confirmatory GC-MS analysis of drugs. Connects presumptive and confirmatory results to legal classification.

Lesson 3 • Forensic Toxicology Specimen Collection

Identifies optimal biological matrices and collection timing for toxicological analysis. Proper collection prevents degradation and ensures defensible results.

Lesson 4 • Principles of Analytical Chemistry in Forensics

Reviews separation, identification, and quantification techniques foundational to forensic chemistry. Establishes method validation concepts applied throughout the chapter.

Lesson 1 • Principles of Trace Evidence Transfer

Applies Locard's exchange principle to predict and locate trace evidence at scenes. Establishes the theoretical basis for all comparative trace examinations.

Lesson 2 • Hair and Fiber Examination

Examines morphological and chemical characteristics distinguishing human, animal, and synthetic fibers. Comparative analysis links questioned samples to known sources.

Lesson 3 • Glass, Soil, and Mineral Analysis

Applies refractive index measurement and elemental analysis to glass comparison. Soil and mineral profiling associates samples with geographic locations.

Lesson 4 • Paint, Adhesive, and Polymer Examination

Identifies paint layer sequences and polymer composition using spectroscopic methods. Connects automotive and architectural paint evidence to specific sources.

Lesson 1 • Medicolegal Death Investigation System

Describes the roles of medical examiners and coroners in death certification. Establishes jurisdictional and procedural context for forensic pathology practice.

Lesson 2 • Postmortem Changes and Time of Death

Covers livor mortis, rigor mortis, decomposition stages, and entomological indicators. Applies these findings to estimate postmortem interval in casework.

Lesson 3 • Autopsy Procedures and Documentation

Details external and internal examination protocols and evidence collection during autopsy. Systematic documentation supports cause-of-death determination and court testimony.

Lesson 4 • Forensic Neuropathology and Special Cases

Examines brain injury patterns, shaken impact syndrome, and fire death investigation. Addresses complex cases requiring specialized pathological expertise.

Lesson 1 • Expert Witness Testimony and Report Writing

Develops skills for writing defensible forensic reports and delivering clear courtroom testimony. Prepares students to withstand cross-examination on methodology and conclusions.

Lesson 2 • Advanced Crime Scene Reconstruction

Applies bloodstain, ballistic, and physical evidence data to reconstruct complex events. Builds on earlier reconstruction basics with quantitative and experimental methods.

Lesson 3 • Integrating Multidisciplinary Evidence

Combines DNA, trace, toxicological, and pathological findings into unified case narratives. Demonstrates how convergent evidence strengthens investigative conclusions.

Lesson 4 • Case Studies in Complex Forensic Investigations

Analyzes landmark and instructive cases to extract lessons in evidence management and interpretation. Reinforces integrated analytical skills through real-world problem-solving.
