Study Notes
Introduction to Forensic Science
- Forensic science applies scientific methods to legal matters.
- It uses various disciplines to investigate crimes and collect evidence.
- It aims to provide objective and scientifically sound evidence for justice.
Crime Scene Investigation
- Systematic crime scene investigation is essential.
- Initial steps include documenting layout, condition, and securing the area to prevent contamination.
- Evidence collection adheres to protocols to preserve integrity.
- Evidence types include physical traces (fingerprints, blood, fibers), biological samples (DNA), and impressions (footwear, tire marks).
Fingerprint Analysis
- Fingerprints are unique patterns on fingertips, invaluable for identification.
- Techniques include dusting, lifting, and chemical enhancements.
- Automated Fingerprint Identification Systems (AFIS) are used for comparison and searching.
DNA Analysis
- DNA, deoxyribonucleic acid, has unique genetic information for individuals (except identical twins).
- DNA profiling extracts and analyzes DNA from biological samples (blood, saliva, hair).
- DNA evidence establishes or excludes suspects, identifies victims, and traces familial relationships.
Ballistics
- Ballistics studies the motion, behavior, and effects of projectiles (bullets).
- Firearms identification determines the weapon type.
- Trajectory analysis reconstructs a projectile's path.
Trace Evidence
- Trace evidence includes small items (fibers, hairs, glass, paint, soil).
- Analysis links suspects to crime scenes or eliminates them as suspects.
Toxicology
- Toxicological analysis detects drugs or poisons in bodily fluids or tissues.
- Results determine cause and manner of death.
- This is crucial in poisoning or overdose cases.
Document Examination
- Document examination analyzes documents (signatures, handwriting, typewriting).
- It assesses authenticity and determines if a document is genuine or forged.
Pathology
- Forensic pathology examines cause and manner of death via autopsy.
- Pathologists use methods like microscopy to determine injuries and death causes.
Odontology (Forensic Dentistry)
- Forensic odontology identifies individuals via unique dental structures.
- Dental records are compared to skeletal remains or other evidence.
Entomology (Forensic Entomology)
- Forensic entomology studies insects to determine time since death.
- Insect infestation and development stages are key factors.
Audio and Video Analysis
- Forensic audio and video analysis examines audio and video recordings.
- Sounds and images can help establish events and provide detail.
Digital Forensics
- Digital forensics analyzes digital evidence (computers, phones).
- This includes data recovery, image analysis, and network forensics.
Other Forensic Disciplines
- Other disciplines contribute (anthropology, geology, engineering).
Challenges and Limitations
- Maintaining evidence's chain of custody is crucial.
- Forensic evidence can be contaminated, degraded, or misinterpreted.
- Interpreting evidence demands expertise and considering many factors.
- Technological advancements drive ongoing development.
