1. Biology:
* DNA analysis: Used for identification, paternity testing, and linking suspects to crime scenes.
* Bloodstain pattern analysis: Interprets bloodstains to reconstruct crime scenes.
* Botany: Examines plant material for clues.
* Entomology: Uses insect activity to estimate time of death.
2. Chemistry:
* Toxicology: Analyzes body fluids for drugs, poisons, and other substances.
* Trace evidence analysis: Identifies and compares materials like fibers, paint, and glass.
* Firearms analysis: Examines bullets, casings, and firearms.
* Explosives analysis: Investigates explosives and their residues.
3. Physics:
* Ballistics: Analyzes the trajectory and impact of bullets.
* Accident reconstruction: Determines the cause and sequence of events in accidents.
* Sound analysis: Analyzes audio recordings for evidence.
4. Geology:
* Soil analysis: Compares soil samples from crime scenes to those found on suspects or vehicles.
* Mineral analysis: Identifies minerals and their origin.
5. Anthropology:
* Forensic Anthropology: Examines skeletal remains to identify individuals and determine cause of death.
6. Psychology:
* Forensic Psychology: Evaluates criminal behavior, assesses competency, and provides expert testimony.
7. Computer Science:
* Digital forensics: Investigates computer systems and digital media for evidence.
8. Engineering:
* Forensic engineering: Investigates failures of structures, products, or systems.
9. Medicine:
* Forensic Pathology: Performs autopsies and determines cause of death.
* Forensic Odontology: Identifies individuals based on dental records and analyzes bite marks.
While these are some of the major fields, forensic science also employs various other scientific disciplines, depending on the specific investigation. It's a constantly evolving field that adapts to new technology and challenges.
