Study Notes
Types of Evidence in Forensics
-
Direct Evidence
- Links a defendant directly to a crime without inference.
- Example: Eyewitness testimony.
-
Circumstantial Evidence
- Implies a person committed a crime based on surrounding circumstances.
- Example: Witnesses observing a defendant fleeing a crime scene.
- Requires multiple pieces of evidence for a substantial impact.
-
Physical Evidence
- Material objects involved in litigation.
- Common types: Weapons, shoe prints, tire marks, and fibers from clothing.
-
Individual Physical Evidence
- Features unique to a specific source.
- Examples: Fingerprints, DNA, and striation marks on bullets.
-
Class Physical Evidence
- Associated with a group rather than an individual.
- Used to narrow down suspects or items.
- Examples: Blood type, shoe tread patterns, firearm make and model.
-
Forensic Evidence
- Scientific evidence developed through the scientific method.
- Generally accepted in the scientific community.
- Includes DNA matching, fingerprint identification, hair and fiber analysis.
-
Trace Evidence
- Created from contact between two objects.
- Examples: Gunshot residue, hair, fibers, soil, and pollen.
- Links individuals to specific locations.
-
Testimonial Evidence
