Study Notes
Types of Evidence at Crime Scenes
- Physical evidence includes fingerprints, hair, fibers, and weapons.
- Biological evidence often consists of blood, saliva, or other bodily fluids.
- Trace evidence refers to minute materials transferred during a crime, such as gunshot residue.
Crime Scenes with Blood Stains
- Homicide scenes frequently exhibit blood due to violent altercations.
- Assault and battery incidents often result in blood presence.
- Accident scenes, such as vehicle collisions, may also show blood.
Serology in Forensics
- Serology is the study of blood and bodily fluids in forensic contexts.
- It involves the identification of blood types and possible diseases through fluid analysis.
- Serological tests can ascertain the origins and characteristics of biological evidence.
Bloodstain Pattern Analysis
- Bloodstain pattern analysis (BPA) examines the shape, volume, and distribution of blood stains.
- BPA helps reconstruct the events that led to the bloodshed.
- Techniques used include examining the size and location of stains to determine impact angle and forces involved.
Paternity Testing through Blood Examination
- Blood tests can determine genetic markers to establish biological relationships.
- Specific antigens in blood can be analyzed to identify paternal connections.
- Paternity tests can yield a high probability of parentage based on blood type compatibility.
