Study Notes
Basics of Forensic Science
- Forensic science applies scientific principles and techniques to solve crimes by collecting and analyzing physical evidence.
- It encompasses various fields, including biology, chemistry, physics, and medicine, to assist in criminal investigations.
- It plays a crucial role in both civil and criminal law systems, supporting investigations and courtroom proceedings.
Father of Forensic Science
- Hans Gross is recognized as the "Father of Forensic Science" for integrating various scientific disciplines into criminal investigations.
- His publication in 1893, "Handbuch für Untersuchungsrichter, Polizeibeamte, Kriminalbeamte", laid the groundwork for modern forensic techniques.
Crime Scene Investigation
- Crime scene investigation (CSI) is the process of collecting and analyzing evidence at a crime scene.
- Key steps include securing the scene, documenting evidence, collecting samples, and preserving the chain of custody.
- Techniques used include photography, sketching, and evidence collection methods to ensure integrity and reliability.
Biological Evidence
- Biological evidence refers to any sample derived from a living organism, such as blood, saliva, or other bodily fluids.
- DNA profiling, a key tool in forensic analysis, helps in identifying or excluding suspects through genetic material analysis.
- Biological evidence can provide critical links between the victim, suspect, and crime scene.
Establishment of Forensic Science Laboratory
- Forensic laboratories are specialized facilities where various types of evidence are analyzed.
- In many countries, the establishment of these labs has significantly enhanced the capability to solve crimes through scientific examination.
- Labs may offer services such as toxicology, DNA analysis, fingerprint analysis, and ballistics.
Biological Evidence
- Biological evidence is crucial for establishing connections between individuals and crime scenes.
- It can be found in various forms, including hair, skin cells, or organic materials.
- Preservation and proper handling of biological evidence are essential to prevent contamination.
Physical Evidence
- Physical evidence encompasses any tangible objects that can be collected from a crime scene, such as weapons, clothes, or tools.
- It aids in corroborating witness statements and reconstructing crime scenarios.
- Physical evidence must be collected, documented, and stored in a manner that maintains its integrity.
Trace Evidence
- Trace evidence is minute materials that can transfer from one surface to another during a crime.
- Examples include fibers, glass fragments, paint chips, and soil.
- Analysis of trace evidence can link suspects, victims, and crime scenes, offering valuable clues.
Fingerprint
- Fingerprints are unique patterns formed by ridges and valleys on fingers, serving as a critical form of personal identification.
- Identification techniques include dusting for prints, chemical enhancement, and digital scanning.
- Automated fingerprint identification systems (AFIS) facilitate the rapid comparison of fingerprints against databases.
Footprint
- Footprints can provide vital clues about a suspect’s movement and physical characteristics.
- Examination focuses on size, tread patterns, and depth of impressions.
- Footprint evidence can tie a suspect to a crime scene or exclude them based on characteristics in the prints.
