1. Introduction to Forensic Science Fundamentals
Forensic science is the application of scientific methods to legal problems. It is a multidisciplinary field that draws on a variety of scientific disciplines, including biology, chemistry, physics, and computer science.
Forensic science is used in a wide variety of criminal investigations, including homicides, assaults, robberies, and burglaries. Forensic scientists can help to identify suspects, link them to crimes, and reconstruct the events that led to the crime.
Branches of Forensic Science, Forensic science fundamentals and investigations answer key
- Forensic biology: the study of biological evidence, such as blood, DNA, and hair
- Forensic chemistry: the study of chemical evidence, such as drugs, explosives, and poisons
- Forensic physics: the study of physical evidence, such as fingerprints, firearms, and tool marks
- Forensic computer science: the study of digital evidence, such as computer files, emails, and social media posts
2. Crime Scene Investigation
The crime scene is the location where a crime has occurred. It is important to preserve the crime scene so that forensic scientists can collect evidence and reconstruct the events that led to the crime.
Methods of Documenting the Crime Scene
- Photography: taking photographs of the crime scene and any evidence that is found
- Sketching: drawing a diagram of the crime scene, including the location of any evidence
- Note-taking: writing down observations about the crime scene, including the location of any evidence
