Lecture 3 & 4: Classification of Crime Scenes

Crime Scene Management: Types of Crime Scenes

Classification based on location:
- Primary crime scene: The location where the crime occurred, containing the most direct evidence (weapons, body fluids, footprints). Examples include a murder scene, theft, or assault.
- Secondary crime scene: A location related to the crime, but not where it occurred. It may contain evidence linking the suspect or victim to the primary crime scene. Examples include a location where stolen goods are stored or a car used to transport a victim.
Classification based on geographical area:
- Macroscopic: Large-scale crime scenes involving the entire location, such as a park or house that was involved in a crime.
- Microscopic: Crime scenes containing evidence, like blood splatter patterns, fibers, or hair, on a smaller scale within a larger location.
Classification based on physical location:
- Outdoor: A crime committed in a wide-open area like a field, park, or road.
- Indoor: A crime committed in an enclosed area such as a room, hall, or corridor.
- Mobile/Conveyance: A crime committed in a vehicle like a car, train, bus, or plane, including vehicle burglary, car theft.
Classification based on Mode of Crime:
- Violent Crimes: Include murder, assault, homicide, sexual assault, and domestic violence.
  - Homicide: Crime scene example: A home where a murder occurred.
  - Sexual assault: Crime scene: Location where a sexual assault occurred.
  - Domestic Violence: Crime scene: A home where physical abuse or an altercation occurred.
- Property Crimes: Include burglary, arson, and theft
  - Burglary/Theft: Crime scene examples include a store or bank where a robbery occurred.
  - Arson: Crime scene example: A building or vehicle set on fire.
- Cyber Crimes: Include hacking, identity theft, or online fraud involving a computer or smartphone.
- Drug-Related Crimes: Include drug trafficking and clandestine drug labs. Financial records related to drug activities may be important.
