Study Notes
Crime Scene and Investigation Overview
- Crime scenes are defined as any location where a crime has occurred, potentially including buildings, vehicles, or outdoor spaces.
- A secondary crime scene can refer to evidence or a victim moved from the original location.
- Forensic science, meaning "before the forum" in Latin, is crucial for validating crime-related events through scientific examination.
Historical Context
- The first documented use of forensic science was in 44 BC when Julius Caesar was assassinated; physician Antistius performed an autopsy.
- The concept of forensic examination emphasizes the importance of physical evidence in legal proceedings.
Roles and Processes in Investigation
- Various roles are involved in a crime scene investigation, including Scenes of Crime Officers, SIOs, crime scene coordinators, and forensic lab personnel.
- Investigations follow a structured flow: crime scene to officers, forensic support unit, laboratory, and court presentation.
Forensic Science and Evidence Management
- Evidence must be carefully collected and preserved; continuity tracking is essential to show evidence integrity.
- Quality assurance in forensic processes ensures compliance with established codes of practice.
- The UKAS (United Kingdom Accreditation Services) provides accreditation, but not all organizations are accredited.
Types of Crimes
- Volume crimes (e.g., street robberies, burglaries) occur frequently and significantly impact communities.
- Serious crimes involve violence or financial gain, including arson, robbery, and sexual assault.
Major Crimes and Investigation Protocol
- Major crimes include murder, attempted murder, and terrorism, usually requiring more resources and coordination among various investigative teams.
- The senior investigating officer (SIO) is responsible for managing inquiries and coordinating efforts within the investigation team.
Crime Scene Management
- Crime scene managers supervise investigation teams, delegate tasks, and ensure compliance with health and safety protocols.
- Each officer at the scene must avoid cross-contamination and adhere to ethical and legal standards throughout the investigation.
Key Investigation Questions
- Investigators must consider the following critical questions:
- What are the aims of the investigation?
- Who is the victim?
- When and where did the crime occur?
- What sequence of events transpired?
- What was the criminal's modus operandi?
Importance of Context and Trace Evidence
- Contextual information regarding where evidence is found is vital since some evidence cannot be accurately timestamped.
- Edmund Locard's exchange principle asserts that every contact leaves a trace, facilitating connections to crime scenes.
Best Practices for CSIs
- Crime Scene Investigators (CSIs) must work methodically, ethically, and communicate effectively while remaining impartial.
- A thorough examination and record-keeping during evidence collection are essential for maintaining the integrity of the investigation.
