CSI and The Role of the Crime Scene Investigator.

Crime Scene Investigation Overview

• Historical Context:

  • Rise of CSI in the 1980s with advancements in technology (e.g., AFIS, DNA profiling)

  • Landmark cases (e.g., first use of DNA in murder case, 1987)

  • Influence of TV series on public perception and academic registrations

  • Increase in enrollment into forensic science programs (e.g., 30% increase in applications)

  • Establishment of dedicated crime scene facilities (e.g., Trent University)

Critical Concepts in Crime Scene Investigation

• Locard's Exchange Principle:

  • Definition: "Every contact leaves a trace"

  • Implications: When two items come into contact, an exchange of material occurs; foundational idea in forensic science.

• Definition of a Crime Scene:

  • Any physical location that may yield evidence of a crime; includes vehicles, buildings, open-air locations, etc.

  • Digital/e-crimes require different investigative approaches.

Social Implications of Crime Scene Investigation

• Contemporary Challenges:

  • Proliferation of social media affects crime scene control

  • Real-time information dissemination can compromise investigations

  • Officers must manage public information effectively during incidents

• Incident Command Structures:

  • Collaboration among various agencies (Law Enforcement, Fire, EMS, HazMat) during incidents

Evidence in Crime Scene Investigation

• Definition of Crime Scene Evidence:

  • Physical items that may provide connections between individuals and objects; examples include fingerprints and DNA.

  • Such evidence is highly valued in court as "real evidence."

Role of Crime Scene Investigators

• Responsibilities:

  • Locating, documenting, and collecting evidence

  • Generating investigative leads through physical evidence

  • Requires specialized training and adherence to the Police Services Act of Ontario

  • Importance of maintaining objectivity and independence from the lead investigator

  • Mismanagement of evidence can lead to wrongful charges or misapplied justice

Case Studies

• Brenda Waudby: Wrongful conviction case due to mishandling of evidence during the investigation of her daughter’s murder (Peterborough, 1997).

• Paul Bernardo and Karla Homolka: Significant evidence missed during the investigation led to the eventual discovery of crucial video tapes that impacted the case (St. Catharines, 1993).

Scope of Crime Scene Investigations

• Investigation Goals:

  • Generate leads through identifying and collecting evidence

  • Determine the extent of the crime scene to establish boundaries

Forensic Identification Services (FIS)

• Role and Responsibilities:

  • Support police agencies as needed; level of response governed by policy

  • Responsibilities include recording, documenting, evidence collection, and court testimony

  • Must avoid tunnel vision and maintain independence from front-line officers

Evolution of Forensic Roles

• Historical Context:

  • Traditionally, forensic officers were primarily police officers who transitioned from patrol duties

  • In recent years, the number of civilian forensic staff has increased significantly

• Current Trends:

  • Civilianization of forensics is on the rise, with civilians taking on roles traditionally held by police officers

Career Opportunities in Crime Scene Investigation

• Current Job Openings:

  • Example: Hamilton Police Service hiring Forensic Services Assistants; salary range discussed (83,446 - 98,177 CAD)

• Job Titles in Crime Scene Investigation:

  • Examples: Crime Scene Investigator (CSI), Forensic Identification Officer (FIO), Scenes of Crime Officer (SOCO), etc.

Future Directions in Forensic Science

• Shifts in Role Dynamics:

  • Increasing incorporation of civilian personnel into forensic investigation roles

  • Potential for civilians to replace or complement existing police roles, bringing both advantages and challenges
