Collection and Preservation of Evidence at Crime Scenes

In the role of a crime scene investigator, one of the most crucial tasks is collecting and preserving evidence found at crime scenes.

• Procedures Followed to Ensure Integrity of Evidence:
  
  
• Upon arrival at the crime scene, the investigator must first secure the area to prevent contamination of evidence.
  
  
• Photographs are taken to document the scene before any evidence is collected to ensure an accurate record.
  
  
• The investigator must wear appropriate protective gear to avoid tampering with evidence or leaving any traces behind.
  
  
• All evidence is carefully marked, labeled, and packaged to maintain its integrity and prevent cross-contamination.
  
  
• Chain of custody forms are filled out to track the movement of evidence from the crime scene to the laboratory for analysis.
  
  
• Importance of Chain of Custody in Court Testimony:
  
  
• Chain of custody refers to the chronological documentation of the handling of evidence to ensure its integrity and admissibility in court.
  
  
• It serves as a crucial link that establishes the continuity and authenticity of evidence presented during the legal proceedings.
  
  
• The chain of custody helps to prove that the evidence presented in court is the same evidence collected at the crime scene without any alterations.
  
  
• It provides a clear record of who had possession of the evidence at all times, ensuring its reliability as legal proof.
  
  
• Without a properly maintained chain of custody, the integrity of the evidence may be called into question, leading to its inadmissibility in court.
  
  

Overall, the collection and preservation of evidence at crime scenes are fundamental tasks for a crime scene investigator. The adherence to strict procedures and chain of custody guidelines is essential for the successful presentation of evidence in court.
