In addition to managing caseloads, investigators and laboratory staff must manage the evidence collected and samples submitted to the laboratory. Best practices for protecting the integrity and value of evidence include:

  • Training personnel associated with the case
  • Reviewing past evidence management issues to avoid repetition
  • Developing and implementing proper storage policies and procedures
  • Ensuring adequate property room facilities
  • Evaluating current packaging techniques to ensure preservation
  • Providing appropriate packaging materials
  • Using proper documentation for chain of custody
  • Using transportation methods that protect the evidence from loss, damage and/or contamination
