Exhibits and Evidence Collection

Policy updated: March 2016

Gathering Material Evidence


Investigators are expected to make thorough efforts to gather material evidence pertinent to the case.  Material evidence includes, but is not limited to, video or audio recordings, photographs of evidence or site visits, copies of relevant documents (court records, citations, police reports, BOEC VCAD, medical records, security logs, training records, etc.) and at times physical evidence (such as a torn shirt, broken personal belongings, etc.). 

IPR Investigators may conduct interviews and gather documentation by travelling to the person or the scene, particularly when photographs would aid understanding of the complaint.  They will take into consideration their own safety in the field.

Exhibits and Documentation

IPR Investigators will:

  • Document all attempts to collect material evidence and receipt of such materials in the investigation’s Chronological Record. 
  • Document the person or agency who provided the evidence.
  • For physical evidence, document any available information regarding the individuals who handled or transferred to evidence before it was delivered to the IPR Investigator.
  • List all material evidence as exhibits in the Evidence Collected/Exhibits section of the report.  The report should explain the relevance to the investigation of the evidence listed as exhibits.
  • Save an electronic version of all exhibits to the electronic case file.  Exhibit titles in the electronic file should match the Exhibits section of the report.
