Patrol Investigation:
Shall, where an investigation reveals that offences have been committed by more than one party, proceed with charges as appropriate. In making such determinations, Officers shall assess and identify the dominant aggressor if possible, using the Investigative Aid, "Identifying the Dominant Aggressor" found on the HPS Intranet, as a tool to assist in determining the dominant aggressor.
When the dominant aggressor is unable to be determined and dual charges are being considered, Officers shall notify a DVO trained Patrol Supervisor. The Patrol Supervisor shall attend the scene and consult with the Investigating Officer to ensure a thorough investigation has been conducted and appropriate charges are laid in the circumstances.
All reports, including those resulting in dual charges, shall be sent to the Intimate Partner Violence Unit task box in the Niche RMS.
Dominant Aggressor: defines the individual who has been the principal abuser (not necessarily the person who initiated the violence).
