The primary function of a FLO is to act as an investigator and to gain the confidence and trust of the families of victims of murder or manslaughter, road fatalities, mass disasters, rail fatalities, or other critical incidents. The role of a FLO is to gather evidence and information from the family in order to contribute to the investigation and maintain its integrity. The FLO also offers sensitive and compassionate assistance, ensuring that family members receive timely information in accordance with the needs of the investigation, including timely referrals to appropriate support agencies.
