The Criminal Investigation

To provide thorough, accurate, and unbiased criminal investigations related to a police officer's use of deadly force, and other qualifying events resulting in death or substantial bodily harm. The criminal investigation seeks to determine whether or not the officer(s) acted within the law.  

The investigative process should include:

The initial briefing;

Collective Bargaining Unit briefing;

Investigators viewing of body worn camera/dash camera and 3rd party surveillance video;

Viewing of body worn camera/dash camera video by involved-witness officers prior to a walk-through;

Scene walk-throughs by involved-witness officers, crimes scene investigators & administrative investigators;

Countdowns/Photographs of involved-witness officers;

Bookings or arrests made by criminal investigators;

Crime scene documentation;

Area canvass for witnesses or 3rd party surveillance;

Incident debrief with administrative investigators;

Attending autopsy;

Meeting with family members of decedent/suspect;

Involved officer(s) voluntary statement;

Witness officer(s) statement


The Administrative Investigation

Conducts non-criminal, administrative examinations of uses of deadly force or other high-risk police operations as directed by the sheriff or chief. The purpose of this review is to improve individual and agency performance through the evaluation of decision making, tactics used, supervision, and the actual use of force. Conclusions are then presented to the head of agency that may identify possible training needs (for the individual member, squad, unit, section, or on a department-wide basis) and/or changes to policies and practices.

The administrative process should include the following processes:

Involved officer interview;

Witness interviews;

72 Hour Sheriffs / Chiefs briefing;

Employee notification of administrative investigation;

Crime scene diagrams;

Radio traffic analysis;

Training records;

Body worn camera analysis report;

Section manuals;

Critical incident review process to include boards covering the actual use of force and tactics used.

Care & Control of the Involved Officer(s)

The care and control of involved officers is a critical process that must take place to ensure the involved and witness officers receive the internal support from the agency. Guiding an involved officer through the intense processes of criminal investigation to administrative review, to psychological assessment post shooting and lastly return to duty training, should fall under a section that can track and assist and support officers who has been involved in critical incidents.

Return to Duty

The rigorous process of providing support and guidance to officers who have been involved in critical incidents. Returning to duty means that an officer has been cleared criminally, administratively, psychologically and lastly, received the training he/she needs in order to return to duty successfully.
