Investigations Division

Captain Chris Amason serves as the Criminal Investigations Commander overseeing the Criminal Investigations Section, the Special Investigations Section, Forensic Services, and the Property Section.

The initial investigation of most crimes is conducted by a uniformed patrol officer, who then files an offense report to document his or her findings. In many cases, the patrol officer is able to complete the investigation, identify the suspects, and make arrests or file charges to close the case. In other cases where there are no arrests or clear leads, or if more in-depth or specialized investigation is required, the case is forwarded to the Criminal Investigations Section.

In the Criminal Investigations Section, two Lieutenants serve as first-line supervisors for 20 authorized detectives.  The Section is divided into two major categories, crimes against person and crimes against property. Two of the detectives who specialize in crimes against children are part of the multi-disciplinary team at the Mary Abbott Children's House

Supervisors in Criminal Investigation Section review each open case received from Patrol to determine whether it will be assigned to a detective for further investigation. Many criteria are considered by the supervisors in making this determination. Solvability factors being whether there are witnesses and/or physical evidence, whether viable leads exist or can be developed whereby to identify the suspect, and the extent of injury and/or property loss. As a rule, essentially all violent crimes against persons, crimes against vulnerable adults, or other incidents of an especially serious nature are assigned or follow-up.

The Special Investigations Section fulfills a unique function within the Department’s organization.  The primary mission of Special Investigations is to avert criminal activity by working in a covert manner and utilizing specialized training and resources. The detectives assigned to Special Investigations are in a unique position to assist other divisions of the department to conduct sensitive investigations in a variety of circumstances. The Special Investigations Section collects intelligence on potential criminal activity provided by the Norman community and other police officers. Detectives begin a basic inquiry technique which establishes the validity of the information and potential assignment as a full comprehensive investigation.
