The Criminal Investigations Division is under the command of Captain David O'Neil.  The division's main duty is to investigate criminal activity once a crime has been reported. The Criminal Investigations Division also conducts proactive investigations and covert operations in an attempt to deter criminal activity before it occurs. The division periodically works to educate citizens on how to protect themselves from being a victim of a crime. The Brentwood Police Department’s Criminal Investigation Division is also responsible for the processing of major crime scenes and the processing of crime scenes when a crime scene technician is not available or on duty. Detectives are on-call 24 hours a day on a rotating basis.

If you report a crime to the Brentwood Police Department, a patrol officer will normally respond to the location of the crime and complete an offense report detailing the crime. The offense report will then be forwarded to the captain of criminal investigations on the next business day for review. The captain is responsible for determining which reports are assigned to a detective for investigation. Detectives are normally assigned only felony cases, but may investigate misdemeanor cases when deemed necessary. An offense report may also be returned to the patrol division for a patrol officer to conduct an investigation.
