The Detective Bureau serves as the main investigative branch of the Department. Detectives and officers assigned to the bureau conduct follow-up investigations for criminal cases and respond to crime scenes when requested. Each case is reviewed for solvability factors and assigned to an investigator for follow-up based on the type of crime.
The primary function of the detective bureau is to conduct follow-up investigations of reported crimes. These investigations consist of interviewing suspects, victims, and witnesses; analyzing information for validity, reliability, and accuracy; and compiling a comprehensive and factual case file to be presented in court.
The detective bureau is also tasked with crime analysis, surveillance in areas of criminal activity, monitoring, and maintenance of registered sex and drug offenders, narcotics investigations, and background investigations for alcohol, massage, and public safety volunteers. The Criminal Investigations Division is responsible for the receiving, processing, storing, and purging of property/evidence collected by officers during the course of their duties. The integrity of the chain of custody and the integrity of the evidence/property room is critical for the successful prosecution of criminal cases.
