Crime Scene Unit

The Crime Scene Unit is responsible for assisting the Detective Bureau, Special Victims Unit and the Crash Reconstruction Unit with the processing of major scenes for forensic evidence. The Unit members have extensive training in all facets of forensics such as latent print development and analysis, photography, use of alternate light sources, ballistic testing, serial number restoration, shoe and tire impression casting and forensic mapping. In February of 2023, the Unit acquired the Faro 3D scanner system to replace the Total Station for mapping Crime and Crash scenes.  Currently, the two members have over 60 years of combined law enforcement experience.  

The Crime Scene Unit also processes evidence collected by Detectives or Patrol Officers from scenes in a state of the art processing room that includes a Fuming Chamber, Dusting Room and Bullet Trap for test fires. The Unit regularly processes evidence for surrounding Police Departments and Federal Agencies as requested.
