The Crime Scene Investigation Unit is one of the most challenging, interesting and complicated jobs in the Police Department. Our investigators are highly trained in crime scene investigations and evidence collection. They work closely with the lead detective at a major crime scene to collect and document all relevant evidence. Crime scene investigators are requested by the first-responding officers to collect evidence of a crime.
Members of the CSI Unit respond to a wide variety of crimes from burglaries to homicides. The crime scene investigator must evaluate the minute details of a crime scene and determine what types of processing are appropriate. Processing a scene can include the use of digital photography, the recovery of latent fingerprints, the collection of DNA or serological evidence and the collection of foot, tool or tire impressions.
All police officers must attend a basic crime scene class as part of their required training. Uniformed officers serve as crime scene generalists collecting and documenting any of the following:
Crime scene investigators, however, must train constantly to keep abreast of new techniques in evidence recognition, recovery and proper collection. Most crime scene generalists and CSI investigators are recruited from the Patrol Division.
