Crime Scene Investigators
Six patrol officers are specially trained as Crime Scene Investigators (CSIs). Their forensic training includes methods and uses of special powders and dyes to raise latent fingerprints, collection and preservation of all types of evidence, and documentation of crime scenes, using digital photography and video.
The CSIs are trained by the Rhode Island State Crime Lab at the University of Rhode Island's Kingston Campus.
The two-semester course entitled Criminalistics I & II covers photography, latent fingerprint lifting and classification, crime scene sketching, evidence collection, and several special presentations by professionals from all over Rhode Island on technical or specialized topics.
Following the completion of training, crime scene investigators are assigned to patrol shift work. Two CSIs are assigned to each of the three patrol shifts. They are called to all crime scenes which require evidence processing, to ensure the proper preservation of physical evidence, which facilitates successful prosecution of criminal cases.
When not processing crime scenes, the CSIs supplement the regular patrol beats and assist in responding to calls for service.
