Crime Scene Unit

The Smith County Sheriff's Office Crime Scene Unit is comprised of one Sergeant and three Criminalists.

Criminalists are responsible for assisting in criminal investigations by effectively documenting, collecting and analyzing the photographs, latent prints and other physical evidence present at crime scenes and other locations. Criminalists receive forensic training from state and federal agencies in forensic disciplines which include latent fingerprints, photography, evidence collection and crime scene reconstruction and processing.

Criminalists receive certification to operate the Automated Fingerprint Identification System (AFIS) and Integrated Automated Fingerprint Identification System (IAIFIS), state and national databases storing inked fingerprint records used to match to unknown prints lifted at crime scenes for positive identification.

The Smith County Sheriff's Office Crime Scene Unit also assist other local, state, and federal agencies with crime scene processing, latent print collection, and positive identification through fingerprints.
