Evidence Processing

Evidence Processing
Crime Scene Investigators are responsible for examining all evidence, including but not limited to vehicles, guns, and documents for latent fingerprints (fingerprints left behind after touching an object) and for comparing known prints to the latent prints in an attempt to identify a suspect.  The investigator must keep abreast of the latest techniques for development of latent fingerprints, including chemical formulas, alternate light sources (lasers) and photographic techniques that may enhance the latent fingerprint being developed.  A fingerprint is the most positive form of identification and is powerful evidence when presented to a jury during a court trial.  The investigator is also trained to examine evidence for blood, hair, soil, and fibers in an attempt to link a suspect to a crime.

2017 Facts and Figures:

  • Approximately 3,371 items of evidence were processed for fingerprints, DNA, and trace evidence by the Crime Lab from 1,667 cases.
  • In that year, there were also 7,847 latent fingerprints that were compared with suspects.
  • Of those same latents, 304 were identified to a specific person.
  • Our Forensic Data Services Unit processed 342 cell phones, 52 computers and 44 videos from various cases.
