Identification System (AFIS). The AFIS system has a database containing
more than 680,000 fingerprint cards from both counties. Using this
database this Section:
-
Searches rolled fingerprints to discover a list of
candidates, which may contain the identity of any person arrested or
booked in Contra Costa County.
-
Searches latent fingerprints (fingerprints developed
on evidence gathered at crime scenes) against the database in order to
discover possible candidates who may have been involved in the
perpetration of a crime.
-
Once candidates have been located in the AFIS system,
the fingerprints submitted by the arresting police agency are compared
by Fingerprint Technicians or Fingerprint Examiners to master
fingerprint cards on file. The fingerprint comparison is done to
positively establish a subject's identity.
