Crime Scene Investigations Unit is comprised of fifteen full time,
certified police officers. The unit
is a sub-division of the Criminal
Investigation Division of the police department and consists
of two Lieutenants, two Sergeants and eleven Investigators and
provides services for the county as well as the cities of Riverdale,
Forest Park and Jonesboro.
The Investigators are responsible for detecting, documenting,
collecting, processing and preserving evidence from crime scenes.
Each Investigator is trained in multiple disciplines including
fingerprint comparison, crime scene processing, blood stain analysis,
footwear comparison, death investigation, DNA collection, profiling
sexual predators, and a vast amount of other training utilizing
state of the art equipment.
Each investigator is required to compare the fingerprints obtained
on the crime scenes they investigate and give expert testimony
in court concerning positive identifications of fingerprints from
those crime scenes. Fingerprint identifications play a major role
in criminal apprehensions and convictions.
The Clayton County Police Department Crime Scene Investigations
Unit is one of many police agencies in the metro Atlanta area
to possess an A.F.I.S. (Automated Fingerprint Identification System)
terminal. Once fingerprints are collected from a crime scene and
a comparison is made to the victim for elimination purposes, the
fingerprints are searched against the criminal database of fingerprints
in the state of Georgia. The database contains the known fingerprints
of approximately 3,000,000 criminal offenders and a search of
the unknown fingerprints collected at a crime scene to the fingerprints
in the database can usually yield a match within 15 minutes if
the offender's fingerprints are on file. The system is also searched
to help identify unidentified dead persons.
