In addition to the convicted offenders, there are four other database indexes:
DNA casework analysts type samples for these indexes. Profiles generated from evidence samples are entered into the state database and searched against samples in other indexes as appropriate.
Eligible offender and casework profiles are subsequently uploaded to the National CODIS databank which links information from all fifty states. Investigative leads may be generated at the state or national level as follows:
Scientists in this functional area examine and compare firearms, ammunition components, gunshot residues for distance determinations, and tool marks. These scientists also reconstruct shooting scenes, restore obliterated serial numbers, and image fired ammunition components for inclusion in the Integrated Ballistics Identification System (IBIS)/ National Integrated Ballistics Information Network (NIBIN) for links to other criminal events.
Scientists in this functional area examine and compare trace materials such as hairs, fibers, glass, paint, impression evidence, soils, and other miscellaneous materials. These scientists also examine explosives and post-blast explosive residues, and conduct blood stain pattern analysis.
Scientists in this functional area identify controlled substances, pharmaceuticals, materials from clandestine drug laboratories, ignitable liquids in fire debris, selected poisons, and chemical unknowns.
Scientists in this functional area examine and compare handwriting, hand printing, altered documents, indented writing, machine-generated documents, paper, and ink.
Latent Fingerprint Identification
Scientists in this functional area process evidence for latent prints and compare the prints to those from known individuals. These scientists also enter prints into the Automated Fingerprint Identification System and search a variety of computerized databases for matches to known individuals.
Crime Scene Assistance
Participating scientists provide crime scene assistance to local law enforcement agencies investigating major crimes. These scientists assist the local agency with evidence recognition, evidence collection, blood stain pattern analysis and trajectory determinations, scene documentation, and scene reconstruction.
