Utah Department of Public Safety

Forensic Services - Forensic Biology

The Forensic Biology Section is responsible for the detection, identification, and comparison of biological evidence. This section is staffed by 11 Forensic Scientists both in the Central Lab and Northern Lab. The Forensic Biology Section caseload consists primarily of sexual assault cases and homicides. Occasionally, a burglary, robbery, or assault case might involve biological evidence.

Biological evidence may be present as blood, semen, saliva, hairs, or other cellular material.

When a biology case is analyzed, it typically goes to Serology and then to DNA for comparisson.

SEROLOGY: The detection and identification of bilogical fluids

DNA:  The genetic make-up of living organisms

CODIS: The DNA Database

The DNA profiles from forensic specimens and convicted felons are submitted to a national database.

The Combined DNA Index System -- (CODIS) system is a program that is headed by the Federal Bureau of Investigation - (FBI). The objective of this database is to link serial crimes on a national level, much like the Automated Fingerprint Index System -- AFIS. This system has had tremendous successes by solving several high profile crimes that would otherwise not have been solved.
