Serology / DNA Unit

The Serology/DNA Unit analyzes evidence for the presence of biological material to develop DNA profiles. The analytical process is divided into two primary activities, screening and profiling.  Screening involves examination of evidence items collected from crime scenes to locate biological evidence that is probative to the resolution of the crime.  Once probative biological evidence is located, a DNA profile is developed to compare to a known source, such as a suspect or victim, or uploaded into the Combined DNA Index System (CODIS) for searching against State and Federal databases of known offenders.
