Capabilities and Services
The primary function of the Forensic Biology discipline is the identification of biological material and the use of DNA analysis to determine whether the biological material could have originated from a specific individual.
The Forensic Biology discipline provides the biological screening and DNA analysis of forensic casework, to include criminal paternity/maternity cases and missing person investigations. Scientific laboratory reports are issued to the investigating agencies.
The laboratory also performs DNA analysis of offender/arrestee samples for entry in the Combined DNA Index System (CODIS). CODIS hit letters are issued to notify law enforcement when there is a DNA match between samples in the DNA database. CODIS hits are investigative leads, typically identifying a potential source of biological material from crime scene evidence.
DNA recovered from an article of clothing in an effort to identify the wearer of the garment.
Y-Chromosome DNA (Y-STR DNA)
Male specific DNA found in the nucleus of most cells of the body. Y-STR analysis is used to amplify locations on the Y chromosome and Y-STR data can only be obtained from male individuals. This type of DNA is inherited paternally. This type of testing may be useful when samples are mixtures of male and female DNA or when there is very little DNA from a male contributor. Y-STR testing has its limitations since close male relatives will have the same Y-STR profile.
Swabs from an item of evidence, such as the mouth of a bottle or an area of the grip of a firearm of no value for latent print examination, can be submitted for DNA analysis while the actual item of evidence can be submitted for examination by the Latent Print or Firearms disciplines
