Biological Sciences & DNA

 

Biological Sciences:



The Biological Sciences Section of the Crime Laboratory performs analysis of biological material deposited during the commission of crimes such as homicide, sexual assault, home invasion, assault, burglary, and hit and run fatalities in addition to assisting in the identification of human remains by the Medical Examiner.  The evidence is examined for the presence of body fluids such as blood, semen and saliva followed by DNA testing to determine the source of the sample.  Comparison of DNA from a suspect to DNA from the crime scene will either link them to the crime or prove their innocence.  If there is no suspect, the crime scene DNA profile is entered into the FBI’s combined DNA Index System (CODIS) database where it may be linked to other cases or to a convicted offender whose DNA is in the database. Since the Crime Lab joined CODIS in 2000, DNA evidence analyzed by the Biological Sciences Section has aided police agencies in over 1800 investigations.

  analyzed”. Therefore, estimated values have been applied to these standardized statewide definitions.
