Criminalistics



The Criminalistics section has two major functions:

 

  • Analysis of diverse types of physical evidence such as hairs, fibers, firearms, and physiological fluids 

  • Examination of crime scenes


This may include the processing of the entire crime scene or technical assistance to agencies upon request. Staff members also provide expert testimony of findings in court proceedings.

This section provides physical evidence examination to all governmental agencies in Contra Costa County and the City of Vallejo in Solano County. The majority of the casework is performed for City Police Departments and the Office of the Sheriff.
