Implementation of forensic DNA analysis on casework evidence at the Palm Beach County Sheriff's Office Crime...

Palm Beach County is the largest of the 64 counties in the state of Florida, USA, with most of the area uninhabited and the population concentrated near the coastal region. The Serology/DNA Section of the Palm Beach County Sheriff's Office (PBSO) Crime Laboratory serves a community of approximately one million residents, and an additional million tourists visit Palm Beach County every year. In addition to the unincorporated county regions, there are thirty-four city police agencies, the Florida State Highway Patrol, several university security agencies, the local Federal Bureau of Investigation, and the county Medical Examiners Office that all use the PBSO Serology/DNA Laboratory for the analysis of casework evidence. The purpose of this manuscript is to provide laboratories that are in the process of initiating DNA analysis on casework with practical information regarding the decision-making processes that occurred during the development of the DNA testing program at PBSO. Many of the concerns addressed in the early 1990's are still a guide to the development of a quality forensic DNA analysis program in the year 2001. Issues, such as personnel, laboratory space, internal standard operating procedures, implementation of DNA analysis on casework evidence, and building a relationship with law enforcement personnel are discussed.
