The DNA Unit began processing forensic casework using DNA technology for Broward County in 1993. Today, it provides comprehensive serological and DNA analysis of biological evidence to support criminal investigations throughout Broward County. These services assist the Broward Sheriff's Office and all municipal law enforcement agencies in solving a wide range of cases, including homicides, sexual assaults, robberies, burglaries and other violent crimes.

Analysts examine a variety of evidence types—such as swabs, stain cuttings, cigarette butts, hairs and skeletal remains including bone and teeth—to detect the presence of DNA. When viable, these samples are used to generate DNA profiles that can link individuals to criminal activity. The unit continuously enhances its capabilities by implementing cutting-edge technology and automation to extract, purify, quantify and analyze DNA with precision and efficiency.

DNA profiles developed from evidence are compared to known reference samples and results are interpreted by trained analysts who prepare detailed reports and provide expert witness testimony in court. The unit also contributes to the Combined DNA Index System (CODIS), a nationwide network of DNA databases maintained by forensic laboratories across the United States. CODIS enables the comparison of forensic DNA profiles against local, state and national indices, helping law enforcement agencies generate investigative leads and solve cases.

For cases involving homicides and sexual assaults where no initial CODIS match is found, the unit may pursue additional investigative support through Familial Searching—a process coordinated with the Florida Department of Law Enforcement (FDLE) that searches for potential relatives of the source of the unknown DNA. This approach offers new avenues for identifying suspects when conventional database searches are inconclusive.

In addition to standard forensic testing, the DNA Unit offers specialized services upon request, including Y-STR (Y-chromosome Short Tandem Repeat) analysis, which is particularly useful in cases involving male-specific DNA and forensic genetic genealogy—a powerful investigative tool used to identify potential suspects or unidentified remains through distant familial relationships.

These advanced capabilities allow the DNA Unit to support complex investigations and provide meaningful leads in challenging cases, reinforcing its commitment to scientific excellence and justice.
