The Miami-Dade Crime Lab is a scientific laboratory located in Miami, which uses primarily forensic science for the purpose of examining evidence from criminal cases.
Employees of the Crime Lab are known as criminalists; this includes both CSIs doing mostly field work and lab techs doing mostly lab work. Miami CSIs wear guns in the field and some of them are detectives, unlike the CSIs from the Vegas crime lab.
