Turning Base Hits into Earned Runs: Improving the Effectiveness of Forensic DNA Data Bank Programs

Abstract

Forensic data banks contain biological samples and DNA extracts as well as computerized databases of coded DNA profiles of convicted offenders, arrestees and crime scene samples. When used for investigative and law enforcement purposes, DNA data banks have been successful in providing key investigative leads in hundreds of criminal investigations. A number of these crimes would never have been resolved without use of such data banks. In addition, in some limited number of investigations, the exclusion of known suspects whose DNA profiles are known to be in an offender database can save valuable investigative time. Despite the above benefits, in hundreds of cases DNA samples are never collected and administrative and laboratory logjams delay prompt database searches. Furthermore, hundreds of DNA database matches (hits) languish, without any followup by law enforcement or prosecutors. These prevent or delay DNA matches and therefore can leave the public in grave risk of potential harm from recidivistic offenders who otherwise could have been apprehended and convicted if the process functioned more effectively.
