Evidence Management

"In order for qualified forensic science experts to testify competently about forensic evidence, they must first find the evidence in a usable state and properly preserve it.”

- National Academy of Sciences, Strengthening Forensic Science in the United States: A Path Forward (2009)

Evidence management is a critical facet of the criminal justice system. At every stage, handlers of evidence must ensure that it has not been compromised, contaminated, or degraded and that its chain of custody is tracked. The criminal justice system’s growing reliance on forensic evidence in casework adds complexity to the already difficult job of managing vast inventories of property and evidence held by law enforcement agencies.

The NIST Forensic Science Research Program, in collaboration with the National Institute of Justice, as well as a host of other organizations, committee members, and state and local governments, have established a role in the development of research and guidance in the management of evidence. Long standing expertise in the stability and degradation of various materials and advanced technological capabilities make NIST a unique partner in developing innovative perspectives in addressing evidence management challenges.
