摘要

Over the past ten years, the number of individuals with DNA profiles in the National DNA Index System (NDIS) has risen dramatically. Although most of these profiles belong to convicted offenders whose DNA was collected following case disposition, a growing portion of these are associated with individuals whose DNA was collected at arrest or charging. This emerging practice, authorized through legislation passed by Congress and 28 states throughout the country,1 is designed to add value to criminal investigations by increasing the number of profiles associated with individuals whose arrests do not result in conviction, either because no charges are filed, charges are dismissed, or the individuals are found not guilty or are convicted of a non-qualifying offense. In theory, some of these profiles will match with profiles generated from crime scene evidence in NDIS and solve more cases, faster. Despite their prevalence, very little is known about arrestee DNA laws, their implementation in the field, and their subsequent effects on agency operations and public safety. To address this research gap, the National Institute of Justice provided funding for the Urban Institute (UI) to conduct a study that examined (1) key provisions in arrestee DNA laws, (2) how those laws are being implemented across the country, and (3) the effects of arrestee DNA collection on the growth of databases, the number of hits generated through matches to arrestee profiles, and other measures of effectiveness. UI researchers used complementary data collection methods, including a review of relevant literature, case law, and statutes; interviews with state and federal CODIS laboratory staff, key public safety stakeholders, and other forensic experts; and an analysis of data collected from laboratories and other data sources.
