Efficiency in Processing Sexual Assault Kits

A report funded by the National Institute of Justice and prepared by researchers at RTI International examines the most efficient practices for submitting and processing sexual assault kits (SAKs), and provides recommendations based on findings from surveys of crime laboratories and law enforcement agencies, and site visits with six jurisdictions that included a law enforcement agency, its corresponding laboratory, and a prosecutor's office.

The report, "Efficiency in Processing Sexual Assault Kits in Crime Laboratories and Law Enforcement Agencies," written by Kevin J. Strom, Josh A. Hendrix, William J. Parish, and Patricia Melton, was compiled over the course of a two-year mixed-methods study that was conducted in three phases.

From the abstract:

Unsubmitted sexual assault kits (SAKs) that accrue in U.S. law enforcement agencies (LEAs) have been the subject of increasing attention for the past decade, as have untested SAKs pending analysis in crime laboratories. The field needs a research-informed approach to identify the most efficient practices for addressing the submission of SAKs in LEAs and the testing of SAKs in laboratories. This approach would also determine whether specific policies or characteristics of a jurisdiction result in more efficient processing outcomes. This mixed-methods study examined intra- and interagency dynamics associated with SAK processing efficiency in a linked sample of crime laboratories (N = 145) and LEAs (N = 321). Relying on responses to a national survey of laboratories and a matched sample of LEAs, researchers at RTI International used regression analysis and stochastic frontier modeling to assess how labor and capital inputs, evidence policies, evidence management systems, and models of cross-agency coordination affect SAK processing efficiency. Semistructured interviews with personnel from forensic laboratories, LEAs, and prosecutor’s offices in six jurisdictions were used to elaborate on critical themes relating to SAK processing efficiency.

Lifting Latent Fingerprints from Difficult Surfaces

ALMOST ANYONE can find, process, and lift a latent print that happens to be in a logical and obvious place like a door handle, a beer can, or a butcher knife. But sometimes, a latent print is not just sitting there in a logical and obvious place. Sometimes, you have to use your imagination to find the print and your skills to lift it.
