Case Processing and Human Factors at Crime Laboratories

Type: Webinar
Research Area: Latent Print

This CSAFE Center Wide Meeting Webinar was presented by Dr. Daniel Murrie and Dr. Sharon Kelley from University of Virginia on May 4, 2017.

Description:
Examining case processing to gauge the basic reliability of latent print examination is a crucial step in understanding and improving the statistical foundations for pattern evidence. It allows for better measurements of effective laboratory performance, the effects of altering case management procedures, and assessment of examiner-specific error rates. This presentation will focus on case processing of latent prints at the Houston Forensic Science Center.
