Sexual Assault: Obtaining DNA From Evidence Collected up to a Week Later

June 2009

Technological advances have made it possible to detect male DNA in evidentiary samples collected several days after a sexual act has taken place. Panelists will present the research that has led to these findings, followed by a discussion of the potential impact of this work from the perspectives of the sexual assault nurse examiner (SANE) and the crime laboratory communities.

"Sentinel Event" Review in the Criminal Justice System

January 2014

Listen to James Doyle discuss the basics of a "sentinel event" review in the criminal justice system. This learning-from-error approach borrows from principles that medicine, aviation and other high-risk enterprises have successfully used.
