Evidence backlogs have been known to be an issue in crime laboratories. A recent study published by NIJ has shown that backlogs of untested evidence are also an issue in law enforcement evidence storage. This panel will discuss the issues and present preliminary findings from a study of the Los Angeles Police Department's and Los Angeles County Sheriff's Department's experience with clearing out a large backlog of unanalyzed rape kits.
Familial DNA searching is the practice of creating new investigative leads in cases where DNA evidence found at the scene of a crime strongly resembles that of an existing DNA profile but is not an exact match. Panelists will explain how the technology works, provide examples of successful convictions obtained through familial searches, and discuss the various misconceptions and concerns regarding this practice.
