Awareness of the Potential of the EDD Serving as a Source for Transfer of DNA
By: Diane K. Tolliver and Carl A. Sobieralski
Abstract
Electrostatic Detection Devices (EDD) have the potential to collect and transfer DNA1 during processing. “Touch DNA” can now be detected and interpreted under current DNA processes at the Indiana State Police Laboratory. Analysis is by capillary electrophoresis with the PP16 kit2 (Promega PowerPlex 16 kit). The EDD bed and humidification chamber were examined for the presence of DNA sources from shed cells. This research examined whether or not EDD processing of documents may be a source of cross-contamination. The 2008 American Society of Questioned Document Examiners (ASQDE) conference theme, “Reasoning with Technology: A Cognitive Approach to Casework,” was applied in this research in examining whether or not the forensic document examiner needs to heighten his/her sense of awareness of possible DNA cross-contamination issues when examining documents using the EDD.
