The Division of Forensic Sciences (DFS) has implemented a new DNA interpretation technology, Probabilistic Genotyping [i.e. STRmix™]. Probabilistic genotyping is a method of evaluating DNA results that utilizes more information from DNA profiles and advanced computing methods to assist the DNA Analyst in the interpretation of forensic DNA typing results. As a tool, probabilistic genotyping provides statistical weight in the form of a likelihood ratio to generated conclusions. To assist with this transition in technology the DFS will be offering several 4 hour training sessions for law professionals working in the criminal court settings.
The training session is intended to provide awareness and understanding education (LAU) related to the implementation of probabilistic genotyping [STRmixTM] technology. The training sessions will review the statistical methods and provide a basic overview of probabilistic genotyping as well as offer an introduction to associated DFS procedures and reporting. All impacts of the new technology on investigations prior to and through court proceedings will also be discussed. Training will include examples of effective court questions and the opportunity for open discussion with Forensic DNA Analysts from the DFS.
