The recent trials in the U.S. of Patrick Leon Nicholas for the rape and murder of Sarah Yarborough and Gary Hartman for the rape and murder of Michella Welch continue to highlight how FIGG can be a powerful investigative lead generation tool. The use of FIGG, however, raises questions for forensic scientists, prosecutors and defense attorneys as these cases progress through the judicial system. For example, as seen in the Yarborough admissibility (Frye/Kelly or Daubert) hearings will occur, particularly on the application of statistics and as they apply to FIGG. Additionally, the Hartman case raised issues on standing, technology use and privacy, especially as they relate to the tradeoffs during suppression motions. 
On this webinar, experienced prosecutors and forensic scientists discuss the current issues raised regarding FIGG and how such issues were similarly addressed in cases and court decisions from the past and present. The webinar will address common questions raised, statistics, expert testimony, as well as best practices for presenting FIGG in court. Resources will include transcripts of testimony from historical and recent cases. 




Anne Marie Schubert

Retired Sacramento County District Attorney.

Anne Marie Schubert has over 32 years of law enforcement experience and is a nationally recognized expert in forensic DNA. She was elected District Attorney for Sacramento County, California in 2014 and served in this capacity until December 2022. Notably, in 2018, her office led the investigation and prosecution of Joseph DeAngelo, the “Golden State Killer using Forensic Investigative Genetic Genealogy (FIGG). Since the arrest of DeAngelo, her team has used FIGG to identify the NorCal Rapist, unidentified human remains and partnered with the California Innocence Project to exonerate Ricky Davis after 15 years of wrongful conviction. Today, she is nationally recognized in her knowledge of forensic DNA and has trained law enforcement across the world on the use of Forensic investigative Genetic Genealogy (FiGG) to solve violent crime, exonerate the innocent and identify human remains. 

Ms. Schubert has advanced cutting-edge DNA technologies for nearly three decades.  This includes conducting one of the first DNA admissibility hearings on the validity of PCR based DNA evidence in California, resulting in a published appellate opinion.  She pioneered the use of John Doe DNA warrants in 2000, a practice since upheld by the California Supreme Court and now routinely used throughout the country. In 2002, she formed Sacramento’s Cold Case Prosecution Unit, and served as its first prosecutor, solving, and prosecuting several high-profile cases including the rape and murder of Deborah Chandler by convicted serial killer Wilbur Jennings aka “The Ditch Bank Killer.”  

Anne Marie has been recognized with the Prosecutor of the Year Award and the POST ICI Instructor of the Year Award.
