    Episode 272 - DNA and Human Factors Expert Working Group Report

    This super-sized episode has the guys interviewing several people from a recent Expert Working Group on Human Factors in the discipline of DNA. Glenn starts by giving Eric his “Where in the Whorld” question and they catch up on some recent travels. Glenn also explains why this episode does NOT feature a continuation of the previous episode on the Peacemaker case, but instead pivots to a different DNA topic. In May 2024, NIJ/NIST released a Human Factors and Forensic DNA Interpretation report. (The) Niki Osborne, Ph.D., the project lead and contractor for NIST (Natl Institute of Standards and Technology) describes how the project came to be and how NIST selected the Expert Working Group (EWG). Then, two members of the EWG, Jarrah Kennedy, Assistant DNA Supervisor, Kansas City Police Crime Laboratory, and Michelle Madrid, DNA Technical Leader, Los Angeles County Sheriff’s Department, discuss the various recommendations in the report. The group covers all sorts of fun topics within DNA discipline such bias, new software and computational approaches, activity level, implementation, enforcement, and so forth. The episode ends with Niki and Glenn discussing other disciplines and future reports. Links to the free report: Expert Working Group on Human Factors in Forensic DNA Interpretation (May 2024).

  2. Episode 271 - SD v Peacemaker Case and Anjali Ranadive Interview

    MAY 6

    Episode 271 - SD v Peacemaker Case and Anjali Ranadive Interview

    Eric and Glenn start the episode with a Where in the Whorld that leads to a little catching up. Glenn was in NYC recently (saw the Harry Potter show on Broadway, indulging his “magician” side) and Eric has been doing the conference circuit. Eric is also soliciting fingerprint experts for a research project on ‘estimating image resolution’ based on ridge density. The guys also got a listener voicemail that they discuss (and roundly disagree with). Finally they discuss the main topic for the show, a homicide case and trial that Glenn testified in: South Dakota v. Jeremiah Peacemaker. Glenn covers his involvement and the fingerprint evidence. In the second half of the show, the guys welcome Anjali Ranadive, who was the DNA expert for the defense, to discuss the DNA evidence and testimony in the case. Both Anjali and Glenn had an opportunity to witness the DNA testimony at trial and were astounded by the “scientific conclusions” drawn, and testified to, by the DNA analyst.
