    Episode 275 - 2024 IAI Conference: The Reno Recap

    The guys start out with a quick explanation of why Glenn’s sound is so bad (he’s in Switzerland recording). They also start the new “season”, post-IAI with a new game: "Truth, Lie, or Mandela Effect?" Eric talks about his fall conference junket and then the guys finally catch up on the IAI. They discuss their favorite lectures, workshops, and activities at the 2024 IAI Conference in Reno, NV. They summarize some of their standout lectures that they attended. Glenn then discusses how the Double Loop Podcast vendor booth went with Rebecca Coutant running it during the conference. Rebecca also was “Our Girl Friday”, doing her impromptu interviews with conference attendees.

    Episode 274 - NIST Inconclusive Paper

    Eric and Glenn are back from a little summer break, prepping for the 2024 IAI Conference in Reno. They do a final “Where in the Whorld?” game. Then they jump into a recent paper on “Inconclusive” decisions (Swofford, et al. (2024) “Inconclusive Decisions and Error Rates in Forensic Science”, Forensic Science International: Synergy (vol 8; 100472)) authored by several members of NIST. The paper proposes a method for computing and communicating error rates when “inconclusive” decisions are made. The paper also focuses on making clear distinctions between “method performance” versus “method conformance”. The guys discuss their views on the method and the implications the paper may have for fingerprint examiners and their agencies.

    Episode 273 - Angela Hilliard Interview - Erroneous Exclusions

    Glenn and Eric are joined by Angela Hilliard to discuss her experiences with a cold case from the Pacific Northwest. Genetic genealogy provided a suspect's name from a cold case double homicide, and a latent palm print was left on the victim's van. Angela walks us through her initial erroneous exclusion, the subsequent identification, court testimony, and the resulting press coverage. A must-listen episode for examiners on how to handle erroneous conclusions, even in high-profile cases. (Apologies for the audio in this episode. We did not realize until later that some of audio was poorer quality than normal.)

    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).

    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.

    Episode 270 - The TFSC Report and the Webster Case - Pt 2

    Today Eric and Glenn finish Part 2 on the 2023 Report of the Texas Forensic Science Commission dealing with a latent print case. They continue to discuss the TFSC report that followed an investigation into a complaint filed against the latent print contractor(s) in the Joseph Webster case. In part 2, the guys focus on Glenn's examination which concluded that the Webster palm mark was a complex mark and that 3 critical things will shape the conclusion rendered by an examiner: 1) which images were used; 2) which features were relied upon; 3) how the examiner applied the ACE-V methodology. Finally, they discuss the over 2 dozen recommendations that the Commission made for fingerprint examiners in Texas to follow in latent print examinations. www.txcourts.gov/media/1457617/fi…-as-of-12623.pdf

    Episode 269 - The TFSC Report and the Webster Case - Pt 1

    Today Eric and Glenn start Part 1 of a two-parter on the 2023 Report of the Texas Forensic Science Commission dealing with a latent print case. First the guys do some catching up and play Where in the Whorld. They also discuss an email from Simon Cole and inquire on the impact of the recent AI paper on fingerprints. Then they discuss the TFSC report that followed an investigation into a complaint filed against the latent print contractor(s) in the Joseph Webster case. The webster case was a homicide cold case that eventually broke with a CODIS hit and a subsequent apparent bloody palm print at the scene of the crime. Initially the palm print was not identified to Webster, but then after the CODIS hit occurred to Webster and a second person, the latent print evidence was re-visited in 2013, and an identification was declared (pursuant to reviewing additional palm print exemplars of Webster). Testimony occurred in 2016 by a project manager, but not any of the original examiners. In 2020, a contractor for the defense was hired to review the case and several examiners were unable to verify the identification. This conflict, as well as a review of the testimony, sparked a complaint to the TFSC in the case. The guys review the facts and details of the case in Part 1.
