After arguing about the Mandela Effect, Glenn and Eric catch up on some email and discuss ANAB AR3125 7.8.1.2.2 and how this impacts reporting conclusions. Glenn talks about using verbal LRs to express the perceived weight of evidence. Then the guys review a paper from Israel on investigative leads (Attias, et al. 2015) from J of For Sci & Criminology.

Glenn Langenburg and Eric Ray are proud to be joined by Mark Stolorow. Before his years guiding the creation of the OSAC and his days with NIST, he had a varied history getting kicked out of the chemistry department, avoiding the draft, working as a cop, researching blood typing, and wearing plaid jackets. Listen to the interview for all the details of a fantastic career. This episode is sponsored by GO EVIDENCE LABORATORIES.

Eric Ray and Glenn Langenburg are joined for another episode discussing statistics and probabilities by Professor Christophe Champod from the University of Lausanne. Christophe takes us on a history of his work on fingerprint statistics, his past, current, and future research projects, his hope for the future of statistics in fingerprint comparisons, and how the newest Swiss model is available for use through the Pianos software.

Eric Ray and Glenn Langenburg interview Australian researcher Gianni Ribeiro at the December 2018 OSAC meeting in Phoenix, AZ. Gianni tells the guys about her research interests studying how juries weigh evidence vs. alibis and other jury studies. She also talks about her impressions of the experts gathered at the OSAC meeting, the discussions going on related to likelihood ratios, and the battles over issues big and small in various subcommittees.

Glenn Langenburg and Eric Ray are joined in-person by Henry Swofford as they discuss his career with the Army Crime Lab and the development of FRStat, a model that produces a similarity score between two compared fingerprints and a ratio of how that score fits into same source or different source distributions. The guys discuss why the model was developed, how it's being used, and some of the models limitations. This episode is sponsed by GoEvidence Forensic Laboratories, and this episode is also sponsored by IDEMIA.

Glenn Langenburg and Eric Ray are joined by Cedric Neumann to discuss all things statistical models, probabilities, likelihood ratios, Bayes factors, and more. Cedric discusses his history of research, his history in forensics, and how that's brought him from Switzerland to the UK to the US. This episode is sponsored by IDEMIA and their new Case AFIS product.

Eric Ray and Glenn Langenburg move into a discussion of a new case with the help of special guest Becki Daher. Richard Ramirez, the Night Stalker, terrorized California in the mid-1980's before he has caught with the help of fingerprints and new AFIS technology. Becki Daher was working for the Orange County Sheriff's Office at the time and lifted the fingerprint from the car window that eventually led to his arrest. Join us in a discussion of Ramirez's crimes, the terror felt by the residents of California, and the high-tech and low-tech techniques that led to his arrest and conviction.

Eric Ray and Glenn Langenburg wrap up the final episode in their series on Making a Murderer Season 2 with all of the craziness that didn't fit in all the previous episodes. Doesn't the bloodstain shape mean that he's innocent? Or mean that he's guilty? What about the lack of fingerprints? The burn barrel? The carpet cleaner? The bullet wax? Is Teresa even dead? Is the Double Loop Podcast just another part of the grand conspiracy by the government against Steven Avery? The answer to almost all of those questions is "no", but listen anyway as we close out this case. (This episode is sponsored by IDEMIA.)

Eric Ray and Glenn Langenburg start to wrap up this second season of Making a Murderer with a discussion of the other new suspects in the case, a bit of internet drama, and the vast Wisconsin conspiracy. They then finally move into the discussion of Brendan Dassey and his ongoing appeals process, and how difficult it is for federal courts to review state court decisions.

Glenn Langenburg and Eric Ray spend this episode talking about even more of the forensic evidence from the second season of Making a Murderer. They start with a review of the DNA evidence from the hood latch and the bullet fragment. Can there be too much DNA? They also discuss the trace analysis of the bullet fragment, the lack of fingerprints, the mysteries of brain fingerprinting, and even more of the evidence in the Steven Avery case.
