Eric Ray and Glenn Langenburg focus their forensic science backgrounds on the infamous Kathleen Peterson murder as it was portrayed in The Staircase. The guys review their initial impressions of the case and the documentary and then tell the basic outlines of the story where Michael Peterson is suspected, arrested, charged, and convicted of the murder of his wife. There are so many twists and turns to this story that we had to get them all out of the way in this episode before focusing on the forensics in upcoming episodes.

Glenn Langenburg and Eric Ray return to the annual IAI conference in San Antonio to talk to attendees about the interesting lectures and workshops that they've seen this year. Morgan Hays from Florida talks about how he stays current with the field as a supervisor and how the exclusion and verification topics were covered at the conference. Do you trust your verifier? Linda Manigault from Nevada then joins the conversation and discusses the workshops on FRStat and statistical models that she attended. Glenn ends the episode with a BIG announcement!

Glenn Langenburg and Eric Ray wrap up the three-part discussion on the AAAS Report on the Quality and Gap Analysis of Latent Fingerprint Examination. Surprisingly, the guys agree with many of the recommendations and conclusions in the document with an occasional quibble or clarification. As was hinted in the past two episodes, there are more serious concerns with the report's suggested language and proposed limitation of the word "identification".

Glenn Langenburg and Eric Ray continue the discussion on the pros and cons of the AAAS report. Carey participated with the review of the report and discusses the positive recommendations and the limitations that come from the report not being published in a traditional peer-reviewed journal. After that discussion wrapped up, Carey, Eric, and Glenn get a little off-topic and talk about attending AFIS Users' Conferences. Carey and Glenn presented at the most recent Idemia conference on the benefits of the Case AFIS system. Eric talks about a local AFIS conference and user discussions on how data analysis can lead to improved search practices.

Glenn Langenburg and Eric Ray finally get around to discussing the report on latent fingerprint comparisons from the American Association for the Advancement of Science. John Black (from Black and White Forensics) was on the committee that wrote the report and joins the discussion on some of the merits and limitations of the paper. While many of the research recommendations are the next steps that the latent print field needs, they are also the same recommendations made by other reports. One of the report's main failures is the suggested wording for the identification decision.

Glenn Langenburg and Eric Ray are joined by Della Wilkinson from Canada to discuss the final resolution of the Bornyk case from British Columbia. Originally, Judge Funt (see Double Loop Podcast episdoe 10) ruled that the fingerprint evidence would not be admitted after conducting his own study of latent prints and his own comparison. The Crown appealed and a new trial began with the original examiner, the verifier, Della, and Simon Cole. This episode the Double Loop Podcast also pays tribute to Tony Cantu. He will be missed.

Eric Ray sits down for an interview with Simon Cole from the University of California Irvine. Simon explains how he first became interested in forensics and in latent print comparisons in general, and then outlines the history of his criticisms of the field. Glenn Langenburg later joins Eric for a review of the interview and some of Glenn's perspectives on how Simon's criticisms and the latent print response have both evolved over time.

Glenn Langenburg and Eric Ray continue their interview with Matt Marvin from Ron Smith and Associates about the erroneous identifications and eventual exoneration of Beniah Alton Dandridge. This video (available on YouTube via RayForensics.com) goes through an in-depth and technical review of the latent prints, the errors, the exclusions to Dandridge, and the eventual identifications to the victim's son (who discovered the body).

Eric Ray hosts a live Double Loop Podcast discussion at the 2017 Florida Division IAI Conference in Panama City Beach, FL, and Glenn Langenburg joins via phone for the discussion. The audience hit Eric and Glenn with a variety of questions and the conversation swings from AFIS automation to using AFIS as a support for an identification decision. From the requirements that Florida courts put on latent print examiners to how to keep improving yourself so that you can make that jump into a career in forensics.

Eric Ray and Glenn Langenburg are joined by Matt Marvin of Ron Smith and Associates to discuss in greater detail the details of the Beniah Dandridge case. Matt discusses how he and RSA got involved in the case, the history of the Manning murder, the original investigation, the Dandridge trial, his appeals, RSA's involvement, and Dandridge's eventual release. Check back to RayForensics.com soon for a YouTube video detailing the comparisons in this case.
