The Zodiac case remains one of the most notorious unsolved murder mysteries in American history, and it continues to capture public interest and speculation. The self-proclaimed Zodiac killer was a serial killer who operated in Northern California, primarily in the late 1960s and early 1970s. In 2014 a man named Gary L. Stewart published a book, co-written by journalist Susan Mustafa, The Most Dangerous Animal of All, about how he came to the conclusion that his biological father was the Zodi...
On this episode I spoke with Det. Zack Kowalske, an expert in bloodstain pattern analysis, crime scene reconstruction, and a pioneer in Space Forensics! We discussed BPA (bloodstain pattern analysis), some concerns in the field (error rates), and Zack's research on bloodstain pattern analysis in microgravity.Support the Show!Become a subscriber: https://www.buzzsprout.com/1936265/supporters/newMake a one-time contribution (uses Paypal): Buy Me a CoffeeGet Zack's new book: "Gaming the Reaper: ...
"The role of a forensic science defence expert is often referred to by those working for the police/state/government forensic labs as being on the "dark side."In Joining the Dark Side, author David Schudel outlines the evolution of a fascinating career that starts out in the dark side and looks at what problems can appear in forensic cases. The book delves into the problems inherent to forensic science, in particular cognitive bias and scientific philosophy. It also looks at the emotional imp...
In this episode I spoke with Dr. Itiel Dror, a cognitive neuroscientist known in the forensic realm for his contributions to revealing the unconscious implicit biases in forensic decisions and providing tools to minimize them. He recently published several papers examining - for the first time - cognitive bias in forensic pathology. The Maryland Attorney General has announced an independent audit of in-custody death determinations made by the OCME during the tenure of Dr. David Fowler. Dr. Fo...
Massively Parallel Sequencing has revolutionized laboratories' ability to harness more and more information from our genetics. This has led to massive improvements in medical diagnostics, public health (think SARs-CoV-2 variant identification), ancestry determinations, and now forensic science has begun adapting this technology to criminal investigations.In this episode I speak with Professor Megan Foley, Teresa Snyder-Leiby, and Sarah Copeland about the challenges laboratories are facing as ...
Epigenetics: The clothes of your DNA. While the DNA sequence contains the instructions, your epigenome controls which part of the instructions are read and used. But how do we use this in forensic science? Learn more about biomarkers linked to smoking, age predication, differentiating between identical twins, narrowing the suspect pool, generating investigative leads, and more.Athina Vidaki, PhD, with Erasmus Medical Center in Rotterdam Netherlands, is a professor of Applied Epigenomics. Her ...
New Technology is great...but let's use it to catch the right person. In this episode I spoke with Professors Dr. Matthias Wienroth and Dr. Carol McCartney, two of the authors of "Ethics as Lived Practice. Anticipatory Capacity and Ethical Decision-Making in Forensic Genetics". It's a fascinating discussion about forensic genetics and the rapidly evolving technologies from the perspective of a social scientist and law professor.Read the full text article: Ethics as Lived Practice. Antic...
DNA as the "Biological Witness". Forensic DNA Phenotyping predicts the externally visible characteristics - i.e. what a person may look like - from their biological material. It has applications in criminal investigations when other leads have failed, missing persons identification, and anthropological research.

This week's discussion is all about consent and ethical use of genetic information, including DNA databases. I define and discuss what is meant by consent and informed consent and how it's related to the treatment of Henrietta Lacks and how her story triggered the development of ethical practices in medical science. What are the responsibilities of the forensic geneticist? The law enforcement investigator? What should you think about before volunteering a DNA sample...It's a big topic, and th...
This episode is the first in a series (non-sequential) providing overviews of different fields of forensic science.Meredith Dekalb Miller is an FBI trained expert in Forensic Document Examination with almost twenty years experience in both criminal and civil matters. Her work revolves around determining the authenticity and sometimes reconstruction of documents.To get in touch with our guest: https://dekalbmiller.com/To learn more about the host, Angela Tanzillo-Swarts, MBE: https://practical...
Following on from episode 2...this time our discussion focuses on the experiences of David Schudel, PhD as an expert in the UK. He is an expert in Forensic Chemistry, Fire Analysis, and Cell site analysis (to name a few) and over the years has become that guy who catches all the weird cases. Join us as we explore how the forensic scientist fits into the criminal justice system in England and Wales and hear about a few of those extra weird ones...To Learn more about the host:Angela Tanzillo-Sw...
Teaser trailer of episode 3 of Secrets from the Crime Lab. A peak into how the criminal justice system and crime laboratories intersect in England and Wales. Dr. Schudel discusses his experiences working as a forensic expert for both the prosecution and the defence conducting a wide variety of forensic analyses including forensic chemistry and cell site analysis.

What happens when the crime laboratory gets it wrong? In this episode we discuss the issues with relying solely on laboratory accreditation to determine if a forensic science laboratory is doing the testing correctly, what happens when a lab fails as it did in Washington, D.C., and how other laboratories manage to recover and regain customer confidence. We explore how organizations like the Texas Forensic Science Commission work to ensure quality forensic science work by taking action and the...
Ensuring the validity of the crime laboratory’s test result is paramount. Ensuring that the lab is impartial, competent, and committed to confidentiality is an integral part of that assurance.PLAN - DO - CHECK - ACTLaboratory Accreditation demonstrates conformance with international standards, giving the customer of a crime laboratory confidence in the test results.In this episode we explore the ISO/IEC standards specific to forensic testing and calibration laboratories. These standards apply...
