Vos PCAST Article

Vos PCAST Article

Eric Ray and Glenn Langenburg discuss last year’s article, Using the PCAST Report to Exclude, Limit, or Minimize Experts by Eric Alexander Vos published in Criminal Justice. We note the extreme bias of the article to exploit the emotions of the judge and jury instead of logic, reason, or data, and we find the serious flaws in many aspects of the paper.

Episode 151 – Theresa Stotesbury Interview

Theresa Stotesbury Interview

Theresa Stotesbury Interview

Glenn Langenburg and Eric Ray follow some good advice from Niki Osborne and interview Dr. Theresa Stotesbury from Trent University in Ontario. Theresa has developed a synthetic blood substitute using sol-gel for use in bloodstain pattern analysis training. We learned a lot and can’t wait to find out more.

“Analyzing complex blood stain patterns can be quite difficult. Especially when you have patterns overlapping and it’s because all the blood looks the same. And what’s even more difficult is to get someone to train someone in disentangling complex blood stain patterns. So how do you tell someone there’s lots of impacts here? How can we start teasing out sequencing and things like that? So our research group thought a lot about disentangling these complex patterns and how we could kind of address that as an issue in training. Well we all bleed the same color so you need the next point in learning. So we created these substitutes where they’re all red in white light and then we’ve added phosphorescent powders into them. They shine UV light on them and it’s just amazing.”

DFSC Stats & NCFS Ends

Eric Ray and Glenn Langenburg get back into the swing of things with big news in the spring of 2017. The Defense Forensic Science Center (Army Crime Lab) just released a statement saying that their reports would now include a likelihood with each latent print identification. Also, the National Commission on Forensic Science (NCFS) was not renewed by the new Department of Justice.

Episode 143 – 2017 IAI Position Statement

2017 IAI Position Statement

2017 IAI Position Statement

Eric Ray and Glenn Langenburg work their way through the newest position statement from the International Association for Identification. Does it allow examiners to say whatever they want? Is it too vague? Does it overstep the IAI’s role, or does it abandon the IAI’s traditional role in the discipline? All good questions that Eric and Glenn will try to answer (sort of).
