This second episode of the Case Studies season of Just Science Podcast features Tim Fayle, the Training Capability Lead for IDEMIA Australasia and Chair of the International Association for Identification’s Latent Print Certification Board, for a conversation about the usefulness as evidence of friction ridge detail that has been inadvertently captured in photographs.
In this episode of Just Science Podcast, host Mikalaa Martin welcomes guest, Tim Fayle to discuss several methods and techniques that latent print examiners can add to their toolkit to analyze and compare inadvertently photographed friction ridge detail in order to contribute to the identification of perpetrators. Tim Fayle highlights how the increasing use of social media has led to more inadvertently captured and digital evidence consisting of ridge detail. He also relates several experiences in which he relied on this evidence type’s potential use as a way of resolving difficult or cold cases. He explains several nontraditional ways to scale or recalibrate an image, including using objects with a known size that are located on or very close to the same plane as the ridge detail.
