The Darkest Web: 2. Man with the amazing memory

The podcast investigates the efforts of Homeland Security agents Greg Squire and Pete Manning to identify a 12-year-old abuse victim, named Lucy, whose images are circulating on the dark web. Frustrated by Facebook's refusal to use its facial recognition technology to find a photo of Lucy, the agents turn to more conventional methods, focusing on details within the images, such as a distinctive brick wall. This leads them to John Harp, a brick expert at Acme Brick, who identifies the brick as an Alamo fire brick. Because the brick was only sold within a 100-mile radius of the manufacturing plant, agents draw a circle on the map and narrow their search. Simultaneously, the podcast shares the story of Elisa, a woman in her late 20s, grappling with the abuse she suffered as a child at the hands of her older brother.
