George Knapp welcomed researcher and author David Paulides, who provided an update on his investigation into mysterious disappearances and detailed how his latest research now takes him to urban areas, where he is finding evidence that fits his criteria for this unsettling phenomenon. While he had previously been focused on disappearances in national parks, Paulides explained that he began looking into strange urban cases after reading about a cluster of extremely smart and athletic young men who disappeared and their bodies were later discovered under unusual circumstances. As he began looking deeper into such cases, Paulides was astonished to find that the minutiae of these events had a number of eerie similarities to the national park disappearances he had chronicled in his Missing 411 series of books.
