“Web of Death,” a six-episode docu-series, follows the investigations of online sleuths as they use digital footprints, DNA databases and the power of social media to solve gruesome, mysterious and bizarre murder cases.

Each episode chronicles a new investigation, focusing on one amateur detective and one case ― from identifying a skull found inside a bucket of cement at a truck stop to a Jane Doe in a California orchard to tracking down a lottery winner who suddenly disappeared to more personal tragedies like a father’s search for his teenage daughter’s shooter. The program highlights the incredible persistence, attention to detail and vast networks that help these web sleuths find answers others could not.
