On a quiet summer night in 1999, a 48-year-old man disappeared after what appeared to be a normal night out with friends in the sleepy town of Idaho Falls, Idaho. Darwin Vest, known to many as “spiderman” thanks to his unparalleled knowledge of spiders, left a local bar around 1 a.m. on June 3, 1999 — then seemingly vanished into thin air. For more than two decades, his case has haunted the residents of Idaho Falls as theories surrounding his case range from a tragic fall into the nearby river to something far more sinister.
