On Oct. 24, 1978, Ethel Louise Atwell of Newark, New Jersey, went to work on Staten Island and never returned home. Workers heard the 46-year-old scream from the parking lot. By the time police arrived, Ethel had disappeared. In August 1978, only two months before Ethel's disappearance, another nurse was found buried in a shallow grave not far from where Ethel parked her car. Several children also disappeared from Staten Island in the 1970s and 1980s. Could Ethel's disappearance be linked to these other cases? Investigative reporter Kristin Thorne returns to the woods with Ethel's family in search of hidden clues in this terrifying cold case.
