When she was four years old, Shanelle Dawson's mother, Lynette, disappeared. On 8 January 1982, the woman who had been a loving, constant presence vanished without a trace. Four year old's might not be able to articulate questions or understand a lot, but the ache of absence is very real. Year after year that ache persisted. Shanelle's father, Chris Dawson, claimed that his wife just needed to get away. This is what he told Lyn's parents and siblings. This is what he told his daughters. But Lyn never returned home.

Teacher and former rugby league player Chris Dawson appeared to have it all - a loving family and a beautiful home in Sydney's Northern Beaches. But in the summer of 1982 his wife Lynette disappeared and not long afterwards Dawson married a much younger woman, a former student. Less than a decade later this young woman escaped the marriage and went to the police to record her suspicions that Dawson had been involved in Lynette's disappearance. A homicide investigation followed but got nowhere until 1998, when Detective Sergeant Damian Loone was handed Lynette's file.

On February 13, 2017, two Indiana teenagers, Abigail Williams, 13, and Liberty German, 14, went for a walk in the woods near the abandoned Monon High Bridge. They never returned home.

Greg DeVillers was a top biotech executive, and Kristin Rossum was embarking on a career in toxicology at the San Diego Medical Examiner's office.

Authorities deemed it a suicide. Until they discovered that the rare poison found in Greg's body was the same poison missing from Kristin's office.
