37: Diamond Bynum and King Walker

On July 25, 2015, Suzanne King-Jones awoke from a nap to find her stepdaughter, 21-year-old Diamond Bynum, and her grandson, 2-year-old King Walker, missing. It was believed they might have left for a snack, but extensive searches, including in over 15,000 abandoned buildings in Gary, Indiana, yielded no clues. Diamond, who had a mental capacity of a five-year-old due to Prader-Willi syndrome, required constant supervision and was known to wander. The police response to their disappearance was criticized, particularly for not issuing an Amber Alert. Family members conducted their own searches over the following days, igniting further media and public interest.

The case included several unconfirmed sightings of the pair in various locations, but none were substantiated. A person of interest, Terence B. Williams, was identified but later exonerated. The investigation saw no significant progress, and official searches eventually ceased after nine days due to dwindling resources and leads. Over the years, the case has remained unsolved with families holding out hope. The episode closes with descriptions of Diamond and King's physical traits and reminders for anyone with information to contact the police.
