Family members both say that Diamond Bynum and King Walker could make anyone smile. Diamond, whose full name is Diamond Daisy Bobbie Monet Bynum, has been described as someone with a “bubbly personality” and an “infectious smile.” Diamond has been diagnosed with Prader-Willi syndrome, a genetic condition with both mental and physical implications.    Mentally, even though Diamond was 21 at the time of her disappearance, Diamond has the capacity of a 5-to7-year-old, and it’s difficult for her to communicate and converse with others. Her family understands her, however, and she knows her father’s phone number. Physically, her condition’s symptoms manifest in short stature, as Diamond is 4’8”. She also has a pronounced limp, misaligned teeth, and Diamond walks with one arm bent. Prader-Willi syndrome also induces a constant feeling of hunger, leading those with the condition to over-eat. Diamond is 238 pounds, and she’s expressed that her favorite food is cheeseburgers.    Diamond also has medication that she takes daily, and when she doesn’t adhere to her medication, Diamond may become a danger to herself.   King Rajan Walker is Diamond’s nephew, and was 2-years-old at the time of his disappearance. Like a typical toddler, his family notes that King loved to run around. His favorite game at the time was to make people chase him as he zipped around.   Saturday, July 25, 2015, was meant to be a day of family bonding.  King was dropped off at Diamond’s family home early that morning so King could spend the day with his grandparents and his aunt while his mom attended a class in Chicago. Around 10:40 am, Suzanne and King both laid down to take a nap. But, when Suzanne woke up around 11:00 am, both King and Diamond were gone. Immediately Suzanne believed that Diamond had taken King for a walk around the block, which wasn’t unusual because Diamond enjoyed taking walks, and did so often with her family while they lived in Hammond. However, even though Diamond often wanted to take care of King alone, and believed she was capable, due to her mental and physical condition, the family says Diamond was never actually unsupervised with King.   In February of 2015, Diamond and her immediate family moved from Hammond, Indiana to the nearby town of Gary. Because she was only in Gary for a few months before disappearing, it’s likely Diamond was incredibly unfamiliar with her new neighborhood.   After Suzanne quickly searched for Diamond and King up and down their street, Suzanne called authorities to report the pair as missing. Investigators responded nearly immediately, and begin piecing together the still-short timeline. Due to Diamond’s physical and mental condition, and considering King’s young age, the two couldn’t have walked more than a few miles, and it would have been difficult for Diamond alone to keep King, a toddler, under control.

Still on July 25th, employees at a local McDonald’s are the first to report a positive sighting of Diamond and King — but the two are seen there before they had been officially reported missing, so the employees had simply given them the food they ordered and didn't take note of where or when they left. The employees were also adamant that Diamond and Walker were there together and that there wasn't anyone else with them.   Four days later, investigators begin a large-scale search of nearby abandoned homes with numerous volunteers. The police employ K9 units, that track both Diamond and King’s scent down the street near a local gas station and train tracks — but ultimately the dogs don’t find anything else. The official law enforcement searches are eventually called off in early August, with a lack of resources being noted as the cause.   In the days and weeks following Diamond and King’s disappearance, some witnesses have come forward with unconfirmed sightings of the pair. Some say they saw both Diamond and King at a bus stop, while others say they saw them at a nearby White Castle and Checkers restaurant. To that end, the restaurant witnesses claim Diamond and King were with an unidentified woman. No more information has been provided about those unconfirmed sightings.

Today, Diamond and King’s disappearances remain unsolved. It took nearly two months before there was a Silver Alert issued for Diamond, and it’s unclear why there was never an Amber Alert issued for both of them, citing King’s age and Diamond’s mental capabilities. Following the one-year anniversary of the case, investigators launched a task force with renewed energy — but nothing noteworthy is made publicly available regarding new leads. Of their investigations, detectives do note that they began looking at local sex offenders, and identified someone of interest, but have not released any more public information. 

One of the more prevalent theories is that Diamond and King got lost and took shelter in an abandoned home waiting to be found, only, unfortunately, to perish due to the environment or unstable and unsafe shelter conditions. Others theorize that someone nefarious — like a sex offender — preyed upon the vulnerable pair.

Lastly, another theory surrounds the belief that Diamond and King are somehow involved with the unidentified woman supposedly seen with them at a few fast food locations. Either the woman simply made sure they were fed and let them on their way, or she took the individuals and started a new life somewhere else. ​​
