In July of 2019, 69-year-old Barbara Thomas stepped just few paces ahead of her husband during a short walk in California’s Mojave Desert. In the wide-open landscape, under a blazing summer sun, she should have been visible for miles. But in a matter of moments—she was gone.

Despite massive searches by air and ground, no trace of Barbara has ever been found. Was it the unforgiving desert heat, a sudden medical emergency, an abduction, or something stranger tied to the Mojave’s eerie folklore?

In this episode of Mama, Mysteries & Midnight Murders, Julia Rose explores Barbara’s life, the search that followed, the contradictions in her husband’s account, and the theories that still haunt this case.
