In most missing person cases, there is at least some sort of trail investigators can follow. But when 32-year-old Chelsea Grimm’s Ford Escape was found abandoned near the rural town of Ash Fork, Arizona, while en route to Connecticut, she vanished without a trace. Over half a year later, investigators have no leads, only vague sightings, potential tips, and many possible outcomes. Was she stalked while making her way across the country, had a mental break after her car broke down, or did she join a self-help cult and wanted to leave her old life behind in California? Is Chelsea Grimm still out there, and does she want to be found?
