As a park ranger with the National Park Service's law enforcement team, Andrea Lankford led search and rescue missions in some of the most beautiful (and dangerous) landscapes across America, from Yosemite to the Grand Canyon. But though she had the support of the agency, Andrea grew frustrated with the service's bureaucratic idiosyncrasies, and left the force after twelve years.

These are the stories that defy conventional logic. The proverbial vanished without a trace incidences, which happen a lot more (and a lot closer to your backyard) than almost anyone thinks. These are the missing whose situations are the hardest on loved ones left behind. The cases that are an embarrassment for park superintendents, rangers, and law enforcement charged with Search & Rescue.

As oil-boom money poured into Anchorage, Alaska the city quickly became a prime destination for the seedier elements of society: prostitutes, pimps, con men, and criminals of all breeds looking to cash in. However, something even worse lurked in their midst. To all who knew him, Robert Hansen was a typical hardworking businessman, husband, and father. But hidden beneath the veneer of mild respectability was a monster whose depraved appetites could not be sated. From 1971 to 1983, Hansen was a human predator, stalking women on the edges of Anchorage society.

I order another bourbon, neat. This is the drink that will flip the switch. I don’t even know how I got here, to this place, to this point. Something is happening to me lately. I’m drinking too much. My sheets are soaking wet when I wake up from nightmares of decaying corpses. I order another drink and swig it, trying to forget about the latest case I can’t shake. Crime solving for me is more complex than the challenge of the hunt, or the process of piecing together a scientific puzzle. The thought of good people suffering drives me to the point of obsession.

On May 31, 2014, in the Milwaukee suburb of Waukesha, Wisconsin, two 12-year-old girls attempted to stab their classmate to death. Morgan Geyser and Anissa Weier’s violence was extreme, but what seemed even more frightening was that they committed their crime under the influence of a figure born by the internet: the so-called “Slenderman”. Yet the even more urgent aspect of the story, that the children involved suffered from undiagnosed mental illnesses, often went overlooked in coverage of the case.

Hundreds have disappeared. So many that we've lost count. Once Search and Rescue teams pull out and the news cameras switch off, the spotlight on these individuals dim and the cases turn cold.

It’s a chilling reality that homicide investigators know all too well: The last face most murder victims see is not that of a stranger, but of someone familiar. Whether only an acquaintance or a trusted intimate, such killers share a common trait that triggers the downward spiral toward death for someone close to them: They are masters at hiding who they really are.
