On August 7, 1988, journalist Keith Reinhard disappeared while writing a novel about another man’s disappearance.

He has never been found.



In a town plagued by darkness, two men vanished without a trace under the same bizarre circumstances. The ominous legacy surrounding their strange disappearances has become one of Colorado’s greatest unsolved mysteries.




Tom Young was a veteran of the US Army Special Forces and former school teacher from Silver Plume, Colorado.

He lived alone with his dog on the south side of Pendleton Mountain - the dark side of town that the sun doesn’t touch for almost five months of the year.

Tom owned and operated the Charing Cross Station, a travel bookstore located on Silver Plume’s Main Street.

On September 7, 1987, Young closed up his bookshop, and along with his dog, mysteriously vanished without a trace. He was never seen alive again.

Eleven months after his disappearance, two hunters discovered the remains of Tom and his dog in the mountains outside Silver Plume. Each had died from a bullet wound to the head.

A gun was found on the scene, along with pieces of a shredded green tarp, suggesting that the bodies had been purposely concealed.

The death was eventually ruled a suicide, but a cloud of suspicion remained.



Keith Reinhard was a Daily Herald sportswriter from suburban Chicago. On a three month sabbatical from his job, Keith moved into Tom Young’s vacated bookstore. He soon became obsessed with the mystery surrounding Young’s disappearance and began writing a novel based on Tom’s story.

One week after Tom Young’s remains were found, Keith walked through Silver Plume telling everyone he saw that he was going to climb to the top of Pendleton Mountain. Townspeople found this peculiar as Keith had a known fear of heights, and was leaving at 5 PM - far too late in the day to begin a difficult six-hour hike. That night, Keith Reinhard did not return.

For seven days, over 200 men and a dozen trained dogs combed the mountains searching for Reinhard.

Inside his apartment, investigators discovered Reinhard’s unfinished novel. The final paragraphs in the story read like a description of his own disappearance.

Despite one of the largest search and rescue missions ever launched in Colorado’s history, no trace of Keith Reinhard was ever found.

Keith Reinhard’s daughter, Tiffany, searches for her father in the mountains above Silver Plume, Colorado.

WHAT really happened?

Thirty years later, a series of bizarre speculations, rumors and sinister theories about what actually happened to Keith and Tom have given rise to a story of legend in the old mining town of Silver Plume - a town with a historical legacy of tragedy and death.

Did Keith Reinhard perish on the mountain? Or, is it possible he set up his own disappearance? Did he commit suicide? Was he murdered? Did the disappearance of Tom Young have any relationship to his own?

Working with original case investigators, Dark Side of the Mountain follows the journey of Keith Reinhard’s children, Tiffany and Kai, as they pursue answers to this mountain mystery.

Dark Side of the Mountain is the chilling true story of two mysterious disappearances that blur the line between fact and fiction.
