The Watkins File

The morning of Sept. 14, 2017, Tim Watkins rode his mountain bike up Mt. Herman west of Palmer Lake, just like he had done countless times before. But he never returned, and three days later, a crew of volunteer searchers found his body shot and buried on a hillside near one of his favorite trails. His belongings — a shoe, his bike and the contents of his wallet — were found strewn across the mountain. And two years later, no arrests have been made and no suspects have been named. Colorado Cold Case returns for its third season, examining the unsolved killing of Palmer Lake mountain biker Tim Watkins.

Anyone with information about the death of Tim Watkins can submit an anonymous tip by calling the El Paso County Sheriff's Office at 719-520-6666, or by calling Pikes Peak Crime Stoppers at 634-7867.
