Mark Hopkinson (Part 1): Killer by Proxy

In Part 1 of our two-part deep dive into the Hopkinson case, we trace the origins of one of Wyoming’s most shocking criminal sagas. Beginning in the quiet, rural Bridger Valley—where authority flows through family networks and reputation—we follow the early life of Mark Hopkinson, a charismatic local favorite whose charm masked a growing pattern of manipulation, violence, and unchecked entitlement.

What starts as a simple water-and-sewer dispute soon spirals into intimidation, threats, and the deadly bombing that kills attorney Vincent Vehar and his family. At the same time, investigators uncover another hidden crime: the murder of 15-year-old Kellie Wyckhuyse, buried beneath a web of lies crafted by Mark and his inner circle.

As alliances fracture and witnesses begin to crack, federal authorities reopen a forgotten bomb plot that pulls the entire valley into a larger investigation. Part 1 ends with Mark behind bars—but far from powerless—as he begins orchestrating a new series of events from inside a California penitentiary.

This episode sets the stage for a devastating second half, where loyalty collapses, secrets surface, and Mark’s reach proves more dangerous than anyone imagined.
