Sneak peek: The Mansion Above Dale Hollow Lake

A California couple bought a mansion near Dale Hollow Lake, straddling the Kentucky-Tennessee border, which locals believed to be cursed. In September 2022, the husband, Mike Harding, vanished without a trace. His wife, Julie Harding, a captain with the California Highway Patrol, urgently contacted authorities but received little information. She traveled to Tennessee personally and became frustrated with the lack of updates from Sheriff Brandon Boone's office in Clay County, Tennessee. The case has since uncovered a murder plot; investigators found clues leading to Mike's killer. "48 Hours" correspondent Peter Van Sant will report on this story Saturday, Oct. 24 at 10/9c on CBS and streaming on Paramount+.
