When Mark Knapp’s routine commute home from work one February night in 1984 ended with his car abandoned and his body at the bottom of an old marble quarry, the shock rippled far beyond one family.

What followed was not a straight line from crime to justice. Suspects were quickly identified and charged in connection with Mark’s death, but shifting narratives and fragile witnesses fractured the entire foundation of the case just as the truth came into view.

Cam Lyman vanished in the summer of 1987, leaving behind a forty-acre estate, dozens of prizewinning dogs, and a silence that would stretch on for more than a decade.

Friends and family disagreed on whether Cam had walked away or been taken or worse. Meanwhile, millions of dollars in trusts and assets seemed to evaporate. When Cam was finally found, hidden beneath the very ground no one had searched, the mystery didn’t end. It compounded.

While police spoke in hints about suspects, the only charge ever filed had nothing to do with murder. In this case, every lead seems to circle back to the same question: if you follow the money, will it reveal what happened to Cam, or just uncover another carefully buried secret?
