“48 Hours” investigates case of Florida man missing since 2000

The mystery behind a missing Florida man was finally solved after nearly two decades. Mike Williams disappeared while on a hunting trip in 2000. His wife, Denise, led a massive search for him. Then community members concluded an alligator had killed him. But in December 2017, new conflicting information emerged that changed everything. “48 Hours” correspondent Richard Schlesinger joins “CBS This Morning” to preview his report for Saturday.
