One thing the Nancy Guthrie case has shown us is that for every qualified investigator diligently following leads, there at least two more armchair detectives trying to solve a crime from the comfort of their homes.
It's been more than 70 days since the mother of Today Show host Savannah Guthrie mysteriously vanished from her Tucson, Arizona home. Since day one, ordinary people around the world have been coming up with their own elaborate theories on who could be responsible, and why.
While the Guthrie case is unique in many ways, it's just one of hundreds of thousands that have remained unsolved long after the deed was done. Someone asked, "What's the one whodunnit mystery that hasn't been solved yet?" and the list read like a must-watch true crime catalogue. From Madeleine McCann, JonBenét Ramsey and of course, Nancy Guthrie, to much older cases like Jack the Ripper, people shared the mysteries that haunt them to this day.
