Unsolved Mysteries has earned its cult-classic status for true crime aficionados. The show has covered some of the most famous unsolved cases in history, including D. B. Cooper, The Pizza Parlor Killer, and Polly Klaas, to name only a few.

While the show has entertained millions, its main objective was always to solve cases that seemed unsolvable, and the show was quite successful in doing so. Unsolved Mysteries covered more than a thousand cases and claims to have helped solve over half of those. This success rate just goes to show that the average person's observational powers are more useful than they seem on the surface.

Below are some of the most famous cases that were solved with the help of television viewers after being featured on Unsolved Mysteries.
