Since 1987, “Unsolved Mysteries” has brought attention to missing persons cases, murder cases and even legends that otherwise may have been forgotten.

The original series aired on NBC and was narrated by late American actor Robert Stack from 1987 to 2002. His deep voice and trench coat were staples during his tenure on the mystery series.

The show ran until 2010 and was revived by Netflix in 2020. The streaming service dropped 12 new episodes during its first reboot season.

In recreating the show, producers hoped to highlight cold cases that could lead to new tips or leads.

“Fusing signature elements from the original series with contemporary immersive, character-driven storytelling, the new episodes offer clues and theories with the hope that one viewer holds the key to solving the mystery,” Netflix posted in June 2020 teasing new episodes.

How many cases have been solved due to ‘Unsolved Mysteries?’

Just one day after the Netflix reboot was released in 2020, producers received what they deemed 20 credible tips.

Executive producer Terry Dunn Meurer told USA TODAY in 2020 that the original mystery series helped solve over 260 cases thanks to tips and new tools like DNA testing.

Producers passed the tips to authorities, Meurer said.

As of May 2023, one case has been solved thanks to the rebooted series: the story of Kayla Unbehaun.
