Netflix released the video on Thursday through a social media puzzle, tweeting: “Let’s see how sharp @Unsolved season 1 made your detective skills...”
Along with the message is an image with the words “The trailer for volume two of Unsolved Mysteries can be viewed at”, followed by a url for the video.
The clip does not reveal full details of the six cases featured in the new season, but teases them with the following key words: “tsunami spirits”, “stolen kids”, “lady in the lake”, “Washington insider murder”, “a death in Oslo”, and “death row fugitive”.
“Why is it important to find out why a person died nearly 25 years ago?” one person wonders out loud in the trailer. “People die all the time. Well, I think her family deserves to know what happened to her.”
Unsolved Mysteries, originally a television show in the US, has been rebooted by Netflix, which unveiled the first six episodes on 1 July.
The show focuses on cold cases and unexplained phenomena. Viewers who believe they have useful information can submit tips online at: unsolved.com/tips.
