One can argue that the genesis of the current "true crime documentary" craze is the NPR podcast, "Serial," which reexamined the case of Adnan Syed, convicted of murdering ex-girlfriend Hae Min Lee.
A trailer for the new HBO documentary on the case teases new evidence. The cable network is set to air the four-part documentary, “The Case Against Adnan Syed,” this spring.
You'll recall that Syed was granted a new trial following the podcast.
The trailer says the new documentary will include "a piece of evidence that nobody even realized existed for all these years."
