Sarah Koenig’s hit “Serial” podcast came to a close in December, leaving some listeners dissatisfied, and many with unanswered questions. But the investigation into Adnan Syed’s story is far from over.

A second podcast, “Undisclosed: The State v. Adnan Syed,” will dive even deeper into the case from “an investigatory perspective instead of a narrative one,” according to the official website. Koenig’s original true-crime podcast, which quickly ensnared listeners from around the world, investigated the 1999 murder of Baltimore teenager Hae Min Lee and investigated Lee’s ex-boyfriend Syed’s conviction of first-degree murder.

“Undisclosed” is sponsored by the Adnan Syed Legal Trust, a group behind the defense of Syed that has raised $93,000 via the crowdfunding website Launch Good, as well as attorneys Rabia Chaudry, Susan Simpson and Colin Miller. Koenig, however, has no involvement in “Undisclosed.”

Syed’s longtime friend, Chaudry initially reached out to Koenig and “This American Life” producers to look into the case that spawned the podcast. “[‘Serial’] further confirmed my perspective on the case that there was a lot of stuff that was done improperly by investigators and by the prosecution and that there’s even more reasonable doubt than there was 15 years ago,” Chaudry told HuffPost Live in December.

Granted the opportunity in February, Syed presented his appeal to the Maryland court in March. The new podcast will debut episodes every two weeks, beginning April 13. The second season of “Serial” will focus on a different case.
