New documentary about Adnan Syed from the "Serial" podcast

This spring, HBO will air a new documentary about Adnan Syed, the subject of the first season of the Serial podcast. The four-part series is directed by Amy Berg ("Deliver Us from Evil"). From the Baltimore Sun:

Syed, the subject of the wildly popular "Serial" podcast, was convicted in 2000 of killing his former girlfriend and Woodlawn High School classmate. But "Serial" raised questions about why his attorney, M. Cristina Gutierrez, did not call a potential alibi witness. The attorney died in 2004.

Syed's conviction was vacated in June 2016 by a Baltimore circuit judge, and the Court of Special Appeals upheld the decision, prompting the state to bring its case for reinstating the conviction before Maryland's highest court in November.

The HBO trailer prominently features Syed's family friend, Rabia Chaudry, who brought the case to "Serial" host and former Baltimore Sun reporter Sarah Koenig. The documentary, directed by Academy Award nominee Amy Berg, promises "a piece of evidence that nobody even realized existed for all these years."

It's unclear when the Court of Appeals, Maryland's highest court, will make a decision. Chaudry said in November that Syed's family expects a ruling by August.
