Adnan Syed was convicted in 2000 of killing Hae Min Lee, his high-school sweetheart. He was 17 at the time.

Syed’s story was widely publicized in the 2014 “Serial” podcast, which cast doubt on his guilt and inspired armchair investigators to unearth new information.

A lower-court judge vacated Syed’s conviction in 2016. Prosecutors appealed to Maryland’s intermediate appeals court, which in March granted a new trial.
