Adnan Syed, the subject of the popular podcast "Serial," has had his murder conviction reinstated by a Maryland court. Syed was originally convicted of the 1999 murder of his ex-girlfriend Hae Min Lee, but his case gained national attention after it was explored in detail by the podcast. In 2016, a judge vacated Syed's conviction and granted him a new trial, but that decision was overturned by the Maryland Court of Appeals on Monday. The court ruled that Syed's legal team failed to prove that his original attorney's failure to contact an alibi witness affected the outcome of the trial.
