The Maryland attorney general is appealing the new trial granted to Adnan Syed, possibly delaying his retrial for months.
Syed, the subject of the popular podcast "Serial," has been serving a life sentence since 2000 in connection with the death of his ex-girlfriend from high school, Hae Min Lee.
But earlier this year, a judge decided new evidence could be presented in the case, which led to the new trial.
Syed's defense attorney, C. Justin Brown, successfully argued in court a fax sheet accompanying Syed's cellphone records should've been examined in his first trial.
The sheet basically said the records couldn't be trusted to accurately pinpoint Syed's location. It wasn't brought up in his original trial, and the records were used to corroborate the prosecution's version of events.
But now the state says that isn't enough to justify a new trial and even without the cell tower records, the prosecution presented "overwhelming evidence" against him.
Syed's defense is arguing for another witness to testify. The new witness claims she can give Syed an alibi for the time of the murder.
But prosecutors say they have two unidentified people who will testify that the alibi-witness told them she planned on lying to prevent Syed from being convicted in his original trial.
