Sarah Koenig sorted through thousands of documents, listened to trial testimony and police interrogations, and talked to everyone she could find who remembered what happened between Adnan Syed and Hae Min Lee. She discovered that the trial covered up a far more complicated story than the jury – or the public – ever got to hear. The high school scene, the shifting statements to police, the prejudices, the sketchy alibis, the scant forensic evidence — all of it leads back to the most basic questions: How can you know a person’s character? How can you tell what they’re capable of? In Season One of Serial, she looks for answers.
