In 2015, when the cell phone expert who testified at Adnan Syed’s trial said he no longer stood behind his testimony, she wrote an extensive update in 2019 when Maryland’s highest court reversed a decision to give Adnan a new trial, she covered it. In the years since season one concluded, Sarah Koenig wrote updates about important developments in the case. 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. She discovered that the trial covered up a far more complicated story than the jury – or the public – ever got to hear. 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. Some people believe he’s telling the truth. But Adnan has always maintained he had nothing to do with Hae’s death. The case against him was largely based on the story of one witness, Adnan’s friend Jay, who testified that he helped Adnan bury Hae's body.

Her 17-year-old ex-boyfriend, Adnan Syed, was arrested for the crime, and within a year, he was sentenced to life in prison. A high-school senior named Hae Min Lee disappeared one day after school in 1999, in Baltimore County, Maryland. A month later, her body was found in a city park.
