The ending of Serial was extremely frustrating. In the beginning of the final episode, Sarah Koenig stated that by the end of this episode we would have some closure. There was no closure though, only more open ended questions and a new possibilities of who could have killed Hae.
After listening to this series, it worrisome that there could be an innocent man sitting in jail for a murder that he may not have committed. There is a lack of physical evidence against Adnan. Of course Jay’s story might hold some truth but there are huge inconsistencies in both of their stories. Who is lying, and where do the lies start? For example, in the last 15 minutes of Koenig’s final episode she speculates that neither Adnan nor Jay killed Hae. A few days before Hae's murder, a rapist and murderer named Ronald was released from jail. Ronald was arrested later for a murder similar to Hae’s. This speculation could be just that but every lead must be exhausted when the serious possibility exists that a man has been wrongly convicted.
This case is very messy and is built largely on circumstantial evidence. If Adnan is responsible for Hae's murder, he should face justice. If not, he will sit in jail for the rest of his life. At the end of the Serial podcast, another question is raised. How can this be reconciled?
