Serial: Who killed Hae Min Lee?

Hae Min Lee was a high school senior in Baltimore, Maryland, who disappeared on January 13, 1999. When her body was found a month later on February 9, an investigation ensued that relied heavily on information provided by Jay Wilds, a marijuana dealer who had graduated from Hae's high school. The police claimed to have focused on Hae's ex-boyfriend, Adnan Syed, following a tip from an anonymous caller and information provided by Jenn (a friend of Jay but not of Adnan). After Adnan’s conviction, the case was featured in the podcasts Serial and Undisclosed, and some of the new evidence and arguments led the court to overturn Adnan's conviction and grant him a new trial. Followers of the case have made maps containing significant locations, multiple possible timelines have been suggested, and debates have ensued on forums such as Reddit.
