Washington DC's up-and-coming Bloomingdale neighborhood remains gripped by fear three weeks after the murder there of Democratic National Committee staffer Seth Rich — with still no reported leads, suspects or arrests in the killing.

At the same time, conspiracy theories surrounding the murder have reached a new frenzy, especially after the hacking of DNC e-mails led to the resignation of its chairwoman, Debbie Wasserman Schultz.

Rich was beaten, shot and killed early on the morning of July 8 while he was walking home and talking on the phone to his girlfriend. Police have said they haven't determined if his murder was a botched robbery or something else. The killer or killers appear to have taken nothing from their victim, leaving behind his wallet, watch and phone.
