Who is Mr X? How a true crime podcast helped identify a 1975 murder victim

Brad Willis' MurderETC helped uncover the identity of Oscar James Nedd, who was killed in South Carolina

As the producer of a true crime podcast mainly focused on a decades-old double murder, Brad Willis has had plenty of experience with dramatic and compelling storytelling.

But Willis got the chance to be the story himself this week, when a sheriff in South Carolina whose office has been reinvestigating a 1975 killing publicly credited Willis' show with helping deputies finally identify the victim.
