Righting wrongs: How Joyce Watkins was exonerated in court

In 1988 Joyce Watkins and her boyfriend, Charlie Dunn, were wrongfully convicted of a terrible crime: the murder of Watkins' four-year-old great-niece, Brandi.

Watkins said, "It took everything away from us. It took us from our families, him from his kids. Took us from everything we worked for."

Dunn died in prison in 2015. But last December, in a Nashville, Tennessee courtroom, the 74-year old Watkins finally heard from the Davidson County District Attorney General Glenn Funk the words she had prayed for: "I want to say to both Ms. Watkins, and to the family of Charlie Dunn, that I believe they were actually innocent."
