A murder in the small southern town of Adel, Georgia, sent Devonia Inman to jail 20 years ago. He was accused of robbing and shooting a woman named Donna Brown in a Taco Bell parking lot. He swore he was innocent and there were good reasons to believe him. And while he awaited trial, three more brutal killings took place in Adel. Did police get the wrong man?

Devonia Inman goes on trial for his life. But there’s really no evidence against him. Witnesses keep changing their stories. And the jury never hears about an alternate suspect — a man who was just arrested for a brazen murder of two prominent community members.

Shaliesh Patel was visiting Adel when he was brutally murdered in the spring of 2000. Years later, his family still doesn’t know anything about who killed him. Their interactions with the Georgia Bureau of Investigations left them with more questions than answers. But one thing was clear: Patel’s murder was part of an emerging pattern of crime.

William Carroll Bennett and Rebecca Browning were beloved in Adel. There was no reason anybody would want to hurt them. Then they were savagely beaten in broad daylight at a popular lunch spot. Thanks to the actions of a couple of customers, their assailant was quickly apprehended: 20-year-old Hercules Brown. But the question quickly arose, was this the only murder Hercules was responsible for?

Hercules Brown grew up in a well-respected family in Adel. Residents remember him as a good kid. But then something changed. He became violent and mean. And he had several run-ins with the law. But when he got in trouble, nothing seemed to stick. Until the murders of Bennett and Browning raised new questions about the Taco Bell and the Patel murders too. When DNA comes back as a match to Hercules on a key piece of evidence, will it be enough to help Devonia Inman?

Jessica Cino is a dean at the Georgia State University law school — and Devonia Inman’s biggest advocate. His plight has shaken her faith in the criminal justice system. She’s poured hours into his case, trying to help him clear his name. But the odds are stacked against him, and she knows it. But then new evidence comes to light, something the cops should have known about all along.

After the new evidence comes to light, we look back at the investigation into the murder of Donna Brown. And share some information we didn’t quite know what to do with. Information about some key players who we know shaped the outcome of this case. Players we still have questions about. One is an elusive police detective with a bad reputation. The other is a witness we’ve talked about before. Or maybe she’s a suspect. It’s hard to tell.
