Earley Story will never forget the name Alfredo Shaw.

As a longtime employee at the Shelby County Jail in downtown Memphis, Story had seen the young man come in and out of the detention facility known as 201 Poplar since the 1980s. Shaw acted cocky, but there was fear in his eyes. Story, a devout Christian, occasionally had conversations with him about God.

In 1994, Shaw became a witness in a grisly triple homicide. A local drug dealer, along with his mother and a teenage friend, had been abducted, murdered, and buried in a freshly dug grave at a cemetery in South Memphis. Prosecutors arrested 25-year-old Tony Carruthers, who had recently gotten out of prison. There was nothing directly tying him to the crime — and he swore that he had nothing to do with it. But Shaw claimed that Carruthers confessed to him. In 1996, a jury sentenced Carruthers to die.

Like most people, Story assumed Carruthers was guilty. But in January 1997, Story himself was accused of a crime he swore he did not commit. He was arrested and charged with selling drugs to an undercover officer. There was no evidence against Story — in fact, the presiding judge initially threw out his case for lack of probable cause. But in 1999, he was tried, convicted, and given probation. The main witness against him was Shaw.
