Derrick Jamison, 33 years ago in the state of Ohio, was convicted for a murder he did not commit and sentenced to die by execution. He spent nearly all of his subsequent 20 years in prison on Death Row, where he faced six execution dates -- including one occasion when he came within 90 minutes of execution by lethal injection. Later it was shown that Jamison did not fit the eyewitness descriptions of the men who committed the murder and that police withheld evidence from a key witness who’d identified two other men as the perpetrators. He was released from prison in 2005 and has spent the years since then educating people about the risks of wrongful conviction.
