In March 2003, a man robbed a Tulsa, Oklahoma convenience store at gunpoint. The clerk of the store provided an initial description of the robber. When shown a six person photo line-up, the clerk identified Marrio Willis as the robber, even though Willis did not match the initial description. Although Willis’s lawyer believed the real criminal to be Antonio Ellis, who more closely resembled the description, he failed to follow the procedure required to show the clerk Ellis’s picture or pursue this defense. In December 2003, a jury convicted Willis of armed robbery, and he was sentenced to 10 years. At an evidentiary hearing in April 2006, the clerk, who by then had been shown a photo of Ellis, testified that Ellis was the real culprit. Willis’s conviction was vacated, and he was granted a new trial by the Oklahoma Court of Criminal Appeals. The prosecution dismissed the charges later that month.
