Tyrone Noling (pictured) is an inmate on Ohio’s death row whose guilt has been called into doubt by a lack of physical evidence, recanting witnesses and refusal by the state to conduct a DNA test. Andrew Cohen, writing in a recent issue of The Atlantic, compared Noling's case to that of Troy Davis, who was executed in Georgia in 2011, despite doubts about his guilt. Noling was convicted of the 1990 murders of an elderly couple in their home. Initially, there was no physical evidence linking him to the crime, and no witnesses against him. When an aggressive investigator took over the case, some witnesses began giving statements against Noling. Cohen reports that all of these witnesses have since recanted their statements, claiming they were pressured by the prosecutor. In 2009, 13 years after the original trial, prosecutors provided defense attorneys with handwritten police notes from the investigations in 1990 in which a witness identified another man as having committed the murders. The state is currently refusing DNA testing of evidence collected from the crime scene that might place this man at the scene of the crime.
