State of Ohio v. Keenan (2013-Ohio-4029)

On September 24, 1988, a jogger found the body of 19-year-old Estel Anthony Klann in Doan’s Creek in Cleveland, Ohio. Klann had been stabbed three times in the chest and his throat had been cut. Three men were charged with the murder: Thomas Michael Keenan, Joseph D’Ambrosio and Edward Espinoza. Espinoza pleaded guilty to manslaughter and testified against Keenan and D’Ambrosio, who were tried separately. In return, Espinoza was sentenced to 15 to 75 years in prison.Both men were sentenced to die, but a federal judge overturned D'Ambrosio's conviction in 2006. She ruled that several pieces of evidence that could have exonerated D'Ambrosio were improperly withheld by prosecutors.Keenan, who goes by Michael, claims that same evidence was withheld from him and his lawyers. D'Ambrosio and Keenan were tried separately, but their cases were essentially the same. The same questionable evidence that convicted D'Ambrosio was used to convict Keenan.
