IRONTON, Ohio (WSAZ)--An Ironton man granted a new trial following his murder conviction has now pleaded guilty to a lesser charge.

Police say that in the July 2005, William Cooper went into a home in Lawrence County, Ohio and shot two men. Scott Marcum died, and Orlan Harper Jr. was wounded.

Later that year, A jury found Cooper guilty of murder and felonious assault.

The Ohio District Court of Appeals recently ruled the state did present substantial evidence, but the jury instructions in the case were not complete. As a result, they overturned the conviction and ordered a new trial.

Yesterday, Copper pleaded guilty to voluntary manslaughter and was sentenced to 13 year in prison. Cooper will have to serve at least 10 before he can be released.
