YOUNGSTOWN — Deputies Friday arrested the man who claimed he acted in self defense when he shot and killed his wife’s lover and critically injured his wife in what he said was an accident.

Deputies were called to the home of Michael and Susan McCoy on Rhonda Road early Wednesday morning after Michael McCoy called 911 to report that he had shot his wife and David Walker after he learned she had been having an affair with Walker, who was shot multiple times and pronounced dead at the scene.

Susan McCoy, 37, was taken to a hospital for treatment. She was in “guarded condition” Friday, according to the Bay County Sheriff’s Office.

Michael McCoy told investigators following the shooting that he initially armed himself with the intention of taking his own life, but his wife talked him out of it. He said he demanded Walker — who apparently had been staying with the couple since he was released from the Bay County Jail on Sunday following a domestic battery arrest — leave their home. The two men began to argue before he shot Walker.

Because there were no other witnesses to the shooting, which occurred around 2:30 a.m. in the front yard of the McCoys’ home, investigators were waiting for Susan McCoy to recover to the point where they could take her statement. Whether he was charged or not would depend on whether her version of the shooting confirmed what Michael McCoy said.

Investigators spoke with Susan McCoy Friday. BCSO officials didn’t release any details from her statement, and they didn’t return a call for comment Friday, but Michael McCoy was arrested shortly afterwards. He is charged with an open count of murder and attempted murder. He was taken to the Bay County Jail to await his first court appearance Saturday.
