Parker and three others -- Alphonso Cave, John Earl Bush, and Terry Wayne Johnson -- were charged with robbery, kidnapping, and murder in the death of Frances Julia Slater in Martin County in April 1982. Each was tried separately. Parker, Cave, and Bush were sentenced to death, and Johnson to life in prison. In the trials of Parker, Cave, and Bush the state argued inconsistent positions that each of these men was the one who actually shot Slater. Parker later discovered undisclosed information about an incident involving Cave battering his prison cellmate. The cellmate told authorities that Cave confessed that he (Cave) was the one who actually shot Slater, and that Bush was the one who stabbed her. Parker filed a collateral attack on his death penalty, arguing that the state was required -- but failed -- to disclose this information to him. The trial court agreed and ordered a new sentencing proceeding. The State appeals.
