COLUMBUS, Ohio — A federal judge in Ohio is halting the execution of a man who was convicted in the 1984 shootings of his ex-girlfriend and her boyfriend but says he doesn't remember the slayings.

Sixty-three-year-old Daniel Lee Bedford was scheduled to be put to death Tuesday. His attorneys had sought a stay of execution to allow more time for the courts to consider issues they raised. They say Bedford has dementia and a mild mental disability that keep from fully understanding the meaning and purpose of his death sentence

The office of U.S. District Court Judge Algenon L. Marbley said Monday he was granting the request for a stay.

A spokeswoman for the Ohio attorney general's office says prosecutors will appeal to the 6th U.S. Circuit Court of Appeals in Cincinnati.
