A candidate for attorney general and his law firm were accused in May of negligence and breach of duty in their handling of a probate case.

The Republican candidate, Gentner Drummond, has acknowledged the probate case was filed in the wrong county but says it wasn't his fault.

"The attorney responsible for that error is no longer employed by the Drummond law firm," his campaign said Sunday.

Making the accusation is a widow, Beverly Sue Allen Walker. She has demanded his Tulsa firm, Drummond Law, return their $20,000 payment for legal work on the case.
