An Oklahoma appeals court has dismissed the appeal of a former prison warden's wife who was convicted of helping a convicted killer escape, and her defense attorney said Tuesday he plans to ask the U.S. Supreme Court to look into the case.

The Oklahoma Court of Criminal Appeals dismissed Bobbi Parker's appeal after denying her more time to purchase a transcript of her four-month trial that is estimated to cost $100,000. The court also refused to declare Park indigent, which would have allowed her to bill the state for the transcript.

Parker was convicted of helping Randolph Franklin Dial escape from the Oklahoma State Reformatory more than 17 years ago, and she spent about seven months in prison. Prosecutors said she fell in love with Dial while they worked in a prison pottery program, but Parker maintains Dial forced her to help him escape and then held her hostage for more than 10 years before they were found.
