Lawyers for Ralph "Bucky" Phillips are moving forward with an appeal of his conviction for killing a state trooper during the largest manhunt in New York history.

Phillips claims he pleaded guilty to a litany of criminal charges, including murder and escape, because he got bad advice from a court-appointed lawyer. His current attorneys will ask for his convictions to be overturned so he can stand trial.

Lawyers are scheduled to argue on Phillips' behalf before the Appellate Division of state Supreme Court in Rochester on Oct. 20.

While on the run for five months after escaping from jail, Phillips shot two troopers who were staking out his ex-girlfriend's home, and one died. He was sentenced in December 2006 to life in prison.
