A defense lawyer is telling an Alabama appeals court that the state is at risk of executing an innocent man.

The arguments come four days after Anthony Ray Hinton was freed from death row when new ballistics tests contradicted the only evidence connecting him to two slayings.

A lawyer for death row inmate Bill Kuenzel on Tuesday told the Alabama Court of Criminal Appeals that he received an unjust trial.

Kuenzel was convicted in the 1987 shooting death of a store clerk. Lawyer David Kochman says prosecutors never disclosed that a teenager who placed Kuenzel at the scene initially told the grand jury that she wasn't sure who she saw.

Assistant Attorney General Clay Crenshaw said there was other evidence that could back up the testimony.
