Gribble wielded a knife and co-conspirator Steven Spader a machete in the attacks that killed Kimberly Cates and maimed her 11-year-old daughter, Jaimie. Both men are serving life sentences without possibility of parole.

Among other claims, Gribble’s lawyers say prosecutors appealed to the emotions of jurors during final arguments and highlighted Gribble’s failure to call an expert witness on insanity.
