He pled guilty without bargaining for life without parole?
Maybe his appeal should have been based on inadequate legal representation.
He was able to get outside as part giving this information. He later complained in Angola State Prison that he had been tricked.
This was a case where a guy ran into a young woman on a bicycle (disabling the bicycle) as an excuse to give her a ride.
He made the mistake of pulling knife on the girl, which she used on him, and cut him up very badly. After he killed her, he went over 100 miles away in New Orleans for medical treatment, claiming he had been mugged.
