Scambio d'accuse

i am in the tenth grade at Barbe high school and i met Kerry myers today. we took a class trip to Angola, and he was one of our speakers. he said he was a trustee there, meaning that he hasn't broken any "laws" or rules that they have there at the jail and hasn't been in trouble since he was arrested. he seemed incredibly intelligent, and mentioned that he had a masters in mass communication. at the end of his speaking, he allowed questions, and when someone asked "what are you in for?" and he answered "second degree murder", i was shocked. he seemed very nice and even made a few jokes. i never would have guessed if he hadn't have told us. i got off the bus from Angola about 2 hours ago, and immediately went to Google to find out more, and realized there was an entire movie based on this man that spoke to us. if anyone knows more and might be able to tell me where i can watch this movie, please let me know.
